In that case --fk othertable detects the primary key.

If you want to point at a different column, use --fk-col X

Hmm... probably not:

For options, only a fixed number of arguments is supported.

    "total_count": 0,
    "+1": 0,
    "-1": 0,

For the CLI I'm thinking:

sqlite-utils add-column data.db mytable col text --fk othertable id

So the foreign key is added using --fk othertable othercolumn

If the user doesn't provide the column type we can derive it from the foreign key.

Can we make the othercolumn optional? That would be neat - then we could automatically detect it using the sole primary key of the referenced table.

 
{
    "total_count": 0,
    "+1": 0,
    "-1": 0,
    "laugh": 0,
    "hooray": 0,
    "confused": 0,
    "heart": 0,
    "rocket": 0,
    "eyes": 0
