I'm a complete newbie. Need to insert a Company logo into a database
column to use later on in a check printing application. Read how to
insert the pointer instead of the object into the column. Below is
what I did:

SET QUOTED_IDENTIFIER OFF
GO
INSERT INTO BankInfo
(CoLogo) VALUES(0xFFFFFFFF)

***Then I did this****

DECLARE @Pointer_Value varbinary(16)
Select @Pointer_Value = TEXTPTR(CoLogo)
FROM BankInfo
WHERE CMCo = '91'
WRITETEXT BankInfo.CoLogo @Pointer_Value
"\\192.31.82.77\Data\CheckImages\WyattLogo.jpg"

****This was straight out of a book and it seemed to work it gave me a
message that it was successful and when I view the data in the column
I can see the pointer
0x453A5C436865636B496D616765735C57796174744C6F676F2E6A7067*****

But when I try to use the column in either Crytal Report or an Access
Report the Bank Logo does not show up. I also placed the logo on my C
drive and tried pointing to it there with "C:\WyattLogo.jpg" with no
success.

It can't be this difficult to get a Company logo into a column. I
desperately need assistance. Remember I am the ultimate newbie. I
looked at my first sql database last week. Thanks in advance for any

Alas, it is not that easy. What you have there, is some sort of
binary representation of the URL itselt. (Actually, it is not. This
is from your attempt to use C:\WyattLogo.jpg.) SQL Server is not going out
to access the web or your disk to read the JPEG for you. You need to say:

WRITETEXT BankInfo.CoLogo @Pointer_Value
0xFFD8FFE1D8454578...

Where the hex string is contents of the file itself. The "pointer" in
this context is a pointer with SQL Server, to the special area where the
value for this image column are stored.

So how would you do this in practice? Most commonly, I think people
use the ADO method AddChunk write a program that reads the binary
file and sends down in pieces. But you could of course also write a
program that constructs the entire SQL batch with hexstring and all.
(If you use AddChunk I don't think you need to convert to hexstring.)
