我刚刚开始使用SAP HANA - 测试水。
我的第一步是在Eclipse Luna中打开一个SQL控制台，在SAP Business One演示数据库上运行一个简单的查询。
我发现＆＃34; SELECT * FROM OCRD＆＃34;工作正常，但是＆＃34; SELECT CardCode，CardName FROM OCRD＆＃34;导致无效的字段错误。
在字段名称周围加上双引号会导致工作查询。
我有以下问题：
1）SAP HANA示例均未表明查询中需要双引号。 2）我们有大约2000行要转换的T-SQL查询，如果我可以使用没有双引号的查询，那将是最好的。
双引号是语法，JDBC事物，SAP B1事物，Column Store事物还是Eclipse事物？
如何在不需要这样的引号的情况下运行查询？
感谢您帮助我正常运行。

答案 0 :(得分：2)
一般来说，你已经在评论中得到了答案。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 - 在某种程度上。不带引号的标识符基本上被转换为＆＃39;大写所以
CREATE COLUMN TABLE tab (id INT);
和
CREATE COLUMN TABLE "TAB" ("ID" INT);
基本相同。它也可以反过来。所以
CREATE COLUMN TABLE "TAB" ("ID" INT);
SELECT id FROM tab;
SELECT Id FROM Tab;
SELECT "ID" FROM "TAB";
然而，所有人都会工作
SELECT "Id" FROM "Tab";
不会。总结如下：
是的，a_horse_with_no_name非常正确，引用的标识符被视为区分大小写。但是，当创建全部大写时，即使被引用，您也不会一直需要使用引号。
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，它们会给你一个提示。如果它们都是大写的，则列基本上不区分大小写，否则您必须将具体情况与引号匹配。
