Updated at: Sep 17, 2021 GMT+08:00

This section describes parameters related to the connection mode between the client and server.


Parameter description: Specifies the name of the client program connecting to the database.


Value range: a string

Default value: gsql


Parameter description: Specifies the database connection information, including the driver type, driver version, driver deployment path, and process owner. (This is an O&M parameter. Do not configure it by yourself.)


Value range: a string

Default value: an empty string

  • An empty string indicates that the driver connected to the database does not support automatic setting of the connection_info parameter or the parameter is not set by users in applications.
  • The following is an example of the concatenated value of connection_info:
    {"driver_name":"ODBC","driver_version": "(GaussDB 8.1.1 build af002019) compiled at 2020-01-10 05:43:20 commit 6995 last mr 11566 debug","driver_path":"/usr/local/lib/","os_user":"omm"}

    driver_name and driver_version are displayed by default. Whether driver_path and os_user are displayed is determined by users.
