Question

我正在尝试使用NEWUID（）函数生成唯一数字，但由于语法可能存在错误，因此无法执行代码。

我该如何纠正呢？

谢谢。

代码对我来说没问题。您有Wat错误讯息吗？您能否进一步说明一下您使用的HANA版本？

我执行了以下类似的SQL代码，并且有效：

CREATE PROCEDURE GENERATINGN (IN p_docentryt NVARCHAR(50))
LANGUAGE SQLSCRIPT 
AS
BEGIN
SELECT cast("ItemCode" || '-' || NEWUID() as nvarchar(50)) AS "UNIQUEIDENTIFIER"
FROM (
  SELECT 'my-ItemCode' as "ItemCode" FROM DUMMY
);
END;

在HANA数据库中使用NEWUID（）函数
