The emp table data is as follows
Define the object type
create or replace type typeof_userinfo_row as object(
user_id varchar2(50),
user_name varchar2(50)
)
Create a function with this type as the return value type
create or replace function FUN_TEST
return typeof_userinfo_row
is
FunctionResult typeof_userinfo_row;
begin
FunctionResult:=typeof_userinfo_row(null,null);
--将单条数据值插入到自定义类型的变量中
SELECT e.empno,e.ename INTO FunctionResult.user_id,FunctionResult.user_name
FROM emp e where e.empno = '7499';
RETURN(FunctionResult);
end FUN_TEST;
Call the function and print the execution result
declare res typeof_userinfo_row;
begin
res := FUN_TEST();
dbms_output.put_line(res.user_id || ' ' || res.user_name);
end;
