db.collection.getIndexes()¶
On this page
Definition¶
- db.collection.getIndexes()¶
Returns an array that holds a list of documents that identify and describe the existing indexes on the collection. You must call db.collection.getIndexes() on a collection. For example:
db.collection.getIndexes()
Change collection to the name of the collection for which to return index information.
Considerations¶
在 3.0.0 版更改.
For MongoDB 3.0 deployments using the WiredTiger storage engine, if you run db.collection.getIndexes() from a version of the mongo shell before 3.0 or a version of the driver prior to 3.0 compatible version, db.collection.getIndexes() will return no data, even if there are existing indexes. For more information, see WiredTiger and Driver Version Compatibility.
Required Access¶
The user executing the method requires either find privileges on the system.indexes collection or the listIndexes privilege action. At a minimum, the read built-in role provide the requisite permissions.
Output¶
db.collection.getIndexes() returns an array of documents that hold index information for the collection. Index information includes the keys and options used to create the index. For information on the keys and index options, see db.collection.createIndex().
