下面语句怎么写的啊？？？？？？
if select count(1) from test3 where id = 2 >0
select 1 from dual
else
select 2 from dual
上面这句话报错，，请问用oracle怎么写的啊？
[解决办法]
试试这样写
DECLARE
rnt int := 0;
BEGIN
SELECT COUNT(1) INTO rnt FROM t_test ;
IF (rnt >0) THEN
--select 1 from dual;
dbms_output.put_line('aaaaaaa');
ELSE
--select 2 from dual;
dbms_output.put_line('bbbbbb');
END IF;
END;
