Until the other user releases the restrictive lock, youcannot obtain your lock. For example, another user’s table level WRITE lock preventsyou from obtaining a READ lock on the table.Use <strong>SAS</strong>/<strong>ACCESS</strong> locking options only when the standard Teradata standard lockingis undesirable.See AlsoTo apply this option to an individual data set, see the “UPDATE_MODE_WAIT=Data Set Option” on page 398.“Locking in the Teradata Interface” on page 832UPDATE_MULT_ROWS= LIBNAME OptionIndicates whether to allow <strong>SAS</strong> to update multiple rows from a data source, such as a DBMS table.Default value: NOValid in: <strong>SAS</strong>/<strong>ACCESS</strong> LIBNAME statementDBMS support: Aster nCluster, Greenplum, HP Neoview, Microsoft SQL Server, Netezza,ODBC, OLE DB, Sybase IQSyntaxUPDATE_MULT_ROWS=YES | NO
