Newbie Dynamic Group by clause

Example
create table test( awhite numeric(6,0)
, DMonth numeric(2,0)
, Goalnumber numeric(2,0)
, Objnumber numeric(2,0));
insert into test(awhite,DMonth,Goalnumber,Objnumber)
values(5,6,1,1);
insert into test(awhite,DMonth,Goalnumber,Objnumber)
values(8,6,1,2);
insert into test(awhite,DMonth,Goalnumber,Objnumber)
values(12,6,2,1);
insert into test(awhite,DMonth,Goalnumber,Objnumber)
values(16,10,2,1);
insert into test(awhite,DMonth,Goalnumber,Objnumber)
values(4,10,2,1);
===========================
I need this to be ONE query with a parameter
Select SUM(Awhite) SWhite
,DMonth
,CASE WHEN &groupbyobj<2 THEN
to_number('99')
ELSE
Goalnumber
END Goalnumber
,CASE WHEN &groupbyobj<3 THEN
to_number('99')
ELSE
Objnumber
END Objnumber
FROM Test
GROUP BY Goalnumber,Objnumber,DMonth
============================
So when the groupbyobj=3, I want the output to look like
SWHITE DMONTH GOALNUMBER OBJNUMBER
5 6 1 1
8 6 1 2
12 6 2 1
20 10 2 1
==============================
So when the groupbyobj=2, I want it grouped by GOALNUMBER
SWHITE DMONTH GOALNUMBER OBJNUMBER
13 6 1 99
12 6 2 99
20 10 2 99
So when the groupbyobj=1, I want it grouped by DMonth
SWHITE DMONTH GOALNUMBER OBJNUMBER
25 6 99 99
20 10 99 99
I ADDED the above "99" to the output above. I could not get my query to output that.
QUESTION- How can I create A DYNAMIC Group by clause based on the parameter
(Groupbyobj) Selected?
TIA

I noticed I got the numbers 1 until 3 just the other way round, so here is a new version.

Hi Expert,
Here i have problem :
i want display record with passing group by clause Parameter
Example :
Select zone,district,postal,count(Do_no) ,sum(Sales_Amt)
from DLV_ORD_mast
group by :zone,:district,:Postal
1-o/p like :
if user pass the :zone parameter in group by clause then record display like below o/p
zone count sls_amt
South 2 1000
central 3 5000
East 4 600
2-o/p
if use pass the :District parameter in group by clause then record display like below O/P
zone count sls_amt
South/Dist1 2 1000
central /Dist2 3 5000
central /Dist3 1 500
East /Dist4 4 600
2-o/p
if use pass the :postal parameter in group by clause then record display like below O/P

Build a block one a Query FROM clause, like
SELECT GROUPCOL,
       CNT,
       SUMM
FROM (Select zone GROUPCOL,
               count(Do_no) CNT,
               sum(Sales_Amt) SUMM
          from DLV_ORD_mast
         group by zone
)Then at runtime, change the the block QUERY_DATASOURCE_NAME by SET_BLOCK_PROPERTY depending on the parameter, e.g. to
SELECT GROUPCOL,
       CNT,
       SUMM
FROM (Select zone ||', '|| DISTRICT GROUPCOL,
               count(Do_no) CNT,
               sum(Sales_Amt) SUMM
          from DLV_ORD_mast
         group by zone ||', '|| DISTRICT
)

Group by clause and having clause in select

hi frnds
plz give me some information of group by and having clause used in select statement with example
thanks

The Open SQL statement for reading data from database tables is:
SELECT      <result>
INTO      <target>
FROM      <source>
[WHERE    <condition>]
[GROUP BY <fields>]
[HAVING   <cond>]
[ORDER BY <fields>].
The SELECT statement is divided into a series of simple clauses, each of which has a different part to play in selecting, placing, and arranging the data from the database.
You can only use the HAVING clause in conjunction with the GROUP BY clause.
To select line groups, use:
SELECT <lines> <s1> [AS <a1>] <s2> [AS <a2>] ...
               <agg> <sm> [AS <am>] <agg> <sn> [AS <an>] ...
       GROUP BY <s1> <s2> ....
       HAVING <cond>.
The conditions <cond> that you can use in the HAVING clause are the same as those in the SELECT clause, with the restrictions that you can only use columns from the SELECT clause, and not all of the columns from the database tables in the FROM clause. If you use an invalid column, a runtime error results.
On the other hand, you can enter aggregate expressions for all columns read from the database table that do not appear in the GROUP BY clause. This means that you can use aggregate expressions, even if they do not appear in the SELECT clause. You cannot use aggregate expressions in the conditions in the WHERE clause.
As in the WHERE clause, you can specify the conditions in the HAVING clause as the contents of an internal table with line type C and length 72.
Example
DATA WA TYPE SFLIGHT.
SELECT   CONNID
INTO     WA-CONNID
FROM     SFLIGHT
WHERE    CARRID = 'LH'
GROUP BY CONNID
HAVING   SUM( SEATSOCC ) > 300.
WRITE: / WA-CARRID, WA-CONNID.
ENDSELECT.
This example selects groups of lines from database table SFLIGHT with the value LH for CARRID and identical values of CONNID. The groups are then restricted further by the condition that the sum of the contents of the column SEATSOCC for a group must be greater than 300.
The <b>GROUP BY</b> clause summarizes several lines from the database table into a single line of the selection.
The GROUP BY clause allows you to summarize lines that have the same content in particular columns. Aggregate functions are applied to the other columns. You can specify the columns in the GROUP BY clause either statically or dynamically.
Specifying Columns Statically
To specify the columns in the GROUP BY clause statically, use:
SELECT <lines> <s1> [AS <a 1>] <s 2> [AS <a 2>] ...
               <agg> <sm> [AS <a m>] <agg> <s n> [AS <a n>] ...
       GROUP BY <s1> <s 2> ....
To use the GROUP BY clause, you must specify all of the relevant columns in the SELECT clause. In the GROUP BY clause, you list the field names of the columns whose contents must be the same. You can only use the field names as they appear in the database table. Alias names from the SELECT clause are not allowed.
All columns of the SELECT clause that are not listed in the GROUP BY clause must be included in aggregate functions. This defines how the contents of these columns is calculated when the lines are summarized.
Specifying Columns Dynamically
To specify the columns in the GROUP BY clause dynamically, use:
... GROUP BY (<itab>) ...
where <itab> is an internal table with line type C and maximum length 72 characters containing the column names <s 1 > <s 2 > .....
Example
DATA: CARRID TYPE SFLIGHT-CARRID,
      MINIMUM TYPE P DECIMALS 2,
      MAXIMUM TYPE P DECIMALS 2.
SELECT   CARRID MIN( PRICE ) MAX( PRICE )
INTO     (CARRID, MINIMUM, MAXIMUM)
FROM     SFLIGHT
GROUP BY CARRID.
WRITE: / CARRID, MINIMUM, MAXIMUM.
ENDSELECT.

Why is the GROUP BY clause not working in my Query?

Dear All,
Below is the Query for a Summary Debtors Aged Analysis.
The GROUP BY clause does not seem to be working.
The Query returns all the unpaid invoices, instead of a single total row for each Customer.
If a Customer X has 10 unpaid invoices, 10 rows are displayed - one for each invoice.
I was expecting only 1 row for Customer X, 1 for Customer Y, etc.
This is what GROUP BY is supposed to do, but it is not doing its work.
What has gone wrong?
Thanks
Leon Lai

Dear Neetu,
Thanks for your reply.
This Query is a modification of the Query you posted in SAP B1 SQL TIPS & TRICKS
http://wiki.sdn.sap.com/wiki/display/B1/SAPB1SQLB-FNDebtorsAgingReportbydate
So, maybe instead of referring to my Query, let's refer to yours. It may be easier for you to understand me.
Once I understand the problem, I can adapt your query to suit my requirements
So, let's start with a clean slate:
The Query you have posted is for a DETAILED Debtors Aging Report.
This lists all outstanding invoices, and ages them in the Age Brackets.
What I want is a SUMMARY Debtors Aging Report.
This will give the total amount owed by each Customer, and this amount is broken down in the Age Bracket Columns
There will be a single row listed for each customer, something like this:
Customer     Total Due     Current      1 Mth          2 Mth         3 Mth etc
Alfred       500,000       300,000       200,000
Charles      800,000                     100,000       300,000       400,000
How can you modify your query to make it become a Summary Report (1 line for each customer even if he has many invoices)?
Thanks

How to write a SQL Query without using group by clause

Hi,
Can anyone help me to find out if there is a approach to build a SQL Query without using group by clause.
Please site an example if is it so,
Regards

I hope this example could illuminate danepc on is problem.
CREATE or replace TYPE MY_ARRAY AS TABLE OF INTEGER
CREATE OR REPLACE FUNCTION GET_ARR return my_array
as
     arr my_array;
begin
     arr := my_array();
     for i in 1..10 loop
          arr.extend;
          arr(i) := i mod 7;
     end loop;
     return arr;
end;
select column_value
from table(get_arr)
order by column_value;
select column_value,count(*) occurences
from table(get_arr)
group by column_value
order by column_value;And the output should be something like this:

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

-- SQL -- GROUP BY clause: non-aggregate fields mandate

Hello,
I was studying Databases, (particularly the retrieval of the data), and found something interesting.
While using an Aggregate Function in the SELECT clause, it is mandatory to have all the non-aggregate fields in the SELECT clause to be there in the GROUP BY clause.
For example,
SELECT dept_no, SUM(salary)
FROM employee
GROUP BY dept_no;
The above SQL works fine.
But, what if the user misses the dept_no in the GROUP BY clause or he/she misses the GROUP BY clause itself?
Certainly, it is an error.
Why is this error not handled by the database. I mean, the database should be smart/intelligent enough to add the GROUP BY clause by itself. So suppose, if I miss out the GROUP BY clause or miss a non-aggregate field from the SELECT clause when I am having at least one aggregate function on a field with at least one non-aggregated field in the SELECT clause, the database should check the GROUP BY clause at time of compilation and add the mandate missed out fields in the GROUP BY clause.
Example,
SQL1:_
SELECT dept_no, SUM(salary)
FROM employee
GROUP BY dept_no;
SQL2:_
SELECT dept_no, SUM(salary)
FROM employee;
Here, the SQL1 and SQL2, both should give me same outputs without an error.
I am unable to understand why is this not handled?

Hi,
998478 wrote:
... If we mix aggregate and non-aggregate values then there must be a GROUP BY clause containing all the non-aggregate values. Why is this not handled by the database/compiler itself? It IS handled by the compiler itself. The compiler handles it by raising an error. The compiler has no way of knowing whether you want to remove something from the SELECT clause, or to add something to the GROUP BY clause, or not to use aggregate functions, or to use more aggregate functions, or some combination of the above. If the compiler re-wrote your code, and did any of these things automatically, it would be wrong more often than it was right, and you would (rightly) be complaining about its behavior.
For example, this is clearly wrong:
SELECT    deptno
,       job
,       SUM (sal)
FROM       scott.emp
GROUP BY deptno
;What is the right way to fix it?
<h3>1. Remove something from the SELECT clause</h3>
SELECT    deptno
,       SUM (sal)
FROM       scott.emp
GROUP BY deptno
;<h3>2. Add something to the GROUP BY clause</h3>
SELECT    deptno
,       job
,       SUM (sal)
FROM       scott.emp
GROUP BY deptno
,         job
;<h3>3. Not use aggregate functions</h3>
SELECT    deptno
,       job
,       sal
FROM       scott.emp
;<h3>4. Use more aggregate functions</h3>
SELECT    deptno
,       MIN (job)
,       SUM (sal)
FROM       scott.emp
GROUP BY deptno
;These aren't all the options, either. For example, the correct fix might be to use analytic functions instead of aggregate functions.
How can anybody say which of these is right? All of them are the right answer for some problem.
By the way, saying that everying in the SELECT clause must be an aggregate or in the GROUP BY clause is a bit over-simplified.
More completely, here are the ABC's of GROUP BY:
When you use a GROUP BY clause and/or an aggregate function, then everything in the SELECT clause must be:
(A) an <b>A</b>ggregate function,
(B) one of the "group <b>B</b>y" expressions,
(C) a <b>C</b>onstant, or
(D) something that <b>D</b>epends entirely on the above. (For example, if you "GROUP BY TRUNC(dt)", you can SELECT "TO_CHAR (TRUNC(dt), 'Mon-DD')").

Use Granfeldts Create Object to create dynamic groups

Trying to use Sorens Granfeldts, Create Object WF activity to create dynamic groups.
In a standard function evaluator activity I generate the Filter as [//WorkflowData/Filter]
The "string" I set it to is:
<Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Dialect="http://schemas.microsoft.com/2006/11/XPathFilterDialect" xmlns="http://schemas.xmlsoap.org/ws/2004/09/enumeration">/Person[ObjectID
= /*[ObjectID = '8dfcb5e8-ff01-400c-8ca7-2a0002d2d2d4']/ComputedMember]</Filter>
In the CreateObject activity I then just have [//WorkflowData/Filter],Filter among the initial values.
The creation works if I remove this attribute so the rest of the attributes seems to be working.
The creation fails however end I get the error below in the Forefront Identity Manager event log.
System.NullReferenceException: Object reference not set to an instance of an object.

   at System.Workflow.Runtime.Scheduler.Run()
Have anyone used this WF activity to create dynamic groups and can tell how to set the Filter?

Hey Kent!
I did the same thing, with Søren`s Create Object WF. I did it like this on the filter part:
<Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Dialect="http://schemas.microsoft.com/2006/11/XPathFilterDialect" xmlns="http://schemas.xmlsoap.org/ws/2004/09/enumeration">/Person[(Department = '[//Target/ObjectID]')]</Filter>,Filter
The whole thing looks like this:
(I use Function evaluator to generate a AccountName for groups based on a clean version of DisplayName).
[//Target/DisplayName],DisplayName
SEC_[//WorkFlowData/CleanAccountName],AccountName
[//Target/Manager],Owner
Security,Type
DOMAIN_STRING,Domain
Universal,Scope
[//Target/DisplayName]_SecGroup,Description
[//Target/Manager],DisplayedOwner
None,MembershipAddWorkflow
True,MembershipLocked
[//Target/CleanAccountName],MailNickname
<Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Dialect="http://schemas.microsoft.com/2006/11/XPathFilterDialect" xmlns="http://schemas.xmlsoap.org/ws/2004/09/enumeration">/Person[(Department = '[//Target/ObjectID]')]</Filter>,Filter

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?

cd/ wrote:
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.

Rob.

LMS 2.6 dynamic groups with wildcards

Is is possible to build dynamic groups in RME using wildcards or regular expresions? The rules that I want to define would look similar to the following:
Device.System.Name StartsWith "SW" AND (
Device.System.Name contains "........X" OR
Device.System.Name contains "........Y" OR
Device.System.Name contains "........E" OR
Device.System.Name contains "........Z")
Where the device name begins with SW and there is either an X, Y, E or Z in the 8th position of the device name.

This is not possible. The ruleset matching is based only on the operators available for the given property.
The best workaround I can give you is to apply your first rule, then manually adjust the membership list based on the other rules. The downside of this is that the membership list would require modification when you add new devices.

DIP_LDAPWRITER_ERROR_CREATE
Error in executing mapping DIP_LDAPWRITER_ERROR_CREATE
DIP_LDAPWRITER_ERROR_CREATE
Please, note. Loading is successful if we commenting out mapping line for labeledURI attribute (that's loading static groups).
Loading is also successful when labeledURI is mapped to
'ldap://idm01.ic.lan:389/cn=DEV,cn=HRSyncUsers,cn=Users,dc=ic,dc=lan??sub?(objec
tclass=person)' but this definetly is not what we are going to get.
I don't have ideas what's wrong for example with the following generated 'labeledURI' attribute:
ldap://idm01.ic.lan:389/cn=DEV,cn=HRSyncUsers,cn=Users,dc=ic,dc=lan??sub?(departmentnumber=82)
Any help is appreciated
Thanks,

Hi Frank,
there is something wrong with departmentnumber attribute of user records. Searching users with ldapsearch using "departmentnumber=*" filter fails with the following error:
ldap_search: DSA is unwilling to perform
ldap_search: additional info: Function Not Implemented
I think this is probably the cause of failing creation of dynamic groups.
Searching on other user attributes (cn, uid, employyenumber) works fine.
Still don't understand what's wrong with this particular attribute.
