Views can be synchronized with Data Compare for SQL Server only if:
1. Compare the views with Data Compare. When configuring the comparison options in the New Data Comparison Wizard, make sure that the Compare views option is selected.
2. Notice which rows are different.
3. Use the Data Compare for SQL Server tool to compare and synchronize the tables with the differing rows.
You cannot directly synchronize queries with Data Compare. But you can get an update script and apply it against a target database instead.
