My cursor (COBOL PROG):
Code:

EXEC SQL
   DECLARE C1 CURSOR WITH HOLD FOR
     SELECT ROW_A
           ,ROW_B
           ,ROW_C
       FROM TABLE_A
END-EXEC

During the process I might insert rows into TABLE_A but those rows can not appear in my cursor when I fetch it.
I need it WITH HOLD because I have to commit the inserts and maintain the cursor opened.
I don't want to use timestamp as a flag in the WHERE clause.

Any help.
Thanks a lot.

prog_mario,

Change the cursor definition to INSENSITIVE SCROLL CURSOR which will have the following effect

The size, the order of the rows, and the values for each row of the result table do not change after the application opens the cursor.
