Syntax Error using objCommand.Parameters.Add......attempting to write data to sql database

I am trying to write a record to  an SQL database.  I thought I have correctly delcared my variables but the system is giving a syntax error on the admDate line.  It is telling me to define the variable, but I have already defined it.  The admDate is actually Dim as a String variable....Would this create my problem?????

Any help is greatly appreciated.


Dim admDate As String

Try
                'Write ELA Objective Info record
                Dim objConnection As SqlConnection = New SqlConnection("server=(local);database=FBISD-TAKS;user id=sa;password=pa55word")
                Dim objCommand As SqlCommand = New SqlCommand
                objCommand.Connection = objConnection

                Dim r4 As Int32
                For r4 = 1 To 51
                    objCommand.CommandText = "Insert Into itemAnalysisDetail " & "(admDate, studentId, teacherId, objectiveNumber, itemCorrectResp, studentResp) " & _
                                "VALUES(@admDate,@studentId,@teacherId,@readingElaobj(r4),@readingElaItemCorrectRespArray(r4),@readingElaStudentRespArray(r4))"
                    objCommand.Parameters.Add("@admDate", SqlDbType.DateTime, 10)    <<<------- Problem Line..I Think!
                    objCommand.Parameters.Add("@studentId", SqlDbType.Int, 4)
                    objCommand.Parameters.Add("@teacherId", SqlDbType.Int, 4)
                    objCommand.Parameters.Add("@readingElaobj", SqlDbType.VarChar, 2)
                    objCommand.Parameters.Add("@readingElaItemCorrectRespArray", SqlDbType.Int, 4)
                    objCommand.Parameters.Add("@readingElaStudentRespArray", SqlDbType.Int, 4)
                    objConnection.Open()
                    objCommand.ExecuteNonQuery()
                    objConnection.Close()
                Next
            Catch ex As Exception
                MsgBox(ex.Message)

            End Try

Thanks
Kenny

Hi Kenny,

Are you trying to hit a stored procedure? or just trying to run that insert as is?

the problem is ...

"VALUES(@admDate,@studentId,@teacherId,@readingElaobj(r4),@readingElaItemCorrectRespArray(r4),@readingElaStudentRespArray(r4))"

the (r4)s are you trying to access an array there ?

Hey Kenny,

  Gregory has a point on those lines.  The values you want are the parameter names that you are adding, so you would want to assighn the values when you create the parameters.

  So Instead of This:

     "VALUES(@admDate,@studentId,@teacherId,@readingElaobj(r4),@readingElaItemCorrectRespArray(r4),@readingElaStudentRespArray(r4))"

   You'll want

      "VALUES @admDate,@studentId,@teacherId,@readingElaobj,@readingElaItemCorrectRespArray,@readingElaStudentRespArray)"

  Then when you create your parameters you'll need to go

objCommand.Parameters.Add("@admDate", SqlDbType.DateTime, 10).value = [VariableName]

  if it is in an array you'll need

objCommand.Parameters.Add("@admDate", SqlDbType.DateTime, 10).value = [variableName].(index)

I thought I was setting the values to the memory variables I had set previously in the program.  Does it not work this way??

Thanks

Thank you both for turning on so many lights.  I have been trying to understand the syntax and how this works for about 3 to 4 days now.  All the tutorials and Wrox books I have read never really made this clear.  Let me go make so major changes to my code.   Again   THANKS FOR YOUR HELP


Thanks
