SQLite add Primary Key

Question

I created a table in Sqlite by using the CREATE TABLE AS syntax to create a table based on a SELECT statement. Now this table has no primary key b

Answer 1

I had the same problem and the best solution I found is to first create the table defining primary key and then to use insert into statement.

CREATE TABLE mytable (
field1 INTEGER PRIMARY KEY,
field2 TEXT
);

INSERT INTO mytable 
SELECT field1, field2 
FROM anothertable;
