Pl/SQL Courses

PL/SQL is an abbreviation for "Procedural Language extensions to the Structured Query Language," a feature of the Oracle database. SQL is the standard language used for both querying and updating the data in all relational database management systems, including Oracle. PL/SQL adds more functionality to the SQL language by executing procedural programming in the database using functions, loops, and other constructs not available in SQL. PL/SQL is a programming language embedded in the Oracle database—not designed to be a standalone language. Because PL/SQL is a compiled language, interacts directly with the database, and already comes with Oracle, it is easier to write quicker running, more efficient code than with an external language like Java, C#, or C++. The PL/SQL engine in Oracle works with Oracle SQL to compile and execute the database code.

Having Oracle PL/SQL skills prepares you for many job opportunities with companies that use Oracle's database since PL/SQL is a proprietary programming language. An Oracle database administrator will most likely use PL/SQL every day, building procedures and functions that get stored in the database for more advanced ways of querying and transforming data stored there. Oracle database developers also need to know PL/SQL since this procedural programming feature is one of the main reasons a company chooses Oracle for solutions. Software engineers and web developers may need to know Oracle PL/SQL when their applications need to connect to an Oracle database to prepare data before they retrieve it. Data scientists will also benefit from PL/SQL if they interact with Oracle databases often because of the power it can add to their queries. Business analysts may also need to know the language when they use Oracle databases.
