264—Appendix B. Command Reference

Follow the db command by the name of the database to be opened or to be created (if it does not already exist). You may include a path name to work with a database not in the default path.

You may use the “as” keyword to provide an optional shorthand_name or short text label which may be used to refer to the database in commands and programs. If you leave this field blank, a default shorthand_name will be assigned automatically. See “Database Shorthands” on page 263 of the User’s Guide for additional discussion.

Options

See dbopen (p. 266) for a list of available options for working with foreign format databases.

Examples

db findat

opens the database FINDAT in the default path and makes it the default database from which to store and fetch objects. If the database FINDAT does not already exist, an empty database named FINDAT will be created and opened.

Follow the dbopen keyword with the name of a database. You should include a path name to open a database not in the default path. The opened database will become the default database.

You may use the “as” keyword to provide an optional shorthand_name or a short text label which is used to refer to the open database in commands and programs. If you leave this field blank, a default shorthand_name will be assigned automatically. See “Database Shorthands” on page 263 of the User’s Guide for additional discussion.

By default, EViews will use the extension of the database file to determine type. For example, files with the extension “.EDB” will be opened as an EViews database, while files with the extension “.IN7” will be opened as a GiveWin database. You may use options to specify an explicit type.

dbpack—267

Options

type=arg, t=arg Specify the database type: AREMOS-TSD (“a”, “aremos”, “tsd”), DRIBase (“b”, “dribase”), EViews (“e”, “evdb”), FAME (“f”, “fame”), GiveWin/PcGive (“g”, “give”), Haver Analytics (“h”, “haver”), Rats Portable/ Troll (“l”, “trl”), RATS 4.x (“r”, “rats”), TSP portable (“t”, “tsp”), EcoWin (“ecowin”).

The following options may be required when connecting to a remote server:

Examples

dbopen c:\data\us1

opens a database named US1 in the C:\DATA directory. The command:

dbopen us1

opens a database in the default path. If the specified database does not exist, EViews will issue an error message. You should use db (p. 263) or dbcreate (p. 265) to create a new database.
