Question

I have table with INTEGER PRIMARY KEY and I cannot insert value greater then 2147483647 as a key. Is it possible to increase this value somehow?

UPDATE:
Ok, I have php script:

<?php

$sqlite_db = new SQLite3('test');
$sqlite_db->exec('CREATE TABLE test (n UNSIGNED INTEGER)');

$ns = array(1111111111,2222222222,3333333333,4444444444,5555555555,6666666666,7777777777);

foreach ($ns as $n)
{
    $statement = $sqlite_db->prepare('INSERT INTO test (n) VALUES (:n)');
    $statement->bindValue(':n', $n, SQLITE3_INTEGER);
    $statement->execute();
}

$sqlite_db->close();
?>

and what I get in test database is that:

root@localhost:~# sqlite3 test 
SQLite version 3.7.3
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> select * from test;
1111111111
-2072745074
-961633963
149477148
1260588259
-1923267926
-812156815

So my question is: how to insert large values into sqlite database from php?

UPDATE2:

I have changed foreach body to:

$sqlite_db->exec("INSERT INTO test (n) VALUES ({$n})");

and it works ok now.

I’ve never seen that behavior with SQLite3. Edit your question, and paste the output of .schema your-table-name. Also, make sure the problem isn’t in your application code.

Declaring a column as integer in SQLite works differently than declaring a column as integer in a true SQL dbms. In SQLite3, any column declared INTEGER PRIMARY KEY ought to accept any 64-bit, signed integer. 64-bit integers max go to 1.84467441 × 10¹⁹. (Your column should accept negative integers, too.)

INTEGER. The value is a signed integer, stored in 1, 2, 3, 4, 6, or 8
bytes depending on the magnitude of the value.

sqlite> create table t ( n integer primary key, s varchar(35));
sqlite> insert into t (s) values ('a');
sqlite> insert into t (s) values ('a');
sqlite> insert into t (s) values ('a');
sqlite> select * from t;
1|a
2|a
3|a

So, it automatically increments . . .

sqlite> insert into t values (2147483647, 'a');
sqlite> select * from t;
1|a
2|a
3|a
2147483647|a

And it accepts the maximum value of a 32-bit signed integer.

sqlite> insert into t (s) values ('a');
sqlite> insert into t (s) values ('a');
sqlite> insert into t (s) values ('a');
sqlite> select * from t;
1|a
2|a
3|a
2147483647|a
2147483648|a
2147483649|a
2147483650|a

And it increments past the maximum value of a 32-bit signed integer.

sqlite> insert into t values (8589934592, 'a');
sqlite> select * from t;
1|a
2|a
3|a
2147483647|a
2147483648|a
2147483649|a
2147483650|a
8589934592|a

It accepts values in the range of 2³³.

sqlite> insert into t (s) values ('a');
sqlite> select * from t;
1|a
2|a
3|a
2147483647|a
2147483648|a
2147483649|a
2147483650|a
8589934592|a
8589934593|a

And it continues to automatically increment.
