NAME

SQL::Translator::Parser::PostgreSQL - parser for PostgreSQL

SYNOPSIS

use SQL::Translator;
use SQL::Translator::Parser::PostgreSQL;

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

DESCRIPTION

The grammar was started from the MySQL parsers. Here is the description from PostgreSQL, truncated to what's currently supported (patches welcome, of course) :

Table: (http://www.postgresql.org/docs/current/sql-createtable.html)

CREATE [ [ LOCAL ] { TEMPORARY | TEMP } ] TABLE table_name (
    { column_name data_type [ DEFAULT default_expr ]
       [ column_constraint [, ... ] ]
    | table_constraint }  [, ... ]
)
[ INHERITS ( parent_table [, ... ] ) ]
[ WITH OIDS | WITHOUT OIDS ]

where column_constraint is:

[ CONSTRAINT constraint_name ]
{ NOT NULL | NULL | UNIQUE | PRIMARY KEY |
  CHECK (expression) |
  REFERENCES reftable [ ( refcolumn ) ] [ MATCH FULL | MATCH PARTIAL ]
    [ ON DELETE action ] [ ON UPDATE action ] }
[ DEFERRABLE | NOT DEFERRABLE ] [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ]

and table_constraint is:

[ CONSTRAINT constraint_name ]
{ UNIQUE ( column_name [, ... ] ) |
  PRIMARY KEY ( column_name [, ... ] ) |
  CHECK ( expression ) |
  EXCLUDE [USING acc_method] (expression) [INCLUDE (column [, ...])] [WHERE (predicate)]
  FOREIGN KEY ( column_name [, ... ] )
   REFERENCES reftable [ ( refcolumn [, ... ] ) ]
    [ MATCH FULL | MATCH PARTIAL ] [ ON DELETE action ] [ ON UPDATE action ] }
[ DEFERRABLE | NOT DEFERRABLE ] [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ]

Index : (http://www.postgresql.org/docs/current/sql-createindex.html)

CREATE [ UNIQUE ] INDEX index_name ON table
    [ USING acc_method ] ( column [ ops_name ] [, ...] )
    [ INCLUDE  ( column [, ...] ) ]
    [ WHERE predicate ]
CREATE [ UNIQUE ] INDEX index_name ON table
    [ USING acc_method ] ( func_name( column [, ... ]) [ ops_name ] )
    [ WHERE predicate ]

Alter table:

ALTER TABLE [ ONLY ] table [ * ]
    ADD [ COLUMN ] column type [ column_constraint [ ... ] ]
ALTER TABLE [ ONLY ] table [ * ]
    ALTER [ COLUMN ] column { SET DEFAULT value | DROP DEFAULT }
ALTER TABLE [ ONLY ] table [ * ]
    ALTER [ COLUMN ] column SET STATISTICS integer
ALTER TABLE [ ONLY ] table [ * ]
    RENAME [ COLUMN ] column TO newcolumn
ALTER TABLE table
    RENAME TO new_table
ALTER TABLE table
    ADD table_constraint_definition
ALTER TABLE [ ONLY ] table
        DROP CONSTRAINT constraint { RESTRICT | CASCADE }
ALTER TABLE table
        OWNER TO new_owner

View :

CREATE [ OR REPLACE ] VIEW view [ ( column name list ) ] AS SELECT query
