Is it possible to pass the NEW and the OLD tables from a trigger into a procedure in MySQL? -


is possible pass new , old tables trigger procedure in mysql? suspect no, since there no such datatype table procedure accepts. workarounds possible?

ideally this:

create trigger product_log after update on product   each row begin     call logchanges(old, new);   end;

you can explicitly pass each field:

call logchanges(old.cola, old.colb, new.cola, new.colb);

or if logchanges must sufficiently generic can handle such calls different tables, 1 concatenate field values single string using suitable delimiter (e.g. unit separator):

call logchanges(concat_ws(char(31), old.cola, old.colb),                 concat_ws(char(31), new.cola, new.colb));

or if data types must preserved, 1 insert records temporary logchanges reads.
