Why does sqlite3_analyzer upcase table names?
(1) By Jeffrey Friedl (jfriedl) on 2020-12-17 06:35:31 [link] [source]
sqlite3_analyzer prints table names in all upper case, as opposed to the actual (possibly-mixed) case that the names are in the database. Does anyone know why?
Would a command-line option to avoid this be reasonable? I know that sqlite3 itself doesn't care about the letter case, but my eyes much prefer to read ThisIsSomeTable instead of THISISSOMETABLE......

SQL in general and SQLite in particular are case blind. Mixing case in names may be prettier to read, but has no significance.

Yes, as I wrote, I understand that SQLite itself doesn't care, but a human reading the output of sqlite3_analyzer almost certainly does. It seems gratuitous for sqlite3_analyzer to upcase the names, but perhaps there's a practical, useful reason?

If names are internally mixed-case but the internals are case-insensitive then it's slower to compare/search them because each character has to be compared 1-2 times during a comparison. If they're internally normalized to either upper or lower case, comparison speed is improved by ruling out 50% of the possibilities in advance.
