How to display column specified in group by clause only once?

I've a result coming out of a sql query that uses group by clause as follows:
2008-07-25 19" LCD Screen 5
2008-07-25 HP Printer     4
2008-08-01 Hanging Files 11
2008-08-01 Stapler     3
2008-08-15 19" LCD Screen 5
2008-08-15 Hanging Files 14
What should I do in the query to display the result set as follows:
2008-07-25 19" LCD Screen 5
     HP Printer     4
2008-08-01 Hanging Files 11
     Stapler     3

Hi,
That's a display issue, and display issues are best handled by the front end.
What is your frone end?
If it's SQL*Plus, you can use the BREAK command.
For example:
BREAK ON deptno     NODUPLICATES
SELECT       deptno
,       ename
FROM       scott.emp
ORDER BY deptno
,            ename
;Output:
`   DEPTNO ENAME
        10 CLARK
           KING
           MILLER
        20 ADAMS
           FORD
           JONES
           SCOTT
           SMITH
        30 ALLEN
           BLAKE
           JAMES
           MARTIN
           TURNER
           WARDNote that deptno is never NULL: KING and MILLER have deptno=10; but it doesn't show in the display, because it's the same as the deptno on the previous row.
NODUPLICATES is actually the default, so you could just say
BREAK ON deptnoThe BREAK command remains in force until you end the session (or un-do it, e.g. with "CLEAR BREAKS")
Remember to issue the BREAK command at least once in the session before running the query.
To get the same results in SQL, use the analytic ROW_NUMBER function.

More than 1 column in the group by clause

DB Version:10gR2
I understand the basics of GROUP BY clause. I have a question on why we have on more than 1 columns in GROUP BY clause.
In the below example, the course name by itself does not make up a group. A Course name plus its BeginDate make up a group. This is the whole point of having more than 1 columns in the GROUP by clause. Right?
SQL> select r.course, r.begindate , count(r.attendee) as attendees
3   from registrations r
4   group by r.course, r.begindate

Thanks Dmorgan. I am just learning the basics of GROUP BY clause. I have noticed that all Non-aggregate columns in SELECT list have to be present in the GROUP BY clause. I thought it was a "syntactical requirement". Now, i realise that these columns are present in the GROUP BY clause because only a combination of columns make up a group.Well, it is a bit of both actually. It is a syntactic requirement that all non-aggregated columns in the select list must appear in the group by clause. However, the non-aggregated columns in the select list is what defines your group. Your two examples define two different groups, and would answer two different questions.

How to use order by within Group by clause

Hi All,
I need a help as to how should i use the Order by clause so that the data should be in order with respect to one column, and at the same time whole data is grouped by some other column...like
Select RaceNo,Venue,FP,BP from Race group by RaceNo
Here I want to order by FP in ascending order for each group. When i am using it , whole order is changing.
Can anybody suggest me how to use order by clause that would apply to each group of data.
Thanks .

order by clause should be used at the last in any query.......but in group by clause u can't use use that becoz u group according to column then no ordering is needed there......if u want to filter something then u can use having clause and later if u need to arrange then u can use order by clause.........
i hope this eg.l gives u some clarification....
e.g
select deptno,count(empno)
from dept
group by deptno
having count(empno) > 10
order by deptno

Select columns not in group by clause

Hi Guys,
I want to fetch columns from a table which are not in group by clause. The catch here is that I also need a count and decode column..
SELECT col_A, col_B, decode(col_C, '10', '10', '26', '26', '00') col_CT, col_X, col_Y count(*) CNT
FROM TABLE_T
WHERE col_B IN (100,101,102) AND col_C IN ('44','45','10','26')
GROUP BY col_A, col_B, decode(col_C, '10', '10', '26', '26', '00')
ORDER BY col_CT
Since, col_X and col_Y are not in GROUP BY clause, it throws error. Also, decode/count of the columns makes it more complex.
Please help me on this.
Thanks,
Amy

Hi, Amy,
Welcome to the forum!
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statments, relevant columns only) for all tables involved, and the results you want from that data.
Always say which versionof Oracle you're using.
How to do what youy want depends on what you want, which is unclear.
If you say "GROUP BY a, b, c", that means you only want one row of output for each distinct combination of a, b and c. How do x and y fit into that? Do you want a separate output row for each distinct combination of a, b,c, x and y? Then add x and y to the GROUP BY clause. If you don't want separate rows for each combinataion of x and y, what do you want when a group has more than 1 value for either of them?
You can simplify the code a little by doing the DECODE in a sub-query; then you can use the alias col_ct as many times as you like in the main query. That will make the code easier to maintain, too.

How to include case stmt in group by clause

Hi i have a question,
How do i include a case statement in the group by clause?
For example:
Select
(case when x.ctry is null then y.ctry else x.ctry end) as coo,
sum (x.in_amt)
from
tbl1 x,
tbl2 y
where
x.id = y.id
group by
(case when x.ctry is null then y.ctry else x.ctry end)
Assume, I have got millions of records in both the tables, then my guess is, the above query might take huge time to complete.
Any alternate method to do this?

To remove the expression from the GROUP BY clause. I didn't advocate any performance improvements, did I?No you didn't. And your advice can indeed remove the expression from the GROUP BY clause. But I'm still puzzled as to why that would be a goal in itself.

How to display empty months when grouping records by month

Guys, I've got a recordset that successfully displays all
records in the
table grouped according to the month that the record was
created in.
This allows me to display a Monthly tally (a bit like a
barchart - where the
height of the column is derived by the qty of records for
that given month)
for each of the months in the year so far. However, it dawned
on me today
that if there was no activity in a given month, the month
simply doesn't
appear at all, rather than displaying but showing "0" as I
would prefer.
For example, the type of thing I want to display onscreen is:
Month 1 2 3 4 5 6 7 8 9 10 11 12
But let's say there were no records inserted in months June
to September
(inclusive), what I'm actually getting onscreen is:
Month 1 2 3 4 5 10 11 12
But what I actually want to appear onscreen is:
Month 1 2 3 4 5 6 7 8 9 10 11 12
I hope that makes some kind of sense...
I'm using Dreamweaver CS3, ASP/VBScript, and MySQL.
My current SQL Statement is as follows:
SELECT Count(AffiliateID) AS TotalClicks, MONTH(`VisitDate`)
AS Month
FROM tbl_affiliaterefferals
WHERE `AffiliateID` = "49" AND YEAR(`VisitDate`) =
YEAR(Now()) GROUP BY
MONTH(`VisitDate`)
ORDER BY MONTH(`VisitDate`) ASC
I figured one workaround would be to have 12 separate
recordsets - one for
each month - on the one page, but there must be a cleaner way
of doing it
surely?
Any/all help greatly appreciated.
Regards
David

Hi Joe,
I've simply got a table, within one cell of which is another
table to which
I've applied a background colour and am specifying the height
of the <td>
cell as the qty of the number of records returned for Month 1
of the current
year. Then I'm applying a repeat region to the <TD>
cell containing the
table that varies in height, in order to force the table to
repeat
horizontally according to the number of records (months)
retrieved from the
database.
The code for the table is in the attached txt file.
I appreciate your time in responding however you must have
missed my
comments about what I'm working in as I'm working in
ASP/VBScript and
haven't the first clue when it comes to PHP.
I don't suppose you know or can point me in the direction of
an ASP
equivalent of your suggestion?
Regards
David

How to add columns in the Group Custom Columns

Hi,
In a group, if you select Edit Group link, and select the Columns tab, and then select the "Modify" button, then select a target type from the drop down, you can pick listed columns and move it to the Selected Columns list. I am interested in adding a column in the drop down list, how do I do that? If the target type is a plug-in that I created, then what properties I should set in the metadata xml file?
Thanks for the help.

As far as I am aware, there are no properties in your plugin's target type metadata XML file that relate to what columns show up in the Groups UI in the EM console. I suggest pursuing this as a bug against the Groups UI.

How to display Column List (Search Bar - Do Not Display) in Ascending Order

Hi,
I am having a Interactive Report..
In the Search Bar we have Select Columns, under that we have Do Not Display.
where all the columns (currently not displayed) are listed.
How can we display these columns in Ascending order
Thanks,
Deepak

Do you want to display these columns in the IR?
If yes. Select the column you want to display and click the the '>'.
In the interactive report regions - source, where you have your query to select the columns use order by to sort them in assn order.
Do you want to keep these columns as 'Do not display' and have them in assn order there?
Select all columns to display and move the columns back to the 'Do not display' region one by one making selections in assn order.
Or in the query select the columns in the order desired.
I don't know if I am helping. I fell like I got your question all wrong. Still...

Display column name with Group by

Hi,
I am having a table with a column series which is repeating.
When i want to get all the unique series and its count, in the normal sql, I am using
select series,count(1) from temp_table group by series;
But the same is not working in the case of SQLX,
I want <root><series><name count="8">series1</name><name count="18">series2</name></series></root> kind of output.
But when i use SQLX query,
select XMLElement("root",XMLElement("series",XMLAgg(XMLElement("name", ... group by series
it is returning more than one record.
How to get the desired result??
Thanks
Guru

I wanted to know whether it is possible to get the count in the sqlx itself, Can anybody point me to any SQLX query for that?

How to display Column of a particular list to page using Content Search Webpart?

How to display Column data in one row

Hello,
I have one Employee with 4 effective date displayed in one column. Effective date is drived by Reason of : New Hire, Rehire, Transfer etc.
I want to show the effective dates for one reason in one single row. For example a person was rehired 4 times it will show as
1006555 6/12/2006 1/2/2007 6/11/2007 5/12/2008 12/29/2008 5/17/2010
It's currntly showing as:
AUDITEFFECTIVEDATE_3
6/12/2006
1/2/2007
6/11/2007
5/12/2008
5/17/2010

Well that's a little tougher... For a solution to work, you're going to need to find a way to differentiate between the the specific hiring events. Without seeing what data is available, I'd say start looking at the use of running totals... or in this case a running count.
Set it up to reset on EmployeeID and count each "event", incrimenting up with each instance.
Then your formula would look more like this...
IF {EventType} = "Rehire" AND {#RTotal1} = 1 THEN AUDITEFFECTIVEDATE_3
IF {EventType} = "Exit" AND {#RTotal1} = 1 THEN AUDITEFFECTIVEDATE_3
IF {EventType} = "Rehire" AND {#RTotal1} = 2 THEN AUDITEFFECTIVEDATE_3
IF {EventType} = "Exit" AND {#RTotal1} = 2 THEN AUDITEFFECTIVEDATE_3
IF {EventType} = "Rehire" AND {#RTotal1} = 3 THEN AUDITEFFECTIVEDATE_3
IF {EventType} = "Exit" AND {#RTotal1} = 3 THEN AUDITEFFECTIVEDATE_3
IF {EventType} = "Rehire" AND {#RTotal1} = 4 THEN AUDITEFFECTIVEDATE_3
IF {EventType} = "Exit" AND {#RTotal1} = 4 THEN AUDITEFFECTIVEDATE_3
This issue then becomes an issue of space on the report. You end up wasting 1/2 of your horizontal space trying to allot for one odd ball... You'll also get to re-work the report if the same employee goes for rounds 5, 6 or 7...
HTH,
Jason

How to display Columns in Alphabatical order when using DESC command

A table column is inserted not in alphabetic order during the table creation definition.
