SELECT_QUERY = `SELECT * FROM events WHERE c_id = ? AND start_time > ? and
end_time < ?`
query := sr.db.Raw(SELECT_QUERY, request.GetCId(), startTime, endTime)
var v = request.GetVIds()
if len(v) > 0 {
query = query.Where(` v_id IN (?) `, v)
} //Only this block introduces first ) after end_time
var c = request.GetStatus().String()
if len(c) > 0 {
query = query.Where( " status = ? ", c) // this introduces the other opening brace //after AND
}
以下是生成并在日志中找到的查询
SELECT * FROM events WHERE c_id = 1 AND start_time > '2020-04-16 18:42:00' and
end_time < '2020-04-16 18:45:50' ) AND ( v_id IN (1,2)) AND ( status = 'STATUS_MIDDLE_CLASS' ORDER BY start_time DESC LIMIT 5 OFFSET 1
stackoverflow和Internet文章中的其他解决方案没有帮助。
PS:是因为我混合了db.Raw()和query.Where()吗?
最佳答案
改变了吗?至$ 1不能解决问题。
基本上有几件事解决了这个问题。
1)混合Raw
和query.Where
是一个问题。
在对Raw
进行查询之后
2)
SELECT_QUERY = `SELECT * FROM events WHERE c_id = ? AND start_time > ? and
end_time < ?`
已经有
sr.db.Where
。然后使用select * from
引入嵌套的query := sr.db.Raw(SELECT_QUERY, request.GetCId(), startTime, endTime)
因此,如下更改SELECT_QUERY
SELECT_QUERY = `events WHERE c_id = ? AND start_time > ? and
end_time < ?`
解决了这个问题。
