Description

The DB_DATADIR environment variable is used to define the default data directory. Databases in Recital are implemented as directories containing files that correspond to the tables and associated files in the database. Operating System file protection can be applied individually to the files for added security. The directory is a sub-directory of the Recital data directory as set in DB_DATADIR. Databases are created using the SQL CREATE DATABASE command.

The dbexec utility is used to run program files via the Recital Database and Mirage Servers without connecting from a client. If DB_DATADIR is set to a directory, this directory will be added to the search path and is equivalent to using the SET PATH command.

Example

// create_dat.prg
CREATE DATABASE hr;
USE hr;
// end of create_dat.prg
> ? getenv([DB_DATADIR])
/opt/recital/data
> do create_dat
> ? default()
/opt/recital/data/hr
