为了Scan将值直接转换成[]string，您必须创建一个[]interface{}指向字符串切片中每个字符串的切片。
在这里，您有一个适用的MysqL示例（只需更改sql.Open-command以匹配您的设置）：
package main
import (
"fmt"
_ "github.com/go-sql-driver/MysqL"
"database/sql"
)
func main() {
db, err := sql.Open("MysqL", "user:pass@tcp(localhost:3306)/test?charset=utf8")
defer db.Close()
if err != nil {
fmt.Println("Failed to connect", err)
return
}
rows, err := db.Query(`SELECT 'one' col1, 'two' col2, 3 col3, NULL col4`)
if err != nil {
fmt.Println("Failed to run query", err)
return
}
cols, err := rows.Columns()
if err != nil {
fmt.Println("Failed to get columns", err)
return
}
// Result is your slice string.
rawResult := make([][]byte, len(cols))
result := make([]string, len(cols))
dest := make([]interface{}, len(cols)) // A temporary interface{} slice
for i, _ := range rawResult {
dest[i] = &rawResult[i] // Put pointers to each string in the interface slice
}
for rows.Next() {
err = rows.Scan(dest...)
if err != nil {
fmt.Println("Failed to scan row", err)
return
}
for i, raw := range rawResult {
if raw == nil {
result[i] = "\\N"
} else {
result[i] = string(raw)
}
}
fmt.Printf("%#v\n", result)
}
}
