operator fun <S, ID : EntityID<S>, E : Expression<S>> set(column: Column<ID>, value: E)

@JvmName(name = "setWithNullableEntityIdValue")

operator fun <S : Any> set(column: Column<EntityID<S>?>, value: S?)

@JvmName(name = "setWithEntityIdValue")

operator fun <S : Any> set(column: Column<EntityID<S>>, value: S)

open operator fun <S> set(column: CompositeColumn<S>, value: S)

update

open fun <T, S : T?> update(column: Column<T>, value: () -> Expression<S>)

Updates the mapping of the specified column with the value of the provided expression.

open fun <T, S : T?> update(column: Column<T>, value: Expression<S>)
