 For example: 
        single:  @"rowid = 1"                         or      @{@"rowid":@1}
 
        more:    @"rowid = 1 and sex = 0"             or      @{@"rowid":@1,@"sex":@0}
                   
                    when where is "or" type , such as @"rowid = 1 or sex = 0"
                    you only use NSString
 
        array:   @"rowid in (1,2,3)"                  or      @{@"rowid":@[@1,@2,@3]}
            
        composite:  @"rowid in (1,2,3) and sex=0 "      or      @{@"rowid":@[@1,@2,@3],@"sex":@0}
 
        If you want to be judged , only use NSString
        For example: @"date >= '2013-04-01 00:00:00'"
