ScriptingOptions sql smo不支持脚本数据 [英] ScriptingOptions sql smo does not support scripting data

问题描述

我正在使用c＃代码生成sql数据库脚本。

I'm generating sql database script using c# code.

以下代码对于 create table 正常工作，但是当我尝试使用 scriptOptions.ScriptData = true; 时，它将引发以下异常。

following code works fine for create table but when I try to use scriptOptions.ScriptData = true; it is throwing following exception.

Microsoft.SqlServer.Smo.dll中的
发生了类型为
'Microsoft.SqlServer.Management.Smo.FailedOperationException'的未处理异常

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

附加信息：此方法不支持脚本数据。

Additional information: This method does not support scripting data.

code

 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);
}

推荐答案

对以下内容进行了测试：

The following was tested on:

• 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

我创建了一个简单的Win窗体应用程序，单击确定按钮并调用了以下功能。

I created a simple Win forms app with OK button and called below function.

注意：如果要脚本化视图，则需要添加

Note: If scripting out views you need to add

if( myView.IsSystemObject == true ) continue;

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

to ensure that system views are not being scripted; I have not tested this. For old versions of SQL Server you may also need this check for tables as well.

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 );
}

该函数的调用方式如下：

Function would be called as follows:

// 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：

• Microsoft.SqlServer.Management.Smo.Scripter


• Microsoft.SqlServer.Management.Common.ServerConnection


• Microsoft.SqlServer.Management.Smo.Server


• Microsoft.SqlServer.Management.Smo.Database

• Microsoft.SqlServer.Management.Smo.Scripter
• Microsoft.SqlServer.Management.Common.ServerConnection
• Microsoft.SqlServer.Management.Smo.Server
• Microsoft.SqlServer.Management.Smo.Database

更新至2019年12月17日：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

Updated 17-Dec-2019: Check with latest .NET version; Added required References; Clean-up example code; Added sample conn string
