Two BLOBs in a single table
So, I have a table:BLOB_TABLE
Number of BLOB_ID automatically triggered (sequence primary key)
BULLETIN BLOB
BULL_FILE VARCHAR (255)
BULL_MIME VARCHAR (255)
DATE OF BULL_LAST_UPDATE
SUPERFORM BLOB
SUPER_FILE VARCHAR (255)
SUPER_MIME VARCHAR (255)
DATE OF SUPER_LAST_UPDATE
When I try to view a BLOB, it will show only the last BLOB responsible for this record.
Can I store two types of BLOB data in a table? It doesn't seem to matter how I even try to show (even using the 'Download' link attached to traverse file).
Or I have to create two tables and link them together (I'd rather not do that if I have to).
Please notify.
Hello
Maybe I just misunderstood your question, but on
Apex. Oracle.com
workspace: put
user: guest
Pass: apex1234
request blobtest - pass to page 2!
I just download 2 different blobs at once...
---
Take a look at the defs of the ID column (which I have 2 times) - here in the format you add WHICH column to download: DOWNLOAD: BLOBTEST:BULLETIN:ID (for the first id)

Hello Muzz,
Perhaps the example of human Chen reveals a design error.
If a student has a 'teacher_id' "teacher" FK and FK for "emp" becaue each teacher is an EMP, I guess that the correct design would be to have only the FK of 'teacher' and to have another pointing to the 'emp' table in the 'teacher' tabe FKBut we can imagine comical situations...
CREATE TABLE PEOPLE (id NUMBER of KEY PRIMARY, name VARCHAR2 (20 CHAR),...);
CREATE TABLE SCIENTIST (id people KEY PRIMARY NUMBER (id) REFERENCES, discipline VARCHAR2 (20 CHAR),...);
CREATE TABLE POLICEMAN (id REFERENCES to KEY PRIMARY NUMBER (id), hire_date people DATE,...);First table = all.
2nd: a subset of the first, with people having the profile of 'scientific '...
3rd: a subset of the first, with people being a policeman.
It might be people first table and in none of the 2nd and 3rd, 1st and 2nd, 1st and 3rd only or in the 3 tables.Then we can have a fourth table of 'something' referring to a person who must be a scientist and a police officer.

Jack,
- Tables should not be used for web page layouts.
- Tables for tabular data such as spreadsheets and graphics only.
- Today, we use an external CSS file for the layout, typography and other styles.

- I created a hash cluster single table like this:
create tablespace mssm datafile 'c:\app\mssm01.dbf' size 100 m
Segment space management manual;
create the cluster hash_cluster_4k
(id number (2))
size 8192 single hash table is id hashkeys 4 tablespace mssm;
--Also created a table cluster with the line size such as single record corresponds to a block and inserted 5 records each with a separate key value
CREATE TABLE hash_cluster_tab_8k
(number (2) id,)
txt1 tank (2000).
txt2 tank (2000).
tank (2000) txt3
)
CLUSTER hash_cluster_8k (id);
Begin
because loop me in 1.5
Insert in the values of hash_cluster_tab_8k (i, 'x', 'x', 'x');
end loop;
end;
/
exec dbms_stats.gather_table_stats (WATERFALL of the USER 'HASH_CLUSTER_TAB_8K' = > true);
Now, if I try to access the folder with id = 1 - it shows 2 I / O (cr = 2) instead of the single e/s as provided in a hash cluster.
Rows Row Source operation
------- ---------------------------------------------------
1 ACCESS HASH_CLUSTER_TAB_8K HASH TABLE (cr = 2 pr = 0 pw = time 0 = 0 US)
If I run the query, even after the creation of a unique index on hash_cluster_tab (id), the execution plan specifies access hash and single e/s (cr = 1).
This means that for a single e/s in a single table hash cluster, we create a unique index? It will not create an additional burden to maintain an index?
What is the second I/o necessary for in the case where a unique index is absent?
I would be very grateful if gurus could explain this behavior.
Thanks in advance...user12288492 wrote:
I ran the query with all 5 id values and the results have been more confusing.During the first inning, I had VC = 2 for two values of keys, the Czech Republic rest = 1

In the third set, I had VC = 1 for all values of keysThe effects vary depending on the number of previous runs and the number of times you reconnect.
The extra CR is a cleansing of the block effect. If you check the access of the buffer (events 10200-10203), then you can see the details. Simplistically, if you create your data, then connect and interrogate one of the lines (but not id = 5, because that will be cleaned on the collection of statistics) you should be able to see the following numbers:cleanouts only - consistent read gets 1 immediate (CR) block cleanout applications 1 commit txn count during cleanout 1 cleanout - number of ktugct calls 1 Commit SCN cached 1 redo entries 1 redo size 80On the first block visited, Oracle made a visit to buffer to untangle a YVERT cleaning (ktugct - get the commit time). This cleans up the block and caches the acquired RCS. The rest of the blocks that visit you in the same session should not be cleaned because the session can use the updated SNA caching to avoid needing a cleanup operation. Finally all the blocks will have been cleaned up (which means that they will be written to the disk) and the extra CR stops happening.
There is a little quirk - drain plug seems to apply to the format block calls - and I do not understand why this was did not each row inserted thereafter.

(2) each table has about 2 million lines
What is the best way to create a single table with all unique key-values of all these paintings? The following two queries work up to about 150 + tables

Why the hell you have 250 + tables pair key / value?
Why the hell you want to group them in a table containing one row per key?
You could do a pivot of all the tables, not part. something like:
with t1 as ( select 1 as key, 'a1' as val from dual union all select 2 as key, 'a1' as val from dual union all select 3 as key, 'a2' as val from dual ) , t2 as ( select 2 as key, 'b1' as val from dual union all select 3 as key, 'b2' as val from dual union all select 4 as key, 'b3' as val from dual ) , t3 as ( select 1 as key, 'c1' as val from dual union all select 3 as key, 'c1' as val from dual union all select 5 as key, 'c2' as val from dual ) select key, max(t1val), max(t2val), max(t3val) FROM (select key, val t1val, null t2val, null t3val from t1 union all select key, null, val, null from t2 union all select key, null, null, val from t3) group by keyIf you can do it in a single query, Union all 250 + tables, you don't need to worry about chaining or migration. It may be necessary to do this in a few passes, depending on the resources available on your server. If so, I would be inclined to first create the table, with a larger than normal free percent, making the first game as a right inset and other pass or past as a merger.
Another solution might be to use the approach above, but limit the range of keys with each pass. So pass we would have a like predicate when the key between 1 and 10 in every branch of the union, pass 2 would have key between 11 and 20, etc. In this way, everything would be straight inserts.
That said, I'm going back to my second question above, why the hell you want or need to do that? What is the company you want to solve. There could be a much better way to meet the requirement.

For a single table import failed...
Hello
On the production server, I reported a user db, let's call it PRD_USER, with tablespace PRD_TBL default.
On the development server, I reported a user db, let's call it PRD_USER, with tablespace DEV_TBL default.
On the production server, I use the db of exp utility to import as:
IMP System/Manager of the user PRD_USER touser = PRD_USER = ignore = file_name = «...» ' log = «...» ».
Succeeds the import for about 25 tables and indexes and constraints, but it fails for a single table with the error: {I don't remember the error ORA- and I do not have access currently} DEV_TBL tablespace does not exist.
Of course this tablespace does not exist on production env. But how this problem arises because the default tablespace for the user is not DEV_TBL but PRD_TBL...?
Do you have any idea what can be the cause and how can I overcome this problem when importing...? {Note: I gave a temporary solution... take the table creation sql script leaving aside the reference of the tablespace "DEV_TBL"}.
The two servers work in exactly the same version of DB...
Note: I use DB 10g v.2
Thank you
SIMIf the table has Partitions, import strives to create the Partitions (in the CREATE TABLE statement) on the original table space.
OR there is a LOB segment in the table import strives to create on the original table space.

If I have the two LOV in the same table then how to connect when I select first and second LOV value also change?
My two fields are FLOW AND DR_NAME
FLOW = ACCT_ID
DR_NAME = ACCT_NAME
I created with success of LOV for these fields.
First LOV gives acct_id in the debit field and second LOV gives the value of acct_name to dr_name.
How can I report these lov, it's that when I change my acct_id then acct_name also change
I have these two tables

so, instead of this second ActId, choose ACCT_NAME:
