Event scheduler in mysql

Question

Create EVENT event_test_name ON SCHEDULE EVERY 1 MINUTE STARTS '2010-09-02 12:10:15' ON COMPLETION NOT PRESERVE ENABLE 
DO 
SET Total=-1;
SET Total = (SELECT COUNT(0) FROM schema1.table1);
SELECT Total;
 IF Total >50000 THEN
insert into schema2.table1 (column1) 
select schema1.table1.column1 from schema1.table1;
end if;

This is the event scheduler i am writing for mysql, but i keep getting incorrect syntax line near if statemnet, any help will be highly helpful.

You have to preface your variables with @, otherwise MySQL will assume they're system variables (and Total isn't one of those) or column names in a table, so...

...
SET @Total=-1;
SET @Total = (SELECT ...);
SELECT @Total;
IF @Total > ...

and so on.
