Can the Express edition be used to do anything ?

Post by myicq » Sat 01 Jun 2019 16:16

I would like to investigate the devart UniDAC product, possibly purchase it. But before, I downloaded the Express edition.

I would like to create a very trivial "hello world" example, where I connect to a WAMP MySQL server, and query a database.

Unfortunately the documentation for the express edition is extremely vague on what you can do. The demos do not compile, no clear mentioning if you need to purchase anything - something about MyDAC is mentioned, but not if it's free or not.

So: can I use the Express edition for anything at all ? For the trivial example, I do not mind using libmysql.dll. If I can use it, a few (trivial) examples would be great. Also for SQLite.

Is there some guides, sample code etc anywhere ?

UniDAC Express Edition includes only basic components and does not include database server providers.
You can connect to MySQL server using UniDAC Express Edition only having installed MyDAC, you should either install MyDAC, which contains the required provider
You can test the required functionality with UniDAC Trial Edition: https://www.devart.com/unidac/download.html, a full-featured time-restricted version of UniDAC Professional Edition.

Thank you for the response. It is unfortunate that beginners cannot start anything with the UniDAC.

Suggestion: why not include a simple / restricted version of at least a few data providers (MySQL / MariaDB / SQLite), which could be limited to "Compiler Running" only, and perhaps also limited in other ways - such as only do SELECT / UPDATE queries, limited number of queries per hour etc.

Just so beginners could run a demo program and see how things work, at the most basic level.

I will trial your full product anyway, and hopefully get allowance to purchase it.

Hope you will consider the suggestion.

You can see a sample using the UniDAC components to work with MySQL server in our UniDacDemo project, which you can find in the directory: %UniDACDemos%\UniDacDemo, where %UniDACDemos% is the path where UniDAC Demo projects are installed on your computer.
