Difficulty: Easy
Correct Answer: SELECT
Explanation:
Introduction / Context:
Structured Query Language (SQL) provides a declarative interface for retrieving and manipulating relational data. The most frequently used operation is reading data for reports, screens, and analytics. Identifying the correct statement is foundational for anyone learning SQL.
Given Data / Assumptions:
Concept / Approach:
The SELECT statement retrieves data from one or more tables or views. It specifies the columns to project, the source tables, and optional clauses to filter, aggregate, and sort results. Other words like “CHOOSE,” “LIST,” or “BROWSE” are not SQL verbs, though user interfaces might use them informally.
Step-by-Step Solution:
Verification / Alternative check:
All mainstream RDBMSs (PostgreSQL, SQL Server, MySQL, Oracle) implement SELECT as the query verb for data retrieval.
Why Other Options Are Wrong:
Common Pitfalls:
Forgetting necessary filters causing large scans; misunderstanding JOIN semantics leading to duplicates; omitting ORDER BY and expecting deterministic order.
Final Answer:
SELECT
