pszConnect

Specifies a connect string. The connect string concatenates information, possibly including a data source name, a user ID valid on the data source, a user authentication string (password, if the data source requires one), and other information.

The whole connect string must be prefixed by the string "ODBC;" (uppercase or lowercase). The "ODBC;" string is used to indicate that the connection is to an ODBC data source. If you do not supply pszConnect, its value defaults to "ODBC;".
