How Applications Pass Connection Parameters

Connection parameters are passed to the interface library as a connection string.

This string consists of a set of parameters, separated by semicolons.

In general, the connection string built up by an application and passed to the interface library does not correspond directly to the way a user enters the information. Instead, a user may fill in a dialog box, or the application may read connection information from an initialization file.

Certain Sybase IQ utilities accept a connection string as the -c command-line option and pass the connection string on to the interface library without change. For example, to stop a database named iqdemo on the server myserver, enter:

dbstop -c "uid=DBA;pwd=sql;eng=myserver;dbn=iqdemo"

Note: Interactive SQL processes the connection string internally. It does not simply pass on the connection parameters to the interface library. Do not use Interactive SQL to test connection strings from a command prompt.
