SQL - 基本的SELECT语句

Question

我想在sql中创建这个结构（作为SELECT语句的结果）：

我正在尝试使用此查询：

SELECT "Name" AS School, (SELECT 20 AS "1", 50 AS "2", 90 AS "3") AS Age;

但它不起作用，错误：Operand should contain 1 column(s)。是否可以仅使用select语句创建这样的东西？

Answer 1

在SQL中无法使用格式，但这是可能的

SELECT 'Name' AS School, 20 AS `Age1`, 50 AS `Age2`, 90 AS `Age3`
