Hi
I am wondering how I can use the embedded MySQL server in a Delphi application via UNIDAC? Does you have a demo for this? Better give me a step by step guide if possible.
Thanks very much.

Hello,

You can look at the mydacdemo->technologyspecific->embedded demo. This demo demonstrates working with Embedded MySQL Server. If you don't have MYDAC you can download Mydac Trial version. Also you can read the Using Embedded Server topic in Mydac Reference Manual.

Hi, I purchased UNIDAC. Would you include that embedded part of the function in this product? This was a standard feature of MySQL, I presume.

Unidacdemo doesn ' t has the example of working with Embedded MySQL Server. That's why your can look on this example only in Mydacdemo.

You can connect to the Embedded MySQL server with UNIDAC in the following:

Code:select All

  UniConnection.ProviderName := ‘MySQL‘; 
  UniConnection.Database := DatabaseName; 
  UniConnection.SpecificOptions.Values[‘Embedded‘] := ‘True‘; 
  UniConnection.SpecificOptions.Values[‘EmbeddedParams‘] := ‘--basedir=.‘#13#10‘--datadir=data‘;

The--basedir parameter sets the base path for the Embedded MySQL server. All paths is usually used relatively to the base path. The--datadir parameter sets the path to the data directory. Last edited by Andreyz at Wed Oct 11:07, edited 1 time in total.

I'll try it and feed back to you.
Very well thought, unidac!

Using Firemonkey
MySQL 5.5

"MySQL client library couldn ' t be loaded. Libmysqld.dll file to System folder, included to PATH, or to the folder with executable unit of main program. "

Sure placed the Libmysqld.dll (and not libmysql.dll) library to the directory where the executable file of Your application is located. Also, please note this should use 32-bit Libmysqld.dll for 32-bit applications, and 64-bit Libmysqld.dll for 64-bit AP Plications.
