Trouble connecting to a remote HANA database via JDBC

由 女生的网名这么多〃 提交于 2019-12-06 12:18:39
问题 I'm running a small JAVA program from my laptop trying to connect via JDBC to our HANA server for a "Can we?" prototype. I understand it's possible to connect via JDBC connection to a remote HANA server. However, I cannot. Here's the methodology I'm using from the JAVA using the sapdbc.jar file. I'm just testing a connection here. DataSourceSapDB ds = new DataSourceSapDB(); ds.setServerName("10.x.x.xxx"); ds.setPort(30015); ds.setDatabaseName("dbNAME"); ds.setUser("myUser"); ds.setPassword(

问题 how do I cast a blob to varchar with SAP HANA database using SQL. (we need the column to be stored in blob - not TEXT - in else HANA automatically creates an index on this column.

[转帖]SSD和内存数据库技术

SSD和内存数据库技术 自己的理解还是不是很对 SSD 提升的是 随机读 并没有对顺序写有多大的提升, 因为数据库采用的是redo的模式. 理论上写入 时是顺序写 所以 写并发的提升不会很大 但是会很大的提升读取的速度. 2016-04-26 10:57:47 dingdingfish 阅读数 7650 更多 分类专栏： 内存数据库 In-Memory Computing Technology 版权声明：本文为博主原创文章，遵循 CC 4.0 BY-SA 版权协议，转载请附上原文出处链接和本声明。 本文链接： https://xiaoyu.blog.csdn.net/article/details/51248768 本文为阅读书籍 Next Generation Databases: NoSQL, NewSQL, and Big Data 第7章: The End of Disk?

问题 I am having an arraylist of objects and trying to insert the list into HANA. So my insert code looks like PreparedStatement stmt = conn .prepareStatement("INSERT INTO SCHEMA.TABLE VALUES" + " (?, ?, ?, ?, ?, ?, ?, ARRAY("+"1,2,3"+")"); for (int i = 1; i <= ITERATION_MAX; i++) { stmt.setInt(1, listofdata.get(i).get_id()); stmt.setInt(2, listofdata.get(i).get_name()); stmt.setInt(3, listofdata.get(i).get_place()); stmt.setInt(4, listofdata.get(i).get_year()); stmt.setInt(5, listofdata.get(i)

SQL capped, continuous sum

由 强颜欢笑 提交于 2019-12-03 20:53:38
Assume a time series where we have one value per point in time. I have to calculate a continues sum by calculating the current value + the sum of the previous value. Tricky part however is, that the sum should be capped and hence not exceed a certain value. Example: Sum is capped at +2. +-----+---------+------------+ | row | measure | capped sum | +-----+---------+------------+ | 1 | 1 | 1 | | 2 | 3 | 2 | | 3 | 4 | 2 | | 4 | -2 | 0 | | 5 | 1 | 1 | +-----+---------+------------+ e.g. the "capped sum" of row 4 is calulated using the "capped sum" from the previous row, "2", and adding the current

SAP HANA Authorisation Error: SAP DBTech JDBC: [258]: insufficient privilege: search table error: [2950] user is not authorized

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: At the moment I try to understand SAP HANAs authorisation concept. I assigned the analytic user the following rights: select on _SYS_BI, _SYS_BIC execute on REPOSITORY_REST root package: REPO_READ If I create an analytic privilege on an information view and assign this privilege to the user then the user is able to query the information view. On the other hand the modeller does not need this analytic privilege to query the information view. So there must be another way to allow the user to query the data - right? And I try to understand how.
