ANTS Memory Profiler 7.1 without license

Hi All,

The trial period of 14 days of your ANTS Memory Profiler has passed.

You are now searching for a license for ANTS Memory Profiler?
Or are you searching for a crack for ANTS Memory Profiler?
Or are you searching for a keygen for ANTS Memory Profiler?

No need to do that anymore because there is an easy way to use it without having a license, crack or keygen (Note: the version that I am using is 7.1).

So what to do?

SQL Performance Tips 4

Hi All,

Again me with some more SQL Performance Tips.

If you have a lot of tables with which you have to join and those tables are big then pay attention to the order of how you join those tables because the order matters.

Why the order of the tables in joins matters?

It is because even if the result of your query returns only a few of records, lets say 7 records, it doesn't mean that it will run fast, and it will not run fast because during the first joins your tables can "return" thousands, millions or even more records with which the SQL Server will be working further.

So the idea is that you have to use the Actual Execution Plan to see what is Estimated Number of Rows with which the SQL Server will be working with.

Try to filter the data using the joins, so that less data remains to be processed, and less time it takes to the SQL Server to return the result to you.

Good luck,

SQL Performance Tips 3

Hi All,

Me again with another SQL Performance tip.

Another way to optimize a query is using the Actual Execution Plan.

Well, first of all by using it you will see what indexes are missing, what table or join is causing the performance issue, which join is returning a lot of rows and many more.

It worth learning how to use the Actual Execution Plan.

Now about indexes, you must keep in mind that not all indexes that are suggested to be created by Actual Execution Plan are good to be created, and this is for several reasons:

SQL Performance Tips 2

Hi All,

Here are some more tips on SQL Performance.

So what is it useful for?
First of all what is it doing: Stops the message indicating the number of rows affected by a Transact-SQL statement from being returned as part of the results.

Which means that when you do not need the number of rows affected to be returned from the SPROC then write that at the beginning of the SPROC. Why? because it will reduce the traffic and the execution time of your SPROC.

SQL Performance Tips 1

Hi All,

By working at some performance issues with SQL Stored Procedures, Views and Functions I had to make some investigations on SQL performace, how to do that, I've been searching a lot to find some tips.

So the first tip is: Avoid using CURSORS.

Yes, avoid cursors, do everything to avoid cursors.

Often time people say to me that for their case it is not possible to avoid cursors, and often times I prove them that it is possible.

When there is just a few things that you could do with a set of data then try to do that in some statements by joining the data, instead of going through each item.

It is not always clear that cursors could be avoided, this is why you have to think several times if it is really not possible to avoid them.
