Question: ```
1. select count(*) from tableX where code = "XYZ";
2. select count(*) from tableX where code like "%XYZ";

```

Result for query 1 is 18734. <== Not Correct

Result for query 2 is 93003. <== Correct

We know that query 2's count is correct based on independent verification.

We expect these two queries to have the exact same count for each because we know that **no rows in tableX have a code that ends with "XYZ"**, so the wildcard at the beginning shouldn't affect the query.

***Why would these queries produce different counts?***

We have already researched the differences between "=" comparison and "like" string comparison, but based on all our verification checks, we still don't understand why this would give us different counts

We have confirmed the following:

* There are no leading or trailing characters in the "code" field
* There are no hidden characters (tried all found here: [How can I find non-ASCII characters in MySQL?](https://stackoverflow.com/questions/401771/how-can-i-find-non-ascii-characters-in-mysql))
* The collation is "utf8\_unicode\_ci"

We are using MySQL version 5.5.40-0ubuntu0.12.04.1.

Answer: 
It's up to you. If you leave them there nothing bad will happen because the executables have different names (`dnx`/`dotnet`).

You can have dnx and dotnet side by side.
You should not delete this folders if you have old (DNX-based) projects that you still want to run. Otherwise, you will need to reinstall the dnx runtimes again to work with your old (RC1) apps.

Your new (RC2, `dotnet cli`) projects will known nothing about this old dnx-based folder and will ignore it completely.
