Returning A Count Of Items Including Zero
Jul 23, 2005
Hi,
I have 2 tables, Mail_subject and Mail_Usage.
Mail_Subject contains the subject, body and some other bits of info.
CREATE TABLE [Waterford_MailSubject] (
[ID] [int] NOT NULL ,
[MailSubject] [nvarchar] (50) COLLATE
SQL_Latin1_General_CP1_CS_AS NULL ,
[MailCategory] [nvarchar] (50) COLLATE
SQL_Latin1_General_CP1_CS_AS NULL ,
[MailBody] [ntext] COLLATE SQL_Latin1_General_CP1_CS_AS NULL ,
[MailCreateDate] [smalldatetime] NOT NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO
Mail_Usage records the amount of times a certain mail was sent.
CREATE TABLE [Waterford_MailUsage] (
[ID] [int] NOT NULL ,
[RepScreenName] [nvarchar] (50) COLLATE
SQL_Latin1_General_CP1_CS_AS NULL ,
[MemberScreenName] [nvarchar] (50) COLLATE
SQL_Latin1_General_CP1_CS_AS NULL ,
[MailSubject] [nvarchar] (50) COLLATE
SQL_Latin1_General_CP1_CS_AS NULL ,
[TimeDate] [smalldatetime] NULL ,
) ON [PRIMARY]
GO
They are joined by Subject (not my idea, its a DB ive inherited).
What i need is to get the Mail Subject and the number of times that
Mail was sent. Ive Joined them using an INNER JOIN which gave me a
count of the number of times each one occoured except for Mails that
have not been used. I need to get zero as the count of Mails not
sent. Ive tried a LEFT OUTER JOIN but it didnt work either.
Can someone point out what i need to do ?

Hi
I know this is going to sound embarassingly obvious, but i cannot find a quick solution.
I have some data, I display that data in a table. Simple so far.
I have a table footer, which I want to display the total number of rows returned.
For example
"Total Rows Returned ="
Now I know how to get the total rows returned:
CountRows("Dataset1")
However when I try to put the two together like this:
= "Total Rows Returned =" + CountRows("Dataset1")
I just get the whole thing outputted, and no total for totalrows...
Anyone know what I am doing wrong?

Hi All,
I have a question regarding recorcounts. I have a set of records that i got after writing the sql query. The record layout is something like:
ID Amountdue
1 5
2 10
3 40
4 0
5 -6
6 230
7 -5
8 100
9 -1
10 0
I want to get the count of each amount due more than 0, less than 0 and equal to 0 all in the same query. So the result should look something like
Order PassGT0 PassLT0 PassEQ0
1 5 NULL NULL
2 NULL 3 NULL
3 NULL NULL 2
i can do 3 separate select count(*) if these were stored in a table but the result set was created using joins in the Query Analyser. I can also achieve the above result using unions with 3 separate queries with different conditions but this way i have to join the tables 3 times in each query and this is slowing down the query.
Please let me know if there is some other way i can achieve this.
Thanks

I have the following table
Region Table
ID
ParentID
RegionName
RestaurantTable
ID
RestaurantName
RegionID
What i tried to do is count the number of restaurants by specific regionname. My current query is
Select RegionID, RegionName, count(*) as RestaurantNo
From Region Inner Join Restaurant
On Region.ID = Restaurant.RegionID
However I only get the results below
RegionID RegionName RestaurantNO
1 A1 0
2 A1.1 2
3 A1.2 1
4 A1.3 0
Where A1.1 , A1.2, and A1.3 are children of A1 in Region table
The result is not correct due to A1 should have 3 in RestaurantNo due to it contains A1.1 , A1.2 and A1.3
Could anyone help me to solve this problem.
Thank you

We sell & ship packages that contain multiple items within them. The actual package (we call it the "parent item") is in the same table as the items within it ("child items"). If the record is a child item within a package, its "ParentId" field will contain the ItemId of the package.
So some sample records of a complete package would look like this:
ItemId | ParentId | Name | QtyAvailable
----------------------------------------
1 | NULL | Package A | 10
2 | 1 | Item 1 | 2
3 | 1 | Item 2 | 3
ItemId's 2 & 3 are items contained within the ItemId 1 package.
Now however, the client wants us to build a report showing all packages (all items where ParentId is NULL) however, they want to see the QtyAvailable of not only the package but the items as well (a total of 15 when using the example above), all grouped into a single line. So a sample report line would look like this:
Name | Available Qty
--------------------------
Package A | 15
Package B | 100
How can I do a SELECT statement that SUMS the "QtyAvailable" of both the parent & child items and displays them along with the package name?

I want to get a count of how many PosAnswer are associated with the QuesToAsk 'List your top 5 favorite places'
This is the syntax I am using to achieve this, and it works, but wasn't sure if there was a better way (changing the data structure is unfortunately not an option in this situation). Here is my table structure
Code:
Create Table Test
(
QuesToAsk varchar(1000),
PosAnswer varchar(1000)

And this is the syntax I use to get the count I am after
Code:
DECLARE @VariableName varchar(25)

DECLARE @FieldCount int

Hi
I have written a stored procedure that accepts an argument which is the name of the table and the procedure returns me the number of rows in that table. It shows me the correct result but doesnt allow me to store the result in a variable. Here is the code
create procedure getRowCount
@v_table_name NVARCHAR(MAX)
as
DECLARE
@v_exec_query NVARCHAR(MAX),
@v_count BIGINT
begin
set @v_exec_query =(select 'select count(*) from ' + @v_table_name );
exec (@v_exec_query)
end
go
The above procedure is working fine. But i want to store the result in the @v_count variable. How can i do that?
Thanks and regards

I am doing a distinct count on a related table's column, but get an out of memory error if I run it for the entire table (works great for just a few rows when filtered down).The error I get is: "We couldn't get data from the external source.The operation has been cancelled because there is not enough memory available for the application. If using 32-bit version of the product consider upgrading.
I know I can add a related column and that works fine...but that seems to me like I've defeated the purpose, I have a good and proper lookup table, and should be able to run my query against its relationship.Here is the query and details below *Note I supplied a scaled down sample, on my actual model I receive these errors, not in the sample as it has only a few rows
List Workers Distinct Project Customers:=CALCULATE(DISTINCTCOUNT(Projects[CustomerID]),'WorkersToProjects')
Other measure which returns no errors, but included for completeness:
List Workers Projects:=CALCULATE(DISTINCTCOUNT([ProjectID]),ISBLANK(WorkersToProjects[ProjectID])=FALSE())
My goal here is to allow the user to view the workers assigned to a project, but also get counts of the workers assigned to the CUSTOMER of a project. For example, suppose we lose a customer, we want to see how many workers would be impacted by that, so a count of projects per worker is not useful there, we need to see a count of workers per project's customer (owner of project whom project work is being done for)The question being: How can I accomplish this:
1. WITHOUT adding a calculated column to WorkersToProjects (of Projects.CustomerID)
2. WITH better performance?
There must be a better way to write this DAX to still get the correct answer?*Pic of pivot table, again, the numbers are accurate but the formula used to List Workers Distinct Project Customers measure does NOT scale :( 3 count for red , the number of Projects John has and 2 count for blue, the unique customers/owners of those projects "Veridian Dynamics" and "Massive Dynamic".

I am struggling to come up with a set-based solution for this problem (i.e. that doesn't involve loops/cursors) ..A table contains items (identified by an ItemCode) and the set they belong to (identified by a SetId). Here is some sample data:
SetIdItemCode
1A
1B
24
28
26
310
312
410
[code]....
You can see that there are some sets that have the same members:
- 1 and 10
- 2 and 11
- 7, 8 & 9
What I want to do is identify the sets that have the same members, by giving them the same ID in another column called UniqueSetId.

I'm having an issue creating a report that can group & sum similar items together (I know in some ways, the requirement doesn't make sense, but it's what the client wants).
I have a table of items (i.e. products). Â In some cases, items can be components of another item (called "Kits"). Â In this scenario, we consider the kit itself, the "parent item" and the components within the kit are called "child items". Â In our Items table, we have a field called "Parent_Item_Id". Â Records for Child Items contain the Item Id of the parent. Â So a sample of my database would be the following:
ItemId | Parent_Item_Id | Name | QuantityAvailable
----------------------------------------
1 | NULL | Kit A | 10
2 | 1 | Item 1 | 2
3 | 1 | Item 2 | 3
4 | NULL | Kit B | 4
5 | 4 | Item 3 | 21
6 | NULL | Item 4 | 100
Item's 2 & 3 are child items of "Kit A", Item 5 is a child item of "Kit B" and Item 6 is just a stand alone item.
So, in my report, the client wants to see the SUM of both the kit & its components in a single line, grouped by the parent item. Â So an example of the report would be the following:
Name | Available Qty
--------------------------
Kit A | 15
Kit B | 25
Item 4 | 100
How I can setup my report to group properly?

I am opening a simple command against a view which joins 2 tables, so that I can return a column which is defined as a tinyint in one of the tables. The SELECT looks like this:
SELECT TreatmentStatus FROM vwReferralWithAdmissionDischarge WHERE ClientNumber = 138238 AND CaseNumber = 1 AND ProviderNumber = 89
The TreatmentStatus column is a tinyint. When I execute that above SQL SELECT statement in SQL Server Management Studio (I am using SQL Server 2005) I get a value of 2. But when I execute the same SQL SELECT statement as a part of a SqlDataReader and SqlCommand, I get a return data type of integer and a value of 1.
Why?

If it's a 0 (not a null, a 0) it doesn't get averaged in. For instance, values 0,1,2 should produce an average of 1.(0+1+2)/3 = 1. But sql is returning a value as if my 0's were nulls and not factored in: (1+2)/2 = 1.5Does anyone know why this is happening and how to fix it?

Hi,I'm trying to include a button control inside an iff where I am showing the results of a datalist. My aim is for each user listed, to show whether or not he is already a friend of the logged in user. To do this, I want to create an iff where if the user is already a friend, I will show the text "already a friend". If the user is not yet a friend, there will be a button saying "add as friend" which when clicked will execute an insert query to the database to add that user as a friend. I tried the code below, but it doesn't seem to recognize the button inside the iff. I really need a button to work if the result of the iff condition is DBNull.Value... Can anyone please help? <%#IIf(Container.DataItem("userNameIfFriend") Is DBNull.Value, "<asp:LinkButton id='addbuddy' runat='server' > Add as buddy</asp:LinkButton>", "Already buddy")%> I also tried the code below instead, but it doesn't work either, and I do not know what to include instead of true and false, since the button would only be enabled if the case was true. <asp:LinkButton id='addbuddy' runat='server' Enabled="<%#IIf(DataBinder.Eval(Container.DataItem, “userNameIfFriend�) is DBNull.Value, “True�, “False�)%>">Add as friend</asp:LinkButton> Thanks a lot.

I have a three server peer-to-peer replication setup that includes articles for tables and views. As I understand the BOL, scheme changes -- which I take to mean changes, amont other things, changes in the design of a table or view -- should automatically replicate to the other servers in the topology. Here are my quesitons:
When including a view as part of the publication, what is it, exactly, that is getting replicated? If all the tables supporting a given view are being replicated, and the view exists on all three boxes, whatelse, besides the view schema (and changes thereto) is being replicated?
Secondly, if in fact schema changes are replicated, why can't I modify a view that is part of a publication? When I try to make a change to such a view, I get a server timeout message, every single time. When I remove the view from the publication, I can make the modification with no trouble. What does replicating schema changes mean if I can't make changes to the schema?
Thanks for any enlightenment on this.

Hi All,
Here's my situation: I need to move several application db's to a new server. The current server is SQL 7.0 SP2, the new server will be SQL 7.0 SP3.
In order to avoid having the problems of mismatched logins and db user definitions, I'd like to restore the current master over the master that's created at install on the new server.
I was doing some testing of this by trying to restore the 7.0 SP2 master onto a SQL 7.0 DE edition and had some problems. (Obviously, this is not the exact scenario that I need to take place -- I want to restore standard edition to standard edition.)
Is restoring the master db from different service packs under 7.0 going to pose a problem? Is restoring the master db the best way to get around the logins issue when moving db's?
Thanks in advance for all replies.

Hi All
I have a table of students, and a table of lecturers, and I wish to use one select statement to return a list of users.
What I really need to do is something like this:
SELECT Students.UserID AS UserID, Lecturers.UserID AS UserID, Students.FullName AS FullName, Lecturers.FullName AS FullName FROM Students, Lecturers
which would (in my dream world!) produce something like:
UserID FullName
s0002131 Darren Student
s0054242 Richard Student
e13412 Michael Lecturer
x92342 Linda Lecturer
Does anyone know how I should do this? Should I be doing it in an stored proceedure and returning the record set from that? Currently I'm only using ASP and one line SQL statements, and would like to continue doing so.
