Looks like it goes inside this loop in 3.7.12 at line 1883 of shell.c. Could
we get maybe a pragma ".mode csvblob" or such and have this made a permanet
part of the shell?

Joshua,
It doesn't exist in the standard version. We added it in-house to aid
development and testing. The code I posted was the changes we made to
the 3.5.9 shell.c in addition to adding an existing hex to byte function
from our libraries.
If you can compile a new shell the existing shell
Hey Jim,
I downloaded the source or 3.7.12 from sqlite.org and can't find that code.

$ head -n3 sqlite3.c
/**

$ cat sample.tsv

CREATE TABLE samples (
method varchar(64),
value blob

insert INTO samples (method, value) VALUES ("insert - null", null);

I updated my csvimport utility to allow hex fields.
So hex fields like X'01020304' will get imported as blobs if the option is
enabled.
Sooo
test.csv:
X'0001063500',X'00'
X'0001063501',X'01'
csvimport test.csv test.db t
csvimport -x test.csv test.db t
We added blob import on an old version of the shell, 3.5.9. Using a
simple HexToByte function.
To function: static int do_meta_command(char *zLine, struct
callback_data *p){
Added:unsigned char * blobBuffer = NULL;
In the loop // * Bind cached values to prepared statement. *
I peeked at the source code real quick and it looks like it just
converts the contents of the file into a bunch of SQL that is
essentially opening a transaction and doing an insert for each row
followed by a commit. This suggest I just need to format it
differently so I'll play around with that tom

That document you quote is describing the SQL langa
I set the separator to tab and then in the file it is
X'somevalue'\tX'someothervalue'\n
X'morestuff'\tX'evenmore'\n
but with real hex values
According to the documentation
BLOB literals are string literals containing hexadecimal data and
preceded by a single "x" or "X" character. For example:

.import is for .csv files. What are you putting in the .csv file to express a
value i
I've tried searching for awhile and haven't had any luck. I'm able to
store and retrieve blob data using inserts and the hex encoded
literals like this
INSERT INTO rolled (roll1, roll2) VALUES
(X'0001063500',X'00');
But when I try to use the .import method the values get impor
