134 DBPROMPT= LIBNAME Option 4 Chapter 10DBPROMPT= LIBNAME OptionSpecifies whether SAS displays a window that prompts the user to enter DBMS connectioninformation before connecting to the DBMS in interactive mode.Default value: NOValid in: SAS/ACCESS LIBNAME statementInteraction: DEFER= LIBNAME optionDBMS support: Aster nCluster, DB2 under UNIX and PC Hosts, Greenplum, HPNeoview, Informix, Microsoft SQL Server, MySQL, Netezza, ODBC, Oracle, Sybase,Sybase IQ, TeradataSyntaxDBPROMPT=YES | NOSyntax DescriptionYESspecifies that SAS displays a window that interactively prompts you for the DBMSconnection options the first time the libref is used.NOspecifies that SAS does not display the prompting window.DetailsIf you specify DBPROMPT=YES, it is not necessary to provide connection options withthe LIBNAME statement. If you do specify connection options with the LIBNAMEstatement and you specify DBPROMPT=YES, then the connection option values aredisplayed in the window (except for the password value, which appears as a series ofasterisks). You can override all of these values interactively.The DBPROMPT= option interacts with the DEFER= LIBNAME option to determinewhen the prompt window appears. If DEFER=NO, the DBPROMPT window openswhen the LIBNAME statement is executed. If DEFER=YES, the DBPROMPT windowopens the first time a table or view is opened. The DEFER= option normally defaults toNO but defaults to YES if DBPROMPT=YES. You can override this default by explicitlysetting DEFER=NO.The DBPROMPT window usually opens only once for each time that the LIBNAMEstatement is specified. It might open multiple times if DEFER=YES and the connectionfails when SAS tries to open a table. In these cases, the DBPROMPT window opensuntil a successful connection occurs or you click Cancel .The maximum password length for most of the SAS/ACCESS LIBNAME interfaces is32 characters.Oracle: You can enter 30 characters for the USERNAME and PASSWORD and up to70 characters for the PATH, depending on your platform.Teradata: You can enter up to 30 characters for the USERNAME and PASSWORD.ExamplesIn the following example, the DBPROMPT window does not open when theLIBNAME statement is submitted because DEFER=YES.
