SAS/ACCESS Interface to Greenplum 4 Naming Conventions for Greenplum 5473 BL_REJECT_LIMIT=3 BL_REJECT_TYPE=3 BL_USE_PIPE=3 BULKLOAD=ExamplesThis first example shows how you can use a SAS data set, SASFLT.FLT98, to createand load a large Greenplum table, FLIGHTS98.libname sasflt ’SAS-data-library’;libname mydblib greenplm host=iqsvr1 server=iqsrv1_usersdb=users user=iqusr1 password=iqpwd1;proc sql;create table net_air.flights98(bulkload=YES )as select * from sasflt.flt98;quit;This next example shows how you can append the SAS data set, SASFLT.FLT98, tothe existing Greenplum table ALLFLIGHTS. The BL_USE_PIPE=NO option forcesSAS/ACCESS Interface to Greenplum to write data to a flat file, as specified in theBL_DATAFILE= option. Rather than deleting the data file,BL_DELETE_DATAFILE=NO causes the engine to leave it after the load has completed.proc append base=new_air.flights98(BULKLOAD=YESBL_DATAFILE=’/tmp/fltdata.dat’BL_USE_PIPE=NOBL_DELETE_DATAFILE=NO)data=sasflt.flt98;run;Naming Conventions for GreenplumFor general information about this feature, see Chapter 2, “SAS Names and Supportfor DBMS Names,” on page 11.Since SAS 7, most SAS names can be up to 32 characters long. SAS/ACCESSInterface to Greenplum supports table names and column names that contain up to 32characters. If DBMS column names are longer than 32 characters, they are truncatedto 32 characters. If truncating a column name results in identical names, SASgenerates a unique name by replacing the last character with a number. DBMS tablenames must be 32 characters or less because SAS does not truncate a longer name. Ifyou already have a table name that is greater than 32 characters, it is recommendedthat you create a table view.The PRESERVE_COL_NAMES= and PRESERVE_TAB_NAMES= options determinehow SAS/ACCESS Interface to Greenplum handles case sensitivity. (For informationabout these options, see “Overview of the LIBNAME Statement for RelationalDatabases” on page 87.) Greenplum is not case sensitive, so all names default tolowercase.Greenplum objects include tables, views, and columns. They follow these namingconventions.
