Good day all!!! I'm new to this forum. So please forgive me if I have posted in the wrong forum.
I'm create a CLR Stored Procedure using VS 2010, VB.Net using MS.SQL Server 2008. See code below
Partial Public Class StoredProcedures
<Microsoft.SqlServer.Server.SqlProcedure()> _
Public Shared Sub user_login1(ByVal User_UserName As SqlString, ByVal User_Password As SqlString, ByRef Station As SqlString, <Out()> ByVal Users_RowID As SqlInt32, <Out()> ByVal Users_Name As SqlString, <Out()> ByVal Success As SqlBoolean, <Out()> ByVal Default_Message As SqlString)
Using conn As New SqlConnection("context connection=true")
Dim LoginCommand As New SqlCommand()
Dim sqlparam(6) As SqlParameter
sqlparam(0) = New SqlParameter("@User_UserName", SqlDbType.VarChar, 50)
sqlparam(1) = New SqlParameter("@User_Password", SqlDbType.VarChar, 50)
sqlparam(2) = New SqlParameter("@Station", SqlDbType.VarChar)
sqlparam(3) = New SqlParameter("@Users_RowID", SqlDbType.Int, 100, ParameterDirection.Output, False, 0, 0, String.Empty, DataRowVersion.Default, 0)
sqlparam(4) = New SqlParameter("@Users_Name", SqlDbType.VarChar, 100, ParameterDirection.Output, False, 0, 0, String.Empty, DataRowVersion.Default, String.Empty)

LoginCommand.Connection = conn
conn.Open()
LoginCommand.ExecuteNonQuery()
conn.Close()
End Using
End Sub
End Class
When I try to run it I keep getting the same error:
Deploy error SQL01268: .Net SqlClient Data Provider: Msg 6580, Level 16, State 1, Procedure user_login1, Line 1 Declarations do not match for parameter 4. .NET Framework reference and T-SQL OUTPUT parameter declarations must match.
Deploy error SQL01268: .Net SqlClient Data Provider: Msg 6552, Level 16, State 3, Procedure user_login1, Line 1 CREATE PROCEDURE for "user_login1" failed because T-SQL and CLR types for parameter "@Users_RowID" do not match.
I have tried changing the type to: Int32, Integer, SqlInt32, SqlInteger, and so on and so on; with no luck...
Please help
Thanx in advance...

I'm not certain about VB but in C# the parameters are passed in by reference. Also, for SqlString you have to refer to them as follows:

sqlparam(0).Value = User_UserName.Value; // the value of the SqlString

sqlparam(1).Value = User_Password.Value;

sqlparam(2).Value = Station.Value; // the value of the SqlString

sqlparam(3).Value = Users_RowID

sqlparam(4).Value = Users_Name.Value; // the value of the SqlString

sqlparam(5).Value = Success

sqlparam(6).Value = Default_Message.Value; // the value of the SqlString

This is what I have now, but it's still giving me the same error message:

.Value is nice to put there too, but the important place to put it is at the end of the SqlString variables you're passing in.

not

sqlparam(0).Value = User_UserName

sqlparam(1).Value = User_Password

but

sqlparam(0).Value = User_UserName.Value

sqlparam(1).Value = User_Password.Value

Hi!!!

Thanx for the reply...

I have tried that but still getting the same error. The error type mismatch occurs with the parameter @Users_RowID:

"CREATE PROCEDURE for "user_login1" failed because T-SQL and CLR types for parameter "@Users_RowID" do not match."

Public Shared Sub user_login1(ByVal User_UserName As SqlString, ByVal User_Password As SqlString, ByRef Station As SqlString, <Out()> ByVal Users_RowID As SqlInt32, <Out()> ByVal Users_Name As SqlString, <Out()> ByVal Success As SqlBoolean, <Out()> ByVal Default_Message As SqlString)

...

sqlparam(0) = New SqlParameter("@User_UserName", SqlDbType.VarChar, 50)

sqlparam(1) = New SqlParameter("@User_Password", SqlDbType.VarChar, 50)

sqlparam(2) = New SqlParameter("@Station", SqlDbType.VarChar)

sqlparam(3) = New SqlParameter("@Users_RowID", SqlDbType.Int, 100, ParameterDirection.Output, False, 0, 0, String.Empty, DataRowVersion.Default, 0)

sqlparam(4) = New SqlParameter("@Users_Name", SqlDbType.VarChar, 100, ParameterDirection.Output, False, 0, 0, String.Empty, DataRowVersion.Default, String.Empty)

sqlparam(5) = New SqlParameter("@Success", SqlDbType.Bit, 1, ParameterDirection.Output, False, 0, 0, String.Empty, DataRowVersion.Default, 0)

sqlparam(6) = New SqlParameter("@Default_Message", SqlDbType.VarChar, 200, ParameterDirection.Output, False, 0, 0, String.Empty, DataRowVersion.Default, String.Empty)

sqlparam(0).Value = User_UserName.Value

sqlparam(1).Value = User_Password.Value

sqlparam(2).Value = Station.Value

sqlparam(3).Value = Users_RowID

sqlparam(4).Value = Users_Name.Value

sqlparam(5).Value = Success

sqlparam(6).Value = Default_Message.Value

...

LoginCommand.Connection = conn

conn.Open()

LoginCommand.ExecuteNonQuery()

Users_RowID = Convert.ToInt32(sqlparam(3).Value)

Users_Name = Convert.ToString(sqlparam(4).Value)

Success = Convert.ToBoolean(sqlparam(5).Value)

Default_Message = Convert.ToString(sqlparam(6).Value)

conn.Close()
