The SQLITE_VERSION C preprocessor macro in the sqlite3.h header evaluates to a string literal that is the SQLite version in the format "X.Y.Z" where X is the major version number (always 3 for SQLite3) and Y is the minor version number and Z is the release number. The SQLITE_VERSION_NUMBER C preprocessor macro resolves to an integer with the value (X*1000000 + Y*1000 + Z) where X, Y, and Z are the same numbers used in SQLITE_VERSION. The SQLITE_VERSION_NUMBER for any given release of SQLite will also be larger than the release from which it is derived. Either Y will be held constant and Z will be incremented or else Y will be incremented and Z will be reset to zero.

Since version 3.6.18 (2009-09-11), SQLite source code has been stored in the Fossil configuration management system. The SQLITE_SOURCE_ID macro evaluates to a string which identifies a particular check-in of SQLite within its configuration management system. The SQLITE_SOURCE_ID string contains the date and time of the check-in (UTC) and a SHA1 or SHA3-256 hash of the entire source tree.
