Hi all, I am a newbie and I have a question, I have a countries table with 'country_code' and 'name' fields, the table has 211 records and the database is postgres and connection is made with product Z Psycopg (also I have checked it with PoPy and the result is the same one I explain later). I have declared a ZSQLMethod(getCountriesZSQL) with a simple query: SELECT country_code,name FROM countries. At Advanced Tab's ZSQLMethod I have managed the following parameters to cache the query: Maximum rows to retrieve: 300 Maximum results to breaks: 300 Maximum Time (sec) to breaks: 5000 I have created a DMTL Method to show a combo-select of countries: <SELECT name="comboCountries"> <dtml-in getCountriesZSQL> <OPTION VALUE='<dtml-var country_code null="">'> <dtml-var name null=""> </dtml-in> </SELECT> This is my question: When I delete a record of countries table, the table changes and I think that the combo-select shouldn´t change because is cached; but, in fact, the combo-select changes soon, over he fifth or sixth page refresh. The result changes showing 210 and 211 records randomly... What is the reason of this behavior? Does anyone know what is the solution? Regards, ZRaul. Z8-)
