Hi,
the Database Handle Attributes
Name
and
pg_db
return different values:
Name gives dbname=MyDatabase
whereas
pg_db gives MyDatabase
for a dbh created with a connect(dbi:Pg:dbname=Mydatabase).
In older DBD::Pg versions, namely <2.0.0 andd before, the Name attribute
returned the database name without the leading dbname= (it behaved just like
pg_db does now).
Looking at the documentation of DBI.pm, the current behaviour of Name actually
seems to be correct:
Name (string)
Holds the "name" of the database. Usually (and recommended to be)
the same as the "dbi:DriverName:..." string used to connect to the
database, but with the leading "dbi:DriverName:" removed.
It would be useful to document the difference in behaviour of Name and pg_db
in the DBD::Pg documentation. Currently the difference is not visible:
Name (string, read-only)
Returns the name of the current database.
and
pg_db (string, read-only)
DBD::Pg specific attribute. Returns the name of the current database.
May be even a note pointing out the change towards DBD::PG version <= 2.0.0
(where this was changed according to the CHANGES file) would be useful.
Cheers,
Fritz
