为什么附录的最后一句话没有显示在网络上？

Question

实际上，我追加后的数据库（mysql表）的最后一句话没有显示在我用Echo框架创建的Web中。

我在第39行有问题：评论项未扫描并显示在本地主机上：1324。

package main

    import (
        "database/sql"
        "fmt"
        "net/http"

        _ "github.com/go-sql-driver/mysql"
        "github.com/labstack/echo"
    )

    type datatype struct {
        SiteID          string `sql: "Site_ID"`
        Scope           string `sql: "Scope"`
        Region          string `sql: "Region"`
        Province        string `sql: "Province"`
        Vendor          string `sql: "Vendor"`
        Supervisor      string `sql: "Supervisor"`
        SOAC_Date       string `sql: "SOAC_Date"`

        COC_Date        string `sql: "COC_Date"`
        FAT_Date        string `sql: "FAT_Date"`
        FAC_Date        string `sql: "FAC_Date"`
        Comment         string `sql: "Comment"`
    }

    func pegy(c echo.Context) error {
        db, err := sql.Open("mysql", "root:Abc@12345@tcp(127.0.0.1:3306)/test")
        if err != nil {
            return c.JSON(http.StatusBadRequest, "Error while connecting to DB!")
        }
        defer db.Close()
        row, _ := db.Query("select Site_ID,Scope,region,province,vendor,supervisor,SOAC_Date,Last_Visit_Date,number_of_visit,COC_Date,FAT_Date,FAC_Date,Comment from test.db")
        var res []string
        for row.Next() {

            res = append(res, fmt.Sprintf("Site_Id: %s |Scope: %s|Region: %s |Province: %s|Vendor: %s |Supervisor: %s |SOAC_Date: %s|Last_Visit_date: %s|Number_of_Visit :%s|COC_Date: %s|FAT_Date: %s|FAC_Date: %s|Comment: %s", db.SiteID, db.Scope, db.Region, db.Province, db.Vendor, db.Supervisor, db.SOAC_Date, db.Last_Visit_Date, db.Number_of_Visit, db.COC_Date, db.FAT_Date, db.FAC_Date, db.Comment))
        }
        return c.JSON(http.StatusOK, res)
    }

    func main() {
        e := echo.New() //By Shayan
        e.GET("/", pegy)
        e.Logger.Fatal(e.Start(":1324"))
    }
