Set of string into array or a table....

Hi Experts,
I am using Oracle 10G, where I need to accomplish a task...
I am getting a set of string of the sort
"|session_id~q_id~q_key~rt_id~rt_key~request_type~field_id|session_id~q_id~q_key~rt_id~rt_key~request_type~field_id| ....."
Here, as you can see every set which has 7 values is delimited by a "| (pipe)" and every value is delimited by a "~" ...
I need to insert all these into a generic table and before doing that I need to split it into individual values where every set which has 7 values will get into 7 columns in a row...
Can anyone help me out with a proper logic as to how do i go about accomplishing the same...???

Hi,
You have to use regular expression to tokenize string in fragments.
This is sample for determining CRLF in a string:
-- Tokenize rows
FOR token IN ( SELECT REGEXP_REPLACE(REGEXP_SUBSTR(XMLCDATA('custom_string') || Chr(10), '(.*' || Chr(10) || ')', 1, LEVEL ), Chr(10), '') t
FROM dual
CONNECT BY REGEXP_INSTR('custom_string'||Chr(10), '(.*'||Chr(10)||')',1, LEVEL ) > 0) LOOP
token.t --> single fragment
END LOOP;
Bear in mind that this forum is for Data Modeler product related issues, feedback etc. So before posting question search for appropriate forum. It's quite possible that you won't get answer while in wrong forum.

How can i store values from my String into Array

Hi guys
i wants to store all the values from my string into an array,,,, after converting them into intergers,,,, how i can do this becs i have a peice of code which just give me a value of a character at time,,,,charat(2)...BUT i want to the values from String to store in an Array
here is my peice of code which i m using for 1 char at time
int[] ExampleArray2 = new int[24];
String tempci = "Battle of Midway";
for(int i=0;i>=tempci.length();i++)
int ascii = tempci.charAt(i); //Get ascii value for the first character.

public class d1
     public static final void main( String args[] )
          int[] ExampleArray2 = new int[24];
          String tempci = "Battle of Midway";
          for(int i=0;i<tempci.length();i++)
               int ascii = tempci.charAt(i);
               ExampleArray2=ascii;
          for(int i=0;i<ExampleArray2.length;i++)
               System.out.println(ExampleArray2[i]);

Splitting and type casting huge string into arrays

Hello,
I'm developing an application which is supposed to read measurement files. Files contain I16 and SGL data which is type casted into string. I16 data is data from analog input and SGL is from CAN-bus data in channel form. CAN and analog data is recorded using same scan rate.
For example, if we have 6 analog channels and 2 CAN channels string will be (A represents analog and C represents CAN):
A1 A2 A3 A4 A5 A6 C1 C2 A1 A2 A3 A4 A5 A6 C1 C2 A1 A2 .... and so on
Anyway, I have problems reading this data fast enough into arrays. Most obvious solution to me was to use shift registers and split string in for loop. I created a for loop with two inner for loops. Number of scans to read from string is wired to N terminal of the outermost loop. Shift register is initialized with string read from file.
First of the inner loops reads analog input data. Number of analog channels is wired to its N terminal. It's using split string to read 2 bytes at a time and then type casts data to I16. Rest of the string is wired to shift register. When every I16 channel from scan is read, rest of the string is passed to shift register of the second for loop.
Second loop is for reading CAN channels. It's similar to first loop except data is read 4 bytes at a time and type casted to SGL. When every CAN channel from scan is read, rest of the string is passed to shift register of the outermost loop. Outputs of type cast functions are tunneled out of loops to produce 2D arrays.
This way reading about 500 KB of data can take for example tens of seconds depending on PC and number of channels. That's way too long as we want to read several megabytes at a time.
I created also an example with one inner loop and all data is type casted to I16. That is extremely fast when compared to two inner loops!
Then I also made a test with two inner loops where I replaced shift register and split string with string subset. That's also faster than two inner loops + shift register, but still not fast enough. Any improvement ideas are highly appreciated. Shift register example attached (LV 7.1)
Thanks in advance,
Jakke Palonen

OK, there is clearly room for improvement. I did some timing and my two above suggestions are already about 100x faster than yours. A few teeaks led to a version that is now over 500x faster than the original code.
A few timings on my rather slow computer (1GHz PIII Laptop) are shown on the front panel. For example with 10000 scans (~160kB data as 6+2) my new fastest version (Reshape II) takes 14 ms versus the original 7200ms! It can do 100000 scans (1.6MB data) in under 200 ms and 1000000 scans (15MB data) in under 2 seconds.
I am sure the code could be further improved. I recommend the Reshape II algoritm. It is fastest and can deal with variable channel counts. Modify as needed.
Attached is a LabVIEW 7.1 version of the benchmarking code, containing all algorithms. I have verified that all algorithms produce the same result (with the limitation that the cluster version only works for 6*I16+2*SGL data, of course). Remember that the reshape function is extremely efficient, because it does not move the data in memory. I have some ideas for further improvements, but this should get you going.

Parse string into array for comparison

Hi All,
I am trying to parse a string message into an array of numbers so I can check if my event was successful.
\FF\FE\01\FD\02\00\00\00
I know I just need to read through and discard the \, but I don't know how to do that in Labview. I just need to check if the 6th byte = 00 or not.
Thanks! I mostly need help with parsing in labview.

Assuming this is a plain ASCII string containing the letters 0..F and "\" as delimiter, you can simply used "Spreadsheet string to array" with the following settings:
Type= 1D U8 array
format= %x
delimiter= "\"
One problem is the extra delimiter at the beginning, so use array subset to skip the first element.
(EDIT: Ahh, Darin beat me with a similar solution. Mine's a little easier ).

Turning parts of a string into rows in another table

I need to extract unit codes that are stored in a string into rows in a new table as below
From:
Set_cd sequence_number rule_text
KP106A 15432 {1234,4567,8910,1567}
To:
Set_cd sequence_number unit
KP106A 15432 1234
KP106A 15432 4567
KP106A 15432 8910
KP106A 15432 1567
The strings will be of varying lengths but the layout will always be the same with the curley brackets and commas.
Any ideas please?
Thanx

String into array in oracle

Hi,
I have value in a column in oracle table as "DE","DS","KJ".
now,How can I get them into string array?
Is there any API to get this ..
Thanks
Chat

I have value in a column in oracle table as "DE","DS","KJ".
now,How can I get them into string array?Do you mean that you have a single string with quotes and commas? If so you have to parse it to extract the constituent strings. Ostermiller has a library that does this sort of thing (Google ostermiller csv) and deals with the complexity of commas and quotes within the quoted parts.
(If you know the string value consists of quoted section separated by commas, and there is no possibility of spaces getting in the way, you could split the string based on "," and then take substrings to remove the quotes.)
You should pick one thread for this and stick to it. Put a message in the other linking to the thread you want to use.

How to compare array of String with column of a table

Hi,
i have a array of string(say array is of length 1000). I want to
compare those string in array with one table column
        - whether that table column has a string
                        if yes
                                        do nothing.
                        if no
                                        then insert that string into table.
        - whether table has obsolete row i.e, the one present in table and
not in array
                        then delete that row.
How do i go about this, because i see, it is not feasible to loop
through array and search table to find new string OR loop through each
row from table to find some obsolete row
How can i accomplish this task more feasibly(without running query for
each string, for comparission)? Is there any way to find this kind of
problem. I would have been easy if i had to compare two tables(with
UNION and INTERSECT), but it is not the case.
thanks,
kath.

I'm not sure, whether I understand your problem correctly. Only two comments:
- if both arrays are sorted, all can be done running exactly once simultaneously through both arrays.
- if the column is marked as UNIQUE, all column strings will be different. I.e. you cannot insert the same string a second time.

i need help in converting a string into array of args just like command line args
i have a string s1 = 12 13 56 etc

a[0] = 12
a[1] = 13 etc
Thanks for help

U can use String tokenizer.Why prefer that over split?Yah Bobby u can use split too..
J2SE 1.4 added the split() method to simplify the task of breaking a string into substrings, or tokens.
Thanks BigDaddy.. I realized after you told.
try this too..
String str = "Your string";
String[] arr = str.split (" ");
for (int i=0; i < arr.length; i++)
System.out.println (arr);

"converting strings into integers in a array"

I'm really left scrating my head trying to figure this out.
What I have right now is this
public class NameManager
     private names[] collection; // collection of names
     private int count;
     public NameManager() // Creating an array which for now is empty
          collection = new names[1000];
          count = 0;
          String [] collection = {"boston", "Springfield", "New Haven",
                    "New York", "Albany"};
Its a namemanager for my road trip project which will be sort of like mapquest. What it does, or it's supposed to do is I have a array of names of cities, that represented as strings, in a array called, collection. What my proffeser wants me to do is turn the strings into integers, so in this elements in the array can be referenced .
It's probably so easy that I'll want to kick myself when I find out how to do it , but for whatever reason , all the information have found on the internet seems to go right over
If any body can give some idea of how to turn the string you see above into a set of intege s I would be so grateful.

turn the string into the index in the array
i.e.
boston => 0
springfield => 1
New Haven => 2
New York => 3
Albany => 4I should've mention this before but I need the names to go along with the numbers.
This is the directions from my proffesser, I know it's not the easiest to understand
but hopefully It will give you a better idea of what I'm talking about.
A name manager. This object turns strings into numbers. Every time a name is added to the name manager, it is checked to see if it has already been seen. If so, return the number previously assigned to the name. If not, increment the "number of known names" and return this number as well as remember the string for future reference. You can assume that there will be no more than 1000 names in the manager. Each name is a string.
A city. A city is a simple object: the city has a name and a number (at present).
I got most of this part done it just strings integers part that's getting me.

Table string to array

Hi,
I need to print out a specify device mac addres.
I got the mac address in table form by command prompt as attached file, but there are more than one mac address listed out.
The only mac address number i want to use, is the 4th mac address 00-04-A3-12-32-25.
May i know how to get this 00-04-A3-12-32-25 mac address from the whole table string and list it in array?
Appreciated your advice.

Here is a VI I use to get strings out of a table that has a header with seperator line ( ======== )
Feed your string into the String In. Feed the Seperator Char (in your case the =) and it will break out the table into an array that you can index to get what you want.

Is there an easy way to convert a long string into an array?

I can convert a long string into a 1-d array by parsing and using build array, but I would like to know if there is a function to make this easier.
For example:

to/       an array that is 1-d with each element having eight characters
          aaaaaaaa

          cccccccc
          dddddddd
Thank you.

Try something like this:

This is my FillRow function. Without the bold line, the everything is fine. I can create the assembly, then create the SQL function. Done. When I call select from the SQL function, it returns 10 rows as expected.
public static IEnumerable getTable(SqlString jsonStr)
ArrayList resultCollection = new ArrayList();
MyTable mt;
//mt = JsonConvert.DeserializeObject<MyTable>(jsonStr.ToString());
int c = 1;
while (c < 10)

Storing JSON string into Oracle table

Hi,
What is appropriate way to store JSON string into Oracle table?
Regards
Peter

If JSON becomes more popular, ORACLE might write data cartridge extension for JSONDB (in the same way as XMLDB).
Till then CLOB and NCLOB is your best choice, and leave the parsing in your application layer.

Set of string into array or a table....
