Introduction

Home - Tab
• The Home tab is the starting point for your Oracle
Live SQL session after you login.

SQL Worksheet - Tab
Provides you the ability to write SQL statements and
execute them against the Oracle Live SQL schema.
As an example you can see the execution of the
select sysdate from dual statement in the
example on the right.

SQL Session- Tab
Provides access to information of your current
session and previous sessions. On the main tab you
can see information of the most recent statements
executed against your schema. Your Live SQL
session provides temporary access to an Oracle
Database schema. Your session also persists a
record of each SQL statement run. To preserve your
work save your session as a SQL script. You can
also reset your session to return to fresh empty
schema.
A number of sub-tabs are provided:
•Previous sessions
•Utilization
•NLS
•Preferences

SQL Session- Tab
Previous Sessions:
Previous Sessions are a logged collection of SQL
statements that you have entered using this system
in the past. Your lease on a database schema may
have expired, however you can view these SQL
statements, replay the SQL statements in your
current session, or save an old session as a named
SQL script.

SQL Session- Tab
Utilization:
Your Live SQL usage is controlled by various limits.
You can see your consumption of these limits using
this page.

SQL Session- Tab
NLS:
Each Live SQL page request is a new database
session. To preserve NLS state between SQL
statement execution over multiple page posts this
application remembers your NLS settings and
applies them to ensure each session has proper
NLS.

SQL Session- Tab
Preferences:
In essence the only preference you can currently set
is the “maximum rows to query”

Schema Tab
Schema:
A database schema is a logical container for data
structures, called schema objects. Examples of
schema objects are tables, stored procedures and
indexes. This Live SQL application automatically
creates a schema for your use. Your schema will be
allocated to you for the duration of your Live SQL
session.

Schema Tab
Default Schema:
By default you will have your own schema and a
number of pre-populated schema’s which you can
use as an example to run some code against. For
example, the Human Resources (HR), Sales History
(SH) and World Data (WORLD) schema are
available from the right hand side menu.

Schema Tab
Example Schema:
In the example on the right you can see the content
of the sales history (SH) schema which is filled with
a number of objects.

Schema Tab
Example Schema:
When clicking on one of the tables (in this case the
costs table) you will be able to see the definition of
the table. Interesting to see is that also a number of
syntax examples is given.
SQL
Provides a number of SQL operations example
JAVA
Provides an example of a select and a insert
statement
PL/SQL
Provides an example of a Package to perform basic
Table Operations.
Perl
Provides an example of perl code

select PROD_ID,TIME_ID,PROMO_ID,CHANNEL_ID,UNIT_COST,UNIT_PRICE from COSTS
select PROD_ID,TIME_ID,PROMO_ID,CHANNEL_ID,UNIT_COST,UNIT_PRICE from COSTS where
insert into COSTS ( PROD_ID,TIME_ID,PROMO_ID,CHANNEL_ID,UNIT_COST,UNIT_PRICE ) values (
:PROD_ID,:TIME_ID,:PROMO_ID,:CHANNEL_ID,:UNIT_COST,:UNIT_PRICE );
update COSTS set PROD_ID= :PROD_ID,TIME_ID= :TIME_ID,PROMO_ID= :PROMO_ID,CHANNEL_ID= :CHANNEL_ID,UNIT_COST=
:UNIT_COST,UNIT_PRICE= :UNIT_PRICE where
delete from COSTS where
SQL Example(s)

Java select example
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
public class TestSQL {
public void getEmps() throws SQLException{
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
Connection conn = DriverManager.getConnection("", "myusername", "my password");
PreparedStatement statement = conn.prepareStatement("select PROD_ID,TIME_ID,PROMO_ID,CHANNEL_ID,UNIT_COST,UNIT_PRICE from
COSTS where ");
ResultSet resultSet = statement.executeQuery();
while(resultSet.next()){
System.out.println(resultSet.getObject(PROD_ID));
System.out.println(resultSet.getObject(TIME_ID));
System.out.println(resultSet.getObject(PROMO_ID));
System.out.println(resultSet.getObject(CHANNEL_ID));
System.out.println(resultSet.getObject(UNIT_COST));
System.out.println(resultSet.getObject(UNIT_PRICE));
}
}
}

Java Insert example
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
public class TestSQL {
public void getEmps() throws SQLException{
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
Connection conn = DriverManager.getConnection("", "myusername", "my password");
PreparedStatement statement = conn.prepareStatement("insert into COSTS " +
" (PROD_ID,TIME_ID,PROMO_ID,CHANNEL_ID,UNIT_COST,UNIT_PRICE)" +
" values " +
" (:PROD_ID,:TIME_ID,:PROMO_ID,:CHANNEL_ID,:UNIT_COST,:UNIT_PRICE) ");
statement.setObject(?, "VALUE FOR PROD_ID");
statement.setObject(?, "VALUE FOR TIME_ID");
statement.setObject(?, "VALUE FOR PROMO_ID");
statement.setObject(?, "VALUE FOR CHANNEL_ID");
statement.setObject(?, "VALUE FOR UNIT_COST");
statement.setObject(?, "VALUE FOR UNIT_PRICE");
statement.execute();
}
}

PL/SQL example
create or replace package COSTS_METHODS
as
procedure add_row (
p_PROD_ID in NUMBER default null
,p_TIME_ID in DATE default null
,p_PROMO_ID in NUMBER default null
,p_CHANNEL_ID in NUMBER default null
,p_UNIT_COST in NUMBER default null
,p_UNIT_PRICE in NUMBER default null
);
procedure update_row (
);
procedure delete_row (
);
end COSTS_METHODS;
/
create or replace package body COSTS_METHODS
as
procedure add_row (
)
is
begin
insert into COSTS
( PROD_ID, TIME_ID, PROMO_ID, CHANNEL_ID, UNIT_COST, UNIT_PRICE)
values
( p_PROD_ID, p_TIME_ID, p_PROMO_ID, p_CHANNEL_ID, p_UNIT_COST, p_UNIT_PRICE);
end add_row;
procedure update_row (
)
is
begin
update COSTS
set PROD_ID=p_PROD_ID, TIME_ID=p_TIME_ID, PROMO_ID=p_PROMO_ID, CHANNEL_ID=p_CHANNEL_ID, UNIT_COST=p_UNIT_COST, UNIT_PRICE=p_UNIT_PRICE
where
();
end update_row;
procedure delete_row (
)
is
begin
delete COSTS
where
;
end delete_row;
end COSTS_METHODS;

show errors

Perl example
use DBI;
if (!($dbh = DBI->connect
("DBI:Oracle:XE","scott","tiger")))
{
die ("Failed to connect to database: " . DBI-
>errstr);
};
$sql =qq(
"SELECT ".
"FROM COSTS ".
"WHERE ");
if (!($sth = $dbh->prepare ($sql)))
{
die ("Failed to prepare statement: " . DBI-
>errstr);
};
$sth->execute;
my @row;
while (@row = $sth->fetchrow_array) { # retrieve one
row
print join(", ", @row), "n";
}
$sth->finish;
$dbh->disconnect;
use DBI;
if (!($dbh = DBI->connect
("DBI:Oracle:XE","scott","tiger")))
{
die ("Failed to connect to database: " . DBI->errstr);
};
$sql =qq(
"SELECT ".
"FROM COSTS ".
"WHERE ");
if (!($sth = $dbh->prepare ($sql)))
{
die ("Failed to prepare statement: " . DBI->errstr);
};
$sth->execute;
my @row;
while (@row = $sth->fetchrow_array) { # retrieve one row
print join(", ", @row), "n";
}
$sth->finish;
$dbh->disconnect;

Schema Tab
Creating a object:
When under your own schema you have the option
to create objects within your own schema. As can be
seen in the example on the right you have the four
options:
•Create object
•Create typical database objects using graphic
user interface.
•SQL Worksheet
•Manually enter SQL CREATE command
using the SQL worksheet.
•Upload Script
•Upload a SQL script from your client
computer.
•Using Community Code
•Create database objects using code
developed by others.

Schema Tab
Creating a object:
When using the create object you will have a guided
GUI way of creating the following objects:
• Table
• View
• PL/SQL Procedure
• PL/SQL Function
• PL/SQL Package
• Sequence
• Type
• Trigger
• Index
• Synonym

Design Tab
Use this page to rapidly design a schema. Click the
Add Table(s) button to add one or more tables. This
design tool uses a SQL shorthand syntax to speed
data model design. Once designed, you create a
SQL Script which will be available under My Scripts
that can be run to create the objects in your current
schema or run within another database.

My Scripts Tab
Use this page to quickly get access to the scripts
you have created. To save your "code" enter
commands in the SQL Worksheet. Once you have a
collection of work you wish to save click the Save
Session button to save your SQL session history as
a SQL Script. Once you save your work as a named
SQL script you can annotate, share, edit and replay
the scripts

Community Code Tab
Use this page to search for code that is created by
and shared with the community. Examples can be
found in this location.
