PL/SQL Developer

What is PL/SQL Developer?

• PL/SQL Developer is an Integrated Development Environment that is specifically targeted at the development.

• PL/SQL Developer has its focus on PL/SQL development. But don’t underestimate the possibilities of the SQL Command Window.


PL/SQL Developer - installation


System requirements• PL/SQL Developer will run on:

– Windows all release so far,– Mac OS – is not supported - but you can run on Virtual Machine like

CrossOver more installation info: http://dgielis.blogspot.fr/2010/09/plsql-developer-on-osx.html

– Linux – not support as well - but on a Linux box you can use Wine – more info: http://johanlouwers.blogspot.fr/2008/09/plsql-developer-on-linux.html

• The supported Oracle Server versions are 7.x, 8.x, 8i, 9i, 10g and 11g on any platform.

• To connect to an Oracle database, PL/SQL Developer requires a 32-bit SQL*Net, Net 8, Net 9, Net 10

or Net 11 version, in other hand it

require Oracle Instant Client (32-bit)

PL/SQL Developer - installation

Easy installation? – steps (for Windows)1) Download PL/SQL Developer (9.0.6) from DFS: G:\Applications\AllroundAutomations

2) Run the setup,

3) Download Oracle Instant Client 32-bit version from Oracle site,http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html

4) Unpack it under C:\ProgramFiles\InstantClient,

5) Create directories C:\ProgramFiles\InstantClient\network\admin,

6) Create or past inside above directory tnsnames.ora file,

7) Launch PL/SQL Developer,


PL/SQL Developer – first start up

If you started PL/SQL Developer without connecting to DFS, go to:

Tools > Preferences >

Oracle / Connection

you can select the Oracle Home with the correct TNSNAMES.ORA file.


tnsnames.ora file directory

OCI.dll librarylocation


PL/SQL Developer - setup at CERNWe don’t need to create additional network/admin directories inside InstantClient directory. Instead of that we can specify location of tnsnames.ora file on DFS: G:\Applications\Oracle\ADMIN\tnsnames.ora

tnsnames.ora file will be always up to date

SQL Developer


What is Oracle SQL Developer?

- Oracle SQL Developer is a free graphical tool for database development. Using SQL Developer, you can browse database objects, run SQL statements and SQL scripts, and edit and debug PL/SQL statements.

- Free download from Oracle website:

http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html

System requirements- SQL Developer can connect to any Oracle Database version 9.2.0.1

and

later and runs on Windows, Linux, and Mac OSX.

SQL Developer

Advantages

• No need to install anything, simple unzip downloaded

package and software is ready to use,

• Portable – copy unzipped files on flash drive and you can

use it on any PC,

• You can connect in parallel to several different databases,

Benthic - Golden 6.x

• Golden 6.x- Is much more simpler tools that two previous one but still quite handy for SQL statements.

• System requirements- Golden is available only for Windows, however the same like for PL/SQL Developer we can use workaround to install it on MacOS and Linux,

- Oracle Instant Client 32-bit is necessary.



• Installation steps- Copy the Instant Client dll's to C:\Oracle

- Put C:\Oracle at the beginning of PATH system variable,

- Copy tnsnames.ora to C:\Oracle

- Add the system variable TNS_ADMIN with a value of C:\Oracle

- Set the OCI DLL field of Golden's Login Options window to "C:\Oracle\oci.dll" (you will have to restart Golden after setting this value).


• Login



• Main window – simple view but sometimes is exactly what we need



• Simple query building



• DBMS Output window (F10) - for PL/SQL scripts

Cherry on the cake


• rlwrap - is a 'readline wrapper', a small utility that uses the GNU readline library to allow the editing of keyboard input for any command.

rlwrap

• Finally something only on Linux - rlwrap compiles and runs on most Unix(-like) systems, including cygwin

• Installationgunzip rlwrap*.gz

tar -xvf rlwrap*.tar

cd rlwrap*

./configure

make

make check

make install


rlwrap

• Usage – together with SQL*Plus or RMAN
