A = B | All primitive types | TRUE if expression A is equal to expression B otherwise FALSE | ||
A <=> B | All primitive types | Returns same result with EQUAL(=) operator for non-null operands, but returns TRUE if both are NULL, FALSE if one of the them is NULL (as of version 0.9.0) | ||
A == B | None! | Fails because of invalid syntax. SQL uses =, not == | ||
A <> B | All primitive types | NULL if A or B is NULL, TRUE if expression A is NOT equal to expression B otherwise FALSE | ||
A < B | All primitive types | NULL if A or B is NULL, TRUE if expression A is less than expression B otherwise FALSE | ||
A <= B | All primitive types | NULL if A or B is NULL, TRUE if expression A is less than or equal to expression B otherwise FALSE | ||

A IS NOT NULL | All types | FALSE if expression A evaluates to NULL otherwise TRUE | ||
A LIKE B | strings | NULL if A or B is NULL, TRUE if string A matches the SQL simple regular expression B, otherwise FALSE. The comparison is done character by character. The _ character in B matches any character in A(similar to . in posix regular expressions) while the % character in B matches an arbitrary number of characters in A(similar to .* in posix regular expressions) e.g. 'foobar' like 'foo' evaluates to FALSE where as 'foobar' like 'foo_ _ _' evaluates to TRUE and so does 'foobar' like 'foo%' | ||
A RLIKE B | strings | NULL if A or B is NULL, TRUE if string A matches the Java regular expression B(See Java regular expressions syntax), otherwise FALSE e.g. 'foobar' rlike 'foo' evaluates to FALSE where as 'foobar' rlike '^f.*r$' evaluates to TRUE | ||
A REGEXP B | strings | Same as RLIKE |
