To configure Microsoft SQL Server Express, perform the following tasks on the machine with SQL Server installed.
Once this configuration is complete, you can use the database with PaperCut NG/MF by following the instructions in Upsize to an external database (RDBMS). It is assumed that SQL Server Express is already installed with the default configuration.

This section described how to configure Microsoft SQL Server Express edition for use with PaperCut NG/MF. These limitations includeĤGB limit on database sizes (10GB for SQL Server Express 2008/2012/2016) But these limitations are not likely to adversely affect most PaperCut NG/MF users.

However, it does have some limitations when compared to the full version of SQL Server. Server Express provides enterprise class database performance for free. Microsoft SQL Structured Query Language (SQL) is a special-purpose programming language designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS). However: the 10GB limit for SQL Server Express takes priority, so even if you have maxsize = Unlimited (or maxsize = 20GB or whatever) you would find the actual database size would not grow beyond 10GB.Available in PaperCut NG and PaperCut MF. It's useful to set 'maxsize' to an actual number, then if you have multiple databases on one disk you can set the sizes to prevent one database from using up all the disk space. In the second result set the first line shows the allocated size of the data pages in the 'size' column which is your most accurate estimate.Įdit: The 'maxsize' column shows the maxmum size the file is allowed to grow to, or can be 'unlimited' to allow the file to grow to use the entire disk. The mdf file size is not always accurate as it contains unallocated data pages and (generally) does not shrink when data pages are no longer required.Ī quick way to accurately find the used space is to run the SQL command: exec sp_helpdb 'myDatabase' The 'space available parameter from DB properties' you asked about is the unallocated space in the data file (mdf) and the transaction log file (ldf). If you discover that the logfile is indeed oversized and you don't need the option for point in time recovery, you can change the recovery model to simple and that will reduce it's growth significantly You can check the log file size: DBCC SQLPERF (LOGSPACE) But it is possible that most of your database size is the log file, especially if you have done lots of updates and deletes and you haven't done any backup. If for some reason you belive your databse had grown into unrealistic size, you can use DBCC SHRINKDATABASE()Īs for the express limit, I'm not sure exactly how it is calculated. The available space is how much empty disk space you can use before the next growth. Since it is inefficient to re allocate for each record, it grows by x% or xMB (you can define these). MySQL supports the LIMIT clause to select a limited number of records, while Oracle uses FETCH FIRST n ROWS ONLY and ROWNUM. Note: Not all database systems support the SELECT TOP clause.
Returning a large number of records can impact performance. You may start with a 1GB but it will grow to 3GB over time. The SELECT TOP clause is useful on large tables with thousands of records. SQL Server will allocate more disk space as your database grows. Since the file is set to 10GB exactly, I suspect that it has been grown out to this amount deliberately to take advantage of the full amount of space offered by SQL Express. + CASE is_percent_growth WHEN 1 THEN ' ' ELSE '' ENDĪs an aside: Since your data file is at 10GB already, future growth operations will fail (and whatever transaction triggered the growth will generate a Primary Filegroup Full error). + CASE max_size WHEN 0 THEN 'DISABLED' WHEN -1 THEN ' Unrestricted'ĮLSE ' Restricted to ' + CAST(max_size/(128*1024) AS VARCHAR(10)) + ' GB' END WHEN 1 THEN CAST(growth AS VARCHAR(10)) + '% -' ELSE '' END , = 'By ' + CASE is_percent_growth WHEN 0 THEN CAST(growth/128 AS VARCHAR(10)) + ' MB -' The following script will show some more detailed information about data file sizes/growth settings: SELECT If you'd like to see this in more detail, I'd recommend querying the system tables rather than relying on the SSMS GUI (which isn't always going to give you the information you want/need).

Somewhat confusingly though, the Free Space value shown on this window only relates to the data file(s). The Size shown on the database properties window is the data and log file combined sizes.
SQL Server Express only imposes file size limits on data files, log files can grow to any size. In SQL Server Express user connection limit is 32,767.
