Using variable to specify 'size' when declaring a VARBINARY
-

문제
In SQL Server (2008 R2), instead of doing this:
DECLARE @testVar VARBINARY(64);
I would like to do this:
DECLARE @varSize INT;
SET @varSize = 64;
DECLARE @testVar VARBINARY(@varSize);
But I get this error:
Incorrect syntax near '@varSize'.
How can I do something like this or force SQL to evaluate @varSize?

For a variable, why don't you just use MAX?
DECLARE @testVar VARBINARY(MAX);
This isn't the 70s anymore. Your system can handle it. In fact if what you want to do were possible, I suspect you'd waste more resources doing that than you would just declaring the variable as MAX in the first place.
