Why is an error returned?
INSERT INTO myuser VALUES('','mijueshitai','123456',86,'meijie@qq.com','emeishan');
Check the ID to see if it grows automatically. If it grows automatically, you don’t need to write this column when writing data, that is:
INSERT INTO myuser(NAME,PWD,AGE,EMAIL,ADDR) VALUES('mijueshitai','123456',86,'meijie@qq.com','emeishan'); 另外在数据表设计的时候，尽量别使用数据库的一些关键字，如NAME。
Look at your table structure, the data type may be wrong
The value inserted is wrong. The id should be the primary key, not NULL!
