Is there anyway to use a non-static lifetime of &str to fetch a stream?

[busmaker]

I am implementing a kind of dynamic table feature, users can create any tables and columns as they want, so the backend needs to generate the sql dynamically.

When I try the following the code

      let sql_st = format!(
            "select * from {} where {}",
            table,
            &join_cond_parts(cond_parts)
        );
      let row_stream = sqlx::query(&sql_st).fetch(&self.db);

, the compiler complains this cast requires that 'sql_st' is borrowed for 'static'.

The only solution I can come up is to put the sql_st into a staitc container like map, vec, etc, but it's not thread-efficiency since it requires a lock to achieve querying.

Anyway that I can get the stream query result without a non-static lifetime &str?

Thank you!
