Constants ¶
const ( DfvLevel0 int = 0 // base data format DfvLevel1 int = 1 // eval types support all data types DfvLevel2 int = 2 // reserved, broken, do not use DfvLevel3 int = 3 // additional types Longdate, Secondate, Daydate, Secondtime supported for NGAP DfvLevel4 int = 4 // generic support for new date/time types DfvLevel5 int = 5 // spatial types in ODBC on request DfvLevel6 int = 6 // BINTEXT DfvLevel7 int = 7 // with boolean support DfvLevel8 int = 8 // with FIXED8/12/16 support )
Data format version values.
const ( HDBFNone uint64 = 1 << iota HDBFServerVersion // HANA reports server version in connect options HDBFConnectClientInfo // HANA accepts ClientInfo as part of the connection process )
HDBVersion feature flags.
Variables ¶
SupportedDfvs returns a slice of data format versions supported by the driver.
Functions ¶
func IsSupportedDfv ¶ added in v0.104.0
IsSupportedDfv returns true if the data format version dfv is supported by the driver, false otherwise.
Types ¶
type DriverConn ¶ added in v0.104.0
type DriverConn interface {
ServerInfo() *ServerInfo
}
DriverConn enhances a connection with go-hdb specific connection functions.
type HDBVersion ¶
type HDBVersion struct {
// contains filtered or unexported fields
}
HDBVersion is representing a hdb version.
func ParseHDBVersion ¶
func ParseHDBVersion(s string) *HDBVersion
ParseHDBVersion parses a semantic hdb version string field.
func (HDBVersion) BuildID ¶
func (vn HDBVersion) BuildID() uint64
BuildID returns the build id field of a HDBVersionNumber.
func (*HDBVersion) Compare ¶
func (v *HDBVersion) Compare(v2 *HDBVersion) int
Compare compares the version with a second version v2. The result will be
0 in case the two versions are equal,
-1 in case version v has lower precedence than c2,
1 in case version v has higher precedence than c2.
func (*HDBVersion) HasFeature ¶
func (v *HDBVersion) HasFeature(feature uint64) bool
HasFeature returns true if HDBVersion does support feature - false otherwise.
func (HDBVersion) Major ¶
func (vn HDBVersion) Major() uint64
Major returns the major field of a hdbVersionNumber.
func (HDBVersion) Minor ¶
func (vn HDBVersion) Minor() uint64
Minor returns the minor field of a HDBVersionNumber.
func (HDBVersion) Patch ¶
func (vn HDBVersion) Patch() uint64
Patch returns the patch field of a HDBVersionNumber.
func (HDBVersion) Revision ¶
func (vn HDBVersion) Revision() uint64
Revision returns the revision field of a HDBVersionNumber.
type ServerInfo ¶
type ServerInfo struct {
Version *HDBVersion
}
ServerInfo contains hdb server information.
