Class DurationAttribute

Namespace
NextORM.Core
Assembly
nextorm.core.dll

Declares how a TimeSpan property is stored. On a provider with a native duration type (PostgreSQL interval, MySQL/MariaDB TIME) the unit is ignored and the value is stored natively; on a provider without one (SQL Server, SQLite, ClickHouse) the value is stored in an integer column in Unit, defaulting to Ticks.
