where is the name of your server. The following is an example of the table
returned:
Figure 8-1. System Reporter Version Report
This query returns a 3x3 table with the column headers Category, Major, and Minor. The
two rows after the header contain major and minor numbers for Product and ReportData.
The Product version numbers are informational only and are the numbers assigned to the
product when it is released. The Product version number is not necessarily related to the
ReportData version. The Product version of the server will be the same as is displayed in the
upper frame of the Web client.
The ReportData version numbers correspond to the format of the data as provided by the
server. These numbers will change according to the following rules:
■ Bug fixes do not cause a change in version number. If data in a table is being incorrectly
reported, fixing the server to report it correctly does not change the version.
■ Adding one or more new columns to a table without changing any of the existing columns
causes the minor number to be incremented.
■ Removing a column causes the major number to be incremented.
■ Changing the meaning of a column causes the major number to be incremented.
Clients can accept lower version numbers if the client has been coded to work with previous
versions. Clients can accept newer minor numbers when the major number is the same since
the data format is compatible, but may wish to warn the user that not all features of the
server's data will be represented. The client should not attempt to use data from a server with
a newer major number. The simplest approach is for the client to reject a server unless the
major and minor number of the server's data format is the same as the data format
specification used to code the client.
