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 [TEMP | TEMPORARY] VIEW view-name AS select-statement
ON CONFLICT clause
conflict-clause ::=
ON CONFLICT conflict-algorithm
