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.

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
I Appreciate your help.

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

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.

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 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).

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....

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();

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

Nested Loops...looping through one month of data at a time year by year

Hi all,
I'm trying to create an insert statement that loops through a table that has 10 years of data (2001 to 2010) month by month to minimize impact on server and commits more frequently to avoid filling up the redo logs and rollback tablespaces. The table is large, has about 40 millions records per year. Lets say the structure of the table is the following:
Customer_ID number(9),
Order_Item_1 number(6),
Order_Item_2 number(6),
Order_Item_3 number(6),
Order_date date
The table is in flat format but I want to normalize it so that it looks like the following:
Customer_ID Order_Seq Order_Item Order_date
999999999 1 555555 01-jan-2001
999999999 2 666666 01-jan-2001
999999999 3 444444 01-jan-2001
888888888 1 555555 03-jan-2001
888888888 2 666666 03-jan-2001
But because I want to loop through month by month....I need to set it up so that it loops through month by month, year by year (Using the Order Date Field) and Order_item by Order_item. Something like:
so my insert statements would be something like if I hardcoded instead of put the insert statement into a loop:
insert into orders_normalized

Hope this makes sense.

Does the sequence of items in an order really matter? In other words, do we really need to preserve that an item was in position 2 versus position 1? I bet that the sequence or position of each item in an order is not meaningful. They were probably numbered 1, 2, and 3 just to make them uniquely named columns so there would be three slots to hold up to 3 items in the denormalized table.
You only have about 400 million rows to insert, so it could feasibly be done in a single transaction (depending on your database environment).
You can always do a create table as select (CTAS) to help with undo / redo issues and get better performance. You could run it in parallel, and spit it out to a new table partitioned by month. Single DDL statement running in parallel making your new table--sounds good to me.
How about something like this:
CREATE TABLE ORDERS_NORMALIZED
(CUSTOMER_ID, ORDER_ITEM, ORDER_DATE)
PARTITION BY RANGE(ORDER_DATE)
PARTITION p200901 VALUES LESS THAN (TO_DATE('200902','YYYYMM')),
PARTITION p200902 VALUES LESS THAN (TO_DATE('200903','YYYYMM')),
PARTITION p201012 VALUES LESS THAN (TO_DATE('201101','YYYYMM'))
as SELECT CUSTOMER_ID, ORDER_ITEM_1, ORDER_DATE
   FROM OTHER_TABLE
   WHERE ORDER_ITEM_1 IS NOT NULL
   UNION ALL
   SELECT CUSTOMER_ID, ORDER_ITEM_2, ORDER_DATE
   FROM OTHER_TABLE
   WHERE ORDER_ITEM_2 IS NOT NULL
   UNION ALL
   SELECT CUSTOMER_ID, ORDER_ITEM_3, ORDER_DATE
   FROM OTHER_TABLE
   WHERE ORDER_ITEM_3 IS NOT NULL.....................
Out of curiosity, why not normalize it further? You could have used two tables instead of one.
One (ORDER) with:
ORDER_ID
CUSTOMER_ID
DATE
Order_id would be a new surrogate key / primary key.
Another table (ORDER_ITEM) with:
ORDER_ID
ORDER_ITEM
It would be a table that links ORDERS to ITEMS. You get the idea.

Text is not being displayed in sync on a label when looping through a list -- how to fix?

I have a list of states (50 states). I loop through this list (in a winform app -- VS2012) and want to display the current state ID that is being processed in the loop in the text property of a label. I precede the label.Text = StateID line with
Application.DoEvents() but I am also (in Debug mode) writing the same text to the console. The console displays correctly, but there appears to be a lag in the label.Text property
List<string> StateList = new List<string> { "al", "ak", "az","ar","ca","co","ct","de","fl","ga",...};
foreach (string stateID in StateList)
Application.DoEvents();
lblStateID.Text = "State is " + stateID; //--there is a lag here
I vaguely recollect something about a NotifyPropertyChanged event. I know this is common in WPF, but is there something similar in winform? Or is there a way to make the desired text to be displayed in the label.Text property in synchronization
with the loop?

Thank you. This is way simpler than implementing the INotifyPropertyChanged Interface. Although, here is an article on the INotifyPropertyChanged Interface and event

Automator - Loop through a text file and process data through a 3rd party software

Just stumbled on Automator the other day (I am a mac n00b) and would like to automate the processing of a text file, line-by-line, using a third party tool. I would like Automator to loop through the text file one line at a time, copy the string and keep as a variable. Next, place the variable data (copied string) into the text field of the 3rd party software for processing. Once the processing is complete, I would like Automator to fetch the next line/string for processing. I see items like "copy from clipboard" and "variables" within the menu but I am not finding much documentation on how to utilizle this tool. Just hear how potentially powerful it is.
The 3rd party software is not a brand name, just something made for me to process text. I may have to use mouse clicks or tabs + [return] to navigate with Automator. A term I heard on Bn Walldie's itunes video series was "scriptable software" for which I don't think this 3rd party app would be.
Kind regards,
jw

Good news and bad news...
The good news is that it should be entirely possible to automate your workflow.
The bad news is that it will be a nightmare to implement via Automator, if it's even possible.
Automator is, essentially a pretty interface on top of AppleScript/Apple Events, and with the pretty interface comes a certain stranglehold on features. Knowing how to boil rice might make you a cook, but understanding flavor profiles and ingredient combinations can make you a chef, and it's the same with AppleScript and Automator. Automator's good at getting you from points A to B but if there are any bumps in the road (e.g. the application you're using isn't scriptable) then it falls apart.
What I'm getting at is that your requirements are pretty simple to implement in AppleScript because you can get 'under the hood' and do exactly what you want, as opposed to Automator's restricted interface.
The tricky part is that if no one else can see this app it's going to be hard to tell you what to do.
I can give you the basics on reading a file and iterating through the lines of text in it, and I can show you how to 'type' text in any given application, but it may be up to you to put the pieces together.
Here's one way of reading a file and working through each line of text:
-- ask the user for a file:
set theFile to (choose file)
-- read the file contents:
set theFileContents to (read file theFile)
-- break out the lines/paragraphs of text:
set theLines to paragraphs of theFileContents
-- now iterate through those lines, one by one:
repeat with eachLine in theLines
-- code to perform for eachLine goes here
end repeat
Once you have a line of text (eachLine in the above example) you can 'type' that into another application via something like:
tell application "AppName" to activate
tell application "System Events"
tell process "AppName"
keystroke eachLine
end tell
end tell
Here the AppleScript is activating the application and using System Events to emulate typing the contents of the eachLine variable into the process. Put this inside your repeat loop and you're almost there.

Forms 6i loop through datablock question

I am writing a piece of code to loop through items with in a datablock to programmatically set the width between each field.
I created my data block through the wizard, but then manually added some fields. I have them listed in the order I expect them to be navigated, which is the order I expect them to appear on the screen.
When I am looping through the data block, I was assuming that next_item would go to the next navigable item, and it doesn't.
For example, I have items received_today, worked_today, total_waiting, total_for_today, total_calls, total_priority.
When the code loops through the data block, it actually loops in this order: received_today, worked_today, total_callbacks, total_priority, total_waiting, total_for_today.
I even set the next navigation item property for each item, but that didn't help.
My questions:
1. Is there a way to control what order the data block loops through items?
2. Why does this line get_item_property(get_block_property(block_name, FIRST_ITEM), x_pos); sometimes return null? (in my "proof of concept" form it returns a value, but the form I am modifying does not)
Following is my code:
PROCEDURE set_x_y_positions IS
     current_x_position pls_integer;
     current_y_position pls_integer;
block_name varchar2(30) := 'BLOCK22';
CurrentItem varchar2(30);
BEGIN
go_block(block_name);
current_x_position := get_item_property(get_block_property(block_name, FIRST_ITEM), x_pos);
current_y_position := get_item_property(get_block_property(block_name, FIRST_ITEM), y_pos);
      go_block(block_name);
loop
     BEGIN
            if :system.cursor_item <> (block_name || '.' || get_block_property(block_name, FIRST_ITEM))
                 and get_item_property(:system.current_item, displayed) = 'TRUE' then
              SET_ITEM_PROPERTY(:system.current_item, x_pos, current_x_position + 38);
              current_x_position := get_item_property(:system.current_item, x_pos);
            end if;
            if :system.cursor_item = 'BLOCK22.INTERNATIONAL' THEN--block_name || '.' || get_block_property(block_name, LAST_ITEM) then
                      exit;
            else
                 next_item;
            end if;
       END;
end loop;
END;I am using Forms 6i version 6.0.8.26.0
Thank you!
Katia

I do have an exit, and yes it does run well.
     if :system.cursor_item = 'ATS_MON_REPORTING_QUEUES_VW.INTERNATIONAL' THEN--block_name || '.' || get_block_property(block_name, LAST_ITEM) then
                      exit;
            else
                 next_item;
            end if;That redundant go_block is there because I had some output going to a dummy field in another block, so I had to make sure it was navigating back to the block. But yes, in this code example, that go_block is redundant.
Thank you, adding the
current_x_position := get_item_property(block_name||'.'|| get_block_property(block_name, FIRST_ITEM), x_pos);
current_y_position := get_item_property(block_name||'.'|| get_block_property(block_name, FIRST_ITEM), y_pos); worked perfectly.

How to loop through the "On My Mac" folders in mail?

Hi there - i am new to applescript, but am slowly working out how to use it.
I am stumped on how to write a rule that will move a message to a folder identified by a tag in a message (I am using MailTags).
I have script that will take the first tag and move the message to a mail folder in a fixed location (e.g. Archive/<tag name>) however I wanted to make it more generic by looping over all of my mail folders and finding one that matched the tag name.
However I am stumped on how to loop over all of my mail folder names - I have tried:
repeat with aFolder in (every mailbox of (mailbox for "ON MY MAC"))
and
repeat with aFolder in every mailbox of inbox
etc.
but none of these seem to work.
Is there some magic syntax to do this, so that I can do:
if (name of aFolder = msgTag) then
move oneMessage to mailbox (name of aFolder)
end if
Tim

You don't necessarily need to assign a variable to the entire list in order to loop through them (unless you really want to) - for example:
tell application "Mail" to repeat with aFolder in (get mailboxes)
-- do stuff with aFolder
end repeat
There are several AppleScript resources, but the main ones I use are:
AppleScript Language Guide
AppleScript Tutorials at MacScripter.net
