How to switch column names without moving song list?

Somehow I put the song names under the column labled "Artist" and the artist under "Names".
How can I change these column titles without having to retype each song title and artist under the correct column names?
Thanks

thanks for your reply
i 'm doing what exactly you mention here .
my problem here is
i have 15 columns
i am executing a query based on the values of the column(column name) in the target page
1)here i am passing(all) the column values to the next page-but i want to pass only one column values(column name)
when i click on any cell of that column
OR
2)i can pass all column name to target page -there(in the target page) i can filter out
i think option 1 would good if you filter out the unwanted columns

How to get column names in table maintenance dialog?

I created a new Z table and created a maintanance dialog so that I can maintain the table through sm30. i don't see columns names on maintenance screen, just a "+" sign for each column! Could someone please tell me how to display column name?
Thanks.
Mithun

Hello Mithun
The column texts are taken from the field descriptions of the data elements used in your z-table. A "+" sign usually indicates that none of the field descriptions of the data element has been maintained.

how to pass column name at run time in function as parameter.
thank in advance
pramod patel

Hello,
Using dynamic sql you can pass column name to function. well I am not getting what you really want to do ? Please write in more detail. By the way I am providing one example here. see it uses dynamic sql.
Create or replace function fun_updtest (p_columnname_varchar2 in varchar2,
p_value_number in number)
return number is
v_stmt varchar2(500);
begin
v_stmt := 'update emp
set '||p_columnname_varchar2||' = '||to_char(p_value_number)||'
where empno = 7369';
execute immediate v_stmt;
return 0;
commit;
end;
call to this function can be like this..
declare
v_number number;
begin
v_number := fun_updtest('SAL',5000);
end;

How to validate column name in dynamic made sql?

Oracle db, jdbc, web app with struts2/spring.
Example table could be this:
CREATE TABLE album
album_id number(10) not null,
artist varchar2(50) not null,
title varchar2(50) not null,
released DATE,
CONSTRAINT album_pk PRIMARY KEY (album_id)
);In may app the user MAY search, MAY sort, and the result from an select might return 10.000 rows.
The basic sql usually look like this.
String sql = "select album_id, artist, title, released from album";Then in the html page the user can add search criteria for each column. Like type "iron maiden" in artist field, put "1982" in released field. And you all know what the exceptionally result should be from that :)
Now I need to modify the sql a bit:
if( artist search field contains stuff )
sql = sql + " where nvl( artist,' ') like ?"
}we try use prepared statements right? So we use ? as placeholders, and then add "iron maiden" into this statement later on.
Nice, no big fuzz right, and pretty safe from sql injections i guess.
But now I have to have an if/else for every single field in the table. Boring. In my app I got like 25 tables like this, with 20 columns minimum. Copy/Paste have never been so boring.
I also might have to add "order by" with user selected columns and their order. I have to count the query to get total result in case i got to split it up in pages. So there is alot of if/else and sql = sql + "more stuff", and sticking to ? and pure prepared statements is impossible.
But doing this is not good either:
for( each element in a map)
sql = sql + " and nvl( " + key + ",' ') like ?"
}Where key is "artist".
In struts and other tag libs its easy to make kode like:
<s:textfield name="model.addSearch( 'artist' )" value="%{model.getSearch( 'artist' )}" size="30" />
Silly example maybe, but just to make a point.
Inputed values in an html form, can very easily be a part of a dynamic created sql - which becomes a security problem later on.
Artist is an column name. Key should be validated if it contained an valid column name.
I could make a list of strings, containing valid column names to check against.
My question is if there is possible to get this type of information from the database, so I don't have to hand-make these lists?
But I also want to keep the number of heavy and slowing queries down.
My app have like 25 tables now, and I could easily get away with hand-make everything, copy/paste around etc. But I have more projects and this question will be here next time too. And after there again...

Metadata. Then I have to query the database, take the result and use it for validating of input. If my sql only query 1 table, then this is ok. In this case I could do with that. But if the sql query mutliple tables, with sub-selects, unions etc. Then I might have to query all tables first, and even then I might not have what I want.
The best way is of course to run the query, then get the metadata from that query - cause then im 100% sure what columns will be returned, and then I can validate with that.... 1 query is often not that slow. But I might query once to find total number of rows the query return in order to decide if we need to page the result. then query to get the metadata for validating input, then query to get the result... Maybe this is ok -but my head don't like it as an general ok thing to do, but I can't really say why...If you have a gui screen then it needs to correspond to some specific query. It can't be all possible combinations.
So once you know the query you can obtain the meta data using a query that returns no results. Like the following.
select * from mytable wheren 1 = 0

Jschell:
I agree to what you say. I don't understood everything you said tho.
Im not sure if you talk about having 1 search field (like google), and you input stuff there that might be in any columns.
I have several search fields in one-to-one relasionship with view column/sql query column.
Then you already know what the field represents. So validate it in the gui and not via the database.
The first is way more advanced since you have to cover any input, any column, any case etc. Pluss add ranking. Lots of work for someone who have done little searchengines.
Latter is simpler, but might also be limiting.Huh?
As an example if you have a call center then the operators are not going to be doing unrestricted searches to find customers. They are going to look using a very limited set of data like the customer name and telephone number.
>
My job is very much like an consulent. They got an app, I shall add a new feature. The app is old and ugly coded. My boss ask how long it takes to make this, I say 2months, he decide 1 month. My dev time for features is rarely above 1 month, and I don't make much new apps.
So I don't have the time to make advanced codegenerator, or spend time to evaluate various frameworks. Bringing an framework into the existing code is actually difficult. But I do want to improve the code, and add good code into the existing app that can be extended without evil pain.
That doesn't jive with your OP. You made the following statement "My app have like 25 tables now, and I could easily get away with hand-make everything,...".
That suggests that you are doing much more than simply updating an existing application.
If you only need to add one new field then you should do only that. You shouldn't be attempting to add a system spanning validation system.
On the other hand if you are in fact adding a validation system, then code generation makes it likely that it would take less time or no more than the same. And it is less likely to introduce bugs.
Learn how to make an code generator? Well I guess thats what I asked help for - point me in the right direction if you could pls. Putting strings together to become code in an logic way is usually manageable, at least for simple querys. Evaluating that the generated code is good/safe - got no good clues...
Learn about frameworks? Got no time. Hope I will get the time, but I won't. The customer must want to spend the money so I can get the time, that won't happen cause an framework does not add features, its only cost saving in terms of dev time, and maintenance time. The customer have no such focus/interest. They got a bit money to spend now and then regularily. i.e. government.
I just want to try code as good as possible so I save myself from errors, painfull rewrites, and dev-time that gets out of proportions because of stupid code. So the question is actually about me trying to improve myself, its just that i don't know how right now.There are two goals.
1. Implement a specific feature in an existing application.
2. Learn a new way to solve problems.
Nothing says that the second will help with the first. They should be addressed separately and your post doesn't make it clear what the first is so it is hard to say how it should be down.
As for the second I already made a suggestion which provides two new ways to solve problems.

How to find column names in a table

Am learning the basics of SQL Plus.
Have entered the following query:
SELECT * FROM t_ebb_session;
This gives me the following output.
USER_ID SESSION_ID LAST_ACCE
However LAST_ACCE is not the full name of the column as I get 'Invalid column name when I use it in a select statement.
How do I display the full name?

By default, SQL*Plus will set the column display width of a character column to its size in the database, and the heading will be the column name in uppercase, truncated to fit that width if necessary. (There is a different rule for numeric columns.)
You can override this with the COLUMN command, e.g:
COLUMN some_column_name FORMAT a30 HEADING "Alternative Name"
Check out the SQL*Plus documentation for all the COLUMN options.

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.

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,
function BeforePForm return boolean is
begin
:P_field := <your_function_call>;
return (TRUE);
end;And use that FN_FIELD field in the report.
Hope this will clear your issue.
Regards,
Manu.

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

Hi ,
I am simply reading the excel sheet and writing in a txt file. I have done the following in the switch construct. It works fine but I want to retrieve only the column header. But this code gives me all available strings in the excel sheet. Any pointer would be greatly appreciated.
case SSTRecord sid :
         SSTRecord sstrecord = (SSTRecord) record;
         for (int i=0; i<sstrecord.getNumUniqueStrings(); i++){
              System.out.println(" Column name" + sstrecord.getString(i));
break;bye for now
Sat

try labels:
        case LabelSSTRecord.sid:
            LabelSSTRecord lrec = (LabelSSTRecord) record;
            if (lrec.getRow() == 0) {
                System.out.println(" Column name "
                        + sstrec.getString(lrec.getSSTIndex()));
            break;
