		.or
			.add(query.columns.order_id.not.isin([1, 2, 3]))

			.add(query.exists(
					subquery.where.add(subquery.columns.orderid.eq(query.columns.order_id)).root
			))
		)

	foundset.loadRecords(query)

Methods Detailed

add(column)

Add column name to group-by clause.

Same as query.groupBy().add(join.getColumn("value"))

Parameters

• QBColumn column the column to add to the query condition

Returns: QBGroupBy

Sample

var query = datasources.db.example_data.orders.createSelect();
query.groupBy.add(query.columns.orderid) // have to group by on pk when using having-conditions in (foundset) pk queries
.root.having.add(query.joins.orders_to_order_details.columns.quantity.count.eq(0))
foundset.loadRecords(query)

add(function)

Add column name to group-by clause.

Same as query.groupBy().add(join.getColumn("value"))

Parameters

• QBColumn function the function to add to the query

Returns: QBGroupBy

Sample

var query = datasources.db.example_data.orders.createSelect();
query.groupBy.add(query.columns.orderid) // have to group by on pk when using having-conditions in (foundset) pk queries

foundset.loadRecords(query)

addPk()

Add the tables' primary pk columns in alphabetical order to the group by clause.

Returns: QBGroupBy

Sample

var query = datasources.db.example_data.orders.createSelect();
query.groupBy.addPk() // have to group by on pk when using having-conditions in (foundset) pk queries
.root.having.add(query.joins.orders_to_order_details.columns.quantity.count.eq(0))
foundset.loadRecords(query)

clear()

Clear the to group-by clause.
