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 libsqlitefunctions
|
|
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('#{lib}/libsqlitefunctions.dylib');
|
|
sqlite> select cos(radians(45));
