where not exists
(
select seatnumber
from occupation
where shownumber = 1 and performa
INSERT INTO table3
SELECT
tbl1.pk_1, tbl1.pk_2, tbl2.pk_3, tbl1.pk4
FROM
table1 tbl1, table2 tbl2
WHERE
tbl1.pk_1 = 'root' and
NOT EXISTS
(SELECT 1 FROM table3 tbl3
WH

exec(@sql)
Where not exists
(select * from mytable wh
select id from license where not exists(
select a.id from license a,version b, mediapart c where
c.version_id = b.id and b.cntnt_id = a.cntnt_id and c.is_highdef=1);
