Introduction





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



SQL Worksheet - TabProvides 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- TabProvides 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- TabPrevious 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- TabUtilization:Your Live SQL usage is controlled by various limits. You can see your consumption of these limits using this page.



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



Schema TabSchema: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 TabDefault 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 TabExample 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 TabExample 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.

SQLProvides a number of SQL operations example

JAVAProvides an example of a select and a insert statement

PL/SQLProvides an example of a Package to perform basic Table Operations.

PerlProvides 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 exampleimport 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 exampleimport 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(); } }

Schema TabCreating 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 TabCreating 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 TabUse 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 TabUse 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 TabUse this page to search for code that is created by and shared with the community. Examples can be found in this location.
