> ### Specifying Application IDs Explicitly

> ODBC client applications can identify themselves explicitly to the SequeLink service in any of the following ways:

> - Specifying the application ID in the ODBC connection string that is passed to SQLDriverConnect. For example:

> ....;APPID=MyAppID;

> or

> ....;ApplicationID=`MyAppID`;

> where `MyAppID` is the application ID.

> - Specifying the application ID using SQLSetConnectAttr. Immediately after each call to SQLConnect or SQLDriverConnect connecting to the ODBC Client, call SQLSetConnectAttr as shown:

> SQLSetConnectAttr(hdbc, 1053, "`myAppId`", SQL_NTS)

> where `myAppId` is the application ID.

> The SQLSetConnectAttr is defined in sql.h. If an incorrect application ID is specified, the SQLSetConnectAttr fails and all subsequent SQL statements fail.
