[database] Difference between CLOB and BLOB from DB2 and Oracle Perspective?

They can be considered as equivalent. The limits in size are the same:

  • Maximum length of CLOB (in bytes or OCTETS)) 2 147 483 647
  • Maximum length of BLOB (in bytes) 2 147 483 647

There is also the DBCLOBs, for double byte characters.
