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.
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.
After creating all the tables and the constraints, and inputting data to the table.. i want to delete everything. i try using drop table but it doesn't get rid of the constraints.
So I'm here creating some tables and if theres a guide where I can take a look at some Constraints Declarations , Mostly cause i have some values on the table that cannot be negative so i need to set constraints to be positive
why my code wont work. Am trying to create a constraint so that the only data that can be entered into the size field is a number between 4 and 15.
CREATE TABLE accommodation (chalet_no NUMBER (3) PRIMARY KEY, chalet_name VARCHAR2(20) NOT NULL, size NUMBER CHECK (size >3) AND CHECK (size <16), priceperweek NUMBER (4,2) NOT NULL);
When we create a duplicate table, we use the below query:
create table table2 as select * from table1;
But table2 is created without any constraints inherited from table1.Can I know how can i create the table with all the constraints existing in parent table.
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.
can a table level check constraints have conditional checking (if else clause or case conditional structures) and checks which are limited through something like a where clause which inside the table level check constraints.And can a table level check constraints refer to a column in another table column which should have a the same value.
i am a beginner in SQL and want to create a table with the following constraints :
'orderno' should be primary key and start with o 'clientno' should be foreign key 'ordr date' is not null 'salesmanno' foreign key 'delytype' default value 'f' and possible value ( f or p) 'delydate' cannot be less than order date 'orderstatus' values ('in process.......)
here's my
create table sales_order(orderno varchar2(6) like 'o%' primary key, clientno varchar2(6) foreign key references client_master(clientno),deldate date not null,dellyaddr varchar2(25),salesmanno varchar2(6) foreign key references salesman_master(salesmanno), delytype char(1) default 'f',billyn char(1),delydate date check > orderdate,orderstatus varchar2(10)check ('in process','fullfilled','cancelled');
I want to delete data from say 100 tables without disable the constraints.
Tables having foreign key.. which is giving error if I select table randomly to delete.
I want to know the query which will give me the sequence of all tables based upon dependencies, so that If i delete the data on that sequence, it wont give me child record exists error.
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...
the trigger works very well but when i add some trigger between drop and create constraints then first step drop constraint sucessfully but 2nd trigger when create new constraints not working examples of trigger are as under:-
declare s_number varchar2(7); cursor masters is select voc_type,voc_date,voc_no from account.voc_masterorder by voc_type,voc_date,voc_no; abc masters%rowtype; cursor detail is select voc_no,ref_no from account.voc_detail group by voc_no,ref_no; [code]....
