The LIBNAME Statement for Relational Databases 4 QUALIFY_ROWS= LIBNAME Option 171See AlsoTo apply this option to an individual data set, see the “QUALIFIER= Data SetOption” on page 359.QUALIFY_ROWS= LIBNAME OptionUniquely qualifies all member values in a result set.Default value: NOValid in: SAS/ACCESS LIBNAME statementDBMS support: OLE DBSyntaxQUALIFY_ROWS=YES | NOSyntax DescriptionYESspecifies that when the OLE DB interface flattens the result set of an MDXcommand, the values in each column are uniquely identified using a hierarchicalnaming scheme.NOspecifies that when the OLE DB interface flattens the result set of an MDX command,the values in each column are not qualified, which means they might not be unique.DetailsFor example, when this option is set to NO, a GEOGRAPHY column might have a valueof PORTLAND for Portland, Oregon, and the same value of PORTLAND for Portland,Maine. When you set this option to YES, the two values might become[USA].[Oregon].[Portland] and [USA].[Maine].[Portland], respectively.Note: Depending on the size of the result set, QUALIFY_ROWS=YES can have asignificant, negative impact on performance, because it forces the OLE DB interface tosearch through various schemas to gather the information needed to created uniquequalified names. 4See AlsoFor more information about MDX commands, see “Accessing OLE DB for OLAPData” on page 700.
