Where are your images stored? In a column of an SQL Table? From Where you
want to copy?
Assumed those pictures are listed within the column LWIIMAGE_F in the
LWIMAGES table, you can write those pictures into the IFS as follows:
1. your need to defined an File Referenece variable for output with the
keyword SQLTYPE(BLOB_FILE).
2. the precompiler will convert the File Reference Variable into a data
structure, containing the IFS file name, the length of the IFS File Name,
the data length and the file opteration.
3. you need to initialize those subfields
4. With a SELECT ... INTO or FETCH the information is written to the IFS
DCL-S MyImage SQLTYPE(BLOB_FILE);
DCL-s YourAUDFID ....;
EXEC SQL Declare C1 Cursor for
Select LWIIMAGE_F , audfid
from lwimages;
EXEC SQL Open C1;
MyImage_Name = '/home/Hauser/MyImageWhatever.jpc';
MyImage_NL = %Len(%Trim(MyImage_Name';
MyImage_FO = SQFOVR; //Constant included by the precompiler = write the
IFS file if not exists, otherwise replace an existing one
EXEC SQL Fetch Next from C1 into :MyImage, :Youraudfid;

Subject: Copy BLOB to IFS
I need to send a BLOB via FTP to another server. It's a JPG.
I'll have to do 5-10 images at a time so I think i'd like to copy the BLOB
to the IFS and then send all of the images in the IFS.
I've been googling, found some examples here but not sure where the image
will go.
I tried this code in SQL and am getting an error that the field LWIIMAGE_F
is not usable.
EXEC SQL Declare C1 Cursor for
Select LWIIMAGE_F ,
audfid
from lwimages;
EXEC SQL Open C1;
EXEC SQL Fetch Next from C1 into :LWIIMAGE_F,
audfid;
