我必须更改查询，并希望在两个不同的列上找到两个值时向查询添加一些预定义的结果（输出）。
基本上我想在查询的新列中添加值。我尝试使用CASE但直到现在都没有运气。
SELECT DISTINCT
Q1.SCHD_ID,
Q1.SCHD_DESC,
Q1.TIMEZONE_ID,
Q1.DISPLAY_IN_SCHD_TZ,
Q1.LOGO_ID,
Q1.CODICE_SKOFF,
Q1.CODICE_MODULO,
case
when (Q1.PIANO_CODICE = 'FND001' AND Q1.CODICE_SKOFF = '2346') THEN 'testA'
WHEN (Q1.PIANO_CODICE = 'FND001' AND Q1.CODICE_SKOFF = '2347') THEN 'testB'
WHEN (Q1.PIANO_CODICE = 'FND001' AND Q1.CODICE_SKOFF = '3287') THEN 'testC'
WHEN (Q1.PIANO_CODICE = 'FND001' AND Q1.CODICE_SKOFF = '0000') THEN 'testD'
WHEN (Q1.PIANO_CODICE = 'TEST' AND Q1.CODICE_SKOFF = '4435') THEN 'testE'
ELSE 'NULL'

哪种方法最好？
dbms IS birt 我对查询的临时表有用吗？
谢谢
