Hi,

I am trying to delete records in the sop10200 table which are related to those in the sop10100 for a particular batch numberonly. The two tables are joined by the sopnumbe field. I have used the following query :

delete sop10200
WHERE exists (select * from sop10100 inner join sop10200 on sop10200.sopnumbe = sop10100.sopnumbe Where bachnumb = 't11')

However, when I run it, it deletes all records in the sop10200 table.

What am I doing wrong ?

it should be


delete s from sop10200 s
WHERE exists (select 1 from sop10100 where sopnumbe = s.sopnumbe and bachnumb = 't11')
