FMDB執(zhí)行語句
更新語句: [database executeUpdate:sqlStr values: array];
查詢語句: [database executeQuery:sqlStr values: array];
結(jié)果集合: FMResultSet *s = [database executeQuery:sqlStr values: array];
while ([s next]){
? ? NSString *str = [s stringForColumn:@"xxxx"];
? ? Int ?i = [s intForColumnIndex:5];
}
