GO语句在.NET中炸毁sql执行

Question

我有一个非常简单的C#命令shell应用程序,它执行SQL Server生成的sql脚本,用于脚本架构和数据.它正在吹嘘"GO"声明.错误信息:

'GO'附近的语法不正确.

这是完整的sql脚本:

/****** Object:  Table [gym].[MembershipStatus]    Script Date: 9/3/2013 9:24:01 AM ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
SET ANSI_PADDING ON
GO
CREATE TABLE [gym].[MembershipStatus](
    [MembershipStatusID] [tinyint] IDENTITY(1,1) NOT NULL,
    [Name] [varchar](75) NOT NULL,
    [Description] [varchar](400) NOT NULL,
    [AllowCheckin] [bit] NOT NULL,
    [IncludeInCollections] [bit] NOT NULL,
    [ScheduleFutureInvoices] [bit] NOT NULL,
 CONSTRAINT [MembershipStatus_PK] PRIMARY KEY CLUSTERED 
(
    [MembershipStatusID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO
SET ANSI_PADDING OFF
GO
SET IDENTITY_INSERT [gym].[MembershipStatus] ON 

INSERT [gym].[MembershipStatus] ([MembershipStatusID], [Name], [Description], [AllowCheckin], [IncludeInCollections], [ScheduleFutureInvoices]) VALUES (1, N'Active', N'Active', 1, 1, 1)
INSERT [gym].[MembershipStatus] ([MembershipStatusID], [Name], [Description], [AllowCheckin], [IncludeInCollections], [ScheduleFutureInvoices]) VALUES (2, N'Cancelled', N'Cancelled', 0, 1, 0)
INSERT [gym].[MembershipStatus] ([MembershipStatusID], [Name], [Description], [AllowCheckin], [IncludeInCollections], [ScheduleFutureInvoices]) VALUES (3, N'Collection', N'Collection', 0, 0, 0)
INSERT [gym].[MembershipStatus] ([MembershipStatusID], [Name], [Description], [AllowCheckin], [IncludeInCollections], [ScheduleFutureInvoices]) VALUES (4, N'Deleted', N'Deleted', 0, 0, 0)
INSERT [gym].[MembershipStatus] ([MembershipStatusID], [Name], [Description], [AllowCheckin], [IncludeInCollections], [ScheduleFutureInvoices]) VALUES (5, N'Expired', N'Expired', 1, 1, 1)
INSERT [gym].[MembershipStatus] ([MembershipStatusID], [Name], [Description], [AllowCheckin], [IncludeInCollections], [ScheduleFutureInvoices]) VALUES (6, N'Freeze', N'Freeze', 0, 1, 0)
INSERT [gym].[MembershipStatus] ([MembershipStatusID], [Name], [Description], [AllowCheckin], [IncludeInCollections], [ScheduleFutureInvoices]) VALUES (7, N'Inactive', N'Inactive', 0, 1, 1)
SET IDENTITY_INSERT [gym].[MembershipStatus] OFF
ALTER TABLE [gym].[MembershipStatus] ADD  DEFAULT ('') FOR [Name]
GO
ALTER TABLE [gym].[MembershipStatus] ADD  DEFAULT ('') FOR [Description]
GO
ALTER TABLE [gym].[MembershipStatus] ADD  DEFAULT ((0)) FOR [AllowCheckin]
GO
ALTER TABLE [gym].[MembershipStatus] ADD  DEFAULT ((0)) FOR [IncludeInCollections]
GO
ALTER TABLE [gym].[MembershipStatus] ADD  DEFAULT ((0)) FOR [ScheduleFutureInvoices]
GO

我的代码的相关部分如下所示:

SqlCommand command = new SqlCommand(script, connection);
command.CommandType = CommandType.Text;
command.ExecuteNonQuery();

有任何想法吗？

Answer 1

正如其他人提到的,用GO语句分割你的字符串.但要小心,您可能"GO"在脚本的其他部分有文本.您可能在GO语句之前或之后都有空格,并且您可能还会在GO语句之后对该行进行注释.任何这些都在SSMS中有效,因此您可能想要测试它.

这是我使用的方法:

private static IEnumerable<string> SplitSqlStatements(string sqlScript)
{
    // Split by "GO" statements
    var statements = Regex.Split(
            sqlScript,
            @"^[\t ]*GO[\t ]*\d*[\t ]*(?:--.*)?$",
            RegexOptions.Multiline |
            RegexOptions.IgnorePatternWhitespace |
            RegexOptions.IgnoreCase);

    // Remove empties, trim, and return
    return statements
        .Where(x => !string.IsNullOrWhiteSpace(x))
        .Select(x => x.Trim(' ', '\r', '\n'));
}

如果您希望能够使用GO,则需要参考以下dll

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

然后像这样执行

 using (SqlConnection conn = new SqlConnection(connection))
 {
     Server db = new Server(new ServerConnection(conn));
     string script = File.ReadAllText(scriptPath);
     db.ConnectionContext.ExecuteNonQuery(script);      
 }

Answer 3

GO 不是SQL的一部分,它是SQL Server Management Studio为您分割脚本所做的事情.

您需要做的是将查询读入字符串然后单独拆分GO(您可能需要使用Regex)

//Its better to dispose the SqlCommand, I also switched constructors so I could re-use the SqlCommand.
using(SqlCommand command = new SqlCommand())
{
    command.Connection = connection;

    var scripts = Regex.Split(script, @"^\w+GO$", RegexOptions.Multiline);
    foreach(var splitScript in scripts)
    {
        command.CommandText = splitScript;
        command.ExecuteNonQuery();
    }
}

看看马特约翰逊的答案是不太天真地实施GO分裂.

GO不是有效的QA命令,它是批处理分隔符...它由Enterprise Manager处理以分隔SQL脚本.因此,它可以在企业管理器中工作,但不能在C#或其他外部程序的数据库调用中工作....
