Select count(*) for each row of a table

Hello All,
Following query gives a statistics for each user (how many items he owns, home many tickets authored, how many objects he is subscribed to etc...)
select auser.userid,
(select count(*) from item where owner like '%' || auser.id || '%') ITEM_OWNER_CNT,
(select count(*) from tkt where originator = auser.id) TKT_ORIGINATE_CNT,
(select count(*) from tkt where assigned_to = auser.id) TKT_QA_CNT,
(select count(*) from tkt where create_user = auser.id) TKT_AUTHOR_CNT,
(select count(*) from subscriptions where subscriber_id = auser.id) SUBSCRIPTION_CNT
from
user auser
I was not happy with the performance of this query, so I tried the same using group by. The performance was even worse.
Is there any other option for me to try? Please advice.
Thanks,
Sathish

Hi, Sathish,
As SBH said, a lot depends on your data. Please post some sample data (CREATE TABLE adn INSERT statemetns) for all tables, and the results you want from that data. Describe and give examples of any relationships that are not one-to-one..
You probably want to do joings, like SBH suggested, rather than scalar sub-queries.
The connection between the auser and item tables
(select count(*) from item where owner like '%' || auser.id || '%') ITEM_OWNER_CNT,is very suspicious. Perhaps the item table is poorly designed, and the query would be faster if that table were changed. Is changing the design of the item table an option?
You should be able to get all the information from the tkt table in one pass. It looks like you need to unpivot the data, so instead of one row per ticket (with 3 different people connected to it), there are 3 rows per ticket, each with only 1 person referenced. This is not necessarily a bad table design. Unpivoting, even more than most other things, depends on your database version, so you'll have to tell what version of Oracle you're using.

Get the Count for each row

I'm trying to get the count for each row to total count for each month
Something like this
Hardware | Jan
Monitors | 5
Processors | 137
Printers | 57
etc........
How can I write a query for this. I can get the Hardware column but don't know how to get the next column.

If you can provide more data like sample input DML statements it would have been wonderful..
Assuming is , you need a pivot. Here is an article on basic Pivot..
http://sqlsaga.com/sql-server/how-to-use-pivot-to-transform-rows-into-columns-in-sql-server/
something like this may be..
DECLARE @Input TABLE
Hardware VARCHAR(20),
[Date] VARCHAR(20)
INSERT INTO @Input VALUES('Monitor', '01/01/2014'), ('CPU', '01/01/2014'), ('Monitor', '01/03/2014')
, ('ABC', '01/01/2014'),('Monitor', '02/01/2014')
;WITH CTE AS
SELECT Hardware, LEFT(DATENAME(M, [Date]),3) AS [MonthName] FROM @Input
SELECT *
FROM
SELECT Hardware, [MonthName], COUNT(Hardware) AS Count FROM CTE GROUP BY Hardware, [MonthName]) a
PIVOT (MAX([Count]) FOR [MonthName] IN ([Jan], [Feb])) pvt

Good Luck :) .. visit www.sqlsaga.com for more t-sql code snippets and BI related how to articles.

Different values in a list box for each row of the table control...

Dear Experts,
Is it possible to populate different values for each row in a listbox inside a table control ?
Example,
Row 1 in the the table contains A, B & C
Row 2 in the same table contains C, D & E
If yes, How?
yes i am using
call function 'VRM_SET_VALUES'
    exporting
      id     = i_name

Update primary key with a tabular form based on a select list for each row

Hello!
I've two tables: Table1 with only one column (primary key) is a foreign key for table2.column1 (primary key). There is also a second primary key column in table2.
Now I want to change the primary key values in table2.column1 with a tabular form (MRU) based on a select list (LOV based on table1.column1) for each row.
The user should be able to choose for every row a new value from the select list to change the old primary key value at this position.
How can I do this with ApEx?
I've the tabular form and so on, but at the moment I get the following error:
"Error in mru internal routine: ORA-20001: Fehler in MRU: row= 1, ORA-20001: ORA-20001: Die aktuelle Version der Daten in der Datenbank wurde geändert, seit der Benutzer einen Update-Prozess eingeleitet hat. ..."

For each row of a table call a pl/sql function

Hi,
i have a search form in adf like this:
parameter1:___
parameter2:____
buttonSearch
Table with results
field1 field2 field3
row1 ------ --------- -------
row2 ------ --------- -------
row3 ------ --------- -------
The user inputs the parameters 1 and 2 then press buttonSearch and the query execute and returns rows 1 to 3.
What i need is for each row call pl/sql function and passed the parameter 1 and 2 and field 1 to 3 (plsql function recives 5 parameters (parameter1, parameter2, field1 , field2 and field3) )
my buttonSearch call a java class that execute ExecuteWithParamters method.
I create the call to my plsql function on Application module class and then export as a java interface.
So i have the function to use in the viewcontroller layer, but i don't know where to use it, and how to pass the paramters: the parameter 1 and 2 that user inputs and the row fields.....
any ideas....
thanks!!

Hi,
for this you need to call the PLSQL function upon table rendering, which means that you need a field in the table referencing a managed bean. In the managed bean you can use #{row} and resolve it using a ValueExpression. #{row} gives you access to the current rendered row (this is why you need to do it when the table renders) and thus allows you to call getAttribute(name) to get the values of field 1 - 3. The search field value you should get through the bindings reference (assuming the search form uses ADF). Then you create an operation binding for the executeWithParameters and call operationBindingName.getParamsMap().put(argname, argvalue); on it.
Frank
Ps.: I am concerned about the performance you get and wonder if it isn't possible to create a transient attribute that executes the function and displays the results. As I understand, the search parameters are only to filter the result set, which you still can do

How to change VO's dynamically for a item for each row in advanced table?

Hi All,
We had a requirement to filter the employees based on the search criteria table. I am using advanced table for developing search criteria.
In that table I am having three columns. Operator (messagechoice), Criteria Type (messagechoice), and Criteria value (messageLovInput). Also 'Add Another Row' functionality is available.
My requirement is:
First Row:(Initial Row)
When the user selects a value in Criteria Type, only the values that are relevant to that type should be displayed in the Criteria Value.
Second Row: (when the user selects Add Another Row button)
When the user selects a value in Criteria Type, only the values that are relevant to that type should be displayed in the Criteria Value.
The problem I am facing here is, the Criteria Value column is pointing to only one VO at design time. But wee need to change that VO dynamically without disturbing other rows depending on the Criteria Type value.
Is it possible to do so?
Note: User can add n number of conditions as he want.
Can anyone help how to acheive this.
Regards,
Sundeep.

Condtion based xml for each row of the table t-sql

Hello ,
i have below data.
create table #students
id int identity(1,1) primary key,
student_id int not null,
[s_m_cml] xml
insert into #students
student_id,
[s_m_xml]
values
101,
'<submarks><submark><subject>Arts</subject><marks>85</marks></submark><submark><subject>Science</subject><marks>95</marks></submark><submark><subject>maths</subject><marks>100</marks></submark></submarks>'

select * from #students
if all subjects- marks in s_m_xml marks > 80 then i select the row as promoted else as demoted. the exact output should look like below.
student_id [status]
101 promoted
102 demoted
what is the best way to achieve this using t-sql. Thanks in advance for any suggestions.

You dont need to parse out the values from xml for this
You can do the check inline
see illustration below
drop table #students
create table #students
id int identity(1,1) primary key,
student_id int not null,
[s_m_cml] xml
insert into #students
student_id,
[s_m_cml]
values
101,
'<submarks><submark><subject>Arts</subject><marks>85</marks></submark><submark><subject>Science</subject><marks>95</marks></submark><submark><subject>maths</subject><marks>100</marks></submark></submarks>'
),(102,'<submarks><submark><subject>Arts</subject><marks>50</marks></submark><submark><subject>Science</subject><marks>75</marks></submark><submark><subject>maths</subject><marks>85</marks></submark></submarks>')
,(104,'<submarks><submark><subject>Arts</subject><marks>92</marks></submark><submark><subject>Science</subject><marks>88</marks></submark><submark><subject>maths</subject><marks>98</marks></submark></submarks>')
select *,
case when [s_m_cml].exist('/submarks/submark[data(marks) < 80]')=1 then 'demoted' else 'promoted' end as status
from #students

Create a counter for the rows in a table using script editor?

Hi ,
I want to add afield in a particular table with first field is its serial number . How to use scripting editor to fill the serial number ?
How to create a counter ?
Edited by: Rajan.Dexter9 on Jan 30, 2012 9:40 PM

Hello Rajan,
Create a field in the table and name it as 'SERIAL'. Create a variable called 'count' with default value as 0. Now in script editor, for javascript language and calculate event, write the following script.
var fields = xfa.layout.pageContent(xfa.layout.page(this)-1, "field", 0);
for (var i=0; i <= fields.length-1; i++)
     if (fields.item(i).name == "SERIAL")
          count.value = count.value + 1;
                 this.rawValue = count.value;

Count() for each group, but only groups having 1+ element like... AND all elements like...

There are tables(and columns) like:
'Clients'(clientID)
'Houses' (houseID)
'Visits' (clientID, houseID, visit_date)
'Contracts'(contractID, houseID, clientID, rentDate_from, rentDate_end)
I have problem with writing MS SQL query of this kind:
how many visits to houses did each client, before renting one of them?
Its easy to count total number of Visits for each client, listing all visits + group by clientID and selecting count(*) for each group.
Lets say this is select_1, and select_2 is listing all Contracts for all clients.
Select_1 is not answer, because count must be performed only on groups, which:
-have at least 1 row "like" row in select_2 (it means that at least one of visited houses was rented, because it can happen that client visited few houses, but rented other, not visited house). my idea for this is comparing select_1 and select_2 with:
"where s1.clientID=s2.clientID and s1.houseID=s2.houseID"
-each group must have all rows(visits) with date of same day or earlier than contract date
maybe: "datediff(day, s1.visit_date, s2.rentDate_from) >= 0"

In future, please provide proper DML, DDL and example data, like I have for you below.
DECLARE @clients TABLE (clientID INT, name VARCHAR(20))
INSERT INTO @clients (clientID, name)
VALUES (1, 'Jonathan'),(2, 'Christopher'),(3, 'James'),(4, 'Jean-Luc'),(5, 'William')

INSERT INTO @houses (houseID, address)
VALUES (1, 'NX01'),(2, 'NCC 1701'),(3, 'NCC 1071A'),(4, 'NCC 1701D'),(5, 'NCC 1701E')
DECLARE @visits TABLE (clientID INT, houseID INT, visitDateTime DATETIME)
INSERT INTO @visits (clientID, houseID, visitDateTime)
VALUES (1,1,'2001-01-01 12:13:14'),

DECLARE @contracts TABLE (contractID INT IDENTITY, houseID INT, clientID INT, rentStartDate date, rentEndDate date)
INSERT INTO @contracts (houseID, clientID, rentStartDate, rentEndDate)
VALUES (1,1,'2001-01-02',NULL),(2,2,'2001-01-02',NULL),(3,3,'2001-01-02',NULL),(4,4,'2001-01-02',NULL),(5,5,'2001-01-02',NULL)
SELECT contractID, c.houseID, c.clientID, rentStartDate, rentEndDate, cl.clientID, name, h.houseID, address, COUNT(v.clientID) AS visits
FROM @contracts c
LEFT OUTER JOIN @clients cl
ON c.clientID = cl.clientID
LEFT OUTER JOIN @houses h
ON c.houseID = h.houseID
LEFT OUTER JOIN @visits v
ON c.clientID = v.clientID

How to process a block for each row in an internal table....

Hi experts....
In po approval workflow the scenario is like this.... for each po there may be more than one approver. approvers list i am maintaining in the ztable. list of approvers(no of approvers) is decided by the po value. I have collected these approvers into internal table. now i have to process a block ( approving or rejecting the po... )in the workflow for each row in the internal table.
how can i do this. based on the decision of the 1st approver approves the po then it should go to next approver in the internal table...otherwise end the workflow.....
Please help me......

i have created an internal table in the workflow container in which i am getting the list of approvers....
how can i loop the internal table in the workflow...?
how can i know the index of the loop in the workflow.....(will sy-index work here....? so that i can use loop until step in the main workflow to call the subworkflow..so that if sy-index is greater than no of entires in the itab then i can come out of the loop)

Make select for each row - another solution?

For example I have a function with day before selection:

function ABS return boolean is
ret number(10,2);
begin
for sab in (select saldod from ndv_ccli, nd_clientes where
(:p_dtvenc-dtdoc) = (select min(:p_dtvenc-dtdoc) from ndv_ccli, nd_clientes
where (:p_dtvenc-dtdoc>0)and
ndv_ccli.cod_cli = cod_cli) and
ndv_ccli.cod_cli = cod_cli order by dtdoc desc,cddb )
loop
ret := sab.saldod;
end loop;
return (ret);
end;
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
In report I use the value of this function(a) in another function(b) to sum with few values.
Output of function(b) has a lot of rows and for each row it makes select in function(a) to find the value, but actualy it is the same. Is it possible to do this select only one time and then put in function(b) only it's value? Because it makes report too slow...
tnx before

Drop Down List in a table - different options for each row

How can i have a drop down list in a table with different options for each row?
My requirement is this.. I want to display, say employee dtails in a table, and one column is employee hobbies, whcih can have multiple values and each employee may have a different list of hobbies. So how can we populate the drop down for each row, with different options?

Hey. Uh, this probably isn't the answer you were looking for, but it sounds like you've got a problem with your database design there. Generally speaking, your tables shouldn't have multi-valued fields, in the relational model anyway (sql). Instead, you should look at adding a separate table like EMPLOYEE_HOBBIES. Then you have a foreign key using the employees primary key as the foreign key in the employee_hobbies table, see what I mean? I might have misunderstood your explanation though, I'm not sure.
Alternatively, you could just have hobbies as a big freeform varchar field, and don't bother to make people separate their hobbies into different fields (you'd have to abandon the drop-down listbox idea in this case). If there's no really important reason to make the distinction, then it's probably easier just to not do it.

Updating A Table in a for each row trigger

I have a trigger,
create or replace trigger ins_ibpm_temp_trig
after update of ethic_dt on ethics_approval_info for each row
My issue is that I need to update the ethics_approval_info for each record based on the ethics date that was updated. I am getting the error
ORA-04091: table ORACLETEST.ETHICS_APPROVAL_INFO is mutating, trigger/function may not see it.
So the issue here of course is that I am trying to update a table, that is already in the middle of updating. Is there any way to get around this?

Check Box for each row in report -- all rows deleting when pressing DELETE

Hello experts! I have set up a report with a check box for each row. When I click the DELETE button to delete the selected rows, every single one of the rows get deleted...even the ones that are not selected. I have my process point set to "On Submit - After computations and validations".
This is my delete process (SHG is the table and SHG_ID is the primary key):
FOR i in 1..HTMLDB_APPLICATION.G_F01.count
LOOP
DELETE FROM SHG
WHERE SHG_ID = HTMLDB_APPLICATION.G_F01(i);
END LOOP;
Also, I've added to query in the region source this line:
htmldb_item.checkbox(1, SHG_ID) del,
Where does the "1" come into this? Not sure what I am doing wrong!

The 1 (first argument to all the htmldb_item.* APIs) corresponds to the array number in htmldb_application.g_fNN. So 1 will populate array g_f01, 2 will populate g_f02 and so on.
Your code seems fine, it should delete only the checked rows. Are you sure there is no other process on the page that might be deleting the rows? See if you can put up an example on htmldb.oracle.com
