python sdk query_job.result() 无法轮询作业状态

Question

google-cloud-bigquery 版本是 1.5.0，堆栈在 sdk 代码中崩溃。有什么解决方法吗？

Answer 1

这表示您的查询中存在错误，而不是客户端代码中的错误。错误是：无法返回相对于 Unix 纪元 1534808046936000000 微秒的无效时间戳值。有效时间戳值范围为 [0001-01-1 00:00:00, 9999-12-31 23:59:59.999999]；写入字段 request_started_at 时出错听起来您有一个命名的字段/列的request_started_at比例不正确；1534808046936000000应该是1534808046936000。在迁移到标准 SQL的指南中有一些与此相关的材料。如果此列的所有值都未正确缩放，那么您可以执行以下操作来修复它们：CREATE OR REPLACE dataset.table ASSELECT *  REPLACE (TIMESTAMP_MICROS(DIV(UNIX_MICROS(request_started_at), 1000)) AS request_started_at)FROM dataset.table这将在将列中的值缩小 1000 倍后替换它们。
