The ROWID value of a temp-table buffer will be different than the ROWID value of a record BUFFER even if the underlying data is identical. This difference exists because the ROWID function relies on the record buffer name.

Expected ABL behavior—ROWID value of a temp-table buffer

The following example shows the standard, expected ABL behavior.

DEFINE VARIABLE rid-1    AS ROWID  NO-UNDO.
DEFINE VARIABLE rid-2    AS ROWID  NO-UNDO.
DEFINE VARIABLE ttHandle AS HANDLE NO-UNDO EXTENT 1.

DEFINE TEMP-TABLE ttCustomer LIKE Sports2000.Customer
  FIELD tRecid       AS INTEGER
  FIELD tRECID_ident AS INTEGER.

ttHandle[1] = TEMP-TABLE ttCustomer:HANDLE.

FIND FIRST Customer WHERE Customer.CustNum = 1 NO-LOCK.
rid-1 = ROWID(Customer).

RUN STORED-PROC send-sql-statement 
  LOAD-RESULT-INTO ttHandle ("select * from customer where custnum = 1").

rid-2 = ROWID(ttCustomer).

IF rid-1 NE rid-2 THEN 
  MESSAGE "The same record but different ROWID's".

The following sections illustrate the differences between the ROWID value of a temp-table buffer and the ROWID value of a record BUFFER so that you can best understand, program for, and leverage the use of the ROWID function with the LOAD-RESULT-INTO clause of the RUN STORED-PROCEDURE command.
