SQLCONNECT specifies connection parameters that are used by several of the database administration utilities, such as Interactive SQL, dbinfo, and dbstop, when connecting to a database server.
The SQLCONNECT environment variable is optional, and is not set by the installation program.
This string is a list of parameter settings, of the form parameter=value, delimited by semicolons.
The number sign “#” is an alternative to the equals sign; use it if you are setting the connection parameters string in the SQLCONNECT environment variable. Using “=” inside an environment variable setting is a syntax error. The = sign is allowed only in Windows.
