Sample text

Com/products/text Why Not Use LONGs? In Oracle7, most applications storing large amounts of unstructured data used the LONG or LONG RAW data type. Oracle8i and Oracle9i’s support for LOB data types is preferred over support for LONG and LONG RAWs in Oracle7 in the following ways: ■ ■ ■ LOB Capacity: With Oracle8 and Oracle8i, LOBs can store up to 4GB of data. This doubles the 2GB of data that LONG and LONG RAW data types could store. Number of LOB columns per table: An Oracle8, Oracle8i, or Oracle9i table can have multiple LOB columns.

BLOB, CLOB, and NCLOB data is stored out-of-line inside the database. BFILE data is stored in operating system files outside the database. Oracle9i provides programmatic interfaces and PL/SQL support for access to and operation on LOBs. LONG-to-LOB Migration API Oracle9i supports LONG as well as LOB datatypes. When possible, change your existing applications to use LOBs instead of LONGs because of the added benefits that LOBs provide. See Chapter 7, "Modeling and Design", "LOBs Compared to LONG and LONG RAW Types" on page 7-2.

XML Documents Can be Stored in XMLType Columns as CLOBs Composed XML documents can be stored in CLOBs. XMLType columns use CLOBs for storage. See Also: Oracle9i Application Developer’s Guide - XML, Chapter 5,for information about XMLType, and how XML is stored in LOBs.
