那些遇到过的问题

HANA新手，为什么我的字段名称需要引用？

Mar*_*ohn 3 sql hana eclipse-luna

我刚刚开始使用 SAP HANA - 试水。

我的第一步是在 Eclipse Luna 中打开 SQL 控制台，在 SAP Business One 演示数据库上运行简单的查询。

我发现“ SELECT * FROM OCRD”工作正常，但“ SELECT CardCode, CardName FROM OCRD”会导致无效字段错误。

在字段名称周围加上双引号会产生有效的查询。

我的担忧如下：

  1. SAP HANA 示例均未表明查询中需要使用双引号。
  2. 我们有大约 2000 行 T-SQL 查询需要转换，如果我可以使用不带双引号的查询，那就最好了。

双引号是语法问题、JDBC 问题、SAP B1 问题、列存储问题还是 Eclipse 问题？

如何在不需要此类引号的情况下运行查询？

感谢您为我的启动和运行提供的任何帮助。

一般来说，评论里你已经有了答案。在某种程度上，带引号的标识符区分大小写，不带引号的标识符不区分大小写。不带引号的标识符基本上被“转换”为大写。所以

CREATE COLUMN TABLE tab (id INT);
Run Code Online (Sandbox Code Playgroud)

和

CREATE COLUMN TABLE "TAB" ("ID" INT);
Run Code Online (Sandbox Code Playgroud)

基本相同。反之亦然。所以

CREATE COLUMN TABLE "TAB" ("ID" INT);
SELECT id FROM tab;
SELECT Id FROM Tab;
SELECT "ID" FROM "TAB";
Run Code Online (Sandbox Code Playgroud)

然而一切都会奏效

SELECT "Id" FROM "Tab";
Run Code Online (Sandbox Code Playgroud)

将不会。所以总结一下：

是的，a_horse_with_no_name 是非常正确的，带引号的标识符被视为区分大小写。但是，当创建时全部大写，即使引用时，您也不需要始终使用引号。

一个好的提示可能是查看 HANA Studio 在显示结果时显示的列标题，它们会给您提示。如果它们都是大写，则列基本上不区分大小写，否则您必须将确切的大小写与引号匹配。
