Retrieving Default Values For Parameters In A Stored Procedure.
Jul 23, 2005
I'm generating a list of parameters needed by stored procedures, and
I'd like to know which ones have default values assigned to them.
To retrieve the parameter information I use:
sp_sproc_columns @Procedure_Name='InsertUser''
However, the column that is supposed to give the default value,
'COLUMN_DEF' always returns as NULL, even when that column has a
default value assigned to it.
i.e.
CREATE PROCEDURE InsertUser
@UserID INT = 10,
.....
And then if I do a sp_sproc_columns @Procedure_Name='InsertUser'', the COLUMN_DEF value for the @UserID column is still NULL.
Does anyone know what I'm doing wrong and how I can retrieve the default value?
Please excuse me if this question has been asked before; I couldn’t find it. Perhaps someone could point me to the solution. A few years ago I wrote an order-entry application in classic ASP that I am now re-writing in ASP.NET 2.0. I am having very good success however I can’t figure out how to retrieve data from a stored procedure. I am using the FormView & SqlDataSource controls with a stored procedure to insert items into an order. Every time an item is inserted into the order the stored procedure does all kinds of business logic to figure out if the order qualifies for pricing promotions, free shipping, etc. If something happens that the user needs to know about the stored procedure returns a message with this line (last line in the SP) SELECT @MessageCode AS MessageCode, @MessageText AS MessageText I need to retrieve both the @MessageCode and the @MessageText values in my application. In classic ASP I retrieved these values by executing the SP with a MyRecordset.Open() and accessing them as normal fields in the recordset. In ASP.NET I have specified the SP as the InsertCommand for the SqlDataSource control. I have supplied all the parameters required by my SP and told the SqlDataSource that the insert command is a “StoredProcedure�. Everything actuly works just fine. The items are added to the order and the business logic in the SP works fine. I just have no way of telling the user that something important has happened. Does anyone know how I can pickup these values so that I can show them to my users? Bassicly if @MessageCode <> 0 I want to show @MessageText on the screen.
Hello, does anyone know how to determine (within the stored procedure)whether a parameter has been passed explicitly to a stored procedure asopposed to a parameter that has taken on the default value.Many thanksPhil
I have One package that it contains one Execute SQL task in that i have placed a Stored procedure . Now i want to pass values to Stored procedure parameters from a databse table by dynamically .For this i am trying to use " Script task " How can i pass that table column values to that stores procedure thru using Script Task?
A have a multi-valued parameter (B) which is dependent on a single-valued parameter (A) on my report. When a value is selected in A, I want all matching values in B to be selected by default and the "Select All" option checked. To do this I have set the Default Values section in B to point to the same dataset as the "Available Values" section. Both A and B have default values so the report runs automatically.
One of the values in parameter A (say Value1) yields more values in parameter B than the other (say Value2).
If I run the report the first time with Value1 selected as the default for parameter A, all values in B are checked correctly. If I run the report with Value2 selected the first time and then change the selected value to Value2 and run my report, all values in B are displayed but only the values that were previously checked (when Value1 was selected), are now checked, leaving the "Select All" unchecked.
What am I doing wrong? Why are all the values in B not checked? The dataset is the same in "Available Values" section and "Default Values" section.
This is regarding Report Services 2005 designing the report in Visual Studio.
Currently I am using a query to populate 2 date selectors in the parameter section at the top of a report. The start and end dates are determined by a query which returns the values based on yet another parameter. If I change the value of the paramter which is supposed to be used by the date selectors they don't seem to feel the need to re-calc themselves. I have 3 other dependent param's in the same report which behave reasonably.
Has anyone seen this before or is there way to somehow force a parameter re-caluclation?
I have created a report, and am setting default values for the parameters. Once the default parameters is set, the report automatically generates. Is there a way to make it not automatically generate the report? We are setting the parameters with values that will get the end user the most recent data, but alot of times, they will want to pull older data as well. We don't want them to have to wait for the report to automatically generate before they can change the parameter values
I created one stored proc, then copied it to create another similar stored proc with just some filtering changes in the second. Now I want to obtain the results from both like this:
ProjFee ProjGross DailyRunRate Var1 InHouse1 InHouse2 GrossGoal Group Name PostedAmount --------------------------------------------------------------------------------------------------------------------------- Row# 1 from current stored proc Row # 2 from called stored proc
so something like this I should get in the end for example when both results are combined:
The first stored proc (CurrentMonthCollections_AZ) attempts to include the results of the second stored proc at the end (CurrentMonthCollections_IL) by calling it and inserting the fields into a temp table.
I was told by Angel to instead convert the second stored proc into a UDF...but having trouble with this.
What is the best approach to get the desired 2 rows back that I need in that fasion?
Here is the code for the 2 stored procs (very long so I will post as as links):
Look at the end of CurrentMonthCollections_AZ.txt to see where I'm stuck in trying to select the results (ProjFee ProjGross DailyRunRate Var1 InHouse1 InHouse2 GrossGoal Var1 PostedAmount ) from both stored procs.
I don't think UNION is what I want because it will combine stuff...I just want 2 separated rows
I am trying to build an Sql page hit provider. I am having trouble getting a count back from the database. If I use ExecuteScalar it doesn't see any value in the returned R1C1. If I use ExecuteNonQuery with a @ReturnValue, the return value parameter value is always zero. Ideally I would like to use a dynamic stored proceudre if there are any suggestions for using them with C#. My table has rvPathName, userName and a date. I have the AddWebPageHit method working so I know data connection and sql support code in provider is working. I think the problem is either in how I am writing the stored procedures or how I am trying to retrieve the data in C#. Any help with this will be greatly appreciated.
Hi allI hv made a stored procedure which printsvarious messages using Print statement(shown in bold)------------------------------------------------------------------------------ .....if (@current_date<@ed) and (@current_date>@sd) begin print 'Date Lies Between Boundary Limits' select * from membership where uid=@uid end else begin if(@pipe=1) begin if(@plan_id=1) begin print 'Monthly Plan Activated' update membership set start_date=@opt_sd,end_date=DateAdd(M,1,@opt_sd),status=@opt,pipeline=0,user_option='',plan_id=null,download_limit=20 where uid=@uid select * from membership where uid=@uid end else begin print 'Weekly Plan Activated' update membership set start_date=@opt_sd,end_date=DateAdd(D,7,@opt_sd),status=@opt,pipeline=0,user_option='',plan_id=null,download_limit=10 where uid=@uid select * from membership where uid=@uid end end end --------------Now I want to retrieve the messages disp by these Print statements in my asp.net page where i m calling this stored proc.Pls suggest RegardsMunish
For a particular application i retrieve records using stored procedure and bind the same to the data grid and display the same. The data are fetched from a table say A joined with couple of tables to staisfy the requirement. Now this table A has around 3700000 + records. The Select statement is as
Select column1, column 2, column 3...................... column 25 from table A
inner join hash table D on A.Column3 = D.Column3 and A.Column4 = D.Column4 and a.nColumn1 = @ParameterVariable Inner join table B on a.nColumn1 =b.nColumn1 inner join table C on A.column2 = C.column2
Indices defined on A are IDX1 : Column 3, Column 4 IDX2 : Column 1
Around 350 records per second are inserted into the table A during the peak operation time. During this time when executing the procedure, it takes around 4 mins to fetch just 25000 records.
I need to fine tune the procedure. Please suggest me on same.
Hi all, From the "How to Call a Parameterized Stored Procedure by Using ADO.NET and Visual Basic.NET" in http://support.microsft.com/kb/308049, I copied the following code to a project "pubsTestProc1.vb" of my VB 2005 Express Windows Application:

Hi. I have a stored procedure "sp1" which returns a value (with the sql statement Return @ReturnValue). Is it possible for my asp.net page to retrieve this return value, and to do it declaratively (meaning without writing code to connect to the database in the code behind). If it is possible to do it like this please tell me how, and if not please tell me how to do it with code. Thanks in advance .
Hi, I'm at my wit's end with this. I have a simple stored procedure: PROCEDURE [dbo].[PayWeb_getUserProfile] ( @user_id_str varchar(36), @f_name varchar(50) OUTPUT)AS BEGINDECLARE @user_id uniqueidentifier; SELECT @user_id = CONVERT(uniqueidentifier, @user_id_str); select @f_name=f_name FROM dbo.tbl_user_profile WHERE user_id = @user_id; ENDRETURN The proc runs perfectly from the Management Console. In my ASP.net form (C#), the following always results in: "Invalid attempt to read when no data is present." (I'll highlight the line where the error results): SqlConnection conn = new SqlConnection(<connection string data>);SqlDataReader reader; SqlCommand comm = new SqlCommand("dbo.PayWeb_getUserProfile", conn);comm.CommandType = System.Data.CommandType.StoredProcedure; SqlParameter f_name = new SqlParameter("@f_name", SqlDbType.VarChar, 50); f_name.Direction = ParameterDirection.Output;comm.Parameters.Add(f_name); comm.Parameters.Add("@user_id_str", SqlDbType.VarChar, 36).Value = Membership.GetUser().ProviderUserKey.ToString().ToUpper();reader = comm.ExecuteReader();Response.Write("Num: " + reader["@f_name"].ToString()); // ERROR: Invalid attempt to read when no data is present. reader.Close();conn.Close(); The data is there. When I put a watch on 'Reader', I see the correct first_name data there. Your help is appreciated.
Hi i have the following stored procedure which should retrieve data, the problem is that when the user enters a name into the textbox and chooses an option from the dropdownlist it brings back duplicate data and data which should be appearing because the user has entered the exact name they are looking for into the textbox. For instance Pmillio Jones Pmillio Jones Pmillio Jones Robert Walsh Here is my stored procedure; ALTER PROCEDURE [dbo].[stream_UserFind] -- Add the parameters for the stored procedure here @userName varchar(100), @subCategoryID INT,@regionID INT AS SELECT DISTINCT SubCategories.subCategoryID, SubCategories.subCategoryName, Users.userName ,UserSubCategories.userIDFROM Users INNER JOIN UserSubCategoriesON Users.userID= UserSubCategories.userIDINNER JOIN SubCategories ON UserSubCategories.subCategoryID = SubCategories.subCategoryID WHEREuserName LIKE COALESCE(@userName, userName) OR SubCategories.subCategoryID = COALESCE(@subCategoryID,SubCategories.subCategoryID);
Is there a way to retrieve the parameter list for a given stored procedure?
I am trying to create a program that will autogenerate a list of stored procedures and their parameters so that changes to the database can be accurately reflected in code.
We have a domain where all computers are on GMT(Greenwitch Mean Time). We have an access front end that timestamps certain fields according to the client time that the program is running on, but we will be moving our client workstations off of GMT time and keep our SQL Server on GMT time, and want to keep the timestamps GMT.
So, I wanted to know if it was possible to create a stored procedure that gets the Server's time and returns it to the Access frontend for entry into the timestamp fields?
Or, if anyone has a better idea of how to get the time from the server to use on the clients, I would greatly appreciate it!!!
Hello!I use a procedure to insert a new row into a table with an identitycolumn. The procedure has an output parameter which gives me theinserted identity value. This worked well for a long time. Now theidentity value is over 700.000 and I get errors whiles retrieving theinserted identitiy value. If I delete rows and reset the identityeverything works well again. So I think it is a data type problem.My Procedure:create procedure InsertProduct@NEWID int outputasbeginset nocount oninsert into PRODUCT(D_CREATED)values(getdate()+'')set nocount offselect @NEWID = @@IDENTITYendMy C# code:SqlCommand comm = new SqlCommand("InsertProduct", sqlCon);comm.CommandType = CommandType.StoredProcedure;comm.Parameters.Add(new SqlParameter("@NEWID",System.Data.SqlDbType.Int)).Direction =System.Data.ParameterDirection.Output;try{SqlDataReader sqlRead = comm.ExecuteReader();object o = comm.Parameters["@NEWID"].Value;//...}catch ( Exception ex ){throw ex;}The object o is alwaya System.DbNull. I also tried to use bigint.Any hints are welcomeCiaoSusanne
I have parameters in my report. The user can choose the year, month and date (3 parameters). Now I want to set default vaules for the parameters , so that the user sees the report for example for the current day without selecting the parameters. I tried to set the type of the parameters to DateTime and the default value for example for the year to "=Today().Year" . But when I execute the report an error occures . Something like : no validValue for this parameter.
My Attributes for the year month and date are from an Analyis Services Cube from a Server Time dimension . Does somebody know how to make it possible to set default values for this parameters?
Other question :
Does somebody know how I can reduce the values for a parameter. For Example I have a parameter "year" from a server time dimension from a cube. The values which are available are "Year 2004", "Year 2005", "Year 2006", "Year 2007". But I want that the user only can choose "Year 2006" or "Year 2007" ant not every Year or "All". Or Other Example: The User should only choose a Date that is int the past or Today but not a Date in the future.
Hi, I wanted to use a default for yearly instead of monthly for stored procedure, but couldn't figure out how. I usually used stored procedure @start and @end for date. i.e. this is monthly by default @start = jul 2007 and @end= aug 2007; i.e. i want yearly by default @start = jul 2007 and @end= jul 2008.
Hello, I am hoping there is a solution within SQL that work for this instead of making round trips from the front end. I have a stored procedure that is called from the front-end(USP_DistinctBalancePoolByCompanyCurrency) that accepts two parameters and returns one column of data possibly several rows. I have a second stored procedure(USP_BalanceDateByAccountPool) that accepts the previous stored procedures return values. What I would like to do is call the first stored procedure from the front end and return the results from the second stored procedure. Since it's likely I will have more than row of data, can I loop the second passing each value returned from the first? The Stored Procs are: CREATE PROCEDURE USP_DistinctBalancePoolByCompanyCurrency @CID int, @CY char(3) AS SELECT Distinct S.BalancePoolName FROM SiteRef S INNER JOIN Account A ON A.PoolId=S.ID Inner JOIN AccountBalance AB ON A.Id = AB.AccountId Inner JOIN AccountPool AP On AP.Id=A.PoolId Where A.CompanyId=@CID And AB.Currency=@CY
CREATE PROCEDURE USP_BalanceDateByAccountPool @PoolName varchar(50) AS Declare @DT datetime Select @DT= (Select MAX(AccountBalance.DateX) From Company Company INNER JOIN Account Account ON Company.Id = Account.CompanyId INNER JOIN SiteRef SiteRef ON Account.PoolId = SiteRef.ID Inner JOIN AccountBalance AccountBalance ON Account.Id = AccountBalance.AccountId WHERE SiteRef.BalancePoolName = @PoolName) SELECT SiteRef.BalancePoolName, AccountBalance.DateX, AccountBalance.Balance FROM Company Company INNER JOIN Account Account ON Company.Id = Account.CompanyId INNER JOIN SiteRef SiteRef ON Account.PoolId = SiteRef.ID Inner JOIN AccountBalance AccountBalance ON Account.Id = AccountBalance.AccountId WHERE SiteRef.BalancePoolName = @PoolName And AccountBalance.DateX = @DT Order By AccountBalance.DateX DESC
Any assistance would be greatly appreciated. Thank you, Dave
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?
Is there a way inside a stored procedure to determine if a parameter defined with a default value was explicity passed the same value as the default vs. the parameter was omitted and you just got the default value.
E.g. create procedure mysp_stuff @parm1 varchar(20)=NULL, @parm1 bit=0 as if (@parm1 is null) begin -- did we get the default or did the caller pass NULL end if (@parm2 = 0 begin -- did we get the default or did the caller pass 0 end GO
EXEC mysp_stuff go EXEC mysp_stuff @parm1=NULL, @parm2=0 go

Hi everyone, I have created a stored procedure in sql server with parameters for my c# application.

Hi,I have a problem with a call to stored procedure on SQL server. I created stored procedure for inserting a row to a table.In my application I read data from ASP.NET form and prepare parameters for calling my stored procedure. Like: SqlCommand sc = new SqlCommand("AddToMyTable"); try { sc.CommandType = CommandType.StoredProcedure; sc.Connection = new SqlConnection("myconnectionstringhere"); SqlParameter param; param = sc.Parameters.Add("@MyFirstParam", SqlDbType.NVarChar,50); param.Value = "something"; ..... here I repeate "add" and value assignment for all my parameters }...When I call ExecuteNonQuery(); I get exception that one of the parameters for stored procedure is expected but not supplied. However, I can find this very same parameter in my source code to be added to list of parameters. I think my problem is caused by large number of parameters. I have 55 parameters, half of them are of type nvarchar(50) and half of them of type bit. My reasoning is based on the fact that if I remove parameter that is reported to be missing from my stored procedure and from my application, I get the same error with next parameter in the list.Where should I increase maximum number of parameters that are allowed? Do I have some buffer problem? Where to specify that I need more space for parameters? Nenad
There is a form in my project which users can add their emails through it. The maximum numbers of emails are 60. I put a textbox and a button for adding email. But I don’t know which of the following solutions is suitable: 1. After each click by user , the insert stored procedure will be called 2. All the emails entered by users will be saved and then, the insert stored procedure will be called. This SP must have a loop but I am not sure about the right code for this SP because I have to define 60 input parameters for this SP.
