STATEMENT_COMPLEX_RUNTIME

STATEMENT_COMPLEX_RUNTIME displays load management information about jobs being executed by the current user on the primary database node. The current feature is a lab feature. Contact Huawei technical support before using it.

**Table 1** STATEMENT_COMPLEX_RUNTIME columns
Name	Type	Description
datid	oid	OID of the database that the backend is connected to
dbname	name	Name of the database that the backend is connected to
schemaname	text	Schema name
nodename	text	Database process name
username	name	Username used for connecting to the backend
application_name	text	Name of the application connected to the backend
client_addr	inet	IP address of the client connected to the backend. If this column is null, it indicates either the client is connected via a Unix socket on the server or this is an internal process, such as autovacuum.
client_hostname	text	Host name of the connected client, as reported by a reverse DNS lookup of client_addr. This column will be non-null only for IP connections and only when log_hostname is enabled.
client_port	integer	TCP port number that the client uses for communication with this backend (-1 if a Unix socket is used)
query_band	text	Job type, which is specified by the GUC parameter query_band. The default value is a null string.
pid	bigint	Thread ID of the backend

estimate_total_time	bigint	Estimated execution time of the statement (unit: ms)
estimate_left_time	bigint	Estimated remaining execution time of the statement (unit: ms)
enqueue	text	Resource status in workload management. The current feature is a lab feature. Contact Huawei technical support before using it.

queryid	bigint	Internal query ID used for statement execution
query	text	Statement being executed
