This blog gathers together all you need to install SQLcl (Open-Source Liquibase 4.18.0 is included, no need for a separate installation), configure it and use it with your Oracle databases - both on-premise and OCI Cloud (ATP, ADW, etc.). MacOS & Windows guide included.

For a standalone Liquibase installation guide, see my other article.

Installation steps for macOS

tested at MacbokPro with M1 Sonoma 14.2.1
SQLcl 23.3 with Open Source Liquibase 4.18.0 included

Go to the Oracle website and download the latest version of SQLcl.

Unpack the downloaded file and put it in your folder with applications.

I use /Users/rg/apps/oracle/ for that (use whatever you wish)
Your folder /sqlcl/ should look similar to this:

Your macOS should already have JAVA installed, but verify it by typing into the terminal:

java --version

If you don't have JAVA, install it first.

Add SQLcl to your path:

Most Macs use ZSH (Z Shell - default for MacOS and Linux)
Go to /your_user/ and find .zshrc file
If you don't see it, you must make your hidden files visible by clicking "SHIFT+CMD + ."

Read this article if you can't find zshrc.

Add new line (change it for your path)

 export PATH="/Users/[your_user]/apps/oracle/sqlcl/bin:$PATH"
# change the path if you use different folder

Save the file and verify if SQLcl is installed.

Open terminal and type:

sql /nolog

Enjoy your SQLcl installation!

Installation steps for Windows

tested with Windows 11
SQLcl 23.3 with Open Source Liquibase 4.18.0 included

Go to the Oracle website and download the latest version of SQLcl.

Unpack the downloaded file and put it in your folder with applications.

I use C:\Users\rgrze\tools\sqlcl-latest for that (use whatever you wish)
Your folder \ sqlcl \ should look similar to this:

Configure your PATH. To do this, go to environment variables.

Ensure you have JAVA_HOME defined.

Go to "Path" and click on first Edit button below it.

Add new PATH.

Select a location of your \sqlcl\bin folder

Verify installation by opening the terminal and typing:

All set.

SQLcl configuration for usage with Oracle databases: on-prem & cloud

Below instructions are the same for MacOS & Windows users

Oracle Cloud Autonomous Database (ATP, ADW) using Oracle Wallet

log into your OCI account and download your instance or regional wallet
save it in your chosen location
I use /Users/rg/apps/oracle/wallets/privs for that
It looks like this:
- open terminal and SQLcl ( nolog = open SQLcl without connection)
  
  type sql /nolog
```
  sql /nolog
```
- Set the location of the wallet.
  
  macOS:
```
  set cloudconfig /users/rg/apps/oracle/wallets/priv/Wallet_REGIONAL.zip
```

Windows:

          set cloudconfig C:\Users\rgrze\tools\wallets\Wallet_DEV.zip

type show tns*t*o list available entries
```
          show tns
```
type connect username@[TNS_NAME] to connect to your database (you will be prompted for password)
You can also type connect username/password@[TNS_NAME]
you can type**show connection - to see your current connection

An alternative way of connecting (right after you open your terminal) is:

sql username@TNS_NAME

--or
sql username/password@TNS_NAME

Oracle Database On-Premise ( no wallet)

Just type:

--provide password
sql username/password@host:port/SID

--will be prompted for password
sql RAFAL@127.0.0.1:1521/MYSID

--or
sql /nolog
connect RAFAL@127.0.0.1:1521/MYSID

Save your connection with a friendly name and connect with ease!

This is the easiest way of connecting, e.g. to my connection called COOL

This feature is called saved connections - read more about it here.

You can use it both with on-premise and cloud connections.

Use standalone Liquibase to deploy SQLcl changesets

If you want to use standalone Liquibase, you can still deploy changesets generated by Oracle SQLcl. To do this you need to do some simple tweaks. Just follow this quick tutorial from SQLcl documentation

How to install standalone Liquibase? Just read my step-by-step tutorial.

Configure Liquibase for UTF-8 encoding (Windows users)

Read this tutorial.

How to use SQLcl + Liquibase

Read my blog series "Mastering SQLcl Liquibase"
Oracle 23.3 official documentation is here
And if you are looking for fast examples, just open SQLcl and type help to list available commands
