Sql Server RowNumber和表变量分页性能优化小计

直接让代码了，对比看看就了解了

当然，这种情况比较适合提取字段较多的情况，要酌情而定

 

性能较差的：

?

WITH #temp AS                      

(                                   

Select column1,column2,column3,column4,column5,column6,column7,column8,column9,column10, row_number() over (Order by column100 desc) as RowNumber                                    

From tables1

Where .....                                 

)                                    

SELECT  *

FROM #temp

WHERE RowNumber BETWEEN 1601 and 1620 

ORDER BY RowNumber

 

优化后，性能较好的

?

WITH #temp AS                      

(                                   

Select column1, row_number() over (Order by column100 desc) as RowNumber                                    

From tables1

Where .....                                 

)                                    

SELECT  column1,column2,column3,column4,column5,column6,column7,column8,column9,column10

FROM tables1

where column1 in

(

select column1 from #temp

WHERE RowNumber BETWEEN 1601 and 1620                   

ORDER BY RowNumber

)
