Help With SELECT Query With COUNT

Jun 11, 2008

Here's my tables:

-------------------------------------------------------
tblMembers
-------------------------------------------------------
MemberID | CountryID
-------------------------------------------------------


-------------------------------------------------------
tblCountries
-------------------------------------------------------
CountryID | CountryName
-------------------------------------------------------


-------------------------------------------------------
tblOrders
-------------------------------------------------------
OrderID | MemberID | OrderTypeID
-------------------------------------------------------


-------------------------------------------------------
tblSubscriptionOrders
-------------------------------------------------------
SubscriptionOrderID | OrderID | SubscriptionPackID
-------------------------------------------------------


-------------------------------------------------------
tblSubscriptionPacks
-------------------------------------------------------
SubscriptionPackID | TypeID
-------------------------------------------------------



Here's what I'm trying to do:
1. Output each country in one column
2. Output the number of subscriptions made from a member of that country where tblOrders.orderTypeID = 3 and tblSubscriptionPacks.TypeID = 1 in the next column
3. Output the number of subscriptions made from a member of that country where tblOrders.orderTypeID = 3 and tblSubscriptionPacks.TypeID = 2 in the next column


My problem was that I was doing joins, and I was somehow ending up with orders where the OrderTypeID was NOT equal to 3, even though I declared it specifically in the WHERE clause.

Can someone help me with this query?

SQL Server 2012 :: Adding Count To Query Without Duplicating Original Select Query

Aug 5, 2014

I have the following code.

SELECT _bvSerialMasterFull.SerialNumber, _bvSerialMasterFull.SNStockLink, _bvSerialMasterFull.SNDateLMove, _bvSerialMasterFull.CurrentLoc,
_bvSerialMasterFull.CurrentAccLink, _bvSerialMasterFull.StockCode, _bvSerialMasterFull.CurrentAccount, _bvSerialMasterFull.CurrentLocationDesc,
_bvSerialNumbersFull.SNTxDate, _bvSerialNumbersFull.SNTxReference, _bvSerialNumbersFull.SNTrCodeID, _bvSerialNumbersFull.SNTransType,
_bvSerialNumbersFull.SNWarehouseID, _bvSerialNumbersFull.TransAccount, _bvSerialNumbersFull.TransTypeDesc,

[code]...

However, as you can see, the original select query is run twice and joined together.What I was hoping for is this to be done in the original query without the need to duplicate the original query.

Very Slow Query (select Count(*) From Table)

Feb 15, 2006

Dear MS SQL Experts,I have to get the number of datasets within several tables in my MSSQL2000 SP4 database.Beyond these tables is one table with about 13 million entries.If I perform a "select count(*) from table" it takes about 1-2 min toperform that task.Since I know other databases like MySQL which take less than 1 sec forthe same taskI'm wondering whether I have a bug in my software or whether there areother mechanisms to get the number of datasets for tables or the numberof datasets within the whole database.Can you give me some hints ?Best regards,Daniel Wetzler

Programmatically Accessing An SQLDataSource With A SELECT COUNT(*) Query.

Jun 20, 2007

I've found example code of accessing an SQLDataSource and even have it working in my own code - an example would be  Dim datastuff As DataView = CType(srcSoftwareSelected.Select(DataSourceSelectArguments.Empty), DataView)  Dim row As DataRow = datastuff.Table.Rows(0)   Dim installtype As Integer = row("InstallMethod")  Dim install As String = row("Install").ToString  Dim notes As String = row("Notes").ToString The above only works on a single row, of course. If I needed more, I know I can loop it.The query in srcSoftwareSelected is something like "SELECT InstallMethod, Install, Notes FROM Software"My problem lies in trying to access the data in a simliar way when I'm using a SELECT COUNT query. Dim datastuff As DataView = CType(srcSoftwareUsage.Select(DataSourceSelectArguments.Empty), DataView) Dim row As DataRow = datastuff.Table.Rows(0) Dim count As Integer = row("rowcnt") The query here is "SELECT COUNT(*) as rowcnt FROM Software"The variable count is 1 every time I query this, no matter what the actual count is. I know I've got to be accessing the incorrect data member in the 2nd query because a gridview tied to srcSoftwareUsage (the SQLDataSource) always displays the correct value. Where am I going wrong here?

Nested SELECT Query That Also Returns COUNT From Related Table

Mar 4, 2005

OK heres the situation, I have a Categories table and a Products table, each Category can have one or many Products, but a product can only belong to one Category hence one-to-many relationship.

Now I want to do a SELECT query that outputs all of the Categories onto an ASP page, but also displays how many Products are in each category eg.

CatID | Name | Description | No. Products

0001 | Cars | Blah blah blah | 5

etc etc

At the moment I'm doing nesting in my application logic so that for each category that is displayed, another query is run that returns the number of products for that particular category. It works ok!

However, is there a way to write a SQL Statement that returns all the Categories AND number products from just the one SELECT statement, rather than with the method I'm using outlined above? The reason I'm asking is that I want to be able to order by the number of products for each category and my method doesn't allow me to do this.

Many thanks!

From Project
WHERE (SDCompleted > @SDCompleted) AND (SDCompleted < @SDCompleted2) AND (BusinessSector = 34) AND (req_type = 'DBB request ')

Select Statement With Count Within Another Select

Aug 23, 2013

I am using three tables in this query, one is events_detail, one is events_summary, the third if gifts. The original select statement counted the number of ids (event_details.id_number) that appear per event_name (event_summary.event_name).

Now, I would like to add in another column that counts the number of IDs that gave a gift who attended an event that were also listed in the event_ details table. So far I have come up with the following. My main issue is linking the subquery properly back to the main query. how to count in the sub-query and have the result placed within the groups results in the main query.

SELECT es.event_name, es.event_id, COUNT(ed.id_number) Number_Attendees,
(
SELECT COUNT(gifts.donor_id) AS Count2
FROM gifts
WHERE gifts.donor_id = ed.id_number
) subquery2

Obtain Unit Percent With Unit Count Divided By Total Count In Query

Aug 21, 2007

The following query returns a value of 0 for the unit percent when I do a count/subquery count. Is there a way to get the percent count using a subquery? Another section of the query using the sum() works.

Here is a test code snippet:


--Test Count/Count subquery

declare @Date datetime

set @date = '8/15/2007'


select
-- count returns unit data
Count(substring(m.PTNumber,3,3)) as PTCnt,
-- count returns total for all units

(select Count(substring(m1.PTNumber,3,3))

from tblVGD1_Master m1

left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID

Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9

and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0

and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)

and v1.[Date] between DateAdd(dd,-90,@Date) and @Date) as TotalCnt,
-- attempting to calculate the percent by PTCnt/TotalCnt returns 0
(Count(substring(m.PTNumber,3,3)) /

(select Count(substring(m1.PTNumber,3,3))

from tblVGD1_Master m1

left join tblVGD1_ClassIII v1 on m1.SlotNum_ID = v1.SlotNum_ID

Where left(m1.PTNumber,2) = 'PT' and m1.Denom_ID <> 9

and v1.Act = 1 and m1.Active = 1 and v1.MnyPlyd <> 0

and not (v1.MnyPlyd = v1.MnyWon and v1.ActWin = 0)

and v1.[Date] between DateAdd(dd,-90,@Date) and @Date)) as AUPct
-- main select

from tblVGD1_Master m

left join tblVGD1_ClassIII v on m.SlotNum_ID = v.SlotNum_ID

Where left(m.PTNumber,2) = 'PT' and m.Denom_ID <> 9

and v.Act = 1 and m.Active = 1 and v.MnyPlyd <> 0

and not (v.MnyPlyd = v.MnyWon and v.ActWin = 0)

and v.[Date] between DateAdd(dd,-90,@Date) and @Date

group by substring(m.PTNumber, 3,3)

order by AUPct Desc

Select Count Issue

Oct 18, 2007

Hello,We have a database filled with local restaurants for a directory. What I'm trying to do is display a list of all the cuisines and the number of restaurants who serve that type of cuisine in parentheses. It should look like the example below:American (12)Chinese (3)Italian (5)...Here are the tables with only the relevant columns: restaurants---------------...cuisine_id... cuisines-----------cuisine_idcuisine_name... So basically I want to pull all the names from the cuisines table and then the restaurant count from the restaurants table. The only way I can think of doing that is to grab the cuisine_ids, put them in an array and then use that in a loop to get the count from the restaurants table. That's not very elegant. Is there a better way?Thank you

Help With COUNT In SELECT Statement

Jul 20, 2005

Could someone assist with getting the count function working correctlyin this example please. I know the count function will return all rowsthat do not have null values, but in this case I want to count all therows except those with a zero sale price, (which are unsold).The table shows works offered for sale by an artist, with a positivefigure under SalePrice indicating a sale, and I want to count thenumber sold by each auction house, and sum the sale price by auctionhouse. The table is as follows:NameSalePriceAuctionDowling12000ChristiesDowling 0ChristiesDowling10000ChristiesDowling 0ChristiesDowling 0ChristiesDowling 6000SothebysDowling 0SothebysDowling 0SothebysDowling 8000SothebysDowling 0SothebysDowling 0SothebysDowling 0SothebysWhen I run this query:SELECT MyTable.Name, Count(MyTable.Name) AS [Number],Sum(MyTable.SalePrice) AS TotalSales, MyTable.AuctionFROM MyTableGROUP BY MyTable.Name, MyTable.AuctionHAVING (((MyTable.Name)="Dowling") AND ((Sum(MyTable.SalePrice))>0));The results are:NameNumberTotalSalesAuctionDowling 5 22000 ChristiesDowling 7 14000 SothebysThe TotalSales is correct, but the Number (Count) is incorrect, as therows with zero were also included. The results should be:NameNumberTotalSalesAuctionDowling 2 22000 ChristiesDowling 2 14000 SothebysHow do I prevent the unsolds (zeros) being counted?Thanks in advance,John Furphy

Count(*) And Select In The Same WITH Statement

Apr 22, 2008

Hi,

I have a query:

-- main select
WITH Orders AS
(
SELECT
ROW_Number() OVER(MyDate ASC) RowNo,
** rest o the query ***
)
SELECT *
FROM Orders
WHERE RowNo BETWEEN 100 AND 200
ORDER BY RowNo

--count of records
DECLARE @COUNT INT
SELECT @COUNT = COUNT(*)
FROM ** the same query as above ***
RETURN @COUNT


In this case it can happen that when counting records there will be different number of records that it was at time of paging. Also server has to execute this query twice and the query is quite complicated means that takes time.

Is there any better way to get number of rows in the same part of query with paging ?


Thanks for help

I'm doing something like SELECT * FROM LOGS. The primary key in this table is LogID.
I have another table that contains error messages. Each LogID could have multiple error messages associated with it. To get the error messages.
When I perform my first select query listed above, I would like one of the columns to be populated with ALL the error messages for that particular LogID (SELECT * FROM ERRORS WHERE LogID = MyLogID).
Any thoughts as to how I could accomplish such a daring feat?
