SQL queries act as statements that are run over the database. But the technical world needs various functionalities altogether in order to work with a large amounts of data. PL / SQL is also one of them.

PL / SQL means procedural language/structured query language. This is an extension of SQL. As the name suggests, it writes an SQL program in a procedural format. It is the highly structured language. SQL helps us run one action at a time in the database simultaneously. But what if one wants to do different actions together? Then we will need a certain type of pattern.

PL / SQL is programming in Pattern. It is an essential member of the Oracle Programming tool set and is used to encode programming by the server, SQL programming. PL / SQL is also a non-sensitive registry language such as SQL.

It extends SQL by adding constructs found in another procedural language, such as variables, a structure of control as if otherwise, cycles, a procedure, a function, and more advanced programming functions such as cursors, triggers, exception handling. PL / SQL programming is performed in the block structure.

  8. It Supports for Rising Web Applications and Pages.

Disadvantages of PL/SQL

PL / SQL loses its importance with the fact that, SQL is enough to run the program, with as many steps possible and work precisely.
