Manually increase 100 record limit

Hi experts

Am working ASP/SQL website and redering database records using this awesome DataTables plugin.

But as i constated, it's fetching only 100 records. I have 1500+ records. But it only showing 100 records.

Showing 1 to 25 of 100 entries

How can i increase MANUALLY the limit ?

BTW: i cannot use the api, or php or Json. Am getting the records directly from DB to HTML
