Otherwise, they are treated as the NULLCHARVAL=value.YESindicates that missing character values in SAS data sets are treated as NULL valuesif the DBMS allows NULLs. Otherwise, an error is returned.NOindicates that missing character values in SAS data sets are treated as theNULLCHARVAL= value (regardless of whether the DBMS allows NULLs for thecolumn).DetailsThis option affects insert and update processing and also applies when you use theDBINDEX= and DBKEY= data set options.This option works with the NULLCHARVAL= data set option, which determineswhat is inserted when NULL values are not allowed.All missing SAS numeric values (represented in SAS as ’.’) are treated by the DBMSas NULLs.
