* The offset must be the difference between the 2 instances otherwise the import will generate an error: ORA-02291: integrity constraint (APEX_040200.WWV_FLOW_STEP_UI_FK)įROM apex_040200.wwv_flow_user_interfacesĪpex_application_t_offset( l_fui_id_deploy - l_fui_id_source ) To resolve the error, simply rename the object that you are trying. As previously stated, database objects must have unique identifying names. My problem is that despite i put PRAGMA EXCEPTIONINIT this instruction doesn't validate ORA-02291.

As the message suggests, you are trying to create a table, view, index, synonym or other object that has a name that is already in use. Since a foreign key to primary key relationship defines the list of values for a foreign. ORA-00955: name is already used by an existing object. A foreign key means that values in one table must also appear in another table.A references constraint is only applied at SQL ‘insert’ and ‘delete’ times. Foreign Key holds the reference to another table column value.It is also known as references constraint. The offset must be the difference between the 2 instances otherwise the import will generate an error: ORA-02291: integrity constraint (APEX040200.

The following query finds constraints, and displays the table and column that holds constraint with table and column name pointed to by the constraint. Usage Create table statement with foreign key constraint will create table with referential integrity. tapplicationid( lappiddeploy ) If the apex workspaces dont exist in the same DB the query must be executed in the correct one and calculate the offset manually.

In addition the Oracle errors code highlight some further limitations. Somebody asked how to validate foreign key constraints in an Oracle database. SQL> INSERT INTO childtable 2 VALUES (1, DEFAULT) 1 row created. Blog of Dimitri Gielis to share his ideas especially in the Oracle and Oracle Application Express (APEX) domain. * If the apex workspaces don't exist in the same DB the query must be executed in the correct one and calculate the offset manually.
