我正在通过X ++中的直接SQL调用存储过程，但我不知道如何从中获取整数返回值。0是好的，-1是坏的。

// Login to SQL DB
loginProperty = new LoginProperty();
loginProperty.setServer('localhost');
loginProperty.setDatabase('SQL_DB');
odbcConnection = new OdbcConnection(loginProperty);
statement = odbcConnection.createStatement();


/*

,@status                        INT

,@dlvmodedesc                    NVARCHAR(50)
,@tracking_id                    NVARCHAR(50)

sqlStatement = strfmt(' EXEC pr_send_status_email ' +
                      ' %1,'        +   // CustomerId
