Check all the employees that Lao Wang manages.The idea is as follows: First get all the parents of the old king ID of the employee ID, and then add the employee name to the results list, in the call of a magical search function, can be a magical search:CREATE definer= ' root ' @ ' localhost ' FUNCTION ' getsubordinate ' (' uid ' int) RETURNS varchar ($) CHARSET gb2312BEGINDECLARE str varchar (1000);DECLA

: adjacency List Advantages: Only the ancestor ID is stored, the storage data is small, and the structure is similar to the single linked list, which is convenient when querying the neighboring nodes. Adding a Delete node is simple. Cons: When querying multi-level structures, it seems to be inadequate. Application situation: It is applicable to the scene with little demand for multilevel query. Scenario Two: Path Enumeration Advantages: It is convenient to query multi-level structure. It is also

Summary, the way to store the path in the multi-level query is very convenient, and in the query directly subordinate to a slightly more complex point. There is also a clear drawback, that is, the size of the path is specified, so theoretically it is not possible to carry out an infinite level of storage, the larger the path value is set, the more wasted space. At this point, this
