请教mysql的问题
想只用sql而不用php代码实现如下功能:如果一条记录存在返回其id,如果不存在,插入并返回其id,可以实现吗?如何实现?望各位大侠详细指教

------解决方案--------------------
执行insert into table () values () on duplicate key update ……

那么mysql_insert_id() 返回就是自增id

不过mysql_insert_id可是php函数哦
------解决方案--------------------

SQL code
INSERT IGNORE INTO table () VALUES ();<div class="clear">
                 
              
              
        
            </div>
