Do we get a prize for answering correctly?

Remember that "_" is a single character wildcard in SQL, like "?" is in access.

Actually, this looks like the question of the day from yesterday. Why re-post it here?

As Gail said the '_' character is a wildcard.

So if you wanted to only return the 1 record then the LIKE query would be:

select * from #Like_Test where Col1 Like '%Cu[_]%'

The above will only return 1 record by telling SQL that you actually want to search for the '_' by using the [_] inside the search string.

Hope this helps?

Thanks

Kevin

What are you looking for? There was a good explanation in the newsletter for 14th Aug and there's a discussion in the question of the day thread

Oh, and what's your criteria for whether a person is an expert or not?

Not sure what you got here, but questions of the day are built 3-4 weeks ahead of time. Perhaps you saw the question early or it's a coincidence.

In any case, 4 rows returned.

Actually, it didn't. You posted this on the 14th Aug. It was question of the day for the 13th Aug. Hence you posted the question around 24 hours after it was sent to all subscribers in the newsletter.

Coincidence... lol

That really is a stupid question, but not very interesting.

As for the answer, you can just run the code yourself to get that.

Krish-853432 SSC Veteran Points: 299 More actions · Answer 11

Hi,

create table #Like_Test( Col1 varchar(5) )

go

insert #Like_Test values('_Cus')

insert #Like_Test values('Cus_')

insert #Like_Test values('C_us')

insert #Like_Test values('Cus')

insert #Like_Test values('Cu_s')

--select * from #Like_Test

select * from #Like_Test where Col1 Like '%Cu_%'

This query produces 4 results except 'C_us'.

Thanks & Regards,
Krish.

A couple people already have.

As I said, back in my reply to your first post in this thread

Remember that "_" is a single character wildcard in SQL, like "?" is in access.

i.e. It matches any one character.

please explain it in the context of below written script

create table #Like_Test( Col1 varchar(5) )

go

insert #Like_Test values('_Cus')

insert #Like_Test values('Cus_')

insert #Like_Test values('C_us')

insert #Like_Test values('Cus')

insert #Like_Test values('Cu_s')

GO

select * from #Like_Test where Col1 Like '%Cu_%'

How "Col1 Like '%Cu_%' " will work ?
