PL/ SQL Block - Shikshaglobe

PL/SQL is a procedural language extension to SQL. It has been developed by Oracle Corporation in the early 1990s to enhance the capabilities of SQL. PL/SQL includes procedural language elements such as conditions and loops. It also allows developers to define their own functions and procedures. PL/SQL code can be stored in the database and executed on the server.PL/SQL is a procedural language extension to SQL. It has been developed by Oracle Corporation in the early 1990s to enhance the capabilities of SQL. PL/SQL is one of three languages embedded in the Oracle Database, along with SQL and Java.PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). cursors (database objects used to iterate over a result set) and packages (schema objects that group logically related PL/SQL types, variables, constants, procedures, functions, and cursors).PL/SQL is a procedural language extension to SQL. It was developed by Oracle Corporation in the early 1990s to extend the functionality of SQL. PL/SQL is used in a wide range of applications, from small scripts to large enterprise applicationsA PL/SQL block is a set of related statements that are executed together as a unit. A PL/SQL block can be anonymous or stored in the database as a named object. A PL/SQL block typically contains one or more SQL statements,declarations, and executable statements.PL/SQL is a procedural language extension to SQL. It is used in Oracle Database and offers many features that are not available in standard SQL, such as looping and complex conditional logic. PL/SQL also has better error handling than SQL.A PL/SQL block consists of a header, a declaration section, an executable section, and an exception handling section. The header begins with the keyword DECLARE, followed by a list of declarations. The executable section contains one or more PL/SQL statements. The exception handling section contains one or more handlers for exceptions that might be raised in the executable section.
