UPDATE_ISOLATION_LEVEL=DBMS-specific-value

- dbms-specific-value

See the documentation for your SAS/ACCESS
interface for the values for your DBMS.
The degree of isolation identifies the degree to which:
-
the rows that are read and updated by the current application
are available to other concurrently executing applications
-
update activity of other concurrently executing application processes
can affect the current application.
See the SAS/ACCESS documentation
for your DBMS for additional, DBMS-specific details about locking.
To
assign this option to a group of relational DBMS tables
or views, see the UPDATE_ISOLATION_LEVEL= LIBNAME Option.
