Note: Applications is the name of table, this table has 4 fields Application ID, Application, Owner, Responsible The New Owner is the name of the textbox that I have created for the user to enter the new Owner.

I just want to update the Owner and Responsible fields Thanks Assuming Owner is a text field you will need the single quotes.

The "tiresome way" is standard SQL and how mainstream RDBMS do it.

With a 100 columns, you mostly likely have a design problem...

also, there are mitigating methods in client tools (eg generation UPDATE statements) or by using ORMs If you need to re-type this several times, you can do like I did once.

Get your columns` names into rows in excel sheet (write down at the end of each column name (=) which is easy in notepad ) on the right side make a column to copy and paste your value that will correspond to the new entries at each column.

Alternatively, the more commonly implemented SQL:92 standard syntax to do this would be: UPDATE t1 set DATA = derived1.
