How will you truncate a collection in MongoDB?

Question

kindly explain about truncating a collection in MongoDB?

Answer 1

Collections in MongoDB can be easily truncated using db.collection.remove() command. It has two syntaxes. The remove method can have a query document and an optional justOne boolean.

db.collection.remove(

   <query>,

   <justOne>

)

Taking query document and an optional remove options document

db.collection.remove(

   <query>,

   {

     justOne: <boolean>,

     writeConcern: <document>,

     collation: <document>

   }

)
