Nested query loops

If you have nested query loops (<cfloop
query="qA"><cfloop query="qB"> qA vars in here
</cfloop></cfloop>), is it possible to carry the vars
from qA into the qB loop.
Not sure if this makes sense, but any time i have nested
query loops, i can't access the outer loops vars.

Use a different index variable for each loop. Use complete
syntax, ie queryname.fieldname[rownumber] for each query
variable.

Nested Query Loop

I have a query that I want to loop over the data and display.
The query is an inner join with one table being order numbers and
the second being details on each order. They are joined by the
order number. What i am trying to do is loop over the data and
group all the details under the order number. I have tried numerous
nesting configurations and I have had no luck. This is what I would
like to see.
Order Number 1
Item 1
Item 2
Item 3
Order Number 2
Item 1
Item 2
Order Number 3
item 1
Item 2
Item 3
Item 4
Any recomendations?

You could use the "group" attribute of cfoutput. In your sql
query, sort the results by the [OrderNumber] column. Then group by
[OrderNumber] in your output.
<cfoutput query="yourQuery" group="OrderNumber">

#OrderNumber# 
<cfoutput>
#ItemNumber#
<cfoutput>
</cfoutput>

How to do a Nested Query ?

I have three Tables Student, Courses, Marks
Table : Student
Columns
StudentID <PK>
First Name
Last Name
Table : Grades
Columns
StudentID <FK>
Grade
Table : Courses
Columns
StudentID <FK>
CourseID
CourseDesc
Now to get all the course descriptions which this particular student is taking based on the StudentID we do something like this :
SELECT c.courseDesc
FROM Courses c, Student s
WHERE s.StudentID = '100'
AND s.StudentID = c.StudentID
The above will work
But If I need to do it in nested query how can I do it : Something like
SELECT * FROM
SELECT c.courseDesc
FROM Courses c, Student s
AND s.StudentID = c.StudentID
WHERE s.StudentID = '100'
Thanks for the help.

oops,try this...
SELECT * FROM (
SELECT s.StudentID,c.courseDesc
FROM Courses c, Student s
WHERE s.StudentID = c.StudentID)
WHERE StudentID = '100';
SQL> select * from

Issues with nested for loops - saving images from a camera

Hi all,
I've written a vi. to capture a specific number of images ('Image No') and save these images, outputted to a folder of my choice. Each image is identified sequentially. However, I wish to do a number of iterations ('Run') of this capture sequence, such that the filename of each image would be 'Filename (Run)_(Image No).png', e.g. run 5, image 10 would be 'Filename 5_10.png'. I have tried a nested for loop for this but I receive an error 'Asynchronous I/O operation in progress' (I've attached a printscreen).
Can anyone assist me in solving this problem? I preiously posted this in machine Vision but got no response (http://forums.ni.com/t5/Machine-Vision/Capturing-image-sequences-issues-with-nested-for-loops/m-p/19...). Please find attached my vi.
Kindest regards and thanks,

Miika,
the problem is not the filenam, but the name of the folder (AHHHHH!). You try to create the same folder in the outer for loop over and over again.... (it is the error message above the '======', not below )

Nested for loop in Xquery

hi all,
I need to implement nested for loop in Xquery, but not able to do. Please help.
Thanks in advance..
Rajan

Nested for loops are simple in Xquery. Here is a very basic example:
Input:
<root>
<FirstLevel>
 <SecondLevel>
 <Value>1</Value>
 </SecondLevel>
 <SecondLevel>
 <Value>2</Value>
 </SecondLevel>
 <SecondLevel>
 <Value>3</Value>
 </SecondLevel>
</FirstLevel>
<FirstLevel>
 <SecondLevel>
 <Value>4</Value>
 </SecondLevel>
 <SecondLevel>
 <Value>5</Value>
 </SecondLevel>
 <SecondLevel>
 <Value>6</Value>
 </SecondLevel>
</FirstLevel>
</root>XQuery:
declare namespace ns0 = "http://temp.uri/OTM";
declare function ns0:NestedForLoop($input as element(*)) as element(*)
 <ns0:Output>
 for $firstLevel in $input/FirstLevel
 for $secondLevel in $firstLevel/SecondLevel
 return
 <element>{ $secondLevel/Value/text() }</element>
 </ns0:Output>
declare variable $input aselement(*) external;
ns0:NestedForLoop($input)Output:
<otm:Output xmlns:otm="http://temp.uri/OTM">
 <element>1</element>
 <element>2</element>
 <element>3</element>
 <element>4</element>
 <element>5</element>
 <element>6</element>
</otm:Output>Of course, this case is very simple and usually you wont even loop for this you can use a simple XPath like $input/FirstLevel/SecondLevel/Value/text() to achieve the above result. So, If you are having problems in a specific case of nested for loops, please post the input and output here and we can help out.

Using nested query to avoid repeated object traversal

Hi everyone,
My SQL is still very basic, hopefully this is not a dumb question ;-)
I have a table with a single spatial column of type SDO_GEOMETRY:
SQL> desc WITHIN_POINT_DISTANCE_TAB
Name                                            Null?    Type
POINT                                                    MDSYS.SDO_GEOMETRYin which I store only single point geometries. I discovered that using the min/max SQL operators to get the combined extend of my points is faster than using SDO_TUNE.EXTEND_OF:
SQL> select min(e.point.sdo_point.x) min_x, max(e.point.sdo_point.x) max_x, min(e.point.sdo_point.y) min_y, max(e.point.
sdo_point.y) max_y from WITHIN_POINT_DISTANCE_TAB e;
     MIN_X      MAX_X      MIN_Y      MAX_Y
-44.700001 737.400024 -23.870001 1094.83008
Elapsed: 00:00:00.01but it bothers me a bit to repeat e.point.sdo_point 4 times in the above (what can I say, I'm a developer ;-) So I thought I could use a nested query to select all the SDO_POINT_TYPE sdo_point's and refer it using a p alias, and be able to simplify the query to:
SQL> select min(p.x), min(p.y), max(p.x), max(p.y) from (select t.point.sdo_point from WITHIN_POINT_DISTANCE_TAB t) p;
select min(p.x), min(p.y), max(p.x), max(p.y) from (select t.point.sdo_point from WITHIN_POINT_DISTANCE_TAB t) p
ERROR at line 1:
ORA-00904: "P"."Y": invalid identifierBut obviously this is incorrect, yet I'd like to understand what I'm missing here.
I posited that maybe the sub-query can't return an object member and needs to return a column, but that doesn't appear to be the case:
SQL> select min(p.sdo_point.x), min(p.sdo_point.y), max(p.sdo_point.x), max(p.sdo_point.y) from (select t.point from WIT
HIN_POINT_DISTANCE_TAB t) p;
select min(p.sdo_point.x), min(p.sdo_point.y), max(p.sdo_point.x), max(p.sdo_point.y) from (select t.point from WITHIN_P
OINT_DISTANCE_TAB t) p
ERROR at line 1:
ORA-00904: "P"."SDO_POINT"."Y": invalid identifierCan someone please explain why the nested query approach fails as written above?
More generally, is it a bad idea to go for a nested query just for syntactic reasons? Are there performance implications going the nested query route above? (I actually wanted to see the perf. implications experimentally, but since it fails I can't...)
Any insight would be appreciated. Thanks, --DD

Thank you Peter. I now understand that I need to alias the column in addition to the table (the latter only because I traverse objects which require table aliases).
SQL> select min(t.p.x), min(t.p.y), max(t.p.x), max(t.p.y) from
2 (select nt.point.sdo_point p from WITHIN_POINT_DISTANCE_TAB nt) t;
MIN(T.P.X) MIN(T.P.Y) MAX(T.P.X) MAX(T.P.Y)
-44.700001 -23.870001 737.400024 1094.83008
Elapsed: 00:00:00.01Performance-wise it looks similar, but I need to test on a bigger table because it's too fast with 10K points to show differences. Overall it doesn't look that using the nested query syntax makes the query more readable once all pieces to make it work are there.
Thanks again, --DD
PS: Just aliasing the column and not the outer table fails:
SQL> select min(p.x), min(p.y), max(p.x), max(p.y) from (select nt.point.sdo_point p from WITHIN_POINT_DISTANCE_TAB nt);
select min(p.x), min(p.y), max(p.x), max(p.y) from (select nt.point.sdo_point p from WITHIN_POINT_DISTANCE_TAB nt)

Count(*) with nested query

Hi,
I have a question about the count(*) with nested query.
I have a table T1 with these columns:
C1 number
C2 number
C3 number
C4 number
C5 number
(The type of each column is not relevant for the example.)
This query:
select C1, C2, C3, C4
from T1
group by C1, C2
it's not correct becausa C3 and C4 are not columns specified in the GROUP BY expression.
If if run this query:
select count(*)
from (select C1, C2, C3, C4
from T1
group by C1, C2)
I haven't an error message (the result is correctly the number of records).
Why?
Thanks.
Best regards,
Luca

Because you are just selecting count(*) and none of the columns from the subquery, Oracle is optimising it by ignoring the selected columns and just running the sub query with the group by columns. I know it seems odd, but if you take a basic example:
SQL> ed
Wrote file afiedt.buf
1 select count(*)
2 from (select empno, sal, mgr, deptno
3 from emp
4* group by deptno)
SQL> /
COUNT(*)
3... all columns but deptno are ignored
... but if you include one of the other columns, even if you group by that column...
SQL> ed
Wrote file afiedt.buf
1 select count(*), empno
2 from (select empno, sal, mgr, deptno
3 from emp
4 group by deptno)
5* group by empno
SQL> /
group by empno
ERROR at line 5:
ORA-00979: not a GROUP BY expression
SQL>... the error returns, because you're forcing oracle to include the column in the subquery.

Error in making left outer join to a nested query

i am writing this query getting error here i am using nested query with that i am making join it is giving error

i am using left outer join at virtual table say x your gave me its equivalent
EXISTS (SELECT 1 FROM IvItemGenericLink G
WHERE G.ITEMID =V.ID
AND G.GenericId = L.GenericId)-----its i guess inner join
i am not confirmed that why iam asking this i guess i have to use this
as i use keyword inner join for inner join and for left join i use
left outer join
EXISTS (SELECT 1 FROM IvItemGenericLink G
WHERE G.ITEMID =V.ID
AND G.GenericId(+) = L.GenericId)-----its i guess left outer join
left outer join

please tell me this in this regard

Nested For Loop Trouble?

Ok I need to have a nested for loop that asks a user to enter in a int number from 1-50. Whatever the number is, lets say 4 I need the program to count up asterisk and count down asterisks, like this.
This is my code:
import java.io.*;
public class Stars {
 static int n;
 static private InputStreamReader in = new InputStreamReader(System.in);
 static private BufferedReader br = new BufferedReader(in);
 public static void main(String[] Args)throws IOException
 System.out.println("Please enter in a number to see display: ");
 String num = br.readLine();
 n=Integer.parseInt(num);
 for(int i=1;i<=n;i++)
 for(int j=1;j<=i;j++)
 System.out.print("*");
 for(int j=1;j<=i;j--)
 System.out.print("*");
 System.out.println();
Can someone tell me what I am doing wrong so I can figure out my mistake(s).

Ok, well I know that the loop relies on the number entered in by the user. So if i pick 3 the three enter in the loop and counts up in a for loop and for every number it counts up to the three it does a print("*"); Now what I am getting confused about is where the other for loop comes into play. I know that I need to start from the number I have which is 3, so I need to have one less than that and then count down. The thing is that i'm not sure where or how the second for loop gets implemented into the code. Does it get nested with the first loop like this:
for(int i=1;i<=n;i++)
 for(int j=1;j<=i;j++)
 for(int j=n-1;j>=i;j--)
 System.out.print("*");
 System.out.println();
 }Or is the second for loop on its own like this:
for(int i=1;i<=n;i++)
 for(int j=1;j<=i;j++)
 System.out.print("*");
 for(int j=n-1;j>=i;j--)
 System.out.print("*");
 System.out.println();
 }If someone can help me understand, for this is my first time with nested for loops.

Interrupting Nested For Loops/Sequences

I have a lagre program consisting of nested for loops and case statements calibrating an array of patch antennas. The entire process of which will take about 15 hours. During this time, I want to have two things happen.
Every 20 minuites or so, I want the process to stop what it's doing, follow certain commands for the measurement equipment to recalibrate itself, and then go back to what it was doing.
I also want to protect it against unpredicted and predicted crashes. If the system needs to stop for whatever reason, I would like to be able to pick up the process where it left off. A sort of checkpoint system, where, when it passes a checkpoint, if it needs to be restarted, I can tell it to start from the last checkpoint it passed.
Anyone had any experiece with these types of problems?

Could you open and append parameters to a file? Every time you restart execution of the vi after crashes you can look through the contents of the file to determine the last operation that was successful and continue with the last know good settings. -SS

Multiplication Table with Two Nested For Loops

I am trying to code a multiplication table in which the user enters the number of rows between 2 and 10 and enters the number of columns from 2 to 10. This must be in nested for loop format somewhat like this:
rows has been assigned the input variable for rows and columns is the name for input value for columns
for (int i = 1; i <=rows; i++)
for (int j = 1; j <=columns; j++)
i * j
i can't figure out how to get it to print out in table format or if the calculation coding is correct. can anyone help me please?
it should look like this for rows is 4 and columns is 7
1 2 3 4 5 6 7
2 4 6 8 10 12 14
3 6 9 12 15 18 21
4 8 12 16 20 24 28

Nested for loops

Sorry to bother you all, but I have a small problem with my java homework.
I have to make a nested for loop to produce the following output:
00
10 11
20 21 22
30 31 32 33
(only goes from 0 to 3)
Now, all I have managed to do are two simple loops, one with increment 10 and the other with increment just ++.
Could you help me?

Think through this logically. You need two loops. You need this output:
00
10 11
20 21 22
30 31 32 33
Each number above has two digits (two digits, two loops...not a coincidence). So you need one loop to control the first digit, and another loop to control the second digit. Look at the values for the first digit: 0,1,2,3. Those are your first loop values. Now, each time the first loop has a value, your second loop goes through all of its values. Here's the values you need:
First iteration:
loop index 1: 0
loop index 2: 0
Second iteration:
loop index 1: 1
loop index 2: 0,1
Third Iteration:
loop index 1: 2
loop index 2: 0,1,2
Fourth Iteration:
loop index 1: 3
loop index 2: 0,1,2,3
Notice the pattern for loop 2? Look at the starting value for each iteration, and notice the ending value. That gives you your loop constraints.

Parsing is totally wrong. You function processXML() should be like that:
function processXML(e:Event):void
 slideData = new Array();
 loader.removeEventListener(Event.COMPLETE, processXML);
 loader.removeEventListener(IOErrorEvent.IO_ERROR, loadError);
 myXML = new XML(e.target.data);
 voiceOver = myXML.@voice_over;
 startOffset = myXML.@start_offset;
 myXML_Container_Length = myXML.children().length();
 var node:XMLList;
 for (var j:Number = 0; j <= myXML_Container_Length - 1; j++)
 id_cont_array.push(myXML.containerss[j].@id);
 node = myXML.containerss[j].children();
 myXML_textField_Length = node.length();
 for (var k:Number = 0; k <= myXML_textField_Length - 1; k++)
 switch (node[k].name().toString())
 case "textfield":
 trace(node[k].@id);
 id_textfield_array.push(node[k].@id);
 break;
 case "image":
 id_image_array.push(node.@id);
 break;

Capturing image sequences - issues with nested for loops

Hi all,
I've written a vi. to capture a specific number of images ('Image No') and save these images, outputted to a folder of my choice. Each image is identified sequentially. However, I wish to do a number of iterations ('Run') of this capture sequence, such that the filename of each image would be 'Filename (Run)_(Image No).png', e.g. run 5, image 10 would be 'Filename 5_10.png'. I have tried a nested for loop for this but I receive an error 'Asynchronous I/O operation in progress' (I've attached a printscreen).
Can anyone assist me in solving this problem? Please find attached my vi.
Kindest regards and thanks,
Miika

Hi,
You cannot create a folder if this one is already existing.
Just check that the folder exists before creating it.
