Il existe plusieurs façons d'y parvenir en fonction de certaines spécificités de votre projet. Nous avons des fichiers .sql qui, lorsqu'ils sont exécutés, recréent la base de données. Cela permet aux scripts d'entrer dans votre contrôle source et d'être versionnés comme tout le reste. Il permet également d'ajouter des scripts de modification une fois qu'un produit est en production.
Nous l'utiliser pour déposer tous les objets dans notre base de données:
private static void DropDatabaseObjects()
{
var dropDatabaseObjects =
@"
/* Drop all non-system stored procs */
DECLARE @name VARCHAR(128)
DECLARE @constraint VARCHAR(254)
DECLARE @SQL VARCHAR(254)
SELECT @name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] = 'P' AND category = 0 ORDER BY [name])
WHILE @name is not null
BEGIN
SELECT @SQL = 'DROP PROCEDURE [dbo].[' + RTRIM(@name) +']'
EXEC (@SQL)
PRINT 'Dropped Procedure: ' + @name
SELECT @name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] = 'P' AND category = 0 AND [name] > @name ORDER BY [name])
END
/* Drop all views */
SELECT @name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] = 'V' AND category = 0 ORDER BY [name])
WHILE @name IS NOT NULL
BEGIN
SELECT @SQL = 'DROP VIEW [dbo].[' + RTRIM(@name) +']'
EXEC (@SQL)
PRINT 'Dropped View: ' + @name
SELECT @name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] = 'V' AND category = 0 AND [name] > @name ORDER BY [name])
END
/* Drop all functions */
SELECT @name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] IN (N'FN', N'IF', N'TF', N'FS', N'FT') AND category = 0 ORDER BY [name])
WHILE @name IS NOT NULL
BEGIN
SELECT @SQL = 'DROP FUNCTION [dbo].[' + RTRIM(@name) +']'
EXEC (@SQL)
PRINT 'Dropped Function: ' + @name
SELECT @name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] IN (N'FN', N'IF', N'TF', N'FS', N'FT') AND category = 0 AND [name] > @name ORDER BY [name])
END
/* Drop all Foreign Key constraints */
SELECT @name = (SELECT TOP 1 TABLE_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE constraint_catalog=DB_NAME() AND CONSTRAINT_TYPE = 'FOREIGN KEY' ORDER BY TABLE_NAME)
WHILE @name is not null
BEGIN
SELECT @constraint = (SELECT TOP 1 CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE constraint_catalog=DB_NAME() AND CONSTRAINT_TYPE = 'FOREIGN KEY' AND TABLE_NAME = @name ORDER BY CONSTRAINT_NAME)
WHILE @constraint IS NOT NULL
BEGIN
SELECT @SQL = 'ALTER TABLE [dbo].[' + RTRIM(@name) +'] DROP CONSTRAINT ' + RTRIM(@constraint)
EXEC (@SQL)
PRINT 'Dropped FK Constraint: ' + @constraint + ' on ' + @name
SELECT @constraint = (SELECT TOP 1 CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE constraint_catalog=DB_NAME() AND CONSTRAINT_TYPE = 'FOREIGN KEY' AND CONSTRAINT_NAME <> @constraint AND TABLE_NAME = @name ORDER BY CONSTRAINT_NAME)
END
SELECT @name = (SELECT TOP 1 TABLE_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE constraint_catalog=DB_NAME() AND CONSTRAINT_TYPE = 'FOREIGN KEY' ORDER BY TABLE_NAME)
END
/* Drop all Primary Key constraints */
SELECT @name = (SELECT TOP 1 TABLE_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE constraint_catalog=DB_NAME() AND CONSTRAINT_TYPE = 'PRIMARY KEY' ORDER BY TABLE_NAME)
WHILE @name IS NOT NULL
BEGIN
SELECT @constraint = (SELECT TOP 1 CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE constraint_catalog=DB_NAME() AND CONSTRAINT_TYPE = 'PRIMARY KEY' AND TABLE_NAME = @name ORDER BY CONSTRAINT_NAME)
WHILE @constraint is not null
BEGIN
SELECT @SQL = 'ALTER TABLE [dbo].[' + RTRIM(@name) +'] DROP CONSTRAINT ' + RTRIM(@constraint)
EXEC (@SQL)
PRINT 'Dropped PK Constraint: ' + @constraint + ' on ' + @name
SELECT @constraint = (SELECT TOP 1 CONSTRAINT_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE constraint_catalog=DB_NAME() AND CONSTRAINT_TYPE = 'PRIMARY KEY' AND CONSTRAINT_NAME <> @constraint AND TABLE_NAME = @name ORDER BY CONSTRAINT_NAME)
END
SELECT @name = (SELECT TOP 1 TABLE_NAME FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE constraint_catalog=DB_NAME() AND CONSTRAINT_TYPE = 'PRIMARY KEY' ORDER BY TABLE_NAME)
END
/* Drop all tables */
SELECT @name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] = 'U' AND category = 0 ORDER BY [name])
WHILE @name IS NOT NULL
BEGIN
SELECT @SQL = 'DROP TABLE [dbo].[' + RTRIM(@name) +']'
EXEC (@SQL)
PRINT 'Dropped Table: ' + @name
SELECT @name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] = 'U' AND category = 0 AND [name] > @name ORDER BY [name])
END";
using (var connection = new SqlConnection(GetConnectionStringFromHibernateConfiguration("hibernate.cfg.xml")))
using (var command = new SqlCommand(dropDatabaseObjects, connection))
{
connection.Open();
command.ExecuteNonQuery();
connection.Close();
}
}
Nous utilisons ce pour recréer notre base de données (en supposant que le dbScriptFolder contient des fichiers .sql qui permettra de créer toutes les tables, vues, procédures stockées, etc):
private static void RecreateDatabase()
{
var directoryInfo = new DirectoryInfo(ConfigurationManager.AppSettings["dbScriptFolder"]);
using (var connection = new SqlConnection(GetConnectionStringFromHibernateConfiguration("hibernate.cfg.xml")))
{
connection.Open();
foreach (var fileInfo in directoryInfo.GetFiles())
{
if (fileInfo.Extension == ".sql")
{
var script = ReadFromFile(fileInfo);
var server = new Server(new ServerConnection(connection));
server.ConnectionContext.ExecuteNonQuery(script);
}
}
connection.Close();
}
}
Ces méthodes s'appellent dans une méthode de TestFixture de base lorsque nous gérons nos tests d'intégration afin que nous savons que nous travaillons avec notre base de données dans un état connu.

Je marque ceci comme la réponse car c'est fondamentalement comment je l'ai fait. ce blog que j'ai trouvé était très pratique aussi: http://blog.reamped.net/post/2008/05/Using-Database-Projects-for-Visual-Studio.aspx –
