There are two data tables, one is alipay and the other is wxpay. The fields of the two tables are the same.
When a user queries recharge records, how can he use the model or DB class to query the two databases at the same time and get one result?

Two data tables are still two databases. If there are two data tables, just check it directly through the view. It is in the tp5 document. If there are two databases, one of them needs to use Db::connect("connection parameters")->query("query statement"), or directly use native syntax to query

If you do this with a large amount of data, the performance will be poor, just use jion to query the table

The problem is solved, just convert the query results into array format, and then merge the two arrays.
I have learned relatively little about MYSQL and have not used joint table queries.
