Primary keys By convention, non-composite primary keys of type short, int, long, or Guid are set up to have values generated for inserted entities if a value isn't provided by the application. You can create computed columns in your database tables. In the EF model you just annotate the corresponding properties with the DatabaseGenerated attribute: [DatabaseGenerated(DatabaseGeneratedOption.Computed)] public double Summ { get; private set; } The reason of the problem was a bug in the Effort database. When the computed column is based on non-nullable columns, the computed column would also automatically become non-nullable. Therefor, the Effort database was expecting a non-null value. With the latest update the problem is resolved. 2017-09-09 Do an update-database in the PM and it should add the computed column properly.

You cannot have a persisted computed column which references other tables. Probably because it would make it almost impossible to change the data - every time you inserted, updated, or deleted a row in any table, SQL Server would have to check every other table in the database to see if the persisted value needed to be updated.

Ef computed column

I say it because unless you really need a computed column, you could just as easily create a read-only property that EF ignores. However, in some cases, a computed column is a viable option such as when you need to sort (on the database-side) against a computed value. That was my own reason for using a computed. Manually adding the function and

Ef computed column

So, effectively, if you have a calculated column with UniqueName=" RejectedInvoices " , it will sort your data objects if you expose a public property named " RejectedInvoicesResult ". Entity Framework 6 with a Database Generated field is failing on insert. From what I've read once you mark a column as DatabaseGenerated, EF won't try to insert/update anything into that field, which is especially important in my case because the fields on the database are SQL Server computed columns and not just default values, which is what I've seen in a lot of similar questions on Stack Data Annotations - Column Attribute in EF 6 & EF Core. The Column attribute can be applied to one or more properties in an entity class to configure the corresponding column name, data type and order in a database table.

The Column attribute overrides the default convention. 2019-07-08 · Computed columns actually are virtual columns that are not physically stored in the table unless the column is marked PERSISTED.

If you're mapping your Code First classes to tables that contain computed columns, you don't want Entity Framework to try to update those columns. But you do want EF to return those values from the database after you've inserted or updated data. The Entity Framework Core Fluent API HasComputedColumnSql method is used to specify that the property should map to a computed column. The method takes a string indicating the expression used to generate the default value for a database column. In the following example, the LastModified property of the Contact entity is mapped to a computed column.

With the latest update the problem is resolved. Unfortunatly, these computed properties don't work with Entity Framework out of the box. In this post I'm going to discuss the problem and suggest various ways of mitigating it. For example, consider the following entities that I will use as an example throughout this post.

Trying to use a Computed column in my query but it seems EF Core handles it like any other column and just ignores the mapping. Is there somehting i do wrong here? or do i misunderstand the usage of the computed column :S This is almost the same examples as the documentation are using. EF … This article uses EF 7.0.0-rc1 which is the latest pre-release available on NuGet.org. You can find nightly builds of the EF7 code base hosted on https: A computed column can use other columns in the table to calculate its value. You can use Computed columns in SQL and configure them using Entity framework.
