By default, the server
processes the entire table unless the user specifies a range of rows
with the LIBNAME statement options STARTOBS= and ENDOBS=. If the ENDOBS=
LIBNAME statement option is used without the STARTOBS= LIBNAME statement
option, the implied value of STARTOBS=LIBNAME statement option is
1. When both options are used together, the value of the STARTOBS=
LIBNAME statement option must be less than the value of the ENDOBS=
LIBNAME statement option.
In contrast to the
Base SAS software options FIRSTOBS= and OBS=, STARTOBS= and ENDOBS= can be used for
WHERE clause processing in addition to table input operations.
