What is structured query language (a relational database language) and what is the SELECT statement used for?

• A. Structured Query Language is a language for managing relational databases; SELECT creates tables.
• B. Structured Query Language manages relational databases; SELECT inserts rows.
• C. Structured Query Language is a language for managing relational databases; SELECT retrieves data from tables.
• D. Structured Query Language is used for editing images; SELECT prints reports.

Answer: (C)

Structured Query Language is the standard tool for managing relational databases. The SELECT statement is used to retrieve data from tables, allowing you to choose which columns to return and which rows to include (with filters) or to combine data from multiple tables. This matches the choice that describes SQL as a language for managing relational databases and SELECT as retrieving data from tables. Other options misstate what SELECT does—creating tables is done with CREATE TABLE, inserting rows with INSERT, and SQL isn’t used for editing images (and printing reports is not a direct function of SQL, though it can supply data for a report).
