一旦我尝试用数字变量替换表名,代码就会中断。我在 $1 处出现语法错误。

我应该逃避它吗?

如果问题是数字参数,我可以尝试其他方法。

let players = sqlx::query_as!(
              DatabaseGym,
              "select * from ( select * FROM $1 where player=$2 and time <= $3 ORDER BY time desc limit $4  ) temp ORDER BY time asc;",
              matched_table.to_owned(),
              player.to_owned(),
              &x.time,
              count
              ).fetch_all(&self.pg_pool)
              .await.unwrap();
