Member Data Documentation

◆ not_required_for_equality

bool duckdb::CollateCatalogEntry::not_required_for_equality

Whether or not the collation is required for equality comparisons or not. For many collations a binary comparison for equality comparisons is correct, allowing us to skip the collation in these cases which greatly speeds up processing.

The documentation for this class was generated from the following file:
