RETURNING INTO
Learn RETURNING INTO in Oracle SQL through the exact construct, a dedicated example, a boundary case, and a mastery check.
RETURNING INTO is an atomic Oracle SQL lesson inside DML & Transactions. The example uses the specific syntax, command, API, instruction, or language rule named by this lesson.
Study the construct itself, then change one relevant input and predict the result before running it. That keeps this lesson focused on RETURNING INTO rather than on generic Oracle SQL syntax.
Topic-specific example
DECLARE v_id NUMBER; BEGIN INSERT INTO users(email) VALUES('a@example.com') RETURNING id INTO v_id; END;
Test RETURNING INTO with an empty result, NULL/missing value, duplicate key, or concurrent operation where relevant; database behavior should be verified at the boundary shown by this example.
