Is there a way to capture SQL error when run datastore.update() return -1? For some reason SQLCA.SQLCode and SQLErrorText are empty  when ds failed to Insert or Update a row.

Thanks,

Yuri

Hi Yuri,

I always use a ds_base custom datastore class instead of the system class. For your case I would add the following instance variables and event code:

INSTANCE VARIABLES
PUBLIC:
boolean​  DisplayDBError     // Governs DBError return value
​DWBuffer DBError_Buffer
long     DBError_Row
long     DBError_SQLDBCode
string   DBError_SQLErrText
string   DBError_SQLSyntax
​
​EVENT DBError
this.DBError_Buffer = Buffer
this.DBError_Row = Row
this.DBError_SQLDBCode = SQLDBCode
this.DBError_SQLErrText = SQLErrText
this.DBError_SQLSyntax = SQLSyntax

​if this.DisplayDBError then return 0 else return 1

ANYWHERE ELSE IN CODE
ds_base lds_data
lds_data = create ds_base
​lds_data.DataObject = "d_myData"
lds_data.Set​TransObject(SQLCA)
...
IF lds_data.Update( ) < 0 THEN
   // Error details =>
   // ​lds_data.DBError_SQLDBCode, lds_data.DBError_SQLErrText, ...
END IF

I missed >>> In your scenario, I expect to see SQLDBCode = -3 (Row changed between retrieve and update).



DW engine expects SQLNRows = 1 for each UPDATE/DELETE but DBMS returned SQLNRows = 0.

Hi,

 

You can Insert -> Object -> "datastore (or userobject - n_ds)" into your Window/userobject

 

You have now access to the dberror event ( and sqlpreview ) on the inserted object

 

Regards

Georgios
