If so this may be useful

Update all rows in a View Column via one Apex Form field

Appreciate any helpful answers to this query.
I have an Apex App (4.x) where I have a view: PRICE_MODEL_CRA_V
In the view, I have the following applicable columns:
COUNTRY
GRADE
SALARY
In the form I have the following fields
:P16_COUNTRY (DROPDOWN)
:P16_GRADE (DROPDOWN)
:P16_SALARY (Number)
In my app, I have a form with an Update button. I am simply trying to get Apex to update all rows in the salaray column in the view, where the country and grade match.
I've the following code for the Update button:
UPDATE PRICE_MODEL_CRA_V
SET SALARY = :P16_SALARY
WHERE COUNTRY = :P16_COUNTRY
AND GRADE = :P16_GRADE
The option I have chosen in condition type is:
Value of Item / Column expression is NOT Null (as there are values in the column)
Also tried SQL Expression and it does not like..says that there is No Expression.
Thanks again if anyone can help :)

Hi,
Sorry I realize now that piece of information was not well supported.
If I choose SQL Expression for Condition Type in my Form Page and I try to Apply Changes
Apex says this..
•Failed to parse SQL query!
ORA-00936: missing expression
I was assuming that I need to have the colon for the items in the form where I am wanting Apex to grab the values entered by the user. I tried them without the colons with the SQL Expression condition and same result.
UPDATE PRICE_MODEL_CRA_V
SET SALARY = P16_SALARY
WHERE COUNTRY = P16_COUNTRY
AND GRADE = P16_GRADE
I did put 1-1/0 in my expression field and applied changes and then tried ot submit the form and it does not produce an error, so perhaps it is not being called? Where would I start with troubleshooting that?
Thanks,

Is it possible to Lock just one column value in a row?

Is it possible to Lock just one column value in a row
A Java Developer has just asked me if it is possible to Lock just one column value in a row in Oracle
select ename from emp where empno=7369 for update;
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
7369 SMITH CLERK 7902 17-DEC-80 800 20
will lock the entire row with empno=7369.
But is it possible to lock one column value from this row, like SAL=800 ?

Move row based on one duplicated value

is it possbile to move entire rows base on just the value in the first column?
1    a
1    b
2    c
2   d
the result should be
1   a
2   c

Yes - double the header row, then use a formula like the one that I posted but start in row 1, with the formula
=COUNTIF($A$1:$A1,$A1)
Then copy down, copy that column, paste as values, and finally, sort the entire table
based on that value. Then List1 will all have 1s in that column, List2 will have 2s, etc.

How to get one column value from a DOCUMENT TYPE attribute

Hi,
I have created a DOCUMENT TYPE attribute which queries from a table and all the column values( For Ex: Customer Name, Contact Name and Address) are displayed in the message body.
I want one column value(For Ex: Customer Name) to be displayed in the SUBJECT of the message.
How can this be done? Please let me know.
Thanks in advance.

Thanks Matt. I have used SETITEMATTRTEXT to get a single column value into an ITEM ATTRIBUTE.

===========================================================
I am using &ORG_NAME in the body and subject of my message. But the value is
not retrieved into the ITEM ATTRIBUTE when I run my process. It is just displaying in the message and the subject of hte message as "&ORG_NAME"
CUST_DATA_CHECK used in the resultout, is a function which returns 'T' or 'F'. That part is working fine. Just retrieving the ORG_NAME in the ITEM ATTRIBUTE is not working.
Am I going wrong somewhere? Please let me know.

How to retrieving latest row based on a column value

Hi,
Lets consider a scenario. I have a table which has a order number, count column which is our fact, a type column which contains types e.g. (A,B) with A has more priority then B. Now in our graph we are getting all rows i.e. if we have two rows in db for order #1 one for type A and one for type B, then it shows us data from both rows in graph.
But I need only to show one row of type A in this case as A has higher priority than B. The row with type B should not contribute in construction of my graph if type A for same row also exists.
I tried a solution, for which i created a new column at logical level which contain 1 for A and 0 for B. Now i put Max aggregation rule in it to get maximum value which will be row with Type A in our case. But it did not work.
How we will can achieve it in OBIEE?
Thanks.

if the resultant value above is less than 62, i do no want to display this entire row in the output. could you help me wout with this?

Counting rows based on a column value

Tricky Query.No offence if this is a repeat please.
This is a PROD issue in SYBASE.
TableA has id_flag_listing column
TableA
id_flag_listing
N
N
N
N
N
1) If all rows are set to 'N',then my count should be 0.
   PrimaryListing
   0
2) If there is one row which is 'Y' then this shoud be:
   id_flag_listing
   N
   N
   Y
   N
   N
   PrimaryListing
   1
How can I count in this manner?
Do i use decode? I am using
Select sum(decode(flg_active),'Y',1,0))
from TABLEA
Will the above work.??
I am using SQL for Sybase.
Please guide?

Did you even tried the SQL query I've given?
Your table A
SQL> SELECT flg_listing

11     UNION ALL
12     SELECT 'N' FROM DUAL
13 ) TABLEA;
FLG_LISTING

Your table A, from which I count where are of 'Y' value. In these queries, I change TableA contents.

Selecting rows based on one column change

Hi All -
I need to select the rows from a table (this table has 4 columns and has a primary key and have many records for that primary key).
I need to select all the rows for this primary key for which only one column (in this case "flag" column) has been changing from its past value.
How can I do this?
for example, table data is:
ID, flag, Profile,date
pk, Y, Profile4,01/10/10
pk, N, Profile4, 01/08/10
pk,N, Profile3, 01/07/10
pk,Y, Profile3, 01/05/10
pk,Y, Profile2, 01/03/10
pk,N, Profile1, 01/02/10
The output of the query I am looking for should return the following i.e. only retrieve rows whose previous flag value has been changed:
ID, flag, Profile,date
pk, Y, Profile4,01/10/10
pk,N, Profile3, 01/07/10
pk,Y, Profile2, 01/03/10
pk,N, Profile1, 01/02/10
Please share your expertise.
Thanks,

(3) Expected output: I want all the rows from this table where the flags have been changed from its previous value.That's a vague description. Post the exat output, like Solomon did:
ID F PROFILE DT
pk N Profile1 01/02/2010
pk Y Profile2 01/03/2010
pk N Profile3 01/07/2010
pk Y Profile4 01/10/2010
(4) I want all the rows from this table where the flags have been changed from its previous value.That's a repeat of the vague description. Explain how you get the crorrect results, with specific examples, like this:
"The row dated January 2 should be included, because it is the oldest row in the table, regardless of what its flag is.
The row dated January 3 should be included because ...
The row dated January 5 should *not* be included, because ..."
You don't have to explain every row, just every reason.
Solomon - I tried your query but the prev_flag is not being populated, it shows null value '-'NULL is not the same as '-'. Did you issue a command like
SET NULL "-"that would display a '-' instead of NULL?
Solomon's query works fine for me, as it did for him. Post your code, even if you just copied it from this site. (There may have been an editing problem.)
Frank - I tried your query, prev_flag is populated in this case but when I am using with the WITH clause, I am getting an error saying "unsupported column aliasing" , I guess WITH command doesnt allow use of column alias. The problem is that I forgot the keyword AS after the sub-query name.
WITH     got_prev_flag     AS
     SELECT     id, flag, profile, dt     -- DATE is not a good column name
     ,     LAG (flag, 1, '??') OVER (ORDER BY dt) AS prev_flag
     FROM     t
--     WHERE     ...     -- any filtering goes here
SELECT     id, flag, profile, dt
FROM     got_prev_flag
WHERE     flag     != prev_flag
;If you don't post data in an executable form, then people can't test their ideas. If people can't test their ideas, trivial mistakes like this are very likely.
This flag column will have either
Y or N columns. Could you tell me what is the use of "??" value.By default, LAG returns NULL for the first row. If you want to include the first row in the results, then "WHERE     flag     != prev_flag" won't work when prev_flag is NULL. We could explicitly check for "prev_flag IS NULL", but I find it cleared to override the default, and have LAG return '??' on the first row. I guessed that '??' would make the condition "WHERE     flag     != prev_flag" work, no matter what value flag had. There's nothing magical about '??'; you can use any string that will never actually match flag.

Dear Alll
I have a requirement to color the rows of a table based on a column value in it. I have tried and surfed many useful materials over the net. but none of them solves my purpose.

Display column values as a series/legend on a line chart where one column value can be more than one category

Hi Everyone
I don't know if this is possible or not, so I will describe it. I have a column in a table called Filing. There are currently three values in it ("Abuse", "Neglect", "Voluntary") and each record has this populated. I also have
the below slicer for the column also.
I would like to add a fourth value called "Abuse/Neglect" that would identify instances where both an Abuse and Neglect petition was filed, which is a subset of the Abuse and Neglect records in the Filing column.
My question is, is it possible to create a line chart that has the 4 Filing possibilities: "Abuse", "Neglect", "Voluntary", "Abuse/Neglect" as the Series/Legend in the line chart?
The problem is that there are records that are more than one category: Abuse or Neglect records can also be Abuse/Neglect.
Paul

Hi Paul,
According to your description, there is a column with the values ("Abuse", "Neglect", "Voluntary") in your table, now what you need to is that add another value "Abuse/Neglect" in this column, and then use it
as Series/Legend in the line chart, right?
In this case, you can add calculated column to your table based on your logic. A calculated column is a column that you add to an existing PowerPivot table. Instead of pasting or importing values in the column, you create a DAX formula that defines
the column values. The calculated column can be used in a PivotTable, PivotChart, or Power View report as you would any other data column. Please refer to the link below to see the details.

Resultset - retrieves all rows or only one at a time

Hey guys,
I am using oracle DB. Lets say the query i run has about 1000 records
when i call:
prepareStmt(cstmt);
Rsultset rs = cstmt.executeQuery();
Do I get all the records, or do i get them one by one
when i call
rs.next
is this DB specific??
This is simple q, but i been working with oracle and java for a while, and for some reason this never came up.
thank you.

The driver implementation is free to retrieve as many or as few rows at a time from the database as it wants. You can suggest to the driver how many rows at a time it should retrieve with setFetchSize(); the driver is free to ignore your suggestion (but many drivers honor it). The fetch size default varies wildly from driver to driver, from 1 row at a time to all rows at a once. For the Oracle thin driver, the default is 10, which is usually too small to give the best performance (I use between 100 and 1,000, usually 250).
Note that when you're working with a very large ResultSet, a driver that does "all rows at once" can cause you to run out of memory. Also, some drivers will cache every single row when using a scrollable ResultSet (and again run you out of memory) but not do so with a forward-only ResultSet (Oracle has this issue).

Replacing one column value between two rows..help??

HI,
I have table T
it has five columns, all are in number data type
Col1 and col2 are jointly primary key i.e. they cannot be repeated combined
when i run this query..
SQL> Select * from t
it shows me the data like this
Col1        Col2              Col3       Col4           Col5
1             1               78          58            12.76
2             1               128         446           32.10
3             1               468         566           52.10
4             1               878         58            52.05
5             1               987         348           22.02
... so on.
my requirement is that i want to update this table by replacing the col1 value between any two rows
suppose this is the first row
Col1        Col2          Col3        Col4         Col5
1             1             78          58        12.76
and this is any 2nd row
Col1        Col2          Col3        Col4        Col5
5             1            987         348       22.02
now i want that for first row the value of col1 replaces the value of col1 of 2nd row
and for 2nd row the value of col1 replaces the value of col1 of 1st row
i.e.
Col1        Col2          Col3        Col4         Col5
5             1            78           58         12.76
Col1        Col2          Col3        Col4         Col5
1             1            987        348          22.02
please tell how to achieve this in single query/procedureregards,
Ramis
