Properties

	Name	Description
	TargetDatabaseType	Gets target DatabaseType for using escaped name.
	TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)
	UseAnsiQuotes	Gets or sets flag that determines if double quotes should be used as the identifier delimiter, per SQL-99 standard, regardless of database type. Defaults to true except for MySQL.

	GetHashCode	Returns the hash code for this instance. (Inherited from Attribute)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	IsDefaultAttribute	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)

Remarks

Applying [UseEscapedName] to a modeled table or field with no parameters will specify that an escaped name be used for all database types. Using a specific database type as a parameter to the attribute, e.g., [UseEscapedName(DatabaseType.SQLServer)], means the escaped name will only be applied to the specific database - however, the attribute allows multiple instances on the same identifier so you could specify that escaping only be applied to two databases, for example: [UseEscapedName(DatabaseType.SQLServer), UseEscapedName(DatabaseType.MySQL)]. In the event multiple attributes have been applied to a modeled identifier where one instance has specified no target database type and others have, the system will assume to target all databases for escaping the name and ignore the specific targets.
