IDBDatabase.deleteObjectStore()

The deleteObjectStore() method of the IDBDatabase interface destroys the object store with the given name in the connected database, along with any indexes that reference it.

As with IDBDatabase.createObjectStore, this method can be called only within a versionchange transaction.

Note: This feature is available in Web Workers

Syntax

dbInstance.deleteObjectStore(name);

Parameters

name

The name of the object store you want to delete.

Exceptions

This method may raise a DOMException  of one of the following types:

Exception Description
InvalidStateError Occurs if the method was not called from a versionchange transaction callback. For older WebKit browsers, you must call first.
TransactionInactiveError Occurs if a request is made on a source database that doesn't exist (e.g. has been deleted or removed.) In Firefox previous to version 41, an InvalidStateError was raised in this case as well, which was misleading; this has now been fixed (see bug 1176165.)
NotFoundError You are trying to delete an object store that does not exist. Names are case sensitive.

Example

var dbName = "sampleDB";
var dbVersion = 2;
var request = indexedDB.open(dbName, dbVersion);

request.onupgradeneeded = function(e) {
  var db = request.result;
  if (e.oldVersion < 1) {
    db.createObjectStore("store1");
  }

  if (e.oldVersion < 2) {
    db.deleteObjectStore("store1");
    db.createObjectStore("store2");
  }

  // etc. for version < 3, 4...
};
