Frequently asked questions about SQL

• What is the primary key in SQL?
  A primary key is a unique identifier for each record in a table. It ensures that every row in the table contains a distinct and non-null value in the primary key column. Primary keys are essential for enforcing data integrity and establishing relationships between tables.

• What is a constraint in SQL? Name a few.
  A constraint in SQL is a crucial rule that governs the data in a table, ensuring that the information remains accurate and reliable. Among the most essential constraints are:

  – PRIMARY KEY: This guarantees that every value in a designated column is unique, eliminating duplicates.

  – FOREIGN KEY: This maintains referential integrity, connecting tables and ensuring consistent relationships between them.

  – UNIQUE: This constraint safeguards against duplicate values in a column, promoting data integrity.

  – CHECK: This specifies conditions that data must be fulfilled before insertion or updates, enhancing data validation.

  – NOT NULL: This ensures that crucial columns cannot contain NULL values, promoting completeness of data.

• What is the view in SQL?
  In SQL, a view is a virtual table that is derived from the result set of an SQL statement. A view consists of rows and columns similar to a real table. The fields in a view are taken from one or more actual tables within the database.

• What is the trigger in SQL?
  A trigger in SQL is a predefined sequence of actions that automatically execute when a specific event occurs, such as when an INSERT or DELETE operation is performed on a table. Triggers are used to ensure data consistency, conduct auditing, and simplify various tasks.

•  What are aggregate functions? Can you name a few?
  Aggregate function in SQL performs calculations on a set of values and return a single result.
  • MIN() – returns the smallest value within the selected column.
  • MAX() – returns the largest value within the selected column.
  • COUNT() – returns the number of rows in a set.
  • SUM() – returns the total sum of a numerical column.
  • AVG() – returns the average value of a numerical column.

Pros and Cons of SQL

SQL (Structured Query Language) is widely used for managing relational databases.

Pros of SQL:

Easy to Learn and Use

• SQL uses simple and readable syntax (e.g., SELECT * FROM table_name;), making it accessible for beginners and professionals.

Powerful and Efficient

• SQL allows complex queries to retrieve, manipulate, and manage large amounts of data efficiently.

Data Integrity and Security

• SQL databases support constraints (e.g., PRIMARY KEY, FOREIGN KEY, UNIQUE, NOT NULL) that enforce data integrity.

Cons of SQL:

Scalability Limitations

• Traditional SQL databases struggle with horizontal scaling (adding more servers) compared to NoSQL databases like MongoDB.

Expensive for Enterprise Solutions

• Some SQL-based systems (e.g., Oracle, SQL Server) require costly licensing and maintenance.

Performance Issues with Large Joins

• Complex queries with multiple joins can slow down performance if not optimized properly.

Frequently asked questions (FAQ)

• What is a subquery?
  A SQL subquery, also referred to as a nested query or inner query, is a query that exists within another SQL statement. It enables you to use the result of one query as input for another query. Subqueries are enclosed in parentheses and can be employed in various parts of a SQL statement, including the SELECT, FROM, and WHERE clauses.

• What are indexes and types?
  Indexing is a valuable technique that optimizes search times in database queries. The structure of database indexing includes a search key and a pointer. There are four types of indexing: Primary, Secondary, Clustering, and Multivalued Indexing. Primary indexing itself is divided into two categories: dense indexing and sparse indexing.

• What is the difference between a function and a stored procedure?
  Triggers are unique stored procedures that run automatically in response to database events; functions are named operations that return a single value or a table; and stored procedures are reusable sets of SQL statements that can accept arguments and produce results.

• What is the primary key in SQL?
  Each row in a table is usually uniquely identified by values contained in a column or combination of columns. The table’s entity integrity is maintained by this column, or columns, which are referred to as the primary key (PK).

• List the different types of relationships in SQL.?
  There are three types of relationships between the data you are likely to encounter at this stage in the design: one-to-one, one-to-many, and many-to-many. To be able to identify these relationships, you need to examine the data and have an understanding of what business rules apply to the data and tables.
