Initialize the driver
Note

To connect to YDB, you need to specify the required and additional parameters that define the driver's behavior (learn more in Connecting to the YDB server).
Below are examples of the code for connecting to YDB (driver creation) in different YDB SDKs.
Go (native)
Go (database/sql)
Java
package main
import (
"context"
"os"
"github.com/ydb-platform/ydb-go-sdk/v3"
)
func main() {
db, err := ydb.Open(ctx, "grpc://localhost:2136/local")
if err != nil {
log.Fatal(err)
}
...
}
Using a connector (recommended)
package main
import (
"context"
"database/sql"
"os"
"github.com/ydb-platform/ydb-go-sdk/v3"
)
func main() {
ctx, cancel := context.WithCancel(context.Background())
defer cancel()
nativeDriver, err := ydb.Open(ctx,
os.Getenv("YDB_CONNECTION_STRING"),
)
if err != nil {
panic(err)
}
defer nativeDriver.Close(ctx)
connector, err := ydb.Connector(nativeDriver)
if err != nil {
panic(err)
}
db := sql.OpenDB(connector)
defer db.Close()
...
}
Using a connection string
The database/sql
driver is registered when importing the package of a specific driver separated by an underscore:
package main
import (
"context"
"database/sql"
"os"
_ "github.com/ydb-platform/ydb-go-sdk/v3"
)
func main() {
db, err := sql.Open("ydb", "grpc://localhost:2136/local")
if err != nil {
log.Fatal(err)
}
...
}
