• analyze the differences between the 2 tables

  Hi all
  I have two tables, more or less the same. Suppose that the tables are the same for now (same columns, data types).
  One contains lines that are not in the second, the second contains documents that are not in the first table.
  How can I write a select statement would separate the lines 2 and not 1, lines 1 and not 2 and the municipality.
  I've already solved it by a bit of PL/SQL code, however, I'm looking for something elegant...
  
  Thank you

  Use less and union.

  I think that I read it wrongly...

  for joint - intersect
  for diff - less
  for the union to diff - union and less

• Difference between the nested table and an associative array

  Hello
  While going through the link http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96624/05_colls.htm
  I came across the statement that
  Nested tables can be stored in a column of data, but of associative arrays
  
  So I tried the following statement for the associative arrays where he works

  create type t_nm is table of number index by binary_integer

  The t_nm of type above name is stored in USER_TYPES.
  
  
  So how can we say that associative arrays can not be stored in DB.
  
  Please correct me if I'm wrong.
  
  Thank you

• What is the difference between the type of table and view?

  Hello world.

  What is the difference between the type of view and table that we can set using SQL statement such as: "tab type is table of...» » ?

  A view is a stored query.

  An array type is a construction of PL/SQL.

  Hello

  PER_PEOPLE_F is the base table for the employee master data.
  HR_EMPLOYEES_ALL_V is just a view on that data (only the employee with trust and now activ data).

  I suggest using the PER_PEOPLE_F (but in this table, terminated or future employee are also).

• Difference between the timings

  Hello

  I have a table like timings list both moves day and night.

  And saw the time (varchar) column and a time (varchar).

  difference between the timings

  in the time of expiration time

  case 1 (day shift): 06:00:00 23:00

  case 2(Night Shift) 23:00 07:00

  Hello

  You want solutions that work?  Then make sure that the CREATE TABLE and INSERT statements you post too much work.  Test (and, if necessary, correct) them before posting.  Among other errors, the INSERT statements that you posted have unbalanced parentheses, and you try to put 5 values in 4 columns.  Also, do not attempt to INSERT a value of VARCHAR2, as August 19, 2014 ", in a DATE column."  TO_DATE allows to convert strings to DATEs.

  If, for example, in_time =' 06:00:00 'and out_time = 23:00:00 ', is that 17 hours?  How do you know that it's not 41 hours or 65 hours?

  If you are assuming that this out_time is in_time (if is a moment later) the same day or the next day (although out_time is earlier than in_time), then you can do something like:

  (TO_DATE (outtime, 'HH24:MI:SS')

  -(TO_DATE (respondent, 'HH24:MI:SS')

  -CASE

  WHEN respondent<=>

  THEN 0

  1. OTHER

  END

  )

  ) * 24

  Notice how much more complicated it is that expression I posted earlier, which is what you would need if you used DATE columns.  It will therefore be slower, as well.  Also, this can trigger an error and do not return results at all if there is typo in one of the in_time or out_time columns.  As mentioned previously, it makes no allowance for 24 hours changes (or), and there are 3 columns in your table, instead of 2.

• difference between the view and the procedure

  Hi Master,

  Today I received a request from my senior technical leader... !!

  Q > what is the difference between the view and the procedure?

  I got response like this...

  A view represents the logic of one or more tables/views. It won't take no place in db... It is a virtual table, query will only store in db... useful

  for safety... If the main table has obtained changes... automatically discovers also change... etc.

  Proecudure is a db object will be performs a perticular action... It may or may not return values. ?

  But somehow, he isn't happy... He expects more... .very close view of diff. b & w and procedure.

  Please explain it to me...!

  Hi Blu,

  Thanks for your replies...! But we think if notice and procedure will be the same no matter what point of view? Both are the same? If Design view... We can create a stored procedure?

  How a view and procedure may do the same thing?  They are two different things with different objectives.  You use the correct one depending on what you want to achieve; they are not interchangeable.

  And another question...!

  (Q) how you will store Japan, characters of China in a database table? will there be a new feature in Oracle 11 g?

  (A) I use dbms_lob package? Japan/China characters are multi byte characters... so we can use the nclob data type?

  is this correct... ?

  No, it not there no novelty in Oracle 11 g for the storage of Japanese or Chinese characters, because there is already a feature for their storage in previous versions as well.  It is determined by the parameters characterset and nationality that you use when you create the database.

  Why would you choose to store them in a LOB using DBMS_LOB?  Yes, they have multibyte characters, but if you have configured your database for the correct character sets, for example using UTF - 8, then you can store the characters in VARCHAR2, like any other language.  The only difference is that the storage of 4000 bytes limit still applies, so you maybe isn't able to store 4000 multibyte characters in a varchar2 column 4000 single-byte, it can be as little as 1000 characters if they are all characters in 4 bytes.  (Note: 12 c limit in SQL can be increased up to 32,767 characters, to harmonize it with variable varchar2 PL)

  Abdetu...

  I don't know exactly what you're asking. The query

  UPDATE WH_T_ITEMS A
     SET BALANCE_QTY =MAX(ITEM_QTY)
   WHERE STORE_ID = V_STORE_ID
     AND ITEM_SERIAL = V_ITEM_SERIAL   ;
  

  is not valid SQL from Oracle. As MAX aggregate functions cannot be used in a query like that because Oracle has no idea what you aggregate by. There is nothing preventing Oracle to change the syntax of the SQL language to allow an aggregate be used this way, but there is usually no reason to extend the SQL language like that.

  You can assign the result of a query that included a total of BALANCE_QTY column, i.e.

  UPDATE WH_T_ITEMS A
     SET BALANCE_QTY = (SELECT MAX(ITEM_QTY) FROM <> WHERE <>)
   WHERE STORE_ID = V_STORE_ID
     AND ITEM_SERIAL = V_ITEM_SERIAL   ;
  

  I think I mentioned in some of your previous discussions, a data model where you have a table of ELEMENTS that has an ITEM_QTY and the BALANCE_QTY looks suspicious. You assign the value of the ITEM_QTY column to the BALANCE_QTY on the same line does only increase anxiety.

• How to read the voltage difference between the 2 pins of a RS232?

  Hi, I'm new in this field and I'm having a problem in the acquisition of data from a RS232 port. In fact, I don't know if it is possible to do.

  What I would do, is to read the voltage difference between the two pins of the port. It's because I want to measure the temperature (and save the data) in a very simple way. I have 6 thermocouples and I thought weld at the different pins of the RS232 interface and acquire analog signals in mV with the computer. Then, I would use a thermometer to calibrate the values.

  Is it possible to do? How? I searched a lot but I can't find any tutorial or similar to this example...

  No, it is not possible to do it with the serial port. The port is not an A/D converter. A simple RS-232 tutorial will tell you that the port is binary in nature.

• difference between the real time module and module fpga

  Hi experts,

  I was wondering if someone could tell me the difference between the FPGA and the module in real time (in short).

  My understanding is that the FPGA module facilitates code LV that can then be designed for the specific advice of RIO, I have used this a bit in the past.

  The real time module, I'm a little more unsure about, all I know is that it allows the creation of a 'real time' i.e. deterministic environment.

  My request is this: I wish I had several control loops running on two tables of RIO, with the host PC mainly used for recording data and user interface. I see that I have no need of RT on the host (Win XP should be good).

  Do I need the RT module?

  You are right.  In the scenario you describe, you won't need to LabVIEW RT. LabVIEW RT is used to create a deterministic execution on specific targets for intel such as the PXI-8106 and PXI-8108.  You can still use strings and floating point on RT.

• What is the difference between the IO and line?

  Hi all

  I'm using Labview 7 and in my mahcine I have an installed 6013 card. However, there was an interface card designed by someone else long ago, on the table, only AO0, AO1,..., A07, DIO0, DIO1,..., DIO7 were printed. In the program, I saw some code to write to digital Line.vi allows you to send data to the digial io. Say that I write for DIO 3, so I understand here DIO 3 means the channel of e/s 3, but online? What is the difference between the channel and the line? When I write the data to a single channel of e/s, are us wriitng a byte or a bit of it? Thank you.

  A channel is usually used with inputs/outputs analog.  Each AI or AO is a string.

• What is the difference between the VI of the histogram and the General histogram VI?

  Hello

  I did a google search and forum for this and came up empty. I would like to know if there should be a difference in how the work of both?

  I ask because I gave exactly the same table both X and was two different results, unless I also specified the interval bins / # to be equal for each of them. (level for the VI histogram and #bins for the general histogram VI)

  It also means I want to know the difference between the intervals and #bins? They are the same thing with different names just?

  It's more of a general idea on how the two screws work to obtain a specific solution to a problem, anyway, so any help is appreciated

  Thanks in advance.

  Pladio wrote:

  Thank you. No idea why the same data would give different histograms when the specification is not garbage?

  Yes.

  The normal VI, if you do not connect the entry "interval", will give you 10 bins, becaue that entry is set by default to 10.

  The advanced VI, if you do not connect the "#bins" of entry, will give you a number of bins from comment how are made, or the size of the incomming table. This number is 1 + 3.3 log n, where n is the size of the array. This is called rule of Sturges, and is more or less explained in the programming of this VI. Open it and look at it.
