Where clause query logic

Dear friends,
can anyone explain how this query works. It display the employees with nth highest salary from emp table.
select empno,ename from emp e1 where n>=(select count(*) from emp e2 where e1.sal=<e2.sal)

Hi,
I don't understand your qury logic, did you want the employee into the N highest salary ?
So, try this :
select empno, ename, sal
from (select empno, ename, sal, dense_rank() over(order by sal desc) dr
from emp) e1
where e1.dr<=&n;[pre]

Does the 'default where clause' query select the ROWID by default ?

Hi ,
The query in default where property of a data block is as follows:
global.prim_lang = :global.user_lang
and upper(group_name) like upper('%' || :B_apply_inclusions.TI_group_desc || '%')
UNION ALL
select g.rowid, g.group_no
from table1 t,
table 2 g
where :global.prim_lang != :global.user_lang
and upper(g.group_name) = t.key(+)
and :global.user_lang = t.lang(+)
and upper(nvl(t.translated_value, g.group_name)) like upper('%' || :B_apply_inclusions.TI_group_desc || '%')
The g.rowid was added in the UNIONALL portion of the query because the first part of the query was bringing rowid as well.
We are in 10.1.2.3.0 forms version.
However for a user in forms verion 10.1.2.0.2, the query is giving an error " Unable to perform query " - due to mismatch in the number of columns selected in the query union.
because for this user, rowid is not selected as part of default where clause query( 1st part of the query before the unionalll).
If g.rowid is removed from the 2nd part of the query , it errors out in 10.1.2.3.0 forms version.
Could you kindly clarify when this rowid will also be selected by the default where clause of a block and why this issue is occuring?Is this issue related to forms version or any other property of the block? Is it is version based, is there a patch available to deal with the same?
Thanks in Advance.

You normally change the default_where block property just when you want to chnage the filter conditions for what is selected from a given block data source.
Querries with union or minus will confuse forms as to the rowid and will no longer be albe to perform the default insert/update/delete, not knowing the rowid and the table to perform the dml on.
A from clause query will be the best way to change dynamically the tables you select from and also the where. But, by using that, if you wish to insert/update/delete, you will have to use on-insert/update/delete triggers where the processing will have to rely on some primary key columns and not on rowid.
Or, instead of a from-clause, you may use a view, but that will definitely be less flexible than a from clause query.

Where Clause in Logical Table Source

I have a dimension table joined to a fact table in BMM Layter. I would like to apply a filter in the where clause of the dimension table. Does the fact table also require the same exact filter to be applied in the where clause.

It would be nice if you add that filter on Fact's where clause part, that would be for entire fact level(start schema) instead of only on table level
You might need to map the dim to fact to do so.

Dynamic query in where clause while looping in an internal table.

Hi,
Had a small question : How can i make a dynamic query for the WHERE clause while looping at an internal table.
i want to implement a dynamic where clause query for the below example.
it_cfx_col is an internal table and wa_cfx_col is a work area for it_cfx_col
DATA :
i_cfx_col TYPE TABLE OF cfx_col,
wa_cfx_col LIKE LINE OF i_cfx_col.
DATA : count TYPE i VALUE 0.
DATA : l_where_clause TYPE string,
         l_where_clause2 TYPE string,
         l_name type string.
l_name = 'NANDANOM'.
l_scenario = 'collaboration'.
LOOP AT it_cfx_col INTO wa_cfx_col
WHERE CREATED_BY = l_name
AND SCENARIO = l_scenario.
count = count + 1.
some business logic implemented using the work area wa_cfx_col
endloop.
Now i want to write a dynamic query for the where clause.
DATA : count TYPE i VALUE 0.
DATA : l_where_clause TYPE string,
         l_where_clause2 TYPE string,
         l_name type string.
l_name = 'NANDANOM'.
l_scenario = 'collaboration'.
l_where_clause = 'CREATED_BY = l_name'.
l_where_clause2 = 'AND SCENARIO = l_scenario'.
if l_scenario is not initial.
CONCATENATE l_where_clause l_where_clause2
INTO l_where_clause SEPARATED BY space.
endif.
LOOP AT i_cfx_col INTO wa_cfx_col
WHERE (l_where_clause).
count = count + 1.
some business logic implemented using the work area wa_cfx_col
endloop.
when i compile this i get an error message as { Statement concluding with "...(l_where_clause)" ended unexpectedly}
Even i changed the initilization of the variable l_where_clause2 to [ l_where_clause2 = 'AND SCENARIO = l_scenario.'. ]
added the end of line demarkation ".", but still i got the same error message.
Is it a limtation in ABAP that i cannot write a dynamic query for the where clause while looping at an internal table?
Regards,
om

Hi savita,
there in no such 1 limitaion in abap for dynamic query .. i think the error meassge is only beacuse of your synatx delcartaion.
>> LOOP AT i_cfx_col INTO wa_cfx_col
   WHERE (l_where_clause).
   count = count + 1.
some business logic implemented using the work     area    wa_cfx_col
   endloop.
afted delclarataion also , in the where statement you should specify both the field name and value bname
   LOOP AT i_cfx_col INTO wa_cfx_col
   WHERE l_where_clause = 'CREATED_BY = l_name' .
   count = count + 1.
hope it helps.

WHERE clause doesn't work in certain column

Hi All,
I try to filter mysql database using WHERE clause...everything seem working until i found there are 3 column that i can't use for WHERE clause query. When i use that columns to filter, there's no data appear in the table but the other column is working. Attached is my VI and mysql database. I really don't know what cause it happen. Any help would be very appreciated
Thank you

Have you tried the select from whatever SQL command interpreter that MySQL provides?
It needs to be in the form SELECT * FROM issue WHERE 'condition'. If you want to get all the rows where person 1 is Harry then you would write
SELECT * FROM issue WHERE person1 = 'Harry'
The way your VI is written you will get one of two commands.
SELECT * FROM issue WHERE 'All' or SELECT * FROM issue WHERE 'WIWI'
That may return all rows if a string resolves to true. I don't use MySQL so I wouldn't know.
Disregarding LabVIEW for a moment, what is the SQL command or commands that you want your VI to send to the ADO execute VI? That might help figure out what it is you want to do.

Passing values to Dynamic where clause as IN parameter - ADF

Hi,
I am trying to get the Dynamic where clause query output something like below,
select * from EMP where emp_id IN(200,203,204)
How to pass values from setWhereCluase(emp_id,????)
Thanks,

I'd go about this a little differently (probably not the best way):
1. Create view object lk_department (lookup). In the query add a union with something like "select null as ID, 'All' as name' from dual;". This adds a null value that they can select by leaving the combo box on "All". Add a 'order by id" so the null value is the first one. When creating the combo box you want it set to navigation mode, so select the whole viewobject from the data palette rather a specific field.
2. Create a jTextField for the "Jobs" field.
3. Create an application module method that does something like:
public void filterEmployees(String job){
ViewObject vo_departments = findViewObject("lk_departments");
ViewObject vo_employees = findViewObject("employees");
String wc = "1 = 1 ";
String wc = " and job like '%"+job+"%'"
if (vo_departments.getCurrentRow().getAttribute("Id") != null) {wc += "and department_id = "+vo_departments.getCurrentRow().getAttribute("Id");}
vo_employees.setWhereClause(wc);
vo_employees.executeQuery();
this.sync;
4. In your Jclient app, you just need to call the method of your appmodule and insert the string from the textbox, using code similar to this:
AppModule b = (AppModule)panelBinding.getApplicationModule();
b.filterEmployees(jTextField.getText());
I didn't test this code, but that's how I go about the same thing.

Using Parameters in SQL-Query not only in where clauses

Hi,
I try to use Publisher parameters in the SQL Query from a Data Set.
All of them have default values.
So far, this is no problem, unless I try to use such a parameter value as an ordinary attribute value:
>
select
 case when (:pv_Group = 'no') then "DM15D_BETRIEBSTEIL"."BETR_TEIL"
 else :pv_some_Text end as Betr_Teil,
 case when (:pv_Group = 'no') then "DM15D_BETRIEBSTEIL"."SUVA_NR_FORM"
 else :pv_some_Text end as Suva_Nr,
 case when (:pv_Group = 'no') then "DM15K_RIS_FAKTEN_PRO_BTT_JHR"."RIS_VOLLBESCH"
 else sum("DM15K_RIS_FAKTEN_PRO_BTT_JHR"."RIS_VOLLBESCH") end as Vollbesch
from "GDWH05"
where
 "DM15D_BETRIEBSTEIL"."SUVA_NR_FORM" in (:pv_nim100)
 fetch first 65001 rows ONLY
>
The parameters 'pv_Group' and 'pv_nim100' are working fine. (when or where clauses)
The parameter 'pv_some_Text' unfortunately not. (simple literals)
When I try to validate the above SQL, I get the following Error:

java.io.IOException: prepare query failed[nQSError: 43113] Message returned from OBIS. [nQSError: 46033] Datatype: 25 is not supported.

After use a cast function:
>
else CAST(:pv_some_Text AS CHARACTER)
>
I get this ERROR:

java.io.IOException: prepare query failed[nQSError: 43113] Message returned from OBIS. [nQSError: 19002] Incorrect use of parameters. The parameters used in CAST cannot be resolved without ambiguity.

We use OBIEE 11.1.1.6.4 on a Win64-System.
Thank's for any help.

Hi Alex,
let's leave away any unnecessary details.
This is the SQL, inserted in the window 'Edit Data Set' of BIP Data Model:
>
select
 '--1' as Betr_Teil,
 '--2' as Suva_Nr,
 sum("GDWH05"."DM15K_RIS_FAKTEN_PRO_BTT_JHR"."RIS_VOLLBESCH") as Vollbesch
from "GDWH05"
where
 "DM15D_BETRIEBSTEIL"."SUVA_NR_FORM" in ('122-4.4')
 fetch first 65001 rows ONLY
>
Everything is fine when I click OK, the script goes back to the metadata.
Let's try this script with bind values in ORACLE SQL Developer.
This SQL is the physical part, found in the OBIEE-Log (Log level 5), except the bind values. Therefore we find, in the where clause, the join. In the logical sql, we don't have to join, because it's handled in the Common Enterprise Information Model (CEIM)

This SQL works fine, even with bind values for 'pv_some_text'.

from "GDWH05"
where

The following ERROR occurs:

In my opinion, either I use a wrong syntax, or BIP has a problem with parsing the script.
Thank you for your most welcome help.

Very slow query when specifying where clause

Hi folks:
I am using SAS with SQL Passthrough for Oracle, however that may be irrelevant to the problem.
I have a query that I am subsetting based on a series of where clauses, and when I put the clauses into the query, it slows it down tremendously.
I can pull the entire table and subset it later on in SAS and it is much faster.
Can someone explain why the SQL subsetting logic runs slower than pulling 18M rows and subsetting later?
Here is my query - hope this is enough information
select
a.loan_number
, a.CFLRC_CD
, a.cservno
, b.cprj_typ
, a.occ_stat
, c.state2
, c.city2
, e.hstatus
, e.hcattype
, e.dqind
, e.mthsdel
from
VEW_LL_ln_1 a
, vew_ll_ln_2 b
, VEW_LL_PROP_GEO_CD c
, vew_ll_ln_actvy_1 e
where
a.loan_number = b.loan_number
and a.loan_number = c.loan_number
and a.loan_number = e.loan_number
and e.act_dte = '01-feb-2011'
and not (occ_stat in ('2','3'))
and hcattype <> '800'
and dqind not in ('E','F','G','H')
and cprj_typ not in ('1','2','3','4','5','16','17','18','19','20','21','22')

Variable in where clause of the logical table

Hi,
is it possible to define a variable in "where" clause of rpd's physical table (table type - select)? If yes, pls elaborate the steps including how to refresh it with every end user's request?
Thanks and Regards,
Igor
P.S.
If not, is there any workaround?

Nico
thanks, but I am afraid that is not my case. I need to refresh variable value interactively with every query by a dashboard prompt. To illustrate my need just imagine a recursive SQL (defined as a view/logical table in rpd):
SELECT ....
FROM ...
WHERE ...
START WITH .... columnA=variable1
CONNECT BY PRIOR .... and columnB=varariable2;
or
SELECT c1,c2,c3,c4 from tabA where c1='A' and c2=variable1
union
SELECT c1,c2,c3,c4 from tabA where c1='A" and c2='D' and c1 NOT IN ( SELECT c1 FROM tabA where c1='A' and c2=variable1 );
So, what I want to do is to pass value(s) to my variable(s) every time when respective select (view) is executed. I see above selects are not typical ones the OBI EE is intended for but nevertheless I wonder if such kind of reports are possible to do in OBI EE.
Thanks and Regards,
Igor

Performance hit using "where" clause in the query

Hi All,
I am facing a huge performance hit in the java code when using "where" clause in queries. Following are the details:
1. SELECT * FROM Employee
2. SELECT * FROM Employee where employeeid in (26,200,330,571,618,945)
There is no difference in Query Execution Time for both queries.
Business Logic Time is huge in second case as compared to first one (ratio - 1:20).
Rows returned are more in first case as compared to second case.(ratio - 1:4)
Business Logic is same for both the cases where I iterate through the ResultSet, get the objects and set them in a data structure.
Does anybody know the reason of unexpected time difference for the business logic in the second case?

Since you're mentioning clustering your index, I'll assume you are using Oracle. Knowing what database you are using makes it a lot easier to suggest things.
Since you are using Oracle, you can get the database to tell you what execution plan it is using for each of the 2 SQL statements, and figure out why they have similar times (if they do).
First, you need to be able to run SQL*Plus; that comes as part of a standard database installation and as part of the Oracle client installation - getting it set up and running is outside the scope of this forum.
Second, you may need your DBA to enable autotracing, if it's not already:
http://asktom.oracle.com/~tkyte/article1/autotrace.html
http://www.samoratech.com/tips/swenableautotrace.htm
Once it's all set up, you can log in to your database using sql*plus, issue "SET AUTOTRACE ON", issue queries and get execution plan information back.
For example:
SQL> set autotrace on
SQL> select count(*) from it.ticket where ticket_number between 10 and 20;
COUNT(*)
 11
Execution Plan
Plan hash value: 2983758974
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 4 | 1 (0)| 00:00:01 |
| 1 | SORT AGGREGATE | | 1 | 4 | | |
|* 2 | INDEX RANGE SCAN| TICKET_N10 | 12 | 48 | 1 (0)| 00:00:01 |
Predicate Information (identified by operation id):
 2 - access("TICKET_NUMBER">=10 AND "TICKET_NUMBER"<=20)
Statistics
 0 recursive calls
 0 db block gets
 1 consistent gets
 0 physical reads
 0 redo size
 515 bytes sent via SQL*Net to client
 469 bytes received via SQL*Net from client
 2 SQL*Net roundtrips to/from client
 0 sorts (memory)
 0 sorts (disk)
 1 rows processed
SQL> This tells me that this query used an INDEX RANGE SCAN on index TICKET_N1; the query can't do much better than that logically... In fact, the statistic "1 consistent gets" tells me that Oracle had to examine only one data block to get the answer, also can't do better than that. the statistic, "0 physical reads" tells me that the 1 data block used was already cached in Oracle's memory.
the above is from Oracle 10g; autotrace is available back to at least 8i, but they've been adding information to the output with each release.
If you have questions about sql_plus, check the forums at asktom.oracle.com or http://forums.oracle.com/forums/category.jspa?categoryID=18
since sql*plus is not a JDBC thing...
Oh, and sql*plus can also give you easier access to timing information, with "set timing on".

Avoid repeating same logic in 'select' and 'where' clauses?

I'll preface by saying I'm self-taught and have only been fiddling with SQL for a couple of months, so forgive me if this is a dumb question. I have a query written to pull out customers who are configured to have their products stored at the wrong warehouse, according to the first 3 digits of the zip code. Here is an extremely simplified version of a query I'm trying to run:
select custno, custbuy_zip_cd, custbuy_prim_ship_loc_cd as Warehouse,
case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
end as StdWhse
from customers
where case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
end <> custbuy_prim_ship_loc_cd
or (case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
end is not null and custbuy_prim_ship_loc_cd is null)
Now, the query works, but it seems overly convoluted and feels like there must be a way to make it simpler and faster. I'm using the same 'case when' 3 times. Originally, I had thought I could use the aliases from the 'select' clause in the 'where' clause, which would simplify things:
select custno, custbuy_prim_ship_loc_cd as Warehouse,
case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
end as StdWhse
from customers
where StdWhse <> custbuy_prim_ship_loc_cd
or (StdWhse is not null and custbuy_prim_ship_loc_cd is null)
I then found out that that caused 'invalid identifier' errors. My first attempt at a solution was to use a subquery in the 'from' clause, but that ran the 'case when' on every single customer instead of the small subset, so it wound up taking much longer even though it looked neater. Any tips on how to clean up that first query to make it run faster?
this is Oracle 11i, I believe. As a side note, I don't have write access to the database.

Thanks for all the tips so far - still going through them. You all respond fast! Sorry about using double angle brackets for != and not using code tags, I'll make sure to format my posts properly going forward. I think the double angle brackets messed up the appearance of my original queries a little. Here's how I probably should have pasted my first query in my first post:
select custno, custbuy_zip_cd, custbuy_prim_ship_loc_cd as Warehouse,
 case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
 when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
 end as StdWhse
from customers
where case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
 when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
 end != custbuy_prim_ship_loc_cd
 or (case when substr(custbuy_zip_cd,1,3) in ('839','848') then '20'
 when substr(custbuy_zip_cd,1,3) in ('590','591') then '33'
 end is not null and custbuy_prim_ship_loc_cd is null)The almost unanimous opinion seems to be that I should use a subquery in one way or another, but the problem remains that the only significant logic to narrow down the results is the logic that matches the 'case when' results (which are what the warehouse number should be, based on the zip code) to the current warehouse number. Therefore, it seems like any subquery is going to return my entire list of 600k customers, and take a much longer time than my original (messy) query. At least it has in the test runs I created based on
Satyaki's and Peter's examples. The query based on my original example takes about 2.5 minutes, and the subquery examples take about 5+ even though they look cleaner.
to clarify what the query is trying to accomplish, I want it to pull any records where the warehouse number does not equal the correct warehouse number based on zip code (or if the warehouse number is null when it shouldn't be).
I'll try to create some sample data and sample results. Customers table:
custno custbuy_zip_cd custbuy_prim_ship_loc_cd
1 59024 20
2 59024 33desired results:
custno custbuy_zip_cd warehouse StdWhse
1 59024 20 33If I could create a table to hold the standard warehouses to join on, the whole thing would be much easier. The full version of the query really has hundreds of zip code prefixes and 5 different warehouses and each account has 4 alternate warehouses as well. However, I'm stuck with read only access so everything has to go right in the query. It wouldn't be the end of the world to just stick with my original query since it's not like it takes hours, and I'll only be running it weekly. I just wanted to make sure there wasn't some other solution that wasn't just cleaner but was also faster.

Dynamic WHERE clause logic in SQL based on ITEM value

Hi,
I have a report based on following SQL query.
   select dept_no,
       dept_name,
       dept_loc
from dept
where dept_loc = :P1_DEPT_LOC
   // If P1_DEPT_LOC is not null, I want the WHERE clause and IF P1_DEPT_LOC is null, then I don't need the WHERE clause.
   // how can I build this logic in same SQLThanks,
Deepak
Edited by: Deepak_J on Mar 11, 2010 4:37 PM

Deepak,
If p1_dept_loc were a LOV, this would work.
SELECT deptno,
dname,
loc
FROM dept
WHERE ( :p1_dept_loc = '%null%' OR loc LIKE '%' || :p1_dept_loc || '%' )

Linq to XML query where clause excluding null attribute in child

I'm quite new to linq/XML and although I'm making progress I'm stuck at combining two levels of elements in a where clause. The XML is something like this
<employees type="cashier">
<employee hired="Jun 1 2000" fired="Jun 1 2013">
<stats name="jane doe">
... other stuff ...
<stats />
<employee/> <employee hired="Jun 1 2000">
 <stats name="john doe">
 ... other stuff ...
 <stats />
 <employee/>
<employees/>
I'm trying to retrieve all employees of type "cashier" that haven't been fired.
I tried this
IEnumerable<XElement> CashierElements = from el in xDoc.Root.Descendants("employees")
where (string)el.Attribute("type")=="cashier"
&& (string)el.Element("stats").Attribute("fired") != null
select el;
But that returns entries where the fired attribute doesn't exist. I'm not even sure I can reference the stats element attribute in this way but VS2013 doesn't complain about it.
I have managed to muddle past by using two linq selections, the one above without the stats comparison followed by a second on the results that checks for "fired" being null.
How would I achieve this with one select statement?
Thanks!

Hi,
1) Your XML contains the attribute "fired" on "employee" element. Your query search this attribute on the "stats" element.
2) you say "that haven't been fired" by you search an attribute fired != null ? I'm not sure about your logic.
If I understand your request, your LINQ Query is more than :
IEnumerable<XElement> CashierElements =
// Loop on <employees>
from emps in xDoc.Root.Descendants("employees")
// only 'cashier' type
where (string)emps.Attribute("type") == "cashier"
// Loop on <employee> in filtered <employees>
from emp in emps.Elements("employee")
// only the employee not fired
where emp.Attribute("fired") == null
// select the employee element
select emp;
