MySQL connection execution in Ruby error handling

Question

How do I do error handling with something like this in RoR:

conn = Person.connection
conn.execute(sql_stmt)

What if there were errors while executing the SQL?

Answer 1

The execute method is just a wrapper for the connection's query method and that will raise an Mysql::Error exception if something is wrong. If you use mysql2 instead of the older mysql gem, then I think you'll get a Mysql2::Error exception.
