在某個特定的 MongoDB 資料庫中顯示集合?
首先,使用以下語法在 MongoDB 中切換到特定資料庫,如下所示−
use yourDatabaseName; db.getCollectionNames();
讓我們實現上述語法以顯示 WEB 資料庫的集合−
> use web; switched to db web > db.getCollectionNames();
這會產生以下輸出 −
[ "2015-myCollection", "2015-yourCollection", "2019-employeeCollection", "addColumnDemo", "applyConditionDemo", "calculateAverage", "calculateSumOfDocument", "changeSimpleFieldDemo", "check", "checkFieldDemo", "collationExample", "compoundIndexDemo", "countandsumdemo", "creatingAliasDemo", "decreasetimeusingindex", "demo1", "demo10", "demo11", "demo12", "demo13", "demo14", "demo15", "demo16", "demo17", "demo18", "demo19", "demo2", "demo20", "demo21", "demo22", "demo23", "demo24", "demo25", "demo26", "demo27", "demo28.example", "demo29", "demo3", "demo30", "demo31", "demo32", "demo33", "demo34", "demo35", "demo36", "demo37", "demo38", "demo39", "demo4", "demo5", "demo6", "demo7", "demo8", "demo9", "destinationCollection", "emp_info", "emptyCollection", "extractParticularElementDemo", "getSpecificData", "getTheMaxValueDemo", "indexCreationDemo", "missingDocumentDemo", "promoteSubfieldsDemo", "pullWithPositionalOperatorDemo", "removeNullDemo", "replacevaluedemo", "searchDocumentsDemo", "searchSubFieldDemo", "sourceCollection", "splitString", "testInArray", "twoSpecificIdsDemo", "updatingDemo", "version" ]
