SQL & PL/SQL :: Copying Data From Table (with No Constraints) To Table With Constraints?

Jun 13, 2012

I 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, 2011

I 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.

SQL & PL/SQL :: How To Disable Or Enable All Constraints In A Table

Apr 8, 2010

I 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.

Server Administration :: How To View Table Constraints Information

Mar 13, 2010

I 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?

Constraints - Cannot Enter Multiple Lines Of Data?

Apr 8, 2008

I have some tables (below), but I'm having trouble entering multiple lines of data.Here are the tables I have created.

Quote: CUSTOMER table
SQL> create table customer
2 (customer_no char(6) not null,
3 name varchar2(30) not null,
4 address varchar2(50) not null,
5 credit_limit number(6,2),
6 constraint customer_customer_no_pk primary key (customer_no));

Table created.
SALESMAN table
SQL> create table salesman
2 (salesman_id char(8),
3 name varchar2(20) not null,
4 address varchar2(50) not null,
5 emaill_address varchar2(30),
6 constraint salesman_salesman_id_pk primary key (salesman_id));

Table created.
ITEM table
SQL> create table item
2 (ISBN char(13) not null,
3 title varchar2(30) not null,
4 price number(4,2) not null,
5 constraint item_ISBN_pk primary key (ISBN));

Table created.
INVOICE table
SQL> create table invoice
2 (invoice_no char(1) not null,
3 invoice_date date not null,
4 salesman_id char(8),

[code]...

Table created.
DELIVERY table
SQL> create table delivery
2 (invoice_no char(1) not null,
3 ISBN char(13) not null,

[code]...

Table created. I can enter data into the customer, salesman and item table without any problems. However, I need to enter multiple lines of data using the same invoice_no (which is 1). The data is generally the same, except for 2 things need changing but I keep getting the following error...

Quote: ORA-00001: unique constraint(SYSTEM.INVOICE_INVOICE_NO_PK) violated

I understand that I can only use invoice_no once since it is a unique key.

SQL & PL/SQL :: Trigger Sum Constraints

Mar 7, 2010

Basically, 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, 2012

Ive 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.
