Invoking a Java Stored Procedure using SQLJ

Declare and initialize input and in-out variables. For example, if the first parameter is an int input parameter:

int bookID = scanID();
Declare output variables. For example:

int daysLate; String title;
Invoke the stored procedure in a SQLJ statement. In the statement identify the parameters by name, and designate them as :in , :out, or :inout. For example:

#sql { call NPL.CHECKIN (:in bookID, :out daysLate, :out title)} Return values will be assigned to output and input variables.
