Question

I have 3 tables

1. ParentTable
2. ChildTable (with column ParentId refering to ParentTable)
3. Recording (with column ParentId refering to own table)

Parent table has a trigger which adds a row into the Recording table.

Child table again has a trigger that appends row in Recording table

Now I get an error that the row was not found in Recording table

The INSERT statement conflicted with the FOREIGN KEY SAME TABLE
constraint

Answer 1

You might be triggering a duplicate ParentID to be inserted into the Recording table. This would be true if your ParentID in the Recording table has a unique key defined on it.

When inserting into the Parent table, you insert a record with a ParentID into Recording. I think your insert a duplicate ParentID on the ChildTable trigger.

Maybe you can provide some more context.

Also, you might want to avoid triggers if possible – which it is most of the time. Using CTE’s and OUTPUT clauses this can help you avoid issues with triggers.
