>&#13;     If you have BLOB (BYTE or TEXT) columns in the query, you can add
     a <TT

><I
>blobidarray</I
></TT
> parameter containing the
     corresponding "blob ids", and you should replace those columns
     with a "?" in the query text.
    </P
><P
>&#13;     If the contents of the TEXT (or BYTE) column allow it, you can
     also use "ifx_textasvarchar(1)" and "ifx_byteasvarchar(1)".  This
     allows you to treat TEXT (or BYTE) columns just as if they were
     ordinary (but long) VARCHAR columns for select queries, and you
     don't need to bother with blob id's.
    </P
><P
>&#13;     With ifx_textasvarchar(0) or ifx_byteasvarchar(0) (the default
     situation), select queries will return BLOB columns as blob id's
     (integer value).  You can get the value of the blob as a string
     or file with the blob functions (see below).
