In the anonymous block, prefix each host variable name with a colon (:) to distinguish it from a PL/SQL collection variable name.

For each invocation of an ADT method, PL/SQL copies every attribute of the ADT. If the function is deterministic, specify the The data type of the value that a pipelined table function returns must be a collection type defined either at schema level or inside a package (therefore, it cannot be an associative array type).

Example 12-5 Nested Query Improves Performance In this example, the two queries produce the same result set, but the second query is more efficient than the first.

EXTEND(49999, 1); -- Copy element 1 into 2..50000 get_time(t1); do_nothing1(emp_tab); -- Pass IN OUT parameter get_time(t2); do_nothing2(emp_tab); -- Pass IN OUT NOCOPY parameter get_time(t3); DBMS_OUTPUT. PUT_LINE ('With NOCOPY: ' || TO_CHAR((t3 - t2))/100.0); END; / Because PL/SQL applications are often built around loops, it is important to optimize both the loops themselves and the code inside them. PUT_LINE('numbers1(' || j || ') = ' || numbers1(j)); END LOOP; DBMS_OUTPUT. However, the SQL optimizer does not optimize across PL/SQL statements.

If you must loop through a result set more than once, or issue other queries as you loop through a result set, you might be able to change the original query to give you exactly the results you want. Therefore, in Example 12-31, the first PL/SQL statement is slower than the second—despite the overhead of running two SQL statements in the second PL/SQL statement, and even if function results are piped between the two SQL statements in the first PL/SQL statement.

Subprogram inlining replaces a subprogram invocation with a copy of the invoked subprogram (if the invoked and invoking subprograms are in the same program unit).
