Implicit cursor attributes
Learn Implicit cursor attributes in PL/SQL through a focused explanation, a dedicated construct-specific example, an engineering boundary, and a mastery check.
Implicit cursor attributes is an atomic PL/SQL topic inside SQL in PL/SQL. This lesson focuses on how the Implicit cursor attributes construct is written, what it changes, and when it is the right tool.
Trace the example line by line. Identify the exact syntax for Implicit cursor attributes, the input state before it runs, and the resulting value, control flow, database state, hardware behavior, or runtime effect afterward. Neighboring lessons use different constructs rather than renamed copies of this one.
Topic-specific example
BEGIN DELETE FROM sessions WHERE expires_at<SYSDATE; IF SQL%FOUND THEN DBMS_OUTPUT.PUT_LINE(SQL%ROWCOUNT); END IF; END; /
For Implicit cursor attributes, test the boundary that belongs to this exact feature rather than a generic failure case. Check invalid or empty input, NULL/unknown state, numeric limits, transaction or exception behavior, synthesis/runtime constraints, ownership/permission rules, or backtracking/control-flow effects where they apply.
