Features

The irissqlcli is written using prompt_toolkit_.

• Auto-completes as you type for SQL keywords as well as tables and columns in the database.

• Syntax highlighting using Pygments.

• Smart-completion (enabled by default) will suggest context-sensitive completion.

  • SELECT * FROM <tab> will only show table names.
  • SELECT * FROM users WHERE <tab> will only show column names.

• Pretty prints tabular data.

Config

A config file is automatically created at ~/.config/irissqlcli/config at first launch. See the file itself for a description of all available options.

Docker

irisqlcli can be run from within Docker. This can be useful to try irissqlcli without installing it, or any dependencies, system-wide.

To create a container from the image:

$ docker run --rm -ti caretdev/irissqlcli irissqlcli <ARGS>

To access InterSystems IRIS databases listening on localhost, make sure to run the docker in "host net mode". E.g. to access a database called "foo" on the IRIS server running on localhost:1972 (the standard port):

$ docker run --rm -ti --net host caretdev/irissqlcli irissqlcli iris://_SYSTEM:SYS@localhost:1972/USER

or without `host net mode`

$ docker run --rm -ti caretdev/irissqlcli irissqlcli iris://_SYSTEM:[e-mail]:1972/USER

IPython

irisqlcli can be run from within IPython console. When working on a query, it may be useful to drop into a irissqlcli session without leaving the IPython console, iterate on a query, then quit irissqlcli to find the query results in your IPython workspace.

Assuming you have IPython installed:

$ pip install sqlalchemy~=1.4.0 ipython-sql sqlalchemy-iris

After that, run ipython and load the irissqlcli.magic extension:

$ ipython

In [1]: %load_ext irissqlcli.magic

or 
$ ipython --ext irissqlcli.magic

Connect to a database:

In [2]: %irissqlcli iris://_SYSTEM:SYS@localhost:1972/USER
self.dialect <class 'sqlalchemy_iris.iris.IRISDialect_iris'>
sqlalchemy.MetaData <class 'sqlalchemy.sql.schema.MetaData'>

Exit out of irissqlcli session with Ctrl + D and find the query results:

[SQL]_SYSTEM@localhost:USER>                                                                                                                                     
Goodbye!
Done.
