I think you want BETWEEN SYMMETRIC: <literal>BETWEEN SYMMETRIC</> is the same as <literal>BETWEEN</> except there is no requirement that the argument to the left of <literal>AND</> be less than or equal to the argument on the right. If it is not, those two arguments are automatically swapped, so that a nonempty range is always implied. -- Bruce Momjian <bruce@momjian.us> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. +
