Make a SQL Query parameterize at run time with dynamic columns and values like an IN Clause()

I need to use parameterized queries, but the problem the column and values are dynamic.

It might be 5 columns with column 1: 10 values ; column 2: 20 values ; column 3: 1 value ; column 4: 9 values ; column 5 100 values.

     DashboardSqlDataSource dataSource = (DashboardSqlDataSource)dashboard.DataSources[0];
            CustomSqlQuery salesPersonQuery = (CustomSqlQuery)dataSource.Queries[0];
            salesPersonQuery.Parameters.Add(new QueryParameter("startDate", typeof(Expression), 
                new Expression("[Parameters.yearParameter] + '/01/01'")));
            salesPersonQuery.Parameters.Add(new QueryParameter("endDate", typeof(Expression), 
                new Expression("[Parameters.yearParameter] + '/12/31'")));
            salesPersonQuery.Sql = "select * from SalesPerson where OrderDate between @startDate and @endDate";

Above is what the code might look like.

Would after the WHERE need to be an IN clause? What is the best and most efficient way to do this?
