My last example:
update dbo.Table
set Column = replace(Column, '
', '
')
Will do exactly what you're talking about.
1
2
3
4
5
6
7
Will turn into:
1
2
3
4
5
6
7
Whole table, all at once, all rows.
Matt: On the RBAR thing, it looked to...

In the actual execution, yes, it stops after the first true test in the Case statement. When building the execution plan, it has to check all of them, and...

The only time to compromise on performance is when integrity would be threatened by it. Integrity first, performance second.

With data that doesn't update constantly (like several dozen/hundred/thousand/million changes per hour), this is a pretty common solution.

It sounds like you've got a decent handle on what to do.

And, as per the original post, if you want to keep double-returns, and get rid of single, try something like this:
declare @test-2 varchar(100)
select @test-2 = '1
2
3'
select @test-2 = replace(replace(replace(@test, '
',...

Okay, I have to ask if this is being over-complicated. Why not just:
declare @Test varchar(100)
select @test = '1
2
3'
select @test = replace(@test, '
', '')
select @test
That works for me. I...

Often, SQL Server will reduce the amount of work an inner query does if the outer query can limit the rows for the inner query. I'd have to at...

It looks to me like you're on the right path.
