Calling Ingres Tools from Embedded SQL and OpenSQL
How Ingres Tools Are Called from Embedded SQL and OpenSQL
The call statement in embedded SQL and OpenSQL lets your applications call an Ingres tool (such as QBF) or the operating system.
When an Ingres tool is called from an embedded SQL or OpenSQL program, you can specify parameters, many of which have the same effect as flags used when the tool is called from the operating system command line.
Some of the tool parameters correspond to arguments passed to the particular tool, others to specific command line flags.
For each call, the flags parameter can be used to pass the values of all flags, including those that do not have defined parameter names. Within the string containing the value for flags, each distinct flag must be separated by a blank space.
