One table or many?
I'm just starting to re-write a web app and looking at the
database one of the tables is getting quite large (field wise)
The table in question is for room attributes but is used in 3
different apps. It's not particularly large in either direction and
isn't high demand on records so I suspect the overall answer to
this is in this case it doesn't matter but I'd be interested in
people's thoughts.
Do i have one large table with approx 90 fields which has
less query load as I'm not joining tables so much or do i have 3
tables (one for the basic room details (5-10 fields) one with the
equipment in the room (30 fields) etc. which would need joining
each time I used them but would be easier for writing queries as
select * would be appropriate most of the time and would arguably
be easier to maintain and modify (for both db and queries)?
The floor is now open!
Wow, hard to answer. What about your data model? Do you have
data in your table that is not normalized? Single table
"spreadsheet-like" database tables are an indicator of a missing or
inadequate data model and design. However, it is almost impossible
to know for sure without knowing the nature of your data, how your
entities relate, and what attributes are associated with these
entities, etc.

One to Many with multiple tables on One side and one table on Many side
Sorry for the confusion in the title. Here is my question. In my program, I have 2 different tables which store 2 different type of entities. Each one of entities has a list of attachments which I stored in a common attachment table. There is a one-to-many relationship between entity tables and attachment table.
ENTITY_ONE (
ID
NAME
ENTITY_TWO (
ID
NAME
ATTACHMENTS (
ID
ENTITY_ID
ATTACHMENT_NAME
ENTITY_ID in ATTACHMENTS table is used to link attachments to either entity one or entity two. All IDs are generated by one sequence. So they are always unique. My question is how I could map this relationship into EntityOne, EntityTwo and Attachment JAVA class?For EntityOne and EntityTwo you can just define a normal OneToMany mapping using the foreign key.
Are you using JPA, or the TopLink API? JPA requires a mappedBy for the OneToMany, so this may be more difficult. You should be able to just add a JoinColumn on the OneToMany and make the column insertable/updateable=false.
For the attachment, you could either map the foreign key as a Basic (DirectToFieldMapping) and maintain it in your model, or use a VariableOneToOne mapping in TopLink (this will require the entities share a common interface).

How to get missing records from one table
I have one table with many records in the table. Each time a record is entered the date the record was entered is also saved in the table.
I need a query that will find all the missing records in the table.
so if I have in my table:
ID Date Location
1 4/1/2015 bld1
2 4/2/2015 bld1
3 4/4/2015 bld1
I want to run a query like
Select Date, Location FROM [table] WHERE (Date Between '4/1/2015' and '4/4/2015') and (Location = bld1)
WHERE Date not in
(Select Date, Location FROM [table])
and the results would be:
4/3/2015 bld1
Thank youDo you have a table with all possible dates in it? You can do a left join from that to your above mentioned table where the right side of the join is null. If you don't have a table with all possible dates you could user a numbers table.
Below is one way to achieve what you want with a numbers table...
DECLARE @Table table (ID Int, DateField Date, Location VarChar(4))
DECLARE @RunDate datetime
SET @RunDate=GETDATE()
IF OBJECT_ID('dbo.Numbers') IS NOT NULL
DROP TABLE NUMBERS
SELECT TOP 10000 IDENTITY(int,1,1) AS Number
into Numbers
FROM sys.objects s1
CROSS JOIN sys.objects s2
ALTER TABLE Numbers ADD CONSTRAINT PK_Numbers PRIMARY KEY CLUSTERED (Number)
INSERT INTO @Table (ID, DateField, Location)
VALUES ('1','20150401','bld1')
,('1','20150402','bld1')
,('1','20150404','bld1');
WITH AllDates
as
SELECT DATEADD(dd,N.Number,D.StartDate) as Dates
FROM Numbers N
cross apply (SELECT CAST('20150101' as Date) as StartDate) as D
select *
from AllDates AD
left join @Table T on AD.Dates = T.DateField
where ad.Dates between '20150401' and '20150404'
AND T.ID IS NULL

How to view one table used percentage in sqlplus?
if the table only one record in dba_free_space,then use

but one table have many records in dba_free_space,
how to display this table's used percentage?DBA_FREE_SPACE displays free extents in all tablespaces: there is no direct relationship with any given table.

Copying many rows from one table to another
Could anyone tell me the best way to copy many rows (~1,000,000) from one table to another?
I have supplied a snipit of code that is currently being used in our application. I know that this is probably the slowest method to copy the data, but I am not sure what the best way is to proceed. I was thinking that using BULK COLLECT would be better, but I do not know what would happen to the ROLLBACK segment if I did this. Also, should I look at disabling the indexes while the copy is taking place, and then re-enable them after it is complete?
Sample of code currently being used:
PROCEDURE Save_Data
IS
CURSOR SCursor IS
SELECT ROWID Row_ID
FROM TMP_SALES_SUMR tmp
WHERE NOT EXISTS
(SELECT 1
FROM SALES_SUMR
WHERE sales_ord_no = tmp.sales_ord_no
AND cat_no = tmp.cat_no
AND cost_method_cd = tmp.cost_method_cd);
BEGIN
FOR SaveRec IN SCursor LOOP
INSERT INTO SALES_ORD_COST_SUMR
SELECT *
FROM TMP_SALES_ORD_COST_SUMR
WHERE ROWID = SaveRec.Row_ID;
RowCountCommit(); -- Performs a Commit for every xxxx rows
END LOOP;
COMMIT;
EXCEPTION
END Save_Data;
This type of logic is used to copy data for about 8 different tables, each containing approximately 1,000,000 rows of data.Your best bet is
Insert into SALES_ORD_COST_SUMR
select * from TMP_SALES_ORD_COST_SUMR;
commit;

How many primary key fields allowed for one table?
hi,
when i creating a table , how many primary key fields are allowed for one table.
please any one give ans
thanksJust checked it, Its 255, not 155. You can have as many key fields as you want, but you can not go over the 255 byte length for the total of all key fields. You will get a warning for over 120, as it says that there is limited functionality with a key over 120 in length.
Again, this is a total length of all key fields.

If you have more than one trigger that fires at the same time (for example "BEFORE INSERT OR UPDATE ... FOR EACH ROW"), ask yourself why you want or need 2 separate triggers, rather than one (which maybe calls two sparate procedures). -
How to get the data from one table and insert into another table
Hi,
We have requirement to build OA page with the data needs to be populated from one table and on save data into another table.
For the above requirement what the best way to implement in OAF.
I understand that if we attach VO object instance to region/page, we only can pull and put data in to only one table.
ThanksYou can achieve this in many different ways, one is
1. Create another VO based on the EO which is based on the dest table.
2. At save, copy the contents of the source VO into the dest VO (see copy routine in dev guide).
3. commiting the transaction will push the data into the dest table on which the dest VO is based.
I understand that if we attach VO object instance to region/page, we only can pull and put data in to only one table.
if by table you mean a DB table, then no, you can have a VO based on multiple EOs which will do DMLs accordingly.Thanks

How to read LONG RAW data from one table and insert into another table
Hello EVERYBODY
I have a table called sound with the following attributes. in the music attribute i have stored some messages in the different language like hindi, english etc. i want to concatinate all hindi messages and store in the another table with only one attribute of type LONG RAW.and this attribute is attached with the sound item.
when i click the play button of sound item the all the messages recorded in hindi will play one by one automatically. for that i'm doing the following.
i have written the following when button pressed trigger which will concatinate all the messages of any selected language from the sound table, and store in another table called temp.
and then sound will be played from the temp table.
declare
tmp sound.music%type;
temp1 sound.music%type;
item_id ITEM;
cursor c1
is select music
from sound
where lang=:LIST10;
begin
open c1;
loop

exit when c1%notfound;
end loop;
CLOSE C1;
insert into temp values(temp1);
item_id:=Find_Item('Music');
go_item('music');
play_sound(item_id);

I have a table with many LONG fields (28). So far, everythings works fine.
However, if I add another LONG field I cannot insert a dataset anymore

It solves my problem. Thanks a lot. -- I hardly can believe that this is all needed to solve the bug. This may be the reason why I have not given it a try.

Since explicitely specifying all values for an insert is a good idea anyhow (you can see directly, what value the new tupel will have), you may want to change your code to this.

You are right. This table looks a bit strange. The story behind it is: Each crystal report in the application has a few textblocks which are the same for all the e.g. persons the e.g. letter is created for. Principally, the textblocks could be directy added to the crystal report. However, as it is often the case, these textblocks may change once in a while. Thus, I put the texts of the textblock into this "strange" db table (one row for each report, one field for each textblock, the name of the report is given by "ztb_nameofreport"). And the application offers a menue by which these textblocks can be changed. Of course, the fields in the table could be of type CHAR, but LONG has the advantage that I do not have to think about the length of the field, since sometime the texts are short and sometimes they are really long.
(These texts would blow up the sql select command of the crystal report very much if they were integrated into the this select command. Thus it is realized in another way: the texts are read before the crystal report is loaded, then the texts are "given" to the crystal report (by its parameters), and finally the crystal report is loaded.)

The customer still has Win98 clients. MaxDB odbc driver 7.5.00.26 does not work for them. I got the hint to use odbc driver 7.3 (see [lists.mysql.com/maxdb/25667|lists.mysql.com/maxdb/25667]). Do MaxDB 7.6 and odbc driver 7.3 work together?
All Win98 clients may be replaced by WinXP clients in the near future. Then, an upgrade may be reasonable.

In the first MaxDB version I used, schemas were not available. I haven't changed it afterwards. Is there an easy way to "move an existing table into a new schema"?

Number of Records in one table
Hi All,
Can anybody let me know that in Oracle9i lite database, one table can have how many records. I mean is their any restriction on maximum number of ROWs for a table, like Palm database (PDB files) has a restriction that one table can have maximum 64000 rows.
Is the same thing happen with Oracle lite database also
Thansk in advance.We have had several tests of hundreds of thousands of rows using 9iLite on a PocketPC host. The upper bound appears to be based upon the physical limit of the host and not 9iLite.

[AS] How to test the presence of at least one table?
Hello everyone,
I would like to test for the presence of at least one table in a document before starting a process (on edge strokes).
I found this, but I do not know if this is really effective:
set CountOfTables1 to count of tables of every story
set CountOfTables2 to every table of every story
The first gives me a list of the number of table in each story; the second gives me the objects reference of every table.
Is there another way?
TIA.
Oli.Marc
The test I did for nested tables stank (table pasted in rectangle and that rectangle pasted in a table ). It does not work for nested tables
I tested .isValid and it's a lot slower.
Uwe
Yes, I noticed that difference after posting my eeakk comment.
Using slice(0) after the getElements can make a big difference but still the simple length going to be quicker in this case.
Also the getElements without the slice(0) will return "too many elements" if there are to many elements (between 1500 - 15,000).
On the other hand for repeated access of the variable (looping) it's as know normally quicker to use the getElements().slice(0).length than just length
In summary
1) Your anyItem() method is going to be very quick on a document which has a high ratio of stories containing tables.
2) Although your method could and possibly probably be 100 times quicker than mine I would definitely use my method in terms of typing time and space verses the 1/2 second it might save on execution time per 10,000 tables.
3) The only accurate method (in this thread) for counting the tables including nested and footnotes is Marc's Grep method.
So I guess the 3 of us can share first place.
I just wonder if using the same technique as Marc used in our discussion sometime back on nested buttons might get to a quick count than using the Grep method here.
Clearly needs to be repeated on different types of document setups one can try the below
if (!app.properties.activeDocument) {alert ("Really!?"); exit()};
var scriptCount = 1;
// Script 1 table.length
var doc = app.activeDocument,
start = Date.now(),
t = doc.stories.everyItem().tables.length,
finish = Date.now();
$.writeln ("\rtable.length Script (" + scriptCount++ + ") took " + (finish - start) + "ms\r" + ((t) ? t + " Table" + ((t>1) ? "s" : "") : "Diddlysquat"));
// Script 2 getElements
var doc = app.activeDocument;
var start = Date.now();
var t = doc.stories.everyItem().tables.everyItem().getElements().length;
var finish = Date.now();
$.writeln ("\rgetElements Script (" + scriptCount++ + ") took " + (finish - start) + "ms\r" + ((t) ? t + " Table" + ((t>1) ? "s" : "") : "Diddlysquat"));
// Script 3 getElements.slice(0)

P.s.
Marc,
A bit of homework. I didn't test it on the above but I found the your highRes function trimmer seems to have a large favoritism to the first function to compare.
I was testing 2 prototypes and swapping the order swapped the result. One can make the prototypes the same and see the time difference. -
Query performance on same table with many DML operations
Hi all,
I am having one table with 100 rows of data. After that, i inserted, deleted, modified data so many times.
The select statement after DML operations is taking so much of time compare with before DML operations (There is no much difference in data).
If i created same table again newly with same data and fire the same select statement, it is taking less time.
My question is, is there any command like compress or re-indexing or something like that to improve the performance without creating new table again.
Thanks in advance,
PalTry searching "rebuilding indexes" on http://asktom.oracle.com. You will get lots of hits and many lively discussions. Certainly Tom's opinion is that re-build are very rarley required.
As far as I know, Oracle has always re-used deleted rows in indexes as long as the new row belongs in that place in the index. The only situation I am aware of where deleted rows do not get re-used is where you have a monotonically increasing key (e.g one generated by a seqence), and most, but not all, of the older rows are deleted over time.
For example if you had a table like this where seq_no is populated by a sequence and indexed
seq_no NUMBER
processed_flag VARCHAR2(1)
trans_date DATEand then did deletes like:
DELETE FROM t
WHERE processed_flag = 'Y' and
trans_date <= ADD_MONTHS(sysdate, -24);that deleted the 99% of the rows in the time period that were processed, leaving only a few. Then, the index leaf blocks would be very sparsely populated (i.e. lots of deleted rows in them), but since the current seq_no values are much larger than those old ones remaining, the space could not be re-used. Any leaf block that had all of its rows deleted would be reused in another part of the index.

How to improve speed of queries that use ORM one table per concrete class
Hi,
Many tools that make ORM (Object Relational Mapping) like Castor, Hibernate, Toplink, JPOX, etc.., have the one table per concrete class feature that maps objects to follow structure:
CREATE TABLE ABSTRACTPRODUCT (
ID VARCHAR(8) NOT NULL,
DESCRIPTION VARCHAR(60) NOT NULL,
PRIMARY KEY(ID)
CREATE TABLE PRODUCT (
ID VARCHAR(8) NOT NULL REFERENCES ABSTRACTPRODUCT(ID),
CODE VARCHAR(10) NOT NULL,
PRICE DECIMAL(12,2),
PRIMARY KEY(ID)
CREATE UNIQUE INDEX iProduct ON Product(code)
CREATE TABLE BOOK (
ID VARCHAR(8) NOT NULL REFERENCES PRODUCT(ID),
AUTHOR VARCHAR(60) NOT NULL,
PRIMARY KEY (ID)
CREATE TABLE COMPACTDISK (
ID VARCHAR(8) NOT NULL REFERENCES PRODUCT(ID),
ARTIST VARCHAR(60) NOT NULL,
PRIMARY KEY(ID)
there is a way to improve queries like
SELECT
pd.code CODE,
abpd.description DESCRIPTION,
DECODE(bk.id,NULL,cd.artist,bk.author) PERSON
FROM
ABSTRACTPRODUCT abpd,
PRODUCT pd,
BOOK bk,
COMPACTDISK cd
WHERE
pd.id = abpd.id AND
bk.id(+) = abpd.id AND
cd.id(+) = abpd.id AND
pd.code like '101%'
or like this:
SELECT
pd.code CODE,
abpd.description DESCRIPTION,
DECODE(bk.id,NULL,cd.artist,bk.author) PERSON
FROM
ABSTRACTPRODUCT abpd,
PRODUCT pd,
BOOK bk,
COMPACTDISK cd
WHERE
pd.id = abpd.id AND
bk.id(+) = abpd.id AND
cd.id(+) = abpd.id AND
abpd.description like '%STARS%' AND
pd.price BETWEEN 1 AND 10
think in a table with many rows, then exists something inside MaxDB to improve this type of queries? like some anotations on SQL? or declare tables that extends another by PK? on other databases i managed this using Materialized Views, but i think that this can be faster just using PK, i'm wrong? the better is to consolidate all tables in one table? what is the impact on database size with this consolidation?
note: with consolidation i will miss NOT NULL constraint at database side.
thanks for any insight.
ClóvisHi Lars,
i dont understand because the optimizer get that Index for TM at execution plan, and because dont use the join via KEY column, note the WHERE clause is "TM.OID = MF.MY_TIPO_MOVIMENTO" by the key column, and the optimizer uses an INDEX that the indexed column is ID_SYS, that isnt and cant be a primary key, because its not UNIQUE, follow the index columns:
indexes of TipoMovimento
INDEXNAME COLUMNNAME SORT COLUMNNO DATATYPE LEN INDEX_USED FILESTATE DISABLED
ITIPOMOVIMENTO TIPO ASC 1 VARCHAR 2 220546 OK NO
ITIPOMOVIMENTO ID_SYS ASC 2 CHAR 6 220546 OK NO
ITIPOMOVIMENTO MY_CONTA_DEBITO ASC 3 CHAR 8 220546 OK NO
ITIPOMOVIMENTO MY_CONTA_CREDITO ASC 4 CHAR 8 220546 OK NO
ITIPOMOVIMENTO1 ID_SYS ASC 1 CHAR 6 567358 OK NO
ITIPOMOVIMENTO2 DESCRICAO ASC 1 VARCHAR 60 94692 OK NO
after i create the index iTituloCobrancaX7 on TituloCobranca(OID,DATA_VENCIMENTO) in a backup instance and get surprised with the follow explain:
OWNER TABLENAME COLUMN_OR_INDEX STRATEGY PAGECOUNT
TC ITITULOCOBRANCA1 RANGE CONDITION FOR INDEX 5368
DATA_VENCIMENTO (USED INDEX COLUMN)
MF OID JOIN VIA KEY COLUMN 9427
TM OID JOIN VIA KEY COLUMN 22
TABLE HASHED
PS OID JOIN VIA KEY COLUMN 1350
BOL OID JOIN VIA KEY COLUMN 497
NO TEMPORARY RESULTS CREATED
JDBC_CURSOR_19 RESULT IS COPIED , COSTVALUE IS 988
note that now the optimizer gets the index ITITULOCOBRANCA1 as i expected, if i drop the new index iTituloCobrancaX7 the optimizer still getting this execution plan, with this the query executes at 110 ms, with that great news i do same thing in the production system, but the execution plan dont changes, and i still getting a long execution time this time at 413516 ms. maybe the problem is how optimizer measure my tables.
i checked in DBAnalyser that the problem is catalog cache hit rate (we discussed this at [catalog cache hit rate, how to increase?|;
) and the low selectivity of this SQL command, then its because of this that to achieve a better selectivity i must have an index with, MF.MY_SACADO, MF.TIPO and TC.DATA_VENCIMENTO, as explained in previous posts, since this type of index inside MaxDB isnt possible, i have no choice to speed this type of query without changing tables structure.
MaxDB developers can develop this type of index? or a feature like this dont have any plans to be made?
if no, i must create another schema, to consolidate tables to speed queries on my system, but with this consolidation i will get more overhead, i must solve the less selectivity because i think if the data on tables increase, the query becomes impossible, i see that CREATE INDEX supports FUNCTION, maybe a FUNCTION that join data of two tables can solve this?
