No, I think the problem is in the concatenation of first part and the result of C# iif. I am guessing C# can not deduce the type of the IIF expression.

The following works fine when I split the above into 2 expressions:

String podText =  ("POD" == bookingType) ? ">0" : "=0";

               sqlCommand.CommandText = "SELECT * FROM dbo.b_sched WHERE " + columnName +
                  @" = @columnValue and start_time IS NOT NULL 
                       AND layer < 7 and is_pod" + podText;
