How to parse current time to InfluxDB Go client?
问题
我正在使用以下Go客户端（"github.com/influxdata/influxdb/client/v2"）查询InfluxDB，并且它工作正常。
q = fmt.Sprintf("SELECT * FROM %s WHERE time > now() - 3600s", Measurement)
但是我想使用Go的时间变量代替InfluxDB的now()。
t := time.Now().Format(time.RFC3339)
q = fmt.Sprintf("SELECT * FROM %s WHERE time > %s - 3600s", Measurement, t)
但是出现了错误解析查询：在第1行，第101个字符处找到-01，预期为;。
英文:
I am using below Go client ("github.com/influxdata/influxdb/client/v2") to query InfluDB and it is working fine
q = fmt.Sprintf("SELECT * FROM %s WHERE time > now() - 3600s", Measurement)
but I want to use Go time variable instead of InfluxDB now()
t := time.Now().Format(time.RFC3339)
q = fmt.Sprintf("SELECT * FROM %s WHERE time > %s - 3600s", Measurement, t)
but getting error parsing query: found -01, expected ; at line 1, char 101

日期字符串必须使用单引号括起来。使用以下代码可以解决你的问题：
t := time.Now().Format(time.RFC3339)
q = fmt.Sprintf("SELECT * FROM %s WHERE time > '%s' - 3600s", Measurement, t)
英文:
Date strings must be single quoted. Using
t := time.Now().Format(time.RFC3339)
q = fmt.Sprintf("SELECT * FROM %s WHERE time > '%s' - 3600s", Measurement, t)
Should solve your issue.
