I have a habit of putting schema definitions in a file that's always safe to read and execute against a DB connection. This means that I DROP some things IF EXISTS and CREATE all things IF NOT EXISTS. But if I have to ALTER TABLE... there's no IF NOT EXISTS .. equivalent for ALTER TABLE. Funny

[sqlite] alter table add column

"Alter table add column" command drop data from table. Can you keep the data or should I store the data before the alter and then put them in the table? -- Fabio Spadaro www.fabiospadaro.com ___ sqlite-users mailing list sqlite-users@sqlite.org
