我正在尝试在条件为TRUE时打印TEXT.选择代码完美正常.当我只运行选择代码时,它显示403值.但是当条件存在时我必须打印一些文本.以下代码有什么问题.
BEGIN
IF EXISTS(
SELECT CE.S_REGNO FROM
COURSEOFFERING CO
JOIN CO_ENROLMENT CE
ON CE.CO_ID = CO.CO_ID
WHERE CE.S_REGNO=403 AND CE.COE_COMPLETIONSTATUS = 'C' AND CO.C_ID = 803
)
THEN
DBMS_OUTPUT.put_line('YES YOU CAN');
END;
这是错误报告:
Error report:
