SQL is a powerful, non-procedural database language used to build, maintain and retrieve relational databases. It allows end-users to interact with database management systems.
What is PL/SQL?
PL/SQL stands for Procedural Language extension to SQL. It is a procedural language that combines the power of SQL with procedural statements.
Comparison Based on Definition
While SQL is a structured language for querying and manipulating data stored in databases, PL/SQL is a procedural language used to implement SQL statements more efficiently.
Comparison Based on Operations
A SQL query performs only one operation at a time, while a PL/SQL block executes several operations as a single block, resulting in reduced network traffic.
Comparison Based on Data Variables
There is no support for data variables in SQL, whereas data types and constraints are supported in PL/SQL.
Comparison Based on Control Structures
SQL does not support control structures like if-else, For loop, and While loop, whereas PL/SQL does.
Comparison Based on Embed
Since PLSQL is an extension of SQL, SQL can be embedded in PLSQL syntax. But, PL/SQL cannot be embedded in SQL syntax.
Comparison Based on Usage
GitHub doesn't have milestones, whereas, GitLab uses milestones to keep track of problems and merge requests that have been generated to accomplish a larger target.
