我有具有票务状态的票务系统。我想做sequelize查询，将返回各自的状态计数。下面是可以正常工作的原始查询，我想将其转换为续集。
invoice_count我尝试了let querydata = `SELECT count(*) as total,
sum(case when status = 'Allocated' then 1 else 0 end) as allocated,
sum(case when status = 'RemindMe' then 1 else 0 end) as remindme,
sum(case when status = 'Close' then 1 else 0 end) as closed
FROM ticketnotifications
WHERE createdby = '` + req.auth.credentials.email + `';`;
return ticketdb.sequelize.query(querydata, { type: Sequelize.QueryTypes.SELECT })
.then((agentCountResult) => {
return res(agentCountResult[0]);
}).catch((err) => {
logger.error('agentCount exception...', err);
return res(boom.expectationFailed(err));
});
及其工作原理，但是我一直坚持如何在[Sequelize.fn('COUNT', Sequelize.col('id')), 'total']语句上方进行后续转换。有想法吗？
