I will build in some general sql functions to next version of [[tkSQLiteGUI]].~
Here is the list of the functions. You can blild in these functions to your database freely.
NOTE: This is under developed, so these may be changed.
*** How to build in the functions to your db [#eaf68944]
package require sqlite3
source sqlitefunc.tcl
sqlite db :memory:
foreach cmd [info command Sqlite::func::*] {
db function [namespace tail $cmd] $cmd
}
then
% db eval {SELECT MD5('md5 test')}
