SQLPlus input behavior: “When you type a statement and press Enter, SQLPlus finishes and executes it immediately.” Evaluate the accuracy of this claim.

Introduction / Context:
Understanding how SQLPlus terminates and executes statements is essential for accurate script execution. Unlike some shells where Enter triggers immediate action, SQLPlus requires a statement terminator or a specific execution command. This question asks whether pressing Enter alone executes the SQL.

Given Data / Assumptions:

• You are interacting with SQLPlus directly (not SQL Developer or another client).
• Standard terminators are used: semicolon (;) at the end of SQL statements, or a slash (/) on a line by itself to submit the current buffer (often used after PL/SQL blocks).
• The SQL buffer holds the current statement until it is executed or replaced.

Concept / Approach:
Pressing Enter simply starts a new line and does not execute the SQL in SQLPlus. Execution occurs when SQLPlus receives a recognized terminator. For typical SQL (SELECT, DDL, DML), a semicolon ends and submits the statement. For PL/SQL blocks (DECLARE…BEGIN…END;), the block ends with a semicolon and is executed when you enter a slash on a separate line. The slash instructs SQLPlus to send the current buffer to the database.

Step-by-Step Solution:

Verification / Alternative check:
Observe the SQL buffer behavior using LIST; you will see the text remains until you terminate and execute.

Why Other Options Are Wrong:

• “Correct” misstates SQLPlus behavior.
• AUTOCOMMIT affects transaction commits, not execution triggers.
• A lone slash on the same line is not a standard SQL terminator; it must be on a new line for PL/SQL.

Common Pitfalls:
Forgetting the slash after PL/SQL; assuming Enter executes; mixing SQLPlus with GUI client behaviors.

Final Answer:
Incorrect
