• Select the first 20 days of the month for a given date

  Hi gurus,
  
  Please let me know to select the first 20 dates for a date supplied by using a parameter.
  
  For ex -.
  
  Suppose I provided a date by using a parameter - January 13, 2012
  
  The query should return me - 01-Jan-2012, January 2, 2012... January 20, 2012
  
  or if I get home on 23 March 2012
  
  The query should return me - 01-Mar-2012, March 2, 2012... 20 March 2012
  
  Thanks in advance.

  Hello

  Here's one way:

  VARIABLE  target_date     VARCHAR2 (11)
  EXEC     :target_date := '13-Jan-2012';
  
  SELECT      TO_DATE ( SUBSTR (:target_date, 4)
              , 'Mon-YYYY'
             ) + LEVEL - 1     AS a_date
  FROM     dual
  CONNECT BY     LEVEL     <= 20
  ;
  

  Note that this does not take account the part of: target_date that represents the day of the month. When you use TO_DATE without giving a date of the month, it defaults to the 1st of the month.

• It is possible to select more than one layer by selecting the first and the last layers?

  I frequently get Illustrator files which are individual objects such as the paths on separate layers that can be grouped together to make the shorter layers. I find that I have to change click on each individual layer to select it to finally bring together them. Sometimes, I have 25 or so layers that I need to select. Is there a way to select the first and the last layer in the layers palette and have Illustrator select all the layers in the meantime?

  Don't know about the selection of layers of first/last, but to select several consecutive layers in the layers palette...

  Option-click on (Mac) on a layer to select it and, with the option always pressed key, drag to the bottom of the list - DO NOT slip on as logical target icons you like.  When you drag to the bottom of the list of layers, the icons of the target will become selected.

  Shift + Option-click allows you to ignore the layers and continue to select consecutive additional layers on the bottom of the palette.

  Note: Drag slowly or some layers would not choose.

  Strange, I know.  It took me years to come across this.

• How can I select the first date (at least) and the corresponding date of two different tables source?

  I have 2 tables, INVOICE and INVOICE_REFNUM similar to below. I'm writing a query that withdrawing the first date (less) for a single record remaining the two tables. Each table records the receipt of invoices, but according to the source of the received invoice some may reside in INVOICE_REFNUM and others the INVOICE table. I also use DECODE on the topic of INVOICE_SOURCE, when the date less is taken from the INVOICE table that contains that field, so if the date is in the field INVOICE_REFNUM DECODE is not necessary. Example:

  INVOICE (table)

  INVOICE_GID INVOICE_SOURCE INSERT_DATE

  ABC. AVRT123 I HAVE 11/03/2012-15:49:32

  ABC. CNWY234 G 12/03/2012 14:07:30

  ABC. UPGF678 M 15/03/2012 20:21:54

  INVOICE_REFNUM (table)

  INVOICE_GID INVOICE_REFNUM_QUAL INVOICE_REFNUM_VALUE INSERT_DATE

  ABC. AVRT123 SOURCE ACS 11/03/2012 14:49:32

  ABC. CNWY234 SOURCE CSA 12/03/2012 13:07:30

  ABC. UPGF678 SOURCE ACS 15/03/2012 21:21:54

  My decode statement is: DECODE ("INVOICE_SOURCE, 'I', 'IDE', 'G', ' Auto-Pay", ', 'Manual')

  If I were to write a query on these two tables, the output will resemble the following:

  INVOICE_GID INVOICE_SOURCE INSERT_DATE

  ABC. AVRT123 ACS 11/03/2012 14:49:32

  ABC. CNWY234 ACS 12/03/2012 13:07:30

  ABC. UPGF678 Manual 15/03/2012 20:21:54

  I worked on it for 2 days, and I was able to pull a date by using the following SQL code, but cannot determine how to extract the corresponding source:

  SELECT THE LEAST (GLOGOWNER. INVOICE_REFNUM. INSERT_DATE, GLOGOWNER. THE INVOICE. INSERT_DATE) AS 'DATE OF THE INVOICE.

  GLOGOWNER. THE INVOICE. INVOICE_GID,

  DECODE (GLOGOWNER. THE INVOICE. INVOICE_SOURCE, 'I', 'IDE', 'G', 'Auto-Pay', ', 'Manual').

  GLOGOWNER. INVOICE_REFNUM. INVOICE_REFNUM_VALUE

  OF GLOGOWNER. INVOICE

  LEFT JOIN GLOGOWNER. INVOICE_REFNUM

  ON GLOGOWNER. THE INVOICE. INVOICE_GID = GLOGOWNER. INVOICE_REFNUM. INVOICE_GID

  WHERE GLOGOWNER. INVOICE_REFNUM. INVOICE_REFNUM_VALUE = "ACS."

  AND GLOGOWNER. INVOICE_REFNUM. INVOICE_REFNUM_QUAL_GID = 'SOURCE '.

  AND GLOGOWNER. THE INVOICE. INVOICE_TYPE = 'I '.

  ORDER OF GLOGOWNER. THE INVOICE. INVOICE_GID

  Any help is greatly appreciated!

  Hello

  Is that what you want?

  SELECT i.invoice_gid

  CASE

  WHEN ir.insert_date<= i.insert_date ="" then ="">

  WHEN i.invoice_souce = 'I' and THEN 'EDI '.

  WHEN i.invoice_souce = 'G' THEN 'debit '.

  WHEN i.invoice_souce = am' THEN 'manual '.

  END AS invoice_source

  , The LEAST (i.insert_date, ir.insert_date) AS insert_date

  I have the Bill OF

  JOIN invoice_refnum ON i.invoice_gid = ir.invoice_gid ir

  WHERE ir.invoice_refnum_value = 'ACS '.

  AND ir.invoice_refnum_qual_gid = 'SOURCE '.

  AND i.invoice_type = 'I '.

  ORDER BY i.invoice_gid

  ;

  There is no reason to do an outer join if you only want the lines with specific values anyway.

  What happens if the 2 tables have exactly the same invoice_date?  The query above takes the invoice_source of invoice_refnum in this case, but that can easily be changed.

  Or the other of the insert_dates can be NULL?

  I hope that answers your question.

  Otherwise, thank you post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also after the results you want from these data (otherwise what you have already posted).

  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).

  Depending on your needs, maybe you want to Request Top - N, something like this:

  ROW_NUMBER () OVER (PARTITION BY d_rank

  SELECT d_rank, product_id, product_desc, category, price, income, cost

  OF got_r_num

  WHERE r_num = 1

  ;

  I hope that answers your question.

  If this isn't the case, please post a small example of data (CREATE TABLE and INSERT statements) and the results desired from these data.  (I know you said this is a game of results from a query, and not an array, but the solution is the same as the entry is a single table, or a query, perhaps involvoing several tables.)

• How to select the first item in an array in a loop FOR

  Hello.

  I use Labview 8.5

  In my application, I have a loop 'for' where I read some values from a device. (strings and digital)

  As you know Labview 'stores' values up to what the loop 'for' is completed, and then they come out in a table.

  Ok.

  I want to just use the first element for strings and digital and then do something with it, like to compare (for digital)

  For strings, I used successfully 'Split 1 D Array' and choose 'everything first subarray'. Good.

  Now for digital that works too, but the result is an element, array type too. I need to be digital (decimal) is not no table type, because I need to compare (greater than 0). Then use a case...

  So, table of an element in a digital decimal? Or the table at the first decimal element. How?

  I tried also with the subset of the table. Even think. Labview won't let me compare a table 1 d with 0. It makes sense, but how to convert, to have the first decimal element?

  Try to use the 'Index Array' function. If you do not connect to the terminal of the index value, it will return the first elelemnt in the table. If wire you an index, it will return the value specified.

• Close the startpoint and endpoint without selecting the first

  Hi guys,.

  I'm working on an image of polygon which means I have created hundreds and hundreds of small triangles with the path tool.

  Now, I have wondered if it is possible to create two lines of the triangle in hand and close the last third line of triangles in shortcut.

  There may be a shortcut (or almost) to connect the beginning and the end of a path? I know I can do it by clicking on cmd + J, but I first select the points which is more work than simply connecting them to the hand. It would be perfect if there's any way to close it without selecting it first, so that I can do an 'action' out of it with a shortcut!

  Any ideas?
