Blob error if the subtype isn't binary

[felipedllinfo]

Hi,
I have an issue, there is a blob colum that isn't subtype binary and when i made a select and try to save the file it isn't recording correctly. i try to cast in select but without success.

Updating the case,
I try to do this cast:
SELECT CAST(CAST(X.CBD_VLR_BLB AS BLOB SUB_TYPE 1 SEGMENT SIZE 80 CHARACTER SET NONE) AS BINARIO)
FROM CBD_CONFIGURACOESBD X
WHERE X.CBD_DSC = key

but it doesn't work, i create a new field with this set and it works. But i need to use this field, because the system works with it.
