MS SQL Server Error 926 & 945

Implementation of memory allocation and their storage requirements which are responsible for management is totally different to the disk space. You may notice it when you migrate or change the location of SQL database tables. The space occupied by each tables exceeds its storage limit which may be less or greater than 8 KB. As you know that each tables data stored in a page whose maximum storage limit is 8 KB. Hence page is a basic unit of SQL Server database, it has been a point of concern that many SQL users tried to use, because as they have observed free space.
