\nWant to test some DDL, a query, check an execution plan? You need only a browser. And you can copy-paste, or simply link, your test-case in a forum, a tweet, an e-mail, a tweet. Here is a small list (expecting to grow from your comments) of free online services which can run with an Oracle Database: SQL Fiddle, Rextester, db<>fiddle and Oracle Live SQL
\n

\n

SQL Fiddle

\n

SQL Fiddle let you build a schema and run DDL on the following databases:

\n\n

As an Oracle user, the Oracle 11gR2 is not very useful as it is a version from 2010. But there’s a simple reason for that: that’s the latest free version – the Oracle XE Edition. And a free online service can run only free software. Now that Oracle plans to release an XE version every year, this should be better soon.

Rextester

\n

Rextester is a service to compile code online, in a lot of languages and also the following databases:

\n\n

Example: http://rextester.com/QCYJF41984

\n

Rextester has also an API where you can run a query and get a JSON answer:

\n
\n$ curl -s  --request POST --data 'LanguageChoice=35 Program=select * from dual' http://rextester.com/rundotnet/api\n{\"Warnings\":null,\"Errors\":null,\"Result\":\"\\u003ctable class=\\\"sqloutput\\\"\\u003e\\u003ctbody\\u003e\\u003ctr\\u003e\\u003cth\\u003e\\u0026nbsp;\\u0026nbsp;\\u003c/th\\u003e\\r\\n\\u003cth\\u003eDUMMY\\u003c/th\\u003e\\r\\n\\u003c/tr\\u003e\\r\\n\\u003ctr\\u003e\\u003ctd\\u003e1\\u003c/td\\u003e\\r\\n\\u003ctd\\u003eX\\u003c/td\\u003e\\r\\n\\u003c/tr\\u003e\\r\\n\\u003c/tbody\\u003e\\u003c/table\\u003e\\r\\n\",\"Stats\":\"absolute service time: 1,37 sec\",\"Files\":null}\n
\n

The answer has the result as an HTML table:

\n
\n$ curl -s  --request POST --data 'LanguageChoice=35 Program=select * from dual' http://rextester.com/rundotnet/api | jq -r .Result\n<table class=\"sqloutput\"><tbody><tr><th> nbsp; nbsp;</th>\n<th>DUMMY</th>\n</tr>\n<tr><td>1</td>\n<td>X</td>\n</tr>\n</tbody></table>\n
\n

Here is my SELECT * FROM DUAL:

\n
\n$ curl -s  --request POST --data 'LanguageChoice=35 Program=select * from dual' http://rextester.com/rundotnet/api | jq -r .Result | lynx -dump -stdin\n       DUMMY\n    1  X\n
\n

db<>fiddle

\n

db<>fiddle has a very nice interface, easy to link and easy to paste to StackOverflow (click on ‘markdown’)

\n\n

Example: http://dbfiddle.uk/?rdbms=oracle_11.2&fiddle=948a067dd17780ca65b01243751c2cb0

Oracle Live SQL

\n

Finally, you can also run on the latest release of Oracle, with a service provided by Oracle itself: Live SQL.

\n\n
