Can a database have more than one filegroup?
A filegroup works as a logical container for datafiles. One filegroup can have multiple data files. Now, let’s start with creating a SQL Server database with three data files in one filegroup and a log file.
How to move data between data files in a single filegroup?
Suppose your SQL Server database has multiple data files in a single filegroup with each data file having some data. You have a requirement to consolidate your data files or migrate data from one data file to another. This tip will help you in achieving your goal.
What’s the best way to use multiple filegroups?
Likewise, another, common, strategy for effectively leveraging the performance benefits of multiple files/FILEGROUPs is to put heavily used tables (via JOINs) in a ‘SECONDARY’ FILEGROUP – which has files placed on different physical drives/spindles.
Can a SQL Server have more than one data file?
The secondary data file that is optional and can be used to spread data across multiple disks by putting each file on a different disk drive. Further, a SQL Server database can have multiple data and log files, but only one primary data file.
What should be the default filegroup for a database?
Recommendations when working with files and filegroups: Most databases will work well with a single data file and a single transaction log file. If you use multiple data files, create a second filegroup for the additional file and make that filegroup the default filegroup. In this way, the primary file will contain only system tables and objects.
How to list all objects created on all filegroups?
CREATE TABLE [dbo]. [TestTable]( Next, create non-clustered index on secondary filegroup. CREATE NONCLUSTERED INDEX [IX_TestTable_Second] ON [dbo]. [TestTable] ( After that, we will run the following T-SQL and determine where all the objects are located on filegroup.
