Re: Accessing NEW.x values from within stored procedures called by triggers

[Roland Bouman]

Did you try it like this:

declare new_col int;
set new_col := new.col
call check_data(new_col);
set new.col := new_col;

(where
procedure check_data is like (INOUT new_col int)
)
?

(In my experience, parameters of sp's are not limited to @ variables, you can use 'normal' sp variables.)
