SQL Queries vs. Regular Question

FROM rb_projects
WHERE rb_projects.started = 1

This times out I assume because the table is large but if I do the same question in the regular question editor its done in seconds. Why is that?

Is it because it is limited to 2000 rows?

Create using the regular question editor, then convert to SQL. See what differences there are.
If it’s just the row limit, then try increasing to a more suitable value.
