Can “SELECT” clause be used without the clause “FROM”? YESNODEPENDSNone of the mentioned

Break Down the Problem

1. Understanding the question regarding SQL query structure.
2. Identifying the role of the SELECT and FROM clauses in an SQL statement.
3. Evaluating the possible options for the answer.

Relevant Concepts

• In SQL, the SELECT clause is used to specify the columns that you want to retrieve from a database.
• The FROM clause specifies the table from which to select the data.
• An SQL query typically requires both clauses to function correctly.

Analysis and Detail

1. The SELECT clause can technically be executed without a FROM clause when using specific functions or constants.
   • For example, a simple query like SELECT 1; is valid and does not require a table to select from.
2. However, in most practical scenarios, using SELECT without FROM is not common as it generally implies retrieving data from a specified source.

Verify and Summarize

• The correct answer to the question depends on the context in which SELECT is used.
• While SELECT can be used without FROM, it might not align with typical use cases in database queries.

Final Answer

DEPENDS: The SELECT clause can be used without the FROM clause in specific situations, such as when selecting constants or expressions, but it is not common in standard SQL queries.
