This article mainly introduces what is the difference between SQL and PLSQL, the article is very detailed, has a certain reference value, interested friends must read it!

Structured query language (SQL) is a standard database language for creating, maintaining and retrieving relational databases.

The advantages of SQL are:

SQL can be a high-level language with a greater degree of abstraction than a programming language.

It enables system personnel end users to handle many available database management systems.

Portability. This migration may be required when the underlying DBMS needs to be upgraded or changed.

SQL specifies what is required, but should not do so.

PL / SQL is a block structured language that enables developers to combine the power of SQL with procedural statements. All statements for the block are passed to the oracle engine at once, increasing processing speed and reducing traffic. PL / SQL stands for "process language extension of SQL."

PL / SQL is a database-oriented programming language, which uses process functions to extend SQL. It was developed by Oracle in the early 1990s to improve the functionality of SQL.

PL / SQL will be selective (i.e. if... Then... Else...) and iterative structures (that is, loops) are added to the SQL. PL / SQL is most useful for writing triggers and preserving procedures. The stored procedure square unit of measurement of the program code is retained during the compilation type within the information. The advantages of PL / SQL are:

Block structure: it consists of code blocks that can be nested within each other. Each block forms a unit of a task or logical module. PL / SQL blocks are usually retained in the information and reused.

Procedural language capabilities: it consists of procedural language constructs, such as conditional statements (if else statements) and loops (FOR loops).

Better performance: the PL / SQL engine can process multiple SQL statements as a block at the same time, thereby reducing network traffic.

Error handling: PL / SQL effectively handles errors or exceptions during the execution of PL / SQL programs.

Once an association exception is caught, a specific action can be taken according to the type of exception, or it can be displayed to the user through a message.

The difference between SQL and PLSQL:

SQLPLSQL is a database structured query language. It is a database programming language that uses SQL. Data variables not available. Data variables are available. There is no supported control structure. Control Structures available, For loop, While loop. Query performs a single operation. The PLSQL block executes an operation group with a single Bloack. SQL is a declarative language. PLSQL is a programming language. SQL can be embedded in PLSQL. PLSQL can be embedded in SQL. It interacts directly with the database server. It does not interact with the database server. It is a data-oriented language. It is an application-oriented language. It is used to write queries, DDL and DML statements. It is used to writing blocks, functions, process triggers and packages. The above is all the content of what is the difference between SQL and PLSQL. Thank you for reading!
