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!

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.

Select Statement -- Where Clause Execution Order

What is the order of execution of the "AND" and "OR" in the WHERE clause of a Select statement?
Are the "AND"'s executed from the top down, left to right? Is it the same for the "OR"'s execution?
Thanks for any help...

Not clear why you care. There is an order in which the optimizer parses the SQL (which may change from ver to ver), but this is a fairly quick operation. The order in which tables are visited and predicates evaluated is dependent on what the op[timizer does with the SQL.

PL/SQL: how to use in parameter in select sql where clause

Hi
in a procedure, I need to apply 'in parameter' in 'where clause' along with other table fields. Purpose is to create dynamic select querry with multiple conditions.
select count(*) from table xx
where y_code=2008 and v_type in ('SI', 'TI', 'DI') ;
my requirement is replace 'and v_type in ('SI', 'TI', 'DI')' with in parameter. pls note in paramter may contain null value.
Regards

... e.g. why on earth do you want to pass in a string to be appended to the WHERE clause of an SQL.I second that and I strongly advice NOT to do it. If you really want to do it, then come back and show us, how you would prevent SQL injection. This approach is too dangerous (and too complex) IMHO.
Do it straight forward as in the article of Tom Kyte (link in the post of BluShadow above)

Dynamic page with multiple select in where clause

Hi,
I have a dynamic page and in the where-clause, i have a bind variable. In a report i use for instance
and rtrim((to_char(date_time5,'DAY'))) IN :v_day
That works ok in a report. But it does not work in a dynamic page.
what code is needed to work with a multiple select box on the customize screen for a dynamic page?
Thanks.

Hi.
I have a dynamic page, with a bind variable :v_day. On the customization screen the user can select one or more days of the week, or all days. I use this also in a report and then it works ok. In the where clause i use:
and rtrim((to_char(date_time,'DAY'))) IN :v_day
Date_time is a tablecolumn (date).
When i add this line in the select script from the dynamic page, i get error:
: ORA-06550: line 1, column 2443:

Offset operation in select statements where clause

dear experts,
    if i use offset operation in select query , syntactically giving
    me a warning message.
    how to avoid warning message
    without using another internal table populated with only jtab+0(10).
   ex:
          select field1 field2
                    into table   itab
                    from ztable1
                    for all entries in jtab
                    where field = jtab+0(10).
thanks in advance.

No need to populate another internal table...
when populating jtab from database select ur field twice
structure for jtab..
types: begin of ty_jtab,
          field type ...
          field1 type char10,
        end of ty_jtab.
populate the field twice..
   select ...
             field
             field
into table jtab
Now u can use the field field1 in the next select
select field1 field2
into table itab
from ztable1
for all entries in jtab
where field = jtab-field1.

SELECT with WHERE clause for MSAccess from JDBC

Hi,
I am new user of MSAccess.I am getting exception: Invalid user type when i was trying the following code:
String name1=nameTextfield.getText().trim();
String query="SELECT ID from Suppliers WHERE name=name1;"
Statement stmt=con.createStatement();
ResultSet rs=stmt.executeQuery(query);
while(rs.next())
String id1=rs.getInt(1);
System.out.println(id1);
nameTextField is JTextField in my GUI.
ID id auto field in table Suppliers.
I am using MSAccess 97.
I came to know that the JDBC SQL queries will be different for Access.
Any body help me how to write SELECT statement?
Thanks in advance,
Sai Ram

name or ID might be reserved words in access. Either change the name of the column or put [] around them. Also, you ar looking for a record where fields name and name1 are equal. You probably don't have a name1 field.
String name1=nameTextfield.getText().trim();
String query="SELECT [ID] from Suppliers WHERE [name]='"+name1+"';"
Pay attention to the single and double quotes I have.

Using select in where clause

I have 3 tables: contact2ext, contact2bnp, ext2bnp. contact2ext and contact2bnp both have a primary key called key. ext2bnp has 2 foreigns key, bnp and ext referencing these 2 primary keys.
I want to use select to do the following:
select nom from contact2ext where key = (select ext from ext2bnp where bnp=21);
any idea about how to do this ?
thanx
null

Hi,
The query you have placed is right.
Would appreciate if you give more clear idea about the data which wanted to be queried.
This is another form of the same query.
select nom from contact2ext where key IN(select ext from ext2bnp where bnp=21);
In which even if the internal query returns more than one record , it would work.
Best wishes.

JPA - Select with where clause

Hi
I have 2 classes:
-Class A
-Class B with a member which holds a reference to an object of Class A --> unidirectional one-to-one relation. The mapping is the following:
               <one-to-one name="a">
                    target-entity="domain.A" fetch="LAZY"
                    optional="false">
                    <join-column name="ID" table="A" />
               </one-to-one>
Now i want to find all objects of B which have a certain instance of A. I tried this, but it doesn't work:
     <named-query name="findBsByA">
          <query>select b from B b where b.a = ?1</query>

Any suggestions?

Yes you can, but you should use the language in the selection on MAKT:

INNER JOIN MAKT
ON MARAMATNR = MAKTMATNR

AND MARA~LVORM = SPACE
<b> AND MAKT~MAKTG LIKE '%DISCONTINUE%'
AND MAKT~SPRAS = SY-LANGU "or EN</b>
AND MVKE~VKORG = 'PUSA'

Slow Select Query - Where clause contains Seconday index field +other flds

Hi friends,
The below query is taking about an Hour to execute in production server when there are about 6 Million records in PLAF table. I have verified the trace in ST05 and the correct secondary index (Material Matnr + Plant Plwrk) is being selected.
SELECT plnum
             matnr
             plwrk
             pedtr

             pedtr IN s_date AND
             obart = '1'.
Will it be a good idea to have only MATNR (secondary index field) in the where condition of the select query and delete the internal table entries for the other where conditions ?
Edited by: Shruthi Seth on Feb 1, 2009 10:10 AM

Hello.
Creating a range r_mat = r_mat1 + r_mat2, I would do something like:
READ TABLE s_mrp1 TRANSPORTING NO FIELDS INDEX 1.
IF sy-subrc EQ 0.
SELECT plnum matnr plwrk pedtr dispo rsnum
    FROM plaf
    INTO wa_orders
   WHERE matnr IN r_mat
     AND pedtr IN s_date
     AND obart = '1'.
    IF wa_orders-matnr IN r_mat2.
      CHECK wa_orders-dispo IN s_mrp1.
    ENDIF.
    APPEND wa_orders TO it_orders.
ENDSELECT.
ELSE.
SELECT plnum matnr plwrk pedtr dispo rsnum
    FROM plaf
    INTO TABLE it_orders
   WHERE matnr IN r_mat1

Inserting Comments into Universe SELECT and WHERE clauses

I am converting an application from Crystal Reports to Business Objects. In conjunction with that, I am (manually) converting our Business View to a Universe. In Crystal we frequently documented our formulas using the Crystal Syntax "//...". Out of habit, I tried using the same syntax in the Universe... that didn't work. And poring through the Universe Designer's Guide and reviewing these forums didn't turn up anything either. Anyone else know how to do this? If it matters, we're reporting against an Oracle database.

Hi Scott,
if we are talking about plain SQL from ORACLE it's one of the inline comment characters (as /.../ )
documented in the Oracle manual.
see:
select 1 from dual /* my test */
union /* additional comments here
and here
and here
-- and here
select 2 from dual
BO may cover information in it's database specific documentation
