I noticed that you have "using" inside the InternalUpdateByParameter. An expression that returns a value of type boolean. Only rows for which this expression returns true will be updated. The row to be updated is the one most recently fetched from this cursor.

The expression can use any column names of the table or table s listed in FROM. The count is the number of rows updated.

If count is 0, no rows matched the condition this is not considered an error. When using FROM you should ensure that the join produces at most one output row for each row to be modified. In other words, a target row shouldn't join to more than one row from the other table s. If it does, then only one of the join rows will be used to update the target row, but which one will be used is not readily predictable.

Because of this indeterminacy, referencing other tables only within sub-selects is safer, though often harder to read and slower than using a join.
