How to prepending a where clause column

Hello, Is there a way to accomplish prepending a '1' to a column in the where criteria? Of course this gives a query gives an invalid column error
select count(*)
FROM     ml_journals     a,
         ml_pay_headers_all b,
         emp_master           c
WHERE a.attribute6 = b.trans_id
and b.'1'||adp_employee_id = c.ps_empl_id;
I believe a LPAD function might do, correct?

yes, there is a way but you must (ab)use EXECUTE IMMEDIATE
SQL statements must be static & fixed at compile time

How can i work with getdate() in my query if i have a varchar datatype on where clause column ?

Hi All,
I have a column like lastdate with varchar datatype. now I want to work with lastdate column in where clause with getdate().
Ex: where
getdate() - lastdate < 1
when I use above one I got error like
Error = Conversion failed when converting date and/or
time from character string.
I knew the datatypes for lastdate and getdate() are different...
how can I use...
Thanks,
rup

You need to convert the string date to datetime or date. See conversion examples here:
http://www.sqlusa.com/bestpractices/datetimeconversion/
Example for the where clause:
WHERE DATEDIFF(DD, convert(datetime, lastdate, 101), getdate() ) < 1
Can you post sample string dates?
Are you looking for today's records? Another option (depends on lastdate format):
WHERE lastdate = convert(char(8), getdate(), 112)

How to set the where clause of a value set on the basis of a form field

I am using a DFF(Descriptive FlexField), which needs to display the value of a certain column(say columnA) on the basis of the value of another column(say columnB).
So i have created a value set which points to the table which has both these columns, and the DFF uses this value set. However, the problem is that I have not put any where clause in the value set, because of which i cannot handle the exact fetch returns more than one rows error.
The query has to be as follows:
select ColumnA from tbl where ColumnB = [ a form value ];
What I want to know is how can i get the value of a certain field of a certain block of the form in the above query.

Just have a look over these two statements if it solves your problem
one time where clause
Set_Block_Property('BLOCK_NAME',ONETIME_WHERE,your form item);
dynamic where clause
set_block_property('BLOCK_NAME'default_where, your form itme)
you can where clause at run time from any procedure or some triggers

How to modify the where clause in this to include other things

How do I modify the WHERE clause in this code:
$expected = array(first_name, last_name, level, language, 'city', 'state', 'zip', );
$query_search = 'SELECT * FROM french;
$where = false;
foreach ($expected as $var) {
if (isset($_GET[$var]) && !empty($_GET[$var])) {
if ($where) {
$query_search .= ' AND ';
} else {
$query_search .= ' WHERE ';
$where = true;
$query_search .= $var . ' = '. GetSQLValueString($_GET[$var], 'text');
to include things like searching multiple columns and IF NULL:
SELECT * from MyTable where (MyCol1 = %s or MyCol1 Is Null) AND (MyCol2 = %s or MyCol2 Is Null)
Where on earth does it go?

My goal is to have a search form and results combination that:
1) allows the user to ignore any of the page’s existing search fields that
they don’t need, (to search with empty form fields);
2) to use whichever search form fields they choose to use even if the
Registrant for whom they are searching did not insert that information when
they registered, (they are filled in the search form but empty in the
database table);
3) and to permit some of the seach fields to search multiple columns, for
example the search form field ‘sonsName’ would look for that information in
three different database table colums, (sonsName1, sonsName2 etc.).
You’ve given me code that permits 1) above to work beautifully. You’ve also
sent along code that should let me accomplish the other two, and though I’ve
been able to recreate below what I want the multiple search column to do, I
can get neither the multiple column nor the IS NULL sections to work in the
code you sent most recently.
How do I take something like this:
$colname_rsSearch = "-1";
if (isset($_POST['first_name_now'])) {
$colname_rsSearch = $_POST['first_name_now'];
$colname2_rsSearch = "-1";
if (isset($_POST['last_name_now'])) {
$colname2_rsSearch = $_POST['last_name_now'];
$colname3_rsSearch = "-1";
if (isset($_POST['sonsName'])) {
$colname3_rsSearch = $_POST['sonsName'];
mysql_select_db($database_connStr_Milo_db, $connStr_Milo_db);
$query_rsSearch = sprintf("SELECT milo.first_name_now, milo.last_name_now,
milo.ws_number, milo.ws_number_3, milo.ws_number_4 FROM milo WHERE
milo.first_name_now = %s AND milo.last_name_now = %s AND (milo.sonsName1 =
%s) || (milo.sonsName2 = %s) || (milo.sonsName3 = %s)",
GetSQLValueString($colname_rsSearch,
"text"),GetSQLValueString($colname2_rsSearch,
"text"),GetSQLValueString($colname3_rsSearch,
"text"),GetSQLValueString($colname3_rsSearch,
"text"),GetSQLValueString($colname3_rsSearch, "text"));
$rsSearch = mysql_query($query_rsSearch, $connStr_Milo_db) or
die(mysql_error());
$row_rsSearch = mysql_fetch_assoc($rsSearch);
$totalRows_rsSearch = mysql_num_rows($rsSearch);
?> (I’ve excluded the IS NULL part from my example, but need it in the final
version)
…and make it work using your code below (which permits someone to search
with empty form fields, but does not yet enlighten me on what to group (with
parenthesis) to make the code execute the multiple column search and the IS
NULL parts of the search.
mysql_select_db($database_connStr_Milo_db, $connStr_Milo_db);
$expected = array('first_name_now', 'last_name_now', sonsName'
$query_search = 'SELECT milo.first_name_now, milo.last_name_now,
milo.ws_number, milo.ws_number_3, milo.ws_number_4 FROM milo';
$where = false;
foreach ($expected as $var) {
if (isset($_POST[$var]) && !empty($_POST[$var])) {
    if ($where) {
      $query_search .= ' AND ';
    } else {
      $query_search .= ' WHERE ';
      $where = true;
$query_search .= '(' . $var . ' = '. GetSQLValueString($_POST[$var],
'text') .
' OR ' . $var . ' IS NULL)';
$search = mysql_query($query_search, $connStr_Milo_db) or
die(mysql_error());
$row_search = mysql_fetch_assoc($search);
$totalRows_search = mysql_num_rows($search);
As always, thank you.

How to establish a where clause dinamically in a form?

I've a form with a table activities that must call (with a custom button) to a form with (only) the documents associated to this activity.
In the BD i have the table Activities (pk=codi_acti), the table documents (pk=codi_docu) and one more table for associate both called activities_documents (pk=codi_acti, codi_docu).
The user editing the activity X after click the button must see all the documents of X but nothing else.
My first attempt was a MD Form with the table activities_documents as master and the table documents as detail, but documents have a blob column and then this is not possible.
Now I'm trying to establish the where clause to perform this but I can't get it. I pass codi_acti to this (documents) form and then I should show all the documents that have codi_docu in the table activities_documents, otherwise SELECT * FROM documents WHERE codi_docu IN (SELECT codi_docu FROM activities_documents WHERE codi_docu=:codi_acti).
How can I achieve this?
Please Help!!!
Sincerely
David Montejo

Forms can autoquery data based on the URL used to call the form. You can build the URL
and call the form with the required query, on successfull form submission you can do the following
begin
declare
my_url varchar2(2000);
n_rl_id number;
begin
n_rh_id:=p_session.get_value_as_NUMBER(
p_block_name => 'MASTER_BLOCK',
p_attribute_name => 'A_RH_ID',
p_index => 1
my_url := 'PORTAL30.wwa_app_module.link?' ||
'p_arg_names=_moduleid&p_arg_values=<your form id>' ||
'&p_arg_names=_show_header&p_arg_values=YES' ||
'&p_arg_names=rh_id&p_arg_values=' || LTRIM(TO_CHAR(n_rh_id)) ||
'&p_arg_names=_rh_id_cond&p_arg_values=%3D';
-- %3d means "="
go (my_url);
end;
end;

How to dynamically build where clause in Linq

Hello everyone,
Oracle DB:11gR2
Oracle Client: 11.2.0.3.0 (ODP.NET)
Oracle Developer Tools for Visual Studio
VS 2010 (C#)
In a Windows Form, we need to query the data based on the values of dropdown listboxes, which user will select.
Let's say, two combox, one is for Department and one is for Salary
Department:
-1 All
10 Department 1
20 Department 2
30 Department 3
Salary:
-1 All
1 < 20000
2 20000 to 50000
3 50000 to 100000
4 > 100000
Here is C# code to query data:
using (var myEDMctx = new HREntities())
var LINQrslt = from emp in myEDMctx.EMPLOYEES
select emp;
The default values for both combox should be All.
How to write the dynamic where clause for this LINQ?
Thanks in advance!!!

There is nothing Oracle-specific about dynamic LINQ queries. Dynamic LINQ queries are handled all the same way, no matter which data source you use. Microsoft describes how to use Dynamic LINQ here:

How to set dynamic where clause in ADF?

Hi,
I have a View object called BillInfoVO. This has
all the information about who created the request, the time , status etc.,
I need to display this VO in a jsp. But before I display, i need to fileter this
VO results with different where clauses according to the role of the user.
For example, if the role is admin, then
where clause should be 'status = 'Completed, and created by = 'Current user'
If the role is requestor, then
the where clause should be
sales manager id = 'Current user' and
Status != Complete etc.,
Could any one please let me know how I can
dynamically set the where clause to filter the appropirate
result row set in the jsp?
Your help will be greatly appreciated.
Thanks,
venki

You'll create a service method in your AM that will use the setWhereClause method of a viewobject.
Then you'll expose it as a client method.
Then you'll drag it from your data-control onto a button in your JSF page that will call your page for the query.
More about service methods here:

VPD - How to make the where clause a correlated query

Hi,
My VPD function has the following where clause:
where_clause:= ' project_id in (select object_id from pa_project_classes p'||
' where p.class_category='||''''||l_cat||''''||
' and p.CLASS_CODE='||''''||l_class||''''||
' and p.OBJECT_TYPE=''PA_PROJECTS'''||
The problem is that the subquery is not using the unique key defined on the table pa_project_classes. What I need is something as follows:
where_clause:= ' project_id in (select object_id from pa_project_classes p'||
' where p.class_category='||''''||l_cat||''''||
' and p.CLASS_CODE='||''''||l_class||''''||
' and p.OBJECT_TYPE=''PA_PROJECTS'''||
' and p.object_id=mainquery.project_id ||
The problem is that since the table pa_project_classes also has a column project_id, I have to prefix the column name by the alias of the main query like 'mainquery.project_id'. However this seems impossible as main query is not unknown .
I would be grateful if you could suggest any workaround or solution.
Thanks

Just have a look over these two statements if it solves your problem
one time where clause
Set_Block_Property('BLOCK_NAME',ONETIME_WHERE,your form item);
dynamic where clause
set_block_property('BLOCK_NAME'default_where, your form itme)
you can where clause at run time from any procedure or some triggers

How to filter rows where multiple columns meet criteria, ignoring rows where only some columns meet criteria

Hi All,
Question: How do I filter rows out of a query where multiple columns are equal to a single question mark character?
Background: I'm using SQL 2008 R2. Furthermore, the part of my brain that helps me create less-than-simple queries hasn't been working for the last 4 days, apparently, and now I need help.
We have about 4,000 rows in a table. This data set was generated from an exported report, and many of the rows in the detail table were not actual data rows but were simply "header" rows. For those table rows, most of the columns have
a single question mark as the value.
Some of the detail rows have one or more question mark values, too, so it's important that these rows don't get filtered out.
When I include criteria like "WHERE col1 <> '?' AND col2 <> '?' AND col3 <> '?' AND col4 <> '?'", all rows with a question mark value for even a single one of those columns get filtered out. How do I filter out rows
where all columns 1-4 contain a question mark value?
Thanks for your help,
Eric

I just tried to create to create a scenario for you. Please see ig you're looking for something like this.
Create table test_Question_mark
RecordID INT identity(1,1),
Col1 varchar(10),
Col2 varchar(10),
Col3 varchar(10),
Col4 varchar(10),
insert into test_Question_mark (Col1, Col2, Col3, col4) values ('?','?','?','?')
insert into test_Question_mark (Col1, Col2, Col3, col4) values ('?','??','?','?')
insert into test_Question_mark (Col1, Col2, Col3, col4) values ('?','??','??','?')
insert into test_Question_mark (Col1, Col2, Col3, col4) values ('??','??','??','??')
insert into test_Question_mark (Col1, Col2, Col3, col4) values ('?','?','?','?')
insert into test_Question_mark (Col1, Col2, Col3, col4) values ('??','test ??','??','??')
insert into test_Question_mark (Col1, Col2, Col3, col4) values ('??','test ?','??','??')
--drop table test_Questio_mark
select * from test_Question_mark
select * from test_Question_mark
WHERE
(CHARINDEX('?', Col1,1) > 0 AND CHARINDEX('?', Col1, CHARINDEX('?', Col1,1)+1) = 0) AND
(CHARINDEX('?', Col2) > 0 AND CHARINDEX('?', Col2, CHARINDEX('?', Col2,1)+1) = 0) AND
(CHARINDEX('?', Col3,1) > 0 AND CHARINDEX('?', Col3, CHARINDEX('?', Col3,1)+1) = 0) AND
(CHARINDEX('?', Col4,1) > 0 AND CHARINDEX('?', Col4, CHARINDEX('?', Col4,1)+1) = 0)
--drop table test_Questio_mark
I hope above solution will help.
Thanks!
Ashish.

How to control a WHERE CLAUSE

I am converting our BO Universe to OBIEE. There exist in the Universe an object which select COUNT(DISTINCT inventory_item_id) and has a WHERE CLAUSE that gives a date range.
Going to OBIEE, how can I apply this WHERE CLAUSE to the object only? I can't find a place where to set this up. What I found was the WHERE CLAUSE box in the content tab of the table source. I wouldn't like to place it here because this WHERE CLAUSE should only fire when this object is selected by the user in his report.
I would appreciate your help very much.
Thank you.

Hi,
I created a report filter instead and saved it. I noticed one thing when I tested this. It took a while for the report to be generated. Is there a way I could do improve on the performance? This is what I placed in the report filter:
CURRENT_DATE >= IFNULL("- Price List Lines"."Item Start Date" , CURRENT_DATE ) AND CURRENT_DATE < IFNULL("- Price List Lines"."Item End Date", TIMESTAMPADD( SQL_TSI_DAY , CURRENT_DATE , 1))
Thank you.

How to set dynamic WHERE clause to VO from backingBean?

Hi,
Can any one let me know the best way to add the dynamic WHERE clause in to VO query.
I have created AM (with AMImpl.java) & VO (with VOImpl.java & VORowImpl.java) in my model project. I suppose to set the WHERE condition at runtime while the user click the search button. I am handling the user button click at UI layer backingBean. From the backing bean I could able to get the objct of the VO and set the where clause by below code.
        ValueExpression valueExp = elFactory.createValueExpression(elContext, "#{bindings.UserSearchVO1Iterator}", Object.class);
        DCIteratorBinding dcIter = (DCIteratorBinding)valueExp.getValue(elContext);
        ViewObject userSearchVO = dcIter.getViewObject();
        userSearchVO.setWhereClause("lower(usr_login) LIKE ':1' and usr_udf_suid like ':2' ");
        userSearchVO.executeQuery();But as I fear this is not the right way to do it. So I am creating the cutom method inside the VOImpl.java and triggring that method by creating one more cutom method in AMImpl.java. But I dont know how to invoke this AM method from backingBean.
AMImpl method
public void initDetails()
        UserSearchVOImpl vo = getUserSearchVO1();
        vo.initQuery();
VOImpl method
    public void initQuery()
        setWhereClause("lower(usr_login) LIKE 'a%' and usr_udf_suid like '%1144%'");
        executeQuery();
    }Can any one guide me which is the best way to set the where clause to VO? How to call the AM method from backingBean?
Thanks

How to create dynamic where clause instead of pragmatically

Hi,
I'm using Jdev 11.1.2.2.0 and my requirement to create a two fields with search button to fetch data as adf table. User need to enter either of the field value and click search button to see his data.
So I created a sql query based view object with 2 bind variables (which are input params) & 2 view criteria (to create dynamically where clause) and then drag on to the page by ExecuteWithParams operation from data controls but couldnt work.
If anyone have idea to build dynamically please let me know.
Amar

User need to enter either of the field value and click search button to see his data.User need to enter either of the field value and click search button to see his data.
Hi Amar,
Is your requirement, creating a query panel with table??
Drag and drop the view criteria(Application Navigator>DataControls> AppModule >NamedCriteria> ViewCriteriaName ) onto the page.
In the context menu, select Query->ADFQueryPanel With Table.. That brings your necessary two columns and Search field with data represented as a table.

and code.code_name="transaction_1"In the first portion and
and code.code_name="transaction_2"So if that's all that is difference, you'd just want to use a single query (no union's) with
and code.code_name in ('transaction_1', 'transaction_2')Cheers,
