Sqlite Drop Column
Q: How can I drop a column in sqlite-databases?
A: It is not possible to drop columns within sqlite using the syntax ALTER TABLE DROP COLUMN . However, there is a workaround for this issue :
BEGIN TRANSACTION; CREATE TEMPORARY TABLE t1_backup(a,b); INSERT INTO t1_backup SELECT a,b FROM t1; DROP TABLE t1; CREATE TABLE t1(a,b); INSERT INTO t1 SELECT a,b FROM t1_backup; DROP TABLE t1_backup; COMMIT;
It's obvious that this is a little bit complex. But if you use sqlitebrowser  this can be done with a few mouse-clicks (look under -->modify table for a button "remove field".
