+# When both a main database table and a TEMP table have the same name,

+#   CREATE TEMP TABLE t1(x);
+#   CREATE TABLE t2(z);
+#   CREATE TRIGGER main.r1 AFTER INSERT ON t1 BEGIN

+#   INSERT INTO temp.t1 VALUES(4);
+#   SELECT * FROM t2;

+#    CREATE TRIGGER xyz.trig BEFORE UPDATE ON xyz.tab BEGIN ...
