[WD20] Extract a filename suffix in a SQL string (4 replies)

Hi,

I have some problems with a part of my own build sql string.

I have to extract the filename suffix

.... FROM Files WHERE WL.ExtractString(Files.Filename,-2147483645,'.') = 'pdf'

The number is the constant for "lastrank". The SQL doesn´t run.

Any idea whats the problem is ?
