SQL::Translator::Parser::SQLite(3)

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
