Hello All,

I need your help on the update statement.

I need to update a column of table 1 making a comparison on unique column that exists in two tables, table1 and table2.

Eg:

Table1 Table2
------- ---------
Product_no Product_No
Expiry_date
Status

I need to update the expiry_date on table1 making a join on table1.product_no=table2.product_no.

Need to update the expiry date on table1 for only those produt_no that exists in both tables.

Your help on this would be highly appreciated.

Thanks!
