358 PRESERVE_COL_NAMES= Data Set Option 4 Chapter 11See AlsoTo assign this option to a group of relational DBMS tables or views, see the“PARTITION_KEY= LIBNAME Option” on page 164.“DIMENSION= Data Set Option” on page 322PRESERVE_COL_NAMES= Data Set OptionPreserves spaces, special characters, and case sensitivity in DBMS column names when youcreate DBMS tables.Alias: PRESERVE_NAMES= (see “Details”)Default value: LIBNAME settingValid in: DATA and PROC steps (when creating DBMS tables using SAS/ACCESSsoftware).DBMS support: Aster nCluster, DB2 under UNIX and PC Hosts, DB2 under z/OS,Greenplum, Informix, Microsoft SQL Server, MySQL, Netezza, ODBC, OLE DB, Oracle,Sybase IQ, TeradataSyntaxPRESERVE_COL_NAMES=YES | NOSyntax DescriptionNOspecifies that column names that are used in DBMS table creation are derived fromSAS variable names by using the SAS variable name normalization rules. (For moreinformation see the VALIDVARNAME= system option.) However, the databaseapplies its DBMS-specific normalization rules to the SAS variable names when itcreates the DBMS column names.The use of name literals to create column names that use database keywords orspecial symbols other than the underscore character might be illegal when DBMSnormalization rules are applied. To include nonstandard SAS symbols or databasekeywords, specify PRESERVE_COL_NAMES=YES.YESspecifies that column names that are used in table creation are passed to the DBMSwith special characters and the exact, case-sensitive spelling of the name preserved.DetailsThis option applies only when you use SAS/ACCESS to create a new DBMS table.When you create a table, you assign the column names by using one of these methods:3 To control the case of the DBMS column names, specify variables with the desiredcase and set PRESERVE_COL_NAMES=YES. If you use special symbols orblanks, you must set VALIDVARNAME=ANY and use name literals.
