9.1. CURRENT_CONNECTION

Available in

DSQL, PSQL

Syntax

CURRENT_CONNECTION

Type

INTEGER

Description

CURRENT_CONNECTION contains the unique identifier of the current connection.

Examples

select current_connection from rdb$database
execute procedure P_Login(current_connection)

The value of CURRENT_CONNECTION is stored on the database header page and reset to 0 upon restore. Since version 2.1, it is incremented upon every new connection. (In previous versions, it was only incremented if the client read it during a session.) As a result, CURRENT_CONNECTION now indicates the number of connections since the creation — or most recent restoration — of the database.
