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.
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?
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?
I am getting [Error] PLS-00402 (182: 1): PLS-00402: alias required in SELECT list of cursor to avoid duplicate column names error in my SP.I have created alias for each column and still i am getting the error.
for my_rec_lot in
(SELECT LLP.BOOK_VALUE LLP_BOOK_VALUE,LLP.COMMISSION LLP_COMMISSION,LLP.CURRENCY LLP_CURRENCY,LLP.EXCHANGE_RATE LLP_EXCHANGE_RATE,LLP.EXPENSES LLP_EXPENSES,
[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!
I am looking to simplify the below query,
DELETE FROM A WHERE A1 IN (SELECT ID FROM B WHERE BID=0) OR A2 IN (SELECT ID FROM B WHERE BID=0)
Since both the inner queries are same,I want to extract out to a local variable and then use it.
Say,
Array var = SELECT ID FROM B WHERE BID=0;
And then ,
DELETE FROM A WHERE A1 IN (var) OR A2 IN (var)
How to do this using SQLPLUS?
Is there a technique to getting a Top-N query to work as a sub-select in a larger query -or- is there another way to generate Top-N like results that works as a sub-select?
Background:
We have a large query that is being used to build an export from a legacy HR system to a new one. Amount the data needed in the export is the employees primary phone number.
The legacy HR system allows multiple phone numbers to be stored in a simple table structure:
SELECT emp_id, phone_type, phone_number
FROM employee_phones
emp_idphone_typephone_number
------- --------------- -------------------
46021CELL2222222222
46021HOME1111111111
46021WORK3333333333
The new HR system does allow for multiple phone numbers, however they need a primary phone number identified and stored with the employee master information. (Subsequent phone numbers get stored in alternate table.)
From a business perspective, we have decided that if they have a HOME phone in the legacy system that should be the primary in the new system, if no HOME phone, then WORK, if no WORK then CELL.
That can be represented as:
SELECT *
FROM employee_people_phones
WHERE emp_id = '46021'
ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')
emp_idphone_typephone_number
------- --------------- -------------------
46021HOME1111111111
46021WORK2222222222
46021CELL3333333333
Or similarly with Top N concept:
SELECT *
FROM (SELECT *
FROM employee_people_phones
WHERE emp_id = '46021'
ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')) results
WHERE ROWNUM = 1
emp_idphone_typephone_number
------- --------------- -------------------
46021HOME1111111111
Or really what I want in my export:
SELECT phone_number
FROM (SELECT phone_number
FROM employee_people_phones
WHERE emp_id = '46021'
ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')) results
WHERE ROWNUM = 1
phone_number
-------------------
1111111111
However, when the Top-N query is added as a sub-select in a larger query using the employee id from the larger query (WHERE emp_id = export.emp_id), it fails saying that �export.emp_id� is not a valid id.
(SELECT phone_number
FROM (SELECT phone_number
FROM employee_people_phones
WHERE emp_id = export.emp_id
ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')) results
WHERE ROWNUM = 1)
1.Any way around this? Is it possible to put a Top-N (with a WHERE clause using data from the main query) in a sub-select?
2.Any alternatives (other than Top-N) to delivering a ROWNUM=1 result with a �custom� ORDER BY statement?
Other Notes: Yes, we know we could do two queries in the data conversion first deliver the bulk data to the target table, and then update with the phone numbers. However, for multiple reasons, that is less than desirable.
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
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?
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
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

write a query to get the first row after order by clause using single query alone.Example:I can write following query to select first rowselect * from (selec * from t order by col1) where rownum = 1;But here I should not use inline view to get the result. Because my original requirement needs to use this query in select list and it needs to use a column (of a table from the FROM clause) in the where clause of inline query. Because there is restriction that we can not use the column (of a table from the FROM clause) more than one level of inline query.

Can we create a table from a Select query ?
View 5 Replies View RelatedI have a Select query which is not fetching records in 11g (11.2.0.2.0) but working fine in 10g (10.2.0.4.0). The query is as below.

I have a table A on dev with definition as TAble A(address,name) and the same table on Prod is defined as Table A(name,address).
my question is Ihave one package in that am trying to insert into this table as follows:
INSERT INTO A
SELECT b.name name,
a.address address,
[Code]....
so the query works on Prod but fails on Dev because column order is different.
I have 2 solutions:
1. I can mention column names in insert line and modify the query but tomorro some body changes again the definition of table A I need to change the query, so do I have solution in oracle sql that can handle the column order without specifying the column names in insert line.
so tomorrow On prod column order and on Dev column order is different though my sql should successfully execute.
i have a good query but I thought i know the solution but actually I didn't it's very simple and straight forward but i didn't catch the rope terminal to follow now I have the following code
CREATE TABLE TRANSLATORS
(Tr_code VARCHAR2(8),
Tr_name VARCHAR2(50),
Tr_age number(2),
Tr_location varchar2(25),
constraint PK_TR_CODE PRIMARY KEY(Tr_code)
);
[code]....
NOW I NEED A QUERY which will select the only translator who knows the languages written in where clause like if i specify two languages like 'italy' and 'english' the query should retrieve to me GH and SE also if i passed languages 'spainsh' and 'persia' it should return JH only
but if i passed languages like 'Italy' and 'Dutch' it should not return any thing (just : no rows selected)

Specify a correlation name, which is alias for the table, view, materialized view, or subquery for evaluating the query. This alias is required if the select list references any object type attributes or object type methods. link...
i have a problem in the following query. i need to fetch the rows such that i want to fetch all the records keeping "segment1" column as distinct and sum all of the corresponding "quantities" column.

i tried to use the partition technique. using partition solved the problem apperently. the sum function worked but redundancy in "segment1" column still persists. i used the sum function only to extract the distinct "segment1" column and summing its corresponding "quantity" column (only quantity column differs in the redundant rows...)
the second query was like:
SELECT prha.segment1,
prha.creation_date,
SUM(prla.quantity) OVER(PARTITION BY prha.segment1) AS qty,
