GS_BLOCKLIST_QUERY

GS_BLOCKLIST_QUERY is used to query job blocklist and exception information. This view is obtained by associating system catalogs GS_BLOCKLIST_QUERY and GS_WLM_SESSION_INFO, and deduplicating query results. If the GS_WLM_SESSION_INFO table is large, the query may take a long time.

  • The schema of the GS_BLOCKLIST_QUERY view is pg_catalog.
  • The GS_BLOCKLIST_QUERY view can be queried only in the postgres database. If it is queried in other databases, an error is reported.
  • Generally, constant values are ignored during unique SQL ID calculation in DML statements. However, constant values cannot be ignored in DDL, DCL, and parameter setting statements. A unique_sql_id may correspond to one or more queries.
