Subject: Re: DBD::Sybase and SQL_DATA_TYPE
Date: Mar 15 2005 12:23PM

DBD::Sybase relies on Sybase's sp_datatype_info proc to get the data for
type_info_all.

A quick check on 12.5.0.3 shows that sp_datatype_info returns NULL values
for SQL_DATA_TYPE, hence the behavior that you see.

In order to fix it you'd have to fill in the SQL_DATA_TYPE column somehow,
possibly from the TYPE_NAME column - although that means that you get the
Sybase typenames, and not generic SQL types (assuming a good match exists).

The required changes need to be applied in the type_info_all subroutine in
Sybase.pm - you are welcome to submit a patch :-)

Subject:    DBD::Sybase and SQL_DATA_TYPE


I note that with DBD::Sybase when using $sth->{TYPE} and type_info() to
look up the datatypes of columns in a query result, the SQL_DATA_TYPE
is always undef.  I think it usually contains a bit of SQL like
'varchar(10)'.  How difficult would it be to add this?
