.root.having.add(query.joins.orders_to_order_details.columns.quantity.count.max(10))
foundset.loadRecords(query)min
Create an aggregate min expression.
Type QBColumn a QBColumn representing the minimum aggregate function.
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.min(10))

Parameters
Object value ;
Returns: QBCondition a QBCondition representing the "greater than" comparison.
Sample
query.where.add(query.columns.flag.gt(0))isin(query)
Compare column with subquery result.
Parameters
QBPart query subquery
Returns: QBCondition a QBCondition representing the "in" comparison with a subquery.
Sample
query.where.add(query.columns.flag.isin(query2))isin(values)
Compare column with values.
Parameters
Array values array of values
Returns: QBCondition a QBCondition representing the "in" comparison with a list of values.
Sample
query.where.add(query.columns.flag.isin([1, 5, 99]))isin(customQuery, args)
Compare column with custom query result.
Parameters
Returns: QBCondition a QBCondition representing the "in" comparison with a custom query and arguments.
Sample
query.where.add(query.columns.ccy.isin("select ccycode from currencies c where c.category = " + query.getTableAlias() + ".currency_category and c.flag = ?", ['T']))le(value)
Compare column with a value or another column. Operator: lessThanOrEqual
Parameters
Object value ;
Returns: QBCondition a QBCondition representing the "less than or equal to" comparison.
Sample
query.where.add(query.columns.flag.le(2))lt(value)
Compare column with a value or another column. Operator: lessThan
Parameters
Object value ;
Returns: QBCondition a QBCondition representing the "less than" comparison.
