问题 I am having issues with reading HANA data into R. I have established my connection via ch <- odbcConnect("HANA",uid="USER",pwd="PW") And confirmed I am connected via sqlTables(ch) which pulls up my list of tables. Filtering on my desired table I am trying to pull reveals the full name to be "ccf-edw.self-service.MDM::Q_CA_R_CUSTOMER_REPORTS" From other posts I have seen, there appear to be issues surrounding the periods.

问题 Is there an alternative in HANA sql for the "cross apply" operator as available in MsSql? Or is there a way to apply a function for values in a table? Something like select T.*, F.* from T cross join someFunction(T.Value) F 回答1: You can use the cross join in SAP HANA, that's not a problem.

问题 I am working with SAP HANA I would like to know if it is possible to get disk size of csv data with sql. The csv data that i mean is the file \index\SCHEMA NAME \CL\TABLE_NAME\data.csv after export. Best Regards Houssem 回答1: Nope, there is no way to generate this directly.\ You could, however, do some rough estimation, by looking at M_CS_COLUMNS to see the estimated uncompressed size for each column. Then you could add six bytes (double byte encoding) for every column * no. of records to

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
