下面的裸值命令为我在PostgreSQL工作:

VALUES (1,2,3), (4,5,6), (7,8,9)

在Oracle SQL中，您可以使用JSON_TABLE从JSON创建表:

SELECT
   t.emp_name,
   t.emp_age
FROM
   JSON_TABLE (
   '{
     "employees": [{name:"Alice", age: 19}, {name: "Bob", age: 23}]
  }',
  '$'
  COLUMNS (
     NESTED PATH '$.employees[*]'
     COLUMNS (
        emp_name VARCHAR2(50) PATH '$.name',
        emp_age NUMBER(3,0) PATH '$.age'
     )
  )
) t;

SELECT * 
FROM DUAL 
CONNECT BY ROWNUM <= 9;

Oracle。 感谢这篇文章PL/SQL -在Where in子句中使用“List”变量

我把我的示例语句放在一起，以便轻松地手动输入值(测试人员在测试应用程序时重用):

WITH prods AS (
    SELECT column_value AS prods_code 
    FROM TABLE(
        sys.odcivarchar2list(
            'prod1', 
            'prod2'
        )
    )
)
SELECT * FROM prods

DB2的一个选项:

SELECT 101 AS C1, 102 AS C2 FROM SYSIBM.SYSDUMMY1 UNION ALL
SELECT 201 AS C1, 202 AS C2 FROM SYSIBM.SYSDUMMY1 UNION ALL
SELECT 301 AS C1, 302 AS C2 FROM SYSIBM.SYSDUMMY1
