Methods

ConfigureParameter(DbParameter)

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.

protected override void ConfigureParameter(DbParameter parameter)

Parameters

parameter DbParameter

GenerateEmbeddedNonNullSqlLiteral(object)

Generates the SQL representation of a non-null literal value, meant to be embedded in another literal value, e.g. in a range.

protected virtual string GenerateEmbeddedNonNullSqlLiteral(object value)

Parameters

value object

The literal value.

Returns

string

The generated string.

GenerateEmbeddedProviderValueSqlLiteral(object?)

Generates the SQL representation of a literal value without conversion, meant to be embedded in another literal value, e.g. in a range.

public virtual string GenerateEmbeddedProviderValueSqlLiteral(object? value)

Parameters

value object

The literal value.

Returns

string

The generated string.

GenerateEmbeddedSqlLiteral(object?)

Generates the SQL representation of a literal value meant to be embedded in another literal value, e.g. in a range.

public virtual string GenerateEmbeddedSqlLiteral(object? value)

Parameters
