SQL.Execute("update TABLE set DATA = ? where ID = ?", SqlRaw(data), q);
You cannot use SqlExp for this. That is why I usually split the process into two parts: I use SqlExp to do the insert, then update to set longraw value.

in oracle8 you use SqlRaw?
I see only in Oracle7 it is processed!

Yes, I am using Oracle7  (It works all the way up).
"7" is minimal requirement. They have changed C api in Oracle 8 and it does not support LONGRAW anymore (if I remember well), replacing it with BLOBs.

Mirek,
I tried Oracle7 but without success:
It remain on execution command: oci7.oexec(&cda); from bool OCI7Connection::Execute() on second(last) call.
Can you help me with this? Maybe i did something wrong!
I uploaded image from file direct from file like this:
String v_img_data(LoadFile(p_image_location));
curr_st.SetParam(1, SqlRaw(v_img_data));
is it correct?
according by this documentation The method OCIDefineByPos support long raw type (SQLT_LBI).
Thank you in advance

OK!
The problem is resolved! the problem was: I lock the table in TORA.
Thank you Mirek for help!
I propose to include SqlRaw in Oracle8 class!
The patch is here:
