ScriptingOptions sql smo 不支持脚本数据

Question

我正在使用 C# 代码生成 sql 数据库脚本。

以下代码适用于 create table 但当我尝试使用 scriptOptions.ScriptData = true; 时它抛出以下异常。

An unhandled exception of type 'Microsoft.SqlServer.Management.Smo.FailedOperationException' occurred in Microsoft.SqlServer.Smo.dll

Additional information: This method does not support scripting data.

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);
}

以下是在以下平台上测试的：

Win 7.0、.NET 4.0、VS 2010、SQL服务器 2008R2
Win 7.0、.NET 4.6.1、VS 2017、SQL服务器 2014

所需的程序集引用：

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

我创建了一个带有确定按钮的简单 Win 表单应用程序并调用了以下函数。

注意：如果编写视图脚本，您需要添加

if( myView.IsSystemObject == true ) continue;

确保系统视图不被脚本化；我没有测试过这个。对于旧版本的 SQL 服务器，您可能还需要对表进行此检查。

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 );
}

函数将按如下方式调用：

// 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')
