Documents and Collections To insert an element at a different position in the array, use the  arrayInsert()  method to specify which index to insert in the path expression. In this case, the index is 0, or the first element in the array. To delete an element from the array, you must pass to the  arrayDelete()  method the index of the element to be deleted. You can use the  remove()  method to delete some or all documents from a collection in a schema. The X DevAPI provides additional methods for use with the  remove()  method to filter and sort the documents to be removed. The following example passes a search condition to the  remove()  method. All documents matching the condition are removed from the  countryinfo  collection. In this example, one document matches the condition. To remove the first document in the  countryinfo  collection, use the  limit()  method with a value of 1. The following example removes the last document in the  countryinfo  collection by country name. You can remove all documents in a collection. To do so, use the  remove("true")  method without specifying a search condition. Use care when you remove documents without specifying a search condition. This action deletes all documents from the collection. Alternatively, use the  db.drop_collection(’countryinfo’)  operation to delete the  countryinfo collection. •See CollectionRemoveFunction for the full syntax definition. mysql-js>  db.countryinfo.remove("true").sort(["Name desc"]).limit(1) mysql-js>  db.countryinfo.remove("true").limit(1) mysql-js>  db.countryinfo.remove("Code = ’SEA’") mysql-js>  db.countryinfo.modify("Name = ’France’").arrayInsert("$.Airports[0]", "CDG") mysql-js>  db.countryinfo.modify("Name = ’France’").arrayDelete("$.Airports[1]") •The MySQL Reference Manual provides instructions to help you search for and modify JSON values. •See CollectionModifyFunction for the full syntax definition.
