An explicit value for the identity column in table 'Table' can only be specified when a column list is used and IDENTITY_INSERT is ON

Question

Does someone know what this error (An explicit value for the identity column in table \'HD_AANVRAAG_FASE\' can only be specified when a column list is used and IDENTITY_INSERT

Answer 1

You're missing a

SET IDENTITY_INSERT HD_AANVRAAG_FASE ON

before you run your insert. That's the exact cause of the error.

That said, inserting identity values explicitly is rare-- for example, used only when copying data from one table to another, or initializing a new table with explicit IDs. Usually you'll just want to omit identity values from your INSERT, which also avoids the error.

Answer 2

Your code contains

SET IDENTITY_INSERT HD_AANVRAAG_FASE OFF at the end

But not a corresponding

SET IDENTITY_INSERT HD_AANVRAAG_FASE ON at the start

why are you explicitly inserting these any way? Is it a synchronization task?

Answer 3

Since you aren't specifying the columns explicitly, I assume @fase_id is being passed into an IDENTITY column, which as the error indicates you can't do unless you force it via IDENTITY_INSERT.

Usually, you let the DB generate this; specify the columns in the INSERT and omit the identity column (and don't try to assign a value). The straight after the INSERT your new id is available as SCOPE_IDENTITY().
