Question

I am trying to run the following SQL statement:

"SELECT *, (IIF([Field]=TRUE,'StringValue1','StringValue2') AS [NewField] FROM [Table1] ORDER BY [NewField] ASC"

But this gives me an error “Parameter NewField has no default value”. How can I solve it?

I am using Microsoft Access (MDB) database using Jet Engine from Delphi 7.

Thank you!

In the ORDER BY clause, you can reference a column by its ordinal number:

SELECT
  IIF(T.[Field]=TRUE, 'StringValue1', 'StringValue2') AS [NewField],
  T.*
FROM [Table1] T
ORDER BY 1 ASCENDING
