在 MySQL 的 select 语句中调用存储过程

Question

I tried to write a recursive function, which is not possible. (I'm trying to check if a given row has a given ancestor somewhere in its chain). So, i wrote this check as a procedure instead. But I can't call a procedure within a select statement.

What's the solution for such a case?

Answer 1

i found a solution. it's possible to use a function which internally calls a procedure
