Description
The LIST DATABASE command is used to display information about the currently active database.
Databases are opened using the OPEN DATABASE command.
The LIST DATABASE command displays the following information:
- Database Name, e.g. southwind
- Database Path, e.g. /usr/recital/data/southwind
and for each table in the database the equivalent of LIST STRUCTURE INDEX followed by LIST DICTIONARY:
- Table file name
- Number of records
- Date of creation
- Date of last update
- Encryption status
- Field names, types, sizes and description
- Total record length
- Production DBX file name
- Index tag names, keys, types and lengths
- Dictionary information
| Keyword | Description |
|---|---|
| TO <file> | The display output will be sent to the specified file. The filename can be substituted with a <expC>, enclosed in round brackets, which returns a valid filename. If no file extension is specified, then ".txt" will be used. The command SET PAGELENGTH governs the output file pagination and SET PAGEWIDTH defines the width of each page. Page numbers are centered on the bottom of the page according to width. |
| TO PRINT | The display output will be sent to a printer. The TO PRINT option will default to a local printer unless the command SET PRINTER TO \\SPOOLER is issued. The print request will then be spooled to the system printer, which is defined by the environment variable DB_PRINT. |
Example
