• Game max fixed the number of rows in a table

  Hi all
  
  I created a table that should contain only one line and avoid the possibility to add other lines to it, I used the following:
  

  CREATE TABLE <table_name> (
      <field_1> <field_type> unique,
      ...
      <field_2> <field_type>
      CONSTRAINT <field_1_ck> CHECK (<field_1> = <value>) 
  );

  It works, but it seems a bit heavy for me... Is there a better way to define a fixed/maximum number of rows in a table?
  
  See you soon,.

• How to set Max number of rows in a table?

  Hello
  I'm working on a SCADA interface. In this application, there are different tables with vertical scroll bar.
  I prefer to make it visible only initialized lines (I've initialized 40 empty rows in a table with an array of strings). Since the window contains all 40 lines, but only 20 rows, I put the number of lines in the "table properties window" at 20; So I added a vertical scroll bar.

  Now, when a user, do scroll the scroll bar, it can check not only the initializated 40 lines, but any number of lines.
  There is a way to view only a limited number of lines?

  Thanks in advance!

  Thanks for the info, looks like a nice tool will ;) try
  but I really want (my problem) in pl/sql

  Take a quick re-read my post above.

  PL/SQL is a process running on the database server. This process cannot interact with the client computer. He can't ask for user input, and it cannot display the output to the client. Client interface tools can only do. You are eager to get feedback from a user, if you need an interface tool to do. SQL * Plus can interface and application of entry, but only as variable substition, and it does not really provide a programming construct that allows you to run a program in a loop to do. Do this using SQL * Plus you must pair it with shell/dos scripting languages, but more ideally you should use an interface appropriate as Apex.

  I was wondering if it all works in pl/sql to release cached data (as fflush (stdin) in c ++)

  PL/SQL does not a customer entry, so there is no sense to have something to release the cached data. You pass the values of PL/SQL code using procedures or functions with parameters.

• Count the number of rows in a table (s)

  Hi all

  I have a TKT_PRIORITY_LK table that I want to count the number of rows returned by a priority level... say Low, Medium, High, critical. I want to be able to count how many of each created are they, instead returning ID instead, if making any sense... Can you please help with this.

  Example; Select count (*) in TKT_PRIORITY_LK

  PRIORITY group

  Kind regards

  Sandrine

  Try this

  Select a.PRIORITY, count (*) from TKT_PRIORITY_LK a, TKT_TICKET_MAIN b

  where a.id = b.PRIORITY_ID

• How to truncate 1000 rows from a table of 7000 lines?

  Hello

  Please give me a quick answer to truncate the 1000 rows from a table of 7000 lines... I don't want to truncate the entire table

  Thank you all for the valuable support,

  My activity is still ongoing... Somehow my client was not specific about what lines are deleted. It has no date column in the table to delete records by date...

  The table contains information about the error logs, so he wanted to keep a few lines and remove the rest... and then copy the table to another database.

  So right now using this query:

  SQL > delete (select * from ) where rownum<>;

  Once again thank you to all...

• How to create a large group of tables of all different lengths

  Hi all

  I want to create a 2D array that has two coloums and X number of rows (possibly in the hundreds). The first coloum must have a calculated average for this line. The second coloum should have a gap with the average assosiated. I struggle to get to this point. I know how to aqquire the set of values that should be considered for each mean and STD and I also know how to calculate the average and std.

  A loop will tell me what is the value of tag and which line in X put in. I want to be able to have the X number of tables each representing a row with values before calculating the avg and std. Each table would be of a different duration.

  I don't know how tag on the unique values of the loop to the appropriate line to create the Group of X tables.

  The only way I can think to do is the initialization of a 2D table large exessvly and replacing the first available null in the row with the value form the loop. Then only, I wouldn't consider zeros when I do the final 2D picture. What I don't love about it, is that it would be exesive and it is possible that there wouldn't be enough zeros for all the values that I wanted to consider in a specific line.

  I do not want to calculate averages and STDS for every line, every time I have add a value from the loop either. That would allow me to pass the table groups but would also slow the program. Can someone give me some advice on how to run this? Thank you in advance!

  Use a cluster.  In your case, the cluster contains a data table and two digital inputs for the mean and std dev.  Look at the joint.  I created a control of Type Def the type of data I think you want.  In vi, you can see how to use the cluster to write your data.  For multiple series of data, you would have a picture of this cluster.  Each could have an array of different lengths and his averages dev partners and STDS.

• How to select each row in a table where there is no user input?

  My order is: DUMMY_BLK. It has field: NWTFR.
