ACTUALIZE_ALL

Actualize all objects in the current edition dbms_editions_utilities.actualize_all; PRAGMA SUPPLEMENTAL_LOG_DATA(Actualize_All, AUTO);

exec dbms_editions_utilities.actualize_all;

      

      PL/SQL procedure successfully completed.

CLEAN_UNUSABLE_EDITIONS

Formally drops covered objects in unusable editions, and drops empty unusable editions if possible dbms_editions_utilities.clean_unusable_editions; PRAGMA SUPPLEMENTAL_LOG_DATA(clean_unusable_editions, AUTO);

exec dbms_editions_utilities.clean_unusable_editions;

      

      PL/SQL procedure successfully completed.

COMPARE_EDITION

Compares two given editions to determine their parent/child relation dbms_editions_utilities.compare_edition( ed1objn IN INTEGER, ed2objn IN INTEGER) RETURN INTEGER; PRAGMA SUPPLEMENTAL_LOG_DATA(compare_edition, READ_ONLY);

conn sys@pdbdev as sysdba

      DROP EDITION demo$ed;

SET_EDITIONING_VIEWS_READ_ONLY

Given the table name, set all the Editioning views in all editions to read-only or read write dbms_editions_utilities.set_editioning_views_read_only( table_name IN VARCHAR2, owner IN VARCHAR2 DEFAULT NULL, read_only IN BOOLEAN DEFAULT TRUE); PRAGMA SUPPLEMENTAL_LOG_DATA(set_editioning_views_read_only, AUTO_WITH_COMMIT);

SET_NULL_COLUMN_VALUES_TO_EXPR

Replaces null values in a replacement column with the value of an expression. The expression evaluation cost is deferred to future updates and queries. dbms_editions_utilities.set_null_column_values_to_expr( table_name IN VARCHAR2, column_name IN VARCHAR2, expression IN VARCHAR2); PRAGMA SUPPLEMENTAL_LOG_DATA(set_null_column_values_to_expr, UNSUPPORTED_WITH_COMMIT);
