Creating SumIf function in SQL Server 2012

Question

I need some help building a SQL Server function that acts as a SumIf in Excel, for example

SumIF(Fees.Fee_Amount, Fees.Type =\'Services\' and F         


        

Answer 1

The simplest way would be to SUM a CASE clause, like so:

SUM(CASE WHEN Fees.Type ='Services' and Fees.Fee_Code = 'B01'
         THEN Fees.Fee_Amount
    END) AS ColumnAlias,
