• Merge multiple columns into a single column?

  Hello
  
  I need to perform queries dynamically and the return values. I need to retrieve the values of the queries in a single column only by concatenating multiple columns. I can't use the PL/SQL in my scenario.
  is it possible to run a query and the result will be extracted in a single column (multiple column values must be concatenated)?
  
  Thank you

• subtract, divide into a single custom script calc

  I am very new to all this and have created a custom with the help of this community script.  I try to get the percentage increase, when a person gets a pay rise...

  My fields are Pay1 = old rate, funds2 = new rate, payer3 = amount of increase and Pay4 percentage increase.

  I have the script below in the Pay4 fields:

  var P1 = Number (this.getField("Pay1").value);

  var P2 = Number (this.getField("Pay2").value);

  If (P1 = 0) {P1 = 1}

  If (P2 = 0) {P2 = 1}

  var P3R = P1/P2 * 100;

  var PERC3NT = 100 - P3R;

  PERC3NT = PERC3NT / 100;

  this.getField("Pay4").value = PERC3NT;

  I noticed that if I replace "funds2' with 'Payer3' I get a smaller amount as the percentage.  I know I need to divide the difference of the old rate increased and the time by 100 to get the percentage.  I seem to be missing something because even when I change the rate to a dollar more my percentage does not seem fair.  Can help you.

  This is because you need to divide the new salary of old, not the other way around.

  I think that this code should work fine:

  var P1 = Number (this.getField("Pay1").value);

  var P2 = Number (this.getField("Pay2").value);

  If (P1 == 0 |) P2 == 0) {event.value = ""}

  else event.value = ((P2/P1)-1) * 100;

  You posted the SQL code. Not PL/SQL code.

  Group, but in the meantime, firstname and lastname.

  Of course, you will also need to group by firstname and lastname for this SQL query.

  With a Group of SQL, you have basically 2 types of values that can be returned:
  -the value of Group of
  -l' aggregated/calculated the value of this group

  If you could watch the first name and the last name by code:

  select
    code, MIN(firstname), MAX(lastname)
  from customer
  group by code
  

  You can see the number of unique name and surname by code:

  select
    code, COUNT(DISTINCT firstname), COUNT(DISTINCT lastname)
  from customer
  group by code
  

  Think of the clause group by in size (for example the code in the SQL above) and measures (calculations by code in the SQL above).

• Two foreign keys of a table in a single column

  Hi gurus

  I wonder that can we add two foreign keys of a table on a single column, I think the answer is, but what should be the reason behind this?

  Appreciate if someone there explain to me...

  Concerning

  Muzz

  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 FK

  But 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.

  Here is a sqlplus session illustrating; the last piece: I try inserting several lines in xxxx, only the last is accepted.

  SQL > CREATE TABLE PEOPLE (id NUMBER of the PRIMARY KEY, name VARCHAR2 (20 CHAR));

• Selection of Pixel single column, then paste...

  Hello

  This might look like a very unusual request, but I was upset to find the answer.

  In a given photographic image, I would choose a single pixel in each row of pixels, running up and down in a columnof a pixel.  Then, I want to eliminate (Cup) nothing else on the Web with the exception of the one column of selected pixels. From there, I would take the pixel selected in each line and copy the pixel color on each line on the left and right of the pixel selected.

  The end result is that I have a series of horizontal lines of pixels height of one color (based on the color of the selected pixel) through the image of left and right.

  Looking at this picture:

  Select a single pixel on each line in a single column-

  xxxxxx XXXXXXS

  xxxxxx XXXXXXS

  xxxxxx XXXXXXS

  Remove/cut everything except the selected pixels in only one column-

  ...... S......

  ...... S......

  ...... S......

  Now, on each line, copy single pixel selected to the left and the right of the selection, to the extent of the canvas-

  SCOTTS SCOTT

  SCOTTS SCOTT

  SCOTTS SCOTT

  Interesting challenge or Easy-Peasey?

  Thank you!

  Easy. Use the brand single pixel tool to select a line of pixels. Cmd/Ctrl-J to copy pixels into a new layer. CTRL/cmd-click on the layer icon to select these pixels. CTRL/cmd-T to turn those pixels on the width of the image.

  Need to the tab of each document (Word or PDF) being converted/combined into a single PDF file. Only have an online account. Is this possible online?

  Hi pjj,.

  When you open the Bookmarks pane (the second icon from the top in the column the leftmost in Acrobat), you will see a bookmark for each file that has been attached to create the PDF. If you have created the combined file from Acrobat.com, however, file names are changed, it won't be as easy to say what are the components. If you create the file in Acrobat, then bookmarks retain the name of the original file, so your customer will be able to tell at a glance if everything was included.

• Object Table of XMLType vs single column of XMLType Table

  What are the differences between the XMLType table object and a table with a single column of XMLType?
  
  It's
  
  CREATE TABLE XMLType xml_table;
  
  and
  
  CREATE TABLE xml_table (xml_field XMLTYPE);
  
  That should be used and when? Both may be declared to be aware of schema.

  The main difference is that an XMLType object array allows the use of the XML DB Repository to store and retrieve XML content.
  The relationship between a resource and its content is maintained by a "pointer" (REF XMLType) line in the XMLType table:

  http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb03usg.htm#ADXDB4223
  http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb03usg.htm#BJFBDEJE

  Tables based on the patterns of XMLType (including the associated nested structure) can also be created automatically through recording scheme, which is very convenient when the pattern becomes complex.
  In addition, a registred schema-compliant documents that go into the repository automatically stored in the table by default (see the annotation xdb:defaultTable).
  We can also use ACLs to control access to specific rows in a table of object XMLType.

  This is not possible with XMLType columns in a relational table.

  Glad you found the problem, but I hope that you learned a lesson that is time consuming.

  It must be remembered that we have no access to your environment. If we do not know which servers, clients, tables and users that you use.
  It may seem simple to you but doesn't realize that you provide us with two slightly different versions of the cvDetails table.

  The original post had this

  It is the same table that you started with how the column suddenly grow 50 bytes?
  This means that you did from different parts of the present in the two schemas or on two servers or you change the table between the two.

  You can't address properly when you do this. By chance it is the column that you said is now the problem.
  In SQL, the maximum length of a VARCHAR2 is 4000 bytes; no characters but bytes. Nothing more than 4000 bytes would probably be a LONG in the generic sense.

  If your error
  >
  Re: ORA-01461: can bind to a LONG value only for insert into a LONG column
  >
  means that you try to 'bind a LONG value' to a column VARCHAR2 and you can't you can 'bind a LONG value only for insert in a LONG column.

  In the proper context, the error makes sense.

  You probably have a problem with

   ps.setString(2,  objectives);
  

  because the 'objectives' has a length of more than 4000 bytes.

  Remember this answer from you?
  >
  I have read and found that there may be a problem with the driver JDBC or Characterset. Am I wrong?
  >
  The 'Hello' ASCII string is five characters and five bytes because the ASCII code is a set of characters in a single byte. The same string internally in Java is five characters but ten bytes because Java uses UTF16.

  So, if the character set of the data itself is double-byte character set then anything more than 2000 characters (4000 bytes) is a "LONG". And if your column is defined as VARCHAR2 (3950), which means bytes a doublel-byte character set which are characters of 1975.

  Then you said in a response later
  >
  I checked by the SNA Server and oracle that are both of the same but new thing I found is that oracle does not allow more than one clob column in a table. Is this true?
  >
  Somehow a hypothesis has crept it that the problem was not a driver JDBC or Charaterset, but because you can not have more than one clob column in a table.

  You could have easily tested for yourself by doing what P. Forstmann - tried to create a table and see.

  Then you completely ignored my advice
  >
  I suggest to you isolate the columns actually causing the problem.
  Change your code to insert only a few columns. When it works, add more than a few columns.
  This will then tell you which column or the columns are at the origin of the problem.
  Display the results once you determine a column that causes the error.
  >
  When you have finally made the simplest things, you have found what was causing the problem almost immediately.

  Many times you don't need 'experts' - you must use a rigorous, methodical, process step by step.

  ALWAYS, ALWAYS, ALWAYS reduce the simplest possible code example that illustrates the problem.
  If you had followed this a rule would have probably found you the problem and makes you look like the 'expert '.

  There are no shortcuts.
