这个MySQL存储过程中的语法错误在哪里? [英] Where is the syntax error in this MySQL stored procedure?

问题描述

我想将输出参数名称设置为串联的kund.Vorname和kund.Nachname.但是我遇到语法错误，但找不到.我将不胜感激.

I want to set the output parameter name to the concatenated kund.Vorname and kund.Nachname. But I get a syntax error and I can't find it. I'd appreciate any help.

CREATE PROCEDURE GetName(IN kartennummer CHAR(16), OUT name VARCHAR(91))
BEGIN
SELECT @name = (CONCAT_WS(' ', kund.Vorname, kund.Nachname)
  FROM Kunden kund,
       Konten kont
  WHERE kund.KundenID = kont.KundenID AND
        kont.Kartennummer = kartennummer));
END;

推荐答案

而且，根据上下文，您可能需要 DELIMITER 语句.

And, depending on context, you may need a DELIMITER statement.
