Status: Open
Bug Type: ODBC related
Operating System: Linux
PHP Version: 5.2.3
New Comment:
I have examined all functions which take the cat argument now, which
are:
- odbc_tables
- odbc_columns
- odbc_columnprivileges
- odbc_foreignkeys
- odbc_primarykeys
- odbc_procedurecolumns
- odbc_procedures
- odbc_specialcolumns
- odbc_statistics
- odbc_tableprivileges
Most of these functions need to have cat == NULL (as long as one
doesn't want to specify a catalog) with the Oracle ODBC driver.
Interestingly, the follow functions don't have this requirement:
- odbc_tables
- odbc_procedurecolumns
- odbc_procedures
So I have created a patch now which sets cat to NULL for the
functions which require it. The patch is available at
http://www.bettina-attack.de/jonny/php-5.2.3-oracle_compat.diff

Argh. Same problem with odbc_primarykeys(). Will examine the other
functions also and create a new patch...

Tested with MyODBC as well, no problems!

I've tested IBM DB2 (iSeries ODBC driver from IBM), MS SQL
(FreeTDS), Sybase (FreeTDS) and Oracle (native ODBC driver from
Oracle). Moreover, NULL is also already passed when odbc_columns()
is called with only one parameter.
The patch may appear ugly but it's the same style as the Access
workaround. IMHO it would be cleaner to allow passing a PHP-null to
actually become a C-NULL, i.e. not forcing the String cast for null
values, but that would be much more intrusive!

Are you sure it doesn't break the other possible drivers..?
