Mismatched query and update of collection

Last modified: 03 December 2024

Reports a collection of fields or variables whose contents are either queried and not updated or updated and not queried. Such mismatched queries and updates are pointless and may indicate either dead code or a typographical error.

Query methods are automatically detected, based on whether they return something, or a callback is passed to them. Use the table below to specify which methods are update methods.
