VB.net Excel Add-in SQL Compare two columns for match in string regardless of case


I have two columns in separate table that contain names. My problem is that the cases differ, for instance the name
"John Cooper" in the one column ad in the second table it may appear as "JOHN COOPER". What SQL code would I use to ignore case sensitivity. I am currently using the following code:

    sSQL = "Select Distinct [LINK ID] From [BANK] Where [DESCRIPTION] = '" & oBankDescription & "'

You can try many things but the simplest would be to convert both in same case

"Select Distinct [LINK ID] From [BANK] Where lower([DESCRIPTION]) =  Convert to lower '" & oBankDescription & "'

By doing conversion both side you can get your results.

Other thing you can change the Collation of SQL to

example SQL_Latin1_General_CP1_CI_AS - In this CI stands for Case Insensitive which is by default

You can convert both strings to upper case or lower case, so you can use:

 sSQL = "Select Distinct [LINK ID] From [BANK] Where UPPER([DESCRIPTION]) = '" & oBankDescription.ToUpper() & "'

That will match all the cases.

Hope that helps.
