If the CREATE FUNCTION or REPLACE FUNCTION statement specifies a column list for the table function row result, then the table function is said to have a fixed result row specification. The number of result parameters in the table function parameter list matches the number of columns in the column list in the RETURNS TABLE clause of the CREATE FUNCTION or REPLACE FUNCTION statement.

Here is an example of a CREATE FUNCTION statement for a table function with a fixed result row specification:

CREATE FUNCTION getStoreData
  (FileToRead INTEGER)
RETURNS TABLE (StoreNo INTEGER, ItemNo INTEGER, QuantSold INTEGER)
LANGUAGE C
NO SQL
EXTERNAL NAME 'CS!getdata!udfsrc/gs1.c'
PARAMETER STYLE SQL;

In this example, the number of result parameters in the table function parameter list is three.
