Included with SQL Developer, also available as a separate download/program
 Java 8 JRE or higher
 Small download
 Unzip & Go

What’s New?

Customize/Pimp Your Ride

Fun
set sqlprompt "@|blue _USER|@@@|green_CONNECT_IDENTIFIER|@@|blue >|@"

SYS@orcl >alias plan =
SELECT * FROM
TABLE(DBMS_XPLAN.DISPLAY_CURSOR)
SYS@orcl >alias plan2 =
SELECT * FROM TABLE
(DBMS_XPLAN.DISPLAY_CURSOR(
:ID, :CHILD))
Practical: Re-use Your
Commands & Scripts
With ALIAS

Commands: Alias
Make your own
‘commands’ – map
SQL w/binds to an
alias
Example:
 Show me all
tables who have
columns using
:DATA_TYPE

Commands: CTAS
DDL sent to BUFFER – edit or execute

Commands: DDL
 generate object DDL
 create scripts using DDL
& SPOOL commands

 Automatically format query results
 SET SQLFORMAT csv
 html
 xml
 json
 csv
 insert
 loader
 ansiconsole
DEMO – Output Formatting

ANSICONSOLE??? Escape Sequences to Effect Console Output
Fancy Output, LOOP(
 get a PAGE…
 ‘smart’ size Columns…
 PAGE++
 )

ANSICONSOLE Formatting
Fetch page, format column sizes, print, continue…
SET sqlformat ansiconsole

Demo, ANSI Console Coloring

DEMO – SQL History
Statement Execution History
 Last 100 statements
 Persist between sessions
 Cycle through using UP/DN
 Full List
 Also Tracks Total Execution
Time & # of Executions
 Filter Types of Commands
saved in History

INFOrmation– a better DESCribe
Object Metadata
Example: Tables
 Keys
 Comments
 INMEMORY status
 Stats
 Indexes

Demo, Object Completion
Think ‘the Ctrl+Spacebar stuff’
in SQL Developer
 activated with a <TAB>
 object, column names, and
keywords

Demo, Command Completion
ALTER SESSION {ENABLE | DISABLE | FORCE} PARALLEL
{DML|DDL|QUERY} [PARALLEL int]

Client Side Scripting? (JavaScript)
