Sql running error

Hi All,
When i am running sql query i am getting error like this , How we can resolve this issues
please help me




Are you running nested queries?

Also, make sure that you’re using the Connect and Disconnect activities before and after your Execute Query activity.

Sounds like you have used the Connection activity and then Execute Query but configured the connection in both. The intent of the Connection activity is to store the connection in a variable and pass it to the other SQL activities. Or just delete the Connection activity and let the Execute Query connect itself.

Thanks its resolved
