Question

我正在运行以下命令：

#standardSQL
  UPDATE `speedy-emissary-167213.pgp_orielresearch.pgp_PIK3CA_all_features_values_step_5` AS t2 
 SET 
  chr3_3308581_TGGGGT=IF(t1.PIK3CA_features="chr3_3308581_TGGGGT",1,0),
  chr3_3294651_CA=IF(t1.PIK3CA_features="chr3_3294651_CA",1,0),
  chr3_3300867_CC=IF(t1.PIK3CA_features="chr3_3300867_CC",1,0),
  chr3_3308373_ACTTGACTTG=IF(t1.PIK3CA_features="chr3_3308373_ACTTGACTTG",1,0),
  chr3_3309125__T=IF(t1.PIK3CA_features="chr3_3309125__T",1,0),
......
  chr3_3300985_TT=IF(t1.PIK3CA_features="chr3_3300985_TT",1,0),
  chr3_3308139_AC=IF(t1.PIK3CA_features="chr3_3308139_AC",1,0)
FROM
  `speedy-emissary-167213.pgp_orielresearch.pgp_PIK3CA_all_features_values_step_4_sorted_500` AS t1
WHERE
  t1.sample_id = t2.sample_id

当我用500“chr3_3308581_TGGGGT = IF（t1.PIK3CA_features =”chr3_3308581_TGGGGT“，1,0）运行它时，”对于不同的列，Scalar子查询产生了多个元素被触发。当我使用less命令（通过删除部分命令）运行它时，命令成功运行。调试此查询的最简单方法是什么？

谢谢！

在where子句中缺少另一个条件。这工作

#standardSQL
UPDATE
  `speedy-emissary-167213.pgp_orielresearch.pgp_PIK3CA_all_features_values_step_5` AS t2
SET
  chr3_3294687_A = 1
FROM
  `speedy-emissary-167213.pgp_orielresearch.pgp_PIK3CA_all_features_values_step_4_sorted_500` AS t1
WHERE
  t1.sample_id = t2.sample_id and t1.PIK3CA_features="chr3_3294687_A"

BigQuery，SQL更新命令，错误：标量子查询生成多个元素
