Interface IUpsertInsertSpec<TTarget>
Fluent configuration builder for the INSERT branch of an Upsert operation. Inherits
Set / Ignore from IEntityInsertSpec<TTarget, TBuilder>
(with itself substituted as TBuilder, so chain methods return
IUpsertInsertSpec<TTarget>) and adds the Upsert-only chain methods
When(Expression<Func<TTarget, bool>>) / DoNothing(), which have no SQL meaning outside MERGE /
ON CONFLICT.
public interface IUpsertInsertSpec<TTarget> : IEntityInsertSpec<TTarget, IUpsertInsertSpec<TTarget>> where TTarget : notnull
Type Parameters
TTargetTarget table record type.
- Inherited Members
- Extension Methods
Remarks
This interface is used only as the receiver type of an expression tree captured by linq2db. The configure expression is parsed by linq2db and is not invoked; implementing this interface is not a supported extension point.
Methods
DoNothing()
Marks the INSERT branch as explicitly empty.
