How to retrieve SUM value with SQL Query in Embedded Block?

Could someone help me understand how I can retrieve this sum value using an SQL query in an embedded block?

I've tried this, but it's not working:
SELECT SUM("Price") AS total_price FROM blocks WHERE id='20240226045157-aamgpcf'

But this is working...
SELECT * FROM blocks WHERE id='20240226045157-aamgpcf'
