Hi friends

I'm new to SQL

I have two tables in a server(amschn and amsggn).
amschn has got four fields(ecode,day,in_time,out_time)
amsggn has got five fields(ecode,day,in_time,out_time,status)

I want to write a trigger such as when
there is a insert/update(entry) in amschn(in_time) it should update the 'status' field in amsggn as present.

Please help me
