Delete.cs

using System;

using NUnit.Framework;

using BLToolkit.Data; using BLToolkit.DataAccess;

namespace HowTo.DataAccess { [TestFixture] public class Delete { private int Insert() { using (DbManager db = new DbManager()) { return db .SetCommand(@" INSERT INTO Person ( FirstName, LastName, Gender ) VALUES ( @FirstName, @LastName, @Gender ) SELECT Cast(SCOPE_IDENTITY() as int)", db.Parameter("@FirstName", "Crazy"), db.Parameter("@LastName", "Frog"), db.Parameter("@Gender", "U")) .ExecuteScalar<int>(); } }

[Test] public void Test1() { int id = Insert();

SprocQuery<Person> query = new SprocQuery<Person>();

query.DeleteByKey(id); }

[Test] public void Test3() { int id = Insert();

using (DbManager db = new DbManager()) { SqlQuery<Person> query = new SqlQuery<Person>();

Person person = query.SelectByKey(db, id);

query.Delete(db, person); } } } }

Both DataAccessor.DeleteByKey and DataAccessor.Delete methods generate and execute the following SQL statement:

exec Person_Delete @PersonID=2

Gender.cs

using System;

using BLToolkit.Mapping;

namespace HowTo.DataAccess { public enum Gender { [MapValue("F")] Female, [MapValue("M")] Male, [MapValue("U")] Unknown, [MapValue("O")] Other } }
