Please make your requirement clear. Can you supplement your requirement with your tables structure and sample data please?

Have you considered using INFORMATION_SCHEMA.TABLES and INFORMATION_SCHEMA.COLUMNS?

As jackv sugegsted, use the system views provided to you by SQL Server. Also, try and avoid using cursors in your code. A WHILE loop will also do the same job for you.

Something like this might work:


create table #myColumns(ColumnHeader varchar(50))

insert into #myColumns(ColumnHeader)
select
	COLUMN_NAME
from
		INFORMATION_SCHEMA.COLUMNS
where
		TABLE_NAME = 'myTable'

Good Luck!

You can probably write a stored proc which takes column name as a param and use system catalog views to check for tables containing this column and perform updation on a while loop for each records returned from view.
