Recruit Oracle PL/SQL Programmers
Oracle Corporation designed Procedural Language for SQL (PL/SQL) as an extension to Structured Query Language (SQL) for use with Oracle database. PL/SQL is a powerful and easy-to-learn programming language that shares similar syntax with SQL. This language is compiled and stored in the database, leading to maximum efficiency as the same server process executes both SQL and PL/SQL. In addition, PL/SQL ensures logical processing of SQL queries, thereby improving database portability, security, and resilience. With the use of conditions, loops, and object-oriented principles like other programming languages, PL/SQL provides developers with greater control over database operations.
In 1995, the International Organisation for Standardisation (ISO) SQL/PSM standard became part of the first public version of PL/SQL specification. As an Oracle PL/SQL programmer, having the necessary skills to create and manage the network interface of PL/SQL packages following an organization’s needs and fundamental standards is critical. To ensure successful development, comprehensive knowledge of the latest trends and appropriate background is necessary to design efficient applications and databases for infrastructure. Oracle PL/SQL developers are in high demand across numerous industries such as web development and data science that employ Structured Query Language (SQL). Those having the required expertise in Oracle PL/SQL can find lucrative job opportunities at major companies like IBM, International Monetary Fund (IMF), Infosys, and Bank of America.
Get familiar with Oracle PL/SQL
Oracle SQL empowers database users and administrators to enhance their productivity and efficiency in managing databases. The language was developed to optimise investments made in Oracle Database by reducing time spent on administrative tasks. Oracle SQL is similar to other database languages, providing flexible, efficient transaction-processing capabilities and portability.
Distinguishing features of Oracle PL/SQL
PL/SQL is a powerful, scalable language designed for database-oriented programming that is easy to learn and portable. PL/SQL enables direct execution of SQL statements from within the language, eliminating the need to learn new application programming interfaces (APIs). Additionally, PL/SQL is a flexible language that can be used in many different contexts. It can break down complex processes into smaller, more manageable code segments, making it a popular choice for database development due to its numerous time-saving features. PL/SQL delivers various unique benefits that include:
Error ManagementPL/SQL integrates an inbuilt error-detection and comprehension system. Whenever an error is detected, PL/SQL will generate an exception similar to the C programming language, removing the requirement for extensive checks on every action.
Blocks:PL/SQL source code is composed of one or more blocks that arrange a set of related statements and declarations. DECLARE, EXCEPTION, BEGIN and END constitute the four parts of a block, signifying the beginning and end of each code segment. Statements can be nested inside one another, enabling the execution of multiple operations in a single block.
Packages:A package comprises a structured set of related PL/SQL elements such as types, variables, subprograms, cursors, constants, and exceptions that can be stored and accessed from various programs within a database. Packages provide a convenient means of logically grouping related PL/SQL elements and making them accessible for usage by multiple programs.
Triggers:In PL/SQL, a trigger is a predefined block of code that reacts to events that occur on stored data in a database.
Portability:The Oracle database can be installed on virtually any platform, and PL/SQL programs developed for it can run on any operating system.
High-Level Productivity:Similar to a programming language, PL/SQL enables reading, writing, and manipulation of database data.
Scalability:PL/SQL applications enhance scalability by shifting application processing to the database server.
Manageability:By maintaining only one instance of a specific subprogram on the data server, the administrative process is significantly streamlined. Multiple programs can utilise the same subprogram, and any changes made to the subprogram do not impact the operation of the dependent programs.
