MS Access - recordset not updateable on subform

Question

I have an ms database that uses a tsql backend - in this subform it creates a row in the table no problem but I can't add any text to the text field in the form- Access displays 'Recordset not updateable'. I can manually change data in the linked table and I can also delete rows, but once in the form I can not delete as it is saying the database is 'read only' ? Any help is much appreciated.

Answer 1

在设计视图下，查看表单的“数据”属性，确保“允许添加/编辑”选项为“是”。

Answer 2

错误归结为未在链接表上删除主键。
