public sealed class UnionQuery<TResult>

Type Parameters

TResult

The common result shape.

Properties

All

Whether duplicates are kept (UNION ALL) or collapsed (UNION).

public bool All { get; }

Property Value

bool

Branches

The branches, in order.

public IReadOnlyList<UnionBranch<TResult>> Branches { get; }

Property Value

IReadOnlyList<UnionBranch<TResult>>

Limit

The maximum number of combined rows, when set.

public int? Limit { get; }

Property Value

int?

Offset

The number of combined rows skipped, when set.

public int? Offset { get; }

Property Value

int?

Order

The combined ordering over projected members, in order.

public IReadOnlyList<UnionOrder> Order { get; }

Property Value

IReadOnlyList<UnionOrder>

Methods

OrderBy(Expression<Func<TResult, object?>>)

Orders the combined result by a projected member, ascending.

public UnionQuery<TResult> OrderBy(Expression<Func<TResult, object?>> member)

Parameters

member Expression<Func<TResult, object>>

The projected member.

Returns

UnionQuery<TResult>

OrderByDescending(Expression<Func<TResult, object?>>)

Orders the combined result by a projected member, descending.

public UnionQuery<TResult> OrderByDescending(Expression<Func<TResult, object?>> member)

Parameters

member Expression<Func<TResult, object>>

The projected member.

Returns

UnionQuery<TResult>

Skip(int)

Skips count combined rows — applied after the union, on the store, with Take(int).

public UnionQuery<TResult> Skip(int count)

Parameters

count int

The number of rows skipped.

Returns

UnionQuery<TResult>

Take(int)

Limits the combined result to count rows — applied after the union, on the store.

public UnionQuery<TResult> Take(int count)

Parameters

count int

The maximum number of rows.

Returns

UnionQuery<TResult>
