  1. Update all products at once rather than just SQLDC

    Have the "check for updates" check for updates to all installed RedGate products? This would be helpful for those of us on frequent updates - having to close SSMS to update Sql Source Control and then again to update Sql Prompt a few minutes later generally is a bit slow...

    • Create the new functionality to support SQL comparing with ACCESS, EXCEL, or even CSV

      As there are usually more than just SQL being used by a company, most likely they are also using Spreadsheet (the current EXCEL are much more powerful than ever), csv and even Access, it is very common to come up the need to import/export data between different formats, while SQL does not really provide a smooth user experience in the past and now. It would be great if red-gate can deliver that functionality in the future.

      • Have an option to continue a previously failed compare

        Sometime (when comparing over a VPN connection) the comparing stops due to a transport-level error. When this happens, I'd love an option to "continue" a previous compare. (Starting with the last table the software was working on at the time of the failure.)

        • large number of partitions

          SQL Data Compare is extremely slow for databases that have a large number of partitions (e.g. > 10,000 partitions). Even just loading the list of tables to compare takes about 10 to 20 minutes in this case. Similarly, the comparison operation takes 10 to 20 minutes... even if the partitioned tables aren't included in the comparison! Given that the partitions aren't relevant to populating the list of tables and the slowness during the comparison occurs even if the partitioned tables aren't being compared, it seems like it should be possible to speed this up. Usually partitioned tables have too many…

          • Memory Issue with Version 12.0.35.3485.

            It crashes after running out of memory with 1m rows to copy on 12Gb RAM during data insertion / update. The database comparison phase is fine.
            Version 11 use to work without any memory leaks.

            • Compile for 64bit

              I keep running into problems with running out of memory when trying to Synchronize databases.

              It appears the application is 32bit still as it seems to run out of memory around 4GB. Recompile the app for 64bit please so I can use all my 32GB of RAM...

                  On Windows 7, the edges of the SQL Data Compare window don't seem to allow window resizing, and there's no visible border separating the window from the background.

                  • Reduce temp space usage

                    I am currently using SQL Data Compare. When I ran it against one of our databases, with all tables it consumed all the space on C:. I am doing selections of tables at a time and it's still consuming more space on each run. If I restart it clears down the temp folder. any chance of clearing down at the start of each comparison?

                    • in V12 don't automatically re-synch when switching deployment direction

                      This is actually a deal breaker for me, because I often am switching back and forth to get different tables in sync, and this adds a lot of time to the process. Please at least add an option for this, it really interferes with my work flow.

                      • Add a project setting that NOT automatically data compares new tables

                        When in the xml project file a new table is not available and the table exists in the database sql datacompare now automatically compares this table.

                        For a lot of user tables this is not the expected behaviour.
                        It would be nicer, if the user can configure if 'unknown' tables will be automatically compared or not.

                        So please add a setting that new tables are not included in the compare automatically.

                          • On Windows 10 with 125% dpi setting, the splitter indicator draws at the wrong location

                            When dragging the pane splitter with the mouse, the dark gray split bar draws about 25% up and to the left of where it should be.

                            • Compare mode: Synchronize / Insert only new data

                              It would be nice to have a feature that compares tables and inserts only new rows (but does not compare / update / delete existing rows).

                              Benefit: The compare process would be MUCH faster if it had only to check if the number of rows differs or to make an OUTER JOIN on the PK fields instead to compare (the CHECKSUM() of) all fields

                              There needs to be several levels of compare:
                              - only empty tables -> skips if the target table is not empty; fastest, could be used e.g. for syncing new created tables

                              - only when row number…

                              • In DC 12 minimize the mapping pane by default

                                Unlike old versions of data compare the screen that shows all the tables i can check and set a where clause on also shows the table mapping by default every time. I almost never look at the mapping screen because i'm comparing two identical databases all the time. Please minimize or hide this by default again.

                                  Great products, couldn't live without them!

                                  We maintain a lot of projects. I'd love to see some way that the projects can be organized into folders or a tree structure. At the moment the flat structure gets messy. Understand how you can save your projects in different folders in your file system..

                                  Thanks

                                  • Disable unique constraint indexes

                                    If a table has a unique constraint index on say the name column and the change is just sapping the names on the IDs. The script to update the names ends up failing because it causes a unique constraint violation, but if the index is disable, then the update runs, then the index is rebuilt the unique constraint does not cause a failure.

                                    • Provide support for custom comparison queries

                                      While browsing the improvements, I notice a whole set of ideas centered around the ability to filter data, providing support for data types that may have changed between stages in the database lifecycle (development to QA to production for instance), and the ability to filter columns, changing column names, etc.

                                      All of this could be supported by providing custom SQL query support in SQL Data Compare.

                                      The tool should provide for a custom comparison query for the source and destination table.

                                      • Provide explicit table and schema exclusion

                                        This improvement is similar to https://redgate.uservoice.com/forums/147879-sql-data-compare/suggestions/4157645-exclude-special-schema-from-datacompare, but I would like to sketch the idea out a little further.

                                        SQL Data Compare should provide a filtering option that allows the user to exclude entire schemas from comparison, or to exclude tables explicitly. This can be done somewhat at the schema level by unmapping an Owner.

                                        But this doesn't provide the feedback on the main screen that I would like to see. There should be an additional Type on the main screen named "Deselected for comparison". Tables or schemas that are not mapped shouldn't be put into the "could not be…

                                        • Allow a filter on comparison key types.

                                          Usually We are only syncing data for lookup tables only. It would be nice to be able to filter out specific datatypes for Keys e.g. int, bigint usually not necessary.
