The table below contains sample connection strings for all supported SQL data providers. To identify the database type in a custom connection string, use the XpoProvider parameter. Both of these values can be adjusted using an ALTER DATABASE statement.Custom Connection Strings for Data Sources

This would mean that you could not store more an a total of 10MB of data (including system data), and that no individual transaction could be larger than 5MB in size. The MAXSIZE settings in the create database statement will prevent the files from growing beyond those values. Log files do not have the option for IFI (for security and data safety reasons), so any growth on that file will cause IO stalls while that completes, impacting performance.

With IFI enabled (requires Perform Volume Maintenance Tasks permission for the service account, this can be done at install time with SQL 2016) then the data file can grow instantly and does not need zeroing out. Those stalls will last as long as it takes to grow out the file and zero it out to ensure the space is clear (2016 does not use zeroes, however the concept is the same). If you do not have IFI enabled then you will have IO stalls on writes to the data file that cause it to grow. It is generally recommended to not use percentage based filegrowths as this can lead to unexpectedly large file growths, not to mention performance problems.Ī further note to filegrowth. For the data file, that will grow as you insert data, as an when needed. However if in simple recovery then the log will grow as large as is required to support open transactions that happen, or to prevent a loss of data with CDC or replication (if a log continues to grow you can check for reasons using the log_reuse_desc column of sys.databases).

Log files will continue to grow if the database is in full or bulk-logged recovery unless you take log backups.

You can name these however you like (although you cannot have duplicate names within a database). In this example a data and log file are designated and named. The assignment of MyDatabase_Data is for the data file inside the database. Previously the express was a named instance, which requires you to pass along the instance name (or port) in order to connect. The default instance, by name, would be MSSQLServer, however you do not need to provide that.

Back in SQL Server 2012, I would have in code Server=localhost\SQLExpress where Configuration Manager would show the instance as SQL Server (SQLExpress)."SIZE = 2MB, MAXSIZE = 10MB, FILEGROWTH = 10%) " + "FILENAME = 'C:\\MyDatabaseData.mdf', " +
