SQL for Beginners for Software Development FAQs

1. What is the difference between WHERE and HAVING clauses in SQL queries?
Ans. WHERE filters rows before grouping data, while HAVING filters rows after aggregation. WHERE works with individual records and conditions like column comparisons, whereas HAVING operates on grouped results and aggregate functions such as COUNT, SUM, or AVG. Use WHERE for pre-filtering and HAVING for post-group filtering.
2. How do I write a SQL JOIN query to combine data from two tables?
Ans. A JOIN query links two tables using a common column. Syntax: SELECT columns FROM table1 JOIN table2 ON table1.id = table2.id. Four types exist: INNER JOIN (matching records only), LEFT JOIN (all left table rows), RIGHT JOIN (all right table rows), and FULL OUTER JOIN (all rows from both tables). Choose based on which data you need.
3. What are the main differences between UNION and UNION ALL in SQL?
Ans. UNION combines results from multiple queries and removes duplicate rows automatically, while UNION ALL keeps all rows including duplicates. UNION processes slower due to duplicate elimination overhead. Use UNION when duplicates matter to remove, and UNION ALL for faster performance when duplicates are acceptable or expected from different datasets.
4. How do I use GROUP BY with aggregate functions to summarize data?
Ans. GROUP BY organizes rows into groups by column values, then aggregate functions like COUNT, SUM, AVG, MIN, or MAX calculate summary statistics per group. Example: SELECT category, COUNT(*) FROM products GROUP BY category counts products by category. Combine with WHERE to filter rows before grouping and HAVING to filter groups after aggregation.
5. What is the purpose of indexes in SQL database performance?
Ans. Indexes speed up data retrieval by creating a sorted reference structure, reducing query execution time significantly. They work like book indices-directing the database to relevant rows without scanning entire tables. Primary indexes enforce uniqueness; secondary indexes optimize search speed. Trade-off: faster queries but slower insertions and updates, plus increased storage requirements.
6. How do I use subqueries and nested SELECT statements in SQL?
Ans. Subqueries are SELECT statements inside another query, returning data that the outer query uses. They appear in WHERE clauses (scalar subqueries returning one value), FROM clauses (derived tables), or IN operators (checking membership). Example: SELECT * FROM employees WHERE salary > (SELECT AVG(salary) FROM employees) finds above-average earners efficiently.
7. What are the different types of SQL constraints and how do I apply them?
Ans. SQL constraints enforce data integrity rules. PRIMARY KEY ensures uniqueness and non-null values; FOREIGN KEY links tables maintaining referential integrity; UNIQUE enforces distinct column values; NOT NULL requires data entry; CHECK validates conditions; DEFAULT assigns automatic values. Apply constraints during table creation: CREATE TABLE users (id INT PRIMARY KEY, email VARCHAR UNIQUE NOT NULL).
8. How do I handle NULL values in SQL queries with functions?
Ans. NULL represents missing data and requires special handling. Use IS NULL or IS NOT NULL operators for testing. Functions like COALESCE replace NULLs with alternatives: COALESCE(column, 'default') substitutes 'default' if column is NULL. IFNULL (MySQL) and NVL (Oracle) serve similar purposes. ISNULL checks existence but doesn't filter like comparison operators do.
9. What is the difference between DELETE, DROP, and TRUNCATE statements in SQL?
Ans. DELETE removes specific rows using WHERE conditions, maintaining table structure and logging transactions. DROP removes entire tables including schema and triggers permanently. TRUNCATE deletes all rows instantly without WHERE clause, faster than DELETE but cannot be rolled back in some databases. Use DELETE for selective removal, TRUNCATE for bulk clearing, DROP for removing structures entirely.
10. How do I create and modify tables using CREATE TABLE and ALTER TABLE commands?
Ans. CREATE TABLE defines new tables with column names, data types, and constraints: CREATE TABLE users (id INT PRIMARY KEY, name VARCHAR(50) NOT NULL). ALTER TABLE modifies existing structures: ALTER TABLE users ADD email VARCHAR(100), ALTER TABLE users DROP COLUMN age, or ALTER TABLE users MODIFY name VARCHAR(100). Both commands require proper syntax for schema changes.
