为什么在Oracle APEX中会发生此错误？

[英]Why does this error happen in Oracle APEX?

原文 2018-02-16 01:21:38 5 1 sql/ oracle/ oracle-apex

I constantly get this " fieldname must have some value" error and I don't understand why it happens because I do enter all the values into the respective fields. 我经常收到此“ 字段名必须具有某些值”错误，并且我不明白为什么会发生这种情况，因为我确实将所有值输入相应的字段中。

I presume that 我认为

items' "Value required" property is set to YES, and/or 项目的“必需的值”属性设置为YES，和/或
there's a validation (automatically created by Apex because table column is set to be NOT NULL) 有一个验证（由Apex自动创建，因为表列设置为NOT NULL）

So, try to change that (just to see what happens): 因此，尝试更改它（只是看看会发生什么）：

set the "Value required" property to NO, 将“需要的值”属性设置为“否”，
set validation's "Condition" type to NEVER 将验证的“条件”类型设置为“从不”

Then run the page again. 然后再次运行页面。 If table columns are set to be NOT NULL, you'll get the error again, but this time not from Apex, but from the database. 如果表列设置为NOT NULL，您将再次收到错误，但这一次不是来自Apex，而是来自数据库。 Then you'll know that something really went wrong on your Apex page. 然后你就会知道的东西真的出了问题你的Apex页面上。
