How Do I Use A Pre-defined Sql Query?
Jul 18, 2006
Hi there, hope you can help me. What should I do if I want to use a pre-defined string as sql query (SelectCommand)? So I want to use the sqlquery string in the SelectCommand option...
The reason is that this page is request like page.aspx?ID=1234, and I want to use the Request.QueryString option to define the sql query...
<HTML>
<head>
<sript runat"server">
Dim sqlquery As String = New String ("SELECT LastName FROM Employees")
</script>
<BODY>
<FORM runat=
"server">
<asp:SqlDataSource
id=
"SqlDataSource1"
runat=
"server"
DataSourceMode=
"DataReader"
ConnectionString=
"<%$ ConnectionStrings:MyNorthwind%>"
SelectCommand=
"SELECT LastName FROM Employees">
</asp:SqlDataSource>
</FORM>
</BODY>
</HTML>

I'm experiencing quite an interesting issue with our database. We're currently running SQL Server 2005 Standard (x64) (v9.00.3054.00) and I have a block of code that just insists on not working within a UDF. Everything I've read seems to point that I'm doing this corerctly but apparently I'm missing something.
Executing the query below:
DECLARE @sp DATETIME
DECLARE @ep DATETIME
DECLARE @trackType INT
SET @sp = '4/21/2008'
SET @ep = '4/28/2008'
SET @trackType = 1
SELECT
c.unqempid, isnull(count(c.contactid),0) AS contacts, isnull(bookings.count,0) AS bookings, isnull(showed.count,0) AS showed, isnull(ow.totalPurchased,0) AS purchases, isnull(ow.totalSold,0) AS volume
FROM
contacts c WITH (NOLOCK)
LEFT JOIN
(
SELECT
b.unqempid, ISNULL(count(bookingid),0) AS count
FROM
bookings b WITH (NOLOCK)
INNER JOIN
contacts c WITH (NOLOCK)
ON c.contactid = b.relcontactid
WHERE
c.contactdt BETWEEN @sp AND @ep
GROUP BY
b.unqempid
) AS bookings
ON bookings.unqempid = c.unqempid
LEFT JOIN
(
SELECT
b.unqempid, ISNULL(count(bookingid),0) AS count
FROM
bookings b WITH (NOLOCK)
INNER JOIN
contacts c WITH (NOLOCK)
ON c.contactid = b.relcontactid
WHERE
c.contactdt BETWEEN @sp AND @ep AND didshow > 0
GROUP BY
b.unqempid
) AS showed
ON showed.unqempid = c.unqempid
LEFT JOIN
(
SELECT
c.unqempid, count(leadid) TotalPurchased, sum(saleprice) AS TotalSold
FROM
ordermgmt.dbo.orders o WITH (NOLOCK)
INNER JOIN
ordermgmt.dbo.appointments a WITH (NOLOCK)
ON a.weborderid = o.orderid
INNER JOIN
contacts c WITH (NOLOCK)
ON c.personid = a.leadid
INNER JOIN
bookings b WITH (NOLOCK)
on b.relcontactid = c.contactid
WHERE
c.contactdt BETWEEN @sp AND @ep
GROUP BY
c.unqempid
) as ow
ON ow.unqempid = c.unqempid
WHERE
c.contactdt BETWEEN @sp AND @ep
GROUP BY
c.unqempid, bookings.count, showed.count, ow.totalPurchased, ow.totalSold
Yields no issues however if I put this into a UDF, it runs and never finishes executing. I'm not quite sure what my issue was so I'm hoping someone could point out where my goof is.
Here is the function:
CREATE FUNCTION [dbo].[fnEmployeeSchedulingResults]
(
@sp DATETIME,
@ep DATETIME
)
RETURNS TABLE
AS
RETURN
(
SELECT
c.unqempid, isnull(count(c.contactid),0) AS contacts, isnull(bookings.count,0) AS bookings, isnull(showed.count,0) AS showed, isnull(ow.totalPurchased,0) AS purchases, isnull(ow.totalSold,0) AS volume
FROM
contacts c WITH (NOLOCK)
LEFT JOIN
(
SELECT
b.unqempid, ISNULL(count(bookingid),0) AS count
FROM
bookings b WITH (NOLOCK)
INNER JOIN
contacts c WITH (NOLOCK)
ON c.contactid = b.relcontactid
WHERE
c.contactdt BETWEEN @sp AND @ep
GROUP BY
b.unqempid
) AS bookings
ON bookings.unqempid = c.unqempid
LEFT JOIN
(
SELECT
b.unqempid, ISNULL(count(bookingid),0) AS count
FROM
bookings b WITH (NOLOCK)
INNER JOIN

ON ow.unqempid = c.unqempid
WHERE
c.contactdt BETWEEN @sp AND @ep
GROUP BY
c.unqempid, bookings.count, showed.count, ow.totalPurchased, ow.totalSold
)
Any help would be greatly appreciated!

What is better for performance, using a user defined function or a sub query to perform an aggregate calculation in a select statement. for eg would it be best to call a user defined function which performs the below calculation of the sub query shown. I'm speaking purely from a performance point of view.
SELECT o.ordersid,
o.orders,
(SELECT SUM(i.total) FROM items AS i WHERE i.ordersid = o.ordersid) AS [total]
FROM order AS o

I have the following procedure, that calls a Padding function to pad characters to a field.
Here is what the procedure looks like
Code:
CREATE PROCEDURE [dbo].[Pad_Left]
@Table VARCHAR(255),
@Column VARCHAR(255),
@PadChar CHAR(1),
@PadToLen INT
AS
DECLARE @Query Varchar(5000)
SET @Query = 'UPDATE ' + @Table + '
SET ' + @Column + ' = dbo.Function_PadLeft(' + @Column + ', ''' + @PadChar + ''', ' + @PadToLen + ')'
EXECUTE(@Query)
GO
When I run this I get the error
Server: Msg 245, Level 16, State 1, Procedure Pad_Left, Line 13
Syntax error converting the varchar value 'UPDATE Lincoln
SET baths = dbo.Function_PadLeft(baths, '0', ' to a column of data type int.
But when I just run this query, it works
Code:
CREATE PROCEDURE [dbo].[Pad_Left]
@Table VARCHAR(255),
@Column VARCHAR(255),
@PadChar CHAR(1),
@PadToLen INT
AS
UPDATE Lincoln
SET Baths = dbo.Function_PadLeft(Baths, '0', 4)
GO
Why would one work but not the other? I don't understand, as they are the same thing, just one calls the function dynamically?
I must be missing something very obvious
Thanks for any help!

Hi,
I wonder if its possible to perform a ORDER BY clause in an SELECT DISTINCT sql query whereby the AS SINGLECOLUMN is used. At present I am recieving error: ORDER BY items must appear in the select list if SELECT DISTINCT is specified. My guess is that I cant perform the Order By clauses because it cant find the columns individually. It is essentail I get this to work somehow...
Can anyone help? Thanks in advance

2 examples:
1) Rows ordered using textual id rather than numeric id
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
order by
v.id
Result set is ordered as: 1, 11, 2
I expect: 1,2,11
if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
2) SQL server reject query below with next message
Server: Msg 169, Level 15, State 3, Line 16
A column has been specified more than once in the order by list. Columns in the order by list must be unique.
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
cross join (
select 1 id
union select 2 id
union select 11 id
) u
order by
v.id
,u.id
Again, if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
It reproducible on
Microsoft SQL Server 2000 - 8.00.2039 (Intel X86) May 3 2005 23:18:38 Copyright (c) 1988-2003 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
and
Microsoft SQL Server 2005 - 9.00.3042.00 (Intel X86) Feb 9 2007 22:47:07 Copyright (c) 1988-2005 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
In both cases database collation is SQL_Latin1_General_CP1251_CS_AS
If I check quieries above on database with SQL_Latin1_General_CP1_CI_AS collation then it works fine again.
Could someone clarify - is it bug or expected behaviour?

Hi, i'm a beginner in DTS / Activex , in SQL Server 2000.
I need to update 500.000 records of a TableB (containing 2.000.000 rows) with a TableA (containing 500.000 rows)
With Enterprise Manager I made a new DTS package (my first package!)
I define / drag 2 Connections as OLE (the first-right icon)
(but i don't define any Activities as dts. Then i define the following ActiveX (VBs) :
Function Main()
if DTSDestination("NDG") = (DTSSource("NDG")) THEN
DTSDestination("BANCA") = DTSSource("BANCA")
DTSDestination("NDG") = DTSSource("NDG")
'Pao: LA LOGICA DELLA TRASFORMAZIONE
if (DTSSource("PTF")) > 0 THEN
IF (DTSSource("SEGMENTO")) > 0 THEN
DTSDestination("CAMPO_N1") = DTSSource("SEGMENTO")
DTSDestination("PTF_CLIENTE_OLD") = DTSSource("PTF")
ELSE
DTSDestination("CAMPO_N1") = DTSDestination("SEGMENTO_CLIENTE")
DTSDestination("PTF_CLIENTE_OLD") = DTSSource("PTF")
END IF
ELSE
IF (DTSSource("SEGMENTO")) > 0 THEN
DTSDestination("CAMPO_N1") = DTSSource("SEGMENTO")
DTSDestination("PTF_CLIENTE_OLD") = 0
ELSE
DTSDestination("CAMPO_N1") = DTSSource("SEGMENTO")
DTSDestination("PTF_CLIENTE_OLD") = DTSSource("PTF")
END IF
END IF
END IF
Main = DTSTransformStat_OK
End Function
+++++++++++
but when I run it I obtain the following error message: DTSDestination not defined, idem for DTSSource.
Please help me, it's IMPORTANT !

I have a UDF that takes my input and returns the next valid business day date. My valid date excludes weekends and holidays.
It works perfect except for one issue. It doesn't check to see if today's date is a holiday.
I pass a query to sql server like so " select dbo.getstartdate('01/ 10/2007',2)"
It then moves ahead two business days and returns that date.
Here is the current code. Hopefully someone can tell me how to do the holiday check on the current date.
I really don't want to rewrite the whole script .
Code---------------------------------------------------------
SET QUOTED_IDENTIFIER OFF GOSET ANSI_NULLS OFF GO
--DROP FUNCTION GetStartDate
--declare function receiving two parameters ---the date we start counting and the number of business days
CREATE FUNCTION GetStartDate (@startdate datetime, @days int) RETURNS datetimeASBEGIN
--declare a counter to keep track of how many days are passingdeclare @counter int
/*Check your business rules. If 4 business days means you count starting tomorrow, set counter to 0. If you start counting today, set counter to 1*/set @counter = 1
--declare a variable to hold the ending datedeclare @enddate datetime
--set the end date to the start date. we'll be -- incrementing it for each passing business dayset @enddate = @startdate
/*Start your loop.While your counter (which was set to 1), is less than or equal to the number of business days increment your end date*/WHILE @counter <= @days
BEGIN
--for each day, we'll add one to the end dateset @enddate = DATEADD(dd, 1, @enddate)
--If the day is between 2 and 6 (meaning it's a week --day and the day is not in the holiday table, we'll --increment the counter IF (DATEPART(dw, @enddate) between 2 and 6) AND (@enddate not in ( select HolidayDate from tFederalHoliday where [HolidayYear] = datepart(yyyy,@enddate) ) ) BEGIN set @counter = @counter + 1 END

I've a view in which one of the fields were DATEDIFF(day,contract date,received) AS AgeOfAccount. I changed it to DATEDIFF(day, m.received, CASE WHEN m.clidlp > m.clidlc THEN m.clidlp ELSE m.clidlc END) * - 1 AS AgeOfAccount. When I execute the view I'm getting an error. But the results are getting displayed properly. That's what's puzzling me. Could someone tell me what the error is.
The following errors were encountered while parsing the contents of the sql pane.
Your entry cannot be converted to a valid date time value.

Hi,
I have a search returning many 'car' records (regno, mileage, color, etc)
In a seperate table I have two columns: accessory and regno. This can have many rows for each regnumber.
Within the storedprocedure that returns the 'car' records I need to also return the relevant accessories for that car as one column.
I have written a function as such (with some help!):
ALTER Function getAccs(@regNo varChar(20))
RETURNS varChar
AS
BEGIN
Declare @List varchar(1000)
SELECT @List = COALESCE(@List + ', ', '') + accessory
FROM frxrep2.dbo.usedaccessories WHERE regnumber = @regno
return @List
END
I was hoping that I could simply use this in the 'car' SELECT statement.
ie:
SELECT regNo, color, mileage, dob.getAccs(regno) as AccessoryList
FROM tableBla etc
I'm not even sure if the function works - How can I test in SQL analyzer?
any help much appreciated,
Pete

Hi everyone,
I am tring to pass acomma delimited string to a function and this function is parsing the string so that I can see individual values so for example I am passing 1,2,3,4,5 as a parameter to my function and I am parsing this string so that I can write something like this
Select * from tableA where userID in(1,2,3,4)
It is working fine. Only problem is if the user passes word 'all' instead of 1,2,3,4 then I have to doSelect * from tableA
My function looks like this. How can I modify this function if I pass 'all' as a paramater. Any help will be appreciated.CREATE FUNCTION [dbo].[ParseText2File] (@p_text varchar(4000), @p_Delimeter char(1))
RETURNS @results TABLE (id varchar(100))
AS
BEGIN
declare @i1 varchar(200)
declare @i2 varchar(200)
declare @tempResults Table (id varchar(100))
while len(@p_text) > 0 and charindex
(@p_Delimeter, @p_text) <> 0
begin
select @i1 = left(@p_text, charindex(@p_Delimeter, @p_text) - 1)
insert @tempResults select @i1
select @p_text = right(@p_text, len(@p_text) - charindex(@p_Delimeter,@p_text))
end
insert @tempResults select @p_text
insert @results
select *
from @tempResults
return

I cannot believe that is not possible in SQL 7.0, can somebody tell me what is the work around, I am running against time. I really appreciate any help on this one.

Dear friends,
I am a new user for SQL server. Coming from an oracle background, I find it very difficult to live without user defined functions. At the moment, I urgently need to have a function returning an custom-made ID string, so that it can be used in one of my stored procedures. I have heard the rumours that SQL server 7 does NOT support user defined functions, (which SQL 6.5 does). I would be really grateful if anyone can clarify this for me, and if possible, suggest a get-around approach.
Thanks in advance!

I am trying to compare the data from one table (shipments) with the data from a view. The point of the function is to match the correct territory with the account depending on the data. Basically, I this deals with accounts that are transfering from one territory to another. The transfers take effect on the first day of the month, retroactive, therefore we need to allocate the sales data to the correct territory in the shipments table. Here is my function. Can someone tell me how I can get this to work and insert a territory ID for the account that has transfered into the shipments table?
CREATE FUNCTION fnShipments ()
RETURNS @Shipments TABLE (AccountID CHAR(10), DateInvoice DateTime, DollarShipments Money, TerritoryID CHAR(10))
AS
BEGIN
INSERT @Shipments (AccountID, DateInvoice, DollarShipments, TerritoryID)
SELECT Shipments.AccountID, Shipments.DateInvoice, DollarShipments, ISNULL((SELECT TerritoryID FROM vwAccountTransfers
WHERE Shipments.AccountID = vwAccountTransfers.AccountID
AND vwAccountTransfers.EffectiveMonth =
(SELECT MIN(EffectiveMonth)
FROM vwAccountTransfers
WHERE Shipments.AccountID = vwAccountTransfers.AccountID
AND DatePart(m,Shipments.DateInvoice) < vwAccountTransfers.EffectiveMonth)),
(SELECT TerritoryID FROM vwAccountTransfers
WHERE Shipments.AccountID = vwAccountTransfers.AccountID
AND vwAccountTransfers.EffectiveMonth Is Null )
) AS Territory
FROM Shipments
ORDER BY Shipments.AccountID, Shipments.DateInvoice;

I need a UDF that will do the following:
User: Will be sending me a datetime e.g '9 Nov 2004 15:00:00'
I want the UDF to do the following for me
Return in hours the difference between what the user has send and now (lets say now = '10 Nov 2004 11:00:00')
So the UDF will return to me 20.
But I dont want 20, I want the UDF to avoid any all hours which are not work related (any time after 16h00
until 8h00 in the morning), so I want this UDF to return 4. That means from '9 Nov 2004 15:00:00' I have calculated
1hr until 16h00 and 3hrs from 8 until 11h00 on '10 Nov 2004 11:00:00'
AGAIN IT MUST NOT CALCULATE WEEKENDS. Lets say '12 Nov 2004 15:00:00' was Friday and now = '15 Nov 2004 11:00:00', I must still
get 4 as a return from UDF
I would also like now to be my getdate(), but it seems like you can't use it in UDF

Hi everyone
I am implementing an encrypted data system whereby captured data is encrypted using MS CAPICOM when written to DB and decrypted when displayed. It works well. However, each time you write the data back on update the encryption is different from the previous time.
I have a search screen that allows users to enter text data and submit it looking for matches. Of course, the user is entering unencrypted text and the DB data is encrypted.
This means that you can't encrypt the input data before you try to match because the encryption alogorithm used on the input data will not match that which was used to encrypt the DB data.
Are you with me so far?
So, you have to compare the uncencrypted input data with DECRYPTED DB data - in other words, decrypt the DB data on the fly within the where clause of your query.
I have accomplished this by writing a UDF that instantiates an instance of the CAPICOM encryption module and calling the UDF when applying the query
eg where udf(columnname1) = 'inputtext' or udf(columnname1) = 'inputtext'.
It works, I get the results that I want.
But, alas, the performance has taken a search severe hit.
Has anyone else ventured down this road?
Is there a better way of doing this?
Thanks

I've been doing some reading on UDT's and have a question...
It was suggested in one of the pieces I read that you could create a UDT for, in their example, cities. And every table that had a reference to city could share this datatype. Now, my initial thought was "wow, what a great idea! I wouldn't have to remember the exact datatype for my primary keys (was it a char(5) or char(6)?) and have a "central depository" for my key datatypes.
So the first question is; what are the disadvantages of such a design?
And the second is; How do you update a UDT? If business requirements change and udt_city needs to be changed from varchar(30) to varchar(60), for example, what would be the way of echoing the change thoughout your database?
My gut reaction for the answers are
1) performance will decrease as effectively the dbms has to "parse" every insert/update to a UDT field in a different method.
2) create a new udt and alter any tables referencing the old one before dropping it.
What do we think?

Hello
Is there a way that I can create a user defined variable in my database? I have a fairly large chunk of xml that I would like to store in the database that can be updated by clients ( in rare cases ). I could use other mechinisms to allow access to it, but all other application related information is stored nicely in this one place, I hate to vary for this single piece.
Thank you for your time and thoughts.
Patrick

When I define a UDF in SQL 2000 I can't execute it without qualifiction. Here's the code:
CREATE FUNCTION GetLastShipDate(@DO_No CHAR(10))
RETURNS CHAR(10)
-- DROP FUNCTION GetLastShipDate
BEGIN
DECLARE @v_last_ship_date CHAR(10)
SELECT @v_last_ship_date = COALESCE(CONVERT(CHAR(10), MAX(Asn.Asn_Ship_DateTime), 110), '')
FROM Asn,Asn_Do
WHERE Asn_Do.Asn_Number=Asn.Asn_Number
AND Asn_Do.DO_Number = @DO_No
AND Asn.ASN_STATUS in ('SENT','RESENT')
RETURN @v_last_ship_date
END
So I have to execute this with:
SELECT dbo.GetLastShipDate('T010215004')
I want to execute it with
SELECT GetLastShipDate('T010215004')
What am I doing wrong?

I create the following UDF just for learning purposes and I cannot seem to get it to return a value.
Stored Procedure
REATE PROCEDURE usp_GetXSection
@fWidth float,
@fHeight float,
@fResult float OUTPUT
AS
BEGIN
set @fResult = [dbo].[XSECTION](@fWidth, @fHeight)
END
GO
Ane the following UDF
CREATE FUNCTION XSECTION
(@Width float, @Height float)
RETURNS float
AS
BEGIN
RETURN (@Width * @Height)
END
I call it using ADO in a c++ application, but all returns empty
Any ideas? C++ code to follow.

void CFormTemplateSetup::OnCalculate()
{
_CommandPtr pCmd(__uuidof(Command));
_ParameterPtr pWidth(__uuidof(Parameter));
_ParameterPtr pHeight(__uuidof(Parameter));

try
{
pCmd->ActiveConnection = GetDocument()->GetConnection();
pCmd->CommandText = _T("usp_GetXSection");
pCmd->CommandType = adCmdStoredProc;
_variant_t vWidth, vHeight;
vWidth.vt = VT_R4;
vHeight.vt = VT_R4;
vWidth.fltVal = 10;
vHeight.fltVal = 10;
pWidth = pCmd->CreateParameter(_T("@fWidth"), adInteger, adParamInput, sizeof(int), vWidth);
pHeight = pCmd->CreateParameter(_T("@fHeight"), adInteger, adParamInput, sizeof(int), vHeight);
