No association exists between the PP2 connection to the database made at precompile time and the connection made by an application at execution time. Embedded LOGON and CONNECT statements have no effect on the PP2 connection. Conversely, tdpid and userid PP2 options do not affect the application logon at execution time. For more information, see USERID(userid[,password[,accountid]])-u userid[,password[,accountid]].
- tdpid
- userid
- Password for the specified userid
If a tdpid is not specified, the connection is made using the system default. The runtime returns a positive SQLCODE value and sets SQLWARN0 and SQLWARN2 to ‘W’.
The following table lists the system defaults for IBM mainframes and workstation-attached systems.
| Platform | Default tdp |
|---|---|
| IBM Mainframe | The default tdp is obtained from the HSHSPB data area module (see Teradata® Call-Level Interface Version 2 Reference for Mainframe-Attached Systems, B035-2417). |
| Workstation-Attached System | The mtdpid is obtained from the user-defined clispb.dat file or the CLI2SPB data area. |
