I have some code that I need to run every quarter. I have many that are similar to this one so I wanted to input two parameters rather than searching and replacing the values. I have another stored procedure that's executed from this one that I will also parameter-ize. The problem I'm having is in embedding a parameter in the name of the called procedure (exec statement at the end of the code). I tried it as I'm showing and it errored. I tried googling but I couldn't find anything related to this. Maybe I just don't have the right keywords. what is the syntax?
CREATE PROCEDURE [dbo].[runDMQ3_2014LDLComplete] @QQ_YYYY char(7), @YYYYQQ char(8) AS begin SET NOCOUNT ON; select [provider group],provider, NPI, [01-Total Patients with DM], [02-Total DM Patients with LDL],
Hello, since a couple of days I'm fighting with RS 2005 and the Stored Procedure.
I have to display the result of a parameterized query and I created a SP that based in the parameter does something:
SET ANSI_NULLS ON SET QUOTED_IDENTIFIER ON CREATE PROCEDURE [schema].[spCreateReportTest] @Name nvarchar(20)= ''
AS BEGIN
declare @slqSelectQuery nvarchar(MAX);
SET NOCOUNT ON set @slqSelectQuery = N'SELECT field1,field2,field3 from table' if (@Name <> '') begin set @slqSelectQuery = @slqSelectQuery + ' where field2=''' + @Name + '''' end EXEC sp_executesql @slqSelectQuery end
Inside my business Intelligence Project I created: -the shared data source with the connection String - a data set : CommandType = Stored Procedure Query String = schema.spCreateReportTest When I run the Query by mean of the "!" icon, the parameter is Prompted and based on the value I provide the proper result set is displayed.
Now I move to "Layout" and my undertanding is that I have to create a report Paramater which values is passed to the SP's parameter... So inside"Layout" tab, I added the parameter: Name allow blank value is checked and is non-queried
the problem is that when I move to Preview -> I set the value into the parameter field automatically created but when I click on "View Report" nothing has been generated!!
I had thought that this was possible but I can't seem to figure out the syntax. Essentially I have a report where one of the parameters is populated by a stored procedure.
Right now this is easily accomplished by using "exec <storedprocname>" as the query string for the report parameter. However I am not clear if it is possible to now incorporate User!UserID as parameter to the stored procedure. Is it? Thanks
Has anyone encountered this before? Procedure or Function 'stored procedure name' expects parameter '@parameter', which was not supplied. It seems that my code is not passing the parameter to the stored procedure. When I click this hyperlink: <asp:HyperLink ID="HyperLink1" Runat="server" NavigateUrl='<%# "../Division.aspx?CountryID=" + Eval("CountryID")%>' Text='<%# Eval("Name") %>' ToolTip='<%# Eval("Description") %>' CssClass='<%# Eval("CountryID").ToString() == Request.QueryString["CountryID"] ? "CountrySelected" : "CountryUnselected" %>'> </asp:HyperLink> it is suppose to get the country name and description, based on the country id. I am passing the country id like this. protected void Page_Load(object sender, EventArgs e) { PopulateControls(); } private void PopulateControls() { string countryId = Request.QueryString["CountryID"]; if (countryId != null) { CountryDetails cd = DivisionAccess.GetCountryDetails(countryId); divisionNameLabel.Text = cd.Name; divisionDescriptionLabel.Text = cd.Description; } } To my app code like this: public struct CountryDetails { public string Name; public string Description; } public static class DivisionAccess { static DivisionAccess() public static DataTable GetCountry() { DbCommand comm = GenericDataAccess.CreateCommand(); comm.CommandText = "GetCountry"; return GenericDataAccess.ExecuteSelectCommand(comm); } public static CountryDetails GetCountryDetails(string cId) { DbCommand comm = GenericDataAccess.CreateCommand(); comm.CommandText = "GetCountryDetails"; DbParameter param = comm.CreateParameter(); param.ParameterName = "@CountryID"; param.Value = 2; param.DbType = DbType.Int32; comm.Parameters.Add(param); DataTable table = GenericDataAccess.ExecuteSelectCommand(comm); CountryDetails details = new CountryDetails(); if (table.Rows.Count > 0) { details.Name = table.Rows[0]["Name"].ToString(); details.Description = table.Rows[0]["Description"].ToString(); } return details; }
As you can see I have two stored procedures I am calling, one does not have a parameter and the other does. The getcountry stored procedure returns the list of countries in a menu that I can click to see the details of that country. That is where my problem is when I click the country name I get Procedure or Function 'GetCountryDetails' expects parameter '@CountryID', which was not supplied Someone please help!
I have this update procedure that updates and encrypts a credit card column. I added the pass phrase to a table and now I'm trying to use that pass phrase in my update procedure. When I run the update from the app the error is that the procedure is not getting the @Phrase parameter. Can anyone see why this might be?ALTER PROCEDURE [dbo].[UpdatePayment]
i need to run a stored procedure from an asp page that will import data into a temporary table.
i am having trouble with passing the parameter from the Exec command (currently developing in QA). It works ok where i want to use a value such as 'PC', or 'printer' or 'laptop' where the import sql has a where clause of '... = <<parameter>>...'.
I want however to be able to pass it a value such as ['printer','laptop','pc']so that the procedure will collect the data into the temp table with an '...in <<parameter>>'
this falls over and retrieves zero rows. the parameter is passed to the sp correctly as i have used a print command to display it, it comes back as 'pc',printer','laptop'. It appears to be the ' in ' that is not parsing the parameter.
I have a problem when i want to construct a stored procedure. I want to pass a parameter with customerid's. The problem is that I donīt know how many customerId's I send to the stored procedure, because the user select the customerId's from a selectbox. The SQL string I want to excute looks like this
SELECT CustomerName FROM Customer WHERE CustomerId IN (199, 301, 408... )
How should I create the stored procedure so I put the customerId values in a parameter, like the procedure below? (I know that this not will work)
CREATE PROCEDURE rpt_PM2000_test(@SCustomerId varChar) AS BEGIN SELECT Customer FROM Customer WHERE CustomerId IN (@sCustomerId) END
In the Create portion of a stored procedure, does the line in bold mean that if the parameter @RegoDate is not provided, then use the current datetime?
I have an Access front end/MSDE2000 backend system. There is a form that has a subform which is based on the results of a stored procedure. Both my subform and mainform contain intOrderID ( which is the field i want to link both of them with ).
I would like to have the subform's data updated when changing records in the mainform. In Access, this was simple ( link child and master fields ), but not with MSDE2000 as a back end ( ADO connection thing...)
I think i have to create something to filter the results of the stored procedure, but i dont like the fact the the entire dataset needs to be transmitted over the network ( most of the time, users will only be creating new records, or reviewing recently created ones )
I'm really not sure as to how to accomplish this... Any ideas?

I'm trying to create a SP with a parameter for server.
CREATE PROCEDURE dbo.sp_Testing @server ???????
AS
SELECT * from @server
GO
Does anyone know how to do what i'm trying here..??? I don't know the type of the parameter...is it just simply server? or is there another specific name for it??? thanks,
I'm attempting to return a value from my stored procedure. Here is my button click event that runs the stored procedure. protected void btn_Move_Click(object sender, EventArgs e) { /*variables need for the update of the old staff record and the creation of the new staff record. */ BMSUser bmsUser = (BMSUser)Session["bmsUser"]; int staffid = Convert.ToInt32(bmsUser.CmsStaffID); int oldStaffProfileID = Convert.ToInt32(Request.QueryString["profileid"]); string newManager = Convert.ToString(RadComboBox_MangersbyOrg.Text); int newMangerProfileID = Convert.ToInt32(RadComboBox_MangersbyOrg.Value);
SqlParameter sp = new SqlParameter("@OLDManagerReturn", SqlDbType.Int); sp.Direction = ParameterDirection.Output; cmd.Parameters.Add(sp);
lbl_ERROR.Text = Convert.ToString(sp);
conn.Open(); SqlTransaction trans = conn.BeginTransaction(); cmd.Transaction = trans; cmd.ExecuteNonQuery(); conn.Close(); My parameter sp is coming back null for some reason. Am I not setting the parameter correctly? I set a break point and it says the value is null. Here is the parts of my stored proc returning the value... DECLARE @OLDManagerReturn numeric(9) SELECT @OLDManagerReturn = ManagerProfileID FROM tblBMS_Staff_rel_Staff WHERE StaffProfileID = @OldStaffProfileID AND Active=1 AND BudgetYear = @BudgetYear RETURN @OLDManagerReturn
In the SqlDbType enumeration there is no value for the new (max) types, only varchar. If Im passing a large string, it will get cut off at 8K. So how do I specify my varchar parameter as being of the max type ?
Hi,This works:CREATE PROCEDURE MyProc @Date smalldatetime = '2005-01-01'AS... But this does not CREATE PROCEDURE MyProc @Date smalldatetime = GETDATE()AS... I'm talking about sql2005. Can anyone help how to overcome this?
How do I assign a temp value to a parameter in a stored procedure? I am trying like so: Alter PROCEDURE ap_Insert_Pricing_ListPrice @partNumber varchar = "CQ2"AS SELECT PartNumber FROM Pricing WHERE (PartNumber = @partNumber)GO What is the correct way to assign a temp value for testing purposes in SQL Server 2000 Query Analyzer? When I try: Alter PROCEDURE ap_Insert_Pricing_ListPrice @partNumber varchar AS Set @partNumber = "10-AF40-N04B-JZ"SELECT PartNumber FROM Pricing WHERE (PartNumber = @partNumber)GO I get error: Invalid column name '10-AF40-N04B-JZ'.

I have a stored procedure that inserts a new record, and returns the ID value for the newly inserted record. The procedure works fine, but I'm unable to get that return value in my code. Here's what I have: IF OBJECT_ID ( 'dbo.dbEvent', 'P') IS NOT NULL DROP PROCEDURE dbEvent GO CREATE PROCEDURE @Name varchar(200) ,@Location varchar(200) AS INSERT INTO Event ( NAME , LOCATION ) VALUES ( NAME , @LOCATION ) SELECT SCOPE_IDENTITY()
And my code behind: public Int64 Insert(SqlConnection Conn) { try { using (SqlCommand Command = new SqlCommand("dbo.dbEvent", Conn)) { Command.CommandType = CommandType.StoredProcedure; Command.Parameters.Add("@ID", ID).Direction = ParameterDirection.Output; Command.Parameters.Add("@NAME", SqlDbType.VarChar, 200).Value = PermitName; Command.Parameters.Add("@LOCATION", SqlDbType.VarChar, 200).Value = Location; if (Conn.State != ConnectionState.Open) Conn.Open(); Command.ExecuteNonQuery(); Int64 _requestId = Convert.ToInt64(Command.Parameters.Add("@ID", SqlDbType.BigInt).Value.ToString()); return _requestId; } I'm getting the error that I have "Too many arguments specified" in my Insert() method. When I test the procedure in Query Analyzer, it works fine and returns the correct value. Any suggestions? Don't I need to declare that return value in my .NET code as an output parameter?
WHERE ltrim(str((DATEPART(yyyy, dbo.Media_Tracking_Ad_History.ADDATE))) IN ('2003','2004','2005'))
This doesn't:
WHERE WHERE ltrim(str((DATEPART(yyyy, dbo.Media_Tracking_Ad_History.ADDATE))) IN (@strYears))
@strYears will work if I only pass a single value such as 2003. I've tried every combination of single and double quotes I can think of to pass multiple values but nothing works. Any suggestions?
Hey huys, I got this stored procedure. First of all: could this work?
--start :) CREATE PROCEDURE USP_MactchUser
@domainUserID NVARCHAR(50) ,
@EmployeeID NVARCHAR(50) ,
@loginType bit = '0' AS
INSERT INTO T_Login
(employeeID, loginType, domainUserID)
Values (@EmployeeID, @loginType, @domainUserID) GO --end :)
then I got this VB.Net code in my ASP.net page....
---begin :) Private Sub matchUser() Dim insertMatchedUser As SqlClient.SqlCommand Dim daMatchedUser As SqlClient.SqlDataAdapter SqlConnection1.Open() 'conn openned daMatchedUser = New SqlClient.SqlDataAdapter("USP_MatchUser", SqlConnection1) daMatchedUser.SelectCommand.CommandType = CommandType.StoredProcedure daMatchedUser.SelectCommand.Parameters.Add(New SqlClient.SqlParameter("@EmployeeID", SqlDbType.NVarChar, 50)) daMatchedUser.SelectCommand.Parameters.Add(New SqlClient.SqlParameter("@domainUserID", SqlDbType.NVarChar, 50)) daMatchedUser.SelectCommand.Parameters("@EmployeeID").Value = Trim(lblEmployeeID.Text) daMatchedUser.SelectCommand.Parameters("@domainUserID").Value = Trim(lblDomainuserID.Text) daMatchedUser.SelectCommand.Parameters("@EmployeeID").Direction = ParameterDirection.Output daMatchedUser.SelectCommand.Parameters("@domainUserID").Direction = ParameterDirection.Output SqlConnection1.Close() 'conn closed
End Sub ---
If I try this it doesn't work (maybe that's normal :) ) Am I doing it wrong. The thing is, in both label.text properties a values is stored that i want to as a parameter to my stored procedure. What am I doing wrong?
What i want is to add by parameter a Where clause and i can not find how to do it!CREATE PROCEDURE [ProcNavigate]( @id as int, @whereClause as char(100))ASSelect field1, field2 from table1 Where fieldId = @id /*and @WhereClause */GOany suggestion?
Hi I have an if clause in my code to add the final parameter value to send to the database. If Page.User.IsInRole("MICMS") Then cmdCheckUser.Parameters.Add("@C_ID", 0) Else cmdCheckUser.Parameters.Add("@C_ID", Session("C_ID")) End If
If the user is in the role, the error is triggered saying that @C_ID is expected by the stored procedure. If i then change the value from 0 to 10, the stored procedure works fine.Is there any reason that the stored procedure is failing when the value 0 is used and not when any other value is used?Thanking you in advance.
I have a SQL Server 2005 Stored Procedure that takes a parameter to sort on: ----------------------------------------------------------------- ALTER PROCEDURE [dbo].[GetAllApplications_Sorted]

And I can't figure out why...
If you have a table called Person and has ID, Age, Gender and Name. And you have a stored procedure: CREATE PROCEDURE [dbo].[GetName]@Age TINYINT,@Gender TINYINTASBEGIN SELECT Name FROM Person WHERE Age = @Age AND Gender = @Gender END You want some times to send @Age as null to get all ages (or in other words, you are not concerned with the age) or @Gender as null to get all genders. A way to do that is to build your query string dynamically and execute it with EXEC command. However, this is a bad solution because you are losing most of the SP benefits and writting longer and more complicated procedures, specially that you have a lot of parameters! Another solution that I thought of is having your select like this: SELECT Name FROM Person WHERE Age = ISNULL(@Age,Age) AND Gender = ISNULL(@Gender, Gender) However, I noticed that when the value of the column is NULL, you will get false results, obviously because you are using = operator in comparing a value with null while you should be using IS operator, so this method did not work. I am wondering if any one has a good solution for this. Adam Tibi
This should be relatively easy but for some reason it isn't. I'm trying to simply add parameters to a stored procedure that performs a simple input and I can't do it... I keep getting an error that the parameters are not found when I am explicitly stating them. I could do this with VB ASP.NET 1.x but with all these radical changes with 2.0, I'm pulling my hair out....

can we use output parameter with insert query in stored procedure. suppose we insert a record and we want to get the id column of this record which is identity column. we want to get this value in output parameter. ie insert record and get its id column value in output parameter.
I have been converting a VB 6 applications database queries into SQL Server 2000 stored procedures and have come up against a problem where lists are used in search conditions...For example a list of accounts are selected based on their account currency ID being equal to 1, 5, or 7. In the VB 6 query the string looks like....
SELECT tblAccount.txtName FROM tblAccount WHERE (tblAccount.intCurrencyId IN(1, 5, 7))
The list could contain a single value or upto 20 values. Is it possible to pass the currency list (i.e "1, 5, 7, ...") as a parameter to the stored procedure?
I am using the MS SQL Server Management Studio Express to create a stored procedure in one of my databases. I specify one of the parameters as OUTPUT as follows:
set ANSI_NULLS ON set QUOTED_IDENTIFIER ON GO
ALTER PROCEDURE [dbo].[ProcRetDbl]
@Threshold real, @Result real OUTPUT AS BEGIN
SET NOCOUNT ON;
SELECT @Result = Channel1 FROM DataTable WHERE Channel2 < @Threshold END
But then when I look at the properties of the @Result parameter in the Object Explorer's tree, it is shown as "Input/Output". Now, this seems like no problem at all since it will work fine as output, even though I don't need it to be able to do input as well, but I'm wondering why that is happening.
I am using ADO.Net on the other end to execute the procedure and I need to decide what parameter type to set to the SqlParameter object: "Output" or "InputOutput". I'm sure I can sort this out but I usually like to know what I'm doing. Thanks for the help.
Now, I like #1 because the implementation is simple -- the calling code simply passes an author name, and a country id and an INSERT INTO statement is called with those parameters
INSERT INTO authors( @authorName, @countryId )
I like #1, because it hides the surrogate "id" key from the application calling code. But on the downside, it has more overhead work, because you have to first a) verify a country with that name exists, and b) select that id into a variable.
DECLARE id INT; IF EXISTS (select * from countries where country_id = @countryId ) THEN SELECT country_id INTO id FROM countries WHERE country_name = @countryName; END IF;
(Sorry I may have the SQL syntax wrong up there, but I was just trying to demonstrate the extra overhead involved).
