Predetermined size fields (fixed-length fields)ĭelimited fields (that is, TERMINATED BY or ENCLOSED BY) In LOBFILEs the data can be in any of the following types of fields, any of which can be used to load XML columns:Ī single LOB field into which the entire contents of a file can be read SQL*Loader reads LOBFILEs in 64 KB chunks.
