FAQ

    What is SQL?
  • SQL (Structured Query Language) is a programming language used for managing and querying relational databases.
  • What is a database?
  • A database is an organized collection of structured information stored electronically, often managed using SQL.
  • What are SQL tables?
  • Tables are structures within a database that store data in rows and columns, similar to a spreadsheet.
  • What is a primary key in SQL?
  • A primary key is a unique identifier for each record in a table, ensuring no duplicate rows.
  • What are SQL queries?
  • SQL queries are commands used to retrieve, update, delete, or insert data into a database.
  • What is a JOIN in SQL?
  • JOIN is a SQL operation that combines rows from two or more tables based on a related column.
  • What is the difference between INNER JOIN and OUTER JOIN?
  • INNER JOIN returns only matching records between tables, while OUTER JOIN returns all records, including unmatched ones.
  • What are SQL data types?
  • SQL data types define the kind of data a column can hold, such as integers, text, dates, and booleans.
  • What is a stored procedure in SQL?
  • A stored procedure is a set of SQL statements stored in the database and executed as a program to perform specific tasks.
  • What is normalization in SQL?
  • Normalization organizes a database to reduce redundancy and improve data integrity through table structure design.
  • What is an index in SQL?
  • An index is a database structure that speeds up the retrieval of rows by creating a quick access path for data.
  • How do transactions work in SQL?
  • Transactions group SQL operations, ensuring that they either fully complete or are fully rolled back to maintain data consistency.
  • What is the difference between SQL and NoSQL?
  • SQL databases are structured and relational, while NoSQL databases are non-relational and better suited for unstructured data.
  • What are SQL aggregate functions?
  • Aggregate functions (e.g., COUNT, SUM, AVG) perform calculations on data across multiple rows to produce a single result.
  • What are common SQL commands?
  • Common SQL commands include SELECT, INSERT, UPDATE, DELETE, and CREATE, each serving different data management purposes.
