ISQL and Tools

edited. When you exit the editor, ISQL writes the buffer contents as the last statement in the history buffer.

By default, ISQL invokes the vi editor on UNIX and the MS-DOS editor on NT. You can change the default by setting the EDITOR environment variable:

•On UNIX, set the environment variable at the operating system command level: setenv EDITOR /usr/local/bin/gmacs

•On NT, set the environment variable in the initialization file DHSQL.INI in the windows directory:

EDITOR = c:\msoffice\winword.exe

Examples

The following example uses the ! (shell) command to show the currently-set value of the EDI- TOR environment variable in the UNIX environment (it shows that it is set to invoke the GNU emacs editor). Then, the example uses the EDIT command to read in the fifth statement in the history buffer into an editing buffer.

ISQL> ! printenv EDITOR /usr/local/bin/gmacs ISQL> EDIT 5;

The following example edits the last statement in the history buffer: ISQL> select * from systable; -- bad table name!

*

error(-20005): Table/View/Synonym not found

ISQL> EDIT -- invoke an editor to correct the error

.

.

.

ISQL> list –- corrected statement is now the current statement: select * from systables

ISQL> run -- run the corrected statement
