[zeromicro/go-zero]字段可为空时查询抛异常

数据库中有个字段upLvTime，可为空:

upLvTime datetime(0) NULL DEFAULT NULL,

生成的model

UpLvTime time.Time db:"upLvTime"

查询抛异常：

sql: Scan error on column index 19, name "upLvTime": unsupported Scan, storing driver.Value type into type *time.Time

当前查询到的记录中upLvTime字段为null

请问这个问题怎么解决呀？
