Where does hyperledger fabric store the database for the blockchain?

I have hyperledger fabric network setup on my local machine with a single validating node. I am developing a chaincode and would like to clear my blockchain. I have read that the hyperledger fabric stores the database under /var/hyperledger. However, I do not see this hyperledger directory under /var. Is there another location for this directory? My development platform is MAC and I am using docker-compose to start my hyperledger fabric network.

To clear the blockchain, the easiest way is to stop and run docker container again, given that you only have 1 validator peer you should not be worried about data consistency. Also, try to use the latest version of fabric releases since they improved a lot these kind of problems. And regarding the issue,

no rows in result set

make sure that youe have specified the right organization name and department when requesting user validation agains CA. The parameters you send, must exist on CA database, otherwise, you will receive that error.

The Hyperledger Fabric stores the database in /var/hyperledger/production/db within the file system for the validating peer. You can navigate to the validating peer file system by using a command like docker exec -it substitute_container_name bash. I am not aware of another location of the database. If the instructions at https://hub.docker.com/r/ibmblockchain/fabric-peer/ for using Hyperledger Docker images are followed, then the database location should be /var/hyperledger/production/db.
