Get a specific column from the database. This is required if you don't know the column reference ahead of time, i.e. when you want to generate a query dynamically from a table. Moya Admin uses this tag, but it unlikely to be useful for general applications.

Example

<db:getcolumn model="${table.params.model}"
     name="id" from="${.url.appname}" dst="id_column" />
