→XQuery Locking Options
Custom locks can be acquired by setting the BaseX-specific XQuery options {{Code|query:read-lock}} and {{Code|query:write-lock}}. Multiple option declaration may occur in the prolog of a query, but multiple values can also be separated with commas in a single declaration. These locks are in another namespace than the database names: the lock value {{Code|factbook}} will not lock a database named factbook.
These option declarations will put read locks on ''foo'', ''bar'' and ''batz'' and a write lock on ''quix''.:
