For row comparisons, (a, b) = (x, y) is equivalent to: NULL -safe equal. This operator performs an equality comparison like the = operator, but returns 1 rather than NULL if both operands are NULL, and 0 rather than NULL if one operand is NULL. DISTINCT FROM operator. y) is equivalent to: Not equal: y) and (a, b) != (x, y) are equivalent to:

Jun 14, 2012 · It's a perfectly valid question. You need to use WHERE idParticipant IN (118, 119); My guess is that MySQL is implicitly converting the value of 119 to a Boolean true value, so you are saying: WHERE idParticipant = 118 OR TRUE;, thus including all the rows.
