使用if else语句显示过程mysql中的SET变量

Question

如何在表的过程中显示变量SET HasilBKD？
表中仅显示别名，例如（AS Syt_Pendidikan，Pendidikan_Prodi等...）。
但是if和else中的变量（HasilBKD）没有出现。
请帮助我该如何解决？ 这样的表格中的数据，但没有 HasilBKD 。
这是示例表。

这是代码：

CREATE DEFINER=`root`@`localhost` PROCEDURE 
`hasil_approval_verifikator`(nip varchar(30))
BEGIN
  DECLARE Pendidikan FLOAT;
  DECLARE Penelitian FLOAT;
  DECLARE Pengabdian FLOAT;
  DECLARE Penunjang FLOAT;
  DECLARE Points FLOAT;
  DECLARE SumBKD FLOAT;
  DECLARE SyaratBKD FLOAT;
  DECLARE HasilBKD varchar(30);
