Using Define Statement as Column Name Alias

Hi,
Is it possible to assign a defined variable as a column name in a simple select statement?
For examples -
DEFINE test_case = to_date('01-Jan-2011','DD-Mon-YYYY');
SELECT banana &&test_case
FROM dual;
Which would result in -
01-Jan-2011
banana
Is this at all possible? The column names will change when the date changes so I do not want to just label the columns normally as this would need to be changed every time the script is run for a different month.

Cameron wrote:
DEFINE test = to_char(SYSDATE,'Mon')
SELECT hello &&test
FROM dual
So should that result in -
June
hello
Becuase all I get is a fail and -
15:34:37 ORA-00923: FROM keyword not found where expectedClearly you missed sybrands response.
DEFINE is a SQL*Plus command (SQL*Plus is a GUI tool)
to_char and SYSDATE are SQL functions (SQL is a language)
You cannot use SQL directly in SQL*Plus commands like DEFINE.

How to use INSERT with no column name specified?

I want to insert rows into a database table using JDBC's PreparedStatement. I want to specify all values for each row, so that in plain SQL I would not have to specify column names. I wonder if I can do same thing with JDBC in the same manner (it would save a lot of network traffic as far as I can understand)? The problem is:
I need to know the data types of the columns to use correct setXXX method on my PreparedStatement. For example: ps.setString() for CHAR data and ps.setBytes() for binary data. I can use Connection.getMetadata().getColumns(..,..,tableName,'%') to get column types for all columns in my table as a ResultSet. However but I am not sure if I get them in the right order, i.e. in the order in which the columns have been defined for the table in CREATE TABLE.
So it seems I have a tough choice: to get type information in order externally or to specify (and probably transfer via network) column names in each INSERT statement. :-(
Do I have a better choice? Any ideas will be highly appreciated..

...if I get them in the right order, ....Only reason for that is if you are using a meta-data type solution. If you are then there is no solution. After all customer name and address are both just text. How could you tell which is first even if you had a way to handle the types?
But if your inserts are fixed then try using varchars (single ticked entries.) This depends on the database/driver. If is supported then you will have to use SimpleDateFormat to format dates/times in the correct format for the database or use a prepared statement with bind variables.

Changing the Column names / alias

Hi,
I have an oracle query and it works fine.
select q.sname,
SUM( decode(p.nprofile1,10,1,0)) as "0 - 5",
SUM( decode(p.nprofile1,9,1,0)) as "6 - 10",
SUM( decode(p.nprofile1,8,1,0)) as "11 - 15",
SUM( decode(p.nprofile1,7,1,0)) as "16 - 19",
SUM( decode(p.nprofile1,6,1,0)) as "20 - 20",
SUM( decode(p.nprofile1,5,1,0)) as "21 - 27",
SUM( decode(p.nprofile1,4,1,0)) as "28 - 30",
SUM( decode(p.nprofile1,3,1,0)) as "31 - 40",
SUM( decode(p.nprofile1,2,1,0)) as "41 - 45",
SUM( decode(p.nprofile1,1,1,0)) "46 - Over",
COUNT(q.sname) "TOTAL"
from task_core@cds t, cor_queue q, profile_core@crb p
where t.nmboxid = q.nmboxid
and p.ncodaid = t.nobjectid
and p.ntype=2
GROUP BY q.sname
ORDER BY q.sname
It generates a Cross-tab sort of result and I am using the decode function to generate the result.
My problem is that right now I am using hardcoded column names or alias for the columns generated by the decode function. eg. "0-5", "6-10" etc.
I have another table which contains these values ("0-5","6-10"). I would like to know instead of hard coding the column names like
SUM( decode(p.nprofile1,10,1,0)) as "0 - 5"
can we retrieve the values from the Other table that contains the values "0-5","6-10" etc and display it there in the decode function?
Pls help me with this issue
Thanks

hi,
the column names are always fixed. You can try dynamic sql in pl/sql or spool then execute, but in pure sql, it is not possible

Data load component - add new column name alias

Apex 4.2.2.
Using the data load wizard a list of column and column name aliases had been created.
When looking at the component (shared components/Data load tables/column name aliases) it is possible to edit and delete a column alias there. Unfortunatly it does not seem possible to add a new alias. Do I overlook something, or is there a workaround for this?

Try this:
REPORT ztest LINE-SIZE 80 MESSAGE-ID 00.
DATA: name_int TYPE TABLE OF v_usr_name WITH HEADER LINE.
DATA: BEGIN OF it_bkpf OCCURS 0.
        INCLUDE STRUCTURE bkpf.
DATA:   username LIKE v_usr_name-name_text,
      END   OF it_bkpf.
SELECT * FROM bkpf INTO TABLE it_bkpf UP TO 1000 ROWS.
LOOP AT it_bkpf.
name_int-bname = it_bkpf-usnam.
APPEND name_int.
ENDLOOP.
SORT name_int BY bname.
DELETE ADJACENT DUPLICATES FROM name_int.
LOOP AT it_bkpf.
READ TABLE name_int WITH KEY
    bname = it_bkpf-usnam
    BINARY SEARCH.
IF name_int-name_text IS INITIAL.
    SELECT SINGLE name_text
      FROM v_usr_name
      INTO name_int-name_text
      WHERE bname = it_bkpf-usnam.
    MODIFY name_int index sy-tabix.
ENDIF.
it_bkpf-username = name_int-name_text.
MODIFY it_bkpf.
ENDLOOP.

Execute immediate with using clause to pass column name dynamically

Hai,
Is there any way using execute immeidate to pass the column name dynamically. I used to pass the column value as dynamic with the help of "Using clause" . But if i use to pass column name, it is giving numberic error at run time. Eg,. for testing has been given below.
1. Column value as dynamic, which is working correctly.
create or replace function testexeimm (acctnum char)
return number as
acctbal number;
begin
execute immediate 'select balance from acct_master where acct_no=:a' into acctbal using acctnum;
return acctbal;
end;
2. Column name as dynamic which is not working
create or replace function testexeimm (colnam char)
return char as
acctbal char;
begin
execute immediate 'select :a from ch_acct_mast where rownum=1' into acctbal using colnam;
return acctbal;
end;
Any help in this regard will be highly appericated.
Regards
Sridhar

So the variable has to be numeric too:
create or replace function testexeimm (colnam char)
return number as
acctbal number;
begin
execute immediate 'select '|||colnam||' from ch_acct_mast where rownum=1' into acctbal;
return acctbal;
end;Max

How to use string as a column name

Hello,
I have a fn getField() that returns a column delimited string - amt1,amt2 . I want to use this string as the column name in a second query on table MASTER_AMT and get the values for amt1 and amt2...so when i try....
select getField( 'NPC_NOYTG' ) FROM MASTER_AMT
WHERE ACTI_CODE = 'NPOR';
the o/p i get is...
GETFIELD('NPC_NOYTG')
AMT1,AMT2,AMT3
instead of...
AMT1 AMT2
500 0
that i require.
Any ideas on how to convert the string returned to a column name?
Thanks very much
rgds

Try this ....
In SQL*PLUS
SQL> var ref_c refcursor
--- Then type the follwing at SQL prompt
declare
cursor cur is
select column_name
from user_tab_columns a,
     (select upper(getField( 'NPC_NOYTG')) fld FROM MASTER_AMT
     WHERE ACTI_CODE = 'NPOR') col_lst
WHERE
instr(chr(44) || col_lst.fld || chr(44),chr(44) || a.COLUMN_NAME || chr(44) ) > 0
AND table_name = 'MASTER_AMT';
v_str varchar2(1000):= ' ';
begin
for c in cur loop
v_str := v_str || c.column_name || ',' ;
end loop;
v_str := substr(v_str,1,len(v_str)-1);
open :ref_c for
'select ' || v_str || ' from master_amt';
end;
--- after executing the above block, type the following at SQL prompt
SQL > print ref_c
Please let me know if this works for you. This should for any number of columns returned by the function.

How to use a value as column name in Triggers?

Hello All!!!!!
How can i use a column value instead of field name in triggers? e.g. table X has one column and having following data.

Any solution?

Substitution string used in custom Report column name does not display in PDF version of report

I am using Apex 4.2.6.00.03, Apex Listener 2 via Glassfish4 and have set up all my applications and reports on this system. We previously used Oracle 10.2, with Apache with a custom fopping document.
My issue is that I have a report that has custom column headings using a substitution string to pull in the begin or end date for the report. When the report is run and displayed, the column headings appropriately display the date. However, when I try to set up the Print to PDF option, the column headings are not displaying correctly.
Is it possible to use a substitution string in the column heading? I am able to use the substitution string in the Page Header and Page Footer and those display correctly.
In the Report Attributes setup I have set the "Strip HTML" to Yes and I have four columns that are using the &"ITEM NAME". string. See below for actual display:
The report column headings in APEX displays correctly (bold is the substitution detail):
Fund Account Description Balance 07/01/2014 Budget/Goal FY 14-15 YTD Actual 02/28/2015 Ending Balance 02/28/2015
In the Print Attributes setup, when I get to the Report Columns section, the Heading column displays the headings as set up in the Report Attributes custom and I am not able to edit these names. See below:
In the version of the report that is Printed to PDF I get the following for display:
Fund Account Description Balance %26amp;P347_BEGIN_DATE. Budget/Goal %26amp;P347_FY. YTD Actual %26amp;P347_END_DATE. Ending Balance %26amp;P347_END_DATE.
Any assistance would be greatly appreciated.
Thanks,
Pat

First, the misspelled word is a test object and not data.
Second, all data display correctly.
Third, text object is displaying the old misspelled word.
Fourth, I have eliminated the possibility that problems in of my pdf export routine cause this issue by exporting directly from Crystal Reports Viewer. I print the report to the crystal report viewer. The report looks good. The text object is spelled correctly. Then I click the Crystal Reports viewer's export button in the left upper corner and I export to both EXCEL and PDF. The excel export looks good. The pdf export is misspelled. All the export occurs internally in Crystal reports.
Fifth, I found outthat all users who have this problem have the ADOBE PDF writer installed. I am just suspicious that ADOBE writer is interferring with Crystal export
Sixth, I cannot recreate this problem on any of our development and test machines. It only happens on end-user laptops.
Seventh, I changed the name of the report that had this problem and created a new version and installed on end-user laptop. The behaviour still persists. User saved the report as both RPT and PDF. RPT export looks good. PDF version has the spelling problem. Data on both reports is up-to-date and good. I copied the same RPT export to my PC and exported it to PDF, the pdf looks good. That is why I think something on the end-users laptops is causing the export to use some cached template.
One more thing I did was to change the report name in VB.NET project, recreated a new package and installed on end-user's laptop. The same exact problem is still there.
I have worked with Crystal Reports more than 15 years and I have never such a weird behaviour before. I know this sounds very weird. We are all baffled by what is happening.

How to use get column name.vi in SQL toolkit 2.0?

Due to the vi "get column name.vi" paremeters,no table name has connected to the vi. So, I want to ask how to use this vi for gain one column name of a table. Maybe there are some other ways to solve column name getting.
Thanks.

Thanks!
Error 4101 Description:
Execute SQL - The connection, statement, or query handle you provided is not valid.
I don't just used the toolkit in a while,now, I am developing a irrigation system. For the table field names defined by users,column names must be known before any select operations. Do you have any other good idea about drawing out the columnname parameters?
As you know, a valid DSN and table have been also available. The database I used is Access. The bad thing to me is that there is no any text information gotten. And I think, it may be some problems in connection way which I don't find out.
Really appreciated by your reply.
Could you give me some example in the aspect?
Thank you again.

How to pass column name in slect statement in query

Create a user parameter (say P_field), and assign a valid field name as initial value (say NAME), And In the Query, write
SELECT CODE, &P_field FN_FIELD FROM <table_name> WHERE <condition>And in the BEFORE PARAMETER FORM Trigger under the Report Triggers, write,

Transpose Distinct Date and Use as Column name

All,
I am trying to transpose a distinct date and use it as a column name and list the data below it. My version of Oracle does not have the pivot function. Plus I am having trouble with figuring out how to alter the table name to the distinct date. Can someone provide me with logic that will dynamically take the current format (see below) and transpose it to the needed format (see below)?
Current format:
WEEK_END_DATE     RD     STORE_NUMBER     RANK
09-19-2009     R0011     00505     6

09-26-2009     R0068     03920     1
nth date
The format I need:

Using select list value as column name in SQL

Folks,
Thanks in advance for any help with this
I have a select list with two values (Instance and Username) created by
STATIC2:Username;USERNAME,Instance;INSTANCE
I am trying to pass the value of this (:P2_SELECT) and use it as a column name in a SQL query as below
select USERNAME,
INSTANCE
from table_name
where :P2_SELECT like '%'||:P2_TEXTSEARCH||'%'
When I substitue the :P2_SELECT for one of the values (either instance or username) this works fine
I suspect it is due to how Application Express interprets the value of :P2_SELECT
Any help would be much appreciated!
Gareth

Thanks Munky that worked a treat!
The next hurdle I have now is that because I have changed the region type to "PL/SQL Function(returning SQL Query)" there is no longer the option to add sorting to the columns as I have had to change the Source option to "Use Generic Column Names (parse query at runtime only)"
I will have a scout around and see how I can get around this

Invalid Column Name message in the subquery

Hi All, I am receiving the invalid column name message in the subquery. Please help me if there is any work around or change in the query:
Sample query:
update table1 set table1.column1 =
(Select column1 from
(Select column1 from table2 where
table1.columnX = table2.columnX
order by table2.columnM desc,table2.ColumnN desc,
where rownum =1)
When i run the above query i am receiving the following error message:
ORA-00904:invalid column name at table1.columnx.
This column is already existing in table1 and looks like this table is not recoginzed inside of the subquery.
I am trying to update table1.column1 using the first value from table2 after ordering by table2.columnM desc, table2.columnN desc. (ColumnM and ColumnN are the Date columns which i need to perform the sorting). I am new to sql/Plsql. Thanks in Advance for help....

The problem is that you can not refer to columns from the outer table from inside a second subquery inside your subquery. Only one level of subquery can be used to transport the column name,.
A solution can be to use groups and aggregation functions instead of rownum = 1.
The following might work.
untested
update table1
set table1.column1 =
(Select max(column1) keep (dense_rank first over table2.columnM desc,table2.ColumnN desc)
   from table2
   where table1.columnX = table2.columnX
   ) Another way can be to to make a UNCORRELATED subquery first and then filter on that uncorrelated query with the column name from the outer statement.
This time I use a analytic function.
untested
update table1 u
set u.column1 = (select v1.column1
   from
     (Select t2.column1, t2.columnX, row_number over (partition by t2.column1, t2.columnX order by t2.columnM desc,t2.ColumnN desc) as rn
      from table2
      ) v1
   where v1.columnX = u.columnX
   and v1.rn = 1
where /* where clause is missing! */
