sql - DB2 11 query with anonymous table or hard list of values

Question

I'd like a DB2 compatible query for all the values in my own hardcoded list of values that are NOT in a table. This query works well in Microsoft SQL Server

SELECT * FROM
  (values (1),(2),(3),(4),(7), (7000000)) as T(ID)
EXCEPT
  SELECT ID
  FROM ACCOUNT;

I'm aware of this answer SQL - How can I return the IDs from a where clause list that are not in the table? where they suggest using a VALUES clause. Perhaps it works with other versions of DB2, but on mine I get the error "Illegal symbol (" so I'm not sure it likes the VALUES function in my version of DB2.

Answer 1

Z/OS 的 Db2 v11 不支持此上下文中的 values 子句，尽管 Linux/Unix/Windows 上的 Db2 v11 确实支持它。

虽然它很丑，并且可能有更好的方法，但您可以尝试：

SELECT * FROM (select 1 from sysibm.sysdummy1 union select 2 from sysibm.sysdummy1 union select 3 from sysibm.sysdummy1 union select 4 from sysibm.sysdummy1 union select 7 from sysibm.sysdummy1 union select 7000000 from sysibm.sysdummy1 ) EXCEPT SELECT ID FROM ACCOUNT;

Answer 2

使用可以使用sysibm.sysdummy1：

SELECT t.id
FROM (SELECT 1 as ID FROM sysibm.sysdummy1 UNION ALL
      SELECT 2 FROM sysibm.sysdummy1 UNION ALL
      SELECT 3 FROM sysibm.sysdummy1 UNION ALL
      SELECT 4 FROM sysibm.sysdummy1 UNION ALL
      SELECT 7 FROM sysibm.sysdummy1
     ) as t
EXCEPT
  SELECT ID
  FROM ACCOUNT;
