使用多行透视 BigQuery 表

问题描述

为了透视我的大查询表，我找到了这段代码

SELECT 'SELECT id,' || 
   STRING_AGG(
      'MAX(IF(key = "' || key || '",value,NULL)) as `' || key || '`'
   ) 
   || ' FROM `project.dataset.table` GROUP BY id ORDER BY id'
FROM (
  SELECT key 
  FROM `project.dataset.table`
  GROUP BY key
  ORDER BY key

但即使我应用 EXECUTE IMMEDIATE 函数，它也会返回上面代码的字符串。 我在那个函数中遗漏了什么？

感谢您的帮助

解决方法

在下面使用

EXECUTE IMMEDIATE(
SELECT 'SELECT id,' || 
   STRING_AGG(
      'MAX(IF(key = "' || key || '",value,NULL)) as `' || key || '`'
   ) 
   || ' FROM `project.dataset.table` GROUP BY id ORDER BY id'
FROM (
  SELECT key 
  FROM `project.dataset.table`
  GROUP BY key
  ORDER BY key
)  
);
