Basic SQL Queries
3 Topics
1
SELECT, FROM, and WHERE Clauses
The foundation of data query operations.
SELECT, FROM, and WHERE are tested in every SQL interview round. Interviewers evaluate your ability to write correct filters, understand NULL handling, and avoid common WHERE clause mistakes.
2
ORDER BY, LIMIT, and OFFSET Clauses
Sorting and paginating dataset query results.
Pagination queries with LIMIT/OFFSET are frequently tested in interviews. Interviewers check if you understand the performance implications of large offsets and know alternative pagination strategies.
3
DISTINCT and ALIAS Clauses
Removing duplicates and aliasing column/table names.
DISTINCT and aliasing are tested in SQL interviews to evaluate whether candidates understand result set deduplication, query readability, and the performance cost of DISTINCT operations.
