JET_DBID
The JET_DBID data type contains the handle to the database. A database handle is used to manage the schema of a database. It can also be used to manage the tables inside of that database.
typedef unsigned long JET_DBID;
Data Types
JET_DBID
Handle to the database.
A value of JET_dbidNil indicates that the handle is invalid.
Remarks
A database handle is created by means of a call to JetCreateDatabase or JetOpenDatabase.
A database handle can be explicitly closed by JetCloseDatabase or implicitly closed by JetEndSession or JetTerm.
A database handle can be used only within the session in which it was created. The existence of a database handle corresponds to the logical open of a database. A logical open is different from the physical open of a database, which happens when a database is attached to the system.
