No Column Names in 'Column Alias' Configuration

I have a column alias action following a transaction call. I'd like to rename the XML columns coming out of the call. A Tracer on the transaction call output shows columns but when I configure the Column Alias action, no columns appear in the drop down lists.
Any ideas?

Never Mind - I didn't have a reference document assigned correctly. It works now.

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

Column alias name

Hi All,
can we use the column alias name in expression in a select query?
example,
select (10+20) as col1, (col1+30) as col2 from dual;
when i execute the above query, i am getting "col1 is invalid identifier".
can please some one answer to my query OR is there any other way to get the answer to my query?

As you found out, you can't do it that way... What you can do is something like
select (col1+30) as col2
from (select 10+20 as col1
from dual
)

Flexible column alias name?

Hi
Is that a way to assign the column alias name at run time.
Example: I want to sums a column and label it based on the current year.
For 2007, I should have:
SELECT
‘A’
‘B’,
‘C’,
sum(RESERVE_AMT) AS RESERVE_AMT_2007
FROM table_name
For 2006 I should have:
SELECT
‘A’
‘B’,
‘C’,
sum(RESERVE_AMT) AS RESERVE_AMT_2006
FROM table_name
For 2005 I should have:
SELECT
‘A’
‘B’,
‘C’,
sum(RESERVE_AMT) AS RESERVE_AMT_2005
FROM table_name
Etc.
For some reason I need a sql (something like above) in the procedure to be run in each year and populate a column labeled the current year concatenated with a fix string such as RESERVE_AMT_2007.
Thanks.

If you don't explicitly specify a name for the output column, Oracle will try to generate one based on the input expression. If the name does not follow the normal rules for identifiers (one of which is that the name can't contain special symbols, like parentheses) then the name must be enclosed in double-quotes.
Notice that these rules are a little different from the rules about result sets. In the result set of a main query, for example, column names do not have to be unique, and a system-generated name like 'SUM(E.SALARY)" is acceptable.
Actually the book hasnt specfied the need for an alias at this place ...so i wanted to know why am getting this error ..I can't see which book you're reading. Post a quote. If the book is available on line, post a link, too.

@Column alias possible?

Hi all
is there a way to define an alias for an entity column?
I'd like to define a named querey in a super class. The 'where clause' of the EJB Query contains a field that has a certain functionality, but is not yet named (as this is the job of the subclass (developer)) - Anyhow, I'd like to prepare the query (cause it's all the same for every subclass) and use a columnname like 'defalutname' for the column I don't yet know the name of.
Later when setting up the subclass entity, I'd define something like this:
@Column( name = ..., ALIAS = "defaultname", ... )
... so the predefined queries would work with that entity.
@Entity
public class ... {
@Column( name = "shortname", ALIAS = "defaultname",
columnDefinition = "varchar(100) default ''",
nullable = false, insertable = true, updatable = true )
public java.lang.String getShortname() { return this.shortname; }
Any ideas how to get this work?
Ty in advance.

Column alias results in ORA-00972

Hi,
I am using Eclipselink v1.0.2 on glassfish.
I have a query where I have set the maxResults to 1 like so:
this.entityManager.createQuery("SELECT t FROM Tbl t where t.name='271040300018**'")
 .setMaxResults(1)
 .getResultList();
The resultant query contains a column alias that has more than 30 characters which causes an ORA-00972 error. I've noticed that if I don't call setMaxResults the query does not contain aliased column names. Is there a way to either make sure that the query generator does not generate invalid column names or get it to not alias columns when I have a result set limit?
Thanks,
Drew
Edited by: user10816727 on Jan 27, 2009 1:02 PM

Here is the generated query with the problematic aliases bolded. Note that I cannot change the length of the non aliased column names as a workaround.

Database column alias problem

When joining the firstname and surname fields in my inital SQL query of my interactive report i.e
INITCAP(INDSNAME)||' '||INITCAP(INDFNAME) AS FULLNAME,
When clicking through to the record detail page I am getting the following error from the page item where in the source I am specifying FULLNAME under Source value or expression
Column FULLNAME not found in table MYTABLENAME
How can I get around this?
Many Thanks

Hi Bas
Thanks - it will just be a view as basically I just want to print the data via jasper
In my IA report under column attributes there is one called FULLNAME which is derived from INITCAP(INDSNAME)||' '||INITCAP(INDFNAME) AS FULLNAME,
So how can I get the data displayed in the FULLNAME column in the IA report into a single record view. At the moment my IA report the Link Column is currently linked to a 'Link to custom target'
the target is a 'Page in this Application' in this case page 9
and in Item1 under Name the value is P9_ROWID and the value is #ROWID#

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

Quotes in a column alias

Possible to have double quotes in a column alias in a SQL projection? Long story involving Apex, Anychart v5 and how Apex names data serie in XML generated for multiple Y axis.
This problem can be easily solved if I can add a double quote into a column alias. E.g.
select
some_col as "COL1"" param1=123"
from dualNo comment about Apex using column labels for generating XML tag name-values... {noformat} ;-) {noformat}
Of course, the SQL parser does not like the above format at all.
Had a look at the SQL Reference guide and it does not say much in this regard. Seems like there's no workaround - correct?

Hi,
I can't think of any way to do that in SQL.
In SQL*Plus, you can use COLUMN ... HEADING, with doubled double-quotes:
COLUMN     dummy     FORMAT     A20     HEADING     "COL1"" param=123"
SELECT     *
FROM     dual;Output:
COL1" param=123

Comma in report column alias breaking PDF Printing?

It appears that some (but not all) special characters (e.g., a comma) in a report column alias causes an error when using PDF printing under "Print Attributes" for reports.
This query works fine:
select sysdate as "Date Today" from dual
But the query below causes the error "Adobe could not open 'report[1].pdf' because it is either not a supported file type or because the file has been damaged...":
select sysdate as "Date, Today" from dual
Does anyone know a work-around? My real alias is "Lastname, Firstname" so I would like to keep the comma!
We're using APEX 3.0.1 and PDF printing with Apache FOP.
Thanks ahead of time.
Cindy

Hi Cindy,
why not use the "Heading" property of a report column to show a speaking column heading? The column alias isn't really intended for that purpose.
Set the "Heading Type" to "Custom" then you are able to change them for each column.

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 ?
