In the edmx file I deleted some of the properties because I don't want to add them to the POCO object, but each time I get that kind of exception:
Error 1 Error 3023: Problem in mapping fragments starting at line 255:Column COMPANY.contact_phone_number in table COMPANY must be mapped: It has no default value and is not nullable.
Why do I need map those columns if they don't have default values and are not nullable??
I get it.
I must map non-nullable fields without default value because when inserting there must be a value to the field!
我不确定我是否完全理解,您有一个POCO类,然后同一类在EDMX中也有定义,并且您要在POCO中指定某些属性,还是在EDMX中指定某些属性?
