Hi, it seems that I did not describe my problem understandable enough. So let me rephrase it. Clarification: The field in question does not contain a '/'. Test statement: ====================== Select count(*) From table Where Mailordernocustomerupper Like '%GF/_2%' Escape '/' And Warehousesiteid In (4) And Status<99 And Clientid In (6); ====================== Result in SQL*Developer: COUNT(*) ---------- 6 Result in SQL*Plus: COUNT(*) ---------- 14 Where does the different behaviour come from?
