You should be able to create a shell script execute as cron job or script the set of sql statements or call procedure in a file and execute it as a cron job calling hdbsql
syntax:
hdbsql -n <server>:<port> -i <sys no> -u <username> -p <password> -C <command separator> -I <file name>
Please note that using <password> is not recommended as you will have the password flying around in clear text instead it is highly recommended to use hdbstore
Further formation on usage of hdbsql can be found in HANA administrator guide
