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

like-op::=
LIKE | GLOB | NOT LIKE | NOT GLOB
