  really, I try to write down, but I had a lot of values for each ELITE and I need only the first, that
  SELECT * from me_result
  WHERE (ELITE, REGEXP_COUNT (combined_str,' ;')))) IN
  (SELECT ELITE, MAX (REGEXP_COUNT (combined_str,' ;'))))) ME_RESULT ELITE GROUP);

• How to find the value max and min for each column in a table 2d?

  How to find the value max and min for each column in a table 2d?

  For example, in the table max/min for the first three columns would be 45/23, 14/10, 80/67.

  Thank you

  Chuck,

  With color on your bars, you should have enough experience to understand this.

  You're a loop in the table already.  Now you just need a function like table Max and min. loop.  And you may need to transpose the table 2D.

• I have copy of old tbird and seamonkey e-mail files with the files and emails for each. I need to add to new tbird install. can not find a way to do it. Help

  I have copy of old tbird and seamonkey e-mail files with the files and emails for each. I need to add to new tbird install. can not find a way to do it. HELP PLEASE. previous e-mail files are under mail then mail.earthlink* .net and each of the five mail .net is an email address I have. I can't find a way to identify each file by email to the specific email address (IE mail.my E-mail name.net) so I can copy the files and emails from the past to the email addresses now under tbird. previous installed e-mail identities may not be the current configuration of e-mail files in tbird. I think that I must be sure that mail.name.net matches the previous mail.name.net to be able to copy and paste the old to the new. is there a way to find the file name correct the old email and correspond to the new? all my emails very important information are mostly in the old mail electronic id and must be available in the identification of email again (but same) how can I do this?

  I'm with you.

  > How can I writer this number in the code? Is it 0026 or 26?

  The code expects milliseconds, then 26 seconds would be written as
  this:

  26000

  If he said 01:22 (one minute and 22 seconds), you must write it like this:

  82000

  ... which is 60 seconds for now, 22 seconds
  side, then multiplied by 1,000 to get milliseconds.

• read the max and min of each column value

  Dear qudoe

  I'm doing a program in labview that challenge me to fight with a time.

  Here, I enclose my labview code in which I have a data file, which includes 500 columns that I need to find the values min and max of each column.

  I tried my best, but it takes 30 seconds to find the min and max value of each column.

  I want to do this in less than a second.

  so can anyone suggest me any necessary correction that can stimulate my program.

  You don't have to open and close the file in a loop all the time and also you don't really need some time for this. Check the related code.

  

  Of course, you can still optimize it for best performance, I just did a quick project to show how simple it is.
