目前使用SqlPackage.exe cmd行工具生成脚本,方法是将DacPac文件与目标数据库进行比较。这将是Create the database if it doesn't already exist。
我们现在想要将其切换为使用Microsoft.Data.Tools.Msbuild Nuget包(使用C#进行部署),但是当数据库容器不存在时,使用SchemaComparison进行比较将失败。似乎没有太多与该软件包相关的文档。
是否有任何工具作为此包的一部分,这将允许我在比较之前创建一个空的数据库容器?
我目前正在使用以下代码(在与现有数据库进行比较时有效):
SchemaCompareDacpacEndpoint sourceDacpac = new SchemaCompareDacpacEndpoint(@"C:\DeployDB.dacpac");
SqlConnectionStringBuilder csb = new SqlConnectionStringBuilder();
csb.DataSource = @".";
csb.InitialCatalog = "DeployTestDB";
csb.IntegratedSecurity = true;
SchemaCompareDatabaseEndpoint targetDatabase = new SchemaCompareDatabaseEndpoint(csb.ToString());
SchemaComparison comparison = new SchemaComparison(sourceDacpac, targetDatabase);
comparison.Options.DropObjectsNotInSource = true;
comparison.Options.BlockOnPossibleDataLoss = false;
comparison.Options.TreatVerificationErrorsAsWarnings = true;
comparison.Options.ScriptDatabaseOptions = true;
comparison.Options.GenerateSmartDefaults = true;
SchemaComparisonResult comparisonResult = comparison.Compare();
此时,ComparisonResult有一条错误消息: {错误SQL0:无法打开数据库" DeployTestDB"登录请求。登录失败。用户' myUsername'。}
登录失败答案 0 :(得分:1)
查看Microsoft.SqlServer.Dac.dll中的DacServices类。
代码看起来像这样:
using Microsoft.SqlServer.Dac;
class Program
{
static void Main(string[] args)
{
DacServices ds = new DacServices(@"Data Source=SERVERNAME;Initial Catalog=DATABASENAME;Integrated Security=true");
using (DacPackage dp = DacPackage.Load(@"C:\temp\mydb.dacpac"))
{
ds.Deploy(dp, @"DATABASENAME", upgradeExisting: false, options: null, cancellationToken: null);
}
}
}
