String table in full
Sorry to ask a such simple question here.
I get a string of numbers such as 11.812. I want to convert this string 11.812 in full. Currently, I tried to use a decimal string to the number, but all I get is 11. I need clarification 11.812.
Please help thanks! : womanhappy:
Try using the Fract/Exp to string number function.

The input string is abc = 4, def = 5. I would like to string array of production with abc and def elements. delete the number including the equal sign... For this I used string table spread sheet and the format used % [^ = d *]. Any suggestions?
Hi nik35324,
You are so close to the result.
Just delete would be "of the format string % [^ = d *] and use % [^ = *] "
This will solve your problem.

More on my table of full scan question...
Ok. Apology. start one new thread, like other a receipt very complicated... If anyone can help Id be very grateful, because this results in a significant performance problem...
XE 11.2
Re this query:
Select ENTITY_BUDGET_CAT,
Sum (actual) real by
de)
Select Br ENTITY_BUDGET_CAT_ID as ENTITY_BUDGET_CAT,
sum (br. BRI_CREDIT) under the real name
from: br bri_recon
Group of BR. ENTITY_BUDGET_CAT_ID
)
where ENTITY_BUDGET_CAT = (SELECT "EBC". (' ' ID ' FROM 'ENTITY_BUDGET_CAT' "EBC" WHERE 'ENTITY_ID' = 55)
ENTITY_BUDGET_CAT group
The query results in a table full of BRI_RECON scan, even if there is an index on BR. ENTITY_BUDGET_CAT_ID... If I put the where conditition on the inner circle question it works fine.
The void, select retrieve entity_budget_cat on where clause returns a single value.
If I replace the subselect statement to get the entity_budget_cat with a literal value, it uses the index on ENTITY_BUDGET_CAT and is much faster with a much lower cost.
If I remove the sum (actual) external and just retrieve the value and no group, it also uses a sweep of indexes on the inner query on BRI_RECON.
I need instruction in this format because its share actually well expand with unions comprising the sum of 4 tables, then later adds the value of the outer query to retrieve a single value by group of... The docs say that the filter must be passed to any SQL internally, but everything Ive tried to change the query, but leave the internal SQL without a where clause clause and apply it on the outer query. (as I would a view) translates into a full table scan.
Here is a simple example of the view I have as an example of how the larger view needs to look for tables of the amount and return a single sum by group...
Create union_sum_view like)
Select sum (a) as a 'b' b
de)
Select nvl (sum (2), 0) as a 'b' of the double
Union of all the
Select nvl (sum (2), 0) as a 'b' of the double
)
Group by 'b '.
)
Select * from union_sum_view where b = (select "b" double)
Ive tried to put a hint about it, and it doesn't seem to make a difference...
Ive looked full statistics on the diagram too...
So my question is: what is causing the full table scan (which is clearly much less effective). And given that I need to build a view in this way, how can I change to use an index in this format, or what I do to make it work... All variants and the traces are below...

Because the query runs faster when you use literal is because Oracle merges internal queries and views, so that it looks to below.
Select Br ENTITY_BUDGET_CAT_ID as ENTITY_BUDGET_CAT
sum (br. BRI_CREDIT) under the real name
from: br bri_recon
where br. ENTITY_BUDGET_CAT_ID =
Group of BR. ENTITY_BUDGET_CAT_ID
However when a subquery is used, as in the column ENTITY_BUDGET_CAT - the subquery must be run before the outer query can send more data, so that the outer query to only return results that match records based on the subquery.

Maybe you should re - write the query as follows so that the optimizer would get the opportunity to merge the view and give you better performance...

Path to XML index table is full table scan
Hi all
I have a version of oracle 11.2.0.4.6 database
Try to implement partitioning on XML indexes.
Creates a table and index partitioned by time stamp as below.
Whenever I'm trying to find the path table makes a full table scan.
I have applied the fix as indicated ( Doc ID 13522189.8 ).
So the recovery is quite slow and partition pruning does not not on XML indexes.
Wondering if anyone has experienced the same problem?

I have a drop-down list box and the value comes from a database, what I want to do is I want to change the value of the selected box based on the existing value in the database drop-down list. for example, A, B, C D I strings in the drop-down list box, and then in my database, I have a field with the string C, I want to change the C to A. I can't enter the value of C in a string format, but I don't know how to be the first position of the drop-down list box in so the order of channels combo box will be C, A, B, d., the value of C
Thank you
Then just write a new array of strings, with the elements of the new agenda, to the "[] strings" - property.
Either you must code something that allows you to create an array of strings with the elements in the order that you want them to be. If there is a reorganization only, you could do something like:
-Get the array of strings [] from the drop-down list using a property node box.
-Find the position of the element you want to place first and use "delete from table", which returns the new array and the element removed.
-Build a new table 1 d of the deleted item and table remaining. Move to the second combobox Strings [] property of a node property.

Problem on Converersion in string table
Hello world
I have an array of type "string", which all elmenmts are the same: "9.91E37."
I'm going to do an array of length 64 (64 items) of the '9.91E37' value with a comma between each one (except the first and the last of them).
The result is supposed to be like this: 9.91E37, 9.91E37,..., 9.91E37
Is it possible to do it quickly? I don't really have to use this table, but just a chain with 64 elments, it must have taken some methods to do in labview other than 64 of them by typing in a constant string.
Thank you very much
+ Kunsheng Chen
Try "Table chain spreadsheet" with a comma as a delimiter.
(To make the array of strings, you can use 'initialize array' with the string desired as element and length = 64)

Hello
Im trying to convert a 'table 2D channels' to a 'string '. I got a simple/effective way to do this?
My 2D array is user input in a list/table field. The output must be a string data type, which can be read using the indicator drop-down list box or a string indicator...
In other words, the entry of a table should be converted into a data type similar to an entry in a zone of control of chain... I went through some of the forums and discussions, I quite couldn't understand exactly how the conversion is made...
Thank you

I agree with crows that is not not clear at all what you want. To convert an array of strings into a single string, simply use the string concatenation.
If the string must have separators, use "table to a spreadsheet string.

Hi all...
I'm doing a program to read data from the buffer of 2182A (nanovoltmeter) using VISA (SCPI Programming). Now, I can get the data in the buffer, but it is in the form of a string. Can you tell me how I can convert it to a (separate for each reading) table (screenshot of my test data is attached)...
There is also a small scan only steps 10 and 11. Insofar, the scan may be more than 100 steps so please keep this in mind so...
Found my solution... Post here for everyone perhaps it may be useful for someone

How to use a control to change the part of array of strings? Insert in the string table?
Please see the attached illustration. The paintings of two strings which I'm trying to maniuplate are surrounded and the value is (bad) highlighted in yellow.
It is a part of a Subvi on a comprehensive program where I address three different cDAQ chassis, which are named cDAQ9188-TBL01-Remote, remote-TBL02-cDAQ9188, cDAQ9188-TBL03-distance max.
I intend to have three separate executables running simultaneously but independently, each dedicated to a different frame. Rather than manually changing the only integer and create a new Create_Task 002 and 003. VI for each of them, I would have the whole selectable by the user. Simple 1, 2, or 3 before starting the program and inserted it in the correct place (cDAQ9188-TBL0X-remote X of the location).
I managed to insert characters in the simple strings, but nothing seems to work with table 1 d of string. Is there a chance for this or should I be building my channels tables quite differently?
You'll just have to change the 1,2,3,... in your tables of strings with the appropriate format specifier, then add digital control and two knots in String Format and Bob is your uncle.

Spreadsheet string table / why data medium becomes zero
Hello
I converted an array of 3 x 2 to 2 x 3 table with table 2D to transpose, then I used "table to a spreadsheet string" vi to convert my table from 2 x 3 to a string. The string format is %f. The table consists of numbers and the text as:
frequency capacitance resistance
100 10 100When I try to write data to the file text the number in the Middle becomes 0. I used probes for debugging. I discovered that the problem is in the output of the 'picture to a worksheet string' vi. The input data (which are a 2D table) are ok, but out (which is a string), the average data are zero! I can not find the reason.
Thanks in advance for your help
The problem lies in the scale of your value. Primary parameter is 14.5, which rounds to zero because it is rounded to 6 decimal places and pico is too small. Use %g instead of %f for your format code.
I do not understand why you generate values at the ends of the empty table. A lot of this manipulation of cluster and table seems unnecessary.
I removed the while loop and the agilent Subvi is so I could run this. But basically your code can be disassembled for this.
PS: because you have attached the code, we could zoom in and see that the problem was with the size of your data, that we couldn't see on the initial partial screenshot of the code.

Hi all
I use the string of worksheet to the array function, and basically, my problem is the following:
My entries are in scientific notation, so I use this in the string format. The data are broken down with a «,» What I get is just the round argument.
As I just realized I didn t make me clear I ve attached a picture of the problem. Note that the 4 probe corresponds to the entry that I want to build the table, and probe 5 is out. I have just the 9 but what happens with the rest of the number?
PD: I ve tried many formats, but none of them seems to work.
Thanks for your help
Your system is configured to use a comma (,) as the decimal point? Try using ' %.; %^.3E' for your format. The "%;" tells the scan using the period as the decimal point.

Tenaris the sorted string table section and put it at the beginning
Hi all
I have an array of sorted strings (see ataached), which contain strings, numeric as T1 - T2, T1-1... T8-1 T8-2... T32-1. I want to do is to select the completeT8 and T9 parts and put it at the beginning of the table keeping remaining table sorted. Is it possible to do so. I try to match and replace without becoming confused in its use.
Thanks for the help.
Ankit G
"Strings of tooth (out)" contains your original sorted table "tooth Strings (en)" with T8 and T9 at the beginning. There is no deleted items or repeated. The code is attached.
