optional output parameter in CLR Stored Procedure

Posted By:      Posted Date: August 28, 2010    Points: 0   Category :Sql Server
I'm trying to transpose a Procedure that sends mail via CDO.Message and Ole Automation to a .Net CLR Procedure. this procedure must have the same parameters in the same order as the original to maintain compatibility with everything that already uses it. the declaration goes as follow   <Microsoft.SqlServer.Server.SqlProcedure(name:="SP_ENVIAEMAIL")> _<br/> Public Shared Sub ENVIAEMAIL(<SqlFacet(MaxSize:=100)> Optional ByVal De As String = "", <SqlFacet(MaxSize:=100)> Optional ByVal Para As String = "", _<br/> <SqlFacet(MaxSize:=100)> Optional ByVal Copia As String = "", <SqlFacet(MaxSize:=100)> Optional ByVal Oculta As String = "", _<br/> <SqlFacet(MaxSize:=100)> Optional ByVal Assunto As String = "", <SqlFacet(MaxSize:=-1)> Optional ByVal Mensagem As String = "", _<br/> <SqlFacet(MaxSize:=-1)> Optional ByVal Anexo As String = "", _<br/> <strong><SqlFacet(MaxSize:=1000)> <Out()> Optional ByVal Retorno As String = ""</strong> , _<br/> <SqlFacet(MaxSize:=100)> Optional ByVal Smtp As String = "", <SqlFacet(MaxSize:=100)> Optional ByVal Usuario As String = "",

Using IN clause(string parameter) in Stored Procedure

Hi guys. I need to use IN clause in a selection query. From all the resources that I found from google, it's all about adding a function to split a integer parameter into a list. But I got a string parameter, for example 'A1,B1,C1' I tried to use the below where single quotes in @CustCode is double up. ___________________________________ Declare @SQL VarChar(1000)   SELECT @SQL = ' SELECT [something]' SELECT @SQL = @SQL + ' FROM [Table]' SELECT @SQL = @SQL + ' WHERE CustomerCode IN ('  + @CustCode + ')'   EXECUTE (@SQL) _____________ Executing the stored procedure in MSSQL works fine, but it didn't when executing from Visual Studio 2005. Please advice.

Launching a stored procedure with parameter from Excel 2003

Executing an SSIS package from an stored procedure and passing a parameter to it:

Hello all, I'm trying to execute an SSIS package from an stored procedure, using xp_cmdshell. When I execute the package, hard coding the value on the variable, I get rows inserted to my destination tables, which indicates my package pulled the correct data based on the TransactionID parameter. When I execute the package from the stored procedure, the package executes without issues, but I get no rows inserted into my destination tables, which leads me to think it is a data type issue, between the package and the variables I'm using within the stored procedure. The variable TransactionID on the SSIS package, is a string data type, therefore I'm passing it as a varchar from the stored procedure. Am I doing this correctly? Maybe I'm missing something, can you guys see anything wrong? Also, I tried login into the server and executing these 2 commands on the cmd prompt: One with "" quotes between the TransactionID value: dtexec /FILE "D:\SSISPackages\MyOrderCheckProcess\MyOrderCheck_RenewalOrder.dtsx" /CONFIGFILE "D:\SSISPackages\MyOrderCheckProcess\MyOrderCheckProcess_Config.dtsConfig" /CHECKPOINTING OFF  /REPORTING EWCDI  /SET \Package.Variables[User::TransactionID].Properties[Value];"470219"   And also one without quotes between the TransactionID value: dtexec /FILE "D:\SSISPackages\MyOrderCheckProcess\MyOrde

Rounding problem for money output parameter from stored proc

I have a GridView sourced by a SQL Server stored procedure with several databound fields, including a money column for item values. My stored proc returns the data through a SELECT and everything looks good. The stored proc also has a single output parameter that sums the total value of the displayed data, and this value is displayed in a label above the GridView. The output parameter (defined as money on the SQL Server side) is passed back to the app in good shape, but is rounded when displayed in the DataSource_Selected event handler. So a total of $30,155.22 in SQL Server shows up as $30155 on my aspx.In debugging, I have confirmed that the value leaving SQL Server is correct (30155.2200), and I can see that the value coming IN to the ASP-side event handler is already rounded. What do I need to do here to coerce/force it to show as money/currency?Relevant snippets:Stored Proc:... @onHandValue money OUT...  CREATE TABLE #tempValueOnHand(... valueOnHand money )... set @onHandValue = (select round(sum(valueOnHand), 2) from #tempValueOnHand) set @onHandValue = (select sum(valueOnHand) from #tempValueOnHand)And again, the output parameter @onHandValue is coming back, just already rounded.On the ASP side:    Protected Sub SqlDataSource1_Selected(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles SqlDataSourc

Stored Procedure, when to use Output paramemter vs Return variable


When would you use an output parameter vs a return variable, or vice versa? In the following simple example, I can achieve the samething using either one.

Using output parameter

create proc dbo.TestOutput (@InValue int, @OutValue int output)
set @OutValue = @InValue

declare @x int
exec TestOutput @InValue = 3, @OutValue = @x output
select @x


Using return variable:

create proc dbo.TestReturn (@InValue int)
return @InValue

declare @x int
exec @x = TestReturn @InValue = 3
select @x


As you can see, they both do the samething. Can someone show me an example where the choice of a output parameter vs a return variable would make a difference?

Need a string output from stored procedure


hai everyone,,

I got a situation now... i had a stored proc: How can i get the final select statement in the code behind.

Here is the stored proc.

ALTER PROCEDURE [dbo].[tgms_reclass_PO_bip](@po VARCHAR(20), @old_gl VARCHAR(20), @new_gl VARCHAR(20),@output varchar(500) out )

IF (SELECT COUNT(*) FROM mm2po WHERE scode = @po) = 0
    --SET @output = '1'
    SET @output = 'Invalid PO Number'

Check if Old GL Code is valid
IF (@output = '' AND (SELECT COUNT(*) FROM acct WHERE scode = REPLACE(@old_gl,'-','')) = 0)
    --SET @output = '2'
    SET @output = 'Invalid Old GL Account'

Check if New GL Code is valid
IF (@output = '' AND (SELECT COUNT(*) FROM acct WHERE scode = REPLACE(@new_gl,'-','')) = 0)
    --SET @output = '3'
    SET @output = 'Invalid New GL Account'


Datetime filter value pass to BCS stored procedure parameter


I have data coming from one of the stored procedures that has startdate and enddate as parameters.I have created a business data webpart tht accepts this ECT.When I give the start date and end date in this format----> 2010-02-02 00:00:00Z,I can able to get the data from the database.

               As this is not a feasible approach,I have used a two datetime filters that has calendar control attached to it,so that user can use this to pick the start date and end date.Now,my issue here is when I choose the startdate and enddate,ECT is not accepting the format of the date that these filters are passing.I have changed the filter descriptor LOBDateTimeMode to "Local" in the external content type,but still I am receiving the same error.Does any one has any solution for this??
