Update table statistics dynamically across an entire SQL Server database

8

In Oracle there is a table where all tables in the database (dba_tables) are listed and we can use it to perform maintenance operations dynamically. In Sql Server we can do the same by consulting the table [database].dbo.Sysobjects.

7

ShrinkDatabase SQL ServerIn SQL Server you can use the DBCC SHRINKDATABASE command to reduce the space occupied by the data files and log of a database.

The problem with SHRINKDATABASE is that, contrary to what may seem, if not used carefully, the result can be a significant increase in the fragmentation of the indexes, and tables, which leads to a worsening of performance of our SQL Server, data and even an increased footprint when affected by fragmentation indexes are rebuilt...
