Hi,
Is there any possibility to import files from the local file system to the
sqlite DB.And Is there any export option is there just to check whether the
loaded file and exported file consists of same data or not.
Is it possible in sqlite?
If possible,How it will stores files in tables?In which f

Sqlite requires few resources. Locking is achieved through regular file
locks which lock the entire database since it is a file.
Flow control is not applicable.
You may use semaphores etc in your application for synchronization, but
they are not used by Sqlite.

Hi Everybody,
I have the following doubt...
1. what are the resources required by SQLLite - they can be RAM/ROM,
semaphores, mail boxes, task requirements;
2. How do we have flow control?
3. what are the Lock mechanisms provided by the engine (row lock, table
lock..)? Any additional lock mech

Sandhya,
You use Sqlite the same way you use a file in your application. You
link in the runtime library containing the file handling API when you
create your executable. Sqlite gives an embedded application the
capability of using SQL for data management.

Sandhya,
You have not grasped the concept of Sqlite. It is a RDBMS LIBRARY, not
a server. You link Sqlite into your application. As Dr Hipp points out
it it an alternative to fopen, not Oracle.

Hi,
If a table has a primary key selecting count(*)
using it maybe faster if there is a difference
of the number of rows stored per page. A wide table
will do more io than the index. The table names is
not very wide but does consume more disk space than
than the primary keys index.
