case when格式化问题

[BryceQin]

格式化前：
SELECT *
FROM t
WHERE
CASE WHEN comp_cd = '0593' THEN 'USD'
WHEN comp_cd = '0594' THEN 'USD'
WHEN comp_cd = '1601' THEN 'CNY'
WHEN comp_cd = '1602' THEN 'CNY' END = t.cy_cd
格式化后：
SELECT *
FROM t
WHERE CASE WHEN comp_cd = '0593' THEN 'USD' WHEN comp_cd = '0594' THEN 'USD' WHEN comp_cd = '1601' THEN 'CNY' WHEN comp_cd = '1602' THEN 'CNY' END = t.cy_cd
