如何解決錯誤：無法執行INSERT INTO saveanswer（answer）VALUES（'d'）。現場「sanswer」沒有默認值

Question

ERROR: Could not able to execute INSERT INTO saveanswer (answer) VALUES ('d'). Field 'sanswer' doesn't have a default value

Answer 1

一種選擇將是這樣的查詢來指定該字段的值：

INSERT INTO saveanswer (answer, sanswer) VALUES ('d', 'something here') 

其他的解決方案將是改變你的表格設置該字段的默認值（null或其他）如下：

ALTER TABLE saveanswer ALTER COLUMN sanswer SET DEFAULT null;
