Hi Florian,
You are right, but using your code I've got the error:
Could not execute 'CALL PR_TEST_R_2(?)' in 210 ms 326 µs .
SAP DBTech JDBC: [2048]: column store error: search table error: [34086] Convert data error: Convert Data from R to NewDB failed.;Column 'RESULT0' not computed from R.
But, accordingly with R column name MUST be the same as HANA column name which are uppercase, so the right code is:
result0 <- data.frame(RESULT0=c("R"));
which works like a sharm !!!
Many thanks again.
Pierre
