Listing a join column only once in a select
Hi. Has there been any advancement in t-sql where I can continue to select * on tables a and b in a join but expect to get back only one occurrence of columns that r used in the join. Or do I still need to explicitly list all cols in the
query?
eg. select a.*,b.* from a inner join b on a.c = b.c
hoping there is some shorthand way to see c only once
Sorry, I would not refer your expectation with "advancement". Relational engine needs to identify each column separately in the query, user have capability to select required columns.
If you consider LEFT OUTER JOIN, how would it decide which column to display from LEFT or RIGHT table (because when the values do not match you will still have all the rows from LEFT table).
When you specify "*" it brings the entire result set. So you will have to do little work and select only the required column. :-)

WHEN-LIST-CHANGED Triggers Works Only Once ??
hi
i have a form with the 2 list ITEMS
And i have some trigger WHEN-LIST-CHANGED For the
first LIST item which Populates the Second List
Based on the Value selected in First List
Its Works Fine For the First time.
But for second time Onward , it Does change the Value of the items in List2.
Do i have to first clear and then repopulate, i tried this but then i get a total
Blank , please help.
jaiFrom one of our support notes:
List Items populated from Record Groups are extremely useful when you need to
give your users a choice of items to choose from. This note will show you how
to create two list items that have a "master-detail" relationship, i.e., the
items appearing in the "detail" list item will depend on what is chosen in the
"master" list item.
CREATING THE LIST ITEMS
Create two list items called DEPT_LIST and ENAME_LIST. Allow them to remain
the default type of List Item, Poplists. For this situation we will not make
them base table items. Go to the property pallet of each list item, click on
the elements in list property and choose more. The cursor should be in the
very topmost item under List_Elements. Depress CTRL+SHIFT+< to remove this
default element and depress the OK button. Since you are going to populate the
list item with RG values at runtime you do not need this element. This will
avoid an "FRM-30351: No list elements defined for list item" error when
running the form.
CREATING THE RECORD GROUPS
For this example, we will use the dept and emp tables. We have a choice of
creating the Record Groups (RG) dynamically at runtime or at design
time. In this case, the easiest option is to create them at design time.
First create a RG called DEPT_GROUP with the following select statement:
SELECT TO_CHAR(DEPTNO) A,TO_CHAR(DEPTNO) B
FROM DEPT
If you are unfamiliar with the structure of the RG required when it will be
used to populate a list item please note the following:
1. A list item has both a label and a value. For this reason the select
statement brings back two fields, one which will be the label name and the other
the label value.
2. TO_CHAR is used to convert numeric values to character as the list item
contains character values.
Second, create a RG called ENAME_GROUP with the following select statement:
SELECT ENAME A, ENAME B FROM EMP ORDER BY ENAME
Note that depending upon your applications logic you may want to use the
distinct operator to prevent duplicate names. But you should be aware that
this will result in the overhead for sorting. Also, since ENAME is a VARCHAR2
data type, the to_char function is not needed.
POPULATING THE GROUPS AND LIST ITEMS
You can populate the RGs and list items from a number of triggers but the most
common is the WHEN-NEW-FORM-INSTANCE trigger. Place the following code in this
trigger:
DECLARE
V_DEPT_GROUP NUMBER;
V_ENAME_GROUP NUMBER;
BEGIN
V_DEPT_GROUP:=POPULATE_GROUP('DEPT_GROUP');
V_ENAME_GROUP:=POPULATE_GROUP('ENAME_GROUP');
POPULATE_LIST('DEPT_LIST','DEPT_GROUP');
POPULATE_LIST('ENAME_LIST','ENAME_GROUP');
END;
Note that this code is needed to initially populate both RGs and both List
Items.
If you run the form at this time you will see that DEPT_LIST contains all the
departments in Dept and ENAME_LIST contains ALL the enames in the emp table.
As our original goal was to populate ENAME_LIST depending upon what was chosen
from DEPT_LIST, we will now add the code to do this. In this situation we will
add the code to a WHEN-LIST-CHANGED trigger on DEPT_LIST. The code should
look as follows:
DECLARE
V_NUMBER NUMBER;
V_QUERY VARCHAR2(512);
BEGIN
V_QUERY:='SELECT ENAME A, ENAME B FROM EMP
WHERE DEPTNO = '||:DEPT_LIST||' ORDER BY ENAME';
V_NUMBER:=POPULATE_GROUP_WITH_QUERY('ENAME_GROUP',V_QUERY);
POPULATE_LIST('ENAME_LIST','ENAME_GROUP');
END;
First we will build a query that will contain the currently chosen department
in DEPT_LIST. This is basically the same query we created in RG ENAME_GROUP
but we are adding the where clause restriction. We then use the
populate_group_with_query built-in to repopulate the RG and then populate the
list again.
Run the form again and test. Choose department 10 from the DEPT_LIST list item
and then choose the ENAME_LIST item. You will note that the enames appearing
in ENAME_LIST will be those in department 10. This should work for any
department you choose. -

Should columns only be read once....
Good day,
I have a question about reading the resultset.
I was recently reading the java.sql API.
And in the description for the Resultset interface.
It mentions that "each column should be read only once"
Currently I don't call columns via results.getString("column") directly.
I usually set it to a variable and the use the variable as much as i need.
This method mainly helps me keep organized.
I was wondering if there are any real problems or issues that may arise from calling a column directly a numerous amount of times.
I don't plan on chaning my current method of going about resultsets, but i was just curious.
thanks,
alexHi,
You can scroll through the result set and read a column any number of time (provided proper resultSetType is set during statement creation).
see the scenario where such things will not work (but depends on the driver implementation). suppose u are retrieving rows in bulk (say >10k number of rows of large size).retrieving the bulk will give u out of memory etc exceptions. and if u set the fetchsize(int size)method things will become ok. but here u cant gurantee that u will get the column value on ur second visit to the same column (ie calling rs.getXX()method second time) .
so the rule thumb is retrieve the column value only once and store it in a variable- this is what u are doing rt now (if its a large value, process it on the spot according to ur need)

Display column titles only once per page
Hello,
I am a newbie to BIP (R12.1.3). Below is how the output data shows up in my custom template:
Vendor type lookup : Expense
Vendor no: A12345 Vendor Name: Test Vendor1 Vendor Category: Expense - Construction
VENDOR SITE INVOICE# INVOICE DATE DUE DATE INVCT AMT REM AMT PAYMENT METHOD
======== ====== ========= ====== ====== ====== ============
Kannapolis A#12345 03-MAR-12 15-MAR-12 1000.00 1000.00 Check
Vendor no: B12345 Vendor Name: Test Vendor2 Vendor Category: Expense - Rents
VENDOR SITE INVOICE# INVOICE DATE DUE DATE INVCT AMT REM AMT PAYMENT METHOD
======== ====== ========= ====== ====== ====== ============
Test Site B#12345 03-MAR-12 15-MAR-12 1500.00 1500.00 EFT
The column titles repeat for each vendor since the titles are in the for-each loop under the vendor grouping. However, is there a way to restrict the titles to show up only once per page on all the pages? I tried putting the titles outside the vendor grouping but with in the vendor type lookup grouping. It is displaying the titles only on page1.
Thanks,
MonkeyHi, could you try Inserting the code <?if:position()=1?> before the header of your template and the code <?end if?> after the header of your template.
See the a sample code below:
<?if:position()=1?>
VENDOR SITE INVOICE# INVOICE DATE DUE DATE INVCT AMT REM AMT PAYMENT METHOD
<?end if?>

Return each value only once using cfloop query
Hi,
I have some code that dynamically populates a cfselect list and then populates a second list based on those values. Everything seems to be working fine, except that all values are being pulled from the database, and there are duplicates in most cases. For example, value 1S1W diplays in the drop-down menu 10 times, where I would only like it there once.
Is there a way to have one of each value in my list?

</cfoutput>Emily,
OK. Yes it is possible. Change your first query to:
SELECT DISTINCT TOWNSHIP_RANGE
FROM slco_sire.dbo.area_reference_plats_doc INNER JOIN slco_sire.dbo.area_reference_plats_page
ON slco_sire.dbo.area_reference_plats_doc.doc_id = slco_sire.dbo.area_reference_plats_page.doc_id
ORDER BY TOWNSHIP_RANGE
</CFQUERY>
Notice I removed any mention of SECTION, because it's irrelevant to generating a unique list of TOWNSHIP_RANGE. Also, GROUP BY is not needed, but an ORDER BY will sort the records in alphanumeric order.
Then you need to modify your code where you generate the option list for the first pulldown:
<option value="#get_Main_Group.TOWNSHIP_RANGE#" <cfif StrucKeyExists(form,'select_Main_Group') AND form.select_Main_Group eq "#get_Main_Group.TOWNSHIP_RANGE#">selected</cfif>>#get_Main_Group.TOWNSHIP_RANGE#</option>
Here I did a couple of things beside changing SECTION references to TOWNSHIP_RANGE . It's a good idea to add the query name prefix to column names when you output them so that you avoid collisions with variables that have the same name. I also reduced your <CFIF> statements to one compound statement for simplicity, and replaced the IsDefined with a StructKeyExists function. This is considered to be better practice and won't throw an error when used in a compound statement (if you kept the IsDefined statement and tried that in a compound selection, it can sometimes throw errors if the variable in the IsDefined doesn't exist).
Now, your second query should be something like:
<cfquery name="get_Sub_Group" datasource="ds" dbtype="odbc">
SELECT DISTINCT SECTION
FROM slco_sire.dbo.area_reference_plats_doc INNER JOIN slco_sire.dbo.area_reference_plats_page
ON slco_sire.dbo.area_reference_plats_doc.doc_id = slco_sire.dbo.area_reference_plats_page.doc_id
WHERE TOWNSHIP_RANGE = '#page.select_Main_Group#'
ORDER BY SECTION
</cfquery>
Here I changed the WHERE clause to filter based on the TOWNSHIP_RANGE you selected in the first pull-down. This should now return a list of SECTIONs that match the TOWNSHIP_RANGE selected in the first pull-down.
Lastly, some minor changes to the option list for the second pulldown:
<option value="#get_Sub_Group.SECTION#">#get_Sub_Group.SECTION#</option>
One other thing I noticed. If you are on ColdFusion 8 or 9, the dbytpe="odbc" is no longer needed. I'm assuming you are using an ODBC database connection to something like MS Access. If so, you can omit the dbytype entirely. It's only needed now if you do query-of-query queries, where it would be dbtype="query".

Power Query: Expand multiple lists within a row at once
I have a json file that I've been fairly successful importing into excel using power query. My issue now is dealing with lists in multiple columns. I need to figure out how to expand the values of the lists at once so I only add rows once, versus multiple
times.
Example:
Row 1 - Text | List1 {1,1,2,4} | List2 {A,B,B,D} | List3 {W,X,Z,Z}|
Row 2 - Text | List1 {1,1,2,4} | List2 {A,B,B,D} | List3 {W,X,Z,Z}|
Row 3 - Text | List1 {1,1,2,4} | List2 {A,B,B,D} | List3 {W,X,Z,Z}|
When I use Table.ExpandListColumn on the first column (List1), it adds rows to the table. Row1 is expanded into four rows, which is fine but I can only do this one at a time resulting in too many rows being added. Row 1 is expanded as:
Text | 1 | List2 {A,B,B,D} | List3 {W,X,Z,Z}
Text | 1 | List2 {A,B,B,D} | List3 {W,X,Z,Z}
Text | 2 | List2 {A,B,B,D} | List3 {W,X,Z,Z}
Text | 4 | List2 {A,B,B,D} | List3 {W,X,Z,Z}
If you do this again for the next column (list2), it keeps adding rows. The above example should only have 12 rows. A single row needs to be expanded to look like:
Text | 1 | A | W
Text | 1 | B | X
Text | 2 | B | Z
Text | 4 | D | Z
Note, the lists will always be equal in size across a starting row but may be of larger or smaller sizes and can be null.You can account for nulls by testing to see if there is a list in the columns, but it would be cleaner to do this using a custom function e.g.
Create a custom function (query) called TableFromLists, The code would be:
(value1, value2, value3)=>
let
List1 = if Value.Is(value1, type {list}) then value1
else {value1},
List2 = if Value.Is(value2, type {list}) then value2
else {value2},
List3 = if Value.Is(value3, type {list}) then value3
else {value3},
Table = Table.FromColumns({List1,List2,List3})
in
Table
In the code, you test to see if each input value is a list. If so, then each identifier (List1...List3) is assigned the corresponding input value (value1...value3). If not, each identifier is assigned the input value converted to a list (by
surrounding the input value in braces).
Then, in the previous step 2, the formula for the custom column would be:
TableFromLists([List1],[List2],[List3]) -

What I actually trying to do is that I have a multiple tables and from these tables I'm going to write each of it into a flatfile that is a pipe delimeted that is why I have to make a loop to know how many fields I am going to write. The code that was attached are actually working, my only concern is that it will take a longer time of processing cause every record of a table it will pass to the for loop(checking how many column) wherein number of column/ were already known on the first loop.
Hi kajbj,
I think what your trying to explain is almost the same with below code which i had already tried. The problem with this is that the every loop of the outer loop data retrieve is only the data of the first record.
Statement sOutput = consrc.createStatement();
ResultSet sqlset4 = sOutput.executeQuery(xquery);
ResultSetMetaData rsMetaData = sqlset4.getMetaData();
int numberOfColumns = rsMetaData.getColumnCount();
String writefld = "";
while (sqlset4.next()) {
writefld = "";
if (sqlset4.isFirst()) {
for (int i = 1; i <= numberOfColumns; i++) {
if (xxformatid.equals("1") || xxformatid.equals("3")) {
writefld = writefld + "sqlset4.getString(" + i + ").trim()" + "|";
writefld = writefld.substring(0, writefld.length() - 1) ;
output.write("\r\n");
output.write(writefld);
output.close();
