SQL & PL/SQL :: Copying Data From Table (with No Constraints) To Table With Constraints?
Jun 13, 2012I want to create a store procedure to copy data from a source tables(which may not have any constraints defined) to a table which has primary key, foreign key and unique key constraints.
Any records which are rejected due to these constraints not being satisfied need to go another table.
Once the initial data load is done, these procedures need to be automated(through cron) to do the future incremental uploads in the same manner.

SQL & PL/SQL :: Trigger Sum Constraints
Mar 7, 2010Basically, I need to fulfil the constraint:
"student cannot have more than 100 points"
I need to use a trigger to do this, but I don't understand how this would work.
Written in plain english I imagine it work work something like:
AFTER UPDATE
WHERE student.lessonid = lesson.lessonid
IF SUM(lesson.points) > 100 then ROLLBACK
lessonid is the only field relating the two tables.
--
How to fulfill that criteria, whether it be using triggers or not.
SQL & PL/SQL :: Constraints On Objects?
Mar 5, 2012Ive created a scenario to what im trying to achieve here so ignore how its set-up attribute wise.
CREATE TYPE object_obj AS OBJECT (
obj_id NUMBER,
NAME VARCHAR2(20),
age NUMBER) NOT FINAL;
/
CREATE TYPE object_ext UNDER object_obj (
course_name VARCHAR2(20));
/
CREATE TYPE object_ext2 UNDER object_obj (
location VARCHAR2(20);
/
CREATE TABLE object_tab OF object_obj(obj_id PRIMARY KEY);
/
Now for the course_name i need to make sure it can only be on of these three values ('Science','Math','English'). I can't find a way to apply this constraint without making a table. But then that creates another issue of how to insert the data from the main supertype (object_obj) and i only want the object_tab table and view the subtypes via a select query.

Remove Constraints On Nested Table?
Jul 11, 2011I want to truncate table partition but I'm getting error:
CODEORA-02266: unique/primary keys in table referenced by enabled foreign keys
because of table has a nested table. Currently this column is not in use so I could drop it, but I want to avoid it (table is huge). Is there another posibility to do truncate partitions in this table? ALTER TABLE ... SET UNUSED doesn't resolve the problem.

Apr 8, 2010I knew, how to enable or disable a constraint on a table.
>alter table <table_name> disable constraint <constraint_name>;
But if we know all the data is correct, it's better to disable all constraints to improve the performance.
We are allowed to Disable or Enable only a single constraint.

May 4, 2013I am doing partitioning in the table ap_invoices_all and i have gone through all the process of i am making a script for a table and process
1. Create the new partitioned table with the same column structure as the original and with the partitions.
2. Insert data from the original table to the partitioned. Use parallel DML.
3. Rename the indexes of the original table
4. Create indexes to the partition table with the same columns as the original indexes.
5. Save the source code of the original table triggers
6. Rename the triggers of the original table to OLD
7. Do the table renaming. Rename original table to OLD and the partitioned table to original.
8. Drop the synonyms for the OLD table and recreate to point to the new partitioned
9. Grant the appropriate privileges to new partitioned table.
10. Create the triggers to the partitioned table
i want to know do i need to copy the constraints of the original table to the partitioned table?
