In SQLPlus, which character terminates a statement so that it is executed when you press Enter?

Introduction / Context:
SQLPlus collects input lines until a statement terminator is encountered. Understanding terminators is necessary to run SQL and PL/SQL blocks properly.

Given Data / Assumptions:

• We are executing SQL statements interactively in SQLPlus.
• We need the character that ends the statement.

Concept / Approach:
Standard SQL statements are terminated with a semicolon in SQLPlus. PL/SQL blocks additionally use a slash (/) on a separate line to execute the compiled block after the ending semicolon of END;.

Step-by-Step Solution:

Verification / Alternative check:
SQLPlus help and examples consistently use ; to terminate SQL statements.

Why Other Options Are Wrong:
Slash (/) is used to execute the most recent PL/SQL block or the SQL buffer, not to end a single SQL statement line.
Colon and period are not SQL*Plus statement terminators.

Common Pitfalls:
Mixing PL/SQL block execution with single SQL statement execution; forgetting the final ; causes the client to wait for more input.

Final Answer:
A semicolon ( ; ) followed by Enter.
