MySQL Trigger: Delete From Table AFTER DELETE

Viewed 114531

Scope: Two tables. When a new patron is created, they have some information about them stored into a 2nd table (This was done using a trigger as well, it works as expected). Here's an example of my table structure and relationship.

Table 1-> patrons

+-----+---------+-----+
+  id +   name  + val +
+=====+=========+=====+
+  37 +  george +  x  +
+-----+---------+-----+
+  38 +  sally  +  y  +
+-----+---------+-----+

Table 2 -> patron_info

+----+-----+----------+
+ id + pid +   name   +
+----+-----+----------+
+  1 +  37 +  george  +
+----+-----+----------+
+  2 +  38 +  sally   +
+----+-----+----------+

The administrator can manage the patrons. When they choose to remove a patron, the patron is removed from the table 1 patrons. At this point, nothing happens to table 2 patron_info.

I'm simply trying to create a trigger to delete from table 2, when table 1 has an item deleted. Here's what I've tried...

Initially, I try to drop the trigger if it exists (just to clear the air)...

DROP TRIGGER IF EXISTS log_patron_delete;

Then I try to create the trigger afterwards...

CREATE TRIGGER log_patron_delete AFTER DELETE on patrons
FOR EACH ROW
BEGIN
DELETE FROM patron_info
    WHERE patron_info.pid = patrons.id
END

At this point, I get a syntax error 1046: Check syntax near END on line 6. I don't know what the error is at this point. I've tried several different variations. Also, am I required to use a delimiter here?

Can anyone help restore my sanity?
