It seems that the IDENTITY property was removed on the ID column.MrJKerl, that's what I get after executing your line :
Msg 8106, Level 16, State 1, Line 1
Table '_RefTeleport' does not have the identity property. Cannot perform SET operation.
My previous line is just applied when you want to insert new row(s) on the table that has a column with IDENTITY property.
So please check your table design again.
