连接 HANA 数据库中的两列

Question

请给我一个建议，将下面的 MSSQL VIEW 转换为 HANA VIEW

CREATE VIEW [dbo].[ViewSample]
AS
SELECT [column1] + ' / ' + [cloumn2] AS CollectionLabel
FROM [dbo].[T1] T1
CROSS JOIN [dbo].[T2] T2

提前致谢

Answer 1

CONCAT两次怎么样？

CREATE VIEW "dbo"."ViewSample"
    AS
    SELECT CONCAT("column1", CONCAT(' / ', "cloumn2")) AS CollectionLabel
    FROM "dbo"."T1" T1
    CROSS JOIN "dbo"."T2" T2

Answer 2

还有一个 concat 运算符可以让你这样做 (||)

CREATE VIEW "dbo"."ViewSample"
    AS
    SELECT "column1" || ' / ' || "cloumn2" AS CollectionLabel
    FROM "dbo"."T1" T1
    CROSS JOIN "dbo"."T2" T2

Answer 3

只需使用“||”连接字符串和列。

假设您需要一个人的全名，并且在您的 table 中有两列，即 NAME 和 LAST_NAME。

SELECT NAME||' '||LAST_NAME FROM myTable
