Description

TSQLDBParam is used to be able to create parameters which can store info about a field on which the parameter is based in the TSQLDBParam.FieldDef field. This is useful when constructing update or insert queries. It can also store private data needed for the various TSQLConnection descendents in the TSQLDBParam.SQLDBData property.
