  • How to enforce this constraint in sql server

    - by Jeremy
    I have a table called city, and a table called city_city. city_city correlates two city records, so it has a fromcity_id and a tocity_id. I can enforce uniqueness on fromcity_id and and tocity_id through a unique key, but how do I enforce uniqueness so that I cant insert a record if fromcity_id and tocity_id are reversed. For example, the following records are conceptually the same: id fromcity_id tocity_id 1 100 200 2 200 100

  • mysql UNION query not working

    - by kalpaitch
    What am I doing wrong with this: $sql = "SELECT * FROM content WHERE threadName LIKE '%$filter%' ORDER BY lastUpdated desc UNION SELECT * FROM content WHERE threadName NOT LIKE '%$filter%' ORDER BY lastUpdated desc"; The first statement before the UNION works well on its own, but this one above returns: mysql_fetch_array() warning - supplied argument is not a valid MySQL result resource Am I right in believing that UNION will not return duplicate entries, in which case the second SELECT statement doesn't need to have the NOT LIKE but will just return everything that wasn't listed in the first statement.
