All,
I am a beginner to learn Pl/ SQL.
How can I return either " Return Pl/SQL table" or "Return VARCHAR2"
simultaneously? The result is dependable on Count(Last_name)
condition.
Thanks,
The below is incomplete because I cannot understand the above
question.
===========================================================
create or replace function New_Rental(
P_last_name S_member.LAST_NAME%TYPE,
P_member_id S_member.Member_id%TYPE,
P_first_name S_member.FIRST_NAME%TYPE,
P_phone S_member.Phone%TYPE,
P_VALID_DATE In OUT Date)
Return VARCHAR2
Is
V_msg :='Expected due date is'||P_VALID_DATE;
Begin
If Count(Last_name)=1 then
Select VALID_DATE INTO P_VALID_DATEfrom S_memberWhere Last_Name:= P_Last_name;return 'Expected due date
is'||P_VALID_DATE;
ElSIF Count(Last_name)> 1 then
Select VALID_DATE INTO P_VALID_DATEfrom S_memberWhere Last_name:=P_last_name And Member_id:= P_member_id;return
'Expecteddue date is'||P_VALID_DATE||'Person's record as
follows:'||P_last_name,P_first_name, P_phone, P_member_id ;
Else Count(Last_name)=0
return 'This person needs to be registered as a member'
End If;
End New_Rental;
