有没有办法让这项工作?
SELECT
*
FROM table t
INNER JOIN othertable t2 USING (tid)
WHERE
t.tid =
CASE
WHEN t2.someboolval THEN ANY(ARRAY[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16])
ELSE ANY(ARRAY[77,66])
END
不幸的是我不能只做t.tid = CASE WHEN t2.someboolval THEN 1 ELSE 2 END
,因为我需要匹配一个数组。这可行吗?

使用AND / OR。类似的东西:
SELECT
*
FROM table t
INNER JOIN othertable t2 USING (tid)
WHERE
t2.someboolval AND t.tid IN (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16)
OR NOT (t2.someboolval) and t.id IN (77,66)

你必须改变任何地方:
SELECT
*
FROM table t
INNER JOIN othertable t2 USING (tid)
WHERE
t.tid =
ANY(CASE
WHEN t2.someboolval THEN ARRAY[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16]
ELSE ARRAY[77,66]
END)
