Hi
I need to know how this works in detail:
I have sqlite3 database file stored on SD/MMC FLASH card and i would to insert
rows to some tables often. There will be triggers to clean old and obsolete
data.
How often it will write to database file? After every INSERT command, or it
goes to some

Hi,
I would like to build a very light SQL database in javascript. I would
like to learn how sqlite parses an SQL statement and then acts on this
parsed information. Does anyone have a pointer to a link or book that
explains the process at a higher level then source code?
Thank you,
Peter

meen, If SQLite has two index and very large Index (about 10.000.000 each
one) how do i merge it, I mean (index1 = index2 for every one and limit it
in thousand).
Understand?

Excuse me, i'm not good programming in c. A double is 8 bytes width.
How does a function return anything other than 4 bytes (in eax

It depends upon which CPU and calling convention you (and your compiler) are
I've got it: in c doubles are passed to a function by pushing its two
dword parts: first the high and then the low part, and when it's the
result of a double type function is returned in the ST0 of the FPU.
Thank you!

double sqlite3_column_double(sqlite3_stmt*, int iCol);
returns a double, not a pointer to a double.
That seems pretty straight forward to
Hi everybody!
I need a tip about how sqlite3_column_double works. I hoped it returns a
pointer to a 8-byte-real, but it don't.
Here is what i do:
CREATE TABLE [tblTyped] ([a] TEXT, [n] NUMERIC, [i] INTEGER, [b] BLOB)
Insert into tblTyped values('helo,,,', 1.1121, '8.0001', 'blob!!!')
then
18 matches
