Extension Methods

Methods

ThenDoNothing()

Leaves the unmatched source row unwritten (DO NOTHING; PostgreSQL only).

public MergeBuilder<TEntity> ThenDoNothing()

Returns

MergeBuilder<TEntity>

The originating merge builder, for chaining further branches.

ThenInsert()

Inserts every writable column of the unmatched source row.

public MergeBuilder<TEntity> ThenInsert()

Returns

MergeBuilder<TEntity>

The originating merge builder, for chaining further branches.

ThenInsert(Expression<Func<TEntity, object?>>)

Inserts the explicitly assigned columns of the unmatched source row. The lambda body must be an anonymous initializer or a named initializer assignable to the entity; only the listed columns are inserted, so every omitted column receives its normal database default, nullability or constraint behaviour. The proposed-row (excluded) and target rows are not visible here.

public MergeBuilder<TEntity> ThenInsert(Expression<Func<TEntity, object?>> assignments)

Parameters

assignments Expression<Func<TEntity, object>>

The assignments, for example source => new { Id = source.Id, Name = source.Name }.

Returns

MergeBuilder<TEntity>

The originating merge builder, for chaining further branches.

Exceptions

ArgumentException

The body is not a supported non-empty initializer, or a destination is unknown, duplicated or type-incompatible.

NotSupportedException

A destination may not be written, or an unavailable role is referenced.
