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。
create table
scriptOptions.ScriptData = true;
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:
所需的程序集引用:
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')
