# Class: BinarySelectQuery

Defined in: packages/core/src/models/BinarySelectQuery.ts:34

Represents a binary SELECT expression (UNION/INTERSECT/EXCEPT) composed from two SelectQuery values.

Example

const parts = [
  SelectQueryParser.parse('SELECT id, name FROM users').toSimpleQuery(),
  SelectQueryParser.parse('SELECT id, name FROM archived_users').toSimpleQuery()
];
const unionQuery = QueryBuilder.buildBinaryQuery(parts, 'union');

Parameters

query

SelectQuery

The query to append with UNION

Returns

BinarySelectQuery

A new BinarySelectQuery representing "(this) UNION query"

---

unionAll()

unionAll(query): BinarySelectQuery

Defined in: packages/core/src/models/BinarySelectQuery.ts:69

Appends another query to this binary query using UNION ALL as the operator. This creates a new BinarySelectQuery where the left side is this binary query and the right side is the provided query.

Parameters

query

SelectQuery

The query to append with UNION ALL

Returns

BinarySelectQuery

A new BinarySelectQuery representing "(this) UNION ALL query"

---

intersect()

intersect(query): BinarySelectQuery
