SAS/ACCESS 9.2 for Relational Databases: Reference, Fourth Edition

140 DEGREE= LIBNAME Option 4 Chapter 10NOspecifies that the connection to the DBMS occurs when the libref is assigned by aLIBNAME statement.YESspecifies that the connection to the DBMS occurs when a table in the DBMS isopened.DetailsThe default value of NO is overridden if DBPROMPT=YES.The DEFER= option is ignored when CONNECTION=UNIQUE, because aconnection is performed every time a table is opened.HP Neoview, Microsoft SQL Server, Netezza, ODBC: When you set DEFER=YES, youmust also set the PRESERVE_TAB_NAMES= and PRESERVE_COL_NAMES= optionsto the values that you want. Normally, SAS queries the data source to determine thecorrect defaults for these options during LIBNAME assignment, but settingDEFER=YES postpones the connection. Because these values must be set at the time ofLIBNAME assignment, you must assign them explicitly when you set DEFER=YES.See Also“CONNECTION= LIBNAME Option” on page 108“DBPROMPT= LIBNAME Option” on page 134DEGREE= LIBNAME OptionDetermines whether DB2 uses parallelism.Default value: ANYValid in: SAS/ACCESS LIBNAME statementDBMS support: DB2 under z/OSSyntaxDEGREE=ANY | 1Syntax DescriptionANYenables DB2 to use parallelism, and issues the SET CURRENT DEGREE =’xxx’ forall DB2 threads that use that libref.1explicitly disables the use of parallelism.DetailsWhen DEGREE=ANY, DB2 has the option of using parallelism, when it is appropriate.
