相关疑难解决方法(0)

看来在azure站点中的documentdb允许的SQL查询中以及通过documentdb explorer(https://studiodocumentdb.codeplex.com/)不能支持"从c中选择计数(*)" .到目前为止,获得记录计数的唯一方法是从代码(见下文).但是,我们的集合中有足够的文件,现在崩溃了.有没有办法计算集合中有多少文档比我的解决方案更有效？

DocumentClient dc = GetDocumentDbClient();
var databaseCount = dc.CreateDatabaseQuery().ToList();
Database azureDb = dc.CreateDatabaseQuery().Where(d => d.Id == Constants.WEATHER_UPDATES_DB_NAME).ToArray().FirstOrDefault();

var collectionCount = dc.CreateDocumentCollectionQuery(azureDb.SelfLink).ToList();

DocumentCollection update = dc.CreateDocumentCollectionQuery(azureDb.SelfLink).Where(c => c.Id == "WeatherUpdates").ToArray().FirstOrDefault();

var documentCount = dc.CreateDocumentQuery(update.SelfLink, "SELECT * FROM c").ToList();

MessageBox.Show("Databases: " + databaseCount.Count().ToString() + Environment.NewLine
                +"Collections: " + collectionCount.Count().ToString() + Environment.NewLine
                + "Documents: " + documentCount.Count().ToString() + Environment.NewLine, 
                 "Totals", MessageBoxButtons.OKCancel);
