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.

How to get the count of items(folders or documents) in a SharePoint document library and for a folder in any SharePoint document library?

I need to get a count of documents and folders in a selected document library(the item for EventRecievers for event deleting) and the count of documents in a selected folder(the item for EventRecievers for event deleting) to determine whether the item(document
library or folder) is empty or not, as I need to use this condition for one of my custom EventReceivers.
Can you please suggest me the code to do the same?

Hi.
Try this:
class Program
static void Main(string[] args)
using (SPSite site = new SPSite("http://z2012net"))
using (SPWeb web = site.OpenWeb())
SPList l = web.Lists["List001"];

SPQuery query = new SPQuery();
query.Folder = sPFolder;
res.Add(new FolderInfo() { ItemCount = sPFolder.ItemCount, Name = sPFolder.Name, Url = sPFolder.Url });
SPListItemCollection items = sPFolder.ParentWeb.Lists[sPFolder.ParentListId].GetItems(query);
foreach (SPListItem item in items)
if (item.FileSystemObjectType == SPFileSystemObjectType.Folder)

Thanks Billy, Would you be able to suggest any other faster method to load the data into table. Thanks,
As Mark responded - it all depends on the actual data to load, structure and source/origin. On my busiest database, I am loading on average 30,000 rows every second from data in external files.
However, the data structures are just that - structured. Logical.
Having a data structure with 100's of fields (columns in a SQL table), raise all kinds of questions about how sane that structure is, and what impact it will have on a physical data model implementation.
There is a gross misunderstanding by many when it comes to performance and scalability. The prime factor that determines performance is not how well you code, what tools/language you use, the h/w your c ode runs on, or anything like that. The prime factor that determines perform is the design of the data model - as it determines the complexity/ease to use the data model, and the amount of I/O (the slowest of all db operations) needed to effectively use the data model.

I created an Execute SQL Task in ssis package to get the counts and store it in the variable and I use the variable in the control flow

I always get the count as 0 for the variable. I am not sure what I am doing wrong. Please let me know if any of you know the fix.
Thanks

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.

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
2 (
3 select 1 dept ,10000 sal from dual union
4 select 1 dept ,25100 sal from dual union
5 select 1 dept ,30000 sal from dual union

Select Count(*) from Sample_table - how to get the count using JDBC?

Hi All,
It would be glad if anyone could help me with this. The problem is that I have to get the 'count' of records selected from a arbitrary table say, 'sample_table'. Is that possible to form the SQL in JDBC as
Select Count(*) from Sample_table
and get the value of the count? If yes, how?
Thanks in advance
Prabz

stmt = con.createStatement();
ResultSet recordcnt_rs = stmt.executeQuery("Select Count (*) as record_ctr From Sample_table");
recordcnt_rs.next();
record_ctr = recordcnt_rs.getInt("record_ctr");
hope this helps.

Use SQL function to get the original order number using the invoice number

Hi All,
wondering is someone can help me with this challenge I am having? Often I need to return the original order numbers that created the resulting invoce. This is a relatively simple seriese of joins in a query but I am wanting to simplify it using a SQL function that can be referenced each time easily from with in the SELECT statement. the code i currently have is:
Use SQL function to get the original order number using the invoice number
CREATE FUNCTION dbo.fnOrdersThatMakeInvoice(@InvNum int)
RETURNS nvarchar(200)
AS
BEGIN
DECLARE @OrderList nvarchar(200)
SET @OrderList = ''
SELECT @OrderList = @OrderList + (cast(T6.DocNum AS nvarchar(10)) + ' ')
FROM OINV AS T1 INNER JOIN
      INV1 AS T2 ON T1.DocEntry = T2.DocEntry INNER JOIN
      DLN1 AS T4 ON T2.BaseEntry = T4.DocEntry AND T2.BaseLine = T4.LineNum INNER JOIN
      RDR1 AS T5 ON T4.BaseEntry = T5.DocEntry AND T4.BaseLine = T5.LineNum INNER JOIN
      ORDR AS T6 ON T5.DocEntry = T6.DocEntry
WHERE T1.DocNum = @InvNum
RETURN @OrderList
END
it is run by the following query:
Select T1.DocNum, dbo.fnOrdersThatMakeInvoice(T1.DocNum)
From OINV T1
Where T1.DocNum = 'your invoice number here'
The issue is that this returns the order number for all of the lines in the invoice. Only want to see the summary of the order numbers. ie if 3 orders were used to make a 20 line inovice I only want to see the 3 order numbers retuned in the field.
If this was a simple reporting SELECT query I would use SELECT DISTINCT. But I can't do that.
Any ideas?
Thanks,
Mike

Thanks Gordon,
I am trying to get away from the massive table access list everytime I write a query where I need to access the original order number of the invoice. However, I have managed to solve my own problem with a GROUP BY statement!
Others may be interested so, the code is this:
CREATE FUNCTION dbo.fnOrdersThatMakeInvoice(@InvNum int)
RETURNS nvarchar(200)
AS
BEGIN
DECLARE @OrderList nvarchar(200)
SET @OrderList = ''
SELECT @OrderList = @OrderList + (cast(T6.DocNum AS nvarchar(10)) + ' ')
FROM OINV AS T1 INNER JOIN
      INV1 AS T2 ON T1.DocEntry = T2.DocEntry INNER JOIN
      DLN1 AS T4 ON T2.BaseEntry = T4.DocEntry AND T2.BaseLine = T4.LineNum INNER JOIN
      RDR1 AS T5 ON T4.BaseEntry = T5.DocEntry AND T4.BaseLine = T5.LineNum INNER JOIN
      ORDR AS T6 ON T5.DocEntry = T6.DocEntry
WHERE T1.DocNum = @InvNum
GROUP BY T6.DocNum
RETURN @OrderList
END
and to call it use this:
Select T1.DocNum, dbo.fnOrdersThatMakeInvoice(T1.DocNum)
From OINV T1
Where T1.DocNum = 'your invoice number'

How to get the count of all the entries in the DB?

Hello,
Yes, depending on the type of database you are using, the
following statistics from DB->stat, look like what you want.
For Hash databases:
hash_ndata;
The number of key/data pairs in the database. I
For Btree databases:
bt_ndata;
For the Btree Access Method, the number of key/data pairs
in the database.
For the Recno Access Method, the number of records in
the database.
For Queue databases:
qs_ndata;
The number of records in the database.

Getting the count of DISTINCT of several columns

How can i get the count of DISTINCT of several columns?
SQL> select count(distinct ename) from emp;
COUNT(DISTINCTENAME)
14
SQL> select count(distinct ename, job) from emp;
select count(distinct ename, job) from emp
ERROR at line 1:
ORA-00909: invalid number of arguments

Hello,
You should separate them out like this
select count(distinct ename), count(distinct job) from emp;Regards

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;
Thanks
