Pl/SQL函数不返回所有字段

我有下面的功能，这是工作良好。唯一的问题是它只从

正文

返回

V\u KPI\u NAME

的值。正如您所看到的，我也在\u ALERT\u LOGS\u TIMESTAMP中传递

，
V\u KPI\u TPE
，但它不返回这些值

FUNCTION BUILD_ALERT_EMAIL_BODY
(
  IN_ALERT_LOGS_TIMESTAMP IN TIMESTAMP
, IN_ALERT_LOGS_LOG_DESC IN VARCHAR2
, IN_KPI_LOG_ID IN NUMBER
) RETURN VARCHAR2 AS
BODY VARCHAR2(4000) := '';
V_KPI_DEF_ID NUMBER;
V_KPI_NAME VARCHAR2(100);
V_KPI_DESC VARCHAR2(500);
V_KPI_TYPE VARCHAR2(100);
BEGIN
-- ,'yyyy-MM-dd H24 mm ss'
Select KPI_DEF_ID INTO V_KPI_DEF_ID FROM KPI_LOGS WHERE KPI_LOG_ID = IN_KPI_LOG_ID;


Select NAME INTO V_KPI_TYPE FROM RATOR_MONITORING_CONFIGURATION.KPI_DEFINITION KD JOIN RATOR_MONITORING_CONFIGURATION.KPI_TYPE KT ON KD.KPI_TYPE = KT.KPI_TYPE_ID WHERE KD.KPI_DEF_ID = V_KPI_DEF_ID;
Select KPI_NAME INTO V_KPI_NAME FROM RATOR_MONITORING_CONFIGURATION.KPI_DEFINITION WHERE KPI_DEF_ID = V_KPI_DEF_ID;
Select KPI_DESC INTO V_KPI_DESC FROM RATOR_MONITORING_CONFIGURATION.KPI_DEFINITION WHERE KPI_DEF_ID = V_KPI_DEF_ID;

  BODY := to_char(IN_ALERT_LOGS_TIMESTAMP,'DD.MM.YYYY HH24:MI') || Chr(13);
  BODY := V_KPI_NAME || Chr(13) ;
  BODY := V_KPI_TYPE || Chr(13) ;

  RETURN BODY;
END BUILD_ALERT_EMAIL_BODY;

您的每个文件都将覆盖对象

BODY := to_char(IN_ALERT_LOGS_TIMESTAMP,'DD.MM.YYYY HH24:MI') || Chr(13);
BODY := BODY || V_KPI_NAME || Chr(13) ;
BODY := BODY || V_KPI_TYPE || Chr(13) ;

哦，这很有效，我想在每个体值和每个体值之间加上分号，因为现在我得到的是一致的体值，没有空格。好吧，我相信你可以在需要的地方连接适当的值！
BODY := to_char(IN_ALERT_LOGS_TIMESTAMP,'DD.MM.YYYY HH24:MI') || Chr(13);
BODY := BODY || V_KPI_NAME || Chr(13) ;
BODY := BODY || V_KPI_TYPE || Chr(13) ;
