go語言將表數據動態轉成切片(字段任意拓展)

package main import ( "log" "fmt" "database/sql" _ "github.com/go-sql-driver/mysql" ) //先把字段的值都當成字符串 func Rows2SliceMap(rows *sql.Rows) (list []map[string]string) { //字段名稱 columns, _ := rows.Columns() //多少個字段 length := len(columns) //每一行字段的值 values := make([]sql.RawBytes, length) //保存的是values的內存地址 pointer := make([]interface{}, length) // for i := 0; i < length; i++ { pointer[i] = &values[i] } // for rows.Next() { //把參數展開，把每一行的值存到指定的內存地址去，循環覆蓋，values也就跟着被賦值了 rows.Scan(pointer...) //每一行 row := make(map[string]string) for i := 0; i < length; i++ { row[columns[i]] = string(values[i]) } list = append(list, row) } // return } func main() { db, err := sql.Open("mysql", "root:1234@tcp(192.168.99.165:3306)/test?charset=utf8") if err != nil { log.Println(err.Error()) } err = db.Ping() if err != nil { log.Println(err.Error()) } rows, _ := db.Query("select * from cms") defer rows.Close() list := Rows2SliceMap(rows) for k, v := range list { fmt.Println(k) fmt.Println(v["id"], v["name"], v["sex"], v["age"]) } }
