Looping through result set

Hello, I am experience a heapdump while looping through a result set from a query I amr unning.
Our system creates an instance of a transfer object representing one row in the result set for each row as it loops through. The result set brings back 36000 rows, so it is creating 36000 objects. As a result, a heapdump is occurring. What can be done to fix this error?

even if it holds 360000 rows,
I still think [zadok] idea is a great idea.
you can get, for example first 1000 rows, cacluate it save result, and then get the next 1000 rows, is it make sense?
if you still want to get it by one time, extend your vm mem, normal setting is 64M(I am not sure)

Loop through result set and delete row

so here is what I need -
I have a query that pulls rows from the Database through a stored procedure.(these are properties in an area)
Before I start looping through the query, I need to check the distance between my current location and the property. If it less than 5 miles, only then should I display that property. The distance in miles will be chosen while submitting the search form.
So is there a way to delete rows from the result set based on the criteria? Or
Is there a better way to accomplish this? I am using the the google api to get the latitudes and longitudes. The other issue to keep in mind is the load time.
Thanks

You can do this the easy way or the hard way. Depends on whether your condition that needs to be checked can be expressed in the form of a SQL where clause. If it can, then do what BKBK suggested, and use a query of query to create a new resultset that only has the rows from the original resultset that don't meet your condition.
If the calculation of the condition is more complex, then do a CFLOOP over the query and examine each row to see if you want to keep it or toss it. if you want to toss it, the delete that row - there is a function in CFLIB.ORG called querydeleterow that should help you. Or, you could just clear out the row's contents and then do the query of query as described in BKBK's post to create a new resultset that doesn't include the blank rows.

ABAP routine - looping a result set from table.

I am trying to access a table and pass the resulting rows to an internal table.
However, before passing, I need to do some data manipulation on one of the columns of the table and then pass it.
If I didn't have to do this, I could have just said
INTO CORRESPONDING FIELDS OF TABLE
But since I have do data manipulation, I cannot do this. This is what I am doing now.
SELECT * FROM /BI0/QEMPLOYEE WHERE JOB = '1234' AND DATETO = '99991231'.
MOVE /BI0/QEMPLOYEE-EMPLOYEE TO INT_EMP-EMPN.
MOVE /BI0/QEMPLOYEE-JOB TO STR1.
STR2 = STR1 + 0(4)
SEARCH STR2 FOR ' ' STARTING AT 1 ENDING AT 1.
IF SY-SUBRC EQ 0.
REPLACE ' ' WITH '0' INTO STR2.
ENDIF.
MOVE STR2 TO INT_EMP-FAC.
But this will move only one row. How can I move all the rows? Is there a loop that I can use? I can see a loop for internal tables but I need to loop the result set and then send it. I posted this question twice but haven't gotten the right answer.
Thanks.

Hi,
Are you trying to write the code in Update Routine or a Start Routine.?
If you want to update all the records, you can use the start routine.
So you need to use a loop for doing all the records.
If you are using a Update routine then you dont have to use the loop.
But here I recommend the Start Routine is the best choice.
Here is a document which can be helpful for you:

Looping through results of a Select through a DB adapter

I am selecting an unknown number of rows from a database through the DB adapter into my process. When I get these results I need to loop through them, but the examples I have seen require an attribute to define each row for the loop to work . My result set is not giving me an attribute and I do not see how to define one in the wizard used to define the adapter.
Is there a way to assign an attribute to each row automatically as it comes out or after the fact? Or is there another way to attack this problem that I do not see?
Thank you in advance for the help.
--Mike

you can take the results payload and loop thru with the while statement, then you can iterate thru each result and doing whatever you need to. Just make a counter variable of type int and count the number of records in the payload, then initialize a iterator varible on int and set to 0.
then just loops thru the payload and add +1 to iterator until it reaches the count number. This allows you to hit each records one by one, and do any kind of analysis on the current record set.

Problem while looping through record set and tem table for matching data

hi I am using one record set and ane temp table and looping through both to find the match between dates.
If date matches then it shud do some processing otherwise it will return default values(null values).
FOR i IN student_rec .FIRST..student_rec .LAST          /*student_rec.school_date has 01-MAR-2012,02-MAR-2012,03-MAR-2012,04-MAR-2012,05-MAR-2012*/

04-MAR-2012     70
05-MAR-2012     60          yes 10          20
but this as result
school_date     marks_obtained     has_csts     cst_present cst_absent
01-MAR-2012     20
02-MAR-2012     30
03-MAR-2012     40
04-MAR-2012     70
05-MAR-2012     60

I am getting a set values from a record set....student_rec
and on pipelining this record set from 1st till last
i am getting this
school_date     marks_obtained     has_csts     cst_present cst_absent
01-MAR-2012     20
02-MAR-2012     30
03-MAR-2012     40
04-MAR-2012     70
05-MAR-2012     60
so initially has_csts, cst_present and cst_absent is null for all dates.
now have a temp table of selected_dates(which contains these dates 02-MAR-2012,03-MAR-2012,05-MAR-2012)
now I am want to populate has_csts, cst_present and cst_absent with data only for those dates which is present in selected_dates temp table(02-MAR-2012,03-MAR-2012,05-MAR-2012) and that too has_csts, cst_present and cst_absent will be populated with some condition (based on the values from procedure got from P1 and P2).
so want result set to look like
school_date     marks_obtained     has_csts     cst_present cst_absent
01-MAR-2012     20
02-MAR-2012     30          yes 10          20
03-MAR-2012     40           yes 10          20
04-MAR-2012     70
05-MAR-2012     60          yes 10          20
so what could be the possible solution to obtained this....

Extra Space coming while looping through Hash Set in JSP: URGENT

Hi,
I have to loop through the Hash Set in jsp, and display the contents with a comma seperated list.
I am able to display the values withing the set, however.. after every value,
i am getting an extra space and then a comma. How do i get rid of this extra space?
Below is the code snippet
<% Set tagSet = new HashSet();
     tagSet = (Set)request.getAttribute(PhotoConstants.REQ_RELATED_TAGS);
     Iterator i = tagSet.iterator();
     while(i.hasNext()){
     String tagName=(String)i.next();
%>
<a href="/outlook/photo/keywords?keywords=<%=URLEncoder.encode(tagName)%>"><%=tagName%></a>
<%if(i.hasNext()==true){%>,<%}%>
<%}%>
I am getting following output:
NY , sky , Sports & Recreation , clouds , New York City , New York
Expected Output:
NY, sky, Sports & Recreation, clouds, New York City, New York
I want space after a comma, not befor comma...
Any help is really appreciated..
Thanks
Deepti

<% while(i.hasNext()) {
    String tagName=(String)i.next(); %>
    <a href="/outlook/photo/keywords?keywords=<%=URLEncoder.encode(tagName)
    %>"><%=tagName%></a><%if(i.hasNext()==true){ %>,<% } %>
<% } %>I think this is an html whitespace thing... try moving your code around to look like what's above (ie move the end of line to inside your scriptlet tag)
Code looks OK...

Looping through a set of data

seq     |     id|     Name|     TotalPc
1     |     22|     ABA |     20
1     |     23|     ABB |     20
2     |     24|     ABC |     20
3     |     25|     ABD |     20
3     |     26|     ABE |     20
3     |     27|     ABF |     20
4     |     28|     ABG |     20
5     |     29|     ABH |     20
6     |     30|     ABI |     20
6     |     31|     ABJ |     20
6     |     32|     ABK |     20
6     |     33|     ABL |     20The above result is returned in a resultset. What i would like to achieve is store these rows in an object that is structured as shown below
public class Name{
     String seq
     String name;
     Arraylist namePcs = new ArrayList()
public class NamePcs{
     String id;
     String totalPcs;
}Now as you can see in the data, some of the rows belong to the same element. For example, all those with seq=6 should be stored in the same object because they below to the same group i.e. 6.
I tried several combinations of approaches but i always seem to either miss the last one, duplicate them or exhaust the resultset.
Here are some examples of what i tried to do.
Example 1 - This example copies every name into every element.
while(rs.next()){
     Name name = new Name();
     name.seq = rs.getString("seq");
     name.name = rs.getStrign("name");
     NamePcs namePcs= new NamePcs()
     namePcs.id = rs.getString("id");
     namePcs.totalPcs = rs.getString("totalPcs")
     name.namePcs.add(namePcs);
seq_no = rs.getString("seq");
}Example 2 - In this example i try to save the child elements only if the seq number is the same but i still get duplicates.
String seq_no = "";
while(rs.next){
     if(!seq_no.equals(rs.getString("seq_no"){
               Name name = new Name();
               name.seq = rs.getString("seq");
               name.name = rs.getStrign("name");
     if(seq_no.equals(rs.getString("seq_no");{
          NamePcs namePcs= new NamePcs()
          namePcs.id = rs.getString("id");
          namePcs.totalPcs = rs.getString("totalPcs")
          name.namePcs.add(namePcs);
seq_no = rs.getString("seq");
}I also tried an inner while loop with an inner rs.next() but that exhausts the resultset. Is there a better way to do this? Thansk in advanc.e

Hi,
Sorry for not being clear enough. The above was just a quick example to try and show what i am trying to achieve.
What i am trying to achieve is to store the data in objects. The data itself has a one to many relationship. This means that many names will be related to the same sequence number. I would like to store the common names (i.e. those with the same seq no) in the same object in an arraylist.
Maybe this data structure makes more sense
public class seq{
     String seq
     Arraylist namePcs = new ArrayList() //will contain all names with the same sequence
public class NamePcs{
     String id;
     String name;
     String totalPcs;
}What im hoping to achieve is the following
- The seq object will contain one seq row (either 1,2,3,4,5,6)
- Array list in the seq object should contain all the rows for each individual seq.
- As an example if seq[3].seq = 6, the seq.namePcs() should contain all NamePcs objects tha t have id's (30,31,32,33).
Here is what i am hoping to achieve as the end result (for the first 6 rows)
seq[0]
     seq = 1
     namePcs[0]
          id = 22
          name = ABA
          TotalPcs = 20
     namePcs[1]
          id = 23
          name = ABB
          TotalPcs = 20
seq[1]
     seq = 2
     namePcs[0]
          id = 24
          name = ABC
          TotalPcs = 20
seq[2]
     seq = 3
     namePcs[0]
          id = 25
          name = ABD
          TotalPcs = 20
     namePcs[1]
          id = 26
          name = ABE
          TotalPcs = 20
     namePcs[1]
          id = 27
          name = ABF
          TotalPcs = 20               I hope that made it a bit clear.
Thanks

Need a Firefox script to loop through a set of web pages

Hi all,
I was wondering if anyone had come across a script for this purpose?
I need to power on a PC of mine, have it automatically start Firefox on startup (easy so far) then load a "loop" of predefined internal web pages that it keeps up on-screen for, say 5 seconds each webpage (5 pages in total that it would flick through)
Is it also possible to script or force Firefox to open in Full screen mode?
Thanks in advance,
Chris

Sounds more like you want a slide show, the only difference is if any of those web pages change. Quick check of addons: '''slide show seconds'''
'''[http://example.com Tab Slideshow]''' (13.3 KB) :: Add-ons for Firefox
-- Cycles through tabs as a slideshow. A minimalist extension that offers a configurable time to automatically switch to and display the next tab (and wrap around from the last to the first tab). The slideshow can be customized to auto-refresh tabs, as well as go into slideshow immediately when you open the browser. Extension offers a configurable time to automatically switch to and display the next tab (and wrap around from the last to the first tab).
Quick HOW TO: To start and stop the slideshow, find the "Start Tab Slideshow" menu item under the "Tools" menu (or with Firefox 4 on recent Windows versions, the orange Firefox app button). To change delay and refresh settings, go to the Add-ons Manager, find the extension in the list, and click the Options button (or "Preferences" on a Mac).

Result set null

Hello techies,
I am doing simple program, which is connecting to mysql server and retreiving the results from my database using servlets.
I want to do if the result set is returning zero rows i.e if there is no matching rows is available in the table, which i had specified in my query.
Here is my code
String url = "jdbc:odbc:testDSN";
Properties p = new Properties();
p.put("user", "root");
p.put("password", "kkkk");
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
conn = DriverManager.getConnection(url, p);
System.out.println("connection established");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select *from test.emp where empNumber =15");
System.out.println("resultset is null" + rs.wasNull());
if (rs.getRow() == 0) {
System.out.println("nomatching subject is found");
out.println("No Matching subject is found");
else {
out.println("<TABLE CELLSPACING=\"0\" CELLPADDING=\"3\" BORDER=\"1\">");
out.println("<TR><TH>eno</TH><TH>ename</TH><TH>date</TH></TR>");
// Loop through results of query.
while (rs.next() == true)
out.println("<TR>");
out.println("<TD>" + rs.getString("eno")+ "</TD>");
out.println("<TD>" + rs.getString("ename") + "</TD>");
out.println("<TD>" + rs.getString("date") + "</TD>");
out.println("</TR>");
Here if there are no employe record matching eno =15 in my table then i want to print no matching record is found.
where i am making mistake??
plz help me .
It is very urgent.
Thanks (inadvance)
regards,
ramu

Good Lord, you have database and HTML generation code in the same method?
This is not the way to do JDBC code. Start with a tutorial.
Ever read about object-oriented programming? How 'bout starting with an Employee class that has id, name, and date (what date? birth date? employment date? termination date?) as attributes. Then write a data access object that can do all the database stuff on Employee's behalf, without any consideration for UI. Test that on the command line until you have it working perfectly. THEN worry about how you'll display results to the user.
Your JDBC code isn't right. wasNull() checks to see if the column result is null, not the result set itself. (ResultSet can never be null; read the javadocs). You'd be getting a NullPointerException if ResultSet was null, wouldn't you?
Your code deserves a SERIOUS rewrite, which I'm not inclined to do for you. But I would recommend something more along these lines:
// hardwired url, driver, and query? oh, my - that's bad.
String url = "jdbc:odbc:testDSN";
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
conn = DriverManager.getConnection(url);
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("select * from emp where empNumber =15");
// you're obviously putting this in a servlet - bad idea.
// ever heard of JSPs?
out.println("<TABLE CELLSPACING=\"0\" CELLPADDING=\"3\" BORDER=\"1\">");
out.println("<TR><TH>eno</TH><TH>ename</TH><TH >date</TH></TR>");
// Loop through results of query.
while (rs.next())
out.println("<TR>");
out.println("<TD>" + rs.getString("eno")+ "</TD>");
out.println("<TD>" + rs.getString("ename") + "</TD>");
out.println("<TD>" + rs.getString("date") + "</TD>");
out.println("</TR>");

Create a CF Query Result Set in Java

I'd like to programatically build a ColdFusion query resultset inside of a Java class and return it to the calling application. See the Java psudocode below to see what I'm talking about:
public class MyClass {
     public coldfusion.sql.QueryTable getQuery() {
          // Create a query table object
          QueryTable myTable = ..?
          // Loop through some set of instance data for my class
          for(int c = 0; c < this.myWigets.length; c++) {
               int row = c+1;
               myTable.setField(row, nameCol, this.myWigets[c].name);
               myTable.setField(row, colorCol, this.myWigets[c].color);
          return myTable;
I've had stuff like this partially working in the past but had issues with things like query of queries and such probably due to the hacks used to create the QueryTable object. I'm mainly just checking in to see if there has been any progress made in this area. To me this seems like such an obvious thing for a Java developer working within CF to want to do. I'm surprised Adobe doesn't have an officially supported API for doing this sort of thing (or maybe I'm just too dumb to find it.) A few other notes... I'm not using CFX, and I'm not starting with a java.sql.ResultSet otherwise I would use the QueryTable(java.sql.ResultSet) constructor. I need to build this thing from scratch programatically.
Thanks for your time. I hope this question makes sense to someone out there.
- Mike

I appologize. I wasn't very clear with my original question.
I'm creating an instance of my Java class from within CF using createObject("java", "com.example.MyClass"). So based on the sample code in my original post on the CF side I'd like to do something like this:
<cfscript>
     myObj = createObject("java", "com.example.MyClass");
     myObj.doSomeStuff();
     myCFQuery = myObj.getQuery(); // Return a CF query from my java class
</cfscript>
... then do stuff like ...
<cfquery name="mySortedQuery" dbtype="query">
     select     *
     from       myCFQuery
     order      by color
</cfquery>
I appriciate your suggestions so far. I have other solutions working already but they are not ideal. I was just hoping someone had a clean and as-hack-free-as-possible way of creating a ColdFusion query result set in Java and passing it back to CF.
Thanks again,
Mike

Loop through a range of data

Hi guys
I have this set of numbers. 54 55 56 58 59 61 64 66. I want to loop through this set of number to give an array of result of 54 55 56 0 58 59 0 61 0 0 64 0 66.
Simply, i am trying to insert zero into the blank of the +1 interval in this set of number. I could not figure out how to do this.
Please help me thank you

How to loop through columns of a table?

Hi, guys
Is there a way to loop through each column of a table? If there is a way, then how?
I have a table with columns of different datatypes , and I want to set default values for each column with a loop but don't know how to make it happen.
For example,
Table: Employees
declare
rec Employees%ROWTYPE;
begin
for col in rec.empno .. rec.location loop
     if col = rec.empno then -- set default value for column empno;
end loop;
end;
/Sorry, I am a newbie to PL/SQL. Please help!
Thanks in advance.

Hi,
You can query the data dictionary views all_tab_columns (or user_tab_columns) to get the names of all the columns in a particular table.
Here's an easy way (but not a very efficient way) to loop through them:
SET     SERVEROUTPUT     ON
BEGIN
     FOR c IN ( SELECT column_name
                     FROM    all_tab_columns
              WHERE   owner     = 'SCOTT'     -- Remember ot use UPPER CASE inside quotes
              AND         table_name     = 'EMP'
     LOOP
          dbms_output.put_line (c.column_name || ' = column_name inside loop');
     END LOOP;
END;
/I'm confused about what you want to do, though.
Do you want the PL/SQL code to write and/or execute an ALTER TABLE command for each column?

Looping through 2 Result Sets - Not working-HELP!!

This code loops through my first result set fine.....so I take the first part number from the result set, do a second result set to bring back all part conditions associated with that part number and compare them to see if they are all the same. When it hits the second loop with the second result set, it only loops once. I know this because of my system.out.println only print once.....can someone see where I'm going wrong....thanks in advance....

Got the answer...changed my select statement in my second loop, did a group by CONDS which of course if they are all the same....the result set would only have one value therefore the loop will only execute once...took out the group by CONDS and ran fine....

Stepping through a query result set, replacing one string with another.

I want to write a function that replaces the occurance of a string with another different string. I need it to be a CF fuction that is callable from another CF function. I want to "hand" this function an SQL statement (a string) like this:   (Please note, don't bother commenting that "there are eaiser ways to write this SQL..., I've made this simple example to get to the point where I need help. I have to use a "sub_optimal" SQL syntax just to demonstrate the situation)
Here is the string I want to pass to the function:
SELECT
[VERYLONGTABLENAME].FIRST_NAME,
[VERYLONGTABLENAME].LAST_NAME,
[VERYLONGTABLENAME].ADDRESSS
FROM
LONGTABLENAME [VERYLONGTABLENAME]
Here is the contents of the ABRV table:
TBL_NM, ABRV    
VERYLONGTABLENAME, VLTN
SOMEWHATLONGTALBENAME, SLTN
MYTABLENAME, MTN
ATABLENAME, ATN
The function will return the original string, but with the abreviations in place of the long table names, example:
SELECT
VLTN.FIRST_NAME,
VLTN.LAST_NAME,
VLTN.ADDRESSS
FROM
LONGTABLENAME VLTN
Notice that only the table names surrounded by brackets and that match a value in the ABRV table have been replaced. The LONGTABLENAME immediately following the FROM is left as is.
Now, here is my dum amatuer attempt at writing said function: Please look at the comment lines for where I need help.
      <cffunction name="AbrvTblNms" output="false" access="remote" returntype="string" >
        <cfargument name="txt" type="string" required="true" />
        <cfset var qAbrvs=""> 
        <cfset var output_str="#txt#"> 
        <cfquery name="qAbrvs" datasource="cfBAA_odbc" result="rsltAbrvs">
            SELECT TBL_NM, ABRV FROM BAA_TBL_ABRV ORDER BY 1
        </cfquery>
     
    <cfloop index="idx_str" list="#qAbrvs#">      
    <cfset output_str = Replace(output_str, "#idx_str#", ) 
    </cfloop>               
        
    <cfreturn output_txt>
    </cffunction>
I'm mainly struggling with syntax here. I know what I want to happen, I know how to make it happen in another programming language, just not CF9. Thanks for any help you can provide.

One:
<cfset var output_str="#txt#"> 
No you do not need to create a local variable that is a copy of the arguments variable as the arguments scope is already local to the function, but you do not properly reference the arguments scope, so you leave yourself open to using a 'txt' variable in another scope. Thus the better practice would be to reference "arguments.txt" where you need to.
Two:
I know what I want to happen, I know how to make it happen in another programming language, just not CF9.
Then a better start would be to descirbe what you want to happen and give a simple example in the other programming language. Most of us are muti-lingual and can parse out clear and clean code in just about any syntax.
Three:
<cfloop index="idx_str" list="#qAbrvs#">      
I think you want to be looping over your "qAbrvs" record set returned by your earlier query, maybe.
<cfloop query="qAbrvs">
Four:
<cfset output_str = Replace(output_str, "#idx_str#", ) 
Continuing on that assumption I would guess you want to replace each instance of the long string with the short string form that record set.
<cfset output_str = Replace(output_str,qAbrs.TBLNM,qAbrs.ABRV,"ALL")>
Five:
</cfloop>               
If this is true, then you are looping over the record set of tablenames and abreviations that you want to replace in the string.

Result set looping and arrays??????????

Hey i have a result set problem in using an applet connected to a database.
After i have accessed a database, i am using a result set to store these values, then put them into arrays to out put to screen. im using:
count = 0;
while(rs.next())
lecturer[count] = rs.getString("FirstName") + " " + rs.getString("Surname");
room[count] = rs.getString("Room_No");
sentence = rs.getString("Subjects");
if(sentence.length()>12)
space = sentence.indexOf(" ");
subject[count] = sentence.substring(0,(space));
subject2[count] = sentence.substring((space+1),sentence.length());
else
subject[count] = sentence;
subject2[count] = " ";
timeslot[count] = rs.getInt("Time_slot");
count++;
resCount++;
rs.close();
stm.close();
The while is there untill there are no more values in the result set. This should work(in theory). But for some reason the while loop goes around and around until 'size' (which is the size for all the arrays) is reached. This is a set value at the start of the applet. But whenever i change it the while loop goes around that many times without fail. this results in duplicate outputs to screen, that i dont want.
Anyone got any ideas????????????

This flow doesn't make too much sense to me. Why are you setting an absolute limit on the length of the array, if it should really be determined by the number of rows in your resultset. It sounds like you would be better off using a Collection class, like:
List names = new ArrayList();
while(rs.next()) {
names.add(rs.getString("name"));
}
