Subject Writing data in tables!

I have problems when I'm trying to write data to a table. How are you
supposed to do it???

I have managed to connect to the database (at least I think that I
have) but when I try to write to a table it craches the hole time.

I'm using the isc_dsql_execute_immediate. But I need to use a SQL
with parameters. How does the code look like when you write to a
table in employee.gdb "Any table will do". I will be able to write
let us say 100 new post to it.

Thanks for all the help!
