【IT愛好者】SQL Server自動生成INSERT語句(在SQL2005下測試通過)

這是建立一個儲存過程，通過執行這個儲存過程，將指定的資料表中的資料導成Insert語句形式

 

--這是一個可以將表中的資料自動生成INSERT語句的儲存過程
--有個BUG，如果是自動增長列，資料也會被插入
--在查詢分析器中執行完成後，可以從執行結果中自制出SQL指令碼。
IF OBJECT_ID('spGenInsertSQL','P') IS NOT NULL
DROP PROC spGenInsertSQL
GO
CREATE   proc spGenInsertSQL (@tablename varchar(256))
as
begin
declare @sql varchar(8000)
declare @sqlValues varchar(8000)
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'

                when xtype in (58,61)

                     then 'case when '+ name +' is null then ''NULL'' else '+''''''''' + ' + 'cast('+ name +' as varchar)'+ '+'''''''''+' end'

               when xtype in (167)

                     then 'case when '+ name +' is null then ''NULL'' else '+''''''''' + ' + 'replace('+ name+','''''''','''''''''''')' + '+'''''''''+' end'

                when xtype in (231)

                     then 'case when '+ name +' is null then ''NULL'' else '+'''N'''''' + ' + 'replace('+ name+','''''''','''''''''''')' + '+'''''''''+' end'

                when xtype in (175)

                     then 'case when '+ name +' is null then ''NULL'' else '+''''''''' + ' + 'cast(replace('+ name+','''''''','''''''''''') as Char(' + cast(length as varchar)  + '))+'''''''''+' end'

                when xtype in (239)

                     then 'case when '+ name +' is null then ''NULL'' else '+'''N'''''' + ' + 'cast(replace('+ name+','''''''','''''''''''') as Char(' + cast(length as varchar)  + '))+'''''''''+' end'

                else '''NULL'''

              end as Cols,name

         from syscolumns

        where id = object_id(@tablename)

      ) T
set @sql ='select ''INSERT INTO ['+ @tablename + ']' + left(@sql,len(@sql)-1)+') ' + left(@sqlValues,len(@sqlValues)-4) + ')'' from '+@tablename
print @sql
exec (@sql)
end
GO

 

執行如下語句測試結果：

exec spGenInsertSQL test
