# READ_ONLY does nothing to SUPER users
# so we use a non-SUPER one:

set global read_only=1;

create table t3 (a int);
drop table t3;

connect (con1,localhost,test,,test);
connection con1;

# With temp tables updates should be accepted:

create temporary table t3 (a int);

create temporary table t4 (a int) select * from t3;

insert into t3 values(1);

insert into t4 select * from t3;

# a non-temp table updated:
--error 1290

# no non-temp table updated (just swapped):
update t1,t3 set t3.a=t1.a+1 where t1.a=t3.a;
