Querying MySQL and SQL Server from same IDE I am currently working with MySQL and SQL Server. 

For querying MySQL I use MySQL Workbench, for SQL Server I use SQL Server Management Studio. 

I am mixing up shortcuts all the time. For instance, to execute a query in SSMS it's F5 and in MySQL WB it is CTRL-Enter. 

Is it possible to query both databases from the same IDE? A plugin for WB or SMSS? A different IDE that works for both databases?
there is a lot of options but choosing the right one is up to you, this is some of the options :

1) Adminer: http://www.adminer.org/

2) DBeaver: http://dbeaver.jkiss.org/about/

3)DBVisualizer Free: http://www.dbvis.com/

4) sql developer (but you need to install the plugins first) : http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html
