## First some simple tests

select 0<=>0,0.0<=>0.0,0E0=0E0,'A'<=>'A',NULL<=>NULL;
select 1<=>0,0<=>NULL,NULL<=>0;
select 1.0<=>0.0,0.0<=>NULL,NULL<=>0.0;
select 'A'<=>'B','A'<=>NULL,NULL<=>'A';
select 0<=>0.0, 0.0<=>0E0, 0E0<=>'0', 10.0<=>1E1, 10<=>10.0, 10<=>1E1;
select 1.0<=>0E1,10<=>NULL,NULL<=>0.0, NULL<=>0E0;

## Test with tables
##
#
create table t1 (id int primary key, value int);
create table t2 (id int primary key, value int);
#
insert into t1 values (1,null);
insert into t2 values (1,null);
#
select t1.*, t2.*, t1.value=t2.value from t1, t2 where t1.id=t2.id and t1.id=1;
select * from t1 where id =id;
select * from t1 where value = value;
select * from t1 where id = value or value=id;
select * from t1 where value = null;
select * from t1 where (value) = (null);
--error 1064
select * from t1 where ROW(value) = ROW(null);
select * from t1 where (id, value) = (1, null);
drop table t1,t2;

##
create table t1 (a bigint primary key);
