MongoDB-এ ডেটাবেস সিলেক্ট করে সংগ্রহের তালিকা দেখানো
MongoDB-এ কোনো নির্দিষ্ট ডেটাবেসের সব সংগ্রহ (কালেকশন) দেখতে প্রথমে use কমান্ড দিয়ে ডেটাবেস সিলেক্ট করতে হয়, তারপর db.getCollectionNames() বা show collections কমান্ড ব্যবহার করুন।
সিনট্যাক্স
use yourDatabaseName; db.getCollectionNames();
উদাহরণ: 'web' ডেটাবেসের সংগ্রহগুলো দেখানো
> use web; switched to db web > db.getCollectionNames();
