Introduction to PL/SQL Job Support:
PL/SQL Job Support atIDESTRAININGS. PL/SQL is an embrace SQL statements within its syntax to procedural language designed specifically. Compiled by the Oracle Database server are PL/SQL program units and are stored inside the database. Both PL/SQL and SQL run within the same server process, bringing optimal efficiency and at run-time. IDESTRAININGS provides the PL SQL expert consultant to guide you to finish the tasks at your job. Our consultants are real-time working professionals who have tremendous knowledge of various IT technologies. Before going to know more about On Job Support services, let’s have a look at some of the basic topics of PL SQL
Overview of PL SQL Job Support:
The PL/SQL programming language was developed by Oracle Corporation in the late 1980s as procedural extension language for SQL and the Oracle relational database.
- PL/SQL is a completely portable, high-performance transaction-processing language.
- PL/SQL provides a built-in, interpreted and OS independent programming environment.
- PL/SQL can also directly be called from the command-line SQL*Plus interface.
- Direct call can also be made from external programming language calls to database.
- PL/SQL’s general syntax is based on that of ADA and Pascal programming language.
- Apart from Oracle, PL/SQL is available in TimesTen in-memory database and IBM DB2.
PL/SQL Functionalities:
PL/SQL includes procedural language elements like conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variable of those types and triggers. It can support Array and handle exceptions (runtime errors). After the implementation of version 8 of Oracle database have included features associated with object orientation. You can create PL/SQL units like procedures, functions, packages, types and triggers, etc. which are stored in the database for reuse by applications. With PL/SQL, you can use SQL statements to manipulate Oracle data and flow of control statements to process the data. The PL/SQL is known for its combination of data manipulating power of SQL with data processing power of procedural languages. It inherits the robustness, security, and portability of the Oracle Database. PL/SQL is not case sensitive so you are free to use lower case letters or upper case letters except within string and character literals. A line of PL/SQL text contains groups of characters known as lexical units. It can be classified as follows:
- Delimeters
- Identifiers
- Literals
- Comments

PL/SQL has the following advantages −
- SQL is the standard database language and PL/SQL is strongly integrated with SQL. PL/SQL supports both static and dynamic SQL. Static SQL supports DML operations and transaction control from PL/SQL block. In Dynamic SQL, SQL allows embedding DDL statements in PL/SQL blocks.
- PL/SQL allows sending an entire block of statements to the database at one time. This reduces network traffic and provides high performance for the applications.
- PL/SQL gives high productivity to programmers as it can query, transform, and update data in a database.
- PL/SQL saves time on design and debugging by strong features, such as exception handling, encapsulation, data hiding, and object-oriented data types.
- Applications written in PL/SQL are fully portable.
- PL/SQL provides high security level.
- PL/SQL provides access to predefined SQL packages.
- PL/SQL provides support for Object-Oriented Programming.
- PL/SQL provides support for developing Web Applications and Server Pages.
- At virtual Job Support we also provide Job Support for Oracle PL SQL Job Support from our real-time consultants.
