Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.mysql.com/documentation/ and the instructions on how to report a bug at http://bugs.mysql.com/how-to-report.php Additional info: According to SQL:2003, part 2 "Foundations", the syntax for the "aggregate function" is <aggregate function> ::= COUNT <left paren> <asterisk> <right paren> [ <filter clause> ] | <general set function> [ <filter clause> ] | <binary set function> [ <filter clause> ] | <ordered set function> [ <filter clause> ] <general set function> ::= <set function type> <left paren> [ <set quantifier> ] <value expression> <right paren> <set function type> ::= <computational operation> <computational operation> ::= AVG | MAX ... | COUNT ... As you can see, in parens after the COUNT one can use either a <value expression> or an <asteriks>. COUNT(c.*) is a syntax error.
