In Clarion, I have a third party template that I can add to my application - it's job is to detect if an application update has changed the structure of one of the application's database files... if a change is detected (e.g. a field is added; an index is added; a field changed from a string to an integer; a field length has been lengthend; etc), a new empty table is created at runtime; the contents of the old table are migrated to the new table; the old table is renamed (to serve as a backup) and the new table is renamed to the old table's name, and a runtime error is stopped due to a data type mismatch. The template controls it all - within a few mouse clicks I can add that functionality and it takes no coding at all to benefit from this feature. Needless to say, this template is worth its weight in gold - it has saved me from having to write a dedicated "data transfer" application that has to be ran on every customer's machine.. I know the WD IDE can / will do this - the $1,000,000 question is this: is a WD application capable of also detecting a change in the table schema when it opens the table and then doing the steps above, or will the WD application halt itself with a critical error and the application terminates?30WEBDEVen_UShttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/36933-clarification-sought-ability-change-data-structure-fly/read.awpmoderateur@pcsoft.fr (El moderador)webmaster@pcsoft.fr (El webmaster)vvidopcsoft.us.windevhttps://forum.pcsoft.fr/es-ES/pcsoft.us.windev/36933-clarification-sought-ability-change-data-structure-fly-49983/read.awp21 Jan 2015 13:39:06 ZI have exactly the same question (I guess this is a typical newbie question when switching from Clarion and FileManager).
