I just cut-n-pasted from above:

SET @VARBINARY = CONVERT(VARBINARY (16),'0x0000000000018662',1)

RE: Convert binary string to binary

Lynn Pettis (5/9/2013)
When I run the following in SQL Server 2008 R2:
DECLARE @VARBINARY VARBINARY (16)
SET @VARBINARY = CONVERT(VARBINARY (16),'0x0000000000018662',1)
SELECT @VARBINARY;
go
DECLARE @VARBINARY VARBINARY (16)
SET @VARBINARY = CONVERT(VARBINARY (16),'0x0000000000018662',0)
SELECT @VARBINARY;
go
I get;
0x0000000000018662
0x30783030303030303030303030313836
Same here.

I have a string: '0x0000000000018662' that I want to "use" as a binary: 0x0000000000018662. CONVERT/CAST does not work because, I think, it's converting byte by byte the binary/ascii representation...

RE: Query seems to be constrained by single core CPU in multiple core server - any suggestions?

Thanks for the feedback, and you're welcome. An actual plan for the revised query would be very interesting - if you have the time.
