isql -- Firebird Interactive SQL shell


isql [-a] [-cache number] [-database path] [-echo] [-input file] [-merge_stderr] [-noautocommit] [-nowarnings] [-output file] [-password string] [-page number] [-role string] [-s number] [-terminator string] [-user name] [-x] [-z]


isql is a program that allows the user to issue arbitrary SQL commands as well as exctacting the metadata.

isql in Debian is available under the isql-fb name due to filename conflict with an executable from another package.


isql can handle various command line options. Most options can be abbreviated. Below are given the shortest abbreviations as well as the full versions.
Extract DDL (Data definition language) statements necessary to re-create database's structure, triggers and other metadata. The "CREATE DATABASE" statement is in a comment. Statements are printed to standard output unless -output is used. See also -extract.
-c buffers
-cache number
Specify default size of the buffers to be used in database pages.
-d path
-database path
Specifies target database name when extracting the metadata with the -extract option.
Prints each statement before executing it.
Extracts DDL statements to recreate database metadata.

If no -database option is given, -extract behaves exactly as -a. If -database is given, the "CREATE DATABASE" statement is not commented and the database name is replaced with path.

-i file
-input file
Reads commands from file instead of standard input. Exits with commit after the last command.
