SQL Server 合并SQL脚本文件的方法的解决办法

这篇文章主要为大家详细介绍了SQL Server 合并SQL脚本文件的方法的简单示例，具有一定的参考价值，可以用来参考一下。

对此感兴趣的朋友，看看idc笔记做的技术笔记！

代码如下:

 
use master 
Go 
if object_id('sp_ScriptMerge') Is Not Null 
Drop proc sp_ScriptMerge 
Go 
Create Proc sp_ScriptMerge 
( 
@Path nvarchar(1024), 
@FilesList nvarchar(max)= null, 
@NewFileName nvarchar(1024)=null 
) 
As 
/*合并SQL脚本文件(SQL)V1.0 Andy 2011-9-1*/ 
Declare 
@ScriptNr nchar(21), 
@subdirectoryStr nvarchar(512),

@ScriptCount int 
Declare @subdirectoryTB Table (subdirectory nvarchar(512),depth smallint,[file] smallint) 
Declare @tmp table(row smallint identity primary key,fileName nvarchar(512)) 
Set Nocount on 
if right(@Path,1)<>'\' Set @Path=@Path+'\' 
If Isnull(@NewFileName,'')='' Set @NewFileName=N'合并脚本-'+Convert(nvarchar(8),getdate(),112) 
if lower(right(@NewFileName,4))<>'.sql' Set @NewFileName=@NewFileName+'.sql' 
Set @NewFileName=@Path+@NewFileName 
Set @ScriptNr='Nr: '+Replace(replace(Replace(replace(convert(nvarchar(23),getdate(),121),'-',''),':',''),' ',''),'.','') 
Set @ScriptCount=0 
/*读取脚本文件内容*/ 
if @FilesList >'' 
Begin 
Set @FilesList='Select N'''+replace(@FilesList,',',''' Union All Select N''')+'''' 
Insert into @tmp([fileName]) Exec(@FilesList) 
End 
if object_id('Tempdb..#') Is Not Null Drop Table # 
Create table #(row int identity(1,1) Primary key,text nvarchar(max)) 
Insert into @subdirectoryTB Exec xp_dirtree @Path,1,1 
Declare cur_file cursor for

From @subdirectoryTB As a 
left Join @tmp As b ON b.fileName=a.subdirectory 
Where a.[file]=1 And a.subdirectory like '%.sql' 
And (b.fileName=a.subdirectory Or Not Exists(Select 1 From @tmp)) 
Order By isnull(b.row,0),a.subdirectory 
Open cur_file 
fetch next From cur_file into @subdirectoryStr 
While @@FETCH_STATUS = 0 
Begin 
Set @ScriptCount=@ScriptCount+1 
Insert into #(text) Select +Char(13)+Char(10)+ N'Go'+Char(13)+Char(10)+ N'/* '+@ScriptNr+' ('+rtrim(@ScriptCount)+'): '+@subdirectoryStr+' */'+Char(13)+Char(10)+ N'Go'+Char(13)+Char(10) 
Set @Dir='Type '+@Path+'"'+@subdirectoryStr+'"' 
Insert into #(text) 
Exec sys.xp_cmdshell @Dir 
fetch next From cur_file into @subdirectoryStr 
End 
Close cur_file 
Deallocate cur_file 
if @ScriptCount >0 Insert into #(text) Select +Char(13)+Char(10)+ N'Go'+Char(13)+Char(10)+ N'/* '+@ScriptNr+' 合并完成(合计 '+rtrim(@ScriptCount)+' 各脚本文件). */'+Char(13)+Char(10)+ N'Go'+Char(13)+Char(10) 
/*写入合并脚本文件*/ 
if @ScriptCount>0 
Begin 
Declare @object int, 
@FileID int, 
@hr int, 
@src varchar(255), 
@desc varchar(255), 
@row int, 
@text nvarchar(max) 
Exec @hr=sp_OACreate 'Scripting.FileSystemObject',@object output 
If @hr <> 0 Goto File_ErrorHandler 
Exec @hr = sp_OAMethod @object,'CreateTextFile',@FileID OUTPUT, @NewFileName 
If @hr <> 0 Goto File_ErrorHandler 
Set @row=1 
While Exists(Select 1 From # Where row=@row) 
Begin 
Set @text=(Select text From # Where row=@row) 
Exec @hr = sp_OAMethod @FileID, 'WriteLine', NULL, @text 
Set @row=@row +1 
End 
Goto File_Done 
File_ErrorHandler: 
Print N'*********** 读写文件的时候发生错误 ***********' 
Exec @hr=sp_OAGetErrorInfo @object, @src OUT, @desc OUT 
Select convert(varbinary(4),@hr) As hr, @src As Source, @desc As Description 
File_Done: 
Exec @hr = sp_OADestroy @FileID 
Exec @hr = sp_OADestroy @object 
Print N'*********** 合并脚本完成 ***********' 
Print N'合并后脚本文件: '+@NewFileName 
End 
Go 

代码如下:

代码如下:

 
Exec sys.sp_configure @configname = 'show advanced options',@configvalue = 1 
reconfigure 
go 
Exec sys.sp_configure @configname = 'xp_cmdshell',@configvalue = 1 
reconfigure 
Go 
Exec sys.sp_configure @configname = 'Ole Automation Procedures',@configvalue = 1 
reconfigure 
Go 

代码如下:

 
use master

@FilesList = '', -- nvarchar(max)

} 
} 
// 2.合并脚本 
SqlContext.Pipe.Send("【SQL脚本文件列表】:\n--------------------------------------------"); 
StreamWriter SW = new StreamWriter(Path + @"\" + NewFileName, true, Encoding.Unicode); //使用Unicode编码 
SW.WriteLine(@"Go\n/*============ " + strScriptNr + "====Start===================================*/\nGo\n"); //记录生成的合并脚本编号&合并动作的开始位置

} 
catch (System.Exception e) 
{ 
SqlContext.Pipe.Send("\n在方法SQLScriptMerge内发生错误： \n\n" + e.ToString()); 
} 
} 
} 

代码如下:

Exec sp_configure 'clr enable',1 
Go 
Reconfigure 
GO 
--先设置数据库选项
