NULLCHARVAL='character-string'

Details

This option affects insert and update processing and also applies when you use the DBINDEX= and DBKEY= data set options.
It also works with the NULLCHAR= option to determine whether a missing SAS character value is treated as a NULL value. If NULLCHARVAL= is longer than the maximum column width, one of these things happens:
  • The string is truncated if DBFORCE=YES.
  • The operation fails if DBFORCE=NO.
