Duplicate of: TSQL varchar string manipulation

I’m building a dynamic SQL statement out of parameters from a reporting services report. Reporting services passes MutiValue Parameters in a basic CSV format. For example a list of states may be represented as follows: AL,CA,NY,TN,VA

In a SQL statement this is OK: 

WHERE customerState In (@StateList)

However, the dynamic variant isn’t OK:

SET @WhereClause1 = @WhereClause1 + 'AND customerState IN (' + @StateList + ') '

This is because it translates to (invalid SQL):

AND customerState IN (AL,CA,NY,TN,VA)

To process it needs something like this:

AND customerState IN ('AL','CA','NY','TN','VA')

Is there some cool expression I can use to insert the single quotes into my dynamic SQL?

  1. This takes care of the middle:

    SET @StateList = REPLACE(@StateList, ‘,’, ”’,”’)

    Then quote the edges:

    SET @WhereClause1 = @WhereClause1 + ‘AND customerState IN (”’ + @StateList + ”’) ‘
