Description

Flags used by TDBXValueType.

These flags provide information about a TDBXValueType instance. The TDBXValueType.GetFlags method returns a bit mask of these flags logically ORed together.

This table shows the flag constants.

Constant	Description
Nullable	Value is nullable
ReadOnly	Value is read only
Searchable	Value is searchable
AutoIncrement	Value is autoincrement
ReadOnlyType	Value type is read only
Hidden	Value type is hidden
ExtendedType	Used internally to indicate that most recent value types should be used if applicable. Only used by the most up to date driver implementations since use of these types breaks old interfaces.
ValueParameter	Used internally to mark a server method in out parameter as being a descendant of TDBXWritableValue. These are nullable parameters, regardless of their type.
Literal	Used to mark a parameter as being specified in the command text property as a literal value.
