Question

i am using go client "github.com/ClickHouse/clickhouse-go/v2",

this is the go code:

	deadlineCtx, cancel := context.WithDeadline(context.Background(), time.Now().Add(queryTimeout))
	defer cancel()
	rows, err := ch.Query(deadlineCtx, sql)
	if err != nil {
		return 0, err
	}
	defer rows.Close()

ch.Query didn't return err, but there are 0 rows in return.
I am sure query result of sql is not null.

this is the records in system.query_log
