Using the @ Symbol
The @ symbol is a literal character. If you specify a database server name, blank spaces are not valid between the @ symbol and the database server name. Either put a blank space between dbname and the @ symbol, or omit the blank space.
The following examples show valid database specifications, qualified
by the database server name:
empinfo@personnel
empinfo @personnelIn these examples, empinfo is the name of the database and personnel is the name of the database server.
