Summary

 

 

 

 

 

RUN [ stmt_num ]

 

Displays and executes the current statement or specified state-

 

 

 

ment in the history buffer. See Section 3.7.16 "RUN" on page 3-

 

 

 

33 details.

 

 

 

 

 

LIST [ stmt_num ]

 

Displays the current statement or specified statement in the his-

 

 

 

tory buffer, and makes that statement the current statement by

 

 

 

copying it to the end of the history list. See Section 3.7.14 "LIST"

 

 

 

on page 3-32 for details.

 

 

 

 

 

EDIT [ stmt_num ]

 

Edits the current statement or specified statement in the history

 

 

 

buffer, and makes the edited statement the current statement by

 

 

 

copying it to the end of the history list. The environment variable

 

 

 

EDITOR can be set to the editor of choice. See Section 3.7.8

 

 

 

"EDIT" on page 3-25 for details.

 

 

 

 

 

SAVE filename

 

Saves the current statement in the history buffer to the specified

 

 

 

file, which can then be retrieved through the GET or START

 

 

 

statements. See Section 3.7.17 "SAVE" on page 3-34 for details.

 

 

 

 

 

GET filename

 

Fetches the contents of the specified file, from the beginning of

 

 

 

the file to the first semicolon, and appends it to the history buffer.

 

 

 

The statement fetched by the GET can then be executed by

 

 

 

using the RUN statement. See Section 3.7.10 "GET" on page 3-

 

 

 

27 for details.

 

 

 

 

 

START filename

[

argument … ]

 

Unlike the GET statement, START executes the statement and

 

 

 

accepts arguments that it substitutes for parameter references in

 

 

 

the statement stored in the file. START also appends the state-

 

 

 

ment to the history buffer. See Section 3.7.21 "START" on page

3.4FORMATTING OUTPUT OF ISQL QUERIES

Formatting of database query results makes the output of a database query more presentable and understandable. The formatted output of an ISQL database query can be either displayed on the screen, written to a file, or spooled to a printer to produce a hardcopy of the report.
