查询只是使用varargs来替换sql中的参数，因此，在您的示例中，您只需要执行
rows, err := stmt.Query(10)
例如，这个和第二个示例的内容是动态的，那么您将
stmt, err := db.Prepare("SELECt * FROM awesome_table WHERe id=$1 AND other_field IN ($2, $3)")rows, err := stmt.Query(10,"this","that")如果“ IN”部分具有可变的args，则可以执行（播放）
package mainimport "fmt"import "strings"func main() { stuff := []interface{}{"this", "that", "otherthing"} sql := "select * from foo where id=? and name in (?" + strings.Repeat(",?", len(stuff)-1) + ")" fmt.Println("SQL:", sql) args := []interface{}{10} args = append(args, stuff...) fakeExec(args...) // This also works, but I think it's harder for folks to read //fakeExec(append([]interface{}{10},stuff...)...)}func fakeExec(args ...interface{}) { fmt.Println("Got:", args)}
