Add record to Database table

Hi ,

I have some trouble about adding record to Z's Database table.

I created a new table and it include a four key parameter and several parameter in this table.

Also i have a internal table and i added new record to this internal table in program.

I want to , add record to this db table from internal table. But when i added new record db table modify specific row, not added new row.

How can i do; when every new row added in my internal table also added my db table like new row ?

Best regards.
