database - PostgreSQL:WHERE id = ANY (idsArray) - 按 idsArray 排序结果

Question

在 Postgres 中使用 WHERE...ANY 样式查询以按给定数组对结果进行排序时，我是否遗漏了一个技巧？即:

SELECT *
FROM table
WHERE id = ANY (<idsInDesiredOrder>)

Answer 1

也许 array_position可以帮助您:

WITH sample (id, description) AS (
    VALUES 
        (1, 'lorem ipsum'),
        (2, 'lorem ipsum'),
        (3, 'lorem ipsum'),
        (4, 'lorem ipsum')
)
SELECT 
    * 
FROM 
    sample 
WHERE 
    id = ANY (ARRAY[3,2]) 
ORDER BY 
    array_position(ARRAY[3,2], id);
