== Purpose ==

TGQuery is the only way used in Gestinux to display data from tables or Sql queries.

You can drop a TGQuery on a form, to be used by a [[TGDbGrid]]. They are linked by a TDataSource in the usual way.

You can also create dynamically a TGQuery.
The Create constructor assign in one time the [[TGDbConnection]], and Sql code, and open the query.
Currently, bind parameters can't be assigned before opening : include the values in the Sql query.

When editing is requested, set the 3rd optional parameter to true : it will try to lock the retrieved record,
If the record is already locked, a message is automatically displayed, allowing the user to wait or cancel.
