SPOPS::Import::DBI::TableTransform::Pg - Table transformations for PostgreSQL

SYNOPSIS

Top

 my $table = qq/
   CREATE TABLE blah ( id %%INCREMENT%% primary key,
                       name varchar(50) )
 /;
 my $transformer = SPOPS::Import::DBI::TableTransform->new( 'pg' );
 $transformer->increment( \$table );
 print $table;

 # Output:
 # CREATE TABLE blah ( id INT primary key,
 #                     name varchar(50) )

DESCRIPTION

Top

PostgreSQL-specific type conversions for the auto-increment and other field types.

METHODS

Top

increment

Returns 'INT NOT NULL' -- relying on the sequence autocreated by 'SERIAL' can get you into trouble since long table names get truncated. Just create your own sequence and specify it in the 'sequence_name' key of your object config (see SPOPS::DBI::Pg).

increment_type

Returns 'INT'

datetime

Returns 'TIMESTAMP'

BUGS

Top

None known.

TO DO

Top

Add hook for extra statement

Since PostgreSQL supports a sequence-based increment type, think about adding a hook for an extra statement to be registered and modifying '%%INCREMENT%%' to be 'INT NOT NULL' and the extra statement to create a sequence of a given name.
