table_reference, table_reference
table_reference [CROSS] JOIN table_reference

table_reference STRAIGHT_JOIN table_reference
table_reference LEFT [OUTER] JOIN table_reference ON conditional_expr

INSERT [INTO] tbl_name [(col_name,...)]
VALUES (expression,...),(...),...

INSERT [INTO] tbl_name [(col_name,...)]
SELECT ...

DELETE [LOW_PRIORITY] FROM tbl_name
[WHERE where_definition]


UPDATE tbl_name SET col_name1=expr1,col_name2=expr2,...
[WHERE where_definition]

Data Definition Language

CREATE TABLE [IF NOT EXISTS] tbl_name [(create_definition,...)] [table_options] [select_statement]

create_definition: col_name type [NOT NULL | NULL] [DEFAULT default_value] [AUTO_INCREMENT] [PRIMARY KEY] [reference_definition]
or PRIMARY KEY (index_col_name,...)
or KEY [index_name] (index_col_name,...)
or INDEX [index_name] (index_col_name,...)
or UNIQUE [INDEX] [index_name] (index_col_name,...)
or [CONSTRAINT symbol] FOREIGN KEY index_name (index_col_name,...) [reference_definition]
or CHECK (expr)

DROP TABLE [IF EXISTS] tbl_name [, tbl_name,...]

ALTER TABLE tbl_name alter_spec [, alter_spec ...]

alter_specification:
ADD [COLUMN] create_definition [FIRST | AFTER column_name ]
or ADD [COLUMN] (create_definition, create_definition,...)
or ADD INDEX [index_name] (index_col_name,...)
or ADD PRIMARY KEY (index_col_name,...)
or ADD UNIQUE [index_name] (index_col_name,...)
or ALTER [COLUMN] col_name {SET DEFAULT literal | DROP DEFAULT}
or CHANGE [COLUMN] old_col_name create_definition
or MODIFY [COLUMN] create_definition
or DROP [COLUMN] col_name
or DROP PRIMARY KEY
or DROP INDEX index_name
or RENAME [AS] new_tbl_name
or table_options

CREATE [UNIQUE] INDEX index_name ON tbl_name (col_name[(length)],... )

DROP INDEX index_name ON tbl_name

CREATE [AGGREGATE] FUNCTION function_name RETURNS {STRING|REAL|INTEGER}
SONAME shared_library_name

DROP FUNCTION function_name

Access Control

GRANT priv_type [(column_list)] [, priv_type [(column_list)] ...]
ON {tbl_name | * | *.* | db_name.*}
TO user_name [IDENTIFIED BY 'password']
[, user_name [IDENTIFIED BY 'password'] ...]
[WITH GRANT OPTION]

REVOKE priv_type [(column_list)] [, priv_type [(column_list)] ...]
ON {tbl_name | * | *.* | db_name.*}
FROM user_name [, user_name ...]

priv_type:

ALL PRIVILEGES FILE RELOAD ALTER INDEX
SELECT CREATE INSERT SHUTDOWN DELETE
PROCESS UPDATE DROP REFERENCES USAGE


Transaction Control
