The Customer "Ship To" fields are:-

ShipAddressAddr1 - 41 Character String
ShipAddressAddr2 - 41 Character String
ShipAddressAddr3 - 41 Character String
ShipAddressAddr4 - 41 Character String
ShipAddressCity - 31 Character String
ShipAddressState - 21 Character String (USA only - otherwise ShipAddressCounty)
ShipAddressPostalCode - 13 Character String
ShipAddressCountry Varchar - 31 Character String

To see how these fields map to QuickBooks see:

http://www.qodbc.com/docs/html/qodbc/20/tables/qbview_d_customer.asp?qbviewd_id=22

When you mouse over the "Ship To" names you we see the corresponding spot in the QuickBooks entry screen.

If you're asking how can you control what information QuickBooks operators put where?, the answer is that you can't!

However, String Functions can be used in QODBC to obtain various results in your SQL statements to build more meaningful "Ship To" address lines in your application, for example:-

CONCAT(string_exp1, string_exp2) - Returns a character string that is the result of concatenating string_exp2 to string_exp1. If the column represented by string_exp1 or string_exp2 contains a NULL value, a NULL value will be returned.

Example:
SELECT {fn CONCAT(“ShipAddressState”, “ShipAddressPostalCode”)} AS “ST Zip”, “Name” FROM Customer

Returns:
ST Zip     Name
CA94326 Abercrombie, Kristy
CA94327 2nd story addition
CA94482 2nd story addition
CA94326 2nd story addition
CA94482 155 Wilks Blvd.
CA94482 75 Sunset Rd.

or even better, you can add the insert function to put spaces where you need them before the fields you concat:

SELECT {fn CONCAT("ShipAddressState", {fn INSERT("ShipAddressPostalCode", 1, 0, ' ')} )} AS "ST Zip", "Name" FROM Customer

Returns:
ST Zip       Name
CA 94326 Abercrombie, Kristy
CA 94327 2nd story addition
CA 94482 2nd story addition
CA 94326 2nd story addition
CA 94482 155 Wilks Blvd.
CA 94482 75 Sunset Rd.

INSERT(string_exp1, start, length, string_exp2) - Returns a character string where length characters have been deleted from string_exp1 beginning at start and where string_exp2 has been inserted into string_exp1, beginning at start.

Note: QODBC users outside USA need to use "ShipAddressCounty" instead of "ShipAddressState"
