SPOPS::Import::DBI::TableTransform::Pg - Table transformations for PostgreSQL
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) )
PostgreSQL-specific type conversions for the auto-increment and other field types.
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'
None known.
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.
