Positioning-value

Usage Notes

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 or OK). 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, Data-information-extended, and No‑operation parcels before the Multipart‑record parcel for the start of the data.

Use of this setting does not require use of Change‑option. That is, honoring Positioning‑value depends only upon the setting of Positioning‑action, not Change‑option.
