I need a free sqlite tool for comparing two sqlite database table values. I've used SQLiteSync, but it's not good at it. any more better graphical tool?
I haven't used this, just DuckDucklGo'ed it, but what about
KS DB Merge Tools for SQLite is an easy to use diff & merge tool for SQLite databases. This tool allows to compare and import/export database objects and data between two database files. It can run in two modes - basic free version and paid Pro mode that provides extended functionality and overcomes limitations of the free version.
Free version allows to compare table definitions, diff and merge views, indexes and triggers. It also provides basic data diff and merge facilities, allowing to compare table contents, merge the whole records or only required columns for chosen records.
Pro version has a number of significant functional improvements, such as batch data diff, query result diff and more. In addition it has a lot of small nice refinements that will make your work much more productive.
