Issues connecting R to HANA db with many special characters

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.

Attempting

sqlQuery(ch, 'SELECT TOP 10 FROM "_SYS_BIC"."ccf-edw"."self-service"."MDM::Q_CA_R_CUSTOMER_REPORTS"')

Returns error

[1] "42000 257 [SAP AG][LIBODBCHDB DLL][HDBODBC] Syntax error or access violation;257 sql syntax error: incorrect syntax near \"FROM\": line 1 col 15 (at pos 15)"
[2] "[RODBC] ERROR: Could not SQLExecDirect 'SELECT TOP 10 FROM \"_SYS_BIC\".\"ccf-edw\".\"self-service\".\"MDM::Q_CA_R_CUSTOMER_REPORTS\"'" 

I am unsure exactly where to stick additional double quotes.

回答1:

Can you try this instead:

sqlQuery(ch, 'SELECT TOP 10 FROM "_SYS_BIC"."ccf-edw.self-service.MDM::Q_CA_R_CUSTOMER_REPORTS"')
