How to partition a table

Hi all

I use oracle 10g R2 64 bits on 64-bit windows server 2008.

I am facing problem with a table, which seems to be supposed to be a table partitioned, because it expects the 80000 lines per year.

This is the normal table for the table script

create table Leave_Request (Leave_request_id number primary key,
                                          emp_id number references emp(emp_id) not null,
                                          leave_type_id number references leave_types(leave_type_id) not null,
                                          leave_apply_date date not null,
                                          leave_from_date date not null,
                                          leave_to_date date not null,
                                          remarks varchar2(3000));

What is known, is that an index would be created to Leave_request_id automatically.

now, my question is how to partition? How to create its index score?

I read a few pages on the partitions and the notion of partitioning, but always confused with my situation.

an example would be much appreciated.

Thank you.

First of all you must decide the column on which you want to partition in function. As you expect 80000 lines per year, you can partition it on the date column for example leave_apply_date with the partition of the RANGE.

What is known, is that an index would be created to Leave_request_id automatically.

No you need write explicitly create index statement to create indexes.

now, my question is how to partition?

Here is an example:

CREATE TABLE sales_range

(salesman_id NUMBER (5),)

salesman_name VARCHAR2 (30),

Sales_Amount NUMBER (10),

Sales_Date DATE)

PARTITION OF RANGE (sales_date)

(

PARTITION sales_jan2000 VALUES LESS THAN (TO_DATE('02/01/2000','MM/DD/YYYY')),

PARTITION sales_feb2000 VALUES LESS THAN (TO_DATE('03/01/2000','MM/DD/YYYY')),

PARTITION sales_mar2000 VALUES LESS THAN (TO_DATE('04/01/2000','MM/DD/YYYY')),

PARTITION sales_apr2000 VALUES LESS THAN (TO_DATE('05/01/2000','MM/DD/YYYY'))

);

How to create its index score?

Just add keyword LOCAL at the end of the create index example statement

CREATE INDEX abc_ix_01 ON test (last_update_time) LOCAL app_index TABLESPACE;

    The first thing you need to do is to create a USB stick recovery. You will need a 16 GB flash drive.

    Be aware that any chenges in the recovery partitions will result in the loss of the ability to recover start-up or inside windows menu. Do not save anything in the score!

    Why do you say that you can not even partition your C: partition in disk management?

    Your operating system is partitioned into GPT format with UEFI support.  That means the main four-partition MBR partitions type limit does not apply. If you reduce the C: partition, you should be able to create multiple partitions without problem. Do not use the same drive letter that has the recovery partition.

    I highly recommend that you use a cloning software to clone a copy of your SSD, as he is currently in an external hard drive. I recommend using Backup software Paragon & Recovery 15.

    WARNING: since I'm a Microsoft MVP, Paragon Software provides copies me of reviewer of their software for me to see and use. I had great results with their backup products. Power completely backup hard drives allows me to really put the loans of HP product through the grinder.

    Why not install Linux under VM?  No partitioning or boot sector don't risk ca OSX.  And unless you plan to video editing in Linux, the "virtual video driver" should be sufficient for all operations.

    By the way... VM runs simultaneously with OSX to share information.  Virtual machine image can live on an external drive, so DO not take room away from OSX.

    I've not seen / heard of successful use of the flash drive for recovery purposes. The default software using optical disk, when I used it on my G580.

    If your laptop does not have a CD / DVD burner, you may need to contact them directly to discuss this option.

    As to where he is? It is a hidden partition on the hard drive, is usually not accessible.

    Cloning the hard drive can not return to that partition hidden - it would be a little bit the clone of the drive to work.

  • How to build a table inside a loop

    Hello world

    I have a fundamental question on labview. I would like to create a table in a loop 'for' in this way:

    inside the loop, if a condition named 'A' is true, then I add a new value to the first column of the table.  Otherwise, I have create a new column and start adding values in this column when the condition 'A' is checked, etc.

    I put an example of a VI when the 'A' condition is "improving the loop + 1 is not divisible by 5" and the values in the tables are to increase the loop + 1. The loop stops when the increment = 25.

    In this example, I have a single column with the values [1 2 3 4 6 7 8 9 11 12 13 14 16 17 18 19 21 22 23 24]

    while I wish I had a table of 5 columns:

    1 6 11 16 21

    2 7 12 17 22

    3 8 13 18 23

    4 9 14 19 24

    Note that this is just an example. More generally, the table may contain columns of different lengths.

    Thanks for your response

  • How to build a table of TDMS file open

    Hello

    Examples NI TDMS - Express write data .vi (time domain), I can build a PDM file with 2 channels (sine and square waveforms) data, which are stored as test.tdms.

    Using Express read .vi data (time domain), 2 channels of waveform data are read. How to build a table later? How to separate the 2 channels of data in the tables 1-2 and manipulate the data using table functions?

    For example,.

    I want to collect 100 from index100 between channel 0 and their average. I want to take 50 samples from the channel 50 1 index and double each element.

    Thank you for your help.

    Bing@NCL

    Hey Bing.

    You can perform operations on different channels in the 2D table using the table to index. This will allow you to choose the channel to operate on, then you can perform the operation inside a loop on each element. In the included code snippet, I used a shift register to find the total cumulative values in channel 0 and then divided by the number of samples.

    I recommend you read some tutorials LabVIEW and bases of knowledge on topics that are related to yours. These could help a lot.

    I hope that my suggestions help,

  • Someone knows how to fill a table more quickly?

    Hey everybody,

    I created a program that displays a graph of intensity, as well as a histogram of the values of intensity on a chip 1024 x 1024 (dimension X - Y). Currently, the program works well, the histogram takes FOREVER to fill but I was wondering if there is a way to increase the speed of everything including all points of data 1024 x 1024 = 1048576. Thank you!

    I realize complete the table of pixel by pixel is not the best route, but I'm not sure how to take the 2D table and use the intensity of each (x, y) point in a histogram.

    Thanks, to emphasize that I have no need to call the histogram works every time (rookie mistake), but as I said, I'm still not sure how to the 2D table in the histogram.

    And I reset the histogram when finished filling because I need to reset to see the changes for when I change (if necessary) camera exposure time. I have also attached my code.

  • How to index a table on multiple sites?

    Hello

    How to index a table on multiple sites?

    I searched this issue and was not able to find the answer. I understand that it can be done with loops, but I don't know how.

    I use the detector of crete vi for frequency domain data collected a VNA (s2p) file. The products contain a table of amplitudes and a table of locations. The problem is that the locations refer to the index of table of amplitude, which is not the same as the frequency. My idea is that I can use this output of the places table to index the frequency to the detected peak frequencies table and then draw these, as well as some analysis data and manipulation on them. Currently, I can do this only by consulting table on the front panel.

    The entrance to the peak detector is currently a table 1 d of the scale (what is the problem?).

    I also looked at the supply frequency & estimate VI, but this VI seems only exit of scalar data for the largest peak, not exactly what I'm looking for.

    Thanks for your help.

    You have a second table for the tested frequency?  If so, then you are right that you just need to index this table with the indexes by the Ridge detector.  Use a loop for.  Automatic index to the index, use index in array to get the value of the frequency and autoindex on frequencies.

  • How to create a table in if/else or structure without 0-case?

    Hello

    I tried to do for a while now.

    I only managed to think about this in three ways:

    1. (what I'm doing right now create the table through a loop for, fills the table in automatic indexing.) Filled it with many of if true and with a '0' if the value false. The idea was to remove the 0 later in the code. However, this seems very inefficient.

    2 make use of a registry change, which automatically adds the correct number of a table. The problem is that the table will keep growing and growing and at the very least would enormously slow down my program. At worst, it would break.

    So my question is: how to create a table that if a comparison is true, it puts the item in and if not, it does nothing?

    I have attached a PNG of my code snippet.

    Kind regards

    David.

    If you want to only affect exactly as much memory as you need for the table, you can count the number of true elements in the table of Boolean everything first and then assign one of exactly this size. In this way, you are more memory and time-efficient whether overuse (such as allocation of an array of I32 as big as the whole table boolean) or underallocating (from zero element and let it grow automatically whenever you add on).

    Count the true values, allocate an array only the great and then replace each value in this new table with indexes / "I ' value where the real exists." An excerpt from VI:
