How To Specify Input Parameters?

Oct 16, 2006

I'm very new to SQL Server so please forgive me if this question is ridiculously simple. I have to upgrade the report engine from one that was used in a legacy VB6 app to a C#.net app. In doing so, I'm looking at assorted reports that came out of the old app. Here is the SQL code for one of them:

SELECT (LTRIM(STR(From_To,10,0)) + '-' + LTRIM(STR(From_To + 49,10,0))) AS Bonus_Earned, COUNT (Empl_ID) AS Men, round(SUM (SumDollars),2) AS Group_Earn, round((SUM (SumDollars) / COUNT (Empl_ID)),2) AS Calc0 FROM (SELECT CONVERT (int, round (SumDollars / 50, 2)) * 50 AS From_To, SumDollars, Empl_ID FROM (SELECT round(SUM (Actual_Hours_Dollars.Incentivedollars * Contract_History.Bonus_Pct / 100), 2) AS SumDollars, employees.Empl_ID FROM ((Employees INNER JOIN Actual_hours_dollars ON Employees.Empl_ID = Actual_Hours_Dollars.Empl_ID_R) INNER JOIN Contracts ON Actual_Hours_Dollars.Contract_ID = Contracts.Contract_No) INNER JOIN Contract_History ON Contracts.Contract_Idx = Contract_History.Contract_Idx_R where employees.empl_idx = (SELECT max(empl_idx) FROM Employees AS OuterEmployees WHERE OuterEmployees.empl_id = employees.empl_id AND outeremployees.Datex = (SELECT max(datex) FROM Employees AS InnerEmployees WHERE InnerEmployees.empl_id = employees.empl_id AND Inneremployees.disabled = 0 AND Inneremployees.Datex < '~EndDate~')) AND Contracts.Datex = (SELECT max(datex) FROM Contracts AS InnerContracts WHERE InnerContracts.contract_no = Contracts.contract_no AND InnerContracts.disabled = 0 and InnerContracts.deleted = 0 AND InnerContracts.Datex < '~EndDate~') AND Actual_hours_dollars.Datex >= '~StartDate~' AND Actual_Hours_Dollars.Datex < '~EndDate~' AND dateadd(month, Contract_History.Monthx - 1, dateadd(year, Contract_History.Yearx - 1900, '01 Jan 1900')) >= '~StartDate~' AND dateadd(month, Contract_History.Monthx - 1, dateadd(year, Contract_History.Yearx - 1900, '01 Jan 1900')) < '~EndDate~' and Actual_Hours_Dollars.IncentiveHours <> 0 GROUP BY employees.empl_ID) AS InnerRS1 GROUP BY ROUND (SumDollars * 2, -2) /2, SumDollars, Empl_ID) AS InnerRS2 GROUP BY From_To

I'm only including it for completeness. The key thing I'd like to draw your attention to are two variables that are clearly input parameters: ~StartDate~ and ~EndDate~.

My question is this: If I want to copy this code into SQL Query Analyzer and run it to see what kind of results I get back, what's the simplest way to define these two input parameters? I'm hoping you could just show me the syntax to define them above the SELECT statement.

Parameters Input Field Size

Jul 2, 2007

Hi,



is it possible to change the appearence of input fields for parameters on the report server? My parameter is Multi-value with quite large amount of available values. On report server, user can (without scrolling) see only the first value. Parameter values are quite long, so user has to move alternally with both vertical and horizontal scrollbars to find the right value.



Thanks

Insert Syntax When Passing Input Parameters

Dec 27, 2000

I'm trying something like this:

CREATE PROCEDURE Add_Junk @Dist char, @CheckNo int =null OUTPUT AS
Set NoCount On
BEGIN TRANSACTION
INSERT INTO Junk (Dist)
VALUES (@Dist)
COMMIT TRANSACTION
select @CheckNo=@@IDENTITY

If what I pass is "416" I only get the "4" in my database and nothing else.
I don't get an error message.
What is wrong with my syntax?

PS I'm using Microsoft SQL 7.0

T-SQL (SS2K8) :: First And Last Day Prior Month As Input Parameters

Apr 16, 2014

I have to create a report and I want all activity for the previous month.

I need to calculate the First and Last Day Prior Month to be used as Input Parameters.

Would something like this be the case or is there a better solution?

[code="sql"]
SELECT DATEADD(month, DATEDIFF(month, -1, getdate()) - 2, 0) as FirstDayPreviousMonthWithTimeStamp,
DATEADD(ss, -1, DATEADD(month, DATEDIFF(month, 0, getdate()), 0)) as LastDayPreviousMonthWithTimeStamp
[/code]

I was thinking get the first day of the previous and current month to exclude the Timestamp and use a less then first day of current month?

if param1 <> null

Select *
from table
where id = param1

else

Select *
from table
where id = param2

end if

Thanks in advance....

SSIS Web Service Task Input Parameters

Nov 7, 2006

There is not a way to pass parameters to input of Web Service tasks. I heard this problem is fixed with SQL2K5 SP1 and even the online doc says that one can choose either "value" or "variable" when specifying input for web service tasks, but after I installed what-I-think-is SP1, there is still no way to do this.

If one can only specify values (hard-coded) as input to web service tasks, then this would be a very severe limitation. I hope I'm wrong, so could someone please give a pointer. Thanks

SQL Server 2012 :: Stored Procedure With One Or More Input Parameters?

Dec 17, 2013

I've been tasked with creating a stored procedure which will be executed after a user has input one or more parameters into some search fields. So they could enter their 'order_reference' on its own or combine it with 'addressline1' and so on.

What would be the most proficient way of achieving this?

I had initially looked at using IF, TRY ie:

IF @SearchField= 'order_reference'
BEGIN TRY
select data
from mytables
END TRY

However I'm not sure this is the most efficient way to handle this.

Stored Procedures Management - Keeping Input Parameters Updated

Dec 4, 2003

Hi everyone

I have just starting creating some stored procedures for our system and have a question related to management of these.

When using input parameters using the following syntax:

CREATE PROCEDURE sp_someInputProcedure
@Username as varchar(16)
@Password as varchar(12)
@Name as varchar(50)
@Address as varchar(60)
@Zip as int
@City as varchar(30)
...
etc.

This is all well and good, but what if I make a change in the datamodel - for instance changing a datatype or the length of a varchar - do I need to remember to manually update all stored procedures that uses these columns/variables?

Seems like a bit of a hazzle. Is there an easier way to do this?

Many thanks,

1 SP With Dynamic Input Parameters And Multiple Rows As The Source Of The Query

Dec 4, 2005

How can I run a single SP by asking multiple sales question eitherby using the logical operator AND for all the questions; or usingthe logical operator OR for all the questions. So it's alwayseither AND or OR but never mixed together.We can use Northwind database for my question, it is very similarto the structure of the problem on the database I am working on.IF(SELECT OBJECT_ID('REPORT')) IS NOT NULLDROP TABLE REPORT_SELECTIONGOCREATE TABLE REPORT_SELECTION(AUTOID INT IDENTITY(1, 1) NOT NULL,REPSELNO INT NOT NULL, -- Idenitifies which report query this-- "sales question" is part ofSupplierID INT NOT NULL, -- from the Suppliers tableProductID INT NOT NULL, -- from the Products table, if you choose--a ProductID, SupplierID is selected also by inheritenceCategoryID INT NOT NULL, -- from the Categories tableSOLDDFROM DATETIME NULL, -- Sold from which dateSOLDTO DATETIME NULL, -- Sold to which dateMINSALES INT NOT NULL, -- The minimum amount of salesMAXSALES INT NOT NULL, -- The maximum amount of salesOPERATOR TINYINT NOT NULL -- 1 is logical operator AND, 2 is OR)GOINSERT INTO REPORT_SELECTIONSELECT 1, 1, 2, 1, '1/1/1996', '1/1/2000', 10, 10000, 1 UNION ALLSELECT 1, -1, -1, 1, '1/1/1996', '1/1/2000', 10, 1000, 1You can ask all kinds of sales questions like:1-I want all employees that sold products from supplierID 1(Exotic Liquids), specifically the ProductID 2 (Chang) from theCategoryID 1 (Beverages) between Jan 1 1996 to Jan 1 2000 and soldbetween $10 and $10000 - AND for my 2nd sales question2-I want all employees that sold CategoryID 1 (beverages) betweenJan 1 1996 to Jan 1 2000 and sold between $10 and $1000I want to get the common result of both questions and find outwhich employee(s) are in this list.Here are some of the points:1-I want my query to return the list of employees fitting theresult of my sales question(s).2-If I ask three questions with the logical operator AND, I wantthe list of employees that are common to all three questions.3-If I ask 2-3-4. questions with the logical operator OR, I wantthe list of employees that are in the list of the 1st "successful"sales question (the first question that returns any employee isgood enough)4-You can ask all kind of sales question you want even if theycontradict each other. The SP should still run and returnnothing if that is the case.5-Let's assume you can have the same product name from the samesupplier but under different categories. So entering a ProductIDshould not automatically enter the CategoryID also; whereasentering the ProductID should automatically enter its SupplierID.6-SOLDFROM, SOLDTO, MINSALES, MAXSALES, OPERATOR are mandatoryfields, you can't leave them NULL7-SupplierID, ProductID and CategoryID are the dynamic inputparameters, there can be 5 different combinations to choose from:a-SupplierID onlyb-SupplierID and a ProductID,c-SupplierID and a CategoryIDd-SupplierID, ProductID and a CategoryIDe-CategoryID onlyf-Any time you choose a ProductID, the SupplierID valuewill be filled automatically based on the ProductID'srelationshipg-Any of the three values here that is not chosen by theuser will take a default value of -1 (meaning return ALLfor this Column, in other words don't filter by this column)The major problem I have is I can't use dynamic SQL for choosingthe three dynamic columns as the 2nd row of records would have adifferent selection of dynamic columns (at least I don't know howif the solution is dynamic SQL). The only solution I can think oflooks pretty bad to me. I would use a cursor, run each row at atime, store a TRUE, FALSE value to stop processing or not andstore the result in another detail table. Then if all ANDquestions have ended with TRUE do a union of all the result andreturn the common list of employees. It sounds pretty awful as anapproach. I am hoping there's a simpler method for achieving this.Does anyone know if any SQL book has a topic on this type ofquery? If so I'll definitely buy the book.I appreciate any help you can provide.Thank you

Sniffing StoredProc Input Parameters For General Error Handling

Dec 10, 2007

Hi,

id beg for a hint if our idea of a general dynamic CATCH handler for SPs is possible somehow. We search for a way to dynamically figure out which input parameters where set to which value to be used in a catch block within a SP, so that in an error case we could buld a logging statement that nicely creates a sql statement that executes the SP in the same way it was called in the error case. Problem is that we currently cant do that dynamically.

What we currently do is that after a SP is finished, a piece of C# code scans the SP and adds a general TRY/CATCH bloack around it. This script scans the currently defined input parameters of the SP and generates the logging statement accordingly. This works fine, but the problem is that if the SP is altered the general TRY/CATCH block has to be rebuildt as well, which could lead to inconstencies if not done carefully all the time. As well, if anyone modifies an input param somewhere in the SP we wouldnt get the original value, so to get it right we would have to scan the code and if a input param gets altered within the SP we would have to save it at the very beginning.

So the nicer solution would be if we could sniff the input param values dynamically on run time somehow, but i havent found a hint to do the trick.....

Any tipps would be appreciated...

cheers,
Stefan

Execute SQL Task : Input And Output Parameters In Tsql Stataments With ADO.NET Connection Type

Jan 2, 2007

Hi Everyone,

I haven't been able to successfully use the ADO.NET connection type to use both input and output parameters in an execute sql task containing just tsql statements (no stored procedure calls). I have successfully used input parameters on their own but when i combine it with output parameters it fails on the simplest of tasks.

I would really find it beneficial if you could use the flexibility of an ADO.NET connection type as the parameter marker and parameter name can be referenced anywhere throughout the sql statement in no particular order. The addition of an output parameter would really make it great!!

Thanks

Accessing A Stored Procedure From ADO.NET 2.0-VB 2005 Express:How To Define/add 1 Output &&amp; 2 Input Parameters In Param. Coll.?

Feb 23, 2008

Hi all,

In a Database "AP" of my SQL Server Management Studio Express (SSMSE), I have a stored procedure "spInvTotal3":

CREATE PROC [dbo].[spInvTotal3]

@InvTotal money OUTPUT,

@DateVar smalldatetime = NULL,

@VendorVar varchar(40) = '%'



This stored procedure "spInvTotal3" worked nicely and I got the Results: My Invoice Total = $2,211.01 in
my SSMSE by using either of 2 sets of the following EXEC code:
(1)
USE AP
GO
--Code that passes the parameters by position
DECLARE @MyInvTotal money
EXEC spInvTotal3 @MyInvTotal OUTPUT, '2006-06-01', 'P%'
PRINT 'My Invoice Total = $' + CONVERT(varchar,@MyInvTotal,1)
GO
(2)
USE AP
GO
DECLARE @InvTotal as money
EXEC spInvTotal3
@InvTotal = @InvTotal OUTPUT,
@DateVar = '2006-06-01',
@VendorVar = '%'
SELECT @InvTotal
GO
////////////////////////////////////////////////////////////////////////////////////////////
Now, I want to print out the result of @InvTotal OUTPUT in the Windows Application of my ADO.NET 2.0-VB 2005 Express programming. I have created a project "spInvTotal.vb" in my VB 2005 Express with the following code:


Imports System.Data

Imports System.Data.SqlClient

Imports System.Data.SqlTypes

Public Class Form1

Public Sub printMyInvTotal()

Dim connectionString As String = "Data Source=.SQLEXPRESS; Initial Catalog=AP; Integrated Security=SSPI;"

Dim conn As SqlConnection = New SqlConnection(connectionString)

Try

conn.Open()

Dim cmd As New SqlCommand

cmd.Connection = conn

cmd.CommandType = CommandType.StoredProcedure

cmd.CommandText = "[dbo].[spInvTotal3]"

Dim param As New SqlParameter("@InvTotal", SqlDbType.Money)

param.Direction = ParameterDirection.Output

cmd.Parameters.Add(param)

cmd.ExecuteNonQuery()

'Print out the InvTotal in TextBox1

TextBox1.Text = param.Value

Catch ex As Exception

MessageBox.Show(ex.Message)

Throw

Finally

conn.Close()

End Try

End Sub

End Class
/////////////////////////////////////////////////////////////////////
I executed the above code and I got no errors, no warnings and no output in the TextBox1 for the result of "InvTotal"!!??
I have 4 questions to ask for solving the problems in this project:
#1 Question: I do not know how to do the "DataBinding" for "Name" in the "Text.Box1".
How can I do it?
#2 Question: Did I set the CommandType property of the command object to
CommandType.StoredProcedure correctly?
#3 Question: How can I define the 1 output parameter (@InvTotal) and
2 input parameters (@DateVar and @VendorVar), add them to
the Parameters Collection of the command object, and set their values
before I execute the command?
#4 Question: If I miss anything in print out the result for this project, what do I miss?

Please help and advise.

Thanks in advance,

I have a SSRS report with four parameters,and I want to be able to enter information for two of the parameters and run the report opposed to all four of them. However, when I select allow blanks and only select the parameters that I want to run the report by, the report come back blank..Essentially, I want to be able to the run report by different parameters without having to enter information for all parameters at the same time.

Query Duration Using Parameters Vrs No Parameters

Apr 27, 2006

Hi,
I have an app in C# that executes a query using SQLCommand and parameters and is taking too much time to execute.

I open a SQLProfiler and this is what I have :

exec sp_executesql N' SELECT TranDateTime ... WHERE CustomerId = @CustomerId',
N'@CustomerId nvarchar(4000)', @CustomerId = N'11111

I ran the same query directly from Query Analyzer and take the same amount of time to execute (about 8 seconds)

I decided to take the parameters out and concatenate the value and it takes less than 2 second to execute.

Here it comes the first question...
Why does using parameters takes way too much time more than not using parameters?

Then, I decided to move the query to a Stored Procedure and it executes in a snap too.
The only problem I have using a SP is that the query can receive more than 1 parameter and up to 5 parameters, which is easy to build in the application but not in the SP

I usually do it something like
(@CustomerId is null or CustomerId = @CustomerId) but it generate a table scan and with a table with a few mills of records is not a good idea to have such scan.

Is there a way to handle "dynamic parameters" in a efficient way???

Parameters Dependencies When Using Parameters!Name.Label

Mar 7, 2007

Hello:

I just recently bumped into this problem and I think I know what's causing it. This is the setup:

Report Parameters: FromDate, ToDate, DivisionalOffice, Manager, SalesRep

dsCalendarEvents Parameters: FromDate.Value, ToDate.Value, DivisionalOffice.Value,

dsDivisions Parameters: N/A

dsManager Parameters: DivisionalOffice.Value

dsSalesRep: DivisionalOffice.Label

When I query the ReportServices WS and scan the parameter dependencies for SalesRep it says there are four dependencies: FromDate, ToDate, DivisionalOffice and Manager!!!

If I change "dsSalesRep" to use "DivisionalOffice.Value" the ReportingServices WS parameter dependency scan returns only one dependency for "SalesRep" parameter!!!( This is the correct behavior )

Has anybody seen this behavior and more importantly, is there a work around?

Table is created. I can SELECT * FROM accepted and see my column names.

Then I try to BCP into the table using:

C:>BCP sales..east in C:Resultsaccepted.txt -t -f C:cpformataccepted.fmt -Usa -Ppwd

I get this error:

Starting copy...
SQLState = 22001, NativeError = 0
Error = [Microsoft][ODBC SQL Server Driver]String data, right truncation
SQLState = 22001, NativeError = 0
Error = [Microsoft][ODBC SQL Server Driver]String data, right truncation

and so on......

In the .fmt file I've tried "", " ", " " and everthing I could think of as a delimiter. Still no luck. I've tried almost every switch available to both OSQL and BCP.
The data I am trying to BCP is a SQL result so I don't think any special delimiters are placed. I've tried not using the .fmt file and using the prompts but still no luck. Data is CAST in the query and doesn't excede 45 characters.
Hope I've explained my problem well enough.

Parameters.AddWithValue Vs. Parameters.Add

Jan 2, 2008

Hello all,
Given: 
string commandText = "Categories_Delete";SqlCommand myCommand = new SqlCommand(commandText, connection);myCommand.CommandType = CommandType.StoredProcedure;
   Is there a reason NOT to use myCommand.Parameters.AddWithValue("@CategoryID",CategoryID); I'd prefer to use that over  myCommand.Parameters.Add("@CategoryID", SqlDbType.Int, 4).Value = CategoryID; as I have these functions being created dynamically and hope to get away from a big lookup to try to convert System.Types into SqlDbTypes. [shudder]  
It seems that ADO.NET makes an implicit conversion to the valid type.  If this is correct then I can move on fat dumb and happy.  Anyone have any good insight?
Thanks,

Input Box Not Updating

Feb 25, 2008

I have two textboxes on the page...shipdate and duedate.  When the page loads, shipdate has today's date loaded and duedate has a date that's 28 days later than today.  When I change the dates and submit it's not updating in the database instead I'm getting the two dates in pageload.  What am I doing wrong?Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
 
ShipDateTxt.Text = Today()
DueDateTxt.Text = DateAdd(DateInterval.Day, 28, Today())
End SubProtected Sub LoanRequest_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles LoanRequest.Click
Dim conn As New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("TrainUserConnectionString").ConnectionString)Dim cmd As New Data.SqlClient.SqlCommandWith cmd
.Connection = conn
.CommandType = Data.CommandType.StoredProcedure
.CommandText = "UpdateloanerInfo".Parameters.AddWithValue("@requestorid", Integer.Parse(Request.QueryString("requestorid")))
.Parameters.AddWithValue("@shipdate", ShipDateTxt.Text).Parameters.AddWithValue("@duedate", DueDateTxt.Text)
End With
Here's updateloanerinfo stored procedure:
@requestorid int,@shipdate datetime,@duedate datetime
AS update LibraryRequest
set [shipdate] = @shipdate,[duedate] = @duedate
Where  requestorid=@requestorid

Can DTS Take Input Params?

Oct 13, 1999

Can I pass a parameter to a DTS package?


Here is what I am trying to do: Every month we need to import a fixed format text file into one of our tables. The format and location of the file is same every month except for the name. I want to create a DTS package to import it and call this DTS package first thing in a stored procedure(after which I do some processing with this imported data). I want to create the filename in my stored procedure and then call this DTS package to import it.

I am usig DTS as the interface is so much easier and want to avoid bcp :-)

Is it possible?

Thanks in advance,
Nishi

Input Masks???

Aug 29, 2000

I am just learning SQL Server and I am stuck with a few things. I was wondering if you can define input masks for columns in the database in SQL Server. I have used this feature many times in Access and on the front end in Oracle Forms. Is there such a thing in SQL Server?? Is it just called something different.....? I will be trying to format telephone numbers and dates. Thank you for you time.

Input On Training

May 8, 2007

Hi there,
I'll be going through a training couse for SQL Server next month. The class I'm signed up for is M2780: Maintaining a Microsoft® SQL Server™ 2005. My company uses SQL Server 2000 now and unless I give good reasons to upgrade to 2005, we won't be upgrading. I have very little DBA experience, but since I was told SQL Server is my responsibility, I figured it would make sense to go through some type of training for it. My questions are: Is there enough the same between the two that it makes sense for me to take this class? Are there good business reasons I can give for upgrading? If we don't upgrade is it worth taking a class for 2000 vs 2005?

Thanks for any input.

Passing Input

Oct 31, 2007

Need help.

I’m trying to pass inputs from one stored proc to another but I’m having problems in passing them.

First proc (input_passing) should pass the following inputs – FirstName, LastNmae and RecordID to the second proc (input_receive) – then the second proc will diplay the outcome – YES/NO if there is a match.
------------------------------------------------------------------------------------------
First proc (input_passing)
-------------------------------------------------------------------------------------------------------
DECLARE
@RecordIDVARCHAR(11),
@FirstNameVARCHAR(60),
@LastNameVARCHAR(60)


--DECLARE tbInputs CURSOR FOR
SELECT
RecordID,
FirstName,
LastName

FROM
tbInputs

OPEN tbInputs

FETCH NEXT FROM tbInputs
INTO @RecordID, @FirstName, @LastName

WHILE @@FETCH_STATUS = 0
BEGIN
--GET RECORD
SET @RecordID = RecordID from dbo.tbInputs)

END

FETCH NEXT FROM tbInputs
INTO @RecordID, @FirstName, @LastName

END

CLOSE tbInputs
DEALLOCATE tbInputs
exec input_receive
----------------------------------------------------------------------------------------------------------------- Second proc. (input_receive)

CREATE PROCEDURE input_receive
@RecordIDVARCHAR(11) = NULL,
@FirstNameVARCHAR(50) = NULL,
@LastNameVARCHAR(50) = NULL,
@RecordMatchBIT OUTPUT,
@MatchedOnVARCHAR(400) OUTPUT
AS

-- Declarations
DECLARE @CountINT
DECLARE@FoundBIT
DECLARE @AlertIDDECIMAL(18,0)
DECLARE@AlertCreateDateDATETIME
-- END Declarations

-- ******* Initializations **********
SET @Count = 0
SET @Found = 0
-- DEFAULT to No File Match
SET RecordMatch = 0
SET @MatchedOn = 'NO FOUND'
-- ******* END Initializations **********

-- First check to see if the RecordID Matches
IF( @RecordID IS NOT NULL AND @RecordID <> '' )
BEGIN
IF( CAST( REPLACE(@RecordID, '-', '') AS DECIMAL(18,0)) > 0 )
BEGIN
SELECT @Count = COUNT(*)
FROM tbAlert
WHERE REPLACE(RecordID, '-', '') = REPLACE(@RecordID, '-', '')

IF( @Count > 0 )
BEGIN
SET @RecordMatch = 1
SET @MatchedOn = 'FOUND : RecordID'
RETURN
END
END
END
