-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 > What's the easiest way to have perl (using the DBI module) extract table > information? I need to be able to extract column names and types. (Something > like what is given by the MySql "DESCRIBE mytable" command). You want the column_info() method: it's documented in DBI and in DBD::Pg. Usage is something like this: $table = "foobar"; $sth = $dbh->column_info('','',$table,''); $info = $sth->fetchall_arrayref({}); print Dumper $info; In particular, you want the COLUMN_NAME and TYPE_NAME attributes. Also look at the "pg_type" attribute, which gives a friendlier version of TYPE_NAME. - -- Greg Sabino Mullane greg@turnstep.com PGP Key: 0x14964AC8 200505161856 http://biglumber.com/x/web?pk=2529DF6AB8F79407E94445B4BC9B906714964AC8 -----BEGIN PGP SIGNATURE----- iD8DBQFCiSWwvJuQZxSWSsgRAsQCAJ9ovbiDS9Wej34z0BbfKwg81lQCgQCgs+cF HCnypGWqGWE1YAU1y37zsZg= =Mje/ -----END PGP SIGNATURE-----
