Bulk-Library version 15.7 supports in-row storage of text, image, and unitext large object (LOB) columns in Adaptive Server.
In Adaptive Server 15.7, LOB columns that are marked for in-row storage are stored in-row when there is enough space available in the row. Only bound LOB data can be written in-row. The bcp utility binds LOB data, thus sending in-row LOB data as applicable. See Chapter 21, "In-Row Off-Row LOB" in the Adaptive Server Enterprise Transact-SQL Users Guide.
