Examples

The following example assumes that the data source has a table named MoneyTable and a stored procedure named MoneyProcedure, which are defined as follows:

CREATE TABLE MoneyTable (col1 int, col2 smallmoney, col3 decimal);

CREATE PROC MoneyProcedure (@p1 int, @p2 smallmoney, @p3 decimal)
AS
INSERT INTO MyTable VALUES (@p1, @p2, @p3);

The example creates parameters and calls the MoneyProcedure stored procedure.

public void CreateMyProc(OdbcConnection connection)
{
    OdbcCommand command = connection.CreateCommand();
    command.CommandText = "{ call MyProc(?,?,?) }";

    OdbcParameter param = new OdbcParameter();
    param.DbType = DbType.Int32;
    param.Value = 1;
    command.Parameters.Add(param);

    param = new OdbcParameter();
    param.DbType = DbType.Decimal;
    param.Value = 1;
    command.Parameters.Add(param);

    param = new OdbcParameter();
    param.DbType = DbType.Decimal;
    param.Value = 1;
    command.Parameters.Add(param);

    command.ExecuteNonQuery();
 }

Public Sub CreateMyProc(ByVal connection As OdbcConnection)

  Dim command As OdbcCommand = connection.CreateCommand()
  Command.CommandText = "{ call MyProc(?,?,?) }"

  Dim param As New OdbcParameter()
  param.DbType = DbType.Int32
  param.Value = 1
  command.Parameters.Add(param)

  param = New OdbcParameter()
  param.DbType = DbType.Decimal
  param.Value = 1
  command.Parameters.Add(param)

  param = New OdbcParameter()
  param.DbType = DbType.Decimal
  param.Value = 1
  command.Parameters.Add(param)

  command.ExecuteNonQuery()

End Sub

Remarks

The number of parameters in the collection must equal the number of parameter placeholders within the command text, or else the .NET Framework Data Provider for ODBC raises an error.
