Hi everyone,

 I am trying to insert a row in sqlite table with my own unique id. I want
to create unique id using sqlite internal function
last_insert_rowid()  which returns the next max rowid of the table which is
always unique. I tested this using sqlite and it works fine but when i run
the same query using RSQlite from r prompt, my query doesn't create new
unique id. 
last_insert_rowid()  always returns 0 value from RSQLite always returns 0.
How can I get a unique id using RSQLite ? 

my query looks like this
 "insert into PrimaryIdTable values ('AMP AT

reason i am not using INTEGER PRIMARY KEY  is because i want to keep my key
as TEXT datatype. This is because another table has same field for secondary
id and both these keys appear in same table so i want to call them primary
key (P1, P2 ) or secondary key (S1, S2 etc) . 

Thanks for your help,
