The SQLite database engine will not crash or segfault or otherwise cause
your program to stop running if it encounters garbage data in a file.  But
it will return SQLITE_CORRUPT, indicating that your database is corrupt.

That wording does not mean a specific value, but is intended to mean
something like "if you modify the database file from outside the sqlite3
API, results are undefined" where "undefined" means "almost certainly
corruption."

For example:

echo "123" >> mydbfile

that could effectively corrupt it even though it doesn't actually modify
any bytes used by the db. (Whether or not that _does_ corrupt it depends
largely on how sqlite3 tracks the logical end-of-file.)

[sqlite] sqlite crash info

2012-01-02 Thread Lalitkumar Choudhary
Hi,

I want to know one thing about sqlite crashing, you had mentioned in your 
document which i had found in your website(www.sqlite.org).
Sqlite database will crash if you write some garbage value into the file. May i 
know exactly what is the garbage value? Is it any value different from datatype 
or anything else, can u please give one example?

Thanks & Regards
