表中的資料匯出為insert語句的簡單方法

因項目需要，有時要求將一個表中的記錄匯出來，結合網上搜尋的一些代碼，而成此文 。因時間過長已找不出原創作者，謹請原諒

Create procedure pGetInsertSQL (@tablename varchar(256))
---WITH ENCRYPTION
as
begin
---得到表中的SQL
 -- declare @tablename varchar(256)
 -- set @tablename = 'Design_DBPageStruct'
 --Create Table SQLtmp
 --(
 --sql varchar(4000)
 --)
---Delete  from SQLtmp

if not exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[SQLtmp]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
Create Table SQLtmp
(
sql varchar(4000)
)

  declare @sql varchar(4000)
  declare @sqlValues varchar(4000)
  set @sql =' ('
  set @sqlValues = 'values (''+'
  select @sqlValues = @sqlValues + cols + ' + '','' + ' ,@sql = @sql + '[' + name + '],'
  from
    (select case
            when xtype in (48,52,56,59,60,62,104,106,108,122,127)                               
                 then 'case when '+ name +' is null then ''NULL'' else ' + 'cast('+ name + ' as varchar)'+' end'

---Select sql from SQLtmp
---Select sql from SQLtmp  FOR XML AUTO

應用方法

Create Procedure pBackInsertSQL
As
Begin
if not exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[SQLtmp]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
Create Table SQLtmp
(
sql varchar(4000)
)
else
Truncate Table SQLtmp

print '正在備份表' + 'Cfg_DataDictionary'
Execute pGetInsertSQL 'Cfg_DataDictionary'

print '插入中間分隔字元'
Insert into SQLtmp(sql) values ('*************************************')

print '正在備份表' + 'Shuttle'
Execute pGetInsertSQL 'Shuttle'

print '插入中間分隔字元'
Insert into SQLtmp(sql) values ('*************************************')

print '正在備份表' + 'Shuttle_Param'
Execute pGetInsertSQL 'Shuttle_Param'

print '插入中間分隔字元'
Insert into SQLtmp(sql) values ('*************************************')

Declare @Cnt varchar(10)
Select @Cnt = convert(varchar(10),count(sql)) From SQLtmp

Print '共計備份資料 '+@Cnt + '條'
End
