i am working in scott's schema and i want to create foreign key on new table that is "test" table ,structure is----
create table test(id number, name varchar2(20),dno number,pno number);
and now create a foreign key on id column of "test" table reffering the empno of "emp" table which has pk already. but it shows an error-------"ora-ORA-00054-resource busy and acquire with NOWAIT specified or timeout expired"
while i have create the "test" table just 1 min ago.
I have a table where I want user to fill in unique values for a field which is easy to do.
Problem is sometimes the values can be null so an ordinary unique constraint does not work because multiple null records. Is there a way of validating only non null values to ensure all data entered that is non null is unique?
i want to get table name, constraint name, constraint type with join processes in string type. this is what i want: alter table tablename add constraint constraintname constrainttype(columnname)

I want to know constraint name of a particular table if it exists.Here are the queries that i tried to find the constraint name of a particular table but the results were 'no rows selected'.
Queries:
select constraint_name from user_cons_columns where table_name='x'; select constraint_name from user_constraints where table_name='x';
I'm trying to create a new table which has a date field (date of birth) and I want to include a constraint which will not allow me to add values if they are over 21 years old. I'm using SQLPlus .
Can we modifying the existing constraint on table?I have table level UNIQUE constraint on 3 columns of table.I need to modify the UNIQUE constraint to 2 columns? Instead of dropping/recreating the constraint, is there any option to modify the existing constraint
Ex
CREATE TABLE TEST_CONST(NUM1 NUMBER , NUM2 NUMBER , NUM3 NUMBER , UNIQUE (NUM1 ,NUM2,NUM3)); ;
SELECT * FROM USER_CONS_COLUMNS UCC WHERE UCC.TABLE_NAME LIKE 'TEST_CONST';
ALTER TABLE TEST_CONST MODIFY CONSTRAINT SYS_C0025132 UNIQUE(NUM1,NUM2);
There was one constraint define on the column of table that the value of column should be in range of 100 to 200. Some one has deleted the constraint. Is it possible to get the exact name of constraint from any system table.
I use Oracle 10.0.2.0.1.If I create a table with constraint key; after that I create an unique index key, I got an error. Does it mean when I create a table with constraint the unique index are automatically created and I could not create index key as I did as below?
create table test_const(ename varchar2(50) not null, key_num number not null, descr varchar2(100), constraint constraint_test_const unique (ename, key_num)); create unique index test_const_idx on test_const ( "ENAME","KEY_NUM" ) tablespace tmp_data;

I have a table as below. This table is not partitioned.
create table t1 ( d1 date, n1 number not null );
[Code]....
I took an export dump of the above table and after that I renamed the table t1 to t1_old. Then I recreated the table as below with a default constraint on d1 field.
create table t1 ( d1 date default to_date('01/01/1100','DD/MM/YYYY','NLS_CALENDAR=GREGORIAN'), n1 number not null
[Code]....
But the problem here is the data import is taking too much time than what I expected. I can't afford a maxvalue partition here as of my DBA team mentioned if you add maxvalue partition adding partition later in a stage is difficult on this table
apply in this scenario and make the import faster. I am using oracle 10.2.0.1.0 version.
I am a junior DBA. I want to check how many columns are under PRIMARY KEY constraint.
I used dba_constraints view. Please find below details.

I have created a table below, my TL asked me to create a local unique constraint for the below table.
I went through all sites and could not find the correct solution, how to create LOCAL UNIQUE CONSTRAINT ON SUB PARTITION TABLE and LOCAL UNIQUE INDEX ON PARTITION TABLE. Creating Local Unique constraint should take care of creating local unique index creation.
Unique key columns are DET,GDS,ARRIVE_DT
CREATE TABLE SUB_PAR_TAB ( ID VARCHAR2(100) NOT NULL, REGION VARCHAR2(40) NOT NULL, SOURCE VARCHAR2(80) NOT NULL, DET VARCHAR2(80) NOT NULL, GDS VARCHAR2(40) NOT NULL, ARRIVE_DTDATE, SYS_SOURCE VARCHAR2(25) , [code]........
i'm new to oracle environment.how can i specify NONCLUSTERD INDEX on Primary cloumn during table creation.By default it will create clusterd index but i need non-clusterd index on it.
I'm using following stmt to create normal primary constarint during table creation,
CONSTRAINT PKFORM_PROPS PRIMARY KEY (FORM_PROPS_PK) USING INDEX TABLESPACE DB123_INDEX
how can i change the above query, so that it should create NONCLUSTERED INDEX on Primary key column.
creating an sql script that can update info from one table in dbase1 to another table in dbase2 that has the same columns and if possible insert date and time in one column when the synchronized is done?
I am creating a table from another existing table in another schema. The existing table contains data. When I am using the query- create table m _voucher as select * from ipm.m_voucher,I am getting the whole data of m_voucher but I want empty m_voucher table, so what will be the query to get the empty m_voucher table?
Having trouble creating a trigger to populate another table.
The SQL:
CREATE OR REPLACE TRIGGER "P_M_YES" AFTER INSERT OR UPDATE ON DOMAIN REFERENCING NEW AS NEW.P_M AND OLD AS OLD.P_M FOR EACH ROW WHEN (NEW.P_M = YES) BEGIN INSERT INTO PAGE_MAKER VALUES(:NEW.D_NAME, :NEW.USER_ID); END P_M_YES;
I'm creating a stored procedure where i get to return (OUT parameter) a cursor that points to a custom table. If I create an object, I could just do something like:
Quote: CREATE OR REPLACE TYPE TmpObjType AS OBJECT (...); CREATE OR REPLACE TYPE TmpObjTblType AS TABLE OF TmpObjType; PROCEDURE tmp_proc (..., out_param_resultset OUT g_cursor_type ) .... OPEN out_param_resultset FOR SELECT * FROM TABLE(CAST(tmpObjTbl AS TmpObjTblType)); ....
How do I return the table (referenced by a cursor) without creating objects?
I am trying to create a csv file with summarized data. We have a huge table with claim details that is constantly being updated. I am pulling a subset of records that match my criteria into a tempory table (not technically an Oracle temporary table, a regular table that will only exist until I drop it when I am done). This table has multiple entries per claim with different effective dates, paid dates and amounts paid. The result file needs to have one entry per claim with the oldest effective and paid dates and the total of all of the amounts paid on that claim.
Originally I was doing create table new_table as select claim_nbr,other data...,min(ymdeff),min(ymdpaid),sum(amtpay) from my_table group by claim_nbr,other data...
If I ran a select sum(amtpay) from my_table and select sum(amtpay) from new_table I was not getting the same results... If I ran select count (*) from (select distinct claim_nbr from my_table) and select count (*) from (select distinct claim_nbr from new_table) or select count (*) from new_table I was getting the same number of rows. So I wasn't completely losing claims from one table to the next, just some of the details. So, I tried running this:
select * from (select claim_nbr,sum(amtpay) paysum from my_table group by claim_nbr order by claim_nbr) m, (select claim_nbr,sum(amtpay) paysum from new_table group by claim_nbr order by claim_nbr) n where m.claim_nbr = n.claim_nbr and m.paysum <> n.paysum;
It came back with the claim number causing the issue. I looked at all the entries in my_table for that claim and every field was identical except the ymdeff, ymdpaid and amtpay. There were 4 records in my_table however the amtpay in new_table was only a sum of 2 of the records... I our admin look over my shoulder to see what was wrong and they wanted me to recreate new_table. So I dropped new_table and ran the exact same SQL to recreate the table. The number of distinct claim numbers was still the same in both tables and the sum of new_table was off but not by the same amount. I ran my comparison to see which claim was off and now there were two claims where the totals didn't match and neither were the same as the claim that was wrong that first time. We dropped new_table and recreated it several times and every time we got different results... No one else knows the name of my_table so no one was messing with it at the same time plus the sum of amtpay in my_table always comes back the same.
Our admin said he thought he remembered there being something "funny" with the min function sometime so he had me remove those fields. Ran the query several times and the total came out correct each time. Well I still need the dates so I came up with another way (very convoluted) using subqueries and ranking. It seemed to work at first then it started losing random numbers of claims (fewer rows in new_table than distinct claims in my_table) or keeping all the claims but dropping detail lines like I had using the min functions.
Here is the backwards way around using min that drops whole claims sometimes but works fine other times:
CREATE table new_table as (select claim_nbr,other data...,amtpay,ymdeff,ymdpaid from (select claim_nbr,other data... ,sum(amtpay) amtpay from my_table group by claim_nbr,other data...
While creating external table how can I specify a particular decode condition for a date field that comes in as '2099-99-99' i want to change it to '2099-01-0001', how i can translate it
