SQL Date Function

Hi
I have problem regarding date function in the following statment and unable to sort out the real cause as yet, i am not finding any materail for using date function in sql where clause any one can help me why is it.
Sector Table
Sect_Id Varchar2(2),
Sect_name Varchar2(100),
Wef Date
:Adate--->Forms Field ,Datatype --->Char(11)
Trigger Post-Query <Block Level>
BEGIN
SELECT SECT_NAME INTO :SECTORNAME FROM SECTOR
WHERE SECT_ID=:SECTOR
AND TO_DATE(WEF,'MON-YYYY')=TO_DATE(:ADATE,'MON-YYYY');
EXCEPTION WHEN NO_DATA_FOUND THEN
MESSAGE ('DEFINE SECTOR SETUP...');
MESSAGE ('DEFINE SECTOR SETUP...');
END;
FRM-40735: POST-QUERY trigger raised unhandled exception ORA-01843.
Any help in this regard.
Thanks in advance

TO_DATE converts from a character string such as '2004-11-24' into an Oracle DATE. If you pass it an Oracle DATE, it first converts it to a character string using the default date format, then converts that back into a date. This is not only inefficient but unsafe, since the default date format can change, breaking your code.
TO_CHAR converts from various datatypes into a VARCHAR2 string. When converting from an Oracle DATE, it can provide the output in a variety of formats.
It's worth bookmarking the Oracle Documentation Library:
10g: download-west.oracle.com/docs/cd/B14117_01/nav/portal_3.htm
9i: otn.oracle.com/pls/db92/db92.docindex
TO_DATE(WEF,'DD-MON-YYYY')=TO_DATE(:ADATE,'YYYY-MM-DD');WEF is already a date. If you want to remove any time portion, use TRUNC(wef).

Help with Date function in sql query....

My question I guess is really 2...I'm trying to use the date function as a comparison in my WHERE clause in my sql command.
1. My date format is dd-MMM-yy eg. (01-Apr-06) ... my problem is the Apr is lower case where my field in the database is 01-APR-06 so when I compare 01-Apr-06 to 01-APR-06 is doesnt find any rows. Is there away that I can make the Apr all upper case so that it is APR.
2. My second problem is getting this "date" field to work in my sql stmt I keep getting errors and it works fine if I take my attempts at trying to compare the date.
--------------Date Code----------------------------------------------------------
<%!
String getFormattedDate(java.util.Date d)
SimpleDateFormat simpleDate = new SimpleDateFormat("01-MMM-yy");
return simpleDate.format(d);
%>
<%
java.util.Date d = new java.util.Date();
String dateString = getFormattedDate (d);
%>
---------------------------Sql statment------------------------------------------
ResultSet rset = stmt.executeQuery ("SELECT name " + " FROM table where rdate = '01-APR-06' order by name ");
Currently Im just hard coding the date but I need to make it so it uses the date code...so....
rdate should equal the date from the formatted date in upper case
something like
rdate = <%= dateString %>
Thanks in advance for any ideas anyone may have...

There are sql functions upper & lower.
SELECT name FROM table where upper(rdate) = '01-APR-06' order by name Or you could convert the date to a string, and use the toUpperCase & toLowerCase java.lang.String methods. It doesn't make much of a difference--do you want the java compiler to do the string conversion or the database?

Using a SQL data source and XML data source in the same template

I am trying to develop a template for the Request for Quote report generated in Apps 11.5.10. I have loaded the data from the XML output into the template, but I am missing one field - I need the org_id from the po_headers table. Is it possible to use a sql data source (i.e., "select org_id from po_headers_all where po_header_id = [insert header_id from xml data]...") in addition to the xml data source to populate the template at runtime? When you use the Insert > SQL functionality is it static at the time the template is created, or does it call to the database at runtime? I've looked through all the docs I could find, but this isn't clear.
Thanks for any help or suggestions you may have.
Rhonda

Hi Pablo
Thats a tough one ... if you go custom with a data template you will at least get support on the data template functionality ie you have a problem when you try and build one. You will not get support on the query inside the data template as you might have gotten with the Oracle Report, well you could at least log a bug against development for a bad query.
Eventually that Oracle Report will be converted by development anyway, theres an R12 project going on right now to switch the shipped OReports to data templates. AT this point you'll be fully supported again but:
1. You have to have R12 and
2. You'll need to wait for the patch
On reflection, if you are confident enough in the query then Oracle will support you on its implementation within a data template. Going forward you may be able to swap out your DT and out in the Oracle one without too much effort.

Data Federator Universe Date Functions

Hi,
I created a Data Federator Universe from target tables (Source Tables from: Sql Server 2005 and Oracle 10g). Now, I want to create a object in the universe: "Days between 2 dates"(coming from 2 different target tables). I don't see any other date functions other than CURDATE(). How to create my object?
Alternatively, Can I create a caliculated column in the existing target table? For Example, I want to create a new column "Days between 2 Dates" from 2 different tables by using a formula in Default mapping of the target table.
Thanks & Regards,
Peter

Hi Amit,
Thanks for your reply.
Ok. So, Universe on top of Data Federator has limited functionality.
And, other option you mentioned is on report level. I am creating an adhoc universe and I have few objects which will calculate days between 2 dates coming from 2 different tables.
But, how can I achieve this on Data Federator level. I have no function there to find Days Between 2 dates. I see lot of time and date functions but not the one I required. Also, I added a column in the target table and tried to apply the formula there in the default mapping area. But, I see only the selected target table. I need another date column from another table, which is not displayed in the default mapping area.
How can I achieve this?
Regards,
-Peter

Date Functions( first day of a month that is 3 months from now....)

I have recently written my first stored procedure.
Its rather a bunch of SQL statements.
I had to hard code lot of dates. most of them are first day of the current monthe or last day of current month etc.
I thot of parametrizing all the dates, but if a business person has to include all the parameters they could go wrong and get the wrong results.
Now, I want to use date functions to achieve these requirements:
Can any one please throw some insght into this:....
1) First day of current month,
2) last day of current month.
3) first day of previious month
4) last day of previous month
5) first day of a month that is 3 months from now.
6) last day of a month that is 3 months from now.
7).....
Can any one please throw some light on any one of this.. I can try to work from there onwards ....
Thanks a lot in advance,
Ac

Hi there,
1) First day of current month

SQL query, function or SP for converting varbinary to image(.jpg format).

Dear Sir/Mam
I want SQL query, function or SP which converts binary data to image (.jpg format).
I m able to convert image (.jpg format) to varbinary. But not able to convert vice versa.
thanks in advance.

Binary data is binary data - "image" is only an intrepretation of binary data. Therefore your question makes little sense in the context of sql server since it does not have any facilities to utilize images. Since you provide no context, I'm
guessing that you are trying to retrieve an image stored in the database in a varbinary column and have your application use it as an image. If so, you should post your question to a forum that is specific to your development environment.

Trunc date function not working correctly

Hi,
Another quick question if people don't mind. Bit confused about the trunc date function. I'm following the sql fundamentals exam guide and using their examples:
select trunc(to_date('02-jun-2009 13:00','dd-mon-yyyy hh24:mi')) day from dual;
this returns the 2nd of june, as it should, because, as far as i'm aware, leaving the optional variable out defaults the precision to 'day'. but when i explicitly add the variable 'day', as the guide has done with 'week' 'month' and 'year' in the following examples (so i assume this format is correct rather than dd/mon/yyyy), something goes wrong:
select trunc(to_date('02-jun-2009 13:00','dd-mon-yyyy' hh24:mi'), 'day') day from dual;
this returns the 31st of may. which is incorrect.
however replacing 'day' with 'dd' provides the correct answer of the 2nd again.
this isn't a major issue, it just bothers me that the guide seems (again) to be mistaken, something that is rapidly becoming a trend in their examples. i'd also quite like to know why this is happening, as it will help improve my understanding of sql in general - perhaps there is some sort of default to allow the correct use of the variable 'day' i'm overlooking and that the guide hasn't made clear.
btw, i'm working in sqlplus - although developer has some odd results too.
thanks alot,
nick

nick'day' doesn't trunc to the beginning of the day. It truncates to the first day of the week: in your case 31st May.
'ddd' truncates to the beginning of the day.
So, leaving the second parameter out defaults to 'ddd' not 'day'.

XLR Get Other Data Function

Hi all,
Im wondering if I can use cell valeu data in the Where clause of the GetOtherData function.
EG Get Invoice Key where Payment No = whatever is in cell D9.
I keep getting syntax errors.
I'm trying to report accross 2 modules - AR and Banking.
I need to display Invoice data as well as related payment data.
In report composer after making my AR selections, I try to drag and drop data from the Banking module to show payment data related to the Invoices.
The data is not retrieved.
I was wondering if this might be possible using the GetOtherData function in Advanced Report Builder.
Can I show data related to whats in a certain cell in my report?
Thanks for any suggestions.
John O'Brien

Hello,
In composer, you cannot use two modules together to get the information in each module.
Get other Data function can get the value in a specific field in tables. Please check online help file, there is detailed example about it.
the syntax in using Get Other Data is exactly same in SQL.

PL/SQL Pipelined Function to Compare *ANY* 2 tables

I am trying to create a pipelined function in 10g R1 that will take the name of two tables, compare the the tables using dynamic SQL and pipe out the resulting rows using the appropriate row type. The pipelined function will be used in a DML insert statement.
For example:
create table a (f1 number, f2, date, f3 varchar2);
create table b (f1 number, f2, date, f3 varchar2);
create table c (f1 number, f2, date, f3 varchar2);
create or replace TYPE AnyCollTyp IS TABLE OF ANYTYPE;
create or replace TYPE CRowType IS c%ROWTYPE;
create or replace TYPE CRowTabType IS table of CRowType;
CREATE OR REPLACE FUNCTION compareTables (p_source IN VARCHAR2, p_dest IN VARCHAR2)
RETURN AnyCollTyp PIPELINED
IS
CURSOR columnCur (p_tableName IN user_tab_columns.table_name%TYPE)
IS
SELECT column_name, column_id
FROM user_tab_columns
WHERE table_name = p_tableName
ORDER BY column_id;
l_cur sys_refcursor;
l_rec ANYTYPE;
l_stmt VARCHAR2 (32767);
BEGIN
l_stmt := 'select ';
FOR columnRec IN columnCur (p_dest)
LOOP
l_stmt := l_stmt || CASE
WHEN columnRec.column_id > 1
THEN ','
ELSE ''
END || columnRec.column_name;
END LOOP;
l_stmt := l_stmt || ' from ' || p_source;
l_stmt := l_stmt || ' minus ';
l_stmt := l_stmt || ' select ';
FOR columnRec IN columnCur (p_dest)
LOOP
l_stmt := l_stmt || CASE
WHEN columnRec.column_id > 1
THEN ','
ELSE ''
END || columnRec.column_name;
END LOOP;
l_stmt := l_stmt || ' from ' || p_dest;
OPEN l_cur FOR l_stmt;
LOOP
FETCH l_cur
INTO l_rec;
PIPE ROW (l_rec);
EXIT WHEN l_cur%NOTFOUND;
END LOOP;
CLOSE l_cur;
RETURN;
END compareTables;
The pipelined function gets created without error. However, the testCompare procedure gets an error:
SQL> create or replace procedure testCompare is
begin
insert into c
select *
from (TABLE(CAST(compareTables('a','b') as cRowTabType)));
dbms_output.put_line(SQL%ROWCOUNT || ' rows inserted into c.');
end;
Warning: Procedure created with compilation errors.
SQL> show errors
Errors for PROCEDURE TESTCOMPARE:

3/4 PL/SQL: SQL Statement ignored
5/47 PL/SQL: ORA-22800: invalid user-defined type
Does anyone know what I am doing wrong? Is there a better way to compare any two tables and get the resulting rows?

I am getting a "Expression is not valid for this DBMS error" with the details as getcertdate is not a recognized built in function name. Please help on fixing this issue.
