Javascript 添加knex.js.andWhere()为条件为真
我有一个疑问:Javascript 添加knex.js.andWhere()为条件为真,javascript,node.js,knex.js,Javascript,Node.js,Knex.js,我有一个疑问: const customerProducts = db.sequelize.knex.select([ 'CustomerProduct.id AS _id', 'CustomerProduct.last_delivered AS _lastDelivered', 'CustomerProduct.margin AS _margin', 'CustomerProduct.outlier AS _outlier', 'Cu
const customerProducts = db.sequelize.knex.select([
'CustomerProduct.id AS _id',
'CustomerProduct.last_delivered AS _lastDelivered',
'CustomerProduct.margin AS _margin',
'CustomerProduct.outlier AS _outlier',
'CustomerProduct.growth AS _growth',
'CustomerProduct.period AS _period',
'CustomerProduct.price AS _price',
'CustomerProduct.active AS _active',
'CustomerProduct.customer_id AS _customerId',
'CustomerProduct.product_id AS _productId',
'CustomerProduct.modified AS _modified',
'CustomerProduct.month_value AS _monthValue',
'customer.id AS _customer_id',
'customer.title AS _customer_title',
'customer.code AS _customer_code',
])
.from('customer_products AS CustomerProduct')
.innerJoin(
'customers AS customer',
'CustomerProduct.customer_id',
'customer.id',
)
.where(whereClause)
.limit(limit)
.offset(offset);
我想包括一个.andWhere()
选项,该选项仅在满足此条件时才会添加到查询中:
if (overdue === 'true')
我该怎么做?您可以这样做:
const query = db.sequelize.knex.select([
'CustomerProduct.id AS _id',
'CustomerProduct.last_delivered AS _lastDelivered',
'CustomerProduct.margin AS _margin',
'CustomerProduct.outlier AS _outlier',
'CustomerProduct.growth AS _growth',
'CustomerProduct.period AS _period',
'CustomerProduct.price AS _price',
'CustomerProduct.active AS _active',
'CustomerProduct.customer_id AS _customerId',
'CustomerProduct.product_id AS _productId',
'CustomerProduct.modified AS _modified',
'CustomerProduct.month_value AS _monthValue',
'customer.id AS _customer_id',
'customer.title AS _customer_title',
'customer.code AS _customer_code',
])
.from('customer_products AS CustomerProduct')
.innerJoin(
'customers AS customer',
'CustomerProduct.customer_id',
'customer.id',
);
if (overdue === 'true') {
query = query.where(whereClause)
}
const customerProducts = query.limit(limit).offset(offset);
实际上我已经厌倦了,但是得到了
uncaughtException:await仅在异步函数中有效。你知道为什么吗?@runnerpaul你在一个未声明为async
的函数中使用await
(例如:async function something(){….}
)。
