The Dbmsinfo Function—Retrieve Information on Current Session

Dbmsinfo is a function that returns a string containing information about the current session. This statement can be used in the Terminal Monitor or in an embedded OpenSQL application.

The dbmsinfo statement has the following syntax:

SELECT DBMSINFO ('request_name') [AS result_column]

For example, to determine which version of the Enterprise Access product or server you are using, enter:

select dbmsinfo('_version');

In OpenSQL, only one dbmsinfo request is allowed per SELECT statement. In addition, when issuing a SELECT DBMSINFO statement, you cannot specify other SELECT statement clauses (such as FROM or WHERE).

The following table lists valid request_names:

Request Name	Response Description
autocommit_state	Returns 1 if autocommit is on; 0 if autocommit is off.
_bintim	Returns the current time and date in an internal format, represented as the number of seconds since January 1, 1970 00:00:00 GMT.
database	Returns the name of the database to which the session is connected.
dba	Returns the DBMS username of the database owner.
_et_sec	Returns the elapsed time for session, in seconds.
query_language	Returns query language in use (“SQL”).
server_class	Returns the class of DBMS server, for example “db2”.
terminal	Returns the terminal address for local connections.
transaction_state	Returns 1 if presently in a transaction, 0 if not.
unicode_normalization	Returns blank if the database does not support Unicode or does not perform normalization. Returns NFC if the database supports the NFC normalization form. Returns NFD if the database supports the NFD normalization form.
username	Returns the DBMS user name of the current session's user (like user).
_version	Returns the DBMS version number.
