I am a new learner of PL/SQL databases,A kind of exercise given to apply database on apex.oracle.com with given sequence.Then I have created tables but when it comes to fill tables with the insertion code as follows,Application has given error,Would you mind if I need your assistance
Thanks in Advance,
CREATE TYPE TEMPORAL_VARCHAR AS OBJECT (
VALID_TIME_LOWER_BOUND DATE,
VALID_TIME_UPPER_BOUND DATE,
VALUE_PART VARCHAR2(50)
);
CREATE TYPE TEMPORAL_NUMBER AS OBJECT (
VALID_TIME_LOWER_BOUND DATE,
VALID_TIME_UPPER_BOUND DATE,
VALUE_PART NUMBER );
Time-related attributeshave defined with the code as follows;
CREATE TYPE NAME_TYPE AS TABLE OF TEMPORAL_VARCHAR;
CREATE TYPE ADDRESS_TYPE AS TABLE OF TEMPORAL_VARCHAR;
CREATE TYPE DEPARTMENT_TYPE AS TABLE OF TEMPORAL_VARCHAR;
CREATE TYPE MANAGER_TYPE AS TABLE OF TEMPORAL_VARCHAR;
CREATE TYPE SALARY_TYPE AS TABLE OF TEMPORAL_NUMBER;
CREATE TABLE EMPLOYEE (
SSN NUMBER primary key,
NAME NAME_TYPE,
ADDRESS ADDRESS_TYPE ,
BIRTH_DATE DATE,
MANAGER MANAGER_TYPE ,
DEPARTMENT DEPARTMENT_TYPE,
SALARY SALARY_TYPE
)
NESTED TABLE NAME STORE AS NAME_TABLE,
NESTED TABLE ADDRESS STORE AS ADDRESS_TABLE,
NESTED TABLE MANAGER STORE AS MANAGER_TABLE,
NESTED TABLE DEPARTMENT STORE AS DEPARTMENT_TABLE,
NESTED TABLE SALARY STORE AS SALARY_TABLE
;
And the insertion that I am inteded to do
INSERT INTO EMPLOYEE VALUES
(101,
NAME(TEMPORAL_VARCHAR('23.11.2005','12.31.9999','James Brown')),
ADDRESS(TEMPORAL_VARCHAR('23.11.2005','12.31.9999','BUCA, IZMIR')),
'23.10.1986',
MANAGER(TEMPORAL_VARCHAR('23.11.2005','12.31.9999','Mike White')),
DEPARTMENT(TEMPORAL_VARCHAR('23.11.2005','12.31.9999','DEPT_ID05')),
SALARY(TEMPORAL_NUMBER('23.11.2005',’12.31.9999’, 250000))
);
And the error message I recieved is :
ORA-00904: "SALARY": invalid identifier
There are spaces before _ here
CREATE TYPE MANAGER _TYPE AS TABLE OF TEMPORAL_VARCHAR;
CREATE TYPE SALARY _TYPE AS TABLE OF TEMPORAL_NUMBER;
DEPARTMENT DEPARTMENT _TYPE
A comma is missing after DEPARTMENT _TYPE
try this solution:
'alter session set NLS_DATE_FORMAT='DD.MM.YYYY';'
----------------------------------------------------
INSERT INTO EMPLOYEE VALUES
(101,
NAME_TYPE(TEMPORAL_VARCHAR('23.10.1986','09.09.9999','James Brown')),
ADDRESS_TYPE(TEMPORAL_VARCHAR('15.12.2009','09.09.9999','BUCA')),
'23.10.1986',
MANAGER_TYPE(TEMPORAL_VARCHAR('24.05.2008','09.09.9999','Mike White')),
DEPARTMENT_TYPE(TEMPORAL_VARCHAR('03.01.2012','09.09.9999','DEPT_ID05')),
SALARY_TYPE(TEMPORAL_NUMBER('01.01.2003','09.09.9999', 3200))
);

I have created an object type and a table. I would like to know how select, insert, update and delete operation on it.
create table employee_info (
empid number,
emp_name varchar2(50),
department varchar2(20),
designation varchar2(50),
salary number
);
create type employee_info_obj is object (
empid number,
department varchar2(50),
designation varchar2(50),
salary number
);
create type employee_info_obj_t is
table of employee_info_obj ;
You have only created an object type and an unrelated database table. If you want a database table based on the type, you need to create one:
create table employee_info of employee_info_obj;
While it can be nice in certain programming scenarios to have a type synced to a table, there are some downsides such as it being harder to add columns later, and third party tool support since the object table will not be listed in user_tables but only in user_object_tables and user_all_tables, so I would question the usefulness of this approach.

I want to inserted into my collection some SQL records, but I can not. I'm a beginner. Can you help me ?
This is my tables :
CREATE TYPE article_type AS OBJECT (idA CHAR(10), nomA CHAR(10), prixA CHAR(10) )
CREATE TYPE facture_type AS OBJECT (idF CHAR(10), dateFact DATE)
CREATE TYPE ens_collection_fact AS OBJECT (refFact facture_type, refArticle article_type)
CREATE TYPE collection_fact AS TABLE OF ens_collection_fact
CREATE TYPE client_type AS OBJECT (idC NUMBER, nomC CHAR(10),adresse CHAR(10), Compose collection_fact )
CREATE TABLE Article OF article_type
CREATE TABLE Facture OF facture_type
CREATE TABLE Client OF client_type (PRIMARY KEY(idC)) NESTED TABLE Compose STORE AS temp
This is my query that I want to insert, but I have an error from the Oracle : ORA-02315
INSERT INTO ECOLER.CLIENT VALUES
(100, 'Jules Verne', '1', Collection_fact(Ens_collection_fact(reffact('A','2002-12-10'), ens_collection_fact(refarticle('D','E','F'))) ))
Thank in advance
reffact and refarticle are identifiers for objects within other objects, not types; you need to refer to the actual types. You also need to supply both values for each Ens_collection_fact attribute for the default constructor; you can pass null if you only want one or the other:
INSERT INTO CLIENT VALUES
(100, 'Jules Verne', '1',
Collection_fact(
Ens_collection_fact(facture_type('A',date '2002-12-10'), null),
Ens_collection_fact(null, article_type('D','E','F'))
)
)
Also notice that I've added the date keyword so it's providing an actual date literal rather than a string, which would be converted - if you're lucky - with your session NLS settings.
This will still error because 'Jules Verne' is 11 characters and you've defined the name attribute as 10 characters/bytes, but it will work with a shorter string literal.

I am getting data from a feed file which is stored in Oracle Table TYPE.
Table TYPE created:
CREATE OR REPLACE TYPE typ_employee AS OBJECT
(
EMP_NAME DATE,
EMP_DEPT NUMBER,
EMP_SALARY NUMBER,
);
/
How can I find the unique records from this object and insert in another table.
Please help with this query.
You can use nested table and then use SET(Nested_table) which gives you distinct records in the nested table.
Or You can insert data from one table to another using cursor and use exception dup_val_on_index in exception block and you can skip that records (primary key should be added in second table) or update the existing one
I have created two objects T_PERSONS,T_BUSINESS_PERSON where T_BUSINESS PERSON is a subtype and T_PERSONS is a supertype.
---Creating T_PERSONS OBJECT---
CREATE OR REPLACE
TYPE T_PERSONS AS OBJECT
( id integer,
first_name varchar2(10),
last_name varchar2(10),
dob DATE,
phone varchar2(12),
address t_address,
) NOT FINAL;
---Creating T_BUSINESS_PERSON OBJECT---
CREATE TYPE t_business_person UNDER t_persons
(title varchar2(20),
company varchar2(20)
);
Now I created an object table object_customers
CREATE TABLE object_customers OF t_persons
INSERTING DATA INTO object_customers
INSERT INTO object_customers VALUES
(t_persons(1,'Jason','Bond','03-APR-1955','800-555-1211',
t_address('21 New Street','Anytown','CA','12345')
));
in this case,data has been inserted properly
INSERT INTO object_customers VALUES
(t_business_person(2,'Steve','Edwards','03-MAR-1955','800-555-1212',
t_address('1 Market Street','Anytown','VA','12345'),'Manager','XYZ Corp'
));
Now in this case an error has occured
Error-attribute or element value is larger than specified in type.
Please Help.
The second insertion will work only if you create the table as follows:
CREATE TABLE object_customers OF t_business_person;

I have a series of tables and objects I have defined. I have an object nested table that I am trying to insert values into. The values are in the form of a variable array but I don't know how to insert them. my tables and code are as follows.
Table wu.classes
crn number(5)
department varchar2(8)
title carchar2(25)
Table wu.students
student_id char(11)
name varchar2(10)
dept varchar2(8)
advisor varchar(10)
classes wu.classes_va
wu.classes_va varray(5) of number (5)
create type classes_ty as object(crn varchar2(5),department varchar2(8), coursetitle varchar2(25)
create table classes_ot of classes_ty;
insert into classes_ot select crn,department,title from wu.classes;
create or replace type classes_ref_ty as table of ref classes_ty;
create table student_plus(student# varchar2(11),student_name varchar2(10),major varchar2(8), advisor (10), enrolled classes_ref_ty) nested table enrolled store as classes_ref_ty_tab;
Problem here (I need to loop through to fill the table but I just need to know how to do it for one values and i can figure the rest out):
begin
insert into student_plus values('700-123-948','Hooker','CS','VanScoy',classes_ref_ty();
insert into table(select enrolled from student_plus where student#='700-123-948')
select ref(c) from classes_ot c where ???
end;
/
I don't know how to access the variable array and use it with the classes_ref_ty.
