Question

Need to ask about strange behaviour of SQL Server 2005.

What I need is to find records that contain ‘]’ or ‘[‘ in my column

I have a data in column like this

'6b51c65b-5773-415a-aec9-8482c404faef_megas_xlr[1].jpg'

When I run this query

select * from Theme  where BackgroundImageUrl like '%[%'

then no records comes up, but running this below query

select * from Theme  where BackgroundImageUrl like '%]%'

boils following output

'6b51c65b-5773-415a-aec9-8482c404faef_megas_xlr[1].jpg'

What’s wrong in that query? What do I need to do in order to search records having closing or starting brackets []?

EDIT..

For more clarification, here is my test data.
A[1].jpg
B[1.jpg
C1].jpg

And below are results that I got after running following combination

A select BackgroundImageUrl from Theme where BackgroundImageUrl like '%[%'

No Results

B select BackgroundImageUrl from Theme where BackgroundImageUrl like '%]%'

A[1].jpg
C1].jpg

C select BackgroundImageUrl from Theme where BackgroundImageUrl like '%[ [ ]%'

A[1].jpg
B[1.jpg

D select BackgroundImageUrl from Theme where BackgroundImageUrl like '%[ ] ]%'

No Results

What I need is that,
Case 1 : I need all records that contains ‘[‘

Case2 : I need all records that contains ‘]’

Query C fulfills my case 1 but I m not able to get result for my case 2

Answer 1

Well i just discovered my answer.

select * from Theme  where BackgroundImageUrl like  '%\]%' ESCAPE '\'

and

select * from Theme  where BackgroundImageUrl like  '%\[%' ESCAPE '\'
