sqlserver中row_number

在SQL Server中，ROW_NUMBER()函数用于为查询结果集中的每一行分配一个唯一的序号。语法如下：
SELECT column_list, ROW_NUMBER() OVER (ORDER BY column ASC|DESC) AS row_number
FROM table_name
WHERE conditions;
其中，column_list是你希望查询的列，table_name是表名，conditions是查询条件。你可以根据需要选择升序（ASC）或降序（DESC）对列进行排序，以便为每一行分配一个序号。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
