Batch Data Diff

Batch Data Diff allows to compare data for multiple tables and views. This tool can be opened using 'Batch data diff (Ctrl+Shift+B)' toolbar button:

With click on any calculated count you can drill-down to data diff to check these records. For views new and changed records count can not be calculated since they do not have primary keys and therefore it is not possible to detect whether the record was added or changed.

Query Result Diff

With 'Query result diff (Ctrl+Shift+Q)' you can compare arbitrary query results:

This can be convenient if you want to specify some column or row filter. You can split this window to specify two queries and compare their result, in this case you can also run both queries against the same database.

Note that query results can not be merged.

Custom Data Diff

With 'Custom data diff (Ctrl+Shift+C)' you can compare any tables and views with ability to specify custom field mapping. At least one field mapping item must be defined with mapping type 'Key':

This dialog also can be opened from the regular data diff window by 'Field mapping' link and from query result diff in 'customize field mapping' mode.

Export to Excel

Export to Excel generates Excel reports for object list, data diff, batch data diff, query result diff and table structure diff. Click the 'Export to Excel (Ctrl+Shift+E)' toolbar button to export data grid from the currently opened tab:

For the data grids that allow record/object selection (such as table diff view), only selected records will be exported, if any records were selected.

Open password-protected files

You can open password-protected files using 'Open file(s) with password (Ctrl+Shift+O)' toolbar button or 'with password' link on the project tab:

You can save file open security options to an sqlts file, which can be used later using regular Open File action or as a command line argument. It can be very convenient if you often work with the same protected files. You put your credentials only once, save sqlts and use it without entering credentials anymore. Note that everything, including passwords, is saved as a plaint text and this file must not be shared with other persons. 'Use relative paths' option allows to save project file name in sqlts file relative to sqlts file location. For example, if you save your sqlts file to the same folder with project, then you can move both project file and sqlts file to some other folder without breaking sqlts file. Next time you will open sqlts, it will search for project file in the same folder again.

Extended diff facilities

As you could notice on the Overview page - object list, data diff and text diff views provide the following additional diff functionality:

'Next change (Alt+Down)' and 'Previous change (Alt+Up)' toolbar buttons to search for the next/previous block of changes in the data diff and text diff views.

total, new, changed and new+changed record/line counts,

display selected row in the separate vertical side-by-side comparison panel at the bottom of the window. For text diff it also provides by-character comparison,

paging in data diff allows you to work with large amounts of data,

sorting in data diff will help you to arrange and find required records.

No data diff and merge limitations

Free version provides basic data diff and merge facilities with the following limitations:

both tables must have compatible single-column or two-column primary keys,

no more than 50 columns

Views data diff

You can compare view results the same way as for tables using 'Compare data' and buttons. Click on these buttons will bring up a 'Define query key fields' dialog with the list of common fields. Select number of fields that can uniquely identify query row to detect new and changed records. When you click OK, Pro version checks that chosen fields match this criteria, otherwise you will get a warning and will have to select other fields.

Command line arguments

You can open projects in Pro version using command line arguments. For this you need to same your database connectiviry settings to *.mydbs files, this should be done from 'Open databases..' dialog. The format of command line arguments is

sqlitemerge.exe left_file_path right_file_path

Other enhancements

Customization - you can setup lot of options in Settings window - what and how to compare by default.

Find tab - drill-down links to occurrence with focus on target row in the text diff view.

In object list and Batch Data Diff you can use 'Filter (Alt+F)' command to filter object names by substring. This can be very convenient for large lists.

Copy to clipboard support for text diff, object lists and table diff views.
