MiniSQL supports the following data types for an attribute:
- int
- float
- char(n), 1 <= n <= 255
MiniSQL supports the following standard SQL statements.
Note that all SQL statements should END WITH ; and key words should be lowercase.
- create / drop table
create table tableName (attrA int, attrB float unique, attrC char(20), primary key(attrX)); drop table tableName;
- create / drop index
create index indexName on tableName(attrName); drop index indexName;
- select
select attrA, attrB from tableName where attrC = X; select * from tableName;
- insert
insert into tableName values (valueA, valueB, valueC);
- delete
delete from tableName where attrA >= X and attrB < Y;
-
quit
-
import SQL file
exec fileName.sql
MiniSQL consists of seven components:
-
InterpreterInterpret SQL statements, invoke API and return results. -
APIProvide APIs that execute SQL statements, connectInterpreterwith other components. -
Record ManagerCreate / delete files, insert / delete / select tuples. -
Index ManagerCreate / delete B+ trees, insert / delete / select keys. -
Catalog ManagerAccess and manipulate meta-data of tables, attributes and indexes. -
Buffer ManagerRead / write blocks, buffer replacement, record status and locks. -
DB FilesCatalog / data / index files.
