Methods to implement recursive queries are: 1. Use stored procedures to implement recursive queries. Stored procedures can use loops or recursive calls to implement recursive queries; 2. Use the WITH RECURSIVE statement to specify the recursive termination conditions and recursion in the recursive expression. Recursive queries can be implemented by iterative operations; 3. Recursive queries can be implemented by connecting the table to itself and using connection conditions to limit the depth of the connection; 4. By storing the intermediate results of the recursion in a temporary table, and using loops or Recursive calls are used to iterate calculations and recursive queries can be implemented.
