ScriptingOptions sql smo不支持脚本数据

sql

我正在使用C#代码生成sql数据库脚本。

以下代码可以正常工作,create table但是当我尝试使用scriptOptions.ScriptData = true;它时,将引发以下异常。

Microsoft.SqlServer.Smo.dll中发生了类型为“
Microsoft.SqlServer.Management.Smo.FailedOperationException”的未处理异常

附加信息:此方法不支持脚本数据。

代码

 public static string ScriptDatabase(string dbConnectionString, string databaseName)
        {

            SqlConnection conn = new SqlConnection(dbConnectionString);
            ServerConnection serverConn = new ServerConnection(conn);
            var server = new Server(serverConn);
            var database = server.Databases[databaseName];

            var scripter = new Scripter(server);
           // I tried this code also       
           // scripter.Options.ScriptData = true;
            ScriptingOptions scriptOptions = new ScriptingOptions();
            scriptOptions.ScriptDrops = false;
            scriptOptions.ScriptData = true;
            scriptOptions.ScriptSchema = true;


            scriptOptions.IncludeIfNotExists = true;
            string scrs = "";
            string tbScr = "";
            foreach (Table myTable in database.Tables)
            {
                /* Generating IF EXISTS and DROP command for tables */
                StringCollection tableScripts = myTable.Script(scriptOptions);
                foreach (string script in tableScripts)
                    scrs += script + "\n\n";

                /* Generating CREATE TABLE command */
                tableScripts = myTable.Script();
                foreach (string script in tableScripts)
                    tbScr += script + "\n\n";
            }
 return (scrs + "\n\n" + tbScr);
}

对以下内容进行了测试:

  • Win 7.0,.NET 4.0,VS 2010,SQL Server 2008R2
  • Win 7.0,.NET 4.6.1,VS 2017,SQL Server 2014

所需的程序集引用:

  • Microsoft.SqlServer.ConnectionInfo
  • Microsoft.SqlServer.Management.Sdk.Sfc
  • Microsoft.SqlServer.Smo

我使用“确定”按钮创建了一个简单的Win Forms应用程序,并调用了以下功能。

注意:如果要脚本化视图,则需要添加

if( myView.IsSystemObject == true ) continue;

确保未编写系统视图的脚本;我还没有测试。对于旧版本的SQL Server,您可能还需要检查表。

public static string ScriptDatabase( string dbConnectionString, string databaseName )
{
    SqlConnection conn = new SqlConnection( dbConnectionString );
    ServerConnection serverConn = new ServerConnection( conn );
    var server = new Server( serverConn );
    var database = server.Databases[ databaseName ];

    var scripter = new Scripter( server );
    scripter.Options.IncludeIfNotExists = true;
    scripter.Options.ScriptSchema = true;
    scripter.Options.ScriptData = true;

    string scrs = "";
    foreach( Table myTable in database.Tables )
    {
        foreach( string s in scripter.EnumScript( new Urn[] { myTable.Urn } ) )
            scrs += s + "\n\n"; ;
    }
    return ( scrs );
}

函数将如下调用:

// Connection string for local SQL Server default instance
ScriptDatabase( "Server=.;Database=PlayGround;Trusted_Connection=True;", "PlayGround" );

输出:

SET ANSI_NULLS ON

SET QUOTED_IDENTIFIER ON

IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[tBlah]') AND type in (N'U'))
BEGIN
CREATE TABLE [dbo].[tBlah](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [tID] [varchar](20) COLLATE Latin1_General_CI_AS NULL,
    [Value] [varchar](20) COLLATE Latin1_General_CI_AS NULL
) ON [PRIMARY]
END

SET IDENTITY_INSERT [dbo].[tBlah] ON


INSERT [dbo].[tBlah] ([ID], [tID], [Value]) VALUES (1, N'2', N'1234')

INSERT [dbo].[tBlah] ([ID], [tID], [Value]) VALUES (2, N'2', N'345.6')

MSDN参考:

2019年12月17日更新: 检查最新的.NET版本; 添加了必需的参考;清理示例代码;添加了示例conn字符串
