Language Reference
LDBNAME Function
Returns the logical name of a database that is currently connected.
SYNTAX
integer-expression
The sequence number of a database the Progress session is connected to. For example, LDBNAME(1) returns information on the first database the Progress session is connected to, LDBNAME(2) returns information on the second database the Progress session is connected to, etc. If you specify a sequence number that does not correspond to a database the Progress session is connected to, the LDBNAME function returns the unknown value (?).
logical-name or alias
These forms of the LDBNAME function require a quoted character string or a character expression as a parameter. If the parameter is the logical name of a connected database or an alias of a connected database then the logical name is returned. Otherwise, Progress returns the unknown value (?).
BUFFER bufname
The name of a database table or buffer. The BUFFER option lets you determine the database a certain table belongs to without hard-coding the logical database name or alias.
EXAMPLEThis procedure disconnects all currently connected databases. After a database is disconnected, the connected databases are renumbered to reflect the change. For example, if databases 1, 2, 3, and 4, are connected and the procedure disconnects database 3, database 4 becomes database 3.
NOTE
To determine if a particular name is an ALIAS or a logical database name, use this following procedure.
