RelationalSqlGenerationHelper Class

Definition

Provides services to help with generation of SQL commands.

This type is typically used by database providers (and other extensions). It is generally not used in application code.

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.
