    SqlParameter Class
    In This Topic
    Represents a parameter to a SqlCommand, and optionally, its mapping to System.Data.DataSet columns.
    Syntax
    Remarks

    Parameter names are not case-sensitive.

    Refer to article Using Parameters in dotConnect for SQL Server to obtain detailed information on the matter together with some advanced examples.

    When executing stored procedures you have to create SqlParameter with Devart.Common.DbParameter.Direction set to ReturnValue or set ParameterCheck property to true.

    Example
    The following example creates multiple instances of SqlParameter through the SqlParameterCollection within the SqlDataAdapter. These parameters are used to select data from SQL Server and place the data in the System.Data.DataSet. This example assumes that a System.Data.DataSet and a SqlDataAdapter have already been created with the appropriate schema, commands, and connection.
    public void AddSqlParameters()
    {
      // ...
      // create myDataSet and myDataAdapter
      // ...
      myDataAdapter.SelectCommand.Parameters.Add("DName", SqlType.VarChar, 15).Value = "DEVELOPMENT";
      myDataAdapter.SelectCommand.Parameters.Add("DeptNo", SqlType.Int).Value = 50;
      myDataAdapter.Fill(myDataSet);
    }
    Public Sub AddSqlParameters()
      ' ...
      ' create myDataSet and myDataAdapter
      ' ...
      myDataAdapter.SelectCommand.Parameters.Add("DName", SqlType.VarChar, 15).Value = "DEVELOPMENT"
      myDataAdapter.SelectCommand.Parameters.Add("DeptNo", SqlType.Int).Value = 50
      myDataAdapter.Fill(myDataSet)
    End Sub
