sqlserver 導(dǎo)出插入腳本代碼

工作中經(jīng)常遇到需要將遠(yuǎn)程客戶數(shù)據(jù)庫中的數(shù)據(jù)復(fù)制到本地來測(cè)試，下載整個(gè)數(shù)據(jù)庫太大了不值得，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。
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
