Selecting only one row from a query

Hi,
I am using database version 10.2.0.4.0
I have 2 tables:
artist(artistid, artistname, titleid)
trans(transid, datesold, salesprice, titleid, artistid)
This is what i used and got the below results.
SELECT max(worksold) AS mostworksold
FROM (
SELECT artistname, COUNT(t.artistid) AS worksold
FROM table.artist a, table.trans t
WHERE a.artistid = t.artistid
GROUP BY artistname
MOSTWORKSOLD
12
However I also want to show the artist name who sold the most work. So i added artist name in the select, but the result came out very different.
SELECT artistname, max(worksold) AS mostworksold
FROM (
SELECT artistname, COUNT(t.artistid) AS worksold
FROM table.artist a, table.trans t
WHERE a.artistid = t.artistid
GROUP BY artistname
group by artistname;
ARTISTNAME MOSTWORKSOLD
John 3
Mary 4
Alvin 9
Trevor 5
Jess 12
What should I do to make it show only this?
ARTISTNAME MOSTWORKSOLD
Jess 12
Regards,
Keith

Selecting only one row at a time

Hi experts,
i have following doubt regarding selecting rows from a db:
Is there any way of selecting only one row AT A TIME from a dabase just to collect the data in rows instead of in a unique document containing all the rows?
I would like you to ellaborate on this as i need to send only one row to the IE, and then other row, and so on... without throwing any error!
I have seen that there are SELECT SINGLE and SELECT UP TO 1 ROW, but these two methods are only useful when retrieving only one row, and that does not match my requirements. I need to process all the rows but one by one..
I know that we can use the receiver jdbc adapter as if it was a sender by means of its specific datatype, but how to do it row by row??
Hope i had explained well..
Thanks in advance and best regards,
David

Hi kiran,
Yes, my table has 5 not null fields but i am selecting and updating fixes values so i think that I will definetely go for the next solution:
SELECT * FROM t1 WHERE status='0' and ROWNUM<2;
UPDATE t1 SET status='1' WHERE status='0' and ROWNUM<2;
My only concern is if the update will take the same row that the select.... BTW, I think it will
..What do you guys think?
I ve been trying to operate with your proposed queries but i received some errors. Your queries are very interesting but i think that with the above ones i meet my requirements as the status field will be 0 for not processed rows and 1 for precessed ones (and the update will look for the row that meets the same 'where' clause than the select, and then, and only then, it will set status='1').
The only thing i have to care about is what i questioned before.
Thanks a lot and best regards,
David

No, so extract one page, then convert.

Oracle database link to MySQL select only one row

Bianca,
If you log directly into MySQL and issue the same query (select "subject" from "main_pages";) what data is returned?
I looks to me that you count is the number of rows in the entire table "main_pages"
while you select is for the data in the "subject" column only.
This seems to indicate that you have just one row in that subject column.

Matt
WHAATT?
What do you mean by "just one row in that subject column"?
That makes no sense at all. A row is a row. A column is a part of a row. All rows have all columns, though not all columns of all rows will necessarily have an assigned value. Lacking a WHERE clause to filter rows, any SELECT should return all rows.

Same query canreturn rows in different order next time you run it unless you specify ORDER BY. Only ORDER BY guarantees order, so when you say first row/second row you must provide ordering criteria.

Thanking you in advance!

Hi,
If you have the database toolkit you can delete a row using just a SQL Query to "DB Tools Execute Query.VI"
Example:
DELETE FROM Table name Where SerialNum='Value' And Date='Value' And Time='Value'

Selecting a one row from the database is not working

Hi all I am having a small problem with getting a row from my database to show up. Here is the code for the search that I want to do
String item; String columnName; String result; columnName = (String)searchBox.getSelectedItem(); item = searchField.getText().trim(); String tableName = "employee"; if(item == null || item.equals("")){ System.out.println("No Text entered"); }else{ try { result = sql.retrieve_From_Database(columnName, tableName, item); System.out.println(result); } catch (SQLException e1) { sql.displayErrors(e1); }
Here is the code for the retrieve_From_Database function.
protected String retrieve_From_Database(String columnName, String tableName, String item) throws SQLException{ ResultSet rs = null; Statement sm = null; sm = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_READ_ONLY); rs = sm.executeQuery("select * from " + tableName + " where " + columnName + " = " + item); result = rs.getString(columnName); if(result == null){ System.out.println("Error in retrieve"); return new String("No results in DB"); }else{ System.out.println(result); return result; } }
When I run the first code I get an error of SQL Exception: Unknown column 'anthony' in 'where clause'. But yet when I run the query of
Select * from employee where FirstName = 'anthony'
within the mysql commandline I get the proper result. So my question is why when running this in the command line do I get the proper result but when running the code I do not?

Hi. The problem is clear in the original post. The OP is trying to use PreparedStatement
parameters to fill out general portions of the SQL query, instead of only data values.
He is hoping to put in a column name. That will never work. Only data values are settable.
HTH,
Joe WeinsteinActually, no. There's no PreparedStatement there at all. It appears that his problem is that, while the working query entered directly in the client is
Select * from employee where FirstName = 'anthony'the query he's constructing in his code is
Select * from employee where FirstName = anthonySince there are no quotes around anthony, it's treated as a column name.
If he had properly used PreparedStatment as suggested in reply 1, that would not be an issue. My guess, however, is that when he claims he's using PS, it's as Tolls suggested a couple of posts ago--he's simply replacing the Statement with a PreparedStatement, but not using the parameters as suggested.
The wrong thing for OP to do at this point is see my above comment about the quotes and explicitly add them in the query string. The right thing to do, of course, is to actually use PS's parameters.

Pick only one row from the repeated rows

As you see that the first record on each repeated row sets are required

Hi,
Using the aggregate FIRST (or LAST) function like that, there's no guarantee that all of the output values on the same row will come from the same row in the original table. To do that, you can use the analytic ROW_NUMBER function, like this:
WITH     got_r_num     AS
     SELECT     name, address, zip, ...
     ,     ROW_NUMBER () OVER ( PARTITION BY name
                               ORDER BY         address
                         ,                zip
                       )      AS r_num
     FROM     table_x
SELECT     name, address, zip, ...
FROM     got_r_num
WHERE     r_num     = 1
;This assumes the "first" row is the one with the first address (in alphabetic order), and, in the event of a tie, the one with the lowest zip (however "lowest" is defined for zip). You can specify any order you want in the analytic ORDER BY clause.
I hope that answers your question.
If not, what is your question? Use words other than those you've already used to describe what you want to do.
Explain exactly what "first" means in this problem.Point out where the query above (or the one posted by Claytonian, if that seems closer) is getting the wrong results, and explain how you'd get the right results in those places.
If necessary, post new sample data (either CREATE TABLE and INSERT statements, or a WITH clause, as Claytonian did) and the results you want from that data.

Select event not triggered in table with only one row

Hi all,
I am building a BI VC application where query data is displayed in a table. When the user clicks on a table row another query is then triggered and output in a second table. The output from table 1 is linked to the input of query2/table2 with a select event.
The problem that I am facing is that if there is only one row in table 1, the select event is never triggered. If, however there are two or more rows in the table the select event is triggered and query 2 is executed. I have searched the forums but all I could find on select event problems was how to avoid the initial select event.
Has anyone else experienced this issue and what is the workaround or is this a bug in Visual Composer? We are on VC 7.0 SP19.
Cheers,
Astein Meland

Thanks Chittya,
Yes we have considered this option as well. But as we have more than one table linked together we would like to avoid having to manually click several buttons.
In the end I found Note 1364334 describing bugfixes released in VC 7.0 SP20:
"Normally, when a Visual Composer table is populated from a data service, the first row is selected by default. However, we have found that if only one data row is returned from the data service, this row is not selected by default and cannot be manually selected by clicking on it either."
So I think we will just have to upgrade our Portal to the latest support packs to solve this problem.
Thanks,
Astein

Issue with Selection Listener when the table has only one row

Hi All ,
I have developed a table in which I am using Selection Listener to perform some task when any row is selected.
It is working fine when I have more than 1 row in the table, but when I have only one row in the table , the selection listener do not call the corresponding method in bean.
I understand that selection event will be raised only when the row is changed, but in the use case when only one row is there, what should be done to make the selection listener work ?
In the selection listener I have written code to make the selected row as current row , and perform the required task.
Please suggest a way out for this situation.
Thanks in advance.

Newbie question: Select one row from table in PL/SQL

Hi,
I want to select one row from the table Employee where Emplyoyee Number is say 200. This is a simple SQL query, but I don't know the equivalent PL/SQL format. I will have 3 out params here - Id itself, Name, Salary. I will then have to populate a java resultset object from these out params.
Later, I'll have to use cursors to retrieve more than one row.
Thanks for any help.

Perhaps something like
CREATE OR REPLACE PROCEDURE get_employee( l_id IN OUT employee.id%TYPE,
                                          l_name OUT employee.name%TYPE,
                                          l_salary OUT employee.salary%TYPE )
AS
BEGIN
SELECT name, salary
    INTO l_name, l_salary
    FROM employee
   WHERE id = l_id;
END;Justin

Fetching more than one row from a table after selecting one value from the dropdown

Hi Experts,
How can we fetch more than one row from a table after selecting one value from the dropdown.
The scenario is that I have some entries in the dropdown like below
A               B               C
11256          VID          911256
11256          VID          811256
11256          SONY      11256
The 'B' values are there in the dropdown. I have removed the duplicate entries from the dropdown so now the dropdownlist has only two values.for eg- 'VID' and'SONY'. So now, after selecting 'VID' from the dropdown I should get all the 'C' values. After this the "C' values are to be passed to other methods to fetch some data from other tables.
Request your help on this.
Thanks,
Preeetam Narkhede.

Hi Preetam!
I hope I understand your request proberly, since this is more about Java and less about WebDynpro, but if I'm wrong, just follow up on this.
Supposed you have some collection of your original table data stored in variable "origin". Populate a Hashtable using the values from column "B" (let's assume it's Strings) as keys and an ArrayList of whatever "C" is (let's assume String instances, too) as value (there's a lot of ways to iterate over whatever your datasource is, and since we do not know what your datasource is, maybe you'll have to follow another approach to get b and c vaues,but the principle should remain the same):
// Declare a private variable for your Data at the appropriate place in your code
private Hashtable temp = new Hashtable<String, ArrayList<String>>();
// Then, in the method you use to retrieve backend data and populate the dropdown,
// populate the Hashtable, too
Iterator<TableData> a = origin.iterator();
while (a.hasNext()) {
     TableData current = a.next();
     String b = current.getB();
     String c = current.getC();
     ArrayList<String> values = this.temp.get(b);
     if (values == null) {
          values = new ArrayList<String>();
     values.add(c);
     this.temp.put(b, values);
So after this, you'll have a Hashtable with the B values als keys and collections of C values of this particular B as value:
VID --> (911256, 811256)
SONY --> (11256)
Use
temp.keySet()
to populate your dropdown.
After the user selects an entry from the dropdown (let's say stored in variable selectedB), you will be able to retrieve the collection of c's from your Hashtable
// In the metod you handle the selection event with, get the c value collection
//and use it to select from your other table
ArrayList<String> selectedCs = this.temp.get(selectedB);
// now iterate over the selectedCs items and use each of these
//to continue retrieving whatever data you need...
for (String oneC : selectedCs) {
     // Select Data from backend using oneC in the where-Clause or whatever...
Hope that helps

Keeping only one row with information from several rows?

Hi,
I have a table with companies. The companies appearing more then once in the table, with different information in different columns. How do I keep one row from each company with all information..?
Example:
Company State City Country
CompA WA Seattle null
CompA null null USA
CompB null null USA
CompB TX null null
...and so on.
And I want out of this:
CompA WA Seattle USA
CompB TX null USA
Any tips?

declare @temp table
company char(6),
state char(10),
city char(20),
country char(10))
insert into @temp values ('CompA','WA','Seattle',null),('CompA',null,null,'USA')
,('CompB','Tx',null,null),('CompB',null,null,'USA')
select max(company),MAX(state),MAX(city),MAX(country) from @temp
group by company
