What is BLOB/LOB/DBCLOB?
- A large object is a data type used by DB2 to manage unstructured data. DB2 provides three built-in data types for storing large objects
Creating BLOB Table space:
Ref:Craig mullins article.
Example:
CREATE LOB TABLESPACE TDORGCHT
IN DSN8D10A
LOG NO
USING STOGROUP DB2NNN
PRIQTY 144000
SECQTY 144000
LOCKSIZE LOB
LOCKMAX 0
BUFFERPOOL BP47
DSSIZE 64 G
GBPCACHE SYSTEM;
COMMIT;
CREATE AUXILIARY TABLE DEPT_ORGCHART_TAB
IN DSN8D10A. TDORGCHT
STORES DSN81010.DEPT
COLUMN DEPT_ORG_CHART;COMMIT;
LOB(Large object data) will be stored in different format. We will have LOB locator in Auxilary table.
BLOB is a datatype of the column. In Both Oracle and DB2 the datatypes are the same. Check fo details.
