This is working correctly, I get an integrity constraint violation if I attempt to add a row where the values of these two fields already exist in another row. In my model I've added a rule; CDb Command failed to execute the SQL statement: SQLSTATE: Integrity constraint violation: 1062 Duplicate entry 'field1Test Data-field2Test Data' for key 'foo_uk'.
The SQL statement executed was: INSERT INTO `foo` (`field1`, `field2`...etc) VALUES (:yp0, :yp1...etc) or whatever it would be)?

However, BMWP scores must be calibrated to each geographical and ecological conditions. National Polytechnic Institute, National School of Biological Science, Laboratory of Aquatic Ecosystem Health Assessment, Laboratorio de Evaluación de la Salud de Ecosistemas Acuáticos, Departamento de Zoología, ENCB, Instituto Politécnico Nacional, Ciudad de México, México The Biological Monitoring Working Party (BMWP) is among the most used bioassessment indices for aquatic ecosystems quality assessment, which assigns scores to each macroinvertebrate taxa according to their sensitivity to organic pollution.The BMWP calibrated is a suitable biomonitoring tool, allowing the detection of those zones that needs urgently a management and recovery plan.Because the Composite index is based on the monthly averages of daily closes, we made an equivalent data series for the Dow.This study reports an attempt to validate a customer well-being (CWB) index related to natural wildlife tourism.
