A base class for the IUpdateSqlGenerator service that is typically inherited from by database providers. The implementation uses a separate SELECT query after the update SQL to retrieve any database-generated values or for concurrency checking.

This type is typically used by database providers; it is generally not used in application code.

public abstract class UpdateAndSelectSqlGenerator : Microsoft.EntityFrameworkCore.Update.UpdateSqlGenerator

type UpdateAndSelectSqlGenerator = class

Remarks

The service lifetime is Singleton. This means a single instance is used by many DbContext instances. The implementation must be thread-safe. This service cannot depend on services registered as Scoped.

See Implementation of database providers and extensions for more information and examples.

Constructors
