Problems with reserved fields in Mysql _mysql

You have a error in your SQL syntax; Check the manual that corresponds to your MySQL server Versio This sentence is not unfamiliar to us, nothing more than "," and so on. But if you accidentally added a reserved field in MySQL as the name of the field stored in the database, the tragedy happened.

A few days ago because of the temporary changes in functionality, you need to add a field to the datasheet to distinguish the imported batches, I added the Group field to MySQL, and I didn't expect my nightmare to unfold
Originally the procedure is close to the end, this morning to the company to the program to a happy ending, did not think Every time I import an Excel table always prompts me for SQL statement errors, I change the SQL statement to add subtraction, also did not fix the error, a whole morning plus two hours in the afternoon, it is almost to the degree of madness. I was almost on my knees, but I still didn't fix the mistake.
Put the problem aside and keep doing other things. When you write a group by statement, you suddenly realize that group is a reserved word for MySQL and that this problem is solved. Remember how painful it is to understand.

Reserved fields for MySQL

In MySQL, the words in the following table are explicitly preserved. Most of these digital systems are used by standard SQL as column names and/or table names (for example, GROUP). A few are preserved because MySQL needs them, in MySQL, when the table or field name and the database name and the reserved word conflict, in the SQL statement can be enclosed in an apostrophe (), when we generally try to minimize the use of these reserved fields.
