开始
rowcount 并不是定义或open了cursor,就是固定的值，它随着每次fetch而累计：
--INDEX BY Table SET SERVEROUTPUT ON; DECLARE v_empno emp.empno%TYPE; v_ename emp.ename%TYPE; CURSOR emp_cursor IS SELECT empno,ename from emp where empno<>1000; BEGIN LOOP IF NOT emp_cursor%ISOPEN THEN OPEN emp_cursor; END IF; FETCH emp_cursor INTO v_empno,v_ename; EXIT WHEN emp_cursor%NOTFOUND; dbms_output.put_line(
'rowcount is:'|| emp_cursor%ROWCOUNT || '-- empno is:' || v_empno || '-- emp name is:' || v_ename); END LOOP; END; /
运行结果：
anonymous block completed rowcount is:1-- empno is:7369-- emp name is:SMITH rowcount is:2-- empno is:7499-- emp name is:ALLEN rowcount is:3-- empno is:7521-- emp name is:WARD rowcount is:4-- empno is:7566-- emp name is:JONES rowcount is:5-- empno is:7654-- emp name is:MARTIN rowcount is:6-- empno is:7698-- emp name is:BLAKE rowcount is:7-- empno is:7782-- emp name is:CLARK rowcount is:8-- empno is:7788-- emp name is:SCOTT rowcount is:9-- empno is:7839-- emp name is:KING rowcount is:10-- empno is:7844-- emp name is:TURNER rowcount is:11-- empno is:7876-- emp name is:ADAMS rowcount is:12-- empno is:7900-- emp name is:JAMES rowcount is:13-- empno is:7902-- emp name is:FORD rowcount is:14-- empno is:7934-- emp name is:MILLER
