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.
IF (@CCTable = 'Claiminassoc') BEGIN IF ( @ClaimCenterField = 'ClaimID' AND @VALUE ='Claim') BEGIN UPDATE dbo.Table SET ColName = 'Y' WHERE ID = @ID AND CCTable = 'Claiminassoc' AND CCField = 'ClaimID' AND DWField = 'CatastropheDesignationFlag' END END
ELSE IF (@CCTable = 'EmploymentData') BEGIN IF (@VALUE ='TRUE') BEGIN UPDATE dbo.Table SET ColName = 'Y' WHERE ID = @ID AND CCTable = 'Claim' AND CCField = 'WagePaymentCont' END
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? SELECT TTarea,personel,Date FROM person_table WHERE TTarea = (SELECT TTarea FROM TTarea_table WHERE Center='CENTER_office') I have many TTarea and I want to send back from inner SELECT statement but give an error that inner select statement don't return many result.I want to return many result and I display many TTarea in the CENTER_office
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.
I want to write one query which will select multiple distinct records from one table For e:g Lets say in a table i have 3 fields name,tel_no,sex Now i want to list all the records which are distinct in each of these fields like distinct name,distinct address

i am new to SQL Server DB. i have a typical query problem. master table contains Data in following format id stype sid svalue 1 status 1 approved 2 status 2 pending 3 request 1 draft 4 request 2 waiting etc
in my query i need to substitute the svalue in place of sid e.g. select requestid ,bstatus, brequest from request ; should give --------------------------------- R1122 approved draft ------------------------------ instead of R1122 1 1 ***************** link field is column name (quite unusual ) like for status column , it is bstatus column name and it is stored in master table as status .
i need to do the following in 1 query only. kindly suggest some nested query to do the same kindly help Smita
I need to decrease the amount of time it takes to return a set of data of the following format:
State[Provided vai user intput]->All Counties in State->All Cities in County->All Zones in City[usually < 50 or 75 per city]
current behavior: 1. currently user selects state all counties are returned from db 2. foreach county cities are returned 3. foreach city streets are returned 4. objects hydrated with data & display drawn
As you can see this gets expensive. I know there has to be a better way to do this. Any suggestions? We use sql server/c#.net.
Hi there. I want to avoid a cursur using a quite basing nested while loop. The problem is, that the outer index-variable (i) won't increment at all while the inner loop works perfectly.
This one should be quite easy to solve I guess, I'd be very happy if someone could give me a hint what I should try, though because I don't know what to try. The manual didn't help me much either, using CONTINUE and BREAKs didn't solve this problem for me.

I've got a SP that selects the best price from a table that has all info collected into it. Selecting the price is easy, I use COALESCE.
But I want to have a column next to it that contains which price that was choosen. I used CASE and nested it... worked fine until I reached the 10th level, there is a limit there.
"Case expressions may only be nested to level 10."
I'm sure som people will puke when they see this code and I'm open to suggestions on how to do it in another way. I can always do it in two queries, but it should be possible to do it in one.

Important Tables: Product (table of products) --ProductID --ProductName
ProductCategories (Associates a Product with one or more categories) --ProductID --CategoryID
Category (table of categories that a product may fall under) --CategoryID --CategoryName
Information:
Basically I have a product that falls into two categories. Therefore there are two records in the ProcuctCategories Table. I am trying to create a query that will find all products that are in categories 1 & 2.
Attempted Solution: SELECT * FROM Product WHERE (ProductID IN (SELECT CategoryID FROM ProductCategories WHERE CategoryID =1)) AND (ProductID IN (SELECT CategoryID FROM ProductCategories WHERE CategoryID =2))
This returned zero records though it should have returned the product that is in categories 1&2.
I am writing a program using VC++ 6.0 and SQL 2000 and I am trying to use nested transactions. I have 1 outer transaction and the 2 inner transactions are in sepetrate function calls inside the outer transaction. I have something like this:
BEGIN TRANSACTION;
if (!functioncall1()) // commit if function suceeds, otherwise rollback { Rollback Transaction; return; }
if (!functioncall2()) // commit if function suceeds, otherwise rollback { Rollback Transaction; return; }
COMMIT TRANSACTION ;
Both functions contain a complete transaction inside the function call. If either function fails however, I want to do a rollback of the entire transaction. This is not happening though. If functioncall1 suceeds and the transaction in that function commits, then if I do a rollback during functioncall2, the transaction in functioncall1 is not rolled back. This seems to be directly opposite of the SQL help for transaction. Am I missing something obvious here?
