I upload keywords to DB Yes, I do, but I'm getting error

Are you how to load these keywords? This is not one of the clearly accepted methods (SQL loader, external table from delimited file). Details will be affected here, because it appears that there is a bug in your code or your architecture. The more information you provide, the more likely it is that you will get an enjoyable outcome.

Edit

There is still not enough information. Obviously there is some dispute between running your Excel ODBC and some other process ODBC. If you say that ...

The keywords have been properly uploaded

... then my advice is to forget about it . However, if you really want us to help solve this problem ...

but I am getting this error at this time

< P> ... you will explain your architecture and process in more detail.

The option is yours
