Using column alias with CASE

It is possible to use a column alias with a CASE in a SELECT? e.g. I have this code
SELECT
CASE WHEN categ_1 = 'BASIC' THEN total_1 WHEN categ_2 = 'BASIC' THEN total_2 END
FROM totalsBut the results column name comes out as CASEWHENCATEG_1='BASIC'THENTOTAL_1WHENCATEG_2='BASIC'THENTOTAL_2END
I want to use an alias but can't get it to work with the CASE. I guessed at
SELECT
CASE WHEN categ_1 = 'BASIC' THEN total_1 WHEN categ_2 = 'BASIC' THEN total_2 END 'alias'
FROM totalswhich doesn't work.

Try without the single quotes after END

Using column alias for calculations in same select list

Hi All,
I want to use a calculated column of query to create further calculated columns in same query using column alias. I have to do so because the calculation is too big to write it everytime.
e.g.
Select decode(Month, 1, Tran_January, 2, Tran_February, ....) as MonthTran,
Month, Year,
round(MonthTran/Intrest_rate, 2) as Amount <---(using previous alias)
from ledger;
Thanks in advance,
Mona

Probably the easiest way of doing this is to write an inline view, viz
SELECT l.Month
 , l.Year
 , round(mt.MonthTran/l.Intrest_rate, 2) AS Amount
FROM ledger l
 , (SELECT x.pk_col, decode(Month, 1, Tran_January, 2, Tran_February, ....) AS MonthTran
 FROM ledger x) mt
WHERE l.pk_colunm = mt.pk_colunm
; If you have any criteria in a WHERE clause on ledger you shouldn't need to repeat them providing LEDGER does have a primary key column. You may need to tweak it a bit for performance, if LEDGER is a big table.

Use column alias in another calculation

Database:Oracle Database 11g Enterprise Edition Release 11.2.0.3.0
Is there a way to use a column alias in an another calculation within the
same query? Since I am using some long and complex logic to compute total1
and total2, I don't want to repeat the same logic to compute the ratio of
those two columns. do you have any suggestion other than nested sub-query or view?
select
total1 = sum(case(long complex logic)),
total2 = sum(case(another long complex logic)),
ratio = total1/total2
thanks in advance

Use oracle's with clause

AS
SELECT sum(case(long complex logic)) total1,
sum(case(another long complex logic)) total2
from your_table_name
SELECT total1/total2

ORA-00904 when use column alias in Record Group Query

Is it possible to use column aliases in Record Group Queries?
I have a query that runs fine in SQL*Developer, but gives me runtime errors when I use it as a Record Group Query.
When I use it as a Record Group Query, the Form compiles, but at runtime I receive the following errors:
FRM-40502: ORACLE error: unable to read list of values
when I use Help - Display Error, I see:
ORA-00904:"CHILDNAME":invalid identifier
The query is something like this
select decode(complex stuff here) as "childname" ....
I've tried it with and without the double quotes surrounding the alias name, and have also tried it without using the "as" keyword.
I would appreciate any suggestions or insights. I'm using Forms 9.0.4.
Thanks.

It looks like this is caused by bug 725059:
"FILTER BEFORE DISPLAY" DOESN'T WORK IF LOV HAS COLUMN ALIASES (TRIAGE1098)
My LOV does have the Filter Before Display turned on. Here's the text of the bug:
IF an LOV is created with column aliases in the select statement, (eg: select ename emp_name from emp) and the LOV property "Filter Before Display" is "Yes", THEN when you attempt to filter the LOV at runtime, (eg: type '%' then press the 'Find' button) the internal WHERE clause that forms sends to the database is: WHERE column_alias LIKE '%%' This is incorrect syntax. A client-side sqlnet trace shows this. The correct syntax should be: WHERE column LIKE '%%' . The incorrect syntax results in no rows returned. However no error is displayed by forms to the user.

I use a yahoo email as my Apple ID. How can I use an alias with no one knowing

How do I know if my daughter is using an alias for her iCloud/Apple id.

Any apple id has ability to create up to three aliases that nobody would know. Purpose of creating more then one alias is to give people different email addresses. Example would be if I had automotive business and computer business, so emails addressed to [email protected] and [email protected] would go to my mail box.
Downside - they all go to the same mail account - which is your first account alias. So if you were to go to icloud.com website and sign in with your [email protected] or [email protected] - you will still see all of those icloud.com emails (not the yahoo ones).
Close enough?

Using directory alias with a wanboot installation

I have setup a Jumpstart server and have been using it for a while without issues. Now I want to incorporate wanboot into the process so that I do not need boot servers in each of our subnets. Since the jumpstart directory structure is already in place and I have apache running on the same server, I did not want to have to recreate the whole jumpstart directory structure. So I decided to create an alias in the apache configuration for the jumpstart directory:
root@swamphenxb:/usr/local/apache2/conf> cat httpd.conf
<snip>
# ScriptAlias: This controls which directories contain server scripts.
# ScriptAliases are essentially the same as Aliases, except that
# documents in the target directory are treated as applications and
# run by the server when requested rather than as documents sent to the
# client. The same rules about trailing "/" apply to ScriptAlias
# directives as to Alias.
Alias /jumpstart /export/jumpstart
ScriptAlias /cgi-bin/ "/usr/local/apache2/cgi-bin/"
</IfModule>
<IfModule cgid_module>
# ScriptSock: On threaded servers, designate the path to the UNIX
# socket used to communicate with the CGI daemon of mod_cgid.
#Scriptsock logs/cgisock
</IfModule>
# "/usr/local/apache2/cgi-bin" should be changed to whatever your ScriptAliased
# CGI directory exists, if you have that configured.
<Directory "/usr/local/apache2/cgi-bin">

I have the client configured to boot from the web server and when I attempt to boot, I get the following message:

It looks like maybe wanboot does not like the alias I am using, but I want to verify that before I move on to plan B. Thanks.

Using URL alias with Weblogic - How do you do it?

Bear with me I have zero experience with Weblogic.
We use Weblogic as a component of Hyperion Planning, meaning for Hyperion Planning weblogic is installed and acts as the java application AND webserver.
Currently our Hyperion Planning URL is http://servername:port as per security audit we need to use an alias so that users do not have straight access to the direct URL link.
Therefore we created on the DNS a URL alias BFS.companyname.com. Now I need to associate this alias with the Planning URL which is in weblogic.
I have logged into the weblogic admin console and see 'Virtual Hosts', I enter in the host name BFS.companyname.com and select the target which is the Hyperion Planning workspace (http://servername:port) apply changes yet nothing occurs.
If anyone has done a URL direction could you please post the instructions on how to do so...thanks
JTS

Just to share this will all. The URL alias redirection is done within Apache webserver and not the Weblogic program.
Edit the httpd.conf file with this information below:
1. Configure Apache to listen on port 80:
a. Back up the configuration file, e:\Hyperion\common\httpServers\Apache\2.0.52\conf\ht tpd.conf
b. Add "Listen 80" to the Listen section.
c. In the Virtual Hosts section, (around line 955), uncomment the line, "NameVirtualHost *:19000"
d. Add "NameVirtualHost *:80"
e. Uncomment the "<VirtualHost *:19000>" code block, down to "</VirtualHost>"
f. Edit and add the following block to Virtual Hosts
<VirtualHost *:80>
ServerName www.myserver.com
DocumentRoot e:/Hyperion/common/httpServers/Apache/2.0.52/htdocs
</VirtualHost>
g. Restart Apache.
2. Redirect Web Page
a. Create a page in the virtual web directory, index.html that contains the following html code:
<html><head>
<meta http-equiv="Refresh" content="0; url=http://myserver:19000/workspace/index.jsp">
</head><body>
</body></html>
b. Have someone in NSE alter or create a DNS entry that redirects "hyperion" to the appropriate IP address. The default page (index.html) on the default port (80) will execute the redirect in the html document above, launching the workspace login screen.

How to use Substring function with Case statement.

Hello Everyone,
I have one requirement where I have to use substring function on the field for report criteria.
E.G.
I have Branch Name Field where I have all branch names information, Now some of the branch names are too big with some extension after the name .
now i want to substing it but the character length varies for each branch.
so is there any way where we can use case statement where we can define that if branch name character are exceeding some value then substing it with this length.

Try something like this:
CASE WHEN LENGTH(tablename.Branch_Name) > n THEN SUBSTRING(...) ELSE tablename.Branch_Name END
where n is the number of characters you want to start the break.

T-SQL - Using Column Name in where condition without any references when having multiple tables that are engaged using multiple joins.

Hi All,
I am a newbie for T-Sql, I came across a SP where multiple tables are engaged using multiple joins but the where clause contain a column field without any table reference and assigned for an incoming variable,like
where 'UserId = @UserId'
instead - no table reference like 'a.UserId = @Userid' ............ Can any please do refer to me any material that clears my mind regarding such issue................... help is appreciated.
Thank You.

As suggested above, use table alias with columns for unique referencing and to make the code easier to read.
BOL example for table aliasing:
USE AdventureWorks;
GO
SELECT S.CustomerID, S.Name AS Store, A.City, SP.Name AS State, CR.Name
AS CountryRegion
FROM Sales.Store AS S
JOIN Sales.CustomerAddress AS CA ON CA.CustomerID = S.CustomerID
JOIN Person.Address AS A ON A.AddressID = CA.AddressID
JOIN Person.StateProvince SP ON
SP.StateProvinceID = A.StateProvinceID
JOIN Person.CountryRegion CR ON
CR.CountryRegionCode = SP.CountryRegionCode
ORDER BY S.CustomerID ;
GO
GO

Check the use of TABLE ALIASes and COLUMN ALIASes in the following blog:
http://www.sqlusa.com/bestpractices2005/organizationtree/
Without the use of aliases the code would become unreadable.

Column alias

Hi,
in oracle express, on a report querry region I give this :
select 'PINS - # of times an item in the library cache was executed - '||
sum(pins),
'RELOADS - # of library cache misses on execution steps - '||
sum (reloads),
'RELOADS / PINS * 100 = '||round((sum(reloads) / sum(pins) *
100),2)||'%'
from v$librarycache
But I receive :
1 error has occurred
query column #1 ('PINS-#OFTIMESANITEMINTHELIBRARYCACHEWASEXECUTED-'||SUM(PINS)) is invalid, use column alias
Any idea ? Any help ?
Many thanks.

You need to define column aliases.
SQL> SELECT 'PINS - # of times an item in the library cache was executed - ' || SUM (pins) AS LibRatio,
2         'RELOADS - # of library cache misses on execution steps - ' || SUM (reloads) AS MissRatio,
3         'RELOADS / PINS * 100 = ' || ROUND ((SUM (reloads) / SUM (pins) * 100), 2) || '%' AS Ratio
4    FROM v$librarycache
5 ;

Issue with Column Alias Name in a SELECT statement

I am trying to run sql query(IN ORACLE) to get the data from a remote database(TERADATA). The query is
select (table1.exp_date - table1.setup_date) AS day_diff,
CASE
WHEN day_diff = '0'
THEN 'YES'
WHEN day_diff > '0'
THEN 'NO'
ELSE 'Unknown'
END AS alias_type
from table1@remote_database_name;
The query is running fine when I run it in TERADATA environment directly without the remote database link since it is not necessary. If I run the above query in Oracle I am getting an error ORA-00904: invalid identifier.(this error is pointing to day_diff alias name)
Can anyone help me with this?
Thanks

The Column alias can be used in the ORDER BY clause, but not other clauses,like WHERE clause, in the query.
Use..
select (table1.exp_date - table1.setup_date) AS day_diff,
CASE
WHEN (table1.exp_date - table1.setup_date) = '0'
THEN 'YES'
WHEN (table1.exp_date - table1.setup_date) > '0'
THEN 'NO'
ELSE 'Unknown'
END AS alias_type

Using SQL alias column names in same SQL

Hi,
I am converting some Teradata SQL queries and these queries have the ability to use column defined aliases within the same query, something like :
SQL> select 'test' as alias1, 'test2' as alias2, alias1 from dual
Does anyone know how I can get Oracle to do this ????
Many thanks
Ben

Hi,
Yes I did think of that - its just the queries calculated columns are quite large - sample below show a value calculated currently based on alias names - just trying to find an easier way to apply.
I was hoping for some magical syntax that has eluded me !
