If you encounter this problem today, record that you have created this’ model ‘field in the database and used querywrapper to initialize the query,   And then I reported this mistake,     Then I go to the database to query with SQL statements executed by the system;   It turned out that it was still a mistake   1054 – Unknown column ‘model’ in ‘field list’   ,
After that, use “*”   To query can directly find the data;   The field “model” also exists,   I don’t know what this is,   But locate the problem, start to modify the field. Then there is no problem
Other tables I created have the ‘model’ field, but this problem does not occur
But this is still a question,   After reading the explanation of other blogs, I found that I didn’t have the answer I wanted

Hope to have big guys see trouble to teach younger brother, also hope in the future I can give myself a direct answer~

Wrong report

Then I go to the database and query with the SQL statement executed by the system

It turned out to be a mistake   1054 – Unknown column ‘model’ in ‘field list’

After that, use “*”   To query, you can directly find the data. This field “model” also exists,

Other tables I created have the ‘model’ field, but they can be found directly
