DbFunctionParameterBuilder(IMutableDbFunctionParameter)

This is an internal API that supports the Entity Framework Core infrastructure and not subject to the same compatibility standards as public APIs. It may be changed or removed without notice in any release. You should only use it directly in your code with extreme caution and knowing that doing so can result in application failures when updating to a new Entity Framework Core release.

public DbFunctionParameterBuilder(IMutableDbFunctionParameter parameter)

Parameters

parameter IMutableDbFunctionParameter

Properties

Metadata

The function parameter metadata that is being built.

public virtual IMutableDbFunctionParameter Metadata { get; }

Property Value

IMutableDbFunctionParameter

Methods

HasStoreType(string)

Sets the store type of the function parameter in the database.

public virtual DbFunctionParameterBuilder HasStoreType(string storeType)

Parameters

storeType string

The store type of the function parameter in the database.

Returns

DbFunctionParameterBuilder

The same builder instance so that further configuration calls can be chained.

PropagatesNullability(bool)

Indicates whether parameter propagates nullability, meaning if it's value is null the database function itself returns null.

public virtual DbFunctionParameterBuilder PropagatesNullability(bool propagatesNullability = true)

Parameters

propagatesNullability bool

Value which indicates whether parameter propagates nullability.

Returns

DbFunctionParameterBuilder

The same builder instance so that further configuration calls can be chained.
