Session from ILOUG I presented in May, 2016
Introducing the new tool from the developers of SQL Developer: SQLcl – a new command line tool from the SQL Developer team that might replace SQL*Plus and all of its functions which has been around for over 30 years!
In this session, we will explore the new functionality of the SQLcl, and use a live demonstration to show what SQLcl has to offer over the old SQL*Plus. We will use real life example to see what makes this tool such a time saver in day-to-day tasks for DBAs and developers who prefer using the command line interface.

• SQL*Plus forces us to use GUI tools to complete some basic tasks
• Easy to understand, a bit hard to use
• Not easy for new users or developers
http://brillix.co.il6
7. Introducing: SQLcl
• SQLcl is a new command line interface (CLI) for SQL developers,
report users, and DBAs
• It is part of the SQL Developer suite – developed by the same
team: Oracle Database Development Tools Team
• Does (or will do) most of what SQL*Plus can do, and much more
• Main focus: making life easier for CLI users
• Minimal installation, minimal requirements
http://brillix.co.il7
8. Current Status (May 2016)
• Still in Early Adopter version
• current version: 4.2.0.16.131.1023 RC, May 13, 2016
• QA is still logging bugs from SQL*Plus regression tests
• Version comes out every couple of months
• Adding support for existing SQL*Plus commands/syntax
• Adding new commands and functionality
• The team is accepting bug reports and enhancement requests
from the public
http://brillix.co.il8
9. Prerequisites
• Very small footprint: 12MB
• Tool is Java based so it can run on Windows, Linux, and OS/X
• Java 7/8 JRE (runtime environment - no need for JDK)
• No need for installer or setup
• No need for any other additional software or special license
• No need for Oracle Client
http://brillix.co.il9
10. Installing
• Download from: SQLcl Developer tool OTN Page
• Unzip the file
• Verify has +x if in Linux/OSX
• Run it
http://brillix.co.il10
12. Connecting to the Database
• When no Oracle Client: Using thin connection:
EZConnect connect style out of the box
connect host:port/service
• Support TNS, Thick and LDAP connection when Oracle home
detected
• Auto-complete connection strings from last connections AND
tnsnames.ora
http://brillix.co.il12
13. Object Completion and Easy Edit
• Use the tab key to complete commands
• Can be used to list tables, views or other queriable objects
• Can be used to replace the * with actual column names
• Use the arrow keys to move around the command
• Use CTRL+W and CTRL+S to jump to the beginning/end of
commands
http://brillix.co.il13
14. Command History
• 100 command history buffer
• Commands are persistent between sessions (watch out for security!)
• User SET NOHISTORY to blacklist commands to not go into history
• Use UP and DOWN arrow keys to access the old commands
• Usage:
history
history usage
history time
history script
history full
history clear [session?]
• Load from history into command buffer:
history <number>
http://brillix.co.il14
15. Describe, Information and Info+
• Describe lists the column of the tables just like SQL*Plus
• Information shows column names, default values, indexes and
constraints.
• In 12c database information shows table statistics and In
memory status
• Works for table, views, sequences, and code objects
• Info+ shows additional information regarding column statistics
and column histograms
http://brillix.co.il15
16. SHOW ALL and SHOW ALL+
• The show all command is familiar from SQL*Plus – it will show
all the parameters for the SQL*Plus settings
• The show all+ command will show the show all command and
some perks: available tns entries, list of pdbs, connection
settings, instance settings, nls settings, and more!
http://brillix.co.il16
17. Repeat
• Repeats the current SQL or PL/SQL in the buffer the specified
number of times with specified sleep intervals
• Looks like the “watch” command in Linux
• Usage:
repeat <iterations> <sleep>
http://brillix.co.il17
18. Repeat as “tail -f alert.log”
• Jeff Smith (@thatjeffsmith) had a cool implementation for the
repeat command on Oracle 12c:
• tail –f on the alert log
http://brillix.co.il18
SELECT
To_Char(Originating_Timestamp, 'DD-MON-YYYY HH24:MI:SSxFF') Time_Entry,
substr(trim(message_text), 0, 75) || '...' ABBR_MESSAGE_TEXT
FROM X$dbgalertext
ORDER BY Originating_Timestamp DESC, indx desc
fetch FIRST 15 ROWS ONLY;
19. DDL and DBMS_METADATA
• Extract DDL of objects using a single command
DDL <object name>
• Uses DBMS_METADATA.GET_DDL to extract the object
• We can modify the output using SET DDL:
http://brillix.co.il19
SET DDL
SET DDL [[ PRETTY | SQLTERMINATOR | CONSTRAINTS | REF_CONSTRAINTS |
CONSTRAINTS_AS_ALTER|OID | SIZE_BYTE_KEYWORD | PARTITIONING |
SEGMENT_ATTRIBUTES | STORAGE | TABLESPACE | SPECIFICATION |
BODY | FORCE | INSERT | |INHERIT | RESET] {on|off}
]| OFF ]
20. OERR
• OERR shows an error message just like the oerr in the
command line (in *nix systems)
http://brillix.co.il20
SQL> oerr ora-0
00000. 00000 - "normal, successful completion"
*Cause: Normal exit.
*Action: None.
SQL> oerr ora-1
00001. 00000 - "unique constraint (%s.%s) violated"
*Cause: An UPDATE or INSERT statement attempted to insert a duplicate
key.
For Trusted Oracle configured in DBMS MAC mode, you may see
this message if a duplicate entry exists at a different level.
*Action: Either remove the unique restriction or do not insert the key.
21. Alias
• Alias is a command which allows us to save a SQL, PL/SQL or
SQL*Plus scripts, and assign it a shortcut command.
• Command can receive parameters using bind variables
• Aliases are session persistent and being saved
• Usage:
• alias - for list of aliases
• alias list <aliasName> - for definition
• Setting an alias:
• alias my_command=sql; (terminate with ;)
• alias my_code=begin command; end; (terminate with /)
http://brillix.co.il21
22. Alias Example
• We’re tired of running the dbms_xplan after we explain a query
• So we set this alias:
http://brillix.co.il22
alias plan=select * from table(dbms_xplan.display);
SQL> explain plan for select * From dual;
Explained.
SQL> plan
PLAN_TABLE_OUTPUT
---------------------------------------------------------------
Plan hash value: 272002086
23. CTAS
• Extract DDL for a table and use it to recreate another table
using select * from
• Useful when we want to copy a table with partitions or a primary
key
• Might not stay in the final version – have a lot of small and
annoying issues
• Usage:
ctas table new_table
http://brillix.co.il23
24. SQLPATH
• SQLPATH is the order in which the CLI is looking for sql scripts
(both in SQL*Plus and SQLcl)
• Running a script not from the path requires full path location
• Default search order is:
1. Current cd directory
2. Current running directory
3. The rest of the sqlpath
• Show SQLPATH will show that current search path
http://brillix.co.il24
25. CD command
• When we want to change the path in SQL*Plus, we usually can’t.
• SQLcl comes with CD command to change that path and make it
easier to run scripts:
• Usage:
cd /u01/app/oracle/scripts
Show SQLPATH
http://brillix.co.il25
26. Bridge
• Used mainly to script data move between two connections from
the client (no server direct server connections)
• The following functionality is available:
1. Query tables in other connections
2. Query tables in multiple connections in the same statement
3. Insert data from one connection into another
4. Create a table and insert data into it from another connection
http://brillix.co.il26
27. Bridge (cont.)
• Uses JDBC connection string to connect our client to the remote
connection.
• Creates a table with the results in the database
• Usage:
BRIDGE <targetTableName> as "<jdbcURL>"(<sqlQuery>);
• Example:
http://brillix.co.il27
BRIDGE dept_remote as
“jdbc:oracle:thin:scott/tiger@localhost:1521/orcl"(select * from dept);
28. Pretty Input
• Using the SQL Developer formatting rules, it will change our input into
well formatted commands.
• Use the SQLFORMATPATH to point to the SQL Developer rule file (XML)
http://brillix.co.il28
SQL> select * from dual;
D
-
X
SQL> format buffer;
1 SELECT
2 *
3 FROM
4* dual
29. SQL*Plus Output
• SQL*Plus output is generated as text tables
• We can output the data as HTML but the will take over
everything we do in SQL*Plus (i.e. describe command)
• We can’t use colors in our output
• We can’t generate other types of useful outputs (CSV is really
hard for example)
http://brillix.co.il29
30. Generating Pretty Output
• Outputting query results becomes easier with the “set sqlformat”
command (also available in SQL Developer)
• We can create a query in the “regular” way and then switch
between the different output styles:
• ANSIConsole
• Fixed column size output
• XML or JSON output
• HTML output generates a built in search field and a responsive
html output for the result only
http://brillix.co.il30
31. Generating Other Useful Outputs
• We can generate loader ready output (with “|” as a delimiter)
• We can generate insert commands
• We can easily generate CSV output
• Usage:
set sqlformat { csv,html,xml,json,ansiconsole,insert,
loader,fixed,default}
http://brillix.co.il31
32. Load Data From CSV File
• Loads a comma separated value (csv) file into a table
• The first row of the file must be a header row and the file must
be encoded UTF8
• The load is processed with 50 rows per batch
• Usage:
LOAD [schema.]table_name[@db_link] file_name
http://brillix.co.il32
33. SCRIPT
• SQLcl exposes javascript scripting with nashorn to make things
very scriptable
• This means we can create our own commands inside SQLcl
using JavaScript
• For more information (and DEMO), check out Kris Rice’s blog
(product manger for SQLcl): http://krisrice.blogspot.com/
http://brillix.co.il33
35. Conclusion

In this session, we will talk about SQLcl, which is a new command line tool developed by the SQL Developer team at Oracle Database Development Tools Team. The purpose of this session is to introduce this great tool to you. Even though it is still in its early adopter version, it has some great new features that I thought developers and DBAs ought to know about.
We will talk about the old SQLPlus and what made it so great.
I will show you how to install SQLcl and some basic functionality.
We will talk about some of the new features – there are a lot of them, so I picked only the ones I thought will be really-really cool and we’ll have a live demos for most of them
Feel free to raise your hand with questions during the session but I promise we WILL also have time for Q&A in the end of the session.
[Audience interaction] Let me start with a question: please raise your hand if you never used SQLPlus. Is there anyone here who does not use it? I didn’t think so – and I don’t think anybody here will find it as a big surprise. SQLPlus is one of Oracle’s oldest tools. It has been around for at least 30 years – it came out in Oracle database version 5, which came out in 1985. Before that, Oracle command line tool was called UFI ("User Friendly Interface") which was anything but user friendly. That tool was in use in Oracle database version 2 through 4 (1979 to 1985).
The SQLPlus might sound like a simple tool but it is actually not. SQLPlus is one of the more complicated tools Oracle puts in their client package. It is the first tool to be updated when syntax changes, it interacts with the grid infrastructure tools seamlessly (for example – if you shut down a RAC instance using SQLPlus, the grid infrastructure will be aware this was intentional and will not try to restart the instance) .
Over the years, this tool was updated a lot but we still used an old tool with not a lot of new features. The tool did get some bugs fixed and some new syntax updates but that was about it – there was little to no new functionality introduced to could make life easier on the end users.
The guys in Oracle tried to add some new features to the SQLPlus. They added support for markup language so we could output our queries as html reports – some of the internal tools such as AWR and ASH are using it. They tried to introduce Windows based SQLPlus called SQLPlusw and even had a web based version called iSQLPlus.
Oracle also recognized that SQLPlus is been used a lot of scripting and maintenance (they are using it too, themselves) so they also provided a lot of support of such things. For example the use of variables, prompt command, and user challenge like accept and so on. As of Oracle 12cR1, SQLPlus is the only command line tool Oracle provides for SQL queries and database maintenance.
As you are about to see soon, this tool looks very similar to the old SQLPlus, but has a lot of new functionality. Most of the old features we duplicated but let me put it up front: there is no guarantee (as of now) that it will ever replace the SQLPlus completely it in the future but I’m sure you might want to consider it after you see what it can do.
About a year ago, the development team for SQL Developer, which is the not-so-new GUI interface that oracle provide free-of-charge to its customers, decided that they want to cover one of the areas that the GUI tool did not cover at all. That area was the command line interface area and automatic scripting. They started rewriting the functionality provided by SQLPlus into Java code and added some cool new features. Their goal was to make the new tool as similar to the SQLPlus as possible but still introduce some things that users had been complaining about for the last 30 years. The really exciting thing here is the team members are really open for suggestions. I know of at least couple of features that development team added to SQLcl just because someone twitted it to them, it sounded cool and not hard to implement…
The actual footprint on the SQLcl tool is really small – it's only 11 or 12 Megabytes in size.
Like the SQL Developer, this is a Java based tool and it requires Java 1.7 or 1.8 to run. Unlike SQL Developer, it requires only the Java runtime environment (JRE) and not the Java development kit (JDK). SQLcl does not require anything else – for example, it does not require an Oracle Client at all but it does recognize it if you have one, and give you some extra features like thick client support. Since it Java based, it is not platform specific and can run on Windows, Linux or OS X but I didn’t try it on anything else.
The first thing you will need to do in order to use SQLcl is download it from the SQL Developer site. You can find it under the SQL Developer 4.1 download page, at the bottom. It will be under SQLcl Early Adopter download link. While preparing for this session and building my presentation, there were at least three or four new versions that came out, so keep your eyes open for new releases – at least until they release a stable production version.
The installation process is very short and simple: download, unzip, and run. If you're using Linux you might need to change the sql file with the +x (execute flag) for making it an executable but that is about it. We are ready to run the SQLcl and use it.
Let's see how it looks when we're connecting for the first time. we said we don't need an Oracle Client so we will be using the EZConnect JDBC style connection string. I am using my local database for this presentation so we'll use the local IP address 192.168.56.101, my listener's port of 1521 and the database name for the connection.
The first new and cool feature I'd like to show you now is that I don't have to know where I want to connect. Let's say I want to connect to a database but I am unsure of its TNS connection name. I write connect zohar@ and then the TAB key and I get a list of all available connection. The list is derived from my tnsnames.ora file and recent connections. If you remember a partial name of the tnsnames it will autocomplete it.
Once we're connected we can see the jdbc connection information by using the "show jdbc" command.
Watch out for the bug in edit command
Watch out for the bug in host command
Now we know which table we want to query, but we're not really sure what is the table structure. We can use the good old describe command for that, but sometimes it is just not enough. When using the describe command, we can't tell if there are indexes on the table, what constraint the table follows - primary or foreign constraints, or what are the columns' default values. When using SQLPlus, this would be the time to start querying around the data dictionary to find all the relevant information. When using SQLcl all we need to do is run the information command (info for short) and we get a detailed screen with all relevant information. Here we can see the table columns, indexes, primary key, foreign key constraint, and default values. Pretty cool, right?
Even then, that is sometimes not enough. What if we want to know more details about the table statistics? And what about the column statistics and histograms? we can use the info+ command where we can see all that information.
Let's continue to the next small and cool feature. Let's say you need to query a table over and over so see when it changes. For example, checking the status of the data guard of if you want to see if there are new user blocking locks and so on. Until now, we had to run it manually every few seconds. In other cases, we built scripts that will loop the query but we didn't have any good way to do it easily. Now we do. Once the query is in the buffer, we can use the repeat command to run it again and again. The repeat command runs the query from the buffer and accepts two parameters: The number of times we want to run the query and the interval in which we will ran it at. For example, if we want to run a query 5 times with 3 seconds interval we will use the "repeat 5 3". As I said, this is really useful if you're impatient as I am…
Jeff Smith from the development team had a great example for implementing this feature. He used it on Oracle 12c to run a live tail command on his alert log using a query. It looked something like this:
http://www.thatjeffsmith.com/archive/2015/04/tailing-the-alert-log-with-sqlcl/
One of the disadvantages of being a consultant is that sometimes you get to a customer who doesn't use any graphical tools and we have to get by with what we have. This is why low footprint tools are so important to us. When working with these customers, we sometimes need to extract a structure of an object – and that is a really hard work. Most of the DBAs I know use GUI tools to do it, but as a consultant, we don't always have this luxury.
SQLcl solves this problem by introducing a new short code command – the "ddl" command. This will extract the structure of an object in a single, simple command: ddl myobject to get a valid and formatted ddl command. This will work with most objects: table, view, synonym, sequence and even an index.
This feature uses the dbms_metadata package so we can be sure the command is valid but it also reformats it so we can be sure the command is readable.
Ah ha! SQLcl comes with an alias feature. The alias feature allows us, just like in unix or linux operating system, to name a command with an alias and use that when we want to run it. For example – if we create a new alias ddl_no_seg
Let's say we want to create a table as select but want to keep the original structure of the table we select. For example, if we want it to have the same partition structure or prmary key. In that case, we will need to extract a ddl, fix whatever need fixing and then run the command. SQLcl helps us with the ctas command: ctas old_table new_table will generate a command that builds the table with the same structure of the queried table and the select star from that table.
Bug: when using 'SEGMENT_ATTRIBUTES' false command generated is invalid.
Bug: when using ctas, the primary key name is not modified so it might fail when running the generated script.
Even the HTML output is different: the output is responsive, has smartphone and ipad support (small screens and landscape view) and so on. Just note that the old markup doesn't work yet.
When we said we can output the data as csv, but what if we want to load data into our tablespace from CSV (excel files for example)?
We can do that as well: use the LOAD command with the table name and csv file it there you have it. In order for this to work, we need to make sure the file format is exactly as the format the sqlformat csv output it: the first line should be the list of columns and the data should be comma-delimited. It is autocommited every 50 records but this is something we can change if we need to.
