Pl/SQL函数不返回所有字段

Question

我有下面的函数，它工作正常。唯一的问题是它只返回从BODY的价值OF V_KPI_NAME。正如你所看到的，我也通过IN_ALERT_LOGS_TIMESTAMP,V_KPI_TPE，但它没有返回这些值。

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; 

Answer 1

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) ; 

每一个你将要覆盖的对象。

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) ;
