  Of course, it is possible.  According to what the text file looks like to, you can create an external table that treats the text file as if it were a table.  Otherwise, you can always read the file in PL/SQL, using the utl_file package and INSERT of PL/SQL commands.

  You have problems whatever you wantt?  If so, your zip code and explain what the problem is.

  Whenever you have any questions, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the exact results you want from these data, so that people who want to help you can recreate the problem and test their ideas.  In this case, also post a small sample of the text involved file.

  If you ask about a DML operation, such as INSERT, then INSERT statements, you post should show what looks like the tables before the DML, and the results will be the content of the table changed after the DML.

  Explain, using specific examples, how you get these results from these data.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

• Is it possible to display a pop-up for 1 time when the recordset is not null

  I heard that it is difficult to pass the PHP variables in javascript, as I can't possibly write javascript in php tags.

  The pseudo-code is like this:

  If the recordset of the query is not null, then popup a window, to get the results of the recordset object.

  The code looks something like this, but I know it is not possible to put js(in bold) in the php. The idea is sort of like this:

  <? PHP

  ......

  $today = date("Y-m-d"); today's date

  @mysql_select_db ($database_myconnection2, $myconnection2);

  $query_Recordset5 = sprintf ("" SELECT * FROM temp WHERE the dev_expdate < %s ", GetSQLValueString ($today,"text")");

  $Recordset5 = mysql_query ($query_Recordset5, $myconnection2) or die (mysql_error ());

  $row_Recordset5 = mysql_fetch_assoc ($Recordset5);

  $totalRows_Recordset5 = mysql_num_rows ($Recordset5);

  
  

  < script type = "text/javascript" >

  If ($row_Recordset5! = Null)

  {window.open ();

• My printer is connected to two computers. I find that the second computer does not print unless the first computer is also on. Can I get every computer to print without the two be on?

  the printer has been first on windows 7 and second on windows xp, because that's the way I was told iy had to be done. But I thought that each computer can print separeately withou t windows 7 being on.

  Hello

  1. How is the printer connected? This printer is on a network?
  2. this configuration was already working before?

  You must configure a print server. If your printer is a network printer, you can connect it to a router, and all computers connected to this router can use the printer individually. If the printer is not a network printer, you can buy the equipment to turn it into one.

  See the articles below for more information:

• If you have two hard drives, can you wipe the second and just use it as a storage device?

  If you have two HARD drives in a PC Windows 7, can you remove everything (including the System 32, Windows users, literally everything) in the second and still use his computer? All my programs on the first HDD would remain on my PC, but all the files of the second being scratched? I'm running out of space on my first HARD drive and need to know if I can keep the second as storage just pure.

  Thank you.

  Hey Elliot,

  Thanks for posting your query in the Microsoft Community Forums.

  According to the description, it seems that you want to delete all the data on the secondary hard drive without affecting the first hard drive operating system files.

  I'll be happy to help you with this.

  If the operating system (Windows 7) is installed on the first hard drive, it has nothing to do with the second hard disk. You can go ahead and delete all data without hesitation.

  Note: Make sure that you remove the data from the hard drive where Windows 7 is installed.

  If you want to reduce the number of unnecessary files on your hard disk to free up disk space and help your computer run faster, use disk cleanup.

  For more information, see the link.

  If you have any other questions, feel free to let us know. We will be happy to help you.

• Concatenate two columns and store it in the existing column

  Hi all

  I created a form based interactive report and need help on that. In the report, I want to display a column with label the CANDIDATE's FULL NAME by concatenating the existing columns in the same table.

  Am mentioning the details and the following questions:

  Table name: CANDIDATE_DETAILS

  Column 1: CANDIDATE_FNAME (first name) Data Type: CHAR (50)

  Column 2: CANDIDATE_LNAME (family name) the data type: CHAR (50)

  Column 3: CANDIDATE_FULLNAME (full name) Data Type: CHAR (100)

  If in the case of column 3 that is, CANDIDATE_FULLNAME is not created in the database, I could have written in query to create one using the concatenation of columns 1 and 2 of the column

  ALTER TABLE CANDIDATE_DETAILS ADD CANDIDATE_FULLNAME TANK (100 CHAR)

  AS (CANDIDATE_FNAME |) ' ' || ( CANDIDATE_LNAME)

  Since then, I have already created CANDIDATE_FULLNAME column, I just change or simply store the concatenation of Column1 and Column2. I tried to use under request, but his does not work:

  ALTER TABLE CANDIDATE_DETAILS

  CHANGE CANDIDATE_FULLNAME ACE (CANDIDATE_FNAME |) ' ' || CANDIDATE_LNAME)

  Also I'm checking the code under SQL Workshop-> SQL commands by entering the query below and his works fine.

  Select CANDIDATE_FNAME. ' ' || CANDIDATE_LNAME

  of 'CANDIDATE_DETAILS '.

  but do not know where to enter this code in "The Page Creator" that without creating an additional column in the database my needs can be met.

  Please let me know if you need more information and really appreciate any assistance.

  Thank you

  Verhasselt

  Hello

  If the requirement is to display the columns and their contents concatenated in a third, you can try this:

  1. create a new column in the report by adding code to the selection of the report:

  Select CANDIDATE_FNAME, CANDIDATE_LNAME, "'"CANDIDATE_FULLNAME"'CANDIDATE_DETAILS'"

  2. in the page editor, select the "CANDIDATE_FULLNAME" column and his correspondents "formatting of column" > "HTML Expression" describe what you like:

  #CANDIDATE_FNAME # #CANDIDATE_LNAME #.

• Column Salary to come in the form $ does not time?

  Trying to get this works, but can't. Help, please. You will need to get the column Salary to come in the form $ instead of the time. Whenever it is multiplied by 12, it ends by multiplying by time and not by $12. So I'll take 48 h 0 m instead of $48. There are some pictures of what I am trying to accomplish. There's a picture of what is happening and another pic of my formula before you enter the time in time and get the product duration under treatment. Help, please. Thank you

  

  

  E SALVATION '

  You multiply at a range of a number. The result is lasting. That makes sense, if you do 15 minutes (duration) of exercise every day for five days (number) you have made 1.25 hours (duration) of exercise.

  For a numeric result, you need to multiply a number (hours) by a number of $ / hour. Your friend here is DUR2HOURS, which converts a duration in a number representing the number of hours:

• Choose the value is not null in my database using report 6i

  Hello world
  I have 2 fields in my database and I want to put in my report that the data that is not empty.
  I have the following code example, but I don't know where to put in my report and how to use it:
  Can someone help me please?

  SELECT column1
        ,column2
        ,DECODE (GRADE_Num,NULL, GRADE_Letter,GRADE_NUM) AS grade
  FROM ....

  Hello..

  Depends on what you want to do...
  What is your main query, your column of formulas or perhaps within a function, or a procedure... .so depends on your needs place you only
  And the decode line will always search results if this value is null. .because you tell if grade_num is null then show the note by letter... otherwise (way grade_num is not null), you will see the grade_num...
  This can be achieved using the NVL function also...
  instead of decoding you could write NVL (grade_name, grade_letter)...
  NVL function works as follows: If the first argument is null then subititute as the second argument.

  If your goal is to extract the lines where a certain column is not NULL only, you can then you can also say something like that...

  SELECT column1, Column2
  From table_name
  where (Column1 is not null) AND (column2 is not null);

• How to effectively check if a field in the form is not null

  Hello

  I'm guessing there's a way to programmatically check if a field has been entered during the loading of the form.  A sort of loop should do the trick...

  I tried to use the following code (from dohanlon for another purpose) which must run through all fields in the form, but I can't plug it in an if/else statement or even check for any value non-zero.

  xfa.resolveNodes (' form1... #field [*] "" ');

  Conceptually, here is how I like to do:

  If (xfa.resolveNodes ("form1... #field [*------]".rawValue!)) = null) {}

  Do it

  }

  Basically, I'm just checking if any field is not null, then I can "do something".  I know that I can't use it to check .rawValue but I can't think of anything.

  I'd appreciate any help (as always).

  
  

  Hello

  I prefer loops, because you can build in a little management as well as errors.

  See an example here: http://assure.ly/H1ksGR.

• Error running columns must be updated in the error table

  Hi all
  
  I deliver, in my process when execution time if I got an error, that it would be updaed in my error log table, is there any special function is there for that?

  Hello

  For any error that occurs in your trapping interface use the package step.

  Go to step 1 to step 2 by KO trail

  in step 2, you can use a variable with a refresh of query ' select SUBSTR)< %="odiRef.getPrevStepLog" ("message")="" %="" >,="" 1,="" 4000)="" du="" double="" '="" faire="" passer="" votre="" message="" d’erreur...="" de="" cette="" façon,="" vous="" pouvez="" gérer="" vos="">
  Also, as mentioned in a previous post, you can easily change your variable as refresh query

  *'select SUBSTR (< %="odiRef.getPrevStepLog" ("message")="" %="" >,="" 1,="" 3000)="" || »=""><->' |)< %="odiRef.getPrevStepLog" (« step_name »)="" %="" >="" du="" double="" '="" *="" d’inscrire="" le="" nom="" de="" l’étape="" afin="" que="" vous="" sachiez="" où="" cette="" erreur="" s’est="">
  Now, you can use this variable to insert this value into a table of error log using a procedure of ODI step (do the next step).

  Solve your problem?
