Hi Anuli

Thank you for letting me noticed that I posted a question in Chinese.

Sorry, I have no idea why my web translate English to Chinese by itself, here is my question.

When I query the data when my query statement allows query data but if the data is concatenated. If it does not exist, it will be displayed as blank, if it exists, to modify the data. Does it need to be selected in the tool? This clause allows querying data but not when concatenating data. If it does not exist, it will be displayed as blank, if it exists, to modify the data. Does it need to be selected in the tool?

Hello Yijing,

Could you please share your OML or some screenshots of your database model, actions and screens to understand the issue?

Thanks & Regards,

Sachin
