I need to modify a column in a SQLite database but I have to do it programatically due to the database already being in production. From my research I have found that in order to do this I must do the following.

  • Create a new table with new schema
  • Copy data from old table to new table
  • Drop old table
  • Rename new table to old tables name

That seems like a ridiculous amount of work for something that should be relatively easy. Is there not an easier way? All I need to do is change a constraint on a existing column and give it a default value.

    That’s one of the better-known drawbacks of SQLite (no MODIFY COLUMN support on ALTER TABLE), but it’s on the list of SQL features that SQLite does not implement.

    edit: Removed bit that mentioned it may being supported in a future release as the page was updated to indicate that is no longer the case
