buy server space

I often think that in support of spatial information, because it lacks the storage of geometry, MSSQL is always a bit slower than other databases. With the support of the new. NET CLR, you can really add your own based on. NET objects. Although I tried to implement a simple geometric type of storage in SQL Server, there were some limitations that I had to give up. First, the user data type cannot exceed 8000 bytes. That is, a geometry object cannot ex

In SQL Server, tempdb is primarily responsible for the following three types of situations: Internal use (sort, hash join, work table, etc.)External use (Temporary tables, table variables, etc.)Row version control (optimistic concurrency control)For internal use, some of the more complex queries because of a large number of parallel, sorting and other operations require a large amount of memory space, each
