Error handling: PL/SQL handles errors or exceptions effectively throughout the execution of a PL/SQL program.Better performance: PL/SQL engine processes multiple SQL statements at the same time as one block, thereby reducing network traffic.Procedural language capability: It consists of procedural language constructs like conditional statements (if else statements) and loops like (FOR loops).PL/SQL blocks are often keep within the info and reused. Each block forms a unit of a task or a logical module. Block structures: It consists of blocks of code, which can be nested within each other.Advantages of PL/SQL are as following below:
WHAT IS PL SQL DEVELOPER CODE
Stored procedures square measure units of procedural code keep during a compiled type inside the info.

PL/SQL is most helpful to put in writing triggers and keep procedures. if…then…else…) and iterative constructs (ie. It was developed by Oracle Corporation within the early 90’s to boost the capabilities of SQL. PL/SQL stands for “Procedural language extensions to SQL.” PL/SQL is a database-oriented programming language that extends SQL with procedural capabilities. PL/SQL is a block structured language that enables developers to combine the power of SQL with procedural statements.All the statements of a block are passed to oracle engine all at once which increases processing speed and decreases the traffic. SQL specifies what’s needed and not however it ought to be done.

Such porting could be required when the underlying DBMS needs to be upgraded or changed. It enables the systems personnel end-users to deal with a number of database management systems where it is available.SQL could be a high level language that has a larger degree of abstraction than procedural languages.Structured Query Language (SQL) is a standard Database language which is used to create, maintain and retrieve the relational database.
