Sound familiar?
These are the most common SQL frustrations we hear from developers and DBAs
Execution plans are unreadable
SSMS shows you a wall of nodes and arrows. You know something is wrong but have no idea what to fix first.
Queries take forever in prod
Works fine on your laptop, grinds to a halt on production data. Something about indexes, maybe?
No DBA on the team
You are a developer doing DBA work. You do not have time to become a SQL Server expert overnight.
