Have MAX in WHERE clause

Hi everyone,
Is there a way to use MAX in the WHERE clause as follows:
where . . .
and max(dte_end) between x.dte_pa_auth_eff and :il_current_date
and . . . .
any help would be greatly appreciated.
Thanks

Here is an example:
I am trying to compare two dates
I have the following values:
SAK_RECIP DTE_EFFECTIVE DTE_END
113013 20050601 20051231
113013 20060101 22991231
113013 20050101 20050531
113013 20040601 20041231
I am joining two tables using the sak_recip, and i get all those rows, but i only want to compare the latest dte_end. but it is comparing all the dte_end.
Hope this helps to understand my problem.
Thanks

Dynamically changing the WHERE clause in detail VO in Master Detail

Hi, I want to develop a search functionality, results will be in a table, which will have an inline table displaying the details per row found.
I have a MD defined trough viewlink. I do change the master VO at runtime (set the entire SQL), based on the criteria entered by the user.
Is there a way to change the VO at the detail end of the link at runtime - that is what I haven't been able to do.
I have read that the ADF framework creates internal VO for each master row, whenever accessed trough accessor (which is not I am trying to do). I haven't been able to find a way to get a hold of the REAL VO at the detail end and have its WHERE clause changed.
Changes to the "VO instance in AM" (same one used as a definition in the detail end in the ViewLink def) does not seem to reflect the detail VO.
I have a MasterView, DetailView, MasterDetailLink (MasterView->DetailView).
MasterDetailLink is used to create a table with inline detail table. At runtime:
1.get MasterView (from AM), change query trough setQuesry() - works.
2.get DetailView (from AM), change query trough addWhereClause() - does not work (no exceptions) - the results I am getting DO NOT reflect the conditions of the where clause, I mean the clause have not been addedd.
I 've looked at the logs (debug enabled) and it seems to me that there no "activities" related to the detail VO, even after the where clause of the VO from step 2 is changed.
Looks like there is a separate VO which I would like to get a hold of :)
Thanks, and sorry for the long explanation

After you have added a new where clause on the detail VO, try re-executing VO's query by DetailVO.executeQuery()
If it doesn't work try re-executing the MasterVO's query after you have added the where clause on the detail

Pass values dynamically to the WHERE clause in SFAPI

Hi there
We have a requirement to pass values dynamically (in the run-time of the interface) to the WHERE condition to our SFAPI query.
Eg -
SELECT person, personal_information, address_information, phone_information, email_information, employment_information, job_information, compensation_information, paycompensation_recurring, paycompensation_non_recurring, job_relation, accompanying_dependent,         global_assignment_information, direct_deposit, national_id_card, person_relation
          FROM CompoundEmployee
          WHERE last_modified_on >= to_date('LAST_RUN_DATE') AND
                       last_modified_on <= to_date('CURRENT_RUN_TIME')
LAST_RUN_DATE is stored in a custom entity for which we execute another OData query. The custom entity is updated with the CURRENT_RUN_TIME once the interface has been executed successfully. So the next time the interface is run it picks up the LAST_RUN_DATE from the custom OData entity.
SAP PO has the functionality to run a dynamic query for OData adapters. Refer to Note 2051137 - PI Successfactors adapter : Dynamic odata query and single synchronous sfapi query
Eg - select fields from position (this is what you state in OData query path in the comms channel; this is static); and you have an advanced tab in comms channel where you mention dynamicquery and set it to true (this points to a XSD which has the keyword TOP, SKIP & FILTER in it).
This gets the filter values passed from the BPM from another query (from a OData cust_table).
So the whole query is - select fields from position filter field a = x field b = y etc. Field a field b are fields in position that are you passing values x and y in run time of the interface.
SAP PO also has the advanced tab feature for SFAPI for dynamic query.
Question is -
how to use it?
has anyone implemented this before?
What does XSD will look like?
How do we pass values to the fields to the Where clause for SFAPI.
Any ideas are welcome!

Arijit Das

Where clause in Data Block

I'm running Forms 6i client/server.
I have defined a where clause in the Property Palette for a Data Block.
What I like to do is to extend the where clause with a subquery, but
how can this be done? I mean, should I put the code in a trigger, which trigger?
Regards
Roar

simple where clause with sub_query
My block has name is dc_gmod. In the where pallete I put the text (and the all is work good!!!):
exists
select 1 from ttt.xxxxx_table v
where (dc_gmod.cd_gmod = v.cd_gmod)
and
(instr(:fst.tmp_nm,cd_place,1) > 0
or
cd_place IN
(select U_UNIT from ttt.xxxxxxxxx_tabe
where RG_U = :QA.RG_UNIT_RUN
AND SID = :QA.SID
AND SERIAL# = :QA.SERIAL
1.The dc_gmod.cd_gmod - is full name my block_name and item_name.
2. The ttt.xxxxx_table is full name of my table what is source for block dc_gmod
3. The cd_place is ITEM of BLOCK dc_gmod

Where clause and order by to DAO classes

Hi
Is it ok(I mean design wise) to pass the 'where clause' conditions and order by clause as a parameter to the method of DAO class?

Well, I would suggest you write seperate methods in your dao , one to select data without the where clause and one to select data with the where clause thrown in. If you have different 'where' clauses for selecting different kinds of data, have that many dao methods. The dao methods being specific know exactly what is the data that's coming in.
Lets assume you have a list of purchase orders and each purchase order is indetified by a unique id called PURCHASE_ORDER_ID.
1. The following code would populate a purchase order's details given an id.
private statis final String QUERY_1 = "select * from PURCHASE_ORDERS where PURCHASE_ORDER_ID = ? ";
PurchaseOrderModel getPurchaseOrderData(long poId){
     //get a prepared statement from your connection
     PreparedStatement pst = conn.prepareStatement(QUERY_1);
     //set the poId passed as params to your query
     pst.setLong(1, poId);
     ResultSet rs = pst.executeQuery();
     if(rs.next()){
          //populate data into a model
     finally{
          //clean up resources
     return model;
}2. The following code would return a list of PurchaseOrderModel's whose shipping date falls between a set of dates selected by the user.
private statis final String QUERY_2 = "select * from PURCHASE_ORDERS where SHIPPING_DATE between ? and ? ";
PurchaseOrderModel getPurchaseOrdersBetweenDates(list bindValues){
     //get a prepared statement from your connection
     PreparedStatement pst = conn.prepareStatement(QUERY_1);
     //set the dates passed as params to your query
     //we know that the List ought to contain only 2 dates
     pst.setDate(1, (Date)bindValues.get(0));
     pst.setDate(2, (Date)bindValues.get(1));
     ResultSet rs = pst.executeQuery();
     if(rs.next()){
          //iterate and populate data into a model
          //add model to a list
     finally{
          //clean up resources
     return list;
     3. This is more interesting - the dao method searches a list of Purchase Orders starting with a set of specific words. The words themselves may be one or many. This means that the number of '?' in your prepared statement may be dynamic. Each element of the list is a String that contains the start substring of a purcahse order name. For example - the list may contain elements like ["a", "ab", "c", "gh"] and the dao method returns all purchase order starting with these names.
private statis final String QUERY_3 = "select * from PURCHASE_ORDERS where ";
PurchaseOrderModel getPurchaseOrderNameMatches(list bindValues){
     //construct the query dynamically
     StringBuffer query = new StringBuffer(QUERY_3);
     int count = 0;
     for(Iterator itr = bindValues.iterator(); itr.hasNext();;){
          String value = (String)itr.next();
          query.append ("name like 'value%' ");
          if (count != 0 and (count+1 != bindValues.length)){
               query.append(" or ");
          count ++;
     //get a prepared statement from your connection
     PreparedStatement pst = conn.prepareStatement(query.toString());
     ResultSet rs = pst.executeQuery();
     if(rs.next()){
          //iterate and populate data into a model
          //add model to a list
     finally{
          //clean up resources
     return list;
To sum up,
1. You need as many methods as you have different kinds of searches (one method for each kind of 'where' clause).
2. The ejb/business layer would examine the data and decide on which method to call.
3. Increases coding effort, but makes the code clean and readable. Each layer does it's job. Thus we dont have ejbs forming 'where' clauses and so on.
Having said that, it really is your decision - you should take into consideration the following factors -
1. How big is the project ? If its a huge codebase developed by many people, then segregate the responsibilities clearly in each layer as I have outlined. For a small scale project, you could go with your approach.
2. Whats the take on maintenance and future add-ons ? Do you see the codebase growing with time ?
3. Is your project a commercial one - is it a product that needs to be maintained or is it a one-off development - develop once and you are done with it.
4. What are the design considerations ? Is somebody going to audit code for quality ? Or is it a academic one ?
You should take into account all these before deciding to go one way or the other.
A general thumb rule should be that you should be convinced that your code readable (maintainable), scalable and efficient. Anything that you do towards these ends is good code/design despite what people/books/patterns say, IMO.

Select avoiding where clause

Hello,
I am using JPA in my app and I am confused because of a select that is returning data as I didn't have anything in my where clause.
Select A (with problems):
Query q = em.createQuery(
" Select distinct p "+
" From Subgrupo sub,"+
" UsuarioSubgrupo usb," +
" Usuario u, "+
" Grupo g, "+
" Projeto p "+
" where "+
" sub.cdGrupo = g.cdGrupo and "+
" g.cdProje = p.cdProje and "+
" g.stAdmin = 1 and " +
" sub.cdSubgr = usb.cdSubgr and " +
" usb.cdUsuar = u.cdUsuar and " +
" u.cdUsuar = 1"
Select B (almost OK):
Query q = em.createQuery(
" Select p.dsProje "+ // the only difference
" From Subgrupo sub,"+
" UsuarioSubgrupo usb," +
" Usuario u, "+
" Grupo g, "+
" Projeto p "+
" where "+
" sub.cdGrupo = g.cdGrupo and "+
" g.cdProje = p.cdProje and "+
" g.stAdmin = 1 and " +
" sub.cdSubgr = usb.cdSubgr and " +
" usb.cdUsuar = u.cdUsuar and " +
" u.cdUsuar = 1"
In the second select, I've got the rows according with where clause and I cannot understand how the fact of selecting an objetc Projeto (p) (select A) can make such a "mess" avoiding the rules of the where clause.
Could someone give me a help about this problem?
I'll be glad with any help!!

!_Let's share ideas_!

Hi,
The issue is I am getting differents results from selects A and B and both have the same where clause.
I have done this:
Query q = em.createQuery(
" SELECT NEW entity.Projeto (p.dsProje, p.cdProje) "+
" From Subgrupo sub, "+
" UsuarioSubgrupo usb," +
" Usuario u, "+
" Grupo g, "+
" Projeto p "+
" where sub.cdGrupo = g.cdGrupo "+
" and g.cdProje = p.cdProje "+
" and g.stAdmin = 1 "+
" and sub.cdSubgr = usb.cdSubgr "+
" and usb.cdUsuar = u.cdUsuar "+
" and u.cdUsuar = " + cdUsuar
I am getting what I need, but the reason why a simple select p does not work I don't know.
This select is not generate by TopLink.
Cheers!

ADF dynamic where clause for VO query using BC

I'm hoping someone can help me out. I have a read only view object that I want to filter results based on some user choices. For example the user may want to see all results or they may only want to see a much smaller subset. This is for an error dashboard, the smaller subset maybe by application or maybe by application and by error severity. I think I can use a dynamic where clause but I'm not sure, Can someone get me started down the right path, or post an example that I can see.

Hi user,
You can use a dynamic where clause for this, but maybe there is a more practical option. Maybe you can have a fixed where clause, but using a bind parameter, like:
vo.application like :applicationParam. This makes an executeWithParams method available that you can call from your page, and use in the bindings. This parameter you can populate with the results of for example a poplist, with a default value of '%'.
When you do want to use a dynamic where clause, you will need to add a method to the java code of your application module, and make this method available for the client. In this method, you can use findViewObject to retrieve your VO, use VO.setWhereClause to set the whereclause to what you want, and then call VO.executeQuery. This method can then again be called from the page.
Success,

DECODE inside the WHERE clause

Hello All:
I can't get the DECODE statement to work inside my WHERE clause. I have read the information on
tahiti.oracle.com
http://download.oracle.com/docs/cd/E11882_01/server.112/e17118/functions049.htm#i1017437

EO and VO where clauses

I am working on some customizations for a client. I'm trying to query PoReqDistribuitionsVO for a particluar Requisition Line id and it is not working. I've looked at the queries both in the VO definition and using the VO getquery method and I noticed that the .getquery() method returns the query with where clause appeneded even if I execute .setWhereClause(null) just prior to it.
The where clause is filtering where the requistion_line_id = :1
I have two questions.
1) where is this where clausing coming from since it is not part of the VO definition
2) How can I set the bind parameter on this mystery where clause?
If I use the VO.setWhereClauseParams() method, I get a sql error of no such bind variable exists.
Thanks in advance for any help.

1) You can dynamically set the where clase from the AM or one of the method initQuery() inside the VOimpl.java.
This is a simple step to set where clasue dynamically.
public void initQuery(String yourid )
setWhereClauseParams(null); // Always reset
setWhereClause("Pid = :1");
setWhereClauseParam(0, "123");
executeQuery();
This initQuery is called from your Am method, for example vo.initQuery() instead of executing vo.executeQuery().
2) The reson you are getting error becuase , becuase you may have not set where clause before setWhereClauseParam. See example above.
One more thing to be careful is the indexing of the bind parameter, in case of setWhereClause() , the index start with 1 and in cae of setWhereClauseParam() , index start with 0.
hope this help.

I see a couple of problems here.
First, what you posted below is not a syntactically valid query. It seems to be part of a larger query, specifically, this looks to be only the GROUP BY clause of a query.

trunc(max(RD.DATERECEIVED)) BETWEEN TO_DATE('01/08/2011','DD/MM/YYYY') AND TO_DATE('01/08/2011','DD/MM/YYYY')you should do it in a HAVING clause, not a where clause:
select ....
from ....
where ....
group by ....
having max(some_date) between this_date and that_date;Hope that helps,

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)

Can't have aggregate function in WHERE clause clause

Dear all,
I've created object in BO XI 3.1 Designer with following criterias:
http://img4.imageshack.us/img4/833/20111201124314.th.jpg
It is a simple number - 1,2,3,4,5.
Now I need to use this object as a criteria for WHERE function in another object.
http://img607.imageshack.us/img607/1543/20111201124717.th.jpg
I receive an error "Can't have aggregate function in WHERE clause <clause>"
How can I overcome this?
P.S. I'm sorry in advance if such topic already exist - I didn't found one.

Hi,
You will have to use Sub query to achieve this. Give more details on what is available and what you need then i could help you out with the complete solution.

Can a recursive sql have a where clause

can the following sql have a where clause and I dont want to hard code the id is is that possible...
select DISPLAY_NAME, ID, PARENT_ID, display_in_parent_folder, sub_folder_sequence
from wwsbr_all_folders start with id = 8888
connect by prior id= parent_

actually g is another alias I created sorry I missed it... if I do this as a regular sub query I get three records but when I implement it as a recursive query it does not retutn any thing. Below is my regular query followed by the recursive query which I am using to organize the result but get no results:
REGULAR Query that retrieves records with parent_id = from the list of parent ids
select distinct f.DISPLAY_NAME, f.id, f.type_id, f.type_siteid, f.base_type_id, f.parent_id, f.sub_folder_sequence
from WWSBR_ALL_FOLDERS f, WWSBR_ALL_FOLDERS g
     where g.parent_id = ( select g.parent_id from WWSBR_ALL_FOLDERS e
where
     e.caid = 103 AND
e.parent_id <> 0 AND
e.type_id = 1 AND
e.display_in_parent_folder <> 0 AND
     e.id = f.parent_id)
order by f.id, f.sub_folder_sequence;
Recursive query that results nothing:
select distinct f.DISPLAY_NAME, f.id, f.type_id, f.type_siteid, f.base_type_id, f.parent_id, f.sub_folder_sequence
from WWSBR_ALL_FOLDERS g, WWSBR_ALL_FOLDERS f start with f.id = ( select g.parent_id from WWSBR_ALL_FOLDERS e
where
     e.caid = 103 AND
e.parent_id <> 0 AND
e.type_id = 1 AND
e.display_in_parent_folder <> 0 AND
     e.id = f.parent_id)
     connect by prior f.id= g.parent_id
order by f.id, f.sub_folder_sequence;

Cardinality estimator 2014 is off with OR in where clause

Here is my test setup on SQL Server 2014.
-- Create big table
CREATE TABLE [dbo].[Store](
Id int IDENTITY(1,1) NOT NULL,
City int NOT NULL,
Size int NOT NULL,
Name varchar(max) NULL,
CONSTRAINT [PK_Store] PRIMARY KEY CLUSTERED ([Id] ASC)
GO
CREATE NONCLUSTERED INDEX [IX_Store] ON [dbo].[Store] (City ASC, Size ASC)
GO
-- Fill with 100k rows
INSERT Store
SELECT i % 101, i % 11, 'Store ' + CAST(i AS VARCHAR)
FROM
(SELECT TOP 100000 ROW_NUMBER() OVER (ORDER BY s1.[object_id]) AS i
FROM sys.all_objects s1, sys.all_objects s2) numbers
GO
-- Create small table
CREATE TABLE #StoreRequest (City int NOT NULL, Size int NOT NULL)
GO
INSERT #StoreRequest values (55, 1)
INSERT #StoreRequest values (66, 2)
Now I execute the following query (I force the index to show statistics estimates)
SELECT s.City
FROM #StoreRequest AS r
INNER JOIN Store AS s WITH(INDEX(IX_Store), FORCESEEK)
ON s.City = r.City AND s.Size = r.Size
WHERE s.Size <> 1 OR r.City <> 55
Here are the estimates that I get (I'm not allowed to upload pictures):
Index Seek IX_Store
Actual Number of Rows: 90
Estimated Number of Rows: 50000
Fixing WHERE clause to use one table not two makes the estimate perfect:
SELECT s.City
FROM #StoreRequest AS r
INNER JOIN Store AS s WITH(INDEX(IX_Store), FORCESEEK)
ON s.City = r.City AND s.Size = r.Size
WHERE s.Size <> 1 OR s.City <> 55
Index Seek IX_Store
Actual Number of Rows: 90
Estimated Number of Rows: 89.74
Switching to 2012 compatibility mode gives estimate of 1 in both cases:
Index Seek IX_Store
Actual Number of Rows: 90
Estimated Number of Rows: 1
Could anyone explain the first result? I'm a bit worried about it. The fix in this case is trivial, but this problem gave us quite some headache in more complex real life queries with multiple joins.
Thank you!

But not full statistics on a field basis, just sometimes some default stats like total row count that some plans will build. Even your StoreRequest table only has one two-field index that will have a full histogram.
But I've seen SQL Server make massively bad plans on two-field indexes.
I've seen SQL Server go wrong one-column indexes, so that is not a very relevant point.
Temp tables or not, the estimate here is clearly incorrect. SQL Server knows the density of Size and City. It knows the cardinality of the temp table. The density information gives how many rows the the join will produce. The WHERE clause will then remove
a certain number of rows. With no statistics for the temp table, it does not now how many, but it will apply some standard guess.
50000 is a completely bogus number, because the join cannot produce that many rows, and SQL Server is able to compute the join with out the WHERE clause decently. (Well, it estimates 90, when the number is 180.) No, this is obviously a case of the cardinality
estimator giving up completely.
It is worth noting that both these WHERE clauses gives reasonable estimates:
WHERE r.Size <> 11 OR r.City <> 550
WHERE s.Size <> 11 OR s.City <> 550
Whereas these two gives the spooky 50000:
WHERE s.Size <> 11 OR r.City <> 550
WHERE r.Size <> 11 OR s.City <> 550
