Hi Experts,
How do I get the count of the rows in a table control during run time.

The easiest way to do this: set a default value for the sort column in your backing bean.
Example:
     private String sortColumn="firstName";
     public String getSortColumn() {
          return sortColumn;
     <t:dataTable sortColumn="#{yourBean.sortColumn}" ... />On page load, the arrow is set by default to the firstname column.

Need to get the count based on the column availability

You get a set of table names from a query, say
select table_name from all_tab_columns where column_name like 'DC_I’;
TABLE_NAME
A
B
C
Now, for the above set of tables (A,B and C), you need to get the count(*) for a single dc_i value (say XXX DC)
In simple words, its like framing the following 4 separate queries into one single one:
select table_name from all_tab_columns where column_name like 'DC_I’; (Based on this o/p, following 3 queries..)
select count(*) from A where dc_i=XXX;
select count(*) from B where dc_i=XXX;
select count(*) from C where dc_i=XXX;

To get the count of records and able to access the column value in a single

Hi
Is there any way to get the number of records in the query and access the column values
e.g
select count(*)
from
(SELECT department, COUNT(*) as "Number of employees"
FROM employees
WHERE salary > 25000
GROUP BY department ) a
This wil only get the Count, if i want to access each row from the inline view how can i do that.

Your question is not clear.
Are you looking for total record count as well as count by department ?
Something like this?
SQL>
SQL> with temp as

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
Please mark as answer, if this has helped you solve the issue.
Good Luck :) .. visit www.sqlsaga.com for more t-sql code snippets and BI related how to articles.

How to get the Count of a logic?

Hi,
Very new to CRM. I am trying to get the count of "activity start time" that are greater than current time stamp. Count(activity start time) work. I don't know how to add the time stamp condition to this. I can't add this condition as filter.
Appreciate any responses.
Thanks

Raghu,
Thanks for the help. It works to get the count.
The problem is, i have some other filters set and can't combine this filter. Here is my scenario:
get all activities on a contact that have greater than x $ amount as assets. I need to find the number of future appointments for that contact and start time of first pending future appointment. All has to be in one report.
My columns are for example : contact name, activity start time, end time, subject, next pending appointment start time, total future appointments, some other related fields from contact
So when I add the filter that you had given, it will not give me all activities. I am able to achieve all this in seperate reports and unnable to get it in single one.
Thanks,
GiGi

How to get the number of columns in a result set???

hi everyone..
i am trying to establish a servlet applet communication....
my applet send the sql query to the servlet as serialised string and then the servlet executes the query...
Since i need to pass the result back to the applet, i thaught of passing the whole reult set to the applet..but that seems to be not possible..
so i thaught of storing my result set data in a vector and then pass the vector,but the first problem that i came across is that how to get the number of colums in a result set....
so is there a way to get the number of columns in a result set...???
and also i would like to know if it possible to send my whole result set to the applet bye serialization or by any method...???
thanx in advance

You shouldn't do. It expenses resources (you should always close the ResultSet and the Statement as fast as possible). Simply gently process it into a Collection or Map of DTO's. Those are serializable.

How to get the count of customers

Hi all,
We have a fact table, AR_F to which the dimensions Party_D and Fin_D are connected. Party-org_d is inturn connected to Party_d.
party_org_D contains details of customers like Customer name and customer ID (Number)
Fin_D contains ratings (Both -ve and +ve) of each customer.
the rating range is as follows,
good rating : >0
OK Rating: Between 0 and -1.5
Bad Rating: <-1.5
Now i need to get the count of all customers falling in each range as separate measures.
Kindly help me get a solution for this.
Thank you.

Hi,
Try this....
col 1
case when Fin_D.ratings > 0 then 'Good'
when Fin_D.ratings >= -1.5 and Fin_D.ratings <= 0 then 'Ok'
when Fin_D.ratings < -1.5 then 'Bad' end
col 2
case when (case when Fin_D.ratings > 0 then 'Good'
when Fin_D.ratings >= -1.5 and Fin_D.ratings <= 0 then 'Ok'
when Fin_D.ratings < -1.5 then 'Bad' end)='Good' then count(customer_id)
when (case when Fin_D.ratings > 0 then 'Good'
when Fin_D.ratings >= -1.5 and Fin_D.ratings <= 0 then 'Ok'
when Fin_D.ratings < -1.5 then 'Bad' end)='Ok' then count(customer_id)
when (case when Fin_D.ratings > 0 then 'Good'
when Fin_D.ratings >= -1.5 and Fin_D.ratings <= 0 then 'Ok'
when Fin_D.ratings < -1.5 then 'Bad' end)='Bad' then count(customer_id)
end

How to get the count of each minutes

Oracle 10 DB
Hi All
I using this query to get the count of records fetched by the concurrent program per min,
select count (distinct b.attribute2)
from oe_order_headers_all a,oe_order_lines_all b
where a.header_id=b.header_id
and b.flow_status_code ='AWAIT_QUINTIQ_BOOK'
and to_Char(b.last_update_date,'DD-MON-YYYY HH24:MI:SS') between '19-JAN-2011 02:00:01' AND
'19-JAN-2011 02:00:02'
This is used to get the count of records fetched at one mins
How to find the count of last 10 mins ie 1 mins count 2.00 to 2.10
Thanks & Regards
Srikkanth.M

Try this:
SELECT TRUNC(b.last_update_date, 'mi') time_mins, COUNT(DISTINCT b.attribute2)
FROM   oe_order_headers_all a,
       oe_order_lines_all b
WHERE a.header_id = b.header_id
AND    b.flow_status_code = 'AWAIT_QUINTIQ_BOOK'
AND    b.last_update_date >= to_date('19/01/2011 02:00:00', 'dd/mm/yyyy hh24:mi:ss')
AND    b.last_update_date < to_date('19/01/2011 02:10:00', 'dd/mm/yyyy hh24:mi:ss')
GROUP BY TRUNC(b.last_update_date, 'mi');I'm not sure why you're bothering with the join to the oe_order_headers_all table, since you're not referencing that in the where clause or the selected columns list. I think you could probably do away with it.
I've changed your code to take the last_update_date and truncate it to the minute level, and added that as a column, so you can see which count goes with which minute. Obviously, this has to be in the group by.
I've also changed your date comparisons so that you're actually comparing dates to dates, rather than strings to strings - why would you deliberately take information away from the optimizer? Oracle does not treat strings the same as dates, and forcing it to use strings rather than dates could lead you to have a vastly differing execution path, which will most likely be less performant.
Not to mention, coding like that leads you to assume that you can compare dates in strings without any problems, and that is just not the case. '19-FEB-2011' is counted as being earlier than '19-JAN-2008', as strings sort alphabetically.

Sql statement to get the count of items in a group.

i have a table as follows
group id   items
   1            item1
   1            item2
   1            item3
   2            item4
   2            item5
i need to get the count of items for each group
the out put should be like
group = 1 count = 3
group = 2 count = 2
i wrote the following query
select   group count( * )
   into     (group , lv_count)
from     table1
group by group.
endselect.
is it possible to write this query without using end select.
when i am using the same query with into table addition the count is not coming.

Hi,
It will work, I tested just now, ofcourse with some other table.
Like this:
select group count( * )
INTO TABLE ITAB
from table1
group by group.
