Sql Server Express limitations

Merlin-Eng asked
Last Modified: 2018-10-09
A simple question hopefully......

I'm putting together a specification for a new server, and i'm thinking that I will be able to use SQL Server express. It's limited to 10Gb databases, but our database is currently 1.5 Gb and holds 20 years of our company's data. So that isn't going to be a problem in my lifetime. The only concern i'm aware of is that SQL Server express is limited to 4 cores.

Does that statement mean it will only use 4 of the available cores? or does it mean that it will not run on a machine where the CPU that has more than 4 cores?

Thanks in advance

>> also, the SQL Agent is not available with Express.

I'm glad you pointed that out. I use SQL Agent to backup the database, and to do maintenance. But I can send commands from an external source to do this. Thanks for your help

I too use SQL Express and use solution like https://ola.hallengren.com/frequently-asked-questions.html to backup my database (as well as scheduling other maintenance tasks)
