Tool for querying databases
I want to query a number of different databases mainly Oracle and Informix. Can anyone suggest me some tool using which I can do this easily?
Try WinSQL lite at http://www.indus-soft.com/SynametricsWebApp/WinSQL.jsp. It is absolutely free and does not expire. It is only one file and does not come with any bulky DLLs. If you don't like it, simply delete the file from your hard drive.
An introduction about how to use it against an informix database can be found in this article.
