The SqlQuery and SprocQuery classes can be used to perform simple CRUDL operations such as SelectByKey, SelectAll, Insert, Update, and Delete.
OpenConfigQuery.cs
using System;
using NUnit.Framework;
using BLToolkit.Data;
using BLToolkit.DataAccess;
using BLToolkit.Mapping;
namespace HowTo.DataAccess
{
[TestFixture]
public class OpenConfigQuery
{
public class Person
{
[MapField("PersonID"), PrimaryKey, NonUpdatable]
public int ID;
public string LastName;
public string FirstName;
public string MiddleName;
}
// DbManager is created by SqlQuery.
//
[Test]
public void Test1()
{
SqlQuery<Person> query = new SqlQuery<Person>();
Person person = query.SelectByKey(1);
Assert.IsNotNull(person);
}
// SqlQuery takes DbManager as a parameter.
//
[Test]
public void Test2()
{
using (DbManager db = new DbManager())
{
SqlQuery<Person> query = new SqlQuery<Person>(db);
Person person = query.SelectByKey(1);
Assert.IsNotNull(person);
}
}
// SqlQuery method takes DbManager as a parameter.
//
[Test]
public void Test3()
{
using (DbManager db = new DbManager())
{
SqlQuery<Person> query = new SqlQuery<Person>();
Person person = query.SelectByKey(db, 1);
Assert.IsNotNull(person);
}
}
}
}
