DBVALUEKINDENUM enumeration (cmdtree.h)

The DBVALUEKINDENUM enumerated type is used to indicate the type of the union member inside a DBCOMMANDTREE structure. For programming convenience, the values in this enumeration correspond exactly to the OLE Automation VARENUM and OLE DB DBTYPE enumerations. The comments associated with each enumeration value represent the type and branch of the union type inside the command structure containing the value. nodes that do not assign a value to the union member should assign a DBVALUEKIND_EMPTY to the wKind member of the DBCOMMANDTREE structure.
