      • getBooleanFromString

        final boolean getBooleanFromString​(java.lang.String source)

        Get a boolean value from a CHAR column. In order to match the embedded driver and JCC we return false iff the CHAR value is "0" or "false".

        Leading and trailing whitespace is removed from the input string before it's compared to "0" and "false". No other normalization is performed. Specifically, no case conversion is performed, so the comparison is case sensitive, and everything that doesn't exactly match "0" or "false" will be considered true.

        Parameters:
        source - the value of a CHAR column
        Returns:
        false if source is "0" or "false", true otherwise
