v_q NUMBER;
CURSOR c1 IS
SELECT table_name tn FROM tabs;
TYPE c IS REF CURSOR;
c2 c;
BEGIN
DBMS_OUTPUT.PUT_LINE('以下为空数据表的表名:');
FOR r1 IN c1 LOOP
v_table :=r1.tn;
v_sql :='SELECT COUNT(*) q FROM '||v_table;
OPEN c2 FOR v_sql;
LOOP
FETCH c2 INTO v_q;
EXIT WHEN c2%NOTFOUND;
IF v_q=0 THEN
DBMS_OUTPUT.PUT_LINE(v_table);
END IF;
END LOOP;
CLOSE c2;
