Positioning‑value specifies either the row number, the byte offset into a BLOB, or the character offset into a CLOB, from which the Fetch is to be performed when Positioning‑action indicates other than Next‑parcel.
When specifying a row number, by convention, a value of zero represents parcels that precede the first row (such as Success, OK, or StatementStatus). When specifying a byte or character offset, by convention, a value of zero corresponds to the first byte or character. A value of zero also returns Success or StatementStatus, Data‑information‑extended, and No‑operation parcels before the Multipart‑record parcel for the start of the data.
