SQL错误属性（列）名称

Question

I've created table in MySQL database with the query:

CREATE TABLE IF NOT EXISTS `CREW` (
`ID` INT NOT NULL,
`CALL` VARCHAR(45) NULL DEFAULT NULL,
PRIMARY KEY (`ID`));

And it did work perfectly, but when I tried to:

INSERT INTO CREW (ID, CALL) VALUES (0, 'None');

I've got ERROR 1064 . What are the other bad names for attributes that we should avoid?

Answer 1

You should do it like you did it in your create statement. Sourround the attribute names and the table names with backticks:

INSERT INTO `CREW` (`ID`, `CALL`) VALUES (0, 'None');

If you do it always like this, you don't need to avoid any names.

Answer 2

1. It's called a column, not an attribute ;)

2. Don't use reserved words for column names. MySQL list here: https://dev.mysql.com/doc/refman/5.0/en/reserved-words.html . Multi-db list here: https://www.drupal.org/node/141051

3. If you want your SQL to be compatible with other databases, you should use lower snake_case

Answer 3

One of the column name is 'CALL' in your CREW table. The CALL statement used to invoke a stored procedure. So when you are executing

INSERT INTO CREW (ID, CALL) VALUES (0, 'None');

Mysql understand that you are some how trying to execute a stored procedure. So you need to Surround the attribute names with back-ticks

INSERT INTO CREW ('ID', 'CALL') VALUES (0, 'None');
