SQL SERVER – Database Size Limitation in SQL Express

express SQL SERVER   Database Size Limitation in SQL ExpressI have a tendency to write a number of interview style questions and those are quite popular in this blog. Having said that, sometimes we get asked about tricky questions on a small variety which we might know some of the basics – but sometimes it makes us think twice. This blog is an inspiration on someone who quizzed me with a number of questions on SQL Server Express Edition and I thought to put them up here in a FAQ style for reference.

We all know that there is a limit in SQL Server Express Edition with respect to the size of the database. There have been many confusions around this area. This blog post is meant to come clear of those doubts – by no means this is not exhaustive of all. I have kept them in Q&A format and would add more.

  1. What is the size limit you are talking about in SQL Server Express Edition?

That is a function of  the version of SQL Server:
SQL 2000 Desktop Engine (MSDE) has limit of 2 GB data file(s) size.

SQL 2005 Express Edition has limit of 4 GB data file(s) size.

SQL 2008, SQL 2008 R2, SQL 2012 and SQL 2014 Express Edition has limit of 10 GB data file(s) size.

  1. What is the error I would get if I cross that the limits of data sizes mentioned above?

You are likely to face errors in that scenario. Here are two common errors for reference:
CREATE DATABASE or ALTER DATABASE failed because the resulting cumulative database size would exceed your licensed limit of 10240 MB per database

Size in the error message would depend on limit of that SQL Version of Express. The above message is from SQL 2008 R2 till SQL 2014.

In ERRORLOG, you would see errors as below when limit is reached.
Could not allocate space for object ‘TableName’.’IndexName’ in database ‘DatabaseName’ because the ‘PRIMARY’ filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup.

  1. Is this limit on size for per instance or per database?

The size limit is per database so if the database is composed of multiple data files, then the limit is across all data files in the single database.

  1. Can I have 2 databases of 10 GB each in SQL Server 2014?

Yes. As explained in #3 its per database data file limit.

  1. Does this limit include Transaction Log (LDF) file?

No. It’s only for data files.

  1. Does this limit include File stream file container?

No. It’s only for data files.

  1. Is there any workaround to increase the limit?

There is none to increase the file size limitation. Filestream is not part of the limit so is possible move the blob data file stream.

  1. Will my database be unusable?

No. Adding new data, which needs file size increase would fail with the error mentioned above. SELECT can still run on the database.

  1. What if I want to upgrade to full version of SQL from SQL Express?

That can be done using “Edition Upgrade” Below talks about EVAL edition but same steps can be applied for SQL Express upgrade also.

SQL SERVER – Evaluation Period Has Expired – How to Activate SQL Server?

  1. What else can be done?

Delete unwanted data and shrink the data file.

These are some of the common questions I have seen around with SQL Server Express Edition and its file size limits. Do let me know if you wanted to know anything specific in this area with Express Editions. Will be more than happy to expand the FAQ list to include them. Drop in a line via comments.

SQL SERVER – Dedicated Access Control for SQL Server Express Edition – An error occurred while obtaining the dedicated administrator connection (DAC) port.

Recently I had faced very interesting situation. Due to some reason we were not able to login into the production server for one of client. The reason for the same was that server was very busy, we had to login into the system and bring server to normal situation. When all the attempts failed, I decided to login using Dedicated Administrator Connection (DAC). However when I attempted to connect using DAC it threw following error for me.

expressstart0 SQL SERVER   Dedicated Access Control for SQL Server Express Edition   An error occurred while obtaining the dedicated administrator connection (DAC) port.

C:\Users\pinald>sqlcmd -A -d master -S .\SQLEXPRESS

Sqlcmd: Error: Microsoft SQL Server Native Client 11.0 : SQL Server Network Interfaces: An error occurred while obtaining the dedicated administrator connection (DAC) port. Make sure that SQL Browser is running, or check the error log for t he port number [xFFFFFFFF]. .Sqlcmd: Error: Microsoft SQL Server Native Client 11.0 : Login timeout expired.Sqlcmd: Error: Microsoft SQL Server Native Client 11.0 : A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.

I was bit taken a back as I knew that my commands are correct to login and if DAC does not work, there should be some serious reason for it. When inquired further about the SQL Server version I learned that it was SQL Server Express version deployed. To conserve resources, SQL Server Express does not listen on the DAC port. There is an additional step to be done if SQL Server Express has to be used with DAC. Enable TRACEFLAG on SQL Server Express will enable the connection by DAC possible. Here is the quick methods how one can enable DAC on SQL Server Express.

Go to Start >> All Program >>Microsoft SQL Server (your version) >> Configuration Tools >> SQL Server Configuration Manager.

expressstart00 SQL SERVER   Dedicated Access Control for SQL Server Express Edition   An error occurred while obtaining the dedicated administrator connection (DAC) port.

Click on SQL Server Services >> Select your SQL Server Express version >> Right Click Properties >> select Startup Parameters

expressstart1 SQL SERVER   Dedicated Access Control for SQL Server Express Edition   An error occurred while obtaining the dedicated administrator connection (DAC) port.

Once on the Startup Parameter add the Startup parameter which is TRACEFLAG -T7806. Click on OK and RESTART SQL Server Express edition. Now once again try to connect to SQL Server Express edition and it will work just fine.

expressstart3 SQL SERVER   Dedicated Access Control for SQL Server Express Edition   An error occurred while obtaining the dedicated administrator connection (DAC) port.

This is absolutely documented method on BOL and SQL Server Express needs to be restarted.
