Golang框架如何集成IBM DB2数据库？

go get github.com/ibmdb/go_ibm_db/api

import (
    "context"
    "database/sql"

    ibmdb "github.com/ibmdb/go_ibm_db/api"
)

func ConnectDB2() (*sql.DB, error) {
    connectionString := "Database=SAMPLE;Hostname=localhost;Port=50000;Protocol=TCPIP;UID=db2inst1;PWD=db2inst1"
    conn, err := ibmdb.NewConnection(connectionString)
    if err != nil {
        return nil, err
    }
    return sql.OpenDB(conn), nil
}

func GetEmployees(db *sql.DB) ([]*Employee, error) {
    rows, err := db.Query("SELECT * FROM employees")
    if err != nil {
        return nil, err
    }

    employees := make([]*Employee, 0)
    for rows.Next() {
        var emp Employee
        err := rows.Scan(&emp.ID, &emp.Name, &emp.Salary)
        if err != nil {
            return nil, err
        }
        employees = append(employees, &emp)
    }

    return employees, nil
}

// Employee represents an employee in the database
type Employee struct {
    ID      int
    Name    string
    Salary  float64
}
