In the database, "Hint" is an instruction that instructs the query optimizer to execute a plan. By embedding hints in SQL statements, you can influence the optimizer's decision to select the desired execution path. Here is a background example using Hint:
Suppose you have a table that contains a large amount of data, and you know that in some specific circumstances, the join order of the tables in a query may affect query performance. Leading Hint allows you to specify the order of table joins that you want the optimizer to follow.

# 背景
在数据库中,"Hint" 是一种用于指导查询优化器执行计划的指令。通过在SQL语句中嵌入Hint,可以影响优化器的决策,以选中期望的执行路径。以下是一个使用Hint的背景示例:
假设有一个包含大量数据的表,而你知道在某些特定情况下,在一个查询中,表的连接顺序可能会影响查询性能。Leading Hint允许你指定希望优化器遵循的表连接的顺序。
