Hi All,
Can we use the while loop inside a select statement? Meaning, something like this:
Code Block
SELECT DATE,
WHILE (SELECT TOP 1 DATEPART(HH,DATE) FROM SC_DATEDIMENSION_TABLE) <= 23
(SELECT DATEADD(HH,6,SC_DATEDIMENSION_TABLE.DATE) )
FROM SC_DATEDIMENSION_TABLE
What I want to do here is I have a table which has all the dates but with time only representing 00 hrs. I want to display this column and along side, I want to have another column, which displays the date split at 6 hours. So, one left column, there will 4 columns on the right.
Hope the question is clear.
Thanks a lot.

Hi!I have a scalar function that returns integer:xview (int)Now, I'm trying to build a procedure that has the following selectinside:select atr1, xview(atr2)from tablenameBut, I get the 'Invalid name' error when I try to execute thatprocedure.If I got it right, I must use user.fn_name() syntax, but I cannot usedbo.xview() inside my procedure since it means xview will always beexecuted as dbo, which is unaccaptable.I'm a bit confused, so any hint is very welcomed.Thanks!Mario.
View 4 Replies View RelatedHi, can you add a counter inside a select statement to get a unique id line of the rows?
In my forum i have a page that displays a users past posts in the forum, these are first sorted according to their topicID and then they are sorted after creation date. What i want is in the select statement is to create a counter to get a new numeric order.
This is the normal way:
SELECT id, post, comment, created FROM forum_posts WHERE (topicID = @topicID) ... some more where/order by statements
This is what i want:
DECLARE @tempCounter bigintSET @tempCounter = 0SELECT @tempCounter, id, post, comment, created FROM forum_posts WHERE (topicID = @topicID)... some more where/order by statements and at the end.. (SELECT @tempCounter = @tempCounter + 1)
Anyone know if this can be done?
I have a need to execute a cursor inside a select statment, but I'm having problems figuring this out. The reason this need to be inside a select statement is that I am inserting the cursor logic into a query expression in PeopleSoft Query.
So! Here's the statement that works:
======================
DECLARE @fixeddate datetime
DECLARE @CVG_ELECT char(1)
DECLARE @Effdt datetime
DECLARE EFFDTS CURSOR FOR
SELECT Z.EFFDT, COVERAGE_ELECT
FROM PS_LIFE_ADD_BEN Z
WHERE Z.EMPLID = '1000'
AND Z.EFFDT <=
GETDATE()
AND Z.PLAN_TYPE = '20'
ORDER BY Z.EFFDT DESC
OPEN EFFDTS
FETCH NEXT FROM EFFDTS INTO @Effdt, @CVG_ELECT
WHILE @@FETCH_STATUS = 0
BEGIN
if @CVG_ELECT <> 'E'
break
ELSE
SET @fixeddate = @Effdt
FETCH NEXT FROM EFFDTS INTO @Effdt, @CVG_ELECT
END
CLOSE EFFDTS
DEALLOCATE EFFDTS
PRINT @fixeddate
======================
If I execute this in SQL Query Analyzer it gives me the data I am looking for. However, if I try to paste this into a select statement, it goes boom (actually, it says "Incorrect syntax near the keyword 'DECLARE'.", but you get the idea).
Is it possible to encapsulate this inside a select statement?

I m having problem with the "Select" function
the error I m getting is
Select statements included within a function cannot return data to a client (error 444)
Cann I use "select" statement in the function? If not what is the alternative?
I reduced the size of the sproc because it is a big one, I donn have any proble with syntax.
Thanks
Hi,
I've got a complex UDF I need to call twice in a select statement, as shown below:
SELECT
dbo.myFunction(colName),
dbo.myFunction(colName) * 2
FROM
tableName
The problem is, the result of "dbo.myFunction(colName)" is not being cached, so the function is executed again for "dbo.myFunction(colName) * 2". This is having a significant impact on performance (doubling the amount of time it takes for the query to execute).
Is there any way I can write the query so that dbo.myFunction is only executed once?
Thanks for your help,
Andrew
I'm trying to use the DateDiff function within my select statement, but I'd like to add the parameter of greater than 30 days. This will have the query only return records where my bill stop date is greater than 30 days from the completion date. I currently have the datediff function within my select statement as
DATEDIFF (d,A.StopBillDate, a.CompletionDate) as [DIFFERENCE]
I would prefer to keep the datediff function within the select statement so as to have difference in days appear as a column within my output.I have been unable to add the parameter of > 30 days to the query without getting an error.
Ok, for a bunch of cleanup that i am doing with one of my Portal Modules, i need to do some pretty wikid conversions from multi-view/stored procedure calls and put them in less spid calls.
currently, we have a web graph that is hitting the sql server some 60+ times with data queries, and lets just say, thats not good. so far i have every bit of data that i need in a pretty complex sql call, now there is only one thing left to do.
Problem:
i need to call an aggregate count on the results of another aggregate function (sum) with a group by.
*ex: select count(select sum(Sales) from ActSales Group by SalesDate) from ActSales
This is seriously hurting me, because from everything i have tried, i keep getting an error at the second select in that statement. is there anotherway without using views or stored procedures to do this? i want to imbed this into my mega sql statement so i am only hitting the server up with one spid.
thanks,

I am selecting the count of the students in a class by suing select COUNT(studentid) as StCount FROM dbo.student But I need to use a case statement on this like if count is less than 10 I need to return 'Small class' if the count is between 10 to 50 then I need to return 'Medium class' and if the count is more than 50 then 'Big class'.
Right now I am achieving this by the following case statement
SELECT 'ClassSize' = CASE WHEN Stcount<10 THEN 'Small Class'
WHEN Stcount>=10 and StCount<=50THEN 'Medium Class'
WHEN Stcount>50 THEN 'Big Class'
END
FROM(
select COUNT(studentid) as Stcount FROM dbo.student) Stdtbl
But can I do this with just one select statement?
I'm trying to execute a stored procedure within the case clause of select statement.
The stored procedure returns a table, and is pretty big and complex, and I don't particularly want to copy the whole thing over to work here. I'm looking for something more elegant.
@val1 and @val2 are passed in
CREATE TABLE #TEMP(
tempid INT IDENTITY (1,1) NOT NULL,
myint INT NOT NULL,
mybool BIT NOT NULL
)
INSERT INTO #TEMP (myint, mybool)
SELECT my_int_from_tbl,
CASE WHEN @val1 IN (SELECT val1 FROM (EXEC dbo.my_stored_procedure my_int_from_tbl, my_param)) THEN 1 ELSE 0
FROM dbo.tbl
WHERE tbl.val2 = @val2
SELECT COUNT(*) FROM #TEMP WHERE mybool = 1
If I have to, I can do a while loop and populate another temp table for every "my_int_from_tbl," but I don't really know the syntax for that.
Any suggestions?
The select statement:
SELECT DATEDIFF(n , LAG(CAST(Date AS DATETIME) + CAST(Time AS DATETIME), 1) OVER ( ORDER BY Date, Time ),
CAST(Date AS DATETIME) + CAST(Time AS DATETIME))
FROM [DataGapTest]
Gives the right output:
NULL
1
1
3548
0
However, when I put the statement in a function, I get only zeros as the output. It's as if the lag and current value are always the same (but they are not of course).
CREATE FUNCTION dbo.GetTimeInterval(@DATE date, @TIME time)
RETURNS INT
AS
BEGIN
DECLARE @timeInterval INT
SELECT @timeInterval = DATEDIFF(n , LAG(CAST(@Date AS DATETIME) + CAST(@Time AS DATETIME), 1) OVER ( ORDER BY Date, Time ),
CAST(@Date AS DATETIME) + CAST(@Time AS DATETIME))
FROM dbo.[DataGapTest]
RETURN @timeInterval
END
I tend to learn from example and am used to powershell. If for instance in powershell I wanted to get-something and store it in a variable I could, then use it again in the same code. In this example of a table order items where there are order_num, quantity and item_prices how could I declare ordertotal as a variable then instead of repeating it again at "having sum", instead use the variable in its place?
Any example of such a use of a variable that still lets me select the order_num, ordertotal and group them etc? I hope to simply replace in the "having section" the agg function with "ordertotal" which bombs out.
select order_num, sum(quantity*item_price) as ordertotal
from orderitems
group by order_num
having sum(quantity*item_price) >=50
order by ordertotal;
i have created the table empid,empname,dob,salary for the insert i need to create procedure of insert empid,empname,dob,salary i got the function for autogenerated number for empid

Is it possible to write dynamic sql on scalar function and assign the value to return value? I like some thing like below but it is not working...
Thanks
______________________________________________________________________
set @sql = 'select @CallLegKey= min(calllegkey) as CallLegKey
from rt_'+@platform+'_CallLegs
where datediff(day,convert(datetime, CallEndTime) ,'''+cast(@today as varchar(20))+''') = '+cast(@cutoff as varchar(5))
exec @sql
return @CallLegKey
Please find my second post in this thread.
Can anyone help me in sorting out the problem and let me know what might be the reason.
Thanks & Regards

Hello,
when trying to execute the following query with SQL CE 3.1 and OLEDB on WM2003:
SELECT C.Panel_Id, C.Panel_Tier, C.Panel_Type, C.Panel_No, C.Panel_Position
FROM tblMeasurements AS A, tblAssignment_Ant_Pan AS B, tblPanels AS C
WHERE (A.Measurement_No=?) AND (A.Antenna_No = B.Antenna_No) AND (B.Panel_Id = C.Panel_Id) AND C.Panel_Position in
(SELECT Panel_Position FROM tblMeasurement_Results
WHERE (Measurement_No=?) AND ABS(Measurement_Value) BETWEEN ? AND ?
GROUP BY Panel_Position)
i get this error returned:
0x80040E1DL -- DB_E_UNSUPPORTEDCONVERSION -- Requested conversion is not supported.
I don't know where inside the sql string a conversion is necessary/fails.
Surprisingsly when i modify the sql statement a little, it is executed WITHOUT ERRORS:
SELECT C.Panel_Id, C.Panel_Tier, C.Panel_Type, C.Panel_No, C.Panel_Position
FROM tblMeasurements AS A, tblAssignment_Ant_Pan AS B, tblPanels AS C
WHERE (A.Measurement_No=?) AND (A.Antenna_No = B.Antenna_No) AND (B.Panel_Id = C.Panel_Id) AND C.Panel_Position in
(SELECT Panel_Position FROM tblMeasurement_Results
WHERE (Measurement_No=?) AND Measurement_Value BETWEEN ? AND ?
GROUP BY Panel_Position)
The only difference between the 2 statements is the ABS() function inside the sub query.
More surprisingly, with the query analyser on the PDA i can execute both statements fine. I am absolutely confused now where i have to search for the mistake.
I would appreciate it very much if someone out there knows an answer or a hint and could tell me.
With kind regards,
Andre

I have created an assembly with permission set safe, and a function inside the assembly.
The function reads data from the same SQL Server as it is running inside. For connection I use the "Context connection = true", and the function has the SystemDataAccessKind attribute set to Read.
However when I execute my CLR function I get an error saying something like:
"The request for permission of type System.Data.SqlClient.SqlClientPermission...... failed"
I do, as the login user, have been granted the necessary rights, so I don't believe this is the answer to the error.
And my .dll is also signed.

Hello,
I have an if statement for one of my columns in my query.
I want to write the if statement as a part of my select statement.
How would I do that. Do to a couple of rules I am not allowed to write a stored procedure for this.
I could use the "decode function" but
I have something like this:
if column1 = '1' or column2 = '2' then select "Yes" etc..
I tried doing select decode (column1 or column2, , , ) but it doesn't work.
Any ideas?

View 6 Replies View RelatedI have several UDFs created. Inside one of the UDFs I need to execute a dynamic SQL statement and then take that result and do something else with it, before returning the final value.
I know you can not execute a stored proce from inside a function. I also know you can not use the EXEC statement.
I did read that you could use an external stored procedure and/or managed CLR procedures inside a function.
I have created a managed procedure CLR (C#) that simply executes a passed statemetn and returns the value to the calling routine. I have this all coded and is working fine.
However, I am struggling with knowing how to call this CLR procedure from inside my function, seeing how I can not use EXEC statement.
Any advice on how to do this?
Thanks,

I need a select that gets a value and than appends another value if the criteria is met otherwise nothing is appended.
The statement has a select with an imbedded select and when I execute it I get the error:
Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.
Thia is a crude sample of the statement
SELECT ID + ( select * from tableB where TableB = 0 ) as result1
FROM TableB
Why am I getting this error and how do I fix the statement?
thanks

View 5 Replies View RelatedCan someone please take a quick look at this and tell me what I'm doing wrong I'm sure it's something simple. I'm a little new to stored procedures but I've been using SQL and T-SQL for quite some time, I've just always used inline queries with my ASP. This procedure needs to be run monthly by me or another person I grant access to and will update sales information that our sales staff will be paid commission on. I need to supply the start date and and end date for the query and it will pull this information from our business system which is hosted remotely by a third party and pull it into our local SQL server where we can run commission reports against it. (I hope this is enough information you can understand where I'm trying to go with this). I know my problem right now lies in how I'm trying to call the variable inside of my T-SQL. Any help is appreciated. This is an old Unix system and it stores the date as YYYYMMDD as numeric values incase someone wonders why I have dimed my dates as numeric instead of as datetime =)

hi all,
i'm wondering if i can use one stored procedure in too cases, this is the senario:
i have stored procedure for admin and another one for user, they have the same select everything is the same except that in admin SP i have where @admin = admin and for user i have where @user = user
if there a way to use if and else to make this happen
this is what i did so far:
CREATE PROCEDURE [test] @admin INT, @user INT, @indexType INT as
if @indexType = 1
begin
SELECT * FROM table WHERE something IN (SELECT * FROM anothertable where admin = @admin)
end
else
begin
SELECT * FROM table WHERE user = @user
end
GO
any suggestion will be very helpful
thanks
