do u mean this? update table_name set col1 = valu1, col2 = value2 where staffno = staff_value and period = period_value

Could you give us a little more info? The table structure, some sample rows from that table and an example of what you want the result to look like?

OK.

I have a table IRchair which has columns staffno and clusterid. I am going to add to this table a clumn named period. So I need to bring into this table data for different periods(eg. jan, feb, march ....) without duplicating data.

If a certain staffno exist in that table then I don't want to bring it in again

Can you please give us the table's structure (as a create table statement is easiest), some sample data and what you want it to look like after the update?

Where are you data on the different periods from?

It's called an UPSERT or MERGE... without more data, my only suggestion would be to Google those two words.
