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.

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.
Enable or Disable All Constraints.

View 7 Replies View RelatedServer Administration :: How To View Table Constraints Information
Mar 13, 2010I know that you can view all constraints in a table using $USER_CONSTRAINTS or $USER_INDEXES view. What i find difficult is that the information in those views is not really well presented.
I find it very hard to follow. For example, just to find out which columns are foreign keys and which tables they refer to is really tedious. Is there a simpler way to view all the constraints especially foreign keys of a table and including which table columns they refer to in the child table.
I like to see a diagramatic representaion of all the tables involved so i like to see both the parent and the child tables, which columns are related and using which FKs etc. is there an easier way to view this information?

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.

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.
