Match entries in an array to another array and create a new table.
I tried for a while to do what should be a simple operation. I have some of my code work exectpt for this part, which is similar to the post below.
However I try to match the first two columns in table 1 to those in table 2 and create table 3.
Please can someone help? I'm in a time crunch. Thanks in advance.
Same idea, another implementation using variants to perform the search.

I want to know if it is posibble to create a new table from another table which are ussing a stored procedure. This new table is created from another table that exists in the DB.
(in the following code the table tbl1 exist in the schema of the DB, but temp_tbl1 does not exist, it must be created by the procedure)
create or replace procedute temp is
temp_tbl1 tbl1% TYPE; the temp_tbl1 will have the same type of tbl1
create the table temp_tbl1 as (select * from tbl1);
time of the end;
Thank you very much
Yes, it is possible to create a table using a procedure.
Do everything that use dynamic SQL is
create or replace PROCEDURE Create Table as
EXECUTE IMMEDIATE ' CREATE TABLE testtable in select * from testingtable';
I want to insert data in a 2D of LabView or 1 d table in Excel and create graphics.
I used the information in the following example:
and has managed to create a new Excel file (I use Excel 2010) writes data in a 1 d table to a column in excellent by creating a while loop and using the first element of the array to write in a specific cell. I use the loop counter to write to the next cell when the loop starts again and always remove the first value, I write to the cell of the table until it is empty.
Now I also want to write a 2D - column in Excel table should be the first column of the matrix and so. Here, I can not use the loop counter directly as Excel there are only 1,2,... for the lines, but uses A, B,... to count columns. Also I do not know in advance the number of columns my 2D array will contain, thus creating a lookup table as (A means 1, 2 B, which means...) is not really an option (except there is really no other way). Is there a possibility to convert numbers into letters or somehow to "explain" to the program that this column 2 of the table means column B in Excel for example, or is it possible to insert new columns?
I figured out how to add new calculation sheets and as I also need to create a certain number of spreadsheets and I know that the standards 3 sheets are present during the creation of the file, I use the method 'Add' to create new worksheets before the worksheet 3 - I could use the same method to create new columns in Excel , but so far I have not found a method to do. Or is there a way to enter into the 2D table all at once?
So I want to create a chart (in case 1 d tables draw a bar when using 2D arrays a 3D field) to display the data. I found this example:
-> that I do not have the tool box I would do it directly using ActiveX, so I tried to make things as shown under the title "ActiveX DIY /.» NET'
I tried to load the code snippet into a new Excel file but got the error message "microsoft.office.interop.excel.dll" not found and this is why the code does not work. Which confuses me a bit as I guess when this dll is not present I can not access Excel of LabView at all, although my understanding of what I'm doing so far is limited in the calm. ;-)
Also - as far as I understand the extract - when you create a new graphic object, I should be able methods to create for her, however when I do a right click on the graphic object to a symbol of the spreadsheet ActiveX it no listed.
To explain my problems better, I added an excerpt showing my two problems: the inside of the two loops while showing how to import a table 1 d. In the outer loop I separate the columns. I know that is not currently as has all the data in the column of the Excel sheet - so I need to convert the external meter number a, B,... or find another solution.
In addition, on extract, I placed a property ActiveX spreadsheet with the Chart object - I can see that the difference to the graphics object of the example code of the last link above is the color. However I do not know what it means and how to change / fix this.
And just to make sure - I know that this path that the VI is not running as the graphical object is placed completely false – I just did, so it is included in the extract.
I would be grateful for any suggestion,
for your information in professional 2014 LabVIEW report generation toolkit is included
also good information about Excel and ActiveX
Hope that if aid, if not please let me know.
This should be relatively simple to implement.
You can create a process of pl/sql page ' on submit ' which puts the fire on the "Approve" button The code for the process would be something like
insert into permit_table(col1,col2,col3...) select
Made of total uninstall of 15.1 Firefox on another computer that is running windows vista 64, I went back and double checked everything to try and make this system was clean. Also went in the system and verified before installing Firefox 16.1 I download on Mozilla. After installation, check to see if 16.1 has been installed and saw the box showing restart to update. So I did, and still the same sign was there. Fact 3 installs since then and all the same. Checked online to issue printed out of a lot of help but still have the same problem. It is the same problem that I had with 15.1, but not with 15. Where should I go now? ideas.
You are welcome
I had a little problem.
I have a table which includes the employee vacation time. Vacation time was periodic, so I divide them into days. Now, I want to calculate the exact days. Sometimes ago weekends included I need to subtract. I have flaged everyday, I know exactly what day is a business day and that one is not. Is it possible that I have only the sum of the days without weekends?
EMPL - V_Start_D - V_End_D - Date-day - D_Name
EMPL - V_Start_D - V_End_D - Date-day - D_Name - Actual_Days
SELECT Empl ,V_Start_D ,V_End_D ,Date ,Days ,D_Name , count(*) as Actual_Days FROM vacation v JOIN datelist d ON d.day between V_Start_D and V_End_D and d.is_working_day='Y' GROUP BY Empl ,V_Start_D ,V_End_D ,Date ,Days ,D_Name
I have a server who is dead and who has hosted our VMware SQL dbase and dbase recoveries do not work.

It will work, or are there problems guests & VMs part of an another vCenter?
VM isn't registered to ESX(I) hosts, vCenter. Thus, when you 'add host' to vCenter all registered as ESXI (i) host VM are delivered with.
What is the difference between associative arrays and nested tables?
nested tables cannot be indexed by other than pls_integer and unlike nested tables table associative cananot be declared at the schema level.
is there any other difference set apart from the diff above 2?
What is the difference between associative arrays and nested tables?
Name-value pairs (associative) against a list of values (table standard/nested table).
nested tables cannot be indexed by other than pls_integer
They are not "indexed" the way in which an associative array is indexed. A standard table is referenced by the position of the cell in the table. This position is essentially the offset of the memory of the cell from the start address of the table.
Can not solve a cell in an associative array directly via a memory offset index. You place a cell reference value it by his 'name' (a search in the linked list/hash table).
The following example shows the difference between the pairs of name / value and a list of core values.
SQL> declare 2 --// associative arrays are NAME-VALUE pairs 3 type TArr1 is table of varchar2(10) index by pls_integer; 4 type TArr2 is table of varchar2(10) index by varchar2(10); 5 6 arr1 TArr1; 7 arr2 TArr2; 8 begin 9 arr1(100) := '1st entry'; 10 arr1(1) := '2nd entry'; 11 arr1(5) := '3rd entry'; 12 13 arr2('john') := 'New York'; 14 arr2('jane') := 'Paris'; 15 arr2('jack') := 'London'; 16 17 end; 18 / PL/SQL procedure successfully completed. SQL> SQL> SQL> declare 2 --// standard arrays are lists 3 type TArr3 is table of varchar2(10); 4 type TArr4 is table of number; 5 6 arr3 TArr3; 7 arr4 TArr4; 8 begin 9 arr3 := new TArr3( '1st entry', '2nd entry', '3rd entry' ); 10 11 arr4 := new TArr4( 100, 1, 5 ); 12 end; 13 / PL/SQL procedure successfully completed.

I can't deduct the answer to this question (topic/post title) of the help of LabVIEW on the functions.
Intuitively, it seems that the two representations of data are equal to the memory and so goes between the two should essentially be a no-op when the code is compiled... but is it? (assuming that the length of the array of strings/remains constant, can I go back repeatedly without performance?)
As a string of LabVIEW is a handful and any other type of data except tables aren't a handful; that implies to me that a string = U8-table-grip handle and so a string into an array of U8-could be a memory or inefficient operation since no conversion actually take place?
The reason I ask, is that when you work with for example TCP Read or read VISA, 'data' reading is always a string, but according to what you are doing, this string is often more efficiently processed/interpreted if converted to an array of U8 and I just want to know if (memory and CPU point of view) I can move freely between the chain and U8 array and return depending on what format is most appropriate to a point?
(Also, I'm at this stage fairly certain that the "array of strings of bytes" is cleaner AND more efficient than a type-cast to an array of U8 strin... but I could be wrong.)
I did some tests on this just now, and my conclusion is that it is completely in place. The local users group had a coding challenge when this became relevant to my solution.
How do I reverse Split 1-d Array of recombining the splitting table? IE I have two Boolean charts A and B, and I want them in a Boolean array: a followed by B items (NO interlacing) array elements
-You cannot convert SGL data directly on the Boolean chart that shows you the Red CoercionDot...
-always do not concatenate you the berries (despite all the comments on this subject), but instead to create a 2D array...
Hi, I just want to know the best way to transfer strings, arrays and clusters between a PC and a computer-RT (compactRIO) if I want to use them in deterministic loops:
For a string should I use a published network shared variable flow or network?
For an array of doubles should I flatten the array in a string and the string of transfer? or should I send it as a picture?
The same for clusters, should I flatten the cluster or the transfer as a cluster?
Transfers on the network are not deterministic. You ask how to use the data in a deterministic way, once it arrives on the RT system. Usually, you would create a separate loop, not critics of time to deal with network communications. The data arrives it is copied in real-time-safe structures such as RT-FIFO to put at the disposal of the evanescent loop.
I can't give you specific advice on network variables and network flows; Finally, I did this kind of transfer over TCP, until these other options were available.
I am writing a program for a measure 3-terminal of a FET.
I use 2 power supplies: for every increase of grid voltage Vg, I'm doing a drain voltage Vd Sweep and save the Id and Vd.
The attached code, you'll see a Subvi, called "I.V. 2 terminals", which returns a table of voltage Drain (1 d) and a table current Drain (1 d).
But because the output of the Subvi is in a loop (For increment Vg), the end result is a 2D array.
Whenever a table is leaving a loop it acquires a dimension.
So ultimately I don't know what are the clues. How can I prevent the table to have a dimension of their out of the loop For?
I would like to see the output of the Subvi to go straight out of the loop, intact.
I have attached the Subvi as well, but I don't think that you will need.
Thank you! I'm still very new to LabVIEW and I really appreciate your help.
You can disable autoindexing on any tunnel by clicking right, with evidence that cause you only get data from the last iteration. Is what you want?
I have a problem with the update of the elements of an array and use these items again. Well, I have the clearer idea. I have a one-dimensional array of double. Now I'm just comparing two adjacent elements. If the difference is greater than a threshold, I need to update all other elements (for example, add 100 with all the remaining items). Then repeat the whole things until all elements are compared. I tried the following. But I'm not sure how to use the updated table "Method 2" instead of "method 1" in the following loop. ' " In Place element Structure"has not helped.
I know it's pretty simple in C++, where we can use the reference to the table. I'm new in labview and don't know how to do it here in labview.
Looking for your help.
Have you tried just using the tool 'unwrap the phase"?
How to make a 1 d table and create a pointer to the first position to put an image in? I thought that's what I did (see picture) but continue to get an error of 1097, probably due to the incorrect memory allocation. I have the size of the image in bytes and a string, will call a dll and am pretty sure that is not what is causing me problems. However, the pData is supposed to be a pointer to the first element of a 1 d table which is the width in pixels * height. I read on the website of LV table of the image I did look like a 2D array, but is actually a 1 d array and that the pixel pointer points to the first element of the array. Is it not the case? Thank you.

One of the major downfalls of Aperture is that it shows you where are your pictures. They always favored it as a feature (even as a ' new paradigm'), but it's not so wonderful when you need to do something about Apple never intended. Then, it sounds really like it led to you not knowing where your files or files that correspond to which elements of the UI opening. I suggest that you need to nail for yourself - images from Aperture to right click and choose Show in Finder, until you know where everything is.
Otherwise, make sure you have plenty of available disk space, stop asking questions and just see what happens when you run plugin import LR with the options I suggested. It won't damage the opening.
