Unable to loop through a ResultSet (Classic ASP, ADO)

All,
I have inherited a legacy web site and have encountered a problem that I can't get figure out:
The program structure is as follows:
1. Execute a SQL Server Stored proc and create XML from the result set
2. If a condition is met, exceute a second stored proc and hydrate the XML from step one with some more tags
3. return the XML is the response
Step 1 happens without problems, but when the condition is met the execution halts as soon as I try to do anything with the Result Set. For instance set
RS.ActiveConnection = nothing or do until CustodianRS.EOF both halt execution. and I end up with an empty Response.
Here is the offending code:
if len(trim(strTradingArea)) = 4 then
dim CustodianCN
dim CustodianCMD
dim CustodianRS
dim node
set CustodianCN = server.CreateObject("ADODB.Connection")
CustodianCN.CursorLocation = adUseClient
CustodianCN.Open Application("PANORAMA_SACDETAILS")
set CustodianCMD = server.CreateObject("ADODB.Command")
with CustodianCMD
set .ActiveConnection = CustodianCN
.CommandType = adCmdStoredProc
.CommandTimeout = 300
.CommandText = "p_SACGetAccountCustodiansByTradingArea"
.Parameters("@TradingArea").Value = strTradingArea
set CustodianRS = .Execute
end with
'set CustodianRS.ActiveConnection = nothing
CustodianRS.Sort = "Custodian"
do until CustodianRS.EOF
set node = responseXML.createElement("custodian")
node.setAttribute "id",trim(CustodianRS.Collect("Custodian") & "")
node.setAttribute "parent",trim(CustodianRS.Collect("Parent") & "")
responseXML.firstChild.appendChild(node)
CustodianRS.MoveNext
loop
end if
Does anyone have any suggestions? Any help would be much appreciated, I have already spent a considerable amount of time on this.
Thanks!

I had a minute or two. Here are some things to think about:
I removed all unnecessary lines of code and indented correctly. What I immediately see is that you have no error management. There is also no way to detect an empty recordset.
set CustodianCN = server.CreateObject("ADODB.Connection")
CustodianCN.Open Application("PANORAMA_SACDETAILS")
set CustodianCMD = server.CreateObject("ADODB.Command")
with CustodianCMD
set .ActiveConnection = CustodianCN
.CommandType = adCmdStoredProc
.CommandTimeout = 300
.CommandText = "p_SACGetAccountCustodiansByTradingArea"
.Parameters("@TradingArea").Value = strTradingArea
set CustodianRS = .Execute
end With
CustodianRS.Sort = "Custodian"
do until CustodianRS.EOF
set node = responseXML.createElement("custodian")
node.setAttribute "id",trim(CustodianRS.Collect("Custodian"))
node.setAttribute "parent",trim(CustodianRS.Collect("Parent"))
responseXML.firstChild.appendChild(node)
CustodianRS.MoveNext
loop
My suspicion is that you did not write this. If you are just trying to change or migrate a web page then I recommend contacting a consultant. Using a database from a web page is a very tricky task. If you are not a developer it is highly
unlikely that you will be able to get it to work.
¯\_(ツ)_/¯

Looping through 2 resultsets simultaneously

I need to set up a loop in which I loop through 2 ResultSets simultaneously and compare them. I have tried to use a simple while (RS1.next() || RS2.next() ), but when I try to read data from RS2 I get an "Invalid Cursor state" error. From my experience with these errors, I think it just means that RS2 isn't looping, but I don't know how to fix it.
Here's the loop I have:
while (RS1.next() || RS2.next() ) {
<%=RS1.getString("Name")%> <%=RS2.getString("Name")%>
And just to avoid any confusion, what I have written is correct, both tables have a field called 'Name'.
Can someone please help me?

Unfortunately, there is not necessarily a one-to-one relationship between the Note and Message. However, I am actually using 2 separate statement objects for the resultsets. I know exactly what you mean if there was in fact a 1-to-1 relationship, but unfortunately, since there isn't, I need 2 resultsets. I have tried a few other things since I wrote this and have come close. Here is what I've tried, so others know:
I've tried using a boolean variable set to true at the beginning and if, after going through the loop, I am at the end of both recordsets, I set it to false. This worked when I didn't have any elements in one of the tables, but, for one reason or another, when I had data in both tables, I got the same Invalid Cursor State error.
I've also tried using 2 separate boolean variables, one for each of the fields, but this also gives me this error.
So if anyone else has any ideas to help me out, I'd appreciate it.

Loop through Query String in ASP

Hi,
I am new to ASP and am trying to loop through values in a
query string
separated by a comma, for example:
/site/search/results.asp?ids=19736a,20248a,14952a,19956a
I need to construct SQL from this something like
SELECT * FROM MyTable WHERE
ID = 19736a OR
ID = 20248a OR
ID = 14952a OR
ID = 19956a
I am just unsure on how to separate all the values from the
query string.
Thanks for your advice.

Oh, in the example below there is no space between the id
numbers in the
querystring.
eg. ids=1,23,456,2
If you do have spaces then you need to adjust the split
accordingly
eg. ids=1, 23, 456, 2
you would use myIdArray=split(idStr,", ")
note the space after the comma.
just make sure you always use the same format in your
querystring

Hi
I need to loop through the result set how would i do that here is my scenario
in the database i have total 10 columns say an example
a,b,c,d,e,f,g,h,i,j,k and assume i have 100 rows with allthese values in the database now for these 100 rows i have to calculate the summary of those columns and i have written formula something like this but it was not working it was giving me zero dont know plz advise on this
whileprintingrecords;
numbervar totalsum;
totalsum=totalsum((a-b)/100cdefghi-j-k);
and i want to display this sum in my detail section of report how would i do that

Try this and see if you get any results.
totalsum=totalsum((a-b)/100cdefghi-j-k);
totalsum := totalsum((a-b)/100cdefghi-j-k);

Populate Local XML File, and Loop through it

I created a local property of type XML. I want to populate this variable with the results of a SQL query, and store it in local memory. Then later, I will loop through this file and perform actions. Basically I am going to have to loop through this resultset many times, and if I can store it in memory, I won't have to re-qurey the DB>
#1 Is this possible?
Right now, I use a repeater on the SQL, and assign the rowset/rowset/row to the local XML Variable.(Assign XML). SHould I use Assign XML, or APpend XML for the Link Type
THen later I am trying a repeater to loop through the flle, and I have no idea where to point the xpath expression to.
Thanks for the help in advance,
JEff

From what I understand you are trying to do - Rather than repeating on the SQL query you can link the "Result" of the SQL Query action to the local property (type xml) [and yes you just say Assign XML instead of Append or anything else].
What this would do is assign the local variable the results of the SQL Query in an xMII XML format and then you can further work on this XML.
But rather than using the local variable you can repeat on the SQL Query Action (the way you are doing currently) and manipulate what ever you want to. There is no question of requerying the DB as ur DB would be queried only one time (the SQL Query Action Block will ensure this) and then the repeater would be repeating only on the resulset rendered by the SQL Query action.
Did this make it clearer or have I not understood your problem?

How to loop through classic report rows?

Hi,
I have a page that has a classic report region. Can I somehow loop through the rows in the report result?
If I put a checkbox item in the query then using this works fine, but I would not like to add checkbox I just would like to loop through the records.
FOR I in 1..APEX_APPLICATION.G_F02.COUNT LOOP
Do something with record having checkbox item value APEX_APPLICATION.G_F02(i);
END LOOP;
TIA,
Tamas

Andy,
What I would like to do is to let the user click a report row, then navigate to a detail form page and display detailed information of the given report row. And should the suer decide to have a look at all the records, then let him/her click a next button on the detail form and display the next row in the report result on the detail form.
Thanks for the tip. if there is no other way, I will probably do this way.

How do I loop through tables, not columns in a table?

Sorry if this is a long one. My problem is actually quite simple. I am trying to write either an ad hoc PL/SQL block or a stored procedure to loop 18 times (thru 18 tables) and perform a SQL query on those tables, returning 18 resultsets. I would like the results to show up on the screen (or in a spool file, whatever).
So far I have tried 3 different approaches, none of which have worked.
1. I tried to assign the select query to a variable (qry) and use EXECUTE IMMEDIATE qry. This forced me thru a variety of errors to declare variables and assign the result to them--EXECUTE IMMEDIATE qry into nm0, nm1, nm2...
The problem with that was the resultset returned more than the variable was built for as there might be no rows returned, or it might be a thousand rows of data. So I tried changing the variables to VARRAYS, but it gave me a type mismatch as the underlying columns were NUMBER and VARCHAR2.
DECLARE
     ctr number;
     TYPE NUMLIST IS VARRAY (1000) OF NUMBER;
     TYPE VARLIST IS VARRAY (1000) OF VARCHAR2(15);
     nm0 NUMLIST NOT NULL DEFAULT 1;
     nm1 VARLIST;
     nm2 NUMLIST NOT NULL DEFAULT 1;
     nm3 VARLIST;
     nm17 NUMLIST NOT NULL DEFAULT 1;
     qry VARCHAR2(2000) := 'klx_uln_p000_cells';
BEGIN
FOR ctr IN 1..17 LOOP
     IF ctr < 10 THEN
          qry := 'SELECT
          A.DIM_0_INDEX,
          S0.SYM_NAME,
          A.DIM_1_INDEX,
          S1.SYM_NAME,
          A.DIM_2_INDEX,
          S2.SYM_NAME,
          A.DIM_3_INDEX,
          S3.SYM_NAME,
          A.NUMERIC_VALUE,
          B.NUMERIC_VALUE
          FROM
          KHALIX.klx_uln_p00'||ctr||'_cells A,
          KHALIX.klx_ucn_p00'||ctr||'_cells B,
          KHALIX.KLX_MASTER_SYMBOL S0,
          KHALIX.KLX_MASTER_SYMBOL S1,
          KHALIX.KLX_MASTER_SYMBOL S7
          WHERE
          A.DIM_0_INDEX=B.DIM_0_INDEX AND
          A.DIM_1_INDEX=B.DIM_1_INDEX AND...
          A.DIM_7_INDEX=S7.SYM_INDEX';
     ELSE
          qry := 'SELECT
          A.DIM_0_INDEX...
          A.DIM_7_INDEX=S7.SYM_INDEX';
     END IF;
     BEGIN
     dbms_output.put_line('SELECT FOR KLX_ULN_P00'||ctr||'_CELLS');
     dbms_output.put_line(nm16);
     dbms_output.put_line(nm17);
     EXECUTE IMMEDIATE qry into nm0,nm1,nm2,nm3,nm4,nm5,nm6,nm7,nm8,nm9,nm10,nm11,nm12,nm13,nm14,nm15,nm16,nm17;
--     dbms_output.put_line(qry);
     dbms_output.put_line(nm16);
     dbms_output.put_line(nm17);
     EXCEPTION
          WHEN NO_DATA_FOUND THEN
               dbms_output.put_line('No data found for Query '||ctr);
     END;
END LOOP;
EXCEPTION
     WHEN NO_DATA_FOUND THEN
          dbms_output.put_line('No data found for Query '||ctr);
END;
2. So then I used REF CURSOR to create a stored procedure and return the values. That allowed me to run my query AND tokenize the tablenames with a counter so that it would loop through the different tables! However, I still could not get it to display the results without going to SQL Plus and typing 'print c;'.
3. So, finally I tried to create a looping wrapper around the ref cursor to have some variable (ctr) increment so my query would get performed on table0_cells through table17_cells. This, too, did not work.
If I manually go to SQL Plus and type:
variable ctr number
begin
:ctr := 1;
end;
exec dupe_find(1,:c);
it will execute for the first table (klx_uln_p001_cells) and I can then type 'print c' to see what was returned. But when I try putting this within a wrapper PL/SQL block with a Loop to make ctr go from 0 - 17 (to loop through table_names klx_uln_p000_cells to klx_uln_p017_cells), it does not work.
Help! It should be very simple to loop through tables, shouldn't it? I just want a script that will loop through tables, perform a query on each table and display the results. For some reason, I can only find documentation examples on looping through columns that are all in the same table.
Dave

Here's a working example using your first strategy ...
create table t1 (id number);
create table t2 (id number);
insert into t1 values (100);
insert into t1 values (101);
insert into t2 values (200);
insert into t2 values (201);
declare
v_table_name user_tables.table_name%type;
type ttab_id is table of t1.id%type index by binary_integer;
tab_id ttab_id;
begin
for i in 1 .. 2 loop
v_table_name := 't' || i;
execute immediate 'select id from ' || v_table_name
bulk collect into tab_id;
dbms_output.put_line('query from ' || v_table_name);
for j in 1 .. tab_id.count loop
dbms_output.put_line(tab_id(j));
end loop;
end loop;
end;
There are many other ways to do this (especially if you need to do more than just print out the data).

Classic ASP - "ORA-01722: invalid number" using OraOLEDB.Oracle driver

I am working on doing some maintenance updates to a Classic ASP website, and I need to be able to run an insert/update statement for putting values into a lookup table. I am currently running into an "ORA-01722: invalid number" error when trying to use ADO and bind variables for my insert statement.
Below is an example of a table that I am having problems with:
CREATE TABLE "MATMGR"."TEST_SWING_TABLE"
(     "TABLE1_ID" NUMBER(4,0) NOT NULL ENABLE,
     "TABLE2_ID" NUMBER(4,0) NOT NULL ENABLE,
     CONSTRAINT "TEST_SWING_TABLE_PK" PRIMARY KEY ("TABLE1_ID", "TABLE2_ID")

Here is some snippet code of the basic functionality I am trying to get to work:
''START CODE''
Dim connDb, cmdDoseInsert
Set connDb = Server.CreateObject("ADODB.Connection")
connDb.CursorLocation = adUseClient ' Setup to return RecordSet
connDb.ConnectionString = "Provider=OraOLEDB.Oracle;Data Source={host};User ID={user id};Password={password}"
connDb.Open()

cmdDoseInsert.NamedParameters = true ' Set the command object to use named parameters
cmdDoseInsert.Prepared = true
cmdDoseInsert.CommandTimeout = 0
cmdDoseInsert.CommandText = "INSERT INTO TEST_SWING_TABLE (TABLE1_ID, TABLE2_ID) VALUES (:P_TABLE1_ID, :P_TABLE2_ID)"
cmdDoseInsert.Prepared = true

cmdDoseInsert.Parameters.Append cmdDoseInsert.CreateParameter("P_TABLE2_ID", adNumeric, adParamInput)

     cmdDoseInsert.Parameters(1).Value = {some numeric value}
     cmdDoseInsert.Execute
'... END: Looping
''END CODE''
What I have been able to find out so far is that there is some type of issue with numeric values getting translated right when sending two and retrieving from Oracle in ASP. So, does anyone have any thoughts on how to resolve this as I would like to use parameterized SQL to improve application performance?
I am connecting to a developmental server running Oracle 9.2

Ok, in my slightly larger example I found out that for what ever reason my named parameters are not being enforced, and so I had to make sure that the parameters were in the same order as they appeared in the SQL. To be on the save side, I did this when they were added as well as when I was assigning values to them.
Can anyone tell me if this is an Oracle issue or a ASP issue?

Loop through checkbox in Oracle APEX 4.2 (using JQuery Mobile)

Hello!
I want question text and a report containing the possible answers is shown on a page. An answer can be selected by clicking on the checkbox. After hitting the submit button, the selected checkboxes containing the Answer Text, an answer_id and the current session_id are to be inserted into a table within the database.
Within Oracle APEX 4.2, I am using a classic report to achieve this. Thich is actually a bad solution, because the checkboxes within the report are shown as simple HTML checkboxes, instead of neat JQueryMobile checkboxes). Anyway, this is my current solution:
Is use this code for creating the classic report:
SELECT APEX_ITEM.CHECKBOX(1,answer_id), answer_id, answer_text
FROM ANSWERS
WHERE question_ID = :P10_Question_ID;
The insert of the data is done via the on submit process "On Submit - After Computations and Validations"
This is the code for the on submit process:
DECLARE var_session_id NUMBER := :P0_SESSION_ID;
BEGIN
FOR i in 1..APEX_APPLICATION.G_F01.COUNT LOOP
INSERT INTO STUDENT_ANSWERS (answer_id, answer_text, session_id)
SELECT a.answer_id, a.answer_text, var_session_id
FROM ANSWERS a WHERE a.answer_id = APEX_APPLICATION.G_F01(i)
END LOOP;
COMMIT;
END;
But this solution does not work. Instead, nothing is inserted into the database.
I don't know why the process is not inserting into the database, maybe there is something wrong with this line here WHERE a.answer_id = APEX_APPLICATION.G_F01(i) ?
I even tried a simple update process for testing purposes, but this doesnt work either:
BEGIN
FOR i in 1..APEX_APPLICATION.G_F01.COUNT LOOP
UPDATE STUDENT_ANSWERS SET text = APEX_APPLICATION.G_F03(APEX_APPLICATION.G_F01(i))
WHERE am_id = APEX_APPLICATION.G_F02(APEX_APPLICATION.G_F01(i));
END LOOP;
COMMIT;
END;
Can anybody tell me how to loop through a checkbox within ORACLE APEX 4.2 and how to insert the values ANSWER_ID, ANSWER_TEXT and SESSION_ID into the table STUDENT_ANSWERS after hitting the submit button? If you would know how to do it without using a report but a simple checkbox, this would be even more helpful for me!

I would start by putting this after submit, to check the contents of the array.
apex_debug.message('count:'||apex_application.g_f01.COUNT);
FOR i IN 1..apex_application.g_f01.COUNT LOOP
apex_debug.message('i:'||i||':'||apex_application.g_f01(i));
END LOOP;
Then compare the contents with your answers table.

Problem looping through recordset

Hi,
I am having a problem with the following code. In the test case, the recordset returns more than one record. Only one record is inserted, and the loop aborted after the insert. If I take out the insert statement the loop cycles through for every record. I do not believe there is anything wrong with the insert statement, as the first record is inserted. Any help would be appreciated.
while(rs.next()){
                 System.out.println("test");
                 String equip = rs.getString("EQUIP");
                 String pm = rs.getString("PM");
                 String lim = rs.getString("LIMIT");
                 String item_val = rs.getString("ITEM_VALUE");
                 String source = rs.getString("SOURCE");
                 myStatement.executeQuery("INSERT INTO TESTTBL(ACTION,STATUS,TOOL,REMARK) VALUES('STACK VALIDATION','UPDATED', '" + equip + "','LIMIT: " + lim + " - VALUE: " + item_val + " SOURCE: " + source + "')");
                 System.out.println("INSERT INTO TESTTBL(ACTION,STATUS,TOOL,REMARK) VALUES('STACK VALIDATION','UPDATED', '" + equip + "','LIMIT: " + lim + " - VALUE: " + item_val + " SOURCE: " + source + "')");
             }

Did rs come from myStatement?
From http://java.sun.com/j2se/1.4.2/docs/api/java/sql/ResultSet.html :
A ResultSet object is automatically closed when the Statement object that generated it is closed, re-executed, or used to retrieve the next result from a sequence of multiple results.
You have to use two different statements: one for the rs that you're looping through and one for the insert that occurs while still using the first rs.

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.

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....

Trying to loop through records

Hi
I trying to loop through my records and write to a database each time, but my code only seems to write the first time through...
          //check for the stock levels...
          Iterator stockLevels = getItems().iterator();
          pstmt = dbConn.prepareStatement(sql_bundle.getString("findStock"));
          while (stockLevels.hasNext()) {
               CartItem stockL = (CartItem) stockLevels.next();
               pstmt.setString(1, stockL.getProduct().getISBN());
               ResultSet rscp = pstmt.executeQuery();
               if(rscp.next()){
                    if (rscp.getInt("STOCK_LEVEL") > stockL.getQuantity()) {
                         int newAmount = rscp.getInt("STOCK_LEVEL") - stockL.getQuantity();
                         PreparedStatement pstmte = dbConn.prepareStatement(sql_bundle.getString("updateStock"));
                         pstmte.setInt(1, newAmount);
                         pstmte.setString(2, stockL.getProduct().getISBN());
                         pstmte.executeUpdate();
                    } else {
                         cat.error("Right Bloddy mess");
                             throw new Exception();
               }else{
                    throw new Exception("No results from known good query.");
          pstmt.close();I get the following error in my browser:
org.apache.jasper.JasperException
     at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:248)
     at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:289)
and no errors when I compile using javac...
Thanks

excellent my looping is working...
thanks

Looping through Collection

Hello I need to loop through the collection to process 500 records at a time from the resultset.
how do i do this?
I have created another variable of same type as resultset output variable type. but not sure how to assign nodes 1 to 1000 to the new variable.

Hi,
You can loop over your collection with a while loop. The following is from the bpel samples directory (112.Arrays) adapted to your needs. Define the variables:
<variable name="iterator" type="xsd:integer"/>
<variable name="count" type="xsd:integer"/>
<variable name="xpath" type="xsd:string"/>
Set the initial values:
<assign name="SetInitialValues">
<copy>
<from expression="1"/>
<to variable="iterator"/>
</copy>
<copy>
<from expression="ora:countNodes('input', 'payload','/tns:collection/tns:item')"/>
<to variable="count"/>
</copy>
</assign>
Make a while loop:
<while condition=" bpws:getVariableData('count') >= bpws:getVariableData('iterator')">
<sequence>
<assign name="setAttribute">
<copy>
<from expression="concat('/tns:collection/tns:item[',bpws:getVariableData('iterator'),']/tns:value')"/>
<to variable="xpath"/>
</copy>
<copy>
<from expression="bpws:getVariableData('input','payload',bpws:getVariableData('xpath'))/>
<to variable="output" part="payload" query="/tns:recordVariable/tns:value"/>
</copy>

<copy>
<from expression="bpws:getVariableData('iterator') + 1"/>
<to variable="iterator"/>
</copy>
</assign>
</sequence>
</while>
So the trick is to dynamically build an xpath expression based on the while loop counter.
Kind Regards,
Andre

Looping through records... LC 8.0

Hi there
It seems easy enough to get the first record from a DB into a Form - but for the life of me I cannot find a way to loop through all the records (like mail merge) and enter all the records?
Could someone please point me in the right direction?
Thanks

Hi Paul
That method would appear to be dependent upon a click method with buttons.
Apart from the fact that it is time consuming, I can get the end result using .NET and iTextSharp (or ActivePDF Toolkit in asp.NET) to produce 'bulk' pdf documents by loading everything into a DataTable and running through a For loop for each row in the DataTable.
These forms would be a 'one off' for each new Customer, with an average of 120 records, so was looking for a 'quick and dirty' approach - as you may gather we have LC but not used it very much at all, so perhaps I was missing something!
