When you try to edit the update and delete command provided by the dataset editor suddenly says an error unrecognized @ command

How to repeat:
create a table
Create a dataset from VS2008
Try to edit update/delete comand from the datatable

Hi Rabosa and thanks for your report.

Please inspect, for example, under INSERT command "Parameters" array. Does it say @something or ?something? Also, do you allow user variables in your connection string? Thus far I see no evidence there is a bug here.

Please post at least your connection string...

Using trunk sources and a specific table I am able to repeat this behavior:
mysql> show create table bug40529\G
*************************** 1. row ***************************
       Table: bug40529
Create Table: CREATE TABLE `bug40529` (
  `Col2` int(10) NOT NULL,
  `Col3` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`Col1`)
1 row in set (0.00 sec)

With some other tables it works, can't get better grasp of problem... Toggling user variables on/off makes no difference.

check the pictures edit.jpg(6.0.3) and update_526.jpg(5.2.6) i can see a space between the @ and the name
nom_maquina = @ nom_maquina
nom_maquina = @nom_maquina

Could be there the error¿?
I tryed to change manualy the commandtext on 6.0.3 but the error persists

What's the solution to this? I've tried it in all kinda of scenerios. 6.0.3 just breaks the Dataset Designer completely.
[6 May 2009 13:44] Tonci Grgin
Well, it is rather new product and has it's problems... We'll see what Reggie has to say.
