IF UPDATE(@column_name)

IF UPDATE(@column_name)

am 03.08.2007 18:44:41 von Ben Wrigley

I would like to know if it is possible to use a variable to use with
the IF UPDATE(column) statement. Only, the column should be a variable
[e.g. IF UPDATE(@column_name)] which should be substituted at run-time
with the real column name.

TIA

Hi ben,

That's not possible. You might want to look at COLUMNS_UPDATED()
function instead.

Or better yet, explain here what you're trying to do and why you think
that a dynamic IF UPDATE(xxx) would help you. There's a good chance that
there's a better way to do it!

Not possible. UPDATE() can only ever refer to one table. Why wouldn't you
know the names of the columns in your table?

Whenever possible please post enough code to reproduce your problem.
Including CREATE TABLE and INSERT statements usually helps.
State what version of SQL Server you are using and specify the content
of any error messages.
