我想开发一个应用程序，从SQL语句中提取表依赖项，特别是SQL from子句和Join子句中引用的表

例如，SQL SELECT stmt如下所示：

SELECT .... FROM <Table name> JOIN <list of tables and join condition> WHERE... GROUP BY ... ORDER BY... LIMIT ....

及

SELECT .... FROM <Table name> JOIN <list of tables and join condition> WHERE a > (SELECT count(c) FROM ... )

SELECT .... FROM <Table name> JOIN <list of tables and join condition> ...

insert into AbbrNames(AbbrName) select substring(LongName from 1 for 3) from LongNames

SELECT EXTRACT(month FROM order_date) "Month", COUNT(order_date) "No. of Orders" FROM orders GROUP BY EXTRACT(month FROM order_date) ORDER BY "No. of Orders" DESC;
