PHP Warning: SQL error: , SQL state 00000 in SQLColumns

Dear All,

I have been continually getting the error:

when I try and use the odbc_columns command on an Access Database.

For example:

$conn = odbc_connect("MyDragonNet", "", "") or die(odbc_error_msg());
$cols = odbc_columns($conn, "%", "", "users") or die(odbc_errormsg());

does not work (I have tried changing parameters to blank strings or back to "%" with no effect

The following code DOES work:

$conn = odbc_connect("MyDragonNet", "", "") or die(odbc_error_msg());
$cols = odbc_columns($conn) or die(odbc_errormsg());

So it is only when I try and specfiy a table.

Does anyone have any idea?

Thanks in advance,

Justin Hardman
