This issue we notice if a connection string has not set in expected format
like: connection string in test step or datasheet has given as below
jdbc:sqlserver://[SERVER_NAME]:{PORT}
where as the SQL SERVER has multiple databases and the given query table exists on a database say DB1. Since the Devtest can not find on which database, this table exists. Due to that, we get an error.
To fix this error, please add databaseName parameter to connection string like below
jdbc:sqlserver://[SERVER_NAME]:{PORT};databaseName=DB1
and execute the query.
