-- | DATABASE : Oracle |
-- | FILE : example_create_clob_8.sql |
-- | CLASS : Examples |
-- | PURPOSE : Example SQL script that demonstrates how to create tables |
-- | containing a CLOB datatype in Oracle8. One of biggest |
-- | differences between creating a CLOB in Oracle8 and Oracle8i or |
-- | higher is the use of the INDEX clause within the LOB clause |
-- | declaration. In Oracle8 it is possible to name the LOB INDEX |
-- | and declare a tablespace and storage clause for it. With |
-- | versions Oracle8i and higher, it is still possible to name the |
-- | INDEX LOB SEGMENT using the INDEX clause but these versions of |
-- | Oracle (8i and higher) will simply ignore anything else within |
-- | the INDEX clause (like tablespaces and storage clause.) From |
-- | what I have read Oracle is deprecating the tablespace and |
-- | storage clauses from being used within the INDEX clause. |
-- | NOTE : As with any code, ensure to test this script in a development |
-- | environment before attempting to run it in production. |
