mysql trigger operand should contain 2 columns

Question

My trigger looks like this:

begin
IF ((NEW.tgebucht >= NEW.tteilnmax) AND (NEW.tgebucht!=0) AND (OLD.tstatus=0)) THEN
  SET NEW.tstatus = 1;
ELSEIF ((NEW.         


        

Answer 1

The syntax looks well. But there is a hidden bug in next line -

IF ((0,25*NEW.tteilnmax)>=(NEW.tteilnmax-NEW.tgebucht)) THEN

You should use '.' as a point delimiter -

IF ((0.25*NEW.tteilnmax)>=(NEW.tteilnmax-NEW.tgebucht)) THEN
