Commad preview returned non-success : Error[HY090][Microsoft][ODBC Driver Manager] Invalid String or buffer length

Hi,

I am trying to connect MS Access Database using ODBC(via Direct Access Gateway).

I am getting the following error while preview the data in the connection Tab.

Error.png

 

But i was able to load the data from load script window.

Is there any setting need to be done to succeed in the preview window?

 

Thanks,

John.

O erro apresentado na imagem:
 
ERROR [HY090] [Microsoft][ODBC Driver Manager] Invalid string or buffer length
 
indica que o Driver ODBC está tentando ler ou pré-visualizar os dados e encontrou um problema relacionado ao comprimento de uma string ou buffer, geralmente causado por:
 
 
🔎 Causas comuns
1.Campos com comprimento indefinido (Memo, LongText, etc.):
•Campos como Memo ou LongText no Access podem causar erros durante a visualização na interface gráfica (preview), especialmente quando usados via ODBC.
2.Problemas de compatibilidade com o Direct Access Gateway:
•Nem todos os drivers ou tipos de dados funcionam corretamente em modo de pré-visualização no Qlik via Gateway.
3.Driver ODBC Access desatualizado ou incompatível:
•Versões antigas ou não compatíveis do driver podem causar falhas durante o preview, mesmo que a carga funcione.
