Using Postgres as a data source and create mutli value selection in power builder

Anonymous Hello, Please see more details below:

1. I am connecting to an ODBC connection type using an Amazon Redshift driver as a connection string

2. Within the query I use a ? next to the where clause to be able to use the parameter. This was the only way I was able to get the parameters to work using a ODBC connection type. for SQL server I use  @ and I am able to select multiple filters. 

      The query is select multiple fields from table where market in ? (This is the parameter symbol)
3. The parameter properties are the same as the below screenshot:

4. when I try to test the report I am trying to select multiple years or markets. The below case is the markets:

5. When I run the view I get the below error message:

What is the best way to allow multiple selections using a ODBC connection? 

Anonymous The documentation seems to be geared towards SQL Server. I was wondering how to do the same thing connecting to ODBC. Is there any documentation that shows how to connect to other databases besides SQL Server?
