您可以使用以下查询

SELECT *
 FROM(
     SELECT ROW_NUMBER() OVER (ORDER BY [OrderBYColumn]) AS SrNo, 
             <Column1,Column2,Column3 ....> 
     FROM 
         TableName

SELECT *
 FROM(
     SELECT ROW_NUMBER() OVER (ORDER BY [OrderBYColumn]) AS SrNo, 
             <Column1,Column2,Column3 ....> 
     FROM
