I am using dB Browser for SQLite

CodePudding user response：

You may update via a substring operation:

UPDATE yourTable
SET ts = '2025-' || SUBSTR(ts, 6, 14);

Note that SQLite does not actually have a timestamp/datetime type. Instead, these values would be stored as text, and hence we can do a substring operation on them.
