Is there any way through which we can put forth a condition on Alias name instead of column name in a table.
For example: Select emp_name "Employee Name" fom dual where emp_id is not null;
Instead can there be a workaround so I can put "Employee Name" in where clause?
I have Oracle loaded on a server. I have three database instances - /db1, /db2, /db3. I want to put the database in backup mode before I take a backup copy of the three database instances.
Is the database put in backup mode just once and then the three instances can be backed up? Or does each instance need its own script to put the database in backup mode?
When I run the code below It runs very Long. It updates SUSR5 in the TEMPTABLE3 that has 112000 records. If I Change it when c>m to 2 to test. It runs very fast. The value for m is always between 10000 and 12000. That How many times it must loop to update the correct records.

I have 2 tables, ASSIGNMENT and RESEARCH_PAPER. For each research paper, I need to find out :
1. The number of assignments created from it (after a given constant assign date)
2. The number of assignments created from it that have been approved.
3. The number of unique users who have either created or approved an assignment from it
Test data :
create table research_paper (id int, name varchar2(100));
create table assignment (id int, r_paper_id int, assigner_id int, assignee_id int,
approver_id int, assign_date timestamp, approved_yn varchar2(10));
insert into research_paper values (1, 'A');
insert into research_paper values (2, 'B');
[code]....
Assignment :
id r_paper_id assigner_id assignee_id approver_id assign_date approved_yn
-----------------------------------------------------------------------------------------------------------
11 100 200 100 23-10-12 12:00:00.000000000 AMY
22 200 100 200 22-10-12 12:00:00.000000000 AMN
32 100 200 101 24-10-12 12:00:00.000000000 AMY
[code]....
Research_paper:
id name
----------
1A
2B
Expected result :
r_paper_id created approved unique_users
-----------------------------------------------
1 3 2 4
2 3 2 3
I wrote the following query for that :
SELECT rp.id r_paper_id,
COUNT(*) created,
COUNT(
CASE
WHEN a.approved_yn = 'Y'
[code]....
But it fails, saying that 'single-row subquery returns more than one row' when I introduce the 'unique_users' clause. The remaining fields of the output are correct.
I am having a application which is on Widows NT Operating system.I am using Oracle 10g Database, Developer suite 10g And 10g Application server.
My application uses Run_report_object to generate reports.Run_Report_Object is called in forms and Report server is configured in the same Application server where FMX are placed.
The report generation was working fine as long as oracle default login was used. When i created a form to handle login on my own, Report server is throwing "Unable to connect to database" error. My login forms takes the parameters from user and calls default logon command in on_Logon trigger.
I want to select all the field from the table and want to put alias for only field i m just wondering is there any way to write a query something like
select *, emp as employee
from empMaster
here i want to display all the column but only with emp column i want to put alias.
why this query works fine:
SELECT Z.ZAJEZD_ID, Z.JMENO,
(
SELECT COUNT(ZAJEZD_ID)
FROM trasa T
WHERE T.ZAJEZD_ID = Z.ZAJEZD_ID
) AS POCET_ZASTAVEK
FROM zajezd Z
ORDER BY Z.JMENO
But when I try to use the alias to filter the results like this (note the WHERE part):
SELECT Z.ZAJEZD_ID, Z.JMENO,
(
SELECT COUNT(ZAJEZD_ID)
FROM trasa T
WHERE T.ZAJEZD_ID = Z.ZAJEZD_ID
) AS POCET_ZASTAVEK
[code]...
Then it throws an error message ORA-00904: Unknown Identifier for the column/alias POCET_ZASTAVEK?
I have the following query:
SELECT AGENCY, COUNT(*)
FROM (SELECT A.AGENCY,SUM(A.NUM_LOGIN)
FROM GOVAGENCY A
WHERE AGENCY = 'DOD1'
GROUP BY A.AGENCY
[code].......
The results are:
AGECNY COUNT(*)
-------- -----------
DOD1 1
DOD2 1
2
The rollup value has a blank label instead I want to have a label to the rollup result also ex:
AGENCY COUNT(*)
--------- -----------
DOD1 1
DOD2 1
DEPT. OF DEFENSE 2
I have a need to use the Alias name of a column within the same select statement( because I can't have another select statement using the first select as table - BO tool limitation).
Ex:
Select dept_id, agency, sum(quantity) as "sum_qty"
where sum_qty > 500;
Currently oracle won't allow using alias name Sum_qty in the same select statement. Is there a way to use alias within the same select statement?
Is it possible to substring an alias field?
I am looking to substring the following so that the age comes back as 2 digits rather than an indefinite number
months_between (c.fatt,b.birth_dt)/12 age
In my Oracle 9i Schema, I have two tables:
Table One
pocOne pocTwo
2 3
2 4
1 2
Table Two
TableTwoId Name
1 Jones
2 Smith
3 Edwards
4 Camden
My SQL to fetch all records with Smith works great:
select Name from TableTwo
Inner Join TableOne
on TableTwo.TableTwoId in (TableOne.pocOne, TableOne.pocTwo)
where Name = 'Smith'
Now I need to create an alias for the Name field. Here is my attempt:
select myAliasName from TableTwo
Inner Join TableOne
on TableTwo.TableTwoId in (TableOne.pocOne, TableOne.pocTwo),
(select Name as myAliasName from TableTwo)
where myAliasName = 'Smith'
This attempt pulls up all the records instead of just Smith records. How I can create an alias for the Name field in my above query?
My OTN account handle shows the number but till yesterday it was showing the Alias Name "ranit B".

We have a query which uses start by and connect with method. this query works fine in our earlier version 10. But when we migrated to 11g, we are facing problem with the query.
Scenario 1:
------------
There is a table in Schema 1 and created a view for the same.
Table : create table alias_test1 ( A varchar2(10),B varchar(10),C varchar2(20),D varchar2(40), E varchar2(10),F number(1));
View: create or replace view alias_vw1
as select A, B,C,D, E,F from alias_test1
Values :
Insert into A.ALIAS_TEST1 (A, B, C, D, E, F)
Values ('Block1', '136', 'TOTBANK', 'Total Bank', ' ', 1);
Insert into A.ALIAS_TEST1 (A, B, C, D, E, F)
Values ('Block2', '136', 'PPRSEGHKB', 'HKB', 'TOTBANK', 2);
Now in the schema B, created a synonym for the view to access. create synonym alias_vw1 for alias_vw1@link.world
Query :
select srl_no,cde,pdesc,lvl,is_leaf,hcy
from( select srl_no,
cde, pdesc, level lvl,
connect_by_isleaf is_leaf,
Ltrim(replace(sys_connect_by_path (rpad(Trim(cde),19,' '),'~'),'~',' ')) hcy
[code]...
In a query can we have the same alias for more than 1 table as in the following example
Select C.ContractNum, B.Billnum, B.Billamt,A.
From Contractmaster C,
Billdetails B,
Address A,
Currencymaster c,
Where B.billtype = 1
and C.Contractnum = B.Contractnum
and C.customerref = A.Customerref
and c.currencycode ='EUR'
In the above query, Table Contractmaster has an alias C --in capitals while table Currencymaster has an alias c - in small caps ...
Is this possible in Oracle 11g ? Also i found that the table Currencymaster has no Join conditions I executed the query, without any errors!

During a duplicate process to a new database name, rman crashed after the restore but before the switch datafile all.So now, we have under ASM the data files under the correct (new) diskgroup but v$datafile contains the previous names (and so diskgroup) and v$datafile_header is empty. RMAN is completly lost, our solution is to manually rename each file under SQL*Plus using ALTER DATABASE RENAME FILE. Unfortunately, we are using or migrating to OMF, so file names are meaningless and we are unable to associate ASM files with database files.
Any way (query or anything else) to associate the ASM files to the database files. Here's an abstract of what we have for one (small) tablespace:

View 6 Replies View RelatedI have EMPLOYEE table that have 3 records with EMP_ID 1, 2, 3. Now I want to run below query
select emp_id from employee where emp_id in (1, 2, 3, 4, 5);
It will return only 3 records but i want those records also which is not available in employee table. Is this possible without using another table or creating another table. Actually I don't have enough privileges to create table.
& want output like below
EMP_ID
1

4 Not Found
5 Not Found
Here emp_id 4, 5 is not available in employee table, but query should return those value also with comments like "Not Found"
I need to check somewhere in the code as " Check the variable with in 20 varaiables , if not excute somes statements"

v1=150;
if( v1<>a1 AND V1<> a2 AND V1 <> a3...... AND V1<>20)
execute some insert block;
End if;
But it's writting very diffcult as i need to compare with 20 varaiables.Was there any alternative sloution like taking some VARRAY and checking in IF condition like v1 NOT IN(Va) (Where 'Va' is like VARRAY)

When we execute the 1 query above it should not show 1 and 2 records...as i am using NOT IN condition.
I had a procedure in which there will be multiple update and select statements Eg: Update table T1 set Column1='X' where Column2 in ('A','B','C') All the update/select queries will have same set of values in the in condition ('A','B','C') will remain same. But the tables and columns will vary.So, I would like to declare a variable/array which holds the values in the in condition
var1 := {'A','B','C'}
and use in my statement like :-
Update table T1 set Column1='X' where Column2 in var1. Is there any way to acheive this?
I would like to use REGEXP_LIKE condition expression with '[:alnum:]' operator in Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 for to check the string is alphanumeric or not.Why do i need: I have xinput field [RAW(24)] which not sure to contains always an alphanumeric string. We should use only when xinput field is an alphanumeric string.
x varchar2(50);
x:=rtrim(ltrim(utl_raw.cast_to_varchar2(xinput)));
how should i use REGEXP_LIKE
select 'TRUE' from dual where REGEXP_LIKE( 'True', '[:alnum:]')
select 'TRUE' from dual where REGEXP_LIKE( 'False%*^tt123.***', '[:alnum:]')
I'm passing some parameters from java code to a query as follows:
select * from table1
where col1 = 'yes'
--want to make this part dynamic
*$[variable]*
where the $[variable] = 'and col2 like ''some%'' and col3 = ''good'''
So this query is giving me an error saying that it cannot construct such query because i guess what it's trying to run is:
select * from table1
where col1 = 'yes'
*'and col2 like ''some%'' and col3 = ''good'''*
I need to remove the first and last single quote... I tried using double quote for my string and replace all single quotes with empty but the "LIKE" function only works with single quotes (like 'some%')..
I also tried using:
select * from table1
where col1 = 'yes'
and trim (both '''' from 'col2 like ''some%'' and col3 = ''good''')
but i get a "ORA-00920: invalid relational operator"...
How oracle retrieves data from a table.like let say a table product as

table product dont have any index on it
now if this table conatain 500 rows and we have two query
1. select * from product where id=26
2. select * from product
does both query take same time or first query will execute in less time since it has where condition

I have a query with order by clause, which takes 30 sec to execute with order by clause. And if i remove the order by clause it executes within 1 sec.
The column in the order by condition has index. but when i see Explain plan output. it doesn't show this index is being used. I tried to execute query with INDEX hint but still explain plan is not showing this index.
