_ "github.com/apache/calcite-avatica-go/v4"
"github.com/sirupsen/logrus"
)
const(
JDBC_DRIVER = "avatica"
PHOENIX_ADDR = "http://localhost:8765";
)
var db *sql.DB
func init(){
db, err := sql.Open(JDBC_DRIVER, PHOENIX_ADDR)
if err != nil {
logrus.Error("error connecting: %s", err.Error())
if err != nil {
logrus.Error("exec phoenix sql", query, err)
}
defer db.Close()
return res
}
func QueryContext(query string) (rows *sql.Rows) {
rows, err := db.QueryContext(context.TODO(), query)
if err != nil{
logrus.Error("query: ", query, err)
}
defer db.Close()
return rows
}
func main() {
logrus.Info(QueryContext("SELECT * FROM TEST"))
}
> when i use the example calcite-avatica-go provided, it always reports “panic:
> runtime error: invalid memory address or nil pointer dereference[signal
> SIGSEGV: segmentation violation code=0x1 addr=0x20 pc=0x4e6e01]”
