If your database does not support the column field notation described above, an alternative notation is supported. WDB automatically detects if such a function is defined in the DBI and uses this second notation. To give you an idea of what it takes to write a DBI file I have included the Sybase DBI file below. As you can see it is simply an encapsulation of the sybperl functions. This function is added for efficiency only.
Valid arguments are mdy, dmy, ymd, ydm, myd, dym.
