Mr. (),
Welcome to JavaRanch! We don't have too many rules 'round here, but we do have a naming policuy, which basically asks you to use your real first and last name, or at least something that isn't so obviously fake. Please head over here and fix your display name, pronto!
I'm going to help you out by moving this question to the JDBC forum. Followups there, please.

These are some snippets of code that explains what I'm talking about:
(Prepared Statement)
AddACategory2 = connection.prepareStatement("INSERT INTO TABLE tbl_CategoryOptions (SKU, Category, Size, Color) VALUES (?), (?), (?), (?)");

(Method using Prep Statement)
private void AddCategory(int a, ArrayList b)
{
try{
AddACategory1.setInt(1, a);
AddACategory2.setInt(1, ???);
}


catch(SQLException se){ se.printStackTrace();}
}
I'm pulling in an Int and 3 Strings sequentially from ArrayList b and I need to place them into AddACategory2.....

Drew, three things:
1) Please remove the trailing stuff from your display name, "Drew Dambrell" will do nicely. Thanks.
2) The syntax of the values clause should be values (?,?,?,?)
3) Without knowing what AddACategory2 is, I'm not sure how to answer your question. Given its naming convention, I'd say it's a class name and setInt is a static method. Or is it a badly named variable for a PreparedStatement?
Is it iterating through the array list that you're confused about? Not sure exactly where your issues lie.

This might help get you started:

It's a little hard to tell if this will satisfy your request, since you indicate that the SKU (int) and other values (String) all come from an ArrayList, but in the method you show that the int values is being passed in separately from the ArrayList.
If the int value is being passed in via the ArrayList, it must either be coming across as a String (i.e., "123"), or an Integer (i.e., new Integer(123)).
Also, does the ArrayList contain information for only one entry, or does it contain multiple sets? If you have multiple sets, you'll need some sort of a "for" loop to process them all.
In either case, what I've given should help you get started. Whatever you put into an ArrayList will come out as an "Object" instance, and so much be cast to appropriate data type.
When setting the parameters of a PreparedStatement, the column values are 1-based, but the ArrayList indexes are 0-based.
