以下是BigQuery Standard SQL

#standardSQL
WITH table1 AS(
  SELECT "America" AS country_name UNION ALL
  SELECT "Germany" AS country_name UNION ALL
  SELECT "England" AS country_name UNION ALL
  SELECT "Nauru" AS country_name UNION ALL
  SELECT "Brunei" AS country_name UNION ALL
  SELECT "Kiribati" AS country_name UNION ALL
  SELECT "Djibouti" AS country_name UNION ALL
  SELECT "Malta" AS country_name
)
SELECT *
FROM table1
ORDER BY CASE 
  WHEN LOWER(SUBSTR(country_name, 1, 1)) IN ('a', 'g', 'e') 
  THEN CONCAT(' ', country_name) ELSE country_name 
END

预期产出

Row country_name     
1   America  
2   England  
3   Germany  
4   Brunei   
5   Djibouti     
6   Kiribati     
7   Malta    
8   Nauru

如果您只需要那些国家/地区

#standardSQL
WITH table1 AS(
  SELECT "America" AS country_name UNION ALL
  SELECT "Germany" AS country_name UNION ALL
  SELECT "England" AS country_name UNION ALL
  SELECT "Nauru" AS country_name UNION ALL
  SELECT "Brunei" AS country_name UNION ALL
  SELECT "Kiribati" AS country_name UNION ALL
  SELECT "Djibouti" AS country_name UNION ALL
  SELECT "Malta" AS country_name
)
SELECT *
FROM table1
WHERE LOWER(SUBSTR(country_name, 1, 1)) IN ('a', 'g', 'e')

或

#standardSQL
WITH table1 AS(
  SELECT "America" AS country_name UNION ALL
  SELECT "Germany" AS country_name UNION ALL
  SELECT "England" AS country_name UNION ALL
  SELECT "Nauru" AS country_name UNION ALL
  SELECT "Brunei" AS country_name UNION ALL
  SELECT "Kiribati" AS country_name UNION ALL
  SELECT "Djibouti" AS country_name UNION ALL
  SELECT "Malta" AS country_name
)
SELECT * 
FROM table1
WHERE REGEXP_CONTAINS(country_name, r'(?i)^(a|g|e)')

以上都返回：

Row country_name     
1   America  
2   Germany  
3   England
