两个表 a表字段 1 2 3 4 b表字段 11 22 33 44 select * from a,b where a.1=b.11 and 2='0' 这个可以正常执行 select * from a,b where a.1=b.11 and 3='0' 这个就提示Ambiguous column(3),如果加上a.3='0'就没有问题,但是现在因为一些原因 不能用a.3,该怎么办?到底是哪里的问题,请各位兄弟帮忙看看。
it's easy to use #ifdef MAX #...... #endif but how about a predined max(a,b) ((a)>(b) ? (a) : (b)) ? #ifdef max or #ifdef max(a,b) or something else? if it's #ifdef max(a,b), does C compiler check whether the paramenters must be a,b? like, #ifdef max(x,y) ? i'm confused, but hopefully i made myself clear. thank you in advance.
