Try using replace function like this:

declare @a varchar(100) = 'akraft,crunckel';

set @a = ''''+replace(@a,',',''',''')+''''

select @a

Hi! Maybe, if you are familiar with 2005, it would be reasonable to start from here.

What's New (SQL Server 2008)

We also may update like this:

with cte as

(

select

rn = row_number() over (partition by ClientKey order by GuarantorKey desc),

*

from

#tmpGuarantor

)

update t

set t.GuarantorKey = cte.GuarantorKey

from

#tmpTest t

join cte on t.ClientKey =...

If we speak for performance aspect, I think it is not parse name, rather it is replace impact, because...

It would be also nice to see actual plan in xml. And maybe some info about a table, e.g. size, structure and indexes.

NULL+123 = NULL

NULL + Anything = NULL.

That's how it works. use isnull function over the fields, like that

isnull(MyField1,0)+isnull(MyField2,0)+...

Thank's for the plans! It is now much more clear!

Well, I think, I figured...

Wait for a moment!

Look at the plan.

Here is what good plan says:

@PayrollID value = (345)

Here is what bad plan says:

Compiled param value = (334329)

Run param value = (345)

Seems there is...

My understanding about parameter sniffing is that the optimizer uses the plan that was compiled after first use, which may not be optimal for subsequent...

Maybe you mean, that you want to execute a cross server query?

You may add linked server. After that you may query remote table specifying 4 part name:

select * from MyServer.MyDatabase.MyScheme.MyTable.
