DROP TABLE CON_TEST CASCADE CONSTRAINTS ;
CREATE TABLE CON_TEST (
IDI NUMBER(10,0),
USERID VARCHAR2(10),
PWD VARCHAR2(10),
NOTE VARCHAR(100)
)
----------------------
But i think if table CON_TEST doen't exist, an error message will appear. I know that in SQL Server we can check if table exists or not. So, i wonder if we can do that in Oracle?
By the way, is there any way to run a file script that contents TABLES, STORED, ... on a developed PC connect to oracle db server? (in case, i'm developing on PC, using Net Service Name to conect to Oracle DB Server)
I have a table called TRANS, and a primary key field tran_id. How would i check if there is a record matching tran_id 'DUP7927' ?

i have also another concern as per below xml file.
My requirement is to identify perticular node ,whose having PriorValue attribute present in <pi:the Actual_Comp_Change> tag,those record should return.
<?xml version="1.0" encoding="UTF-8"?>
<pi:Extract_Employees xmlns:pi="urn:com.workday/picof">

1000 roy Intern - Master¿s B 216000
1000 roy Intern - Master¿s 00 266000
But my requirement is to display only those employeeID ,where Actual_Comp_Change tag having PriorValue attribute.
The required OutPUT should be :
EmployeeID_ Name JobTitle_ Grade ActualComp_Change_
1100 Surana Intern - Master¿s A 500000
is there any possibility to use ExistNode() function to the above quer or is there any alternative solution.
1. Below TXN_LOG table Expected to have 0.5 to 1 million records & TXN_LOG_HIST table will have max 3 million records.
2. On daily basis system will move records from TXN_LOG to TXN_LOG_HIST.
3. The below mentioned check will be performed for each transaction, With out this check currently my process is doing 10tps. (transaction per second).
CREATE TABLE TXN_LOG

The below validation we are currently using which is overhead for our transactions processing. Also the below mentioned check will be performed for each transaction, With out this check currently my process is doing 10tps. (transaction per second).
BEGIN
SELECT COUNT(1)

FROMTXN_LOG
WHERE AC_NO = p_acho
TXN_INIT_DATE = p_txn_date

Is there any fastest method to check above record exists validation from the both the table?
How can I create a trigger to check if synonym already exists in db and if exists then don't create synonym.
my work: ( this is just like an outline i prepared)
select * from all_synonyms;
declare
s_exists number;
begin
-- check whether the synonym exists
select 1 into s_exists from all_synonyms;
-- an error gets raise if it doesn't
exception when no_data_found then
-- DDL has to be done inside
execute immediate ' create or replace synonym';
end;

Using a cursor and loop method records are inserted into the header and line tables. How do I code the IF statement prior to the INSert statement such that Insert if record does not exist else Update the record. If the record for insert fails in the line, the same record should be deleted from the header table as well and transaction should rollback. The Ora version used is 11.2.0.2.

View 5 Replies View Related I have a question i wanted to know that " Is it possible to write the Following Query Using NOT EXISTS

And one more doubt is there, can we use join to get same result.

I don't have this file_id, why alert.log is showing me it? Of course, nobody has created this datafile and nobody has removed it too.
following is a query which i find difficult to understand why EXISTS is failing. There are two scenarios where if i block LINE 30 and unblock line 31 of the code then one record is returned.
SELECT A.ENTITY_CODE,
A.VRNO,
A.VRDATE,

Which is the best way to check whether a record exists.

how to write a function that returns top value if not exists then next top for combination of customer_id and hierarchy.For instance :
If I've got table
customer_id ,hierarchy, function_code
123 |1 | Z1
123 |2 |67
123 |3 |5B
678 |10 |S2
678 |11 |Z2
345 |2 |11
For the customer ID 123 I want to return Z1, for customer 678 I want to return S2 and for customer ID 345 I want 11
Problem is that I'm new to the concept of looping. I know how to write a function that accepts customer_id as a value write a cursor and then check IF hierarchy = 1 the return FUNCTION_CODE IF hierarchy - 2 THEN ...
but I need something more universal as some of the customers may have hierarchy function 1 and that would be the top one for him but others might have function of hierarchy 10 as top and checking all of the possibilities using if would be just stupid. So how to write something universal ? And of course if function did not find any customer_id then return null.
I have a list of values from a spreadsheet and want to know which values are NOT matched in columns of a table
here's the list (really 4000+ long)
1234,
2345,
3244,
and I want to find the values that are not in the table 'table_name' like this
....
where not exists (Select number_n from table_name
where number_n in ('1234', '2345', '3244', ...(the list above))
I have this sample:
the column data1 is datetime datatype with
t as ( select 'SMITH' nom,to_date('21/09/2013 07:30:00') data1
from dual union all select 'ALLEN',to_date('21/09/2013 07:40:00')
from dual union all -- select 'WARD',to_date('21/09/2013 07:50:00')
from dual union all
select 'JONES',to_date('21/09/2013 08:00:00')
from dual union all
[Code]..
How can I write a select to check that If I input 10 minutes to nom 'ALLEN' it's ok because the time 07:40 + 10 minutes = 07:50 the row not exists, (the next)but If input 20 it exists because the sum = 08:00 and row isn't free , indeed, there is 'JONES'?
what the difference between IN and EXISTS operator. Why should we use EXISTS operator?
View 1 Replies View RelatedI have a single table with a TOTAL_TIME column which I want to increment by a certain amount every time I get a request from a specific user. If the row for that user does not exist, it should be created and the TOTAL_TIME column should be set to the value that just came in. Otherwise, if it does exist, it should be incremented by the value passed in.
How can I accomplish this in oracle? I don't want to just first do a select, then insert, because that can cause race conditions. I want something that'll do the check and insert/update in one statement (locked).
How to rewrite this query using NOT EXISTS instead of NOT IN
SELECT STUD_ID,
join_date,
stud_nme
FROM code_balance
[code]...
where difference lies between these operators or clause, & whether there is any "except" operator in oracle, i know other three are used bt dont think oracle uses "except" too..as far as i have seen "NOT IN", "MINUS" , "NOT EXISTS" are exactly similar?

View 10 Replies View RelatedI have a basic requirement to report rows from one table where the second table do not have the same record (basically same key).I understand that we could achieve this using not in or not exists clause. But I think using outer join probably be the simplest one. However, I could not achieve what I actually wanted using outer join
Test Case:
create table tab_1 (a number(1), b varchar2(20));
insert into tab_1 values (1,'one');
insert into tab_1 values (2,'two');
insert into tab_1 values (3,'three');
create table tab_2 (a number(1), b varchar2(20));
insert into tab_2 values (1,'one');
insert into tab_2 values (2,'two');
commit;
Now, I framed the query as
select y.a ya, x.a xa, x.b xb
from tab_1 x, tab_2 y
where x.a = y.a (+);
/
YA XA XB
---- ---- ----
1 1 one
2 2 two
3 three
In this case, as there is no corresponding record in second table, the value of YA is showing as null as shown above.Hence, I changed the query as
select y.a ya, x.a xa, x.b xb
from tab_1 x, tab_2 y
where x.a = y.a (+)
and y.a(+) is null;
/
YA XA XB
---- ---- ----
1 one
2 two
3 three
I dont understand why it is behaving in that way. I am rather expecting the output to come as:
YA XA XB
---- ---- ----
3 three
I have 2 queries one which gives me unique records and second which I created using EXISTS to eliminate duplication.i.e. First query gives me 4 records but when I put the table which is in the EXISTS block in the normal join, it gives me 8 records.
But the issue is I want data from the query which I have put in the EXISTS block.
if i have data like this
case 1
code start month end month
winter march march
summer april january
spring feburary feburary
case 2
winter January January
summer february september
spring october december
and if i am trying to enter again start month and end month . i should validate if the month i am giving is already present in the table for any of the season
i want a do the validate with a query so that i will not enter duplicates.
I have the following table with the some sample data:
|| Filename || receiving_site || originating_site ||
| fileA | siteA | HQ |
| fileA | siteA | siteA |
| fileB | siteA | HQ |
| fileA | siteB | HQ |
| fileA | siteB | siteB |
| fileB | siteB | HQ |
| fileB | siteB | siteB |
The table works in such way:
1. For each of the Filename, if originating_site is not the same as receiving_site, it means that the file has been sent to receiving_site but has not been acknowledged received yet.
2. For each of the Filename, if originating_site is the same as receiving_site, it means the file has been sent and received by the receiving_site.
My task is to list out all the Filename per receiving_site that has been sent, but not received yet by the receiving_site. For example from the sample data above, I am expecting to see that siteA, fileB has not been received yet.
How can I do that? I had tried MINUS and NOT EXISTS command, but I am just not able to get the result that I want.
Select query will run fine. But when will run full query (insert + select). we will get below error after 8-10Hrs. No rows insert on table but table is exist.

Problem : print ref cursor gives error (ORA-08103: object no longer exists)/ and message "no rows selected" if ref cursor is based on GTT and commit is called in procedure.

now with commit ;
create or replace procedure p_RB ( p_in in number, c out sys_refcursor)
as

update t1_RB set a = p_in ;
insert into gtt_RB(A) values (1);
[code]....
no rows selected
1/ Once values are selected in ref cursor why it does not shows result set outside ?
2/ Are ref cursors are binded with temp tables ?
3/ if 'YES' is that should be the same case with normal tables ?
4/ Commit is necessary preserve incremental value in t1_rb how we commit with using ref cursors ?
5/ Is it a Bug?

execute statement
SELECT * FROM scott.emp;
