MySQL sql as column

Question

I've got the following table

db.queries
| id        | int(10) unsigned | NO   | PRI | NULL    | auto_increment |
| name      | varchar(256)     | NO   |     |         |                |
| sql       | text             | NO   |     | NULL    |                |
| frequency | int(10) unsigned | NO   |     | 86400   |                |

I am inserting values which are as labeled, a name and a sql query like so using the MySQLdb python tool.

cur.execute("insert into db.queries (name, sql, frequency) values ('{0}', '{1}', {2})".format('some query', 'Select a query', 86400)

I've used MySQL and MySQLdb many times before and never have had these issues.

The error I'm constantly getting is as follows:

_mysql_exceptions.ProgrammingError: (1064, "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'sql, frequency) values ('MY NAME', 'Select count(*) as' at line 1")

I appreciate any help.

There's a facility for storing queries in the database: Stored procedures. Storing SQL in a database is rarely a good idea. — tadman

sql is a reserved word in MySQL, you need to put it in backticks:

cur.execute("insert into db.queries (name, `sql`, frequency) values ('{0}', '{1}', {2})".format('some query', 'Select a query', 86400)

While I guessed immediately that that was the problem, I had no recollection until I read the error message that SQL was a reserved word. Why is it reserved?

I don't know. Maybe it's used in triggers or stored functions?

Thanks, I noticed it was a reserved word right after posting this, but I didn't know that I could still use it with the backticks. Thanks for that.
