GS_MATVIEW_DEPENDENCY

GS_MATVIEW_DEPENDENCY provides association information about each incremental materialized view, base table, and Mlog table in the database. The Mlog table corresponding to the base table does not exist in the full materialized view. Therefore, no record is written into the Mlog table.

**Table 1** GS_MATVIEW_DEPENDENCY columns
Name	Type	Description
oid	oid	Row identifier (hidden attribute, which must be specified).
matviewid	oid	OID of a materialized view.
relid	oid	OID of a base table of a materialized view.
mlogid	oid	OID of a Mlog table which is the log table of a materialized view. Each Mlog table corresponds to one base table.
