131 # When both a main database table and a TEMP table have the same name,
132 # and a main database trigge is created on the main table, the trigger
133 # is incorrectly bound to the TEMP table. For example:
134 #
135 # CREATE TABLE t1(x);
136 # CREATE TEMP TABLE t1(x);
137 # CREATE TABLE t2(z);
138 # CREATE TRIGGER main.r1 AFTER INSERT ON t1 BEGIN
139 # INSERT INTO t2 VALUES(10000 + new.x);
140 # END;
141 # INSERT INTO main.t1 VALUES(3);
142 # INSERT INTO temp.t1 VALUES(4);
143 # SELECT * FROM t2;
144 #
145 # The r1 trigger fires when the value 4 is inserted into the temp.t1
146 # table, rather than when value 3 is inserted into main.t1.
