由以下代码抛出:
final UUID id = UUID.randomUUID();
final double frequency = 8_000.0 + ( 10_000.0 * Math.random() );
final double startSec = 100*i;
final double startNano = 10*i;
final double endSec = startSec + ( 100*i );
final double endNano = startNano + ( 10*i );
final double latitude = ( 180.0*Math.random() ) - 90.0;
final double longitude = ( 360.0*Math.random() ) - 180.0;
final Document trackID = new Document(
"id", new Document(
"msb", id.getMostSignificantBits ()) .append(
"lsb", id.getLeastSignificantBits()));
final Document track = new Document(
"id", new Document(
"msb", id.getMostSignificantBits ()) .append(
"lsb", id.getLeastSignificantBits())).append(
"frequency", frequency ) .append(
"start", new Document(
"seconds", startSec ) .append(
"nanoSec", startNano )).append(
"end", new Document(
"seconds", endSec ) .append(
"nanoSec", endNano )).append(
"position", new Document(
"latitude" , latitude ) .append(
"longitude", longitude )).append(
"padding", new byte[1000-8-8-8-4-4-4-4-8-8] );
//_collection.insertOne( track );
_collection.updateOne(
trackID,
track,
new UpdateOptions().upsert( true ));
注释代码 _collection.insertOne( track ); 执行良好。
为什么插入没问题,而“upsert”却不行?
最佳答案
updateOne 用于使用更新运算符更新文档字段。您需要 replaceOne 来获取替换文档。
_collection.replaceOne(
trackID,
track,
new UpdateOptions().upsert( true ));

我正在学习Rails,并阅读了关于乐观锁的内容。我已将类型为integer的lock_version列添加到我的articles表中。但现在每当我第一次尝试更新记录时,我都会收到StaleObjectError异常。这是我的迁移:classAddLockVersionToArticle当我尝试通过Rails控制台更新文章时:article=Article.first=>#我这样做:article.title="newtitle"article.save我明白了:(0.3ms)begintransaction(0.3ms)UPDATE"articles"SET"title"='dwdwd

我早就知道Ruby中的“常量”(即大写的变量名)不是真正常量。与其他编程语言一样,对对象的引用是唯一存储在变量/常量中的东西。(侧边栏:Ruby确实具有“卡住”引用对象不被修改的功能,据我所知,许多其他语言都没有提供这种功能。)所以这是我的问题:当您将一个值重新分配给常量时,您会收到如下警告:>>FOO='bar'=>"bar">>FOO='baz'(irb):2:warning:alreadyinitializedconstantFOO=>"baz"有没有办法强制Ruby抛出异常而不是打印警告?很难弄清楚为什么有时会发生重新分配。 最佳答案
