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

The LIBNAME Statement for Relational Databases 4 PRESERVE_TAB_NAMES= LIBNAME Option 169normalization rules do not appear in the output. In SAS line mode, here is how SASindicates the number of tables that do not display from PROC DATASETS because ofthis restriction:Note: "Due to the PRESERVE_TAB_NAMES=NO LIBNAME option setting, 12table(s) have not been displayed." 4You do not get this warning when using SAS Explorer.SAS Explorer displays DBMS table names in capitalized form whenPRESERVE_TAB_NAMES=NO. This is now how the tables are represented in theDBMS.NO is the default for most DBMS interfaces.YESspecifies that table names are read from and passed to the DBMS with specialcharacters, and the exact, case-sensitive spelling of the name is preserved.DetailsFor more information, see the SAS/ACCESS naming topic in the DBMS-specificreference section for your interface in this document.To use table names in your SAS program that are not valid SAS names, use one ofthese techniques.3 Use the PROC SQL option DQUOTE= and place double quotation marks aroundthe table name. The libref must specify PRESERVE_TAB_NAMES=YES. Forexample:libname mydblib oracle user=testuser password=testpasspreserve_tab_names=yes;proc sql dquote=ansi;select * from mydblib."my table";3 Use name literals in the SAS language. The libref must specifyPRESERVE_TAB_NAMES=YES. For example:libname mydblib oracle user=testuser password=testpass preserve_tab_names=yes;proc print data=mydblib.’my table’n;run;To save some time when coding, specify the PRESERVE_NAMES= alias if you planto specify both the PRESERVE_COL_NAMES= and PRESERVE_TAB_NAMES= optionsin your LIBNAME statement.Oracle: Unless you specify PRESERVE_TAB_NAMES=YES, the table name that youenter for SCHEMA= LIBNAME option or for the DBINDEX= data set option isconverted to uppercase.ExampleIf you use PROC DATASETS to read the table names in an Oracle database thatcontains three tables, My_Table, MY_TABLE, and MY TABLE. The results differdepending on the setting of PRESERVE_TAB_NAMES.If the libref specifies PRESERVE_TAB_NAMES=NO, then the PROC DATASETSoutput is one table name, MY_TABLE. This is the only table name that is in Oraclenormalized form (uppercase letters and a valid symbol, the underscore). My_Table doesnot display because it is not in a form that is normalized for Oracle, and MY TABLE isnot displayed because it is not in SAS member normalized form (the embedded space isa nonstandard SAS character).
