I am trying to do a nested count and cannot seem to get it to work. I do realize I cannot do this within the expression so I have been trying to use the code block (report > report properties > code tab) to do this and I have zero experience with VB.
This is for a PO delivery report. The first expression is just counting how many lines on an individual PO are late divided by total number of lines on the PO. In second expression I would like to count how many POs that have a late line on it.
Here is what I have so far.
Expression 1 with count function (this work properly):
=iif(Fields!DS_Desired_Recv_Date.Value is nothing,
((Count(IIF(Fields!LAST_RECEIVED_DATE.Value > Fields!DESIRED_RECV_DATE.Value,1,Nothing))/Count(Fields!LINE_NO.Value))),
((Count(IIF(Fields!ACTUAL_RECV_DATE.Value > Fields!DS_Desired_Recv_Date.Value,1,Nothing))/Count(Fields!LINE_NO.Value))))
Code block:
Private Shared count as Integer
count=0
Public Function IncrementCount() As String
count = count +1
IncrementCount = CStr(count)
End Function
HI All, I have what is most likely a simple MS SQL query problem (2005).I need to add two computed columns to a result set, both of those columns are required to provide the count of a query that contains a parmamter. (The id of a row in the result set) 3 Tables (Showing only the keys)t_Sessions-> SessionID (Unique) t_SessionActivity-> SessionID (*)-> ErrorID (Unique) t_SessionErrors-> ErrorID (1) I need to return something like (Be warned the following is garbage, hopefully you can decifer my ramblings and suggest how this can actualy be done) SELECT SessionID, (SELECT COUNT(1) AS "Activities" FROM t_SessionActivity WHERE t_SessionActivity.SessionID = t_Sessions.SessionID), (SELECT COUNT(1) AS "Errors" FROM dbo.t_Sessions INNER JOIN dbo.t_SessionActivity ON dbo.t_Sessions.SessionID = dbo.t_SessionActivity.SessionID INNER JOIN dbo.t_SessionErrors ON dbo.t_SessionActivity.ErrorID = dbo.t_SessionErrors.ErrorID WHERE t_SessionActivity.SessionID = t_Sessions.SessionID)FROM t_Sessions Any help greatfully received. Thanks
Hiya, I have a need for a complex SQL statement to provide reporting information, but the SQL is way over my head and although I have some of the elements, I can't seem to pull them together to create a working SQL statement. My database structure is as outlined below:
and then for A2, etc (although missing out A3 as it is a text item, but I can deal with that via ASP code beforehand). I would expect to have to hit the DB for each of the IRVitems (so once for getting the data for A1, againfor A2, etc).
I was provided a great bit of code to use SUBSTRING and GROUP BY to get this data (thanks zuomin), but I didn't consider the possible text values or numbers >9 when defining what I was trying to do (to be fair, they're new requirements):
SELECT SUBSTRING(IRVvalues, 1, 1) AS Value, COUNT(ID) AS Count FROM tblIRV GROUP BY SUBSTRING(IRVvalues, 1, 1) ORDER BY value
which returns like this:
Value Count 1 187 2 163 3 2
Can I do a similar query to get all the info I need in one go? I saw the articale on a user-defined 'split' function (http://code.msdn.microsoft.com/SQLExamples/Wiki/View.aspx?title=StringArrayInput&referringTitle=Home) that can be used to split up the IRVvalues string to access the position I need in the array, but I'm a little clueless on how to then embed that into a SQl statement. Can anyone point me in the right direction please?
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
I have added some SQL to an Access form which updates the dbo_BM_Map table when the user hits the Apply button. There is a temp table with various fields, two being "Chapter_No" and "Initial_Mapping_Complete" which the update is based on.
I want this update to only apply to chapters that only have one name in the "Initial_Mapping_Complete" column. If a chapter has more than one then the update should ignore it. The attached screengrab shows you. The update should ignore chapter 19 as there are two people (Jim and James) in the Initial_Mapping_Complete field. Here is my code.
pdate dbo_BM_Map inner Join Temp_Progression_Populate on dbo_BM_Map.Product_ID = Temp_Progression_Populate.Product_ID Set dbo_BM_Map.Initial_Mapping_Complete = Temp_Progression_Populate.Initial_Mapping_Complete Where dbo_BM_Map.Chapter_No = Temp_Progression_Populate.Chapter_No And Temp_Progression_Populate.Initial_Mapping_Complete in (Select count(Initial_Mapping_Complete), Chapter_No from Temp_Progression_Populate Group by Chapter_No Having Count(Initial_Mapping_Complete) = 1)
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.

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)) /

Can you give a whole SQL statement an alias so you can use it later?
Eg.
SELECT * FROM Employees WHERE age < 19 -- Could I call the above statement something like 'statement1' to use below as shown
SELECT * FROM Employees WHERE age < 25 AND NOT IN (statement1)
Soin effect I get a nested statement. The reason I am asking about aliases is because this would need to be repeated for, E.g. age < 30 Then age < 35 and so on and so forth.
So basically, I just want to alias a qhole SQL statement
Hi all,I have a query that looks like so:SELECT GLDCT AS [Doc Type], GLDOC AS DocNumber, GLALID ASPerson_NameFROM F0911WHERE (GLAID = '00181913')However by stipulating that GLAID = GLAID I cannot get the person_nameas not all the GLALID fields are filled in. from my reading of thehelpdesk I have a felling that a nested query might be the way to goor a self-join but beyond this I am lost!?Many thanks for any pointers in advance.Sam
I am trying to do some nested IF ELSE conditions. I get an error saying 'Error near work Begin'. Below is teh query and the variables comes in thru cursor.
Can somebody advise me on this and also let me know the best practices and alternative to this if any.

ELSE IF (@VALUE ='FALSE') BEGIN UPDATE dbo.Table SET ColName = 'N' WHERE ID = @ID AND CCTable = 'Claim' AND CCField = 'WagePaymentCont' END END
I have a challenge, which seems like it is probably trivial, but SQL chops are not up to the task, and I am hoping one of you hot-shot DBAs can throw me a bone!
I have a query that populates an OLAP Time dimension table (basically one row per day of the year over several years). What I want to do is expand that table to include each hour of each day over the time span.
The CTE I am using for the day population is:
Code Snippet WITH dates(date) -- A recursive CTE that produce all dates between 2006 and 2057-12-31 AS ( SELECT cast('2006' AS dateTime) date -- SQL Server supports the ISO 8601 format so this is an unambigious shortcut for 1999-01-01 UNION ALL -- http://msdn2.microsoft.com/en-us/library/ms190977.aspx SELECT (date + 1) AS date FROM dates WHERE date < cast('2058' AS dateTime) -1 )
What I wanted to do was something like:
Code Snippet WITH hours(hr) AS ( SELECT (DATEPART(hh,date) hr UNION ALL SELECT (hr + 1) AS hr FROM hours WHERE hr < 24 )
inserted just after
Code Snippet FROM dates
in the initial CTE. But from what I have read, it seems as though nested CTEs are not allowed.
Can someone pls advise the maximum number of nested IIF statements allowed in a VS 2005 report builder layout textbox expression? I seem to be hitting a wall at about 10, but cannot find verification. In case the limitation is by characters, the full expression would run about 3,500. Any other limitations which may have a bearing?
Hi all! I have a problem with my stored procedure, What I'm trying to do here is whenever a user tries to register, the stored procedure will check if the username already exists, and if not it'll now check if the email has already been entered into the database then if not the stored procedure will go ahead and insert the values into the database. *If the username already exists it'll return -1, and if the email already exists then return -2.
SELECT Username FROM UserAccount WHERE Username = @UsernameIF @@ROWCOUNT = 0 SELECT Email FROM UserAccount WHERE Email = @Email IF @@ROWCOUNT = 0 BEGIN
INSERT INTO UserAccount (Username, Password, Email, FirstName, LastName, Gender, BirthDate, Country, State, Zip, AdditionalInfo) VALUES (@Username, @Password, @Email, @FirstName, @LastName, @Gender, @BirthDate, @Country, @State, @Zip, @AdditionalInfo) END ELSE BEGIN
Hi, I'm not sure if this is a good place to ask sql questions, so please bear with me here...I have a table like soid, parentidWhat I'm trying to do is to write a self join where given a random ID, it'll give me the whole tree of its decendents. (I don't need its parent)so say I have data liek soid parentid1 null2 13 2when I specificy 1, it'll give me 2 and 3, even though 3 is indirectly related to 1. when I say 2, it'll just give me 3. Thanks a lot. GREATLY appreicate it.
What's worng, please help?

Im inserting some data into a table and grabbing the new UserID with this statement
SELECT @UserID = @@IDENTITY
I would like to use the @UserID to Execute another SP within the same proc.. ..something like this
Exec AnotherSP(@UserId)
But this doesnt seem to be working....Its seems to me that this is a much better approach performance wise rather than returning the UserID to the Business Logic Layer and calling another SP....Im I correct in that assumption....any assistance would be greatly appreciated.
I think I am getting an endless loop here... anyone know how to fix it?

Hi, Although I am quite familiar with MS Access-grade SQL, I am struggling a bit with proper grown up SQL Server. My usual approach to counting things in Access is to first create a query with the conditions on the data, then use this as the basis of a second query that does the actual counting of the presorted data. I believe the way to do this in SQL server is to use a nested query. I want to generate the top 10 highest counts for each pesticide detected (detection is level>0) for a client between two dates. Currently I am using <code> SELECT top 10 Count(Pesticide) AS CountOfPesticide, Pesticide FROM (SELECT tblData.Pesticide, tblData.Level, tblData.Clast, tblData.Client FROM tblData WHERE (((tblData.Day>@sdate) AND (tblData.Day<@edate))) and (tbldata.level>0) and (tbldata.clast=@clast) and (tbldata.client=@client)) as monkeyboy GROUP BY Pesticide ORDER BY Count(Pesticide) ASC" </code> The results that the above SQL turns out though are not reliable. For example, if I set the dates to now and 14 days ago, it produces higher counts for some pesticides then if I set the dates to now and 30 days ago. Any pointers or general advice about nested sql is gratefully accepted! thanks Mike
Hi,Please can somone help me with a nested SQL query. I have two tables please see belowTable 1CallIDEmployeeIDCallSummaryCallStatusTable 2CallHistoryIDCallIDDataAddedCallActionI would like to return the CallID, EmployeeID, CallSummary and CallStatus from Table 1, and also display the last CallAction from Table 2.This is a helpdesk database so a Call will have many CallActions i.e. Open, Held, Assigned Internal. How do I return the last CallAction Added against the selected CallID, I know I use the DateAdded but not sure about nested statements.The results I would like to return to the user would look like this:-Call ID: 1EmployeeID: 1Call Sumary: SQL ProblemCall Status: OpenCall Action (Last Action): Assigned Internal.
-- declare cursor to return the from lat and lon for all segments that do not have address point 109. DECLARE c1 CURSOR FOR (SELECT From_Latitude, From_Longitude, id AS segment_id FROM Segments WHERE SegmentType != 109) OPEN c1 FETCH NEXT FROM c1 INTO @fLat, @fLon, @segId WHILE @@FETCH_STATUS = 0 BEGIN -- insert into table the segId, from lat, from lon and returned segment id from function. INSERT INTO test VALUES (@segId,@fLat,@fLon,dbo.points_test(@fLat,@fLon))
FETCH NEXT FROM c1 INTO @fLat, @fLon, @segId END
CLOSE c1 DEALLOCATE c1
As you can see here I am using a Cursor, which in turn calls a function with each row that is processed in the recordset. The function that is called is as follows...
ALTER FUNCTION points_test(@x INTEGER, @y INTEGER) RETURNS INTEGER AS BEGIN -- function to find the closed segment point with address point 109 to the segment specified in procedure. DECLARE @tempDistance FLOAT(4) SET @tempDistance = 1000000 DECLARE @id, @seg, lat, lon INTEGER DECLARE @distance, @xd, @yd FLOAT DECLARE c1 CURSOR FOR (SELECT from_latitude, from_longitude, id FROM segments WHERE segmenttype = 109) OPEN c1 FETCH NEXT FROM c1 INTO @lat, @lon, @id WHILE @@FETCH_STATUS = 0 BEGIN -- calucations to get distance. SET @xd = (@lat-@x) SET @yd = (@lon-@y) SET @distance = SQRT((@xd*@xd) + (@yd*@yd))
-- test if you have shortest distance. IF (@distance < @tempDistance) BEGIN SET @tempDistance = @distance SET @seg = @id END FETCH NEXT FROM c1 INTO @lat,@lon, @id END CLOSE c1; DEALLOCATE c1; RETURN @seg END
(This function works out an equation to get the shortest distance from two parameters passed to the function calculated with data from each row returned within the cursor) As you can see here, this function contains ANOTHER cursor!! Ouch. The fact that their is an SQL query in a function is a killer, but having another embedded cursor there is also a killer - this has virtually killer the application.
So, how best is it for me to correct this. Should I turn the function into a stored procudure? But even if I do this, the nested cursor still remains. I was thinking maybe to have the SQRT equations within the SELECT expression and then wrapped in a MIN() to maybe get the lowest value.
I have a question why does not the following nested transaction work?
begin tran insert into t1 values('A') begin tran insert into t2 values('1') commit insert into t3 values('B') begin tran insert into t2 values('2') commit rollback
I have a situation where I have two cursors: outer_cursor and inner_cursor. The inner_cursor is supposed to execute based on a value passed on from outer_cursor. It is not running as desired. At runtime, it complians that the inner_cursor is not open.
