I'm using Oracle 11g and I'm trying to set the sequence nextval as default to Primary Key row, when I create the table, Oracle throws an exception that columns are not allowed. Here is an example.
CREATE TABLE EMP (
EMP_ID VARCHAR2(50) PRIMARY KEY DEFAULT MYSECUENCE.NEXTVAL)
I'm trying to create a sequence for a primary key to simply auto-increment by the default of 1. I have a sql script written to generate mt tables, and I'm not sure how to modify the script to include the sequence. I also just want the sequence for a specific column, ie, PK, not the PK in all tables.
Here's a snippet from my script:
create table image
(
image_id int NOT NULL,
source_id int NOT NULL,
CONSTRAINT image_id_pk PRIMARY KEY (image_id),
CONSTRAINT fk_source_id FOREIGN KEY (source_id) REFERENCES source(source_id)
);
Would I add the create sequence statement right after the create table, and if so, how do I apply the sequence to only 1 table and a single column?
Sequence nextval is a pseodocolumn, but where the value of nextval is stored and why before we use CURRVAL for a sequence in our session, we must first initialize the sequence with NEXTVAL?
View 5 Replies View RelatedI am trying to understand the difference between using sequence.NEXTVAL from DUAL as against using it direclty in an INSERT statment.
--Sequence Creation
CREATE SEQUENCE SEQ_ID START WITH 1 MINVALUE 1 NOCYCLE CACHE 500 NOORDER;
--Table1 Creation
Create table TABLEA (COL1 number, COL2 varchar2(10),
constraint COL1_PL primary key (COL1));
--Table2 Creation
Create table TABLEB(COL3 number);
alter table TABLEB add constraint COL1_FK foreign key(COL3) references TABLEA(COL1);
-- Option1 - Using sequence.NEXTVAL from DUAL
DECLARE
v_seq_num NUMBER;
BEGIN
SELECT SEQ_ID.NEXTVAL INTO v_seq_num FROM DUAL;
INSERT INTO TABLEA (COL1, COL2) VALUES (v_seq_num, 'test');
INSERT INTO TABLEB (COL3) VALUES (v_seq_num);
END;
-- Option2 - Using sequence.NEXTVAL in INSERT USING RETURNING INTO clause
DECLARE
v_seq_num NUMBER;
BEGIN
INSERT INTO TABLEA (COL1, COL2) VALUES (SEQ_ID.NEXTVAL, 'test') RETURNING COL1 INTO v_seq_num;
INSERT INTO TABLEB (COL3) VALUES (v_seq_num);
END;
I have a table called table 1 and I am trying to insert a few values in this table and i am constantly getting bogged down by a primary key error. Strange thing is this primary key called "ID" on the table is a system generated sequence value number. The error is
"ORA-00001: unique constraint (Schema1.LICN_PK) violated"
Table structure:
*****************************************
CREATE TABLE schema1.table1
(
ID NUMBER(12),
LITM_ID NUMBER(12),
PROG_PROGRAM_CD VARCHAR2(2 BYTE),
SCHED_NBR VARCHAR2(3 BYTE),
SCHD_VERSION_YR NUMBER(4),
SCHD_VERSION_NBR NUMBER(3),
[code]........
****************Insert statement*************
insert into table1
(id,
litm_id,
prog_program_cd,
sched_nbr,
schd_version_yr,
[code].......
why the error is coming up and any way to resolve it. I checked the max sequence number value and kept running it for a while and then tried to run my insert statement but no luck yet.
I used the following code to create a sequence
create sequence mg_sites_seq
start with 1
increment by 1
maxvalue 10000
cycle
cache 5;
then in my values clause of an insert without a distinct I had mg_sites_seq.nextval as one of my values but I'm getting an error that says it's not allowed there.I also tried to use it as a default value on the create table description (my preference) and got the same message. When I did the create table I commented out the field in the insert and value clause.
I’m trying to avoid a cursor solution and I can’t accomplish this using any group by or aggregate/analytical functions. This approach is basically trying to apply a group by while forcing the group by to operate on the data in a specific order(not the group by order). why is currval giving me the nextval we should get somewhere?
Query:
INSERT INTO WAREHOUSE_DEV.STG_COV_SUBPROGRAM_FUN_CS1 (
CASENUMBER, PREV_CASENUMBER, CLIENT_NUMBER,
PREV_CLIENT_NUMBER, PROGRAMNAME, PREV_PROGRAMNAME,
SUBPROGRAMNAME, PREV_SUBPROGRAMNAME, COVERAGE_YEARMONTH,
CLIENT_COVERAGE, PREV_CLIENT_COVERAGE, CS_COUNT)
select CASENUMBER, PREV_CASENUMBER, CLIENT_NUMBER,
[code]...
The key is that when you have cs_count of 1… get nexval, when you have value of -1 get currval, zero is zero… The first row would get nexval…. So 1 the next seven rows should be 1, then next row 0, the next row 2 and the last 5 rows will also be 2.
Query with currval and nextval:

I want to use default value in pl/sql , i'm executing below code
SET serveroutput ON
DECLARE
l_deptno INTEGER DEFAULT 10;
v_dname VARCHAR2(200);
[Code]...

Enter value for deptno: 40
dname value=OPERATIONS
I tried with NULL to use its default value but it uses NULL(which does make sense)
SQL> @test.sql
Enter value for deptno:

How to use the default value of the passed argument?
expected O/P
dname value=ACCOUNTING
I wanted to know the consequences of adding a DEFAULT value to an existing column in a table.I understand that when you add a DEFAULT value to a column which is Nullable, Oracle updates all the null values for the column to the DEFAULT value, generating a lot of undo/redo data.
Is adding a DEFAULT value to a NOT NULL column a problem? As the column is NOT NULL, an update would not be done, so no undo/redo data will be generated.But will this cause a whole table scan? Is this advisable?

In my point of view, deferral FK (DFK) are stronger than non-deferral FK (NDFK). In other words, every NDFK can be moved to DFK. Is there a performance issue ?

View 5 Replies View RelatedI am trying to find out if there is a definite way to find out (by querying database) which database users have been created by Oracle (either during installation or as part of patching or adding new feature) and which database users have been created by DBAs.
I have looked into the documentation but could not find anything relevant. Ideally, I would like to know if this can be done for any versions starting from 9iR2.
Query that I want to run:
exec DBMS_METADATA.SET_TRANSFORM_PARAM(DBMS_METADATA.SESSION_TRANSFORM,'SEGMENT_ATTRIBUTES', false);
result: E;;45;45 ;45 ;45 ;S 45
I am not sure but may be I need to set long size before running above query. But when I try to set long size gives below error. "The output from DBMS_METADATA.GET_DDL is a LONG datatype. When using SQL*Plus, your output may be truncated by default. Issue the following SQL*Plus command before issuing the

I would like to know the reason why the database is on unencrypted format by default,there must be some reason behind this, i hear from someone that encrypted data degrade performance thats the reasons its on unencrypted format by default.
