Doctrine automatically creates table names from the record class names. For this reason, it is recommended to name your record classes using the following rules: * Use CamelCase naming * Underscores are allowed * The first letter must be capitalized * The class name cannot be one of the following (these keywords are reserved in DQL API): SELECT, FROM, WHERE, UPDATE, DELETE, JOIN, OUTER, INNER, LEFT, GROUP, ORDER, BY, HAVING, FETCH, DISTINCT, OBJECT, NULL, TRUE, FALSE, NOT, AND, OR, BETWEEN, LIKE, IN, AS, UNKNOWN, EMPTY, MEMBER, OF, IS, ASC, DESC, AVG, MAX, MIN, SUM, COUNT, MOD, UPPER, LOWER, TRIM, POSITION, CHARACTER_LENGTH, CHAR_LENGTH, BIT_LENGTH, CURRENT_TIME, CURRENT_DATE, CURRENT_TIMESTAMP, NEW, EXISTS, ALL, ANY, SOME. Example. My_PerfectClass If you need to use a different naming schema, you can override this using the setTableName() method in the setTableDefinition() method.
