A JavaScript statement is executed as a query unless declareUpdate() is
called at the beginning of the statement. Calling declareUpdate with an
options argument where explicitCommit property is set to true
starts a multi-statement transaction and requires an explicit commit or
rollback to complete the transaction. If the options argument is omitted,
or the property explicitCommit property is set to false, an
update is automatically committed. XDMP-OWNTXN is thrown if the request
is in an open transaction.
declareUpdate();
var person = {name:"Jon", age:50};
xdmp.documentInsert("p.json", person);
declareUpdate({explicitCommit: true});
var person = {name:"Jon", age:50};
xdmp.documentInsert("p.json", person);
// because explicitCommit is true, you must call xdmp.commit (or
// call it in another statement that uses the transaction started
// in this statement)
xdmp.commit();
