Description
The reason is that `select 1` will get node data but schema.
Contributor guide
Research direction
The issue is about SELECT constant queries not printing results in offline and sync modes. Examine the query execution path for constant expressions, focusing on how node data vs. schema is handled. Look at the SQL engine code, possibly around result set formatting or execution modes. Check test files for SELECT constant queries to understand expected behavior.
