Why do you have the restriction of using the LIKE operator?

But you can accomplish this for example by using the LEFT or the SUBSTRING operator.

Bear in mind thet LEFT and SUBSTRING will not use any suitable indexes (possible performance issues) whereas LIKE will.


Far away is close at hand in the images of elsewhere.

Could do something odd like this: -

WHERE Names = STUFF(Names,1,1,'A')



That'd tell you if the "Names" started with an A.

If you litter your database queries with nolock query hints, are you aware of the side effects?
Try reading a few of these links...

(*) Missing rows with nolock
(*) Allocation order scans with nolock
(*) Consistency issues with nolock
(*) Transient Corruption Errors in SQL Server error log caused by nolock
(*) Dirty reads, read errors, reading rows twice and missing rows with nolock

Why? That's what the LIKE operator is there for, refusing to use the tool most suitable to the problem is strange.

It depends... how slow do you want the code to actually run? :-D

I join Gail in asking, why would anyone want to do such a thing? The courtesy of a reply would be much appreciated.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

It sounds like a homework question to me. The lesson would be that, aside from the obvious approach, there's more than one way to accomplish something. In this case, hopefully eliminating the efficient solution will also be covered in the lesson.
