Oracle includes a pseudo-column called ROWNUM which allows you to generate a list of sequential numbers based on ordinal row. If your application uses Oracle database, apply your Oracle skills and ROWNUM to limit the number of returned rows. For example, this query selects the TOP 10 rows from a table:
SELECT * FROM (SELECT * FROM my_table ORDER BY col_name_1) WHERE ROWNUM BETWEEN 1 AND 10;
You can impose a NEXT button to the DataWindow. In the Clicked event of the NEXT button, the query changes with ROWNUM increments by 10. Therefore, when the NEXT button is clicked, the DataWindow displays next 10 rows.
