我有一个表单，该表单从mysqli查询中接受php变量，然后在输入字段中显示。我得到的错误是... “错误：SQLSTATE [23000]：违反完整性约束：1048列'profileid'不能为空”，但该列也不为空。我检查了数据库，唯一的空列是id。它工作得很好，只是停了下来。我能够为profileid加载数据，所以我不确定为什么它说不为null时不能为null。我在这里看过其他几篇文章，但是还无法解决。请帮忙！

$selectquery = $con->prepare("SELECT adminlogin.nickname FROM adminlogin LEFT JOIN coinsub ON coinsub.profileid=adminlogin.profileid");
