Usage instructions for applications calling the sqlite3 API functions:
|
|
|
|
In your application, call sqlite3_enable_load_extension(db,1) to
|
|
allow loading external libraries. Then load the library
|
|
%%LIBFILE%% using sqlite3_load_extension; the third argument
|
|
should be 0. See http://www.sqlite.org/cvstrac/wiki?p=LoadableExtensions.
|
|
Select statements may now use these functions, as in:
|
|
|
|
SELECT cos(radians(inclination)) FROM satsum WHERE satnum = 25544;
|
|
|
|
|
|
Usage instructions for the sqlite3 program:
|
|
|
|
If the program is built so that loading extensions is permitted,
|
|
the following will work:
|
|
|
|
sqlite> SELECT load_extension('%%LIBFILE%%');
|
|
sqlite> select cos(radians(45));
|
|
0.707106781186548
|
|
|
|
Note: Loading extensions is by default prohibited as a
|
|
security measure; see "Security Considerations" in
|
|
http://www.sqlite.org/cvstrac/wiki?p=LoadableExtensions.
|
|
|
|
If the sqlite3 program and library are built this
|
|
way, you cannot use these functions from the program, you
|
|
must write your own program using the sqlite3 API, and call
|
|
sqlite3_enable_load_extension as described above, or else
|
|
rebuilt the sqlite3 program to allow loadable extensions.
