Dynamic query, where clause help

Hi Folks,
Using my code below to generate a query.
When using more than one condition, I'm not sure how to work out where the AND goes.
Can anyone please help?
Thankyou
WHERE
<cfif stafffilter neq "">
deviceofficer = #stafffilter#
</cfif>
<cfif assetid neq "">
AND deviceasset = '#assetid#'
</cfif>
<cfif isdefined("noasset")>
AND deviceasset = ''
</cfif>
<cfif isdefined("noserial")>
AND deviceserial = ''
</cfif>
<cfif serial neq "">
AND deviceserial = '#serial#'
</cfif>
<cfif servicearea neq "">
AND deviceservice = #servicearea#
</cfif>
ORDER by locationname

I do this sort of thing:
<cfset sWhereAnd = "WHERE">
<cfif isdefined("colFilter")>
     #sWhereAnd# col = #colFilter#
    <cfset sWhereAnd = "AND">
</cfif>
<cfif isdefined("someOtherColFilter")>
     #sWhereAnd# someOtherCol = #someOtherColFilter#
    <cfset sWhereAnd = "AND">
</cfif>
[etc]
(that's pseudocode... I'd never use isDefined() or not use a <cfqueryparam> tag for my parameter values).
I don't like doing the somewhat popular WHERE 1=1 approach as it can force a full table scan (all rows in the table will match that, and each WHERE filter expression is applied to every row of the table being filtered), unless the DB optimises it out as noise (which is what it is). To me it's using bad SQL to cut corners.
To be honest though, I shy away from these generic sort of queries these days. Most of the genericism never gets used, and more specific requirements are better implemented to meet the precise need.

Dynamic Query Where Clause

Hi,
I have the following query in a SQL Query (Pl/Sql Function Body Returning Sql Query) report:
DECLARE
q VARCHAR2(32767); -- query
w VARCHAR2(4000) ; -- where clause
we VARCHAR2(1) := 'N'; -- identifies if where clause exists
BEGIN
q:= 'SELECT "OSP_ID",' ||
' "OSP_NUMBER",'||
' "PROPOSAL_TITLE",'||
' "PROPOSAL_TYPE",'||
' "AGENCY_TYPE_CODE",'||
' "AGENCY_TYPE",'||
' "AGENCY_CODE",'||
' "AGENCY_NAME",'||
' "AGENCY_ABBREVIATION",'||
' "SPONSOR_CODE",'||
' "SPONSOR_NAME",'||
' "PI_NAME",'||
' "PI_EMP_NUMBER",'||
' "PI_PERS_ID" '||
' FROM "PROPOSAL_V" ';
IF :P25_OSP_NUMBER != '-All-'
THEN
w := ' OSP_NUMBER = :P25_OSP_NUMBER ';
we := 'Y';
END IF;
IF :P25_PROPOSAL_TYPE != '-1'
THEN
IF we = 'Y'
THEN
w := w || ' AND PROPOSAL_TYPE = :P25_PROPOSAL_TYPE ';
ELSE
w := ' PROPOSAL_TYPE = :P25_PROPOSAL_TYPE ';
we := 'Y';
END IF;
END IF;
IF we = 'Y'
THEN q := q || ' WHERE '|| w;
END IF;
RETURN q;
END;
What I need is to change the ' OSP_NUMBER = :P25_OSP_NUMBER ';
to ' OSP_NUMBER LIKE '%'||:P25_OSP_NUMBER'%'|| ';
But I'm getting errors when I do like above.
Can somebody please help...
Thanks in advance
- Pradeep

First of all, get rid of that silly "where exists" variable, just add a where clause like where 1=1 to the query and keep adding dynamic clauses with AND clause as needed.
Try
q := q||'and OSP_NUMBER LIKE ''%'''||:P25_OSP_NUMBER||'''%''';

Dynamic XQuery Where clause

I have the following schema:
<?xml version="1.0"?>
<xs:schema
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:tns="CountryRiskService"
targetNamespace="CountryRiskService"
elementFormDefault="qualified"
attributeFormDefault="unqualified">
<xs:element name="CountryRiskParameters">
<xs:complexType>
<xs:sequence>
<xs:element name="countryId" type="xs:int" minOccurs="1" maxOccurs="unbounded"/>
<xs:element name="catA" type="xs:boolean" minOccurs="0" maxOccurs="1"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
I am passing this into my Logical Data Service, what I want to do is create a dynamic XQuery where clause if the catA field is populated, ignore it if it isn’t, so basically, I want to be able to create a dynamic query based on the parameters requested, so I have the following XQUERY:
declare function tns:getCountries($countryRiskInput as element(ns7:CountryRiskParameters)) as element(ns0:CountryRiskInfo)* {
for $tbl_high_risk_countries in ns1:tbl_high_risk_countries()
where $countryRiskInput/ns4:countryId = $tbl_high_risk_countries/country_id
where $countryRiskInput/ns4:catA = $tbl_high_risk_countries/risk_catA
I really thought that DSP would be able to handle this on the fly since the element is optional but if I don’t populate it, I get nothing back, the idea is I want to increase the number of elements in my schema so my consumers have the ability to filter the results they want, so above, I don’t want the second where clause if catA isn't specified, any ideas how to accomplish this?

Simply add the disjunction of the input being empty.
for $tbl_high_risk_countries in ns1:tbl_high_risk_countries()
where $countryRiskInput/ns4:countryId = $tbl_high_risk_countries/country_id
where ( $countryRiskInput/ns4:catA = $tbl_high_risk_countries/risk_catA or empty( $countryRiskInput/ns4:catA )
But suppose you have 27 different elements that you might want to filter on - the xquery gets long and ugly. You might want to looking into using FilterXQuery. Visit http://edocs.bea.com/aldsp/docs25/, search on FilterXQuery, look for the tutorial.
If your queries get more complicated, you would do well to look into generating ad hoc queries. (edocs as well).

Change my sql query where-clause in an extended controller

Hello,
i am trying to change my sql query where-clause in an extended controller
personAplListVO.setWhereClause(null); // first set to null
personAplListVO.setWhereClauseParams(null); // first set to null
personAplListVO.setWhereClause(personAplListVOWhereClause +
newWhereClause);
personAplListVO.setWhereClauseParams(whereClauseParams);
personAplListVO.executeQuery();
System.out.println(">>>>>>>>getQuery = " + personAplListVO.getQuery());
when i get the query ( personAplListVO.getQuery()) after executeQuery(), the new newWhereClause values are missing.
Also i am getting null from personAplListVO.getWhereClause() after executeQuery()
as if the above code is not making any effect.
any ideas why?
Thank you

Adding filter conditions dynamically in WHERE clause -dynamic SQL help

Here I have a simple condition but very complicated query. Basically, I have to put a filter condition in my where clause. "Location" comes to the stored procedure as parameter. Plus there are other parameters as well.
If location = "all", I can run the query simply and get the result. But when Location = "CA", which is just a subset of "ALL" then I am having hard time putting one -- AND statement in WHERE clause.
This query is designed for location = 'ALL'
open cv for
'Select col1, col2, col3, Col4
from t1, t2, t3
WHERE condition1
AND condition2
AND condition3'
AND location = location_id --- This should only run if location IS NOT ALL
I have written a dynamic query but it doesn't work for that part. Any ideas will be appreciated. Thanks,

From what I understood
If location = 'ALL' then
fetch all the records
Else
add extra filter location_id = <supplied location id>
End If
If this is the condition the following logic should solve your issue.
open cv for
'Select col1, col2, col3, Col4
from t1, t2, t3
WHERE condition1
AND condition2
AND condition3'
AND ((location_id = location_id and location = 'ALL') or (location_id = location))Regards

Issue with dynamically setting where clause in OAF

and b.wip_entity_name=NVL(:6,b.wip_entity_name)
I need to pass dynamically a condition to my where clause that i can handle it by defining two bind parameters in the vo query and can pass it but the problem is the bind variable contains a string like 1311,13112,14445 that i need to pass for a field such as B.line_id in the first query and b.wip_entity_id in the second query so when i am trying by passing the string as one value it is working fine but for value separetd by comma it is giving prob.
so i tried by passing dynamic where clause but it is everytime executing for first clause only how i can pass dynamically both the queries.
vo.setWhereClause("LINE_ID in "+wherclause);
please help me out

How To change the ADF View Object query where-clause at RunTime?

I am trying to create a simple display page which will display user data (username, assoc_dist_id, assoc_agent_id, status , etc). The User data is stored in a database table and i am using an ADF Read Only table based on the View Object to display the data on the JSF page.
However, i want to display only the users that a particular person accessing the page has the AUTH LEVEL to see. e.g. If the person accessing the page is an 'ApplicationAdministrator' then the page should display all users in the table, If its a 'DistributorAdministrator' then the page should display only users associated with that Distributor (i.e. assoc_dist_id = :p_Dist_id ) and If its an 'AgentAdministrator' , then the page should display only users associated with that Agent ( i.e. assoc_agent_id = :p_Agent_id).
Currently my af:table component displays all the users in the table because the query for the view object is (select * from users) . However, i want to use the same viewobject and just set the where-clause at runtime with the appropriate parameter to restrict the dataset returned.
Do anyone knows how to accomplish this ?

David,
See the custom method initializeDynamicVariableDefaults() in the SRViewObjectImpl.java class in the FrameworkExtentions project in the SRDemoSampleADFBC sample application. You can find out how to install the demo if you haven't already from the ADF Learning Center at:
http://www.oracle.com/technology/products/adf/learnadf.html
This class is a framework extension class for view objects that adds a neat, generic feature to be able to dynamic default the value of named bind variables. You can read more about what framework extension classes are and how to use them in Chapter 25, "Advanced Business Components Techniques" of the ADF Developer's Guide for Forms/4GL Developers, also available at the learning center above.
It is an example of generic framework functionality that "kicks in" based on the presence of custom metadata properties on a named bind variable. See section 25.3.3 "Implementing Generic Functionality Driven by Custom Properties" in the dev guide for more details. Using this sample code, if you add a bind variable to a view object, and define a custom metadata property named "DynamicDefaultValue" on that bind variable, and set this custom metadata property to the value "CurrentUser", then that bind variable will have its value dynamically defaulted to the name of the authenticated user logged in. If instead you set this custom property to the value "UserRole", then the bind variable will be set to the comma-separated string containing the list of roles that the authenticated user is part of.
Once you've created a framework extension class for view objects like this, you can have the view objects you create inherit this generic functionality.See section 25.1.4 "How to Base an ADF Component on a Framework Extension Class" in the dev guide for more info on this.
By adapting a technique like this (or some idea similar that better suits your needs) you can have your view object query contain bind variables whose values automatically take on the defaults based on something in the user-session environment.

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:

Hello,
I have an APEX application that I need to build a SQL statement for a LOV (List of Values). I have a hidden filed that contains the customer type which can be an 'R' or 'B'. The query needs to be able to display two different result sets based on the customer type of 'R' or 'B'.
If the customer type is 'R' then:
SELECT drg_descr d, drg_code r
FROM distance_ranges
WHERE drg_min_miles IN (0,5)
ORDER BY drg_min_milesIf the customer type is 'B' then:
SELECT drg_descr d, drg_code r
FROM distance_ranges
WHERE drg_min_miles IN (0,5,10,15,20)
ORDER BY drg_min_milesCan someone help me with what I think needs to be a case statement?
Thanks,
Joe

Hi,
You can try CASE statement with WHERE clause
SELECT drg_descr d, drg_code r
FROM distance_ranges
WHERE (CASE param_cust_type
WHEN(param_cust_type='R') THEN (drg_min_miles IN (0, 5)
WHEN (param_cust_type='B') THEN (drg_min_miles IN (0,5,10,15,20)
END;
Please try and let me know if anything wrong.
Anyone from the forum comment my code if there is any wrong.
Thanks!

Dynamically setting where clause parameter before the page load

Hi Experts,
I do have the following requirement.
I am working on jsf page in ADF10.1.3.3. I have a View Object which displays the results on the screen. Can someone provide me some example where I can dynamically set the where clause parameter to my Query in VO before the Page Load happens(By Overriding the Prepare Model) and display results on screen.
Thanks

Hi,
Thanks for yor advice.
I need to write the method in Prepare Model method when the page loads and not in AM.
Here in the page there is no action as such.
On the Page load we need to directly set the Where Clause on the VO.
Provide me some examples if any.
Thanks

Where clause help.

Hi,
I have table with a partition on a column of date data type. Each partition has a month's data in it. I use the following query to fetch the data:
select column1, column2
from table1 partition(apr2011)
where trunc(date_column) = '01-APR-11';
The query works fast when partition has less records(data for 10-15 days). But as the number of records in the partition increases(at month end), the time taken to retrieve the result is much more. Request you to please help me with an alternative for the 'where clause' to get faster data.
Thanks.

Thanks Mohamed,

MDX query - need to run different query (where clause) on mondays

The below query works OK and uses the substitution variable CurrentWeek in the WHERE clause, but I have one shortcoming that I need your help for:
The query works fine for all days but mondays. On Mondays I need the query to fetch numbers from last week (as opposed to current week) as the query returns null as the cubes have no data for current week on mondays. Hence I need to change the where clause to use substitution variable LastWeek, or in some other way run a different query on mondays. I have another substitution variable called WeekDay which I can use to test which day of the week it is, but I am not sure of the syntax I need to use to test for day of week and then have the query use different substitution variables as a result of this test.
Please help.
Henning Strand
SELECT NON EMPTY {[Measures].[meas_sg]} ON COLUMNS,
NON EMPTY {[Kunde],[Kunde].[KU01],[Kunde].[KU02],[Kunde].[KU03],[Kunde].[KU04]} ON ROWS
FROM MIFS.MIFS
WHERE ([Marked].[Dagligvare],[Tid].[&CurrentWeek])

Or to go off of Sean's suggestion, programmatically change the value of the substitution variable, and leave the code alone.
Other thoughts -- have a load process to a single cell (sorry, my BSO roots are showing, but the concept is the same, load a single number) and then do a boolean test off its value -- 0 = Monday, 1 = the rest of the week.

Selecting values for query where clause

hi guys, this is possibly a silly question but not sure if i am approaching the solution in the correct mannor.
At the top of my form i have text box which the user fills in various values. These values are then used to refine the query results in the block below. I know i can go into the datablock being queried and set the where clause to equal the value of the text boxes above but i dont feel this is the right place to do it.
If i do it that way when the text box above is blank it returns no reults when infact i want to query everything if the values are left blank. So should i put it in pre query? if so what way should it be done?
Any help would be greatly appreciated.
Thanks.

Hello,
If i do it that way when the text box above is blank it returns no reults when infact i want to query everything if the values are left blank. So should i put it in pre query? if so what way should it be done?Not really if you use like below in block's where clause...
db_field_name1=NVL(:form_field_name1,db_field_name1) AND
db_field_name2=NVL(:form_field_name2,db_field_name2)-Ammad
