How much can SQLite store on the iPhone?

Question

I have an idea for a webapp for the iPhone but its unknown to me how much data can be stored in mobile Safari\'s SQLite db. I tried searching through the Apple docs but foun

Answer 1

It's most likely 32 terabytes... which is well over the available disk space.

I reached this number by multiplying the maximum page size by the maximum page count listed at the bottom of the SQLite limits page.

Answer 2

The default storage limit on iPhone seems to be 5mb

Answer 3

Caution: my iphone is jailbroken! But I don't suspect that this changes anything.

The limit of 50MB is no longer correct.

On my iPhone 4S with iOS 6.1 I have a database of 58.66 MB (448496 records) for my webclip (website pinned to the springboard).

No special tricks, just standard HTML5 usage.

Answer 4

It's as the other posters say. You're only limited by the drive space on the device.

You also need to consider your in memory footprint though. There is a finite amount of memory on the iphone, and in general it's quiet small, so the amount of data/hydrated objects you'll be able to have in memory is another potential limitation for your app.

Answer 5

Maximum Database Size

Please refer Official Sqlite site

Every database consists of one or more "pages". Within a single database, every page is the same size, but different database can have page sizes that are powers of two between 512 and 65536, inclusive. The maximum size of a database file is 2147483646 pages. At the maximum page size of 65536 bytes, this translates into a maximum database size of approximately 1.4e+14 bytes (140 terabytes, or 128 tebibytes, or 140,000 gigabytes or 128,000 gibibytes).

This particular upper bound is untested since the developers do not have access to hardware capable of reaching this limit. However, tests do verify that SQLite behaves correctly and sanely when a database reaches the maximum file size of the underlying filesystem (which is usually much less than the maximum theoretical database size) and when a database is unable to grow due to disk space exhaustion.

davibe has done some work to raise the limit up to 1GB with his PhoneGap plugin. https://github.com/davibe/Phonegap-SQLitePlugin

The plugin calls the native sqlite3 API, with a wrapper on the Javascript side.
The relevant code extracted from sqlite.js are:

update origins set quota = '999999999999' where origin = 'file__0';   
"update databases set estimatedSize = '999999999999' where name = '" + dbName + "';'";
