Thank you great firstly! According to your advise, I used Get column information. But unfortunately, error 4101 always occured when using a index array vi following it to get certain columnname. I want to know the index of column and row for the first columnname in database is both zero? I think it really needs more patience to find out the error. Then, I try another method to get results.Use the Request column informatin vi in Get column information connected to get column name. Because I thought that the principle in Get column information was similar. However, it was still wrong.And I want to ask how can I see the query results from Get column information in detail.
Thanks again.
