In the JDBC API, java.sql.Blob is the mapping for the SQL BLOB (binary large object) type; java.sql.Clob is the mapping for the SQL CLOB (character large object) type. BLOB and CLOB objects are collectively referred to as LOBs (large objects). The Derby implementation of the java.sql...

This support enables operations on LOB-based data types across pluggable databases (PDBs) in an Oracle Multitenant environment. 在这个版本中,支持基于数据库链接的LOB-based数据类型的操作,比如CLOB、BLOB和XMLType。 这种支持支持在Oracle多租户环境中跨可插入数据库(PDBs)上的基于LOB-based数据类型的操作。
See Section 13.7, “Data Type Storage Requirements”. BLOB values are treated as binary strings (byte strings). They have the binary character set and collation, and comparison and sorting are based on the numeric values of the bytes in column values. TEXT values are treated as nonbinary ...
