description The embodiment of the invention discloses a database table query method, computer equipment and a computer storage medium. When a data source is queried, a plurality of database tables can be generated according to the data source, then an adjacency list directed graph model is constructed according to the generation sequence of the plurality of database tables, and a database table queue is determined according to the adjacency list directed graph model; and sequentially inserting each database table into the query result table according to the sequence of the plurality of database tables in the database table queue to obtain a joint query result, and completing the query of the data source. Since the adjacency list directed graph model visually represents the generation sequence of the database tables, the database table queue can be quickly determined according to the adjacency list directed graph model, and then the plurality of database tables in the database table queue can be quickly summarized to obta
