Interface ResultSet
- All Superinterfaces:
AutoCloseable, Wrapper
- All Known Subinterfaces:
CachedRowSet, FilteredRowSet, JdbcRowSet, JoinRowSet, RowSet, SyncResolver, WebRowSet
A table of data representing a database result set, which
is usually generated by executing a statement that queries the database.
A ResultSet object maintains a cursor pointing
to its current row of data. Initially the cursor is positioned
before the first row. The next method moves the
cursor to the next row, and because it returns false
when there are no more rows in the ResultSet object,
it can be used in a while loop to iterate through
the result set.
A default ResultSet object is not updatable and
has a cursor that moves forward only. Thus, you can
iterate through it only once and only from the first row to the
last row. It is possible to
produce ResultSet objects that are scrollable and/or
updatable. The following code fragment, in which con
is a valid Connection object, illustrates how to make
a result set that is scrollable and insensitive to updates by others, and
that is updatable. See ResultSet fields for other
options.
Statement stmt = con.createStatement(
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2");
// rs will be scrollable, will not show changes made by others,
// and will be updatable
The ResultSet interface provides
getter methods ( getBoolean, getLong, and so on)
for retrieving column values from the current row.
Values can be retrieved using either the index number of the
column or the name of the column. In general, using the
column index will be more efficient. Columns are numbered from 1.
For maximum portability, result set columns within each row should be
read in left-to-right order, and each column should be read only once.
For the getter methods, a JDBC driver attempts
to convert the underlying data to the Java type specified in the
getter method and returns a suitable Java value. The JDBC specification
has a table showing the allowable mappings from SQL types to Java types
that can be used by the ResultSet getter methods.
Column names used as input to getter methods are case
insensitive. When a getter method is called with
a column name and several columns have the same name,
the value of the first matching column will be returned.
The column name option is
designed to be used when column names are used in the SQL
query that generated the result set.
For columns that are NOT explicitly named in the query, it
is best to use column numbers. If column names are used, the
programmer should take care to guarantee that they uniquely refer to
the intended columns, which can be assured with the SQL AS clause.
A set of updater methods were added to this interface
in the JDBC 2.0 API (Java 2 SDK,
Standard Edition, version 1.2). The comments regarding parameters
to the getter methods also apply to parameters to the
updater methods.
The updater methods may be used in two ways:
- to update a column value in the current row. In a scrollable
ResultSet object, the cursor can be moved backwards
and forwards, to an absolute position, or to a position
relative to the current row.
The following code fragment updates the NAME column
in the fifth row of the ResultSet object
rs and then uses the method updateRow
to update the data source table from which rs was derived.
rs.absolute(5); // moves the cursor to the fifth row of rs
rs.updateString("NAME", "AINSWORTH"); // updates the
// NAME column of row 5 to be AINSWORTH
rs.updateRow(); // updates the row in the data source
- to insert column values into the insert row. An updatable
ResultSet object has a special row associated with
it that serves as a staging area for building a row to be inserted.
The following code fragment moves the cursor to the insert row, builds
a three-column row, and inserts it into rs and into
the data source table using the method insertRow.
rs.moveToInsertRow(); // moves cursor to the insert row
rs.updateString(1, "AINSWORTH"); // updates the
// first column of the insert row to be AINSWORTH
rs.updateInt(2,35); // updates the second column to be 35
rs.updateBoolean(3, true); // updates the third column to true
rs.insertRow();
rs.moveToCurrentRow();
A ResultSet object is automatically closed when the
Statement object that
generated it is closed, re-executed, or used
to retrieve the next result from a sequence of multiple results.
The number, types and properties of a ResultSet
object's columns are provided by the ResultSetMetaData
object returned by the ResultSet.getMetaData method.

Method Details
-
next
Moves the cursor forward one row from its current position.
A ResultSet cursor is initially positioned
before the first row; the first call to the method
next makes the first row the current row; the
second call makes the second row the current row, and so on.
When a call to the next method returns false,
the cursor is positioned after the last row. Any
invocation of a ResultSet method which requires a
current row will result in a SQLException being thrown.
If the result set type is TYPE_FORWARD_ONLY, it is vendor specified
whether their JDBC driver implementation will return false or
throw an SQLException on a
subsequent call to next.
If an input stream is open for the current row, a call
to the method next will
implicitly close it. A ResultSet object's
warning chain is cleared when a new row is read.
- Returns:
true if the new current row is valid;
false if there are no more rows- Throws:
SQLException - if a database access error occurs or this method is
called on a closed result set
-
close
Releases this ResultSet object's database and
JDBC resources immediately instead of waiting for
this to happen when it is automatically closed.
The closing of a ResultSet object does not close the Blob,
Clob or NClob objects created by the ResultSet. Blob,
Clob or NClob objects remain valid for at least the duration of the
transaction in which they are created, unless their free method is invoked.
When a ResultSet is closed, any ResultSetMetaData
instances that were created by calling the getMetaData
method remain accessible.
Note: A ResultSet object
is automatically closed by the
Statement object that generated it when
that Statement object is closed,
re-executed, or is used to retrieve the next result from a
sequence of multiple results.
Calling the method close on a ResultSet
object that is already closed is a no-op.
- Specified by:
close in interface AutoCloseable- Throws:
SQLException - if a database access error occurs
-
wasNull
Reports whether
the last column read had a value of SQL NULL.
Note that you must first call one of the getter methods
on a column to try to read its value and then call
the method wasNull to see if the value read was
SQL NULL.
- Returns:
true if the last column value read was SQL
NULL and false otherwise- Throws:
SQLException - if a database access error occurs or this method is
called on a closed result set
-
getString
Retrieves the value of the designated column in the current row
of this ResultSet object as
a String in the Java programming language.
- Parameters:
columnIndex - the first column is 1, the second is 2, ...- Returns:
- the column value; if the value is SQL
NULL, the
value returned is null
- Throws:
SQLException - if the columnIndex is not valid;
if a database access error occurs or this method is
called on a closed result set
-
getBoolean
Retrieves the value of the designated column in the current row
of this ResultSet object as
a boolean in the Java programming language.
If the designated column has a datatype of CHAR or VARCHAR
and contains a "0" or has a datatype of BIT, TINYINT, SMALLINT, INTEGER or BIGINT
and contains a 0, a value of false is returned. If the designated column has a datatype
of CHAR or VARCHAR
and contains a "1" or has a datatype of BIT, TINYINT, SMALLINT, INTEGER or BIGINT
and contains a 1, a value of true is returned.
- Parameters:
columnIndex - the first column is 1, the second is 2, ...- Returns:
- the column value; if the value is SQL
NULL, the
value returned is false
- Throws:
SQLException - if the columnIndex is not valid;
if a database access error occurs or this method is
called on a closed result set
-
getByte
Retrieves the value of the designated column in the current row
of this ResultSet object as
a byte in the Java programming language.
- Parameters:
columnIndex - the first column is 1, the second is 2, ...- Returns:
- the column value; if the value is SQL
NULL, the
value returned is 0
- Throws:
SQLException - if the columnIndex is not valid;
if a database access error occurs or this method is
called on a closed result set
-
getShort
Retrieves the value of the designated column in the current row
of this ResultSet object as
a short in the Java programming language.
- Parameters:
columnIndex - the first column is 1, the second is 2, ...- Returns:
- the column value; if the value is SQL
NULL, the
value returned is 0
- Throws:
SQLException - if the columnIndex is not valid;
if a database access error occurs or this method is
called on a closed result set
-
getInt
Retrieves the value of the designated column in the current row
of this ResultSet object as
an int in the Java programming language.
- Parameters:
columnIndex - the first column is 1, the second is 2, ...- Returns:
- the column value; if the value is SQL
NULL, the
value returned is 0
- Throws:
SQLException - if the columnIndex is not valid;
if a database access error occurs or this method is
called on a closed result set
-
getLong

this method returns.
The warning chain is automatically cleared each time a new
row is read. This method may not be called on a ResultSet
object that has been closed; doing so will cause an
SQLException to be thrown.
Note: This warning chain only covers warnings caused
by ResultSet methods. Any warning caused by
Statement methods
(such as reading OUT parameters) will be chained on the
Statement object.
- Returns:
- the first
SQLWarning object reported or
null if there are none
- Throws:
SQLException - if a database access error occurs or this method is
called on a closed result set
-
clearWarnings

reported for this ResultSet object.
- Throws:
SQLException - if a database access error occurs or this method is
called on a closed result set
-
getCursorName
Retrieves the name of the SQL cursor used by this ResultSet
object.
In SQL, a result table is retrieved through a cursor that is
named. The current row of a result set can be updated or deleted
using a positioned update/delete statement that references the
cursor name. To insure that the cursor has the proper isolation
level to support update, the cursor's SELECT statement
should be of the form SELECT FOR UPDATE. If
FOR UPDATE is omitted, the positioned updates may fail.
The JDBC API supports this SQL feature by providing the name of the
SQL cursor used by a ResultSet object.
The current row of a ResultSet object
is also the current row of this SQL cursor.
- Returns:
- the SQL name for this
ResultSet object's cursor
- Throws:
SQLException - if a database access error occurs or this method is called on a closed result setSQLFeatureNotSupportedException - if the JDBC driver does not support
this method
-
getMetaData
Retrieves the number, types and properties of
this ResultSet object's columns.
- Returns:
- the description of this

-
getObject
Gets the value of the designated column in the current row
of this ResultSet object as
an Object in the Java programming language.
This method will return the value of the given column as a
Java object. The type of the Java object will be the default
Java object type corresponding to the column's SQL type,
following the mapping for built-in types specified in the JDBC
specification. If the value is an SQL NULL,
the driver returns a Java null.
This method may also be used to read database-specific
abstract data types.
In the JDBC 2.0 API, the behavior of method
getObject is extended to materialize
data of SQL user-defined types.
If Connection.getTypeMap does not throw a
SQLFeatureNotSupportedException,
then when a column contains a structured or distinct value,
the behavior of this method is as
if it were a call to: getObject(columnIndex,
this.getStatement().getConnection().getTypeMap()).
If Connection.getTypeMap does throw a
SQLFeatureNotSupportedException,
then structured values are not supported, and distinct values
are mapped to the default Java class as determined by the
underlying SQL type of the DISTINCT type.
- Parameters:
columnIndex - the first column is 1, the second is 2, ...- Returns:
- a
java.lang.Object holding the column value
- Throws:
SQLException - if the columnIndex is not valid;
if a database access error occurs or this method is
called on a closed result set
-
getObject
Gets the value of the designated column in the current row
of this ResultSet object as
an Object in the Java programming language.
This method will return the value of the given column as a
Java object. The type of the Java object will be the default
Java object type corresponding to the column's SQL type,
following the mapping for built-in types specified in the JDBC
specification. If the value is an SQL NULL,
the driver returns a Java null.
This method may also be used to read database-specific
abstract data types.
In the JDBC 2.0 API, the behavior of the method
getObject is extended to materialize
data of SQL user-defined types. When a column contains
a structured or distinct value, the behavior of this method is as
if it were a call to: getObject(columnIndex,
this.getStatement().getConnection().getTypeMap()).

before the first row.
An attempt to position the cursor beyond the first/last row in
the result set leaves the cursor before the first row or after
the last row.
Note: Calling absolute(1) is the same
as calling first(). Calling absolute(-1)
is the same as calling last().

row - the number of the row to which the cursor should move.
A value of zero indicates that the cursor will be positioned
before the first row; a positive number indicates the row number
counting from the beginning of the result set; a negative number
indicates the row number counting from the end of the result set- Returns:
true if the cursor is moved to a position in this
ResultSet object;
false if the cursor is before the first row or after the
last row- Throws:
SQLException - if a database access error
occurs; this method is called on a closed result set
or the result set type is TYPE_FORWARD_ONLYSQLFeatureNotSupportedException - if the JDBC driver does not support
this method- Since:
- 1.2
-
relative
Moves the cursor a relative number of rows, either positive or negative.
Attempting to move beyond the first/last row in the
result set positions the cursor before/after the
the first/last row. Calling relative(0) is valid, but does
not change the cursor position.
Note: Calling the method relative(1)
is identical to calling the method next() and
calling the method relative(-1) is identical
to calling the method previous().
- Parameters:
rows - an int specifying the number of rows to
move from the current row; a positive number moves the cursor
forward; a negative number moves the cursor backward- Returns:
true if the cursor is on a row;
false otherwise- Throws:
SQLException - if a database access error occurs; this method
is called on a closed result set or the result set type is
TYPE_FORWARD_ONLYSQLFeatureNotSupportedException - if the JDBC driver does not support
this method- Since:
- 1.2
-
previous
Moves the cursor to the previous row in this
ResultSet object.
When a call to the previous method returns false,
the cursor is positioned before the first row. Any invocation of a
ResultSet method which requires a current row will result in a
SQLException being thrown.
If an input stream is open for the current row, a call to the method
previous will implicitly close it. A ResultSet
object's warning change is cleared when a new row is read.
- Returns:
true if the cursor is now positioned on a valid row;
false if the cursor is positioned before the first row- Throws:
SQLException - if a database access error
occurs; this method is called on a closed result set
or the result set type is TYPE_FORWARD_ONLYSQLFeatureNotSupportedException - if the JDBC driver does not support
this method- Since:
- 1.2

this method is called on a closed result set,
if this method is called when the cursor is not on the insert row,
or if not all of non-nullable columns in
the insert row have been given a non-null valueSQLFeatureNotSupportedException - if the JDBC driver does not support
this method- Since:
- 1.2
-
updateRow
Updates the underlying database with the new contents of the
current row of this ResultSet object.
This method cannot be called when the cursor is on the insert row.

refreshRow
Refreshes the current row with its most recent value in
the database. This method cannot be called when
the cursor is on the insert row.
The refreshRow method provides a way for an
application to
explicitly tell the JDBC driver to refetch a row(s) from the
database. An application may want to call refreshRow when
caching or prefetching is being done by the JDBC driver to
fetch the latest value of a row from the database. The JDBC driver
may actually refresh multiple rows at once if the fetch size is
greater than one.
All values are refetched subject to the transaction isolation
level and cursor sensitivity. If refreshRow is called after
calling an updater method, but before calling
the method updateRow, then the
updates made to the row are lost. Calling the method
refreshRow frequently will likely slow performance.
- Throws:
SQLException - if a database access error
occurs; this method is called on a closed result set;
the result set type is TYPE_FORWARD_ONLY or if this
method is called when the cursor is on the insert rowSQLFeatureNotSupportedException - if the JDBC driver does not support

updater method(s) and before calling
the method updateRow to roll back
the updates made to a row. If no updates have been made or
updateRow has already been called, this method has no
effect.
- Throws:
SQLException - if a database access error
occurs; this method is called on a closed result set;
the result set concurrency is CONCUR_READ_ONLY
or if this method is called when the cursor is
on the insert rowSQLFeatureNotSupportedException - if the JDBC driver does not support
this method- Since:
- 1.2
-
moveToInsertRow
Moves the cursor to the insert row. The current cursor position is
remembered while the cursor is positioned on the insert row.
The insert row is a special row associated with an updatable
result set. It is essentially a buffer where a new row may
be constructed by calling the updater methods prior to
inserting the row into the result set.
Only the updater, getter,
and insertRow methods may be
called when the cursor is on the insert row. All of the columns in
a result set must be given a value each time this method is
called before calling insertRow.
An updater method must be called before a
getter method can be called on a column value.

Updates the designated column using the given input stream. The data will be read from the stream
as needed until end-of-stream is reached.
The updater methods are used to update column values in the
current row or the insert row. The updater methods do not
update the underlying database; instead the updateRow or
insertRow methods are called to update the database.
Note: Consult your JDBC driver documentation to determine if
it might be more efficient to use a version of
updateBlob which takes a length parameter.
- Parameters:
columnIndex - the first column is 1, the second is 2, ...inputStream - An object that contains the data to set the parameter
value to.- Throws:
SQLException - if the columnIndex is not valid; if a database access error occurs;
the result set concurrency is CONCUR_READ_ONLY
or this method is called on a closed result setSQLFeatureNotSupportedException - if the JDBC driver does not support
this method- Since:
- 1.6

getObject
Retrieves the value of the designated column in the current row
of this ResultSet object and will convert from the
SQL type of the column to the requested Java data type, if the
conversion is supported. If the conversion is not
supported or null is specified for the type, a
SQLException is thrown.
At a minimum, an implementation must support the conversions defined in
Appendix B, Table B-3 and conversion of appropriate user defined SQL
types to a Java type which implements SQLData, or Struct.
Additional conversions may be supported and are vendor defined.
- Type Parameters:
T - the type of the class modeled by this Class object- Parameters:
columnIndex - the first column is 1, the second is 2, ...type - Class representing the Java data type to convert the designated
column to.- Returns:
- an instance of
type holding the column value
- Throws:
SQLException - if conversion is not supported, type is null or
another error occurs. The getCause() method of the
exception may provide a more detailed exception, for example, if
a conversion error occursSQLFeatureNotSupportedException - if the JDBC driver does not support
this method- Since:
- 1.7

updateObject
Updates the designated column with an Object value.
The updater methods are used to update column values in the
current row or the insert row. The updater methods do not
update the underlying database; instead the updateRow or
insertRow methods are called to update the database.
If the second argument is an InputStream then the stream must contain
the number of bytes specified by scaleOrLength. If the second argument is a
Reader then the reader must contain the number of characters specified
by scaleOrLength. If these conditions are not true the driver will generate a
SQLException when the statement is executed.
The default implementation will throw SQLFeatureNotSupportedException
- Parameters:
columnIndex - the first column is 1, the second is 2, ...x - the new column valuetargetSqlType - the SQL type to be sent to the databasescaleOrLength - for an object of java.math.BigDecimal ,
this is the number of digits after the decimal point. For
Java Object types InputStream and Reader,
this is the length
of the data in the stream or reader. For all other types,
this value will be ignored.- Throws:
SQLException - if the columnIndex is not valid;
if a database access error occurs;
the result set concurrency is CONCUR_READ_ONLY
or this method is called on a closed result setSQLFeatureNotSupportedException - if the JDBC driver does not
