REFRESH_DEPENDENT v18

Use the REFRESH_DEPENDENT procedure to refresh all material views that depend on the views specified in the call to the procedure. You can specify a comma-separated list or provide the view names in a table of DBMS_UTILITY.UNCL_ARRAY values.

Use the first form of the procedure to refresh all material views that depend on the views specified in a comma-separated list:

REFRESH_DEPENDENT(
  <number_of_failures> OUT BINARY_INTEGER,
  <list> IN VARCHAR2,
  <method> IN VARCHAR2 DEFAULT NULL,
  <rollback_seg> IN VARCHAR2 DEFAULT NULL
  <refresh_after_errors> IN BOOLEAN DEFAULT FALSE,
  <atomic_refresh> IN BOOLEAN DEFAULT TRUE,
  <nested> IN BOOLEAN DEFAULT FALSE);

Use the second form of the procedure to refresh all material views that depend on the views specified in a table of DBMS_UTILITY.UNCL_ARRAY values:

REFRESH_DEPENDENT(
  <number_of_failures> OUT BINARY_INTEGER,
  <tab> IN DBMS_UTILITY.UNCL_ARRAY,
  <method> IN VARCHAR2 DEFAULT NULL,
  <rollback_seg> IN VARCHAR2 DEFAULT NULL,
  <refresh_after_errors> IN BOOLEAN DEFAULT FALSE,
  <atomic_refresh> IN BOOLEAN DEFAULT TRUE,
  <nested> IN BOOLEAN DEFAULT FALSE);

Parameters

number_of_failures

number_of_failures is a BINARY_INTEGER that contains the number of failures that occurred during the refresh operation.

list

list is a VARCHAR2 value that specifies the name of a materialized view or a comma-separated list of materialized view names. The names can be schema-qualified.

tab

tab is a table of DBMS_UTILITY.UNCL_ARRAY values that specify the names of a materialized view.

method

method is a VARCHAR2 value that specifies the refresh method to apply to the specified views. The only supported method is C, which performs a complete refresh of the view.

rollback_seg

rollback_seg is accepted for compatibility and ignored. The default is NULL.

refresh_after_errors

refresh_after_errors is accepted for compatibility and ignored. The default is FALSE.

atomic_refresh

atomic_refresh is accepted for compatibility and ignored. The default is TRUE.

nested

nested is accepted for compatibility and ignored. The default is FALSE.

Examples

This example performs a complete refresh on all materialized views that depend on a materialized view named emp_view that resides in the public schema:

DECLARE
  errors INTEGER;
BEGIN
  DBMS_MVIEW.REFRESH_DEPENDENT(errors, list => 'public.emp_view', method =>
'C');
END;

Upon completion, errors contains the number of failures.
