I dont know its a little bit late. But if all your servers are mysql, why dont use the 'servers' feature of mysql and the 'FEDERATED' table engine . With that you can register external mysql servers that can be accessed by a main one creating a table of type 'Federated' which its data will always co...

Hi To all just wanted to give my two cents about this: You should take a look to the project: http://code.google.com/p/sv-utils/ also http://code.google.com/p/sv-utils/wiki/Intro Specially the SQLite 3 components There Tim Anderson have already translated the headers necessary to register custom fun...

Hi I'km having alittle problem migarting an existing project from delphi 2007 (zeos 6.6) to delphi XE (zeos 7). the database used is mysql 5.1, and now zeos expects a WideString intead of a string field,an all my TzQueries and tzqueries have TString fields, Zeos 7 requires this field to be TWideStri...

You can download 5.1 GA version directly from mysql. latest 5.1 has included the embedded version and I think it includes the innodb support.

rememeber it have to be libmysqld.dll (the las 'd') and not libmysql.dll, you can find it in any mysql 5.1 distribution in the 'embedded' folder. Also the Embedded demos was made for 4.x version.

One important thing where we can add the PingServer a similar TestConnection function that can resume a connection if it is lost. Currently, for example, if ...

Hi Mark, about PingServer Solution i think setting 'result := 1' can be the best solution for databases that doesn't implement yet PinServer functionality. But something we have to be sure is what result does MySQL Ping functions returns if Pinging server is successfully, don't remember if it is 1 o...

Just want to add my two cents for this topic: Zeos will assign default values for fields only after sending the updates to the server (by calling 'Post' or 'ApplyUpdates') and if the field's value is null and if the 'opCalcDefaults' in TZquery.options is set to true. obviously it works with the tabl...
