Answer 1

You have a syntax error - instead of VALUE type VALUES.

Also you are not properly escaping your sql params thus leading yourself open to sql injections.

Answer 2

You cannot use INSERT statement with WHERE clause in a simple query. An INSERT will create a new row with his own field lessontypeid. Maybe you are trying to perform an update.

If you want to make an insert, the correct way would be:

INSERT INTO packagebylessontype (packageid) VALUES ('A')

If you want to perform an update, then:

UPDATE packagebylessontype SET packageid = 'A' WHERE lessontypeid ='1'

Please note that I'm using WHERE clause only in UPDATE operation, as a reference to locate register to be updated.

Answer 3

好在（packageid）和VALUES之间留一个空格，我认为这可能有效，当然应该是VALUES而不是VALUE

Answer 4

尝试使用VALUES而不是VALUE $ queryAdd =“插入到packagebylessontype（packageid） VALUES （{$ value}）WHERE lessontypeid = {$ idToBeAdded}”中；“
