Question

I want create table from another table with constraint?

I used this query “create table destination as select * from source;” fro table creation.

But its copy only the column name in table without column constraint.

Answer 1

There is a special table named sqlite_master, holding the full CREATE TABLE statement for each table (it’s modified as appropriate during ALTER TABLE).

I would make my application retrieve that CREATE TABLE statement:

SELECT sql FROM sqlite_master WHERE type='table' AND name='source';

Then I would replace the table name right after CREATE TABLE tokens, and execute the result as a new sqlite query.

I don’t think that it’s possible to do in sqlite’s pure SQL without extensions.
