SQL Language Syntax
SQL (Structured Query Language) is a standard language for accessing and manipulating databases. It consists of various components such as statements, clauses, and expressions.
SELECT Statement:
SELECT column1, column2
FROM table_name
WHERE condition;The SELECT statement is used to retrieve data from a database.
INSERT INTO Statement:
INSERT INTO table_name (column1, column2)
VALUES (value1, value2);The INSERT INTO statement is used to insert new records into a database table.
UPDATE Statement:
UPDATE table_name
SET column1 = value1, column2 = value2
WHERE condition;The UPDATE statement is used to modify existing records in a database table.
DELETE Statement:
DELETE FROM table_name
WHERE condition;The DELETE statement is used to delete existing records from a database table.
These are some of the basic components of SQL language syntax. SQL also includes other components like clauses (e.g., WHERE, ORDER BY) and expressions (e.g., arithmetic expressions, string functions) for more advanced database operations.
