語法錯誤：預期輸入結束但在 BigQuery 中獲得了標識符

Question

SELECT

UPDATE
  `my-data-project12345-368309.cyclistic_jamesbimler.2022_Q1`
SET
  day_of_week =
    CASE
      WHEN day_of_week = '1' THEN 'Sunday'
      WHEN day_of_week = '2' THEN 'Monday'
      WHEN day_of_week = '3' THEN 'Tuesday'
      WHEN day_of_week = '4' THEN 'Wednesday'
      WHEN day_of_week = '5' THEN 'Thursday'
      WHEN day_of_week = '6' THEN 'Friday'
      WHEN day_of_week = '7' THEN 'Saturday'
    END

WHERE
    day_of_week IN ('1','2','3','4','5','6','7')

我正在嘗試將 day_of_week 列從 int 更改為字符串以表示星期幾，但我一直收到錯誤語法錯誤：輸入的預期結束但得到標識符

我曾嘗試移動代碼並刪除一些沒有運氣的東西。

試試這段代碼。 缺少分號的語法錯誤，已添加。

WHERE
