sqlserver 導(dǎo)出插入腳本代碼

工作中經(jīng)常遇到需要將遠(yuǎn)程客戶(hù)數(shù)據(jù)庫(kù)中的數(shù)據(jù)復(fù)制到本地來(lái)測(cè)試，下載整個(gè)數(shù)據(jù)庫(kù)太大了不值得，用下面的腳本可以按指定表生成Insert腳本，將腳本復(fù)制到本地來(lái)執(zhí)行，這樣快捷了不少

當(dāng)然有其它工具可以做這件事，但如果客戶(hù)不允許你在服務(wù)器亂裝東西時(shí)這個(gè)腳本就會(huì)有用了。

復(fù)制代碼代碼如下:

 
DECLARE @tbImportTables table(tablename varchar(128), deleted tinyint) 

-- append tables which you want to import 
Insert Into @tbImportTables(tablename, deleted) values('tentitytype', 1) 
Insert Into @tbImportTables(tablename, deleted) values('tattribute', 1) 
-- append all tables 
--Insert Into @tbImportTables(tablename, deleted) select table_name, 1 from INFORMATION_SCHEMA.tables where table_type = 'BASE TABLE' 

DECLARE @tbImportScripts table(script varchar(max)) 

Declare @tablename varchar(128), 
@deleted tinyint, 
@columnname varchar(128), 
@fieldscript varchar(max), 
@valuescript varchar(max), 
@insertscript varchar(max) 

Declare curImportTables Cursor For 
Select tablename, deleted 
From @tbImportTables 

Open curImportTables 
Fetch Next From curImportTables Into @tablename, @deleted 

WHILE @@Fetch_STATUS = 0 
Begin 
　　If (@deleted = 1) 
　　begin 
　　　　Insert into @tbImportScripts(script) values ('Truncate table ' + @tablename) 
　　end 

　　Insert into @tbImportScripts(script) values ('SET IDENTITY_INSERT ' + @tablename + ' ON') 

　　set @fieldscript = '' 
　　select @fieldscript = @fieldscript + column_name + ',' from INFORMATION_SCHEMA.columns where table_name = @tablename and data_type not in('timestamp', 'image') 
　　set @fieldscript = substring(@fieldscript, 0, len(@fieldscript)) 

　　set @valuescript = '' 
　　select @valuescript = @valuescript + 'case when ' + column_name + ' is null then ''null'' else '''''''' + convert(varchar(max), ' + column_name + ') + '''''''' end +'',''+' 　　from INFORMATION_SCHEMA.columns where table_name = @tablename and data_type not in('timestamp', 'image') 
　　set @valuescript = substring(@valuescript, 0, len(@valuescript) - 4) 

　　set @insertscript = 'select ''insert into ' + @tablename + '(' + @fieldscript + ') values(' + '''+' + @valuescript + ' + '')'' from ' + @tablename 
　　Insert into @tbImportScripts(script) exec ( @insertscript) 

　　Insert into @tbImportScripts(script) values ('SET IDENTITY_INSERT ' + @tablename + ' OFF') 

　　Insert into @tbImportScripts(script) values ('GO ') 
　　Fetch Next From curImportTables Into @tablename, @deleted 
End 

Close curImportTables 
Deallocate curImportTables 

Select * from @tbImportScripts
