FMResultSet * result = [sDB executeQuery:@"select * from rockTB"];

while ([result next])

{

NSString * time = [result stringForColumn:@"time"];

NSString * body = [result stringForColumn:@"body"];

int myId = [result intForColumn:@"myId"];

NSLog(@"time:%@ body:%@ myId:%d",time,body,myId);

}

3.更新

NSString * str = [NSString stringWithFormat:@"update rockTB SET title = '%@' ,body = '%@' WHERE myId = %d",

info.title, info.body, info.aId];

BOOL ret = [sDB executeUpdate:str];
