Panic when select a column DECIMAL 18,2 about go-hdb

[stfnmllr]

Great - thanks a lot for the example!
The issue should be fixed with https://github.com/SAP/go-hdb/releases/tag/v0.102.2.

Please provide the example code selecting the DECIMAL, especially the Go variable definition for the Scan.

especially the Go variable definition for the Scan

The code panic before that.

A repro code:

package main

import (
	"database/sql"
	"fmt"
	"log"

	_ "github.com/SAP/go-hdb/driver"
)

func main() {
	// create dsn
	dsn := fmt.Sprintf("hdb://%s:%s@%s:%d", "username", "password", "host", 39013)

	// open db
	db, err := sql.Open("hdb", dsn)
	if err != nil {
		log.Print(err)
		return
	}

	err = db.Ping()
	if err != nil {
		log.Print(err)
		return
	}

	defer db.Close()

	// drop table if exists
	db.Exec(`drop table issue64`)

	// drop table at end for cleaning
	defer db.Exec(`drop table issue64`)

	// create the table
	_, err = db.Exec(`create table issue64 (a DECIMAL(18,2))`)
	if err != nil {
		log.Print(err)
		return
	}

	// select column types
	rows, err := db.Query(`select a from issue64`)
	if err != nil {
		log.Print(err)
		return
	}

	types, err := rows.ColumnTypes()
	if err != nil {
		panic(err)
	}
	for _, v := range types {
		log.Printf("%s", v.DatabaseTypeName())
	}

	// print success
	log.Print("success")
}
