The "sqlite3" command:
Usage: fossil sql ?OPTIONS?
Run the standalone sqlite3 command-line shell on DATABASE with SHELL_OPTS.
If DATABASE is omitted, then the repository that serves the working
directory is opened. See https://www.sqlite.org/cli.html for additional
information.
Options:
--no-repository Skip opening the repository database.
-R REPOSITORY Use REPOSITORY as the repository database
WARNING: Careless use of this command can corrupt a Fossil repository
in ways that are unrecoverable. Be sure you know what you are doing before
running any SQL commands that modify the repository database.
The following extensions to the usual SQLite commands are provided:
checkin_mtime(X,Y) Return the mtime for the file Y (a BLOB.RID)
found in check-in X (another BLOB.RID value).
compress(X) Compress text X.
content(X) Return the content of artifact X. X can be an
artifact hash or hash prefix or a tag. Artifacts
are stored compressed and deltaed. This function
does all necessary decompression and undeltaing.
decompress(X) Decompress text X. Undoes the work of
compress(X).
delta_apply(X,D) Apply delta D to source blob X and return
the result.
delta_create(X,Y) Create and return a delta that will convert
X into Y.
delta_output_size(D) Return the number of bytes of output to expect
when applying delta D
delta_parse(D) A table-valued function that deconstructs
delta D and returns rows for each element of
that delta.
files_of_checkin(X) A table-valued function that returns info on
all files contained in check-in X. Example:
SELECT * FROM files_of_checkin('trunk');
now() Return the number of seconds since 1970.
REGEXP The REGEXP operator works, unlike in
standard SQLite.
symbolic_name_to_rid(X) Return the BLOB.RID corresponding to symbolic
name X.
