Methods

TryConvertToArray(ShapedQueryExpression, out SqlExpression?, bool, bool)

If the given source wraps a ValuesExpression without any additional clauses (e.g. filter, ordering...), converts that to a NewArrayExpression and returns that.

public static bool TryConvertToArray(this ShapedQueryExpression source, out SqlExpression? array, bool ignoreOrderings = false, bool ignorePredicate = false)

Parameters

source ShapedQueryExpression

array SqlExpression

ignoreOrderings bool

ignorePredicate bool

Returns

bool
