Steps to Reproduce Behavior

  1. In Visual Fox Pro, create a program.
  2. Add the following code to the program:
    SET SAFETY OFF
    SET COLLATE TO "General"
    CREATE TABLE test (nID N(5))
    FOR T=1 TO 10000
    	INSERT INTO test VALUE (T)
    ENDFOR
    SELECT * FROM test WHERE nID NOT IN (SELECT * FROM test)
    SET SAFETY ON
    ? RECCOUNT()
    CLOSE ALL
    DELETE FILE test.DBF
    					
  3. Run the program file.
Note that the SELECT-SQL statement and RECCOUNT() function return 24 records, when no records should be returned.
