Home -> Community -> Mailing Lists -> Oracle-L -> RE: How to refresh
Here is a sample of the script I run to disable FK constraints:
declare lTables DBMS_SQL.VARCHAR2_TABLE;
lConstraints DBMS_SQL.VARCHAR2_TABLE;
nJ BINARY_INTEGER;
BEGIN
SELECT table_name, constraint_name
BULK COLLECT INTO lTables, lConstraints
FROM user_constraints
WHERE owner = 'IPN_DBA'
AND constraint_type = 'R';
FOR nJ IN 1..lTables.COUNT LOOP
DBMS_OUTPUT.PUT_LINE(lTables(nJ) || ': ' || lConstraints(nJ)); -- just for logging
EXECUTE IMMEDIATE 'ALTER TABLE ' || lTables(nJ) || ' MODIFY
CONSTRAINT ' || lConstraints(nJ) || ' DISABLE';
END LOOP;
END;

Seems like last time I tried to disable constraints Oracle complained and wouldn't let me due to dependant objects or something.

You can always disable triggers and constraints in existing schema before running import (and then, enable them after import is done). Also, specify "CONSTRAINTS=N" and "TRIGGERS=N" when exporting.

I need to do a refresh of a test database using production data. We use import for this. In the past we have always dropped the schemas (4 or 5), recreated the schemas, and then did a full import with ignore=n. This time the user does not want to lose any of the new functions and procedures that are in test, but not in prod. Instead, they would like to just refresh the table data. Last time we tried this we had all kinds of trouble with functions, triggers, constraints, etc... and ended up doing a full import.
Is there a tried and true way to just refresh the table data without losing anything else and without having all the problems with triggers and constraints?
Thanks!
Ron
