+ Description
+
+
+ RESET restores run-time parameters to their
+ default values. RESET is an alternative
+ spelling for
+
+SET configuration_parameter TO DEFAULT
+
+ Refer to for
+ details.
+
+
+
+ The default value is defined as the value that the parameter would
+ have had, if no SET ever been issued for it in the
+ current session. The actual source of this value might be a
+ compiled-in default, the configuration file, command-line options,
+ or per-database or per-user default settings. See for details.
+
+
+
+ See the SET reference page for details on the
+ transaction behavior of RESET.
+
+
+
+ RESET can also be used to release internal resources
+ that are usually released at the end of session. RESET
+ TEMP drops all temporary tables created in the current session.
+ RESET PLANS releases all internally cached plans.
+ RESET SESSION releases all externally visible temporary
+ resources associated with the current session.
