Relational Database Concepts

This foundational section covers what relational databases are, their components (tables, columns, rows), and key concepts like primary keys, foreign keys, and data integrity. Understanding these principles is critical before you even start writing SQL.

Retrieving Data using the SQL SELECT Statement

The SELECT statement is the cornerstone of SQL. This topic covers basic data retrieval, selecting specific columns, using aliases, and understanding how data is structured and presented.

Restricting and Sorting Data

Learn to filter rows using the WHERE clause with comparison operators, logical operators (AND, OR, NOT), and the IN, BETWEEN, LIKE, and IS NULL operators. Additionally, master the ORDER BY clause for sorting results in ascending or descending order, crucial for structured data presentation.

Using Single-Row Functions to Customize Output

Oracle SQL provides a rich set of single-row functions. This section involves understanding character functions (e.g., UPPER, LOWER, SUBSTR, LENGTH), number functions (e.g., ROUND, TRUNC, MOD), date functions (e.g., SYSDATE, MONTHS_BETWEEN, ADD_MONTHS), and general functions (e.g., NVL, COALESCE).

Using Conversion Functions and Conditional Expressions

Learn to explicitly and implicitly convert data types using functions like TO_CHAR, TO_NUMBER, and TO_DATE. Understand conditional expressions like CASE and DECODE, which allow for conditional logic within your queries, producing customized outputs based on specific criteria.

Reporting Aggregated Data Using Group Functions

This covers aggregate functions such as SUM, AVG, COUNT, MAX, and MIN, which operate on sets of rows to return a single result. Crucially, you'll learn to group rows using the GROUP BY clause and filter those groups using the HAVING clause, distinguishing it from the WHERE clause.

Displaying Data from Multiple Tables

A core skill in relational databases is joining tables. This section covers various join types: inner joins, outer joins (LEFT, RIGHT, FULL), and self-joins. Understanding join conditions and how to efficiently combine data from multiple sources is vital for `Oracle Database SQL exam objectives`.

Using Subqueries to Solve Queries

Subqueries (inner queries or nested queries) allow you to retrieve data that will be used in the main query. Learn about single-row subqueries, multiple-row subqueries (IN, ANY, ALL), and correlated subqueries. Subqueries are powerful tools for complex data retrieval.

Using SET Operators

SET operators like UNION, UNION ALL, INTERSECT, and MINUS combine the results of multiple SELECT statements. Understanding their distinct behaviors, such as handling duplicates and column compatibility, is key for advanced data manipulation.

Managing Tables using DML Statements

Data Manipulation Language (DML) statements are fundamental for interacting with data. This topic covers INSERT (adding new rows), UPDATE (modifying existing rows), and DELETE (removing rows) statements, as well as transaction control statements like COMMIT, ROLLBACK, and SAVEPOINT.

Managing Indexes, Synonyms, and Sequences

Indexes improve query performance, synonyms provide alternative names for database objects, and sequences generate unique numbers. This section covers how to create, alter, and drop these objects, which are important for database efficiency and usability.

Use DDL to Manage Tables and Their Relationships

Data Definition Language (DDL) is used to create and manage database objects. This includes creating, altering, and dropping tables, defining constraints (primary key, foreign key, unique, not null, check), and understanding the impact of these operations on data integrity.

Managing Views

Views are virtual tables based on the result-set of a SQL query. Learn how to create, alter, and drop views, and understand their benefits in simplifying complex queries, providing data security, and customizing data presentation. This is a common area of `1Z0-071 exam questions`.

Controlling User Access

Security is paramount in databases. This section covers granting and revoking system privileges and object privileges to control who can access and manipulate database objects. Understanding the principles of least privilege is important here.

Managing Objects with Data Dictionary Views

The Oracle Data Dictionary is a collection of read-only tables and views that provide information about the database itself. Learn to query these views (e.g., USER_TABLES, ALL_TABLES, DBA_TABLES) to obtain metadata about schemas, tables, columns, constraints, and more.

Managing Data in Different Time Zones

With global applications, handling time zones correctly is essential. This topic covers Oracle's support for time zone management, including data types like TIMESTAMP WITH TIME ZONE and TIMESTAMP WITH LOCAL TIME ZONE, and functions to convert between time zones.

Table Values Constructor in Oracle Database 23ai

The table values constructor allows us to define multiple rows using a single constructor for use in SQL statements.

◉ Setup

The following table is required to run the examples in this article.

drop table if exists t1;

create table t1 (

  id number,

  code varchar2(6),

  description varchar(25),

  constraint t1_pk primary key (id)

);

◉ INSERT

The table values constructor allows us to insert multiple rows into a table in a single step.

insert into t1

values (1, 'ONE', 'Description for ONE'),

       (2, 'TWO', 'Description for TWO'),

       (3, 'THREE', 'Description for THREE');

commit;

select * from t1;

        ID CODE   DESCRIPTION

---------- ------ -------------------------

         1   ONE      Description for ONE

         2   TWO     Description for TWO

         3   THREE  Description for THREE

SQL>

That's a single network round trip without having to combine all the insert statements into a PL/SQL block.

◉ SELECT

The same type of table values constructor can be used in the FROM clause of a SELECT statement. Notice we have to alias the column names so they are presented correctly.

select *

from   (values

          (4, 'FOUR', 'Description for FOUR'),

          (5, 'FIVE', 'Description for FIVE'),

          (6, 'SIX', 'Description for SIX')

       ) a (id, code, description);

        ID CODE DESCRIPTION

---------- ---- --------------------

         4   FOUR Description for FOUR

         5    FIVE  Description for FIVE

         6    SIX    Description for SIX

SQL>

◉ WITH Clause

The table values constructor can be used as part of a WITH clause.

with a (id, code, description) AS (

  values (7, 'SEVEN', 'Description for SEVEN'),

         (8, 'EIGHT', 'Description for EIGHT'),

         (9, 'NINE', 'Description for NINE')

)

select * from a;

        ID CODE  DESCRIPTION

---------- ----- ---------------------

         7   SEVEN Description for SEVEN

         8   EIGHT  Description for EIGHT

         9   NINE   Description for NINE

SQL>

◉ MERGE

The table values constructor can be used as the source data for a MERGE statement.

merge into t1 a

  using (values

          (4, 'FOUR', 'Description for FOUR'),

          (5, 'FIVE', 'Description for FIVE'),

          (6, 'SIX', 'Description for SIX')

        ) b (id, code, description)

  on (a.id = b.id)

  when matched then

    update set a.code        = b.code,

               a.description = b.description

  when not matched then

    insert (a.id, a.code, a.description)

    values (b.id, b.code, b.description);

3 rows merged.

SQL>

select * from t1;

        ID CODE   DESCRIPTION

---------- ------ -------------------------

         1   ONE      Description for ONE

         2   TWO     Description for TWO

         3   THREE  Description for THREE

         4   FOUR    Description for FOUR

         5   FIVE      Description for FIVE

         6   SIX        Description for SIX

6 rows selected.

Transport Layer Security (TLS) Connections without a Client Wallet in Oracle Database 23ai

In previous releases HTTPS callouts from the database required the use of a client wallet. From Oracle database 23ai onward we can use the operating system certificate store instead.

Operating systems usually have a certificate store containing the root certificates of popular certificate authorities. This allows the operating system to make trusted connections to sites using those root certificates. These certificate stores are kept up to date with operating patches. Oracle 23ai allows us to make use of the operating system certificate store, rather than having to use a wallet, which removes the burden of certificate management from us.

Test a URL From the Operating System

The simplest way to test a HTTPS URL is to use the curl command from the operating system command line. If a valid HTTPS connection is possible, we should get a "200 OK" response. We can see it works fine.

$ curl -is https://oracle-base.com/sitemap.xml | grep HTTP

HTTP/1.1 200 OK

$

This means the required root certificate is present in the operating system certificate store.

Create an ACL

In order to do a database callout we need an Access Control List (ACL) for the host. The following example creates an ACL for the host "oracle-base.com" on port 443. The principal is TESTUSER1, which is the user we will make the call from.

conn sys/SysPassword1@//localhost:1521/freepdb1 as sysdba

begin

  dbms_network_acl_admin.append_host_ace (

    host       => 'oracle-base.com', 

    lower_port => 443,

    upper_port => 443,

    ace        => xs$ace_type(privilege_list => xs$name_list('http'),

                              principal_name => 'testuser1',

                              principal_type => xs_acl.ptype_db)); 

end;

/

conn testuser1/testuser1@//localhost:1521/freepdb1

Test a Database Callout Without a Wallet

We create a procedure using the UTL_HTTP package to return the contents of a URL.

create or replace procedure show_html_from_url (

  p_url  in  varchar2

) as

  l_http_request   utl_http.req;

  l_http_response  utl_http.resp;

  l_text           varchar2(32767);

begin

  -- Make a http request and get the response.

  l_http_request  := utl_http.begin_request(p_url);

  l_http_response := utl_http.get_response(l_http_request);

  -- Loop through the response.

  begin

    loop

      utl_http.read_text(l_http_response, l_text, 32766);

      dbms_output.put_line (l_text);

    end loop;

  exception

    when utl_http.end_of_body then

      utl_http.end_response(l_http_response);

  end;

exception

  when others then

    utl_http.end_response(l_http_response);

    raise;

end show_html_from_url;

/

In previous releases attempting to use the procedure without opening a wallet would result in a certificate validation failure. That is not the case in Oracle 23ai, as we are using the operating system certificate store by default.

set serveroutput on long 1000000

exec show_html_from_url('https://oracle-base.com/sitemap.xml');

<?xml version="1.0" encoding="UTF-8"?>

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">

  <url>

... output removed ...

  <url>

</urlset>

PL/SQL procedure successfully completed.

SQL>

We could have achieved a similar result using HTTPURITYPE.

Test a Database Callout With a Wallet

We can still use a wallet containing the relevant root certificate, but once we reference the wallet it takes priority. If the wallet doesn't contain the correct root certificate, the call will fail. To demonstrate this we make a new wallet containing a self-signed certificate, rather than the root certificate of the URL we are calling.

mkdir -p /u01/wallet

orapki wallet create -wallet /u01/wallet -pwd WalletPasswd123 -auto_login

orapki wallet add -wallet /u01/wallet -pwd WalletPasswd123 \

  -dn "CN=`hostname`, OU=Example Department, O=Example Company, L=Birmingham, ST=West Midlands, C=GB" \

  -keysize 1024 -self_signed -validity 365

We connect to a new session, open the wallet, and attempt to run the procedure to make the callout. As expected, this results in a certificate validation failure.

conn testuser1/testuser1@//localhost:1521/freepdb1

set serveroutput on long 1000000

exec utl_http.set_wallet('file:/u01/wallet', null);

exec show_html_from_url('https://oracle-base.com/sitemap.xml');

We get the same error when we try to use HTTPURITYPE.

conn testuser1/testuser1@//localhost:1521/freepdb1

set serveroutput on

exec utl_http.set_wallet('file:/u01/wallet', null);

select HTTPURITYPE.createuri('https://oracle-base.com/sitemap.xml').getclob();

ERROR:

We add the correct certificate to the wallet.

orapki wallet add -wallet /u01/wallet -trusted_cert -cert "/tmp/ISRG Root X1.crt" -pwd WalletPasswd123

Now the previous tests work as expected.

conn testuser1/testuser1@//localhost:1521/freepdb1

set serveroutput on long 1000000

exec utl_http.set_wallet('file:/u01/wallet', null);

exec show_html_from_url('https://oracle-base.com/sitemap.xml');

Mark a Self-Signed Certificate as Trusted

We are not always working with certificates from a certificate authority. Sometimes we may need to make callouts to services using self-signed certificates. Fortunately we can mark self-signed certificates as trusted on the OS of the database server. The following actions were performed as the "root" user.

We create a self-signed certificate, as demonstrated.

mkdir -p ~/certs

openssl req \

  -newkey rsa:4096 -nodes -sha256 -keyout ~/certs/${HOSTNAME}.key \

  -x509 -days 3650 -out ~/certs/${HOSTNAME}.crt \

  -subj "/C=GB/ST=West Midlands/L=Birmingham/O=Example Company/OU=Devs/CN=Tim Hall/emailAddress=me@example.com"

We copy it to the "/etc/pki/ca-trust/source/anchors/" directory and run update-ca-trust to make the change take effect.

cp ~/certs/${HOSTNAME}.crt /etc/pki/ca-trust/source/anchors/

update-ca-trust

We use trust list to check the certificate is present.

# trust list --filter=ca-anchors | grep -B 4 -A 2 "Tim Hall"

pkcs11:id=%EE%3A%98%8F%93%C2%64%23%E0%42%7F%52%97%54%6D%87%7F%C0%2F%05;type=cert

    type: certificate

    label: Tim Hall

    trust: anchor

    category: authority
