SUMMARY_STATEMENT_COUNT

Displays the summary statistics of five types of statements (SELECT, INSERT, UPDATE, DELETE, and MERGE INTO) and DDL, DML, and DCL statements executed on each database node, as shown in Table 1. In the multi-tenancy scenario, global information is returned if this view is accessed in a non-PDB, and information about a PDB is returned if this view is accessed in the PDB.

**Table 1** SUMMARY_STATEMENT_COUNT columns
Name	Type	Description
user_name	text	Username.
select_count	numeric	Statistical result of the SELECT statement.
update_count	numeric	Statistical result of the UPDATE statement.
insert_count	numeric	Statistical result of the INSERT statement.
delete_count	numeric	Statistical result of the DELETE statement.
mergeinto_count	numeric	Statistical result of the MERGE INTO statement.
ddl_count	numeric	Number of DDL statements. The statistical result contains the SQL statements executed by users and the SQL statements executed by the database backend thread.
dml_count	numeric	Number of DML statements. The statistical result contains the SQL statements executed by users and the SQL statements executed by the database backend thread.
dcl_count	numeric	Number of DCL statements. The statistical result contains the SQL statements executed by users and the SQL statements executed by the database backend thread.
total_select_elapse	numeric	Total response time of SELECT statements (unit: μs).
avg_select_elapse	bigint	Average response time of SELECT statements (unit: μs).
max_select_elapse	bigint	Maximum response time of SELECT statements (unit: μs).
min_select_elapse	bigint	Minimum response time of SELECT statements (unit: μs).

avg_update_elapse	bigint	Average response time of UPDATE statements (unit: μs).
max_update_elapse	bigint	Maximum response time of UPDATE statements (unit: μs).
min_update_elapse	bigint	Minimum response time of UPDATE statements (unit: μs).
total_insert_elapse	numeric	Total response time of INSERT statements (unit: μs).
avg_insert_elapse	bigint	Average response time of INSERT statements (unit: μs).
max_insert_elapse	bigint	Maximum response time of INSERT statements (unit: μs).

avg_delete_elapse	bigint	Average response time of DELETE statements (unit: μs).
max_delete_elapse	bigint	Maximum response time of DELETE statements (unit: μs).
min_delete_elapse	bigint	Minimum response time of DELETE statements (unit: μs).
dbid	oid	ID of the database to which the five types of statements (SELECT, INSERT, UPDATE, DELETE, and MERGE INTO) belong.
user_dml_count	bigint	Number of DML statements executed by users.
bg_dml_count	bigint	Number of DML statements executed by the database backend thread.
