Purpose

The Alter Session statement allows you to change various attributes of a connection session.

Syntax

ALTER SESSION SET attribute_name=value

where:

attribute_name
Specifies the name of the attribute to be changed.
value
Refers to the specific value setting for that attribute.

The following table lists session attributes and describes them.

Table 1. Alter Session Attributes
Attribute Name Session Type Description
Current_Schema Database Sets the current schema for the database session. The current schema is the schema used when an identifier in a SQL statement is unqualified. The string value must be the name of a schema visible in the session. For example:
ALTER SESSION SET CURRENT_SCHEMA=eloqua
Ws_Call_Count Remote Resets the Web service call count of a session to the value specified. The value must be zero or a positive integer. Ws_Call_Count represents the total number of Web service calls made to the data store instance for the current session. For example:
ALTER SESSION SET eloqua.WS_CALL_COUNT=0

The current value of Ws_Call_Count can be obtained by referring to the System_Remote_Sessions system table. For example:

SELECT * FROM information_schema.system_remote_sessions 
WHERE session_id = cursessionid()
