Advantage database with Firedac

adyble

Hi
We have moved from RB7 using D7 and Advantage Database server via the daAds.pas plugin from RB 20, Delphi 10.3 and FireDac to connect to ADS. When opening our existing reports we get an error TdaADSQueryDataview not found. I am guessing there is something we need to change in each rtm file. Could someone give me a pointer what to look for and change please?
Thanks
Andy

More info - When we open the data tab on the report it's blank. In File Data settings
Sessions type = FirteDAC session, Database Type = Advantage, If I choose New query designer or query wizard it displays a list of empty adt filenames, for example space followed by ADT and no fields listed.

Hi Andy,

In order to convert your templates to use a different database connection, you will need to manually edit the source of each template (hopefully programmatically) to match the new dataview classes, tables, etc. See the following article on some strategies about how this should be done.

I was able to recreate the issue you had with the table names not appearing when connecting to an Advantage DB with FireDAC. There is now a patch available that solves this problem for RB 21.01.

Hi Nico
We tried this today but the data part of the file is in a format I don't recognise -
How can we extract the database setitngs as text ?
Thanks
Andy

Hi Andy,

The section of the template you have copied above is RAP code in a proprietary format we used for older versions of ReportBuilder. This format will be updated when you save the template again with a newer version of ReportBuilder. There is nothing here, however, that should be altered to function correctly with a new DB connection as it does not apply to the DADE QueryDataViews.

As stated in the article I posted, you will want to look for the DataModule section of the template and alter the QueryDataView class as needed (as a minimum). Then you will need to go through that section of the template and change table names, field names, property values, etc. if needed. The best way to do this is to create a simple report from scratch and compare it to the older template to see what needs to be done.

The section of the template you need to look for will look something like the following:

object daDataModule1: TdaDataModule
object FireDACQueryDataView1: TdaFireDACQueryDataView
UserName = 'Query_Orders'
Height = 298
Left = 10
NameColumnWidth = 105
SizeColumnWidth = 35
SortMode = 0
Top = 10
TypeColumnWidth = 52
Width = 242
AutoSearchTabOrder = 0
object plOrders: TppChildDBPipeline
