On the shell command line:
export DB_CLASS=[Pg|mysql|whatever] DB_USER=usename DB_PASSWORD=pwd
[$install-path/]generate dbname tablename > per-file-name.per
[$install-path/]perform per-file-name.per (or pps-file-name.pps)
Or in perl, with the above environment settings:
Emulates the Informix Perform character-terminal-based database query and update utility.
The filename given to the perform command may be a Perform specification (.per) file. The call to the run function may be a filename of a .per file or of a file pre-digested by the DBIx::Informix::Perform::DigestPer class (extension .pps). [Using pre-digested files does not appreciably speed things up, so this feature is not highly recommended.]
The argument to the run function may also be a string holding the contents of a .per or .pps file, or a hash ref with the contents of a .pps file (keys db, screen, tables, attrs).
The database named in the screen spec may be a DBI connect argument, or just a database name. In that case, the database type is taken from environment variable DB_CLASS. The username and password are taken from DB_USER and DB_PASSWORD, respectively.
Supports the following features of Informix's Perform:
Field Attributes: COLOR, NOENTRY, NOUPDATE, DEFAULT, UPSHIFT, DOWNSHIFT, INCLUDE, COMMENTS
2-table Master/Detail (though no query in detail mode)
VERY simple control blocks (nextfield= and let f1 = f2 op f3-or-constant) =head1 COMMANDS
The first letter of each item on the button menu can be pressed.
|Q = query. Enter values to match in fields to match. Field values|
|may start with >, >=, <, <=, contain val1:val2 or val1|val2|
|or end with * (for wildcard suffix). Value of the ``='' sign|
|matches a null value. The ESC key queries; DEL key aborts.|
A = add. Enter values for the row to add. ESC/DEL when done.
U = update. Edit row values. ESC/DEL when done.
R = remove. NO CONFIRMATION! BE CAREFUL USING THIS!
E = exit.
|M / D = Master / Detail screen when a MASTER OF relationship exists between|
Curses Curses::Application Curses::Forms Curses::Widgets
DBI and DBD::whatever
|DB_CLASS||this goes into the DBI connect string. NOTE: knows how|
|to prefix database names for Pg and mysql but not much else.|
DB_USER User name for DBI->connect.
|BGCOLOR||One of eight Curses-known colors for form background|
|(default value is 'black').|
|FIELDBGCOLOR||Default field background color (default is 'blue').|
|Fields' background colors may be individually overridden|
|by the ``color'' attribute of the field.|
Note, any field whose background matches the form background gets displayed with brackets around it: [field_here] .
