NAME

       SQL::Translator::Parser::SQLite - parser for SQLite

SYNOPSIS

	 use SQL::Translator;
	 use SQL::Translator::Parser::SQLite;

	 my $translator = SQL::Translator->new;
	 $translator->parser("SQL::Translator::Parser::SQLite");

DESCRIPTION

       This is a grammar for parsing CREATE statements for SQLite as described here:

	   http://www.sqlite.org/lang.html

       CREATE INDEX

       sql-statement ::=
	   CREATE [TEMP | TEMPORARY] [UNIQUE] INDEX index-name
	    ON [database-name .] table-name ( column-name [, column-name]* )
	    [ ON CONFLICT conflict-algorithm ]

       column-name ::=
	   name [ ASC | DESC ]

       CREATE TABLE

       sql-command ::=
	   CREATE [TEMP | TEMPORARY] TABLE table-name (
	       column-def [, column-def]*
	       [, constraint]*
	    )

       sql-command ::=
	   CREATE [TEMP | TEMPORARY] TABLE table-name AS select-statement

       column-def ::=
	   name [type] [[CONSTRAINT name] column-constraint]*

       type ::=
	   typename |
	    typename ( number ) |
	    typename ( number , number )

       column-constraint ::=
	   NOT NULL [ conflict-clause ] |
	   PRIMARY KEY [sort-order] [ conflict-clause ] |
	   UNIQUE [ conflict-clause ] |
	   CHECK ( expr ) [ conflict-clause ] |
	   DEFAULT value

       constraint ::=
	   PRIMARY KEY ( name [, name]* ) [ conflict-clause ]|
	   UNIQUE ( name [, name]* ) [ conflict-clause ] |
	   CHECK ( expr ) [ conflict-clause ]

       conflict-clause ::=
	   ON CONFLICT conflict-algorithm

       CREATE TRIGGER

       sql-statement ::=
	   CREATE [TEMP | TEMPORARY] TRIGGER trigger-name [ BEFORE | AFTER ]
	   database-event ON [database-name .] table-name
	   trigger-action

       sql-statement ::=
	   CREATE [TEMP | TEMPORARY] TRIGGER trigger-name INSTEAD OF
	   database-event ON [database-name .] view-name
	   trigger-action

       database-event ::=
	   DELETE |
	   INSERT |
	   UPDATE |
	   UPDATE OF column-list

       trigger-action ::=
	   [ FOR EACH ROW | FOR EACH STATEMENT ] [ WHEN expression ]
	       BEGIN
		   trigger-step ; [ trigger-step ; ]*
	       END

       trigger-step ::=
	   update-statement | insert-statement |
	   delete-statement | select-statement

       CREATE VIEW

       sql-command ::=
	   CREATE [TEMP | TEMPORARY] VIEW view-name AS select-statement

       ON CONFLICT clause

	   conflict-clause ::=
	   ON CONFLICT conflict-algorithm

	   conflict-algorithm ::=
	   ROLLBACK | ABORT | FAIL | IGNORE | REPLACE

       expression

       expr ::=
	   expr binary-op expr |
	   expr like-op expr |
	   unary-op expr |
	   ( expr ) |
	   column-name |
	   table-name . column-name |
	   database-name . table-name . column-name |
	   literal-value |
	   function-name ( expr-list | * ) |
	   expr (+) |
	   expr ISNULL |
	   expr NOTNULL |
	   expr [NOT] BETWEEN expr AND expr |
	   expr [NOT] IN ( value-list ) |
	   expr [NOT] IN ( select-statement ) |
	   ( select-statement ) |
	   CASE [expr] ( WHEN expr THEN expr )+ [ELSE expr] END
