Just a quick note. The second link appears to refer to Oracle 8i which
has not been sold by Oracle for more than 4 years.
For example this statement:
"Blob type storage - One long or long raw per table, must be at end of
row, data stored on same block(s) with row."
LONG and LONG RAW data types have been deprecated. The BLOB data type,
as early as 9i held 4GB, had no restriction as to the number per table,
did not need to store the information in the same block with the row,
and did they need to be at any specific location in a table: A statement
which in and of itself is wrong as can be clearly seen:
1 create table ms_is_wrong (
2 col1 NUMBER(5),
3 longcol LONG,
4 col3 NUMBER(5),
5* col4 DATE)
SQL> /
Table created.
SQL> desc ms_is_wrong
Name Null? Type
----------------------------------------- -------- ---------
COL1 NUMBER(5)
LONGCOL LONG
COL3 NUMBER(5)
COL4 DATE
Clearly the LONG does not need to be the last column. And clearly
Microsoft has done its user community no favor with this document
as there are a large number of similarly egregious errors.
