Missing Indexes

Situation

SQL Server registers every missing index. Here is how you retrieve that information from the missing index DMV's

The WHERE clause contains a filter that only shows the missing indexes for the current databases and only for indexes that are missing for more then 10 times. You can change that how ever you want.

Result

The result is a list of CREATE statements that you can copy and execute in your database. The names of the indexes are somehow prefabricated, you can adjust that formula.  

We especially pay attention to the data in the yellow marked area. For example If the amount of rows is very high and the user seeks is very low and the last user seek was a week ago, we wouldn't create that index of course. But if the rowcount was for example 200000 and the user seeks above 1000 and last user seek actual with current date then yes.
