Go-hdb is a native Go (Golang) HANA database driver for Go's SQL package. It implements the "SAP HANA SQL Command Network Protocol".
For the official SAP HANA client Go support (not this database driver), please see SAP Help Portal.
go get -u github.com/SAP/go-hdb/driver
To build go-hdb, a working Go environment of the latest or second latest Go version is required.
API documentation and documented examples can be found at https://pkg.go.dev/github.com/SAP/go-hdb/driver.
The HANA cloud connection proxy uses SNI, which requires a TLS connection. By default, one can rely on the root certificate set provided by the host, which already comes with the necessary DigiCert certificates (CA, G5). For more information on Go TLS certificate handling, please see https://pkg.go.dev/crypto/tls#Config.
Assuming the HANA cloud 'endpoint' is "something.hanacloud.ondemand.com:443", the DSN should look as follows:
"hdb://<USER>:<PASSWORD>@something.hanacloud.ondemand.com:443?TLSServerName=something.hanacloud.ondemand.com"
where:
- TLSServerName: same as 'host'
If a specific root certificate (e.g. self-signed) is needed, the TLSRootCAFile DSN parameter must point to the location in the file system where the root certificate file in PEM format is stored.
To run the driver integration tests, a HANA Database server is required. The test user must have privileges to create database schemas.
Set the environment variable GOHDBDSN:
#linux example
export GOHDBDSN="hdb://user:password@host:port"
go test
Using the Go build tag 'unit', only the driver unit tests will be executed (no HANA Database server required):
go test --tags unit
- Native Go implementation — no C libraries, no CGO.
- Compliant with the Go database/sql package.
- UTF-8 to/from CESU-8 encoding for HANA Unicode types.
- HANA decimals as Go rational numbers via math/big.
- Large Object streaming.
- 'Bulk' query execution.
- Stored Procedures with table output parameters.
- Parameter free statements and queries via Execer and Queryer interfaces.
- TLS TCP connections.
- Little-endian (e.g. amd64) and big-endian (e.g. s390x) architecture support.
- Driver connector interface.
- PBKDF2 authentication as default, standard user/password as fallback.
- LDAP, client certificate (X509) and JWT (JSON Web Token) authentication.
- Prometheus collectors for driver and extended database statistics.
- Scanning database rows into Go structs.
- Please see go.mod.
