我發現自己有一點難題,並希望有人在這裏可以提供幫助。MigratorDotNet需要更改數據庫,但不能使用
我繼承了一箇舊項目,它使用MigratorDotNet部署數據庫。在測試項目的部署(我們現在使用Octopus作爲部署系統)時,我開始出現錯誤,指出代理未啓用,導致應用程序失敗。我創建了一個遷移來啓用數據庫上的代理,但是我爲它創建的遷移返回一個錯誤,指出「在多語句事務中不允許使用ALTER DATABASE語句」。
這裏的遷移:

[Migration(201608121015)]
public class EnableSqlServiceBroker : Migration
{
public override void Down()
{
var assemblyRoot = System.Reflection.Assembly.GetExecutingAssembly().Location;
var webConfigFileLocation = Path.Combine(assemblyRoot.Substring(0, assemblyRoot.IndexOf("\\bin")), "Web.config");
var configuration = ConfigurationManager.OpenMappedExeConfiguration(new ExeConfigurationFileMap { ExeConfigFilename = webConfigFileLocation }, ConfigurationUserLevel.None);
var appSettings = (configuration.GetSection("appSettings") as AppSettingsSection);
var databaseName = appSettings.Settings[Constants.DatabaseName].Value;
var stringBuilder = new StringBuilder()
// Declare the BrokerEnabled variable and set it
.AppendLine("DECLARE @BrokerEnabled bit")
.AppendLine("SET @BrokerEnabled = 0")
.AppendLine(
string.Format("SELECT @BrokerEnabled = is_broker_enabled FROM sys.databases WHERE name = '{0}'",
databaseName))
.AppendLine("IF(@BrokerEnabled = 1)")
.AppendLine("BEGIN")
// disable the broker
.AppendLine(string.Format(" ALTER DATABASE [{0}] SET DISABLE_BROKER", databaseName))
.AppendLine("END");
Database.ExecuteNonQuery(stringBuilder.ToString());
}
public override void Up()
{
var assemblyRoot = System.Reflection.Assembly.GetExecutingAssembly().Location;
var webConfigFileLocation = Path.Combine(assemblyRoot.Substring(0, assemblyRoot.IndexOf("\\bin")), "Web.config");
var configuration = ConfigurationManager.OpenMappedExeConfiguration(new ExeConfigurationFileMap { ExeConfigFilename = webConfigFileLocation }, ConfigurationUserLevel.None);
var appSettings = (configuration.GetSection("appSettings") as AppSettingsSection);
var databaseName = appSettings.Settings[Constants.DatabaseName].Value;
var stringBuilder = new StringBuilder()
// Declare the BrokerEnabled variable and set it
.AppendLine("DECLARE @BrokerEnabled bit")
.AppendLine("SET @BrokerEnabled = 0")
.AppendLine(string.Format("SELECT @BrokerEnabled = is_broker_enabled FROM sys.databases WHERE name = '{0}'", databaseName))
.AppendLine("IF(@BrokerEnabled = 0)")
.AppendLine("BEGIN")
// enable the broker
.AppendLine(string.Format(" ALTER DATABASE [{0}] SET ENABLE_BROKER", databaseName))
.AppendLine("END");
Database.ExecuteNonQuery(stringBuilder.ToString());
}
}
我不能沒有改變數據庫啓用經紀人,但我不能改變數據庫,因爲這顯然是不允許的。有沒有人知道解決這個問題的方法?或者修復它?提前致謝。
我不認爲ALTER DATABASE適合遷移。就像開始創建數據庫一樣,DBA應該以交互方式自行完成。 –
