What is SQL ?
The full form of SQL is Structured Query Language. Its S-Q-L or sometimes See-Quel is also read. It is a type of language used in database management.
Operations like create, insert, search, update, delete are performed on the database only through this query language.
For example, we have a table named student and we want to see the name of students whose age is less than 20 years, then its syntax would be something like this: SELECT name from students WHERE age <20 where “name” is a column Is the name of and “students” is the name of a table.
Different codes have been defined in SQL for each type of operation. Some code is written through this language and operations like insert, update, delete are performed in the database.
