Christophe, I agree with Dr. DeSoi that it may not always be possible to automate schema transformations. However, if you need to compare the metadata between two databases, the free, open-source SchemaCrawler for SQL Server tool will do this for you. You can take human-readable snapshots of the schema and data, for later comparison. Comparisons are done using a standard diff tool such as WinMerge. SchemaCrawler outputs details of your schema (tables, views, procedures, and more) in a diff-able plain-text format (text, CSV, or XHTML). SchemaCrawler can also output data (including CLOBs and BLOBs) in the same plain- text formats. SchemaCrawler is available at SourceForge: http://schemacrawler.sourceforge.net/ Sualeh Fatehi
