hi Please can anyone help? I have firebird db and I have 150 tables. I need to update some field with query. This snetence is just works fine, what I need is: I need to update all the tables. UPDATE MYTABLE SET TBL_FIELD = 'Man' WHERE TBL_FIELD = 'Women' Code (markup): When I put all table names like this one UPDATE MYTABLE,YOURTABEL, HISTABLE,BESTTABE etc. this time sql error happens because not all the tables have this field TBL_FIELD What is the easiest way to do this. thank you in advance.
