ID: Q105504

2.50    | 2.50

WINDOWS | MS-DOS kbprg kbfixlist kbbuglist kberrmsg The information in this article applies to:

  • Microsoft FoxPro for Windows, version 2.5
  • Microsoft FoxPro for MS-DOS, version 2.5


A Structured Query Language (SQL) SELECT command that uses a user-defined function (UDF) causes the following error:

   Invalid subscript reference.


Microsoft has confirmed this to be a problem in FoxPro 2.5 for MS-DOS and FoxPro 2.5 for Windows. This problem was corrected in FoxPro 2.5a for MS-DOS and FoxPro 2.5a for Windows.


Steps to Reproduce Problem

Create and run a program with the following code:

   CREATE TABLE equip (equipment C(6))
   INSERT INTO equip (equipment) VALUES ;

   CREATE TABLE timeitem (worksys C(10), jobnum C(9))
   INSERT INTO timeitem (worksys, jobnum) VALUES ;
      ('PAGER', '1')

   SELECT ti.worksys, ti.jobnum, ;
      FROM timeitem ti, equip eq ;
      INTO CURSOR testcur ;
      WHERE = whichval(ti.jobnum,ti.worksys)

   PROCEDURE whichval
   PARAMETERS jobnumval, worksysval
   IF EMPTY(jobnumval)
      RETURN worksysval
      RETURN "job"

The following program error is generated:

   Invalid subscript reference.

The following message is the expected result:

   Selected 0 records in <x> seconds
