Pavel Rodionov 14 Years Ago The explained aproach lacks one thing - schema incremental update. If you add/drop some column, you need to drop whole table, or create DML migration scripts for expando tables (which is entertaining task for one entity, but if you have a lot of entities it could take whole day, if not more) Please sign in to reply.

A simple ExpandoColumnLocalServiceUtil.deleteColumn(ong companyId, long classNameId, String tableName, String columnName);will remove the column from the table as well as all values associated with it!

So for every added/removed column some precondition should exist? What if I add 50 columns in a row. Also I don't understand how it will work if I want to change type of column, for example from ExpandoColumnConstants.STRING to ExpandoColumnConstants.DATE. Please sign in to reply. Reply as... Cancel Juan Fernández Pavel Rodionov 14 Years Ago Hi Pavel:1.- The idea is to avoid doing this by hand in every installation of the product. If you have a plugin you can deploy it in the server and it'll do all that tasks.2.- The number of columns is not important: just add it in the hook code.3.- You can use the type you need for your field using ExpandoColumnConstants and it shouldn't be a problemRegardsJuan Please sign in to reply.

Francisco Aranda 13 Years Ago I've tried to run this code in LR6, but it seems that addTable and getTable are deprecated. If I'm not wrong, what is the right way to add expandos in LR6? Thanks. Podrías darme una manito u orientarme con esto. Gracias! Please sign in to reply. Reply as... Cancel Francisco Aranda Francisco Aranda 13 Years Ago Sorry, I didn't look so well. The method is deprecated but it still exists. the new method has a new added companyId parameter. So I'm going to see what happen if I pass the companyId param. Please sign in to reply. Reply as... Cancel Juan Fernández Francisco Aranda 13 Years Ago Hi Francisco:thanks for the update. I didn't realize this has changed. If you add the companyId to the method it'll be ok.
