Solution 1

From the exception, it is quite clear that you are deleting data from one table, which has a reference in another table.

The constraint is FK_Table_search. So check this constraint and find out the related table to which it is related.

The related column is searchID.

After finding the table to which it is related, you need to delete that related record first and then delete from the table you are trying. So, you will need two DELETE queries.

-> First one for Child table/Related table.
-> Second one for the Parent table.

Instead of two DELETE queries, he could also use an ON DELETE CASCADE for the constraint.

Yes that would be good. Can you give me one example how exactly it works ?
I don't know about it. You can also give any reference tutorial, if you have or you can find.

Thanks a lot,
Tadit
