Mongo शेल में वर्तमान डेटाबेस के सभी कलेक्शन लिस्ट करने के दो तरीके हैं:
तरीका 1: getCollectionNames() फंक्शन
db.getCollectionNames();
तरीका 2: show collections कमांड
show collections;
उदाहरण
> db.getCollectionNames();
आउटपुट (ऐरे फॉर्मेट):
["ConvertStringToDateDemo", "IdUpdateDemo", "ProductsInformation", "addFieldDemo", "addNewFieldToEveryDocument", "arrayInnerElementsDemo", "arrayLengthGreaterThanOne", "arrayOfArraysDemo", "caseInsensitiveDemo", "changeDataType", "changeType", "charactersAllowedDemo", "charactersDemo", "checkFieldContainsStringDemo", "checkSequenceDemo", "combinationOfArrayDemo", "conditionalSumDemo", "convertStringToNumberDemo", "copyThisCollectionToSampleDatabaseDemo", "countDemo", "createSequenceDemo", "distinctCountValuesDemo", "distinctRecordDemo", "distinctWithMultipleKeysDemo", "employeeInformation", "filterArray", "findAllDuplicateKeyDocumentDemo", "findByMultipleArrayDemo", "findDuplicateByKeyDemo", "findDuplicateRecordsDemo", "findSpecificValue", "findValueInArrayWithMultipleCriteriaDemo", "getLastNRecordsDemo", "getParticularElementFromArrayDemo", "getPartuclarElement", "getSizeOfArray", "groupByDateDemo", "incrementValueInNestedArrayDemo", "insertIfNotExistsDemo", "nestedArrayDemo", "notLikeOpeartorDemo", "regExpOnIntegerDemo", "removeArrayDemo", "removeArrayElement", "removeArrayElements", "removeDuplicateDocumentDemo", "removeElementFromDoublyNestedArrayDemo", "removeFieldCompletlyDemo", "removeObject", "renameFieldDemo", "reverseRegexDemo", "searchArrayDemo", "selectSingleFieldDemo", "singleFieldDemo", "sortDemo", "sortInnerArrayDemo", "sourceCollection", "stringFieldLengthDemo", "test.js", "uniqueIndexOnArrayDemo", "unwindOperatorDemo", "updateExactField", "updateIdDemo", "updateObjects"]
> show collections;

दोनों समान परिणाम देते हैं - getCollectionNames() ऐरे लौटाता है, show collections पठनीय लिस्ट दिखाता है।
