How to download and setup sqlplus for running sql commands? - oracle

Question

I am sorry, for bugging you all with a very silly question probably, but I just started learning data base management system, and today I attempted my first sql class where I had to login by providing my login details and learned some introductory syntax. But I already got my first sql assignment where I have to create a table and enter values. For that I need to downlad sql plus in my computer. I opened the Oracle website and got confused. Didn't understand how to do it,neither could find a good step by step instructions by which I can understand it and download. Please provide a step by step process with links by which I can download it properly. Also I would like to say, my school provided sql plus software but it isn't running and giving an error "ocl.dll" error. I really need your help. Thanks in advance.

Answer 1

If you need SQL*Plus you can download the Oracle Instant client from here
Install this and make sure you have the SQL*Plus exe on your path.
Alternatively you can also use Oracle SQLDeveloper from here or SQLcl which is a java based command line for Oracle SQL based on the SQL engine we built for SQLDeveloper. You can download it here.
SQLcl is very easy and you can connect to any Oracle database using EZconnect syntax
sql.exe usernamepassword#yourdatabasemachinename:yoursqlportnumber/databasename
e.g.,
sql barry/omagh#devbox:1521/DEVDB1
Any questions on these, take a look at the community pages here.
Hope this helps.

Answer 2

I felt adding sql server and installing took a lot to discover and understand so I am adding some steps to get the same usage that one can find using sql+ tool. This installation is for oracle 11g express edition.
This is the link from which you can download oracle database software.
extract the zip file (don't change the name)
Start the "Setup"
when asked to choose password choose something you
will not forget and write it down
because this can't be changed easily later
When it will be installed completely, you will
see a shortcut in desktop which in most of the cases doesn't work
Open your browser type this link
http://127.0.0.1:8080/apex/f?p=4950
Caution: this port number can be 8081 or something else with respect to your free ports. If its occupied then when installing a window will appear having a PORT number section, one can see the number there.
You will see an Oracle window, choose "Application Express"
when you see a prompt of login put SYSTEM as user name
and give the password you have chosen in 4th step
You will see another window "Create Application
Express Workspace"
Choose "Create New" as "Database Username"
Give a name to "Database Username" and that must be
same with the next "Application Express Username"
Password same as 4th
11.You will see a window again where you have to
give your password
Now you will see 4 options
choose "SQL Workshop"->"sql Commands"
You are all set and you can do everything here.
Otherwise CLIMAX: Go to search button of your pc
type "Run SQL Command Line". You will see the
Command Line Interface.
Type in the window after SQL>
CONNECT USERNAME/PASSWORD
(these credentials are what you created in 9th and 10th
step)
Now you are ready to do whatever you want.

I recently did this for Oracle 19c
Download SqlPlus instant client - instantclient-sqlplus-windows.zip
Download Instant Client - instantclient-basiclite-windows.x64-19.9.0.0.0dbru.zip
Extract files from step #2 into some folder, e.g. c:\Program Files\OraInstClient
Extract files from step #1 into the same folder
Add this folder to the PATH Environment Variable in your Windows system
Open CMD window and type sqlplus
To connect without tnsnames.ora use this syntax
C:\WINDOWS\system32>sqlplus /nolog
SQL> connect sys#'(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1522))
(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=myServiceName)))' as sysdba
Enter Password:
Connected.
SQL>
Optionally, under same folder, create structure - network\admin\tnsname.ora and create TNS name in there
