Multiple SELECTS or one Procedure to generate Count Statistics?

I've got an application showing purchases from a catalog. I
need to show statistics on those purchases -- the number of
buyers by product by month, the number of buyers by source
(space ads, direct mail, telephone, online) by month, the number
of buyers by state by month, etc. In other words, there are a
lot of row counts to generate.
The question is, am I better off creating an SQL statement for
each count request, or, since I have so many counts to generate,
am I better off writing an SQL Procedure to loop through all the
rows with a single table scan and update tables with the counts?
An example count request -- counts by product code by month:
SELECT TO_CHAR(purchdate, 'YYYYMM'), prodcode, count(*)
FROM transactions
GROUP BY TO_CHAR(purchase,'YYYYMM'), prodcode
Oracle is pretty good at optimizing SQL, and it's certainly
easier to focus on each SQL statement one at a time. But, it
will require many full-table scans (and/or many indexes). The
Procedure route is much more difficult to write in a general way
(since I really have 30 or 40 different tables to do these
statistics on with different columns to count in each table,
with more coming in all the time).
One more bit of info -- these counts are only generated after
the file is updated. These updates are done monthly or
quarterly, so these counts are not run all the time and are not
generated on demand. We save them as PDF files for viewing.
Any advice is greatly appreciated! :-)
PS. I currently do this using Oracle Reports. This ends up as
the "one SQL statement per count" method. But, I've just gotten
a file in with 4 million records, and I don't want to wait until
next year for the report to finish! :-)

Dear Mr. Nagrajan,
Thank you for your response. I have already gone through documents but not able to understand. Is there any setup for this ? or its just work around i.e. using template and special field in JV i.e. Ref. 1 /2
My doubts :
I understand that Chart of Account structure is one and common for IFRS and other accounting method. We need to create only those account separately ( 2 times with prefix like IFRS revenue account, GAAP Revenue account).
Now at time of entry, Assume some entries / adjustment are specifically for IFRS and not for other ledger. In this case, What need to do ?
You have mentioned about DTW approach but do we need to insert all JV's again with other ledger ?
Someone suggested that if any entry which are specific to IFRS Ledger, We need to user Ref.1 /2 column or Transcation code column and in which we can put IFRS
Based on this, Need to create 2 seperate template for IFRS and other ledger for all report.
This is my understanding of Solution in SAP B1. Please help me to clarify my though process
Please do needful.If you have done implemenation and if you can share doucment, it would be great help.

Return multiple cursors from one procedure

Hi,
I have a stored procedure that is suposed to return multiple records. I know that for each table that I return I have to add a param to the stored procedure, param with ref cursor type.
I do not know exactly how many tables I have to return, it depends on data from some tables.
Is it possible to return an unknown number of tables? like an array or something ...
Please help

In order to keep it transparent to the developer, I have to translate exactly the stored procedures from SQL Server to Oracle.Well "exactly" is not something that you are going to achieve. You're talking about two disperate languages. That's like saying you want to translate French to English, but it must stay French.
You obviously want to mimick the existing functionality, but in some cases you're just going to have to bite the bullet and accept that you won't be able to do it totally transparently. In this case, the developers are going to have to make some changes at their end of things too.
To translate the procedures from T-SQL to Oracle was
the easiest and most convenient option to the
developers, so they will not have to write different
code for Oracle and SQL.But they will. Anyone who evaluated the project and determined that the developers wouldn't need to do anything when moving from one platform to another should be sacked for incompetence.

SQL multiple selects in one report?

Hello,
I'm having a problem selecting from the following table (let's call it the dpt_user_role) to be able to create a custom report,
The table looks like the following:
Dpt_id User_id User_is_manager
1 1001 N
1 1002 Y
1 1003 N
2 1001 Y
2 1005 N
2 1006 N
3 1001 Y
3 1007 N
3 1008 N
I would like to build a custom query to fit in just one report that would give me the following results for user_id 1001
Dept_id User_id User_is_manager
2 1001 Y
2 1005 N
2 1006 N
------ (line from the custom report template separating dpts) ------
3 1001 Y
3 1007 N
3 1008 N
As you can see I need to select all the depts where user_id :PX_USER is a manager but also the non manager users in that report.
Any help pointing me in the right direction will be greatly appreciated and sorry for the inconvenience.
Thanks.
Best regards,
NJ

Hello,
Thank you for your fast answers and for helping.
The result of the query returns,
2 1001 Manager
2 1005 Non-Manager
2 1006 Non-Manager
------ (line from the custom report template separating dpts) ------
3 1001 Manager
3 1007 Non-Manager
3 1008 Non-Manager
But I really need something like
Dept_id Manager User_is_manager
2 1001 Y
Dept_id Non-Manager User_is_manager
2 1005 N
2 1006 N
------ (line from the custom report template separating dpts) ------
Dept_id Manager User_is_manager
3 1001 Y
Dept_id Non-Manager User_is_manager
3 1007 N
3 1008 N
So I could pass the results to the custom report like
[begin of template report]
Manager of Dept #Dept_id# is #Manager#
Non managers users are #Non-Manager#
------ (line from the custom report template separating dpts) ------
[end of template report]
And the report would go to Dept_id = 3 and so on. I would have to perform an inner join of some sort to get the Manager and Non-Manager users first and last names from a different table.
Is this all possible in a single query or am I in hyperspace here?
May the good winds of fortune keep blowing your way and inspiring you.
Thank you!
Best regards,
NJ

Insert items from two different Multiple Select Lists into a single table

I need help. I have a training tracking system that tracks the courses taken by employees.
I have created two multiple select lists, one is SelectEmployees and the other is SelectCourses. I want to insert
the selected item from those two multiple select lists into Training_Record table.
Note, SelectEmployees" is from Employee table and SelectCourses is from Courses table. Those two table has no intersetion.
Train_Record is the table that joins those two together.
Please advice and your help is appreciate.

Thank you for your help.
I tried your code and changed the table/field name to my actual table/field name and the iitem name to actual item name.

Multiple Selections

I am following a tutorial which calls for multiple selections on one layer as seen here:
http://www.pixentral.com/show.php?picture=10OuFfXZsVAdtugJaVg26Thjv0EJr0
Is it possible to do this in Elements, as the selections don't intersect?
I did a work-around be copying each selection to a new layer, then merging the layers. Perhaps the tutorial requires full Photoshop for execution.

For every tool that you select, the options are displayed in the options bar which is the horizontal bar at the top of the application UI below the menu bar. When you select any selection tool, there are four small thumbnails at the right of the options bar which function as follows in order from left to right-
Simple selection(previous selection will be discarded whenever you make a new selection.
Add to selection(You can make multiple selections)
Subtract from selection (All the areas that you select after the forst selection you make ,will be removed from your selection.)
Intesection og selections.
From amomgst these, you need the second options.
Cheers!!

Multiple selection of rows in table

HI,
can any one tell how to dispaly the rows selected(multiple selection) in one table can be displayed in another table in 2nd view.
Regards,
A.K

Hi,
1.Iterate through the node bound to the table
2 Add the selected elements to a List.
3.bind this list to a node
4.Bind this node as the datasource for the second table.
Ex:
ArrayList selectedElements = new ArrayList();
for (int x=0; x< wdContext.nodeTest().size(); x++)
if( wdContext.nodeTest().isMultiSelected(x) )
// Selected Element
IWDNodeElement nodeElement = wdContext.nodeTest().getElementAt(x);
selectedElements.add(nodeElement)
wdContext.nodeSeondNode().bind(selectedElements);

Generate Multiple Invoices in One PDF

Hi,
I have requirement whereby I need to generate multiple invoices in one PDF file. I am using Oracle BI Publisher with Oracle APEX 4.0.2
If there is only one invoice that needs to be generated in one PDF file then I already have the solution whereby I print the APEX page item session state values on Invoice Header and get the invoice line items from a SQL Query in my RTF template.
However how to the do the same when multiple invoice needs to be generated in one single PDF file ?
Any pointers will highly appreciated.
Thanks & Regards,
Ashish

asagarwal wrote:
However how to the do the same when multiple invoice needs to be generated in one single PDF file ?It should be pretty straight forward.
Once you've got the query returning multiple rows, then just add a repeating group to your report (if an existing report, just select the section of the document that will repeat -> add-ins menu -> insert repeating group...; or right click selection -> BI Publisher -> Create group...), wherein the column values exist. You can even specify a page break at the end.
By the way, this question is probably more suited for the {forum:id=245} forum.

Executing a stored procedure containing multiple Select statements

Post Author: Beverly
CA Forum: General
I am using Crystal 10.0 against a MS SQL 2000 server.
I am trying to create a report based on a stored procedure that contains multiple select statements. The sp requires a single parameter (Claim number) and contains 17 Select statements that produce results.
I am able to use the Add command and execute the sp with the parameter, but I am only getting the results of the first select statement in the sp back in my data set. Is there a way to have the data from each Select statement returned to my report?
I have used Crystal for a while, but pretty much for straight-forward reporting. I am familiar with the basics of SQL.
I would appreciate any help anyone can offer.
Thanks.

Post Author: BISoftware
CA Forum: General
I believe Crystal Reports can only handle one recordset at a time, which means it can only handle a single select statement. The only way I can see around this would be to break up your stored procedure into multiple stored procedures, so that each only contains a single select statement. Then, use subreports to report on each individual sp. Hope this helps. - Davewww.BusinessSoftwareResource.com

JDBC Sender MSSQL Stored Procedure - Multiple Select Statements

Hello all,
I will proceed to tell you my problem, for which solution I request your kind advice:
Im working in a project for a retailer, which consists in sending the information from erp and sql server to pos thru XI interfaces.
One of the interfaces is about sending items from sql server to a file so the pos can load it into the system. For doing so I have devloped an stored procedure which function is to return several select statements as many stores the retailer might have, so they can have a different file per store along with its corresponding items in it.
The thing is that XI just gets the first select statement and creates the corresponding file, but it seems to ignore the remaining responses as I'm neither getting any file nor an error afterwards.
So, my question is: is XI capable of handling multiple select responses from an Stored Procedure in graphical mapping??? Or am I just wasting my time trying?
Thanks in advice for your help.
Regards.

Hello Ramkumar,
After 5 days trying, I finally made it work out applying your advice. Below the short explanation of what I did:
My Source structure is: Main Node->Row->Records (Material Number, StoreNum, Price, Status)
My Target structure is: Main Node->File Node->Record Node->Records ( Material Number, Price, Status)
The key was to make all the occurrences happen against StoreNum node. So, based on what you adviced these two where the key mappings:
1) The Mapping that will create a new file for each different store that comes in the query (In my case, query was already sort by store using an sql "order by" function, if not you can also use xi node function "sort" as Ramkumar suggested)
StoreNum->RemoveContext->SplitbyValue (Value Changed)->Collapse Contexts->File Node
2) The Mapping that will create each record in its corresponding store file:
StoreNum->RemoveContext->SplitbyValue (Value Changed)->Record Node
And Voilá !!! It worked.
Thanks very much Ramkumar.
Regards.

Multiple Select boxes in one form

Does anyone know if it is possible to have multiple select
boxes inside one form? I have six different select boxes that are
generated by six separate queries. The action page for all six
select boxes is the same so I just want one submit button so users
don't get confuse. I don't want to cluster up the page with submit
buttons but I may resort to that option.
My problem is the select boxes generate a number and when
that number is submitted I want to pass two other variables with it
to the action page. I tried putting a "Form" tag around the 6
select boxes. Inside each select box I tried to add an "Input
type="hidden"" and give thte name and values that I needed. That
worked for the first select box but when I tried the second select
box it used the hidden values for the first select box.
If anyone can help, I would greatly appreciate it. Or if you
have any other suggestions I am open to any.
Thanks

Paross1,
I wasn't thinking about that and you gave me a great idea.
Here is how I changed my select boxes.
<cfform
action="Resolution_History.cfm?year=#year#&sessiontype=#sessiontype#&btype=res"
name="form">
<select name="SRINPUT">
<option value="">SR
<CFOUTPUT Query="findSR"><Option
Value="#BILLNUMBER#">#BILLNUMBER#</cfoutput>
</select>
<select name="HRINPUT">
<option value="">HR
<CFOUTPUT Query="findHR"><Option
Value="#BILLNUMBER#">#BILLNUMBER#</cfoutput>
</select>
<select name="SCRINPUT">
<option value="">SCR
<CFOUTPUT Query="findSCR"><Option
Value="#BILLNUMBER#">#BILLNUMBER#</cfoutput>
</select>
<br>
<select name="HCRINPUT">
<option value="">HCR
<CFOUTPUT Query="findHCR"><Option
Value="#BILLNUMBER#">#BILLNUMBER#</cfoutput>
</select>
<select name="SJRINPUT">
<option value="">SJR
<CFOUTPUT Query="findSJR"><Option
Value="#BILLNUMBER#">#BILLNUMBER#</cfoutput>
</select>
<select name="HJRINPUT">
<option value="">HJR
<CFOUTPUT Query="findHJR"><Option
Value="#BILLNUMBER#">#BILLNUMBER#</cfoutput>
</select>
<INPUT TYPE="Submit" VALUE="Submit" alt="submit
button">
</cfform>
On the action page I need the below IF statement to work so
it will set the variables. It isn't working at this time. Its not
bringing the values of billnumber, houseorig or the billtype.
Do you have any thoughts? I know it is close. I need to set
all of the inputs to input4 to generate my queries.
<cfif form.srinput gt 0>
<cfset houseorig eq "s">
<cfset billtype eq "r">
<cfset srinput eq input4>
<cfelseif form.hrinput gt 0>
<cfset houseorig eq "h">
<cfset billtype eq "r">
<cfset hrinput eq input4>
<cfelseif form.scrinput gt 0>
<cfset houseorig eq "sc">
<cfset billtype eq "r">
<cfset scrinput eq input4>
<cfelseif form.hcrinput gt 0>
<cfset houseorig eq "hc">

<cfset hcrinput eq input4>
<cfelseif form.sjrinput gt 0>
<cfset houseorig eq "sj">
<cfset billtype eq "r">
<cfset sjrinput eq input4>
<cfelse>
<cfset houseorig eq "hj">
<cfset billtype eq "r">
<cfset hjrinput eq input4>

How to return the result set of multiple select statements as one result set?

Hi All,
I have multiple select statements in my stored procedure that I want to return as one result set
for instance
select id from tableA
union
select name from table b
but union will not work because the result sets datatypes are not identical so how to go about this ?
Thanks

You have to CAST or CONVERT (or implicitly convert) the columns to the same datatype. You must find a datatype that both columns can be converted to without error. In your example I'm guessing id is an int and name is a varchar or nvarchar.
Since you didn't convert the datatypes, SQL will use its data precedence rules and attempt to convert name to an int. If any row contains a row that has a value in name that cannot be converted to an int, you will get an error. The solution is
to force SQL to convert the int to varchar. So you want something like
select cast(id as varchar(12)) from tableA
union
select name from tableb
If the datatypes are something other that int or varchar, you must find a compatable datatype and then convert one (or both) of the columns to that datatype.

Generating multiple rows from one physical row

I was wondering if anyone has done or knows how to generate multiple rows for one physical row. In my query "SELECT Cust_No, Amount from Balances" if the amount is > 99,999.99 I want 2 rows returned, one with an amount of 90,000.00 and the other with an amount of 9,999.99. I'm thinking I need to use a view or function to return a result set but I'm not sure how.
Thanks in advance,
Allen Davis
[email protected]

James,
Well your right in that you need a function, but also 3 views to accomplish that. I just wrote up the sql below and tested it. Basically you want the first view to return all records less than your cap of 99,999, thoes that exceed that will always return as 90,000 (see example on record PK 774177177). The second view returns money that remains AFTER the cap (in your case 9,999). The second view though also has to excude the ones less than the CAP.
DATA and TABLE layout
1) Table is called T1, columns are PK : primary key value, and N2 : some number column holding the MONEY amount
2) data is below fromtable called t1 (10 records) ...
select pk,n2 from t1 order by pk
PK     N2
117165529     100
274000876     200000
350682010     9999
737652242     90000
774177177     99999
1369893126     1000
1663704428     100000
1720465556     8888
1793125955     0
1972069382     1000000
Now see the records with money at 99,999 (just like in your example). You want 2 records, so the VIEWS now come into play. The view itself CALLS the function, this occurs when you select from the view. The function will either return 90,000 (your defined cap) or the remained after subtracting the money from 90,000. The 3 views are defined below (the FUNCTION which is shown after will have to be compiled first) ...
--[VIEWS START]
CREATE OR REPLACE VIEW VIEW1
(PK,SHOW_MONEY)
AS SELECT PK,FN_TRIM_MONEY(N2,1) FROM T1;
CREATE OR REPLACE VIEW VIEW2
(PK,SHOW_MONEY)
AS SELECT PK,FN_TRIM_MONEY(N2,2) FROM T1 WHERE N2 >= 99999;
CREATE OR REPLACE VIEW VIEW_ALL
(PK,SHOW_MONEY)
AS
SELECT * FROM VIEW1
UNION ALL
SELECT * FROM VIEW2;
--[VIEWS END]
OK now for the actual function ...
--[FUNCTION START]
CREATE OR REPLACE FUNCTION
FN_TRIM_MONEY
PI_MONEY NUMBER,
PI_VIEW_ID NUMBER
RETURN NUMBER AS
LS_TEMP VARCHAR2(2000);
LI_TEMP NUMBER;
LD_TEMP DATE;
LI_CON_MONEY_MAX CONSTANT NUMBER := 90000;
LS_RETURN VARCHAR2(2000);
BEGIN
IF (PI_MONEY > LI_CON_MONEY_MAX) THEN
IF PI_VIEW_ID = 1 THEN
LI_TEMP := LI_CON_MONEY_MAX;
ELSIF PI_VIEW_ID = 2 THEN
LI_TEMP := (PI_MONEY - LI_CON_MONEY_MAX);
END IF;
ELSE
LI_TEMP := PI_MONEY;
END IF;
IF LI_TEMP < 0 THEN
LI_TEMP := 0;
END IF;
LS_RETURN := LI_TEMP;
RETURN LS_RETURN;
END;
SHOW ERRORS;
--[FUNCTION END]
I compiled the function and views with no errors. This is what I get when I query the 3 views ...
--[VIEW 1]
PK     SHOW_MONEY
117165529     100
274000876     90000
350682010     9999
737652242     90000
774177177     90000
1369893126     1000
1663704428     90000
1720465556     8888
1793125955     0
1972069382     90000
--[VIEW 2]
PK     SHOW_MONEY
274000876     110000
774177177     9999
1663704428     10000
1972069382     910000
--[VIEW ALL]
PK     SHOW_MONEY
117165529     100
274000876     90000
274000876     110000
350682010     9999
737652242     90000
774177177     90000
774177177     9999
1369893126     1000
1663704428     90000
1663704428     10000
1720465556     8888
1793125955     0
1972069382     90000
1972069382     910000
So notice the PK entry 774177177 listed twice, once with 90,000 and other with 9,999. Also notice we now have 14 records from the original 10, meaning 4 records qualified for the split (all data from VIEW 2).
This is why Oracle kicks ass, views and functions are very powerful when used together and can return pretty much anything.
Thanks,
