轉換字符串數組爲整數

Question

的陣列我有以下SQL：

SELECT * FROM (SELECT t.id, t.summary, null as worker, tt.worked from ticket t 
INNER JOIN (SELECT ticket, sum(seconds_worked)/3600.0 as worked FROM ticket_time GROUP BY ticket) tt ON tt.ticket=t.id 
UNION ALL 
SELECT ticket,null, tt.worker, sum(tt.seconds_worked)/3600.0 from ticket_time tt GROUP BY ticket,worker) as foo 
WHERE id in ('9755, 9759') ORDER BY id 

在最後一行每當SQL執行能夠而且將會改變的ID字符串'9755, 9759'。 我能刺痛轉換爲一個這樣的數組：

string_to_array('9755, 9759', ',') 

但是，有沒有辦法這個字符串數組轉換成整數數組？

Answer 1

結果數組只投給int[]

where id = ANY (string_to_array('9755, 9759', ',')::int[])
