插入mysql时，列不能为NULL
我正在尝试从pr_users中检索与同一个表中的username列匹配的roleid。用户名字段实际上是该特定用户的电子邮件地址。有两个函数，一个是函数add_new_checklist，另一个是函数get_roleid，我将$ dbdata [＆＃39;责任＆＃39;]从else部分传递给函数get_roleid。我想从pr_users中检索userroleid，它与变量$ dbdata [＆＃39;责任＆＃39;]中的用户名列相匹配。我从else部分调用函数get_roleid 即$ role_id = $ this-＆gt; get_roleid（$ var）;并附上表格图片。
但是我收到了一个错误：
发生数据库错误
错误号码：1048
列＆＃39; roleid＆＃39;不能为空
INSERT INTO pr_exit_checklists（
action_item，category，responsibility，target_completion_period，target_completion_day，target_completion_from，status，roleid）价值观（＆＃39;新商品＆＃39;， ＆＃39;管理＆＃39;，＆＃39; shashankbhat11 @ gmail.com＆＃39;，＆＃39;＆＃39;，＆＃39; 5＆＃39;， ＆＃39;辞职日期＆＃39;，＆＃39; 1＆＃39;，NULL）

1 个答案:
答案 0 :(得分：0)
您不允许在pr_exit_checklists表中插入NULL，也不允许从您的查询中插入NULL。 您需要在表中启用allow NULL选项 或者您需要更改插入语句并将roleid传递为0或1。
