Here are some common SQL interview questions with their answers to help you prepare effectively:
SQL stands for Structured Query Language, and it is used to communicate with relational databases to perform tasks like retrieving, inserting, updating, and deleting data.
SQL statements are classified into:
A primary key is a column or a combination of columns in a table that uniquely identifies each row. It cannot have duplicate or NULL values.
A foreign key is a column in a table that creates a relationship between two tables. It references the primary key of another table, ensuring referential integrity.
JOINS are used to combine rows from two or more tables based on a related column. Types:
A stored procedure is a precompiled collection of SQL statements stored in the database. It can be executed as needed to perform specific tasks, improving reusability and performance.
An index is a database object that improves the speed of data retrieval. It acts as a pointer to data in a table. However, indexes slow down write operations like INSERT, UPDATE, and DELETE.
A transaction is a sequence of operations performed as a single unit of work. Transactions ensure data integrity using properties called ACID (Atomicity, Consistency, Isolation, Durability). Example:
BEGIN TRANSACTION;
UPDATE accounts SET balance = balance - 100 WHERE account_id = 1;
UPDATE accounts SET balance = balance + 100 WHERE account_id = 2;
COMMIT;
