Concat to retrieve column name in select

This is basically what I am trying to do:
SELECT 'LY_'| |to_char(sysdate,'MON')| |'SALES' FROM TERR_ACCT_SUM
Except, instead of returning "LY_OCTSALES", I would like to select the rows in the column LY_OCTSALES. How can I "create" the column name to select?

Not sure if your question was meant using SQL*PLUS or java code.
If you want to use JDBC you could create SQL statements in a String variable and pass it to the executeQuery() method in the Statement object .
If you are using BC4J if you want you could create Dynamic View Objects based on SQL statments created at the run time.

Retrieve column names of a table!!

Hi all,
I want to retrieve column names of a table 'test' whose values are null
For ex:
select * from test
will give the results as
column_1 column_2 column_3 column_4
111
lets consider the case that the table has only one record.
accordingly we have to get column_2 ,column_3 and column_4 as the result.
i tried dynamic 'execute immediate' statement and tried to extract in one single execute immediate statement but i was not able to accomplish because of the multiple columns.
is it possible without using a pl/sql function or procedure??

Check this:
SQL> INSERT INTO my_Test values('ABCD',NULL,NULL);
1 row created.
SQL> COMMIT;
Commit complete.
SQL> select * from my_Test;
COL1       C COL3
ABCD
SQL> declare
2 CURSOR C1 IS SELECT column_name FROM all_tab_cols WHERE table_name = 'MY_TEST';

5 my_cnt NUMBER := 0;
6 BEGIN
7 FOR I in C1 LOOP
8 v_sql := 'SELECT COUNT(*) FROM my_test WHERE '||I.column_name ||' IS NULL';
9 execute immediate v_sql INTO my_cnt;
10 IF (my_cnt > 0) THEN
11 my_null_col_list := my_null_Col_list||','||I.column_name;

Item value as column name in select

Hi,
I have a problem with selecting the columns in the query using items. For example: I have a query:
select column_a from table; or select column_b from table;
and I want to do something like this:
- any item in which I choose the column name
- query: select column_from_item from tale
Is it possible?
My apex version: 4.0.2.00.07
My oracle db version: oracle 11g

Unfortunately, it does not work. For example:
I have a table book (title, themes ...), which is eight rows. When I create a static list of items containing the column names (display name and returns the name) and a report based on select according to your design(select :P5_select from table;), you get eight records in the name of the column.
item: select list -> static list -> display value: Title, return value: Title, name: P1_title
select :P1_title from books;
result which i get:
Title
Title
Title
Title

How to remove column name in select clause

Hello Guys,
I just want to remove a column name in select clause. Because, I don't want to write all column names. I hope I express myself.
In other words, I want the following.
Select   * - unwanted_column from table;
instead of this
Select col1, col2, col3, col4, ........ col 10000 from table;

Hi,
Sorry, there's nothing in SQL that means "all columns *except* ...". As the others have said, the only way to get those results in SQL is to list all the columns you do want.
Your front end may have some feature that allows you to hide a specific column. For example, in SQL*Plus, you can use <tt> COLUMN ... NOPRINT </tt> , like this:
COLUMN      dname     NOPRINT
SELECT       *
FROM       scott.dept
ORDER BY dname
;Output:
`   DEPTNO LOC
        10 NEW YORK
        40 BOSTON
        20 DALLAS
        30 CHICAGOThere is a column called dname in the scott.dept table; the query above actually uses it. But, because of the COLUMN command, SQL*Plus won't display that column.

Using PL/SQL to retrieve column names and column values

If I have a table as follows
Table A(
meal varchar2(32),
beverage varchar2(32),
desert varchar2(32));
and the table contains a row
meal beverage desert
pork chops iced tea apple crisp
Is there a way in pl/sql to retrieve the column names along with the values. I have an object type
DATA_DEFINITION_T AS OBJECT (
          "FIELD_NAME"          VARCHAR2(32),
          "FIELD_VALUE" VARCHAR2(32)
I need to store the column name in field_name and the column value in field_value.
So the result would be:
FIELD_NAME = meal
FIELD_VALUE = pork_chops
FIELD_NAME = beverage
FIELD_VALUE = iced tea
FIELD_NAME = desert
FIELD_VALUE = apple crisp
Thanks in advance.

How to retrieve column names in a query in a case sensitive way

Given a query, I want to extract all the column names/aliases in the query in a case-sensitive way.
When I use dbms_sql.describe_columns() or java.sql.ResultSetMetaData classes getColumnName() or getColumnLabel()
it returns the columns name ONLY in Upper case.
My application needs to extract the column names in the same case as it appears in the query string.
Is there any API to get this without parsing the SQL query string?
Thanks
PS: The dbms_sql.describe_columns() returns the column name in upper case.
declare
IS
l_column_recs DBMS_SQL.DESC_TAB;
l_cur NUMBER;
l_column_count NUMBER;
BEGIN
l_cur := dbms_sql.open_cursor;
dbms_sql.parse(l_cur, 'select target_type from targets', dbms_sql.NATIVE);
dbms_sql.describe_columns(l_cur, l_column_count, l_column_recs);
FOR i IN l_column_recs.FIRST..l_column_recs.LAST
LOOP
dbms_output.put_line(l_column_recs(i).col_name);
end loop;
end;
/

As far as the result set is concerned, though, the column name is in all upper case. If you query the data dictionary, you would see that the TARGET_TYPE column in the TARGETS table is stored in upper case.
The way Oracle works is that column names that are not enclosed in double-quotes are converted to upper case in the data dictionary and elsewhere and then Oracle looks for the column name in the table definition. That is what allows Oracle to have case-insensitive identifiers unless a user specifies case-sensitive identifiers by enclosing the identifier in double quotes.
If you changed the query to be
SELECT target_type as "target_type"
FROM targetsOracle should report the alias in a case sensitive fashion because you've now indicated that the alias should be treated as case sensitive.

Invalid Column Name on select from materialized view?

Hey all, I have created this materialized view for my java to select from. For some reason when I try to select from it, I get invalid column name. Here is my mat view statement in its simplest form:
create materialized view mv_pgridtcevcluster_property as
select distinct clustername_ as "OBJECT_ID", CLUSTERNAME_, LICENSEMODE_
from p_gridtcevcluster p
order by clustername_;
Now when I run my select statement from jdbc:

Anyone have issues with this before? It seems to throw the error sporatically, any help would be much appreciated!

Edited by: TimS on Mar 30, 2009 1:54 PM
Nevermind, figured it out. Was using wrong column name identifier when picking values from resultset.

Since you have "OBJECT_ID" in quotes, Oracle stores the column name literally and case sensitively, and the column name must be capitalized when referenced.
From a regular sql*plus window, try
select object_id from mv_pgridtcevcluster_property;
select OBJECT_ID from mv_pgridtcevcluster_property;
select "OBJECT_ID" from mv_pgridtcevcluster_property;What is the result from each of them?

Dynamic column name with SELECT INTO

I am trying to build a function that derives a pay amount from a set of business rules. There are about 40 columns that hold various pay amounts and their column names are variations of 4 indicators (day shift, vs night shift, etc.) that I have to dynamically look up, ie here is the ID number and a timecard, now figure out which of the 40 fields to look up to get the pay amount.
I can determine from the timecard and employee ID which field to look at, but I'm getting hung up with the syntax needed to construct and execute the statement inside the PL/SQL block. I need to RETURN the pay I extract using the function, and I can create the correct SQL statement, but the EXECUTE IMMEDIATE won't accept the SELECT INTO syntax.
Can someone please suggest a solution? Here is the function:
create or replace FUNCTION FN_GET_PAYRATE(tc in NUMBER, e in NUMBER, pc in VARCHAR2)
RETURN NUMBER
IS
e_id NUMBER;
tc_id NUMBER;

SELECT NVL(PAY_LVL, 1), NVL(PAY_TYPE, 'B'), NVL(RTRIM(EMP_TYPE), 'LHD'), NVL(PROJECT, 001)

END IF;
IF proj <> 001 THEN

--DBMS_OUTPUT.PUT_LINE('RATE COLUMN= ' || var_col);
sql_select := 'SELECT NVL(' || var_col || ', .01) INTO payrt';

sql_and1 := ' AND ACTIVE = 1';
sql_and2 := ' AND JOB_TYPE = ' || CHR(39) || e_typ || CHR(39);

I have alternately tried this:
SELECT NVL(var_col,.01) into payrt
FROM TS_PAYRATES
WHERE PROJECT_ID = proj AND ACTIVE = 1
AND JOB_TYPE = CHR(39) || e_typ || CHR(39)
AND PILE_ID = CHR(39) || pl_cd || CHR(39);
as a substitute for the EXECUTE IMMEDIATE block, but I can't seem to use a dynamic substitution for the column name.
Any help would be greatly appreciated.

That's the most difficult part - the error messages seem to indicate a problem with the SQL statement in its execution context, because I can take the SQL string by itself and it executes perfectly.
Here are three variations:

How to retrieve column name from Excel using POI HSSF eventusermodel?

Passing parameters to table valued functions and using parameters as column name on select

I am creating a function where I want to pass it parameters and then use those parameters in a select statement. When I do that it selects the variable name as a literal not a column. How do I switch that context.
Query:
ALTER FUNCTION [dbo].[ufn_Banner_Orion_Employee_Comparison_parser_v2]
@BANNER_COLUMN AS VARCHAR(MAX),
@ORION_COLUMN AS VARCHAR(MAX)
RETURNS @Banner_Orion_Employee_Comparison TABLE
LAST_NAME nvarchar(max),
EMPNO int,
BannerColumnName nvarchar(max),
BANNER nvarchar(max),
ORION nvarchar(max)
AS
BEGIN
INSERT INTO @Banner_Orion_Employee_Comparison
(LAST_NAME, BANNER, ORION)
SELECT
a.LAST_NAME, @BANNER_COLUMN, @ORION_COLUMN
FROM OPENQUERY(ORCLPROD_APDORACLE, 'select LAST_NAME, BANNER_RANK, BADGE, EMP_STATUS from XTRACT_VIEW') AS a
inner join IWM_Stage.dbo.ViewPersonnel AS b
on a.BADGE = b.badge
WHERE a.EMP_STATUS = 'A'
and a.BANNER_RANK <> b.[rank]
RETURN;
END;
GO
Output
I execute this:
select * from ufn_Banner_Orion_Employee_Comparison_parser_v2 ('a.BANNER_RANK' , 'b.[rank]')
and get:
Cerecerez NULL
NULL a.BANNER_RANK
b.[rank]

George,
You could go for using a CASE statement as earlier mentioned by Erland. This would look like below: (Downside is that you need to be mentioning all possible values in the CASE)
ALTER FUNCTION [dbo].[ufn_Banner_Orion_Employee_Comparison_parser_v2]
@BANNER_COLUMN AS VARCHAR(MAX),
@ORION_COLUMN AS VARCHAR(MAX)
RETURNS @Banner_Orion_Employee_Comparison TABLE
LAST_NAME nvarchar(max),
EMPNO int,
BannerColumnName nvarchar(max),
BANNER nvarchar(max),
ORION nvarchar(max)
AS
BEGIN
INSERT INTO @Banner_Orion_Employee_Comparison(LAST_NAME, BANNER, ORION)
SELECT
a.LAST_NAME
, CASE @BANNER_COLUMN WHEN 'a.BANNER_RANK' THEN a.BANNER_RANK WHEN 'a.BADGE' THEN a.BADGE END --put values as required
, CASE @ORION_COLUMN WHEN 'b.[rank]' THEN b.[rank] END --put values as required
FROM OPENQUERY(ORCLPROD_APDORACLE, 'select LAST_NAME, BANNER_RANK, BADGE, EMP_STATUS from XTRACT_VIEW') AS a
inner join IWM_Stage.dbo.ViewPersonnel AS b
on a.BADGE = b.badge
WHERE a.EMP_STATUS = 'A'
and a.BANNER_RANK <> b.[rank]
RETURN;
END;
GO
Another method that I would suggest is to get all values from the function, then build a dynamic query to obtain results from it .. Something like:
ALTER FUNCTION [dbo].[ufn_Banner_Orion_Employee_Comparison_parser_v2]()
RETURNS @Banner_Orion_Employee_Comparison TABLE
LAST_NAME nvarchar(max),
EMPNO int,
BannerColumnName nvarchar(max),
BANNER nvarchar(max),
ORION nvarchar(max)
AS
BEGIN
INSERT INTO @Banner_Orion_Employee_Comparison(LAST_NAME, BANNER, ORION)
SELECT
* --Returns all the columns
FROM OPENQUERY(ORCLPROD_APDORACLE, 'select LAST_NAME, BANNER_RANK, BADGE, EMP_STATUS from XTRACT_VIEW') AS a
inner join IWM_Stage.dbo.ViewPersonnel AS b
on a.BADGE = b.badge
WHERE a.EMP_STATUS = 'A'
and a.BANNER_RANK <> b.[rank]
RETURN;
END;
GO
--Execution
DECLARE @BANNER_COLUMN AS VARCHAR(MAX), @ORION_COLUMN AS VARCHAR(MAX),@SQL NVARCHAR(MAX)
SET @BANNER_COLUMN='BANNER_RANK'
SET @ORION_COLUMN='[rank]'
SET @SQL='
select LAST_NAME,'+@BANNER_COLUMN+','+@ORION_COLUMN+' from ufn_Banner_Orion_Employee_Comparison_parser_v2 ()'
PRINT @SQL
EXEC @SQL
You just need to make sure that the column names returned by the function are UNIQUE (Using proper alias names) so that you don't have a problem referring to them from the outside..
Thanks,
Jay

Retrieving Column Names from a Query

I need to be able to generate XML that looks like this:
<Categories>
<Category Name='Arrivals'/>
<Category Name='Departures'/>
<Category Name='Unused'/>
<Category Name='Out of Commission'/>
</Categories>
Where the name attribute value is the name of columns in a query. For example, a standard SQL query might look something like this:
select
year, arrivals, departures, unused, out_of_commission
from
some_table
I am able to generate the XML that represents the data just fine. However, my vended application is requiring this column header information. I've browsed and searched the XMLDB documentation but could not see a way to retrive the column names returned by the query. I think I Just need to be pointed in the right direction.
Thanks,
Steve

What technique are you itending using to generate the XML ?.
Does something like this work
select xmlelement("Categories",
xmlelement("Category", xmlattributes('Arrivals' as "Name"), Arrivals),
xmlelement("Category", xmlattributes('Departures' as "Name"), Departures),
xmlelement("Category", xmlattributes('Unused' as "Name"), Unsused),
xmlelement("Category", xmlattributes('Out Of Commission' as "Name"), Out_of_Commission)
from some_table

Cannot use alias for dynamic column name in SELECT statement

Hi,
I want to retrieve values from several tables by using dynamic column & table name as below:
DATA: tbl_name(30) TYPE c VALUE '/bic/tbi_srcsys', " staticly initialized for this example
col_name(30) TYPE c VALUE '/bic/bi_srcsys'. " staticly initialized for this example
SELECT (col_name) INTO CORRESPONDING FIELDS OF TABLE it_values FROM (tbl_name).
The internal table "it_values" does not contain a field named "/bic/bi_srcsys", instead it has another generic field "value" so that the above code can be applied to other tables. I tried to use alias (AS) as below:
SELECT (col_name) AS value INTO CORRESPONDING FIELDS OF TABLE it_values FROM (tbl_name).
But this cannot work. I know that there are other ways to solve this problem, such as by using a single field in SELECT .. ENDSELECT and subsequently appending it to the work area and internal table as below:
SELECT (col_name) INTO (lv_value) FROM (tbl_name).
wa_value-value = lv_value.
APPEND wa_value TO it_values.
ENDSELECT.
Just wonder if there is any other more elegant workaround, because I might have several other fields instead of only one?
Thanks.

Hi Suhas,
thanks for the quick reply.
Sorry that I have not well described the structure of the internal table "it_values". This internal table contains several other fields (key, type, value, etc.).
I guess that the following code
SELECT (col_name) INTO TABLE it_values FROM (tbl_name).
works if the internal table only has one field (value) or the field "value" is in the first position, right?
In this case, I need to fill the "value" field of internal table it_values (ignore the other fields like type, key) with values retrieved from (col_name) of the DDIC table.
Looking forward to your reply.
BR,
Joon Meng

Selecting from a SQL Server 2005 with long column names ( 30 chars)

Hi,
I was able to set up a db link from Oracle 11.2.0.1 to SQL Server 2005 using DG4ODBC.
My problem is that some column names in the Sql Server are longer than 30 chars and trying to select them gives me the ORA-00972: identifier is too long error.
If I omit these columns the select succeeds.
I know I can create a view in the sql server and query it instead of the original table, but I was wondering if there's a way to overcome it with sql.
My select looks like this:
select "good_column_name" from sometable@sqlserver_dblink -- this works
select "good_column_name","very_long_column_name>30 chars" from sometable@sqlserver_dblink -- ORA-00972Thanks

I tried creating a view with shorter column names but selecting from the view still returns an error.
create view v_Boards as (select [9650_BoardId] as BoardId, [9651_BoardType] as BoardType, [9652_HardwareVendor] as
HardwareVendor, [9653_BoardVersion] as BoardVersion, [9654_BoardName] as BoardName, [9655_BoardDescription] as BoardDescription,
[9656_SlotNumber] as SlotNumber, [9670_SegmentId] as SegmentId, [MasterID] as MasterID, [9657_BoardHostName] as BoardHostName,
[9658_BoardManagementUsername] as BoardManagementUsername, [9659_BoardManagementPassword] as BoardManagementPassword,
[9660_BoardManagementVirtualAddress] as BoardManagementVirtualAddress, [9661_BoardManagementTelnetLoginPrompt] as
MANAGEMENTTELNETLOGINPROMPT, [9662_BoardManagementTelnetPasswordPrompt] as MANAGEMENTTELNETPASSPROMPT,
[9663_BoardManagementTelnetCommandPrompt] as MANAGEMENTTELNETCOMMANDPROMPT FROM Boards)performing a select * from this view in sqlserver works and show the short column names
this is the error i'm getting for performing a select * from v_boards@sqlserver_dblink
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Microsoft][SQL Native Client][SQL Server]Invalid column name 'BoardManagementTelnetLoginProm'. {42S22,NativeErr = 207}[Microsoft]
[SQL Native Client][SQL Server]Invalid column name 'BoardManagementTelnetPasswordP'. {42S22,NativeErr = 207}[Microsoft][SQL Native
Client][SQL Server]Invalid column name 'BoardManagementTelnetCommandPr'. {42S22,NativeErr = 207}[Microsoft][SQL Native Client][SQL
Server]Statement(s) could not be prepared. {42000,NativeErr = 8180}
ORA-02063: preceding 2 lines from sqlserver_dblinkI also tried replacing the * with specific column names but it fails on the columns that have a long name (it doesn't recognize the short names from the view)
what am I doing wrong?
