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.
