Where clause with a combination of And and Or statements - Basic question

Hi,
I have a where clause with a combination of And and Or statements... May I know which one would run first
Here is the sample
WHERE SITE_NAME = 'Q' AND ET_NAME IN ('12', '15') AND TEST_DATE > DATE OR SITE_NAME = 'E' AND ET_NAME IN ('19', '20')
can you please explain how this combination works
Thanks in advance

Hi,
This reminds me of a great story. It's so good, it probably didn't really happen, but it's so good, I'm going to repeat it anyway.
IBM once had an "executive apptitude test" that they would give to job applicants. There were some questions you might call general knowlege or trivia questions, and each question had a weight (for example, answering an unimportant queestion might score one point, an important question might be 5 points.) One of the questions was "What is the standard width of a mobile home?", and the weight of the question was -20: answering the question correctly did serious harm to your score. The reasoning was that the more you knew about mobile homes, the less likely you were to be their kind of executive.
Now, as to your question, the correct answer is: I don't know. I don't want to know. Mixing ANDs and ORs without grouping them in parentheses is a really bad idea. Even if you get it right, it's going to confuse the next person who has to look at that code. Use parentheses to make sure the code is doing what you want it to do.
If you really want to find out, it's documented in the SQL language manual. Look up "Operators, prcedence"
http://docs.oracle.com/cd/E11882_01/server.112/e26088/operators001.htm#sthref815
You can easily do an experiment, using scott.emp, or even dual, where
WHERE (x AND y)
OR      zproduces different results from
WHERE   x
AND     (y OR z)

Empty WHERE Clause with AND condition after

I have a question concerning a SQL query that I am using for a report. I have converted an old report to Crystal Reports 2008 and the resulting SQL query no longer works.
After the conversion all the inner joins that were previously used in the report were moved to the FROM clause.
My resulting WHERE clause is as follows:
WHERE AND
"TABLE"."TABLEKEY" IS NOT NULL
I get this error message:
ORA-00936 Missing expression
As you can see there WHERE clause has nothing before the AND condition because all the inner joins have moved to the FROM clause in the new version of Crystal Reports. I am fine with these inner joins moving but how do I take care of this empty condition.
Any help is appreciated.

How can I pass multiple condition in where clause with the join table?

Hi:
I need to collect several inputs at run time, and query the record according to the input.
How can I pass multiple conditions in where clause with the join table?
Thanks in advance for any help.
Regards,
TD

If you are using SQL-Plus or Reports you can use lexical parameters like:
SELECT * FROM emp &condition;
When you run the query it will ask for value of condition and you can enter what every you want. Here is a really fun query:
SELECT &columns FROM &tables &condition;
But if you are using Forms. Then you have to change the condition by SET_BLOCK_PROPERTY.
Best of luck!

Generate a where clause with outer join criteria condition: (+)=

Hi,
In my search page, I use Auto Customization Criteria mode, and I build where clause by using get Criteria():
public void initSrpQuery(Dictionary[] dic, String userName) {
int dicSize = dic.length;
StringBuffer whereClause = new StringBuffer(100);
Vector parameters = new Vector(5);
int clauseCount = 0;
int bindCount = 1;
for(int i=0; i < dicSize; i++){
String itemName = (String)(dic.get(OAViewObject.CRITERIA_ITEM_NAME));
Object value = dic[i].get(OAViewObject.CRITERIA_VALUE);
String joinCondition = (String)dic[i].get(OAViewObject.CRITERIA_JOIN_CONDITION);
String criteriaCondition = (String)dic[i].get(OAViewObject.CRITERIA_CONDITION);
String criteriaDataType = (String)dic[i].get(OAViewObject.CRITERIA_DATATYPE);
String viewAttributename = (String)dic[i].get(OAViewObject.CRITERIA_VIEW_ATTRIBUTE_NAME);
String columnName = findAttributeDef(viewAttributename).getColumnNameForQuery();
if((value != null) /*&& (!("".equals((String).trim())))*/){
if(clauseCount > 0){
whereClause.append(" AND ");
whereClause.append(columnName + " " + criteriaCondition + " :");
whereClause.append(++bindCount);
parameters.addElement(value);
clauseCount++;
If I want to generate following where clause:
select
,emp.name
,emp.email
,emp.salesrep_number
,comp.name
,gs.srp_goal_header_id
,gs.status_code
,gs.start_date
,gs.end_date
from g2c_goal_shr_emp_assignments_v emp
,jtf_rs_salesreps rs
,xxg2c_srp_goal_headers_all gs
,cn_comp_plans_all comp
where 1 = 1
and rs.salesrep_id = gs.salesrep_id (+)
and gs.comp_plan_id = comp.comp_plan_id (+)
and gs.period_year (+) = :1 -- :1 p_fiscal_year
How can I generate a where clause with outer join : gs.period_year (+) = :1 ? Will I get '(+)=' from get(OAViewObject.CRITERIA_CONDITION)?
thanks

Mysterious where clause with japanese

enviroment:
PL/SQL Develope, Version 7.1.0.1337, Windows XP Professional 5.1 Build 2600 (Service Pack 2)
Here is the problem, when i add a where clause with japanese, the data evaporated:
SQL> select * from ja_test;
EXECUTABLE_NAME DESCRIPTION
XX00MRP0411C 需要供給データ作成マネージャ
SQL> select * from ja_test j where j.description = '需要供給データ作成マネージャ';
EXECUTABLE_NAME DESCRIPTION
SQL>
thanks in advance!

Thanks for replies and Sorry for my rashness, maybe the following
scripts could explain the problem more well. I create a table named
ja_test with two fields(EXECUTABLE_NAME and DESCRIPTION), both of the
type is varchar2, and there is only one record in the table,
but the DESCRIPTION contains JAPANESE characters, when i use a where
clause like this "where j.executable_name = 'XX00MRP0411C';", everything
seems work fine, but when the where clase include JAPANESE characters
like this "j.description = '需要供給データ作成マネージャ';", even if
the "j.description" is copied form database, no records returned:
SQL> select * from ja_test j where j.executable_name = 'XX00MRP0411C';
EXECUTABLE_NAME DESCRIPTION
XX00MRP0411C 需要供給データ作成マネージャ
SQL> select * from ja_test j where j.description = '需要供給データ作成マネージャ';
EXECUTABLE_NAME DESCRIPTION

Where clause with time stamp

Hii,
I have an issue with using where clause with time stamp. My requirement is to
select * from driver_on_policy
where last_change_datetime = '2001-03-06 19:00:06'
date is in this form 6/3/2001 7:00:06 PM
thnks
sam

If you want to use '6/3/2001 7:00:06 PM', then
where last_change_datetime = to_timestamp('6/3/2001 7:00:06 PM','DD/MM/YYYY HH:MI:SS PM')If you can use a literal string in ANSI standard YYYY-MM-DD HH24:MI:SS format, then just
where last_change_datetime = timestamp '2001-03-06 19:00:06' (That 'DD/MM' might need to be switched around to 'MM/DD' if you are in America.)

"Invalid Column" on multiple where clauses with subqueries and cfqueryparam

I'm seeing a behavior in the coldfusion cfquery that I'd like to find an exmplanation for . I've got a query that does a subquery in the select portion and if I have multiple where lines, I get an "invalid column name" message for my second where clause, but only when I'm using cfqueryparam
For example on the following I get "Invalid column name 'position_id'"
SELECT   department_staff_tbl.*,
         (   SELECT   max(bookmark_id)
             FROM     bookmarked_items_tbl
             WHERE    item_id = department_staff_tbl.staff_id
         ) AS bookmark_id
FROM     department_staff_tbl
WHERE    department_id = <cfqueryparam value="#arguments.deptid#" cfsqltype="cf_sql_integer">
AND     position_id   = <cfqueryparam value="#arguments.posid#"   cfsqltype="cf_sql_integer">
AND     staff_id      = <cfqueryparam value="#arguments.staffid#" cfsqltype="cf_sql_integer">
If I change the order of my where clause so staff_id is first, then it tells me "department_id" is an invalid column.
If I only have one where clause, it works. (i.e. WHERE position_id = <cfqueryparam value="#arguments.posid#" cfsqltype="cf_sql_integer">).
If I remove the where clause from my subquery (WHERE     item_id = department_staff_tbl.staff_id) it works.
It also works if I remove the cfqueryparam from my where clause so that my query looks like this:
SELECT   department_staff_tbl.*,
         (   SELECT   max(bookmark_id)
             FROM     bookmarked_items_tbl
             WHERE    item_id = department_staff_tbl.staff_id
         ) AS bookmark_id
FROM     department_staff_tbl
WHERE    department_id = #arguments.deptid#
AND     position_id   = #arguments.posid#
AND     staff_id      = #arguments.staffid#
Any thoughts?

I see two tables. So can the server. So, use qualified column-names.
SELECT   department_staff_tbl.*,
         (   SELECT   max(bookmarked_items_tbl.bookmark_id)
             FROM     bookmarked_items_tbl
             WHERE    bookmarked_items_tbl.item_id = department_staff_tbl.staff_id
         ) AS bookmark_id
FROM     department_staff_tbl
WHERE    department_staff_tbl.department_id = <cfqueryparam value="#arguments.deptid#" cfsqltype="cf_sql_integer">
AND      department_staff_tbl.position_id   = <cfqueryparam value="#arguments.posid#"   cfsqltype="cf_sql_integer">
AND      department_staff_tbl.staff_id      = <cfqueryparam value="#arguments.staffid#" cfsqltype="cf_sql_integer">

Creating dynamic where clause with string delimiter " ; "

hi...
i need a solution for complex problem like, 1. start_date IN date,
end_date IN date,
shift_type IN varchar2
i will get shift_type as "first_shift" or "first_shift;second_shift" or "first_shift;second_shift;third_shift" ....etc any combination. where fist & second & third shits are nothing but 1 , 2 , 3. i need to find out data between start_date and end_date in combination of shifts ( may be 1;2 or 1;3 or 1;2;3 or 2;3 ...etc) . now i need to write this code in dynamic where clause ...i tried in different ways...but not succeeded. can anybody guide me step by step...or with script.
NOTE: there is a table called "shift" with data like
shift_type shift_mode
1 first_shift
2 second_shift
3 third_shift

Hi,
Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data.
If the question involves parameters, give a few different sets of parameters and the results you want for each set, given the same sample data.
It's unclear that you need dynamic SQL at all.
If shift_type is a variable, that can be either a single value or a ;-delimited list (such as '1;3'), you can compare that to a column called shift_column like this:
WHERE ';' || shift_type || ';' LIKE
'%;' || shift_column || ';%'No dynamic SQL or PL/SQL required.
If you really do want to use dynamic SQL, these two pages should gives you some ideas:

I created a custom database function xxpa_check_txnctl which takes project_id, task_id and expenditure type as parameters and returns "Y" if that expenditure type is valid or
returns "N" if it is not valid.
What I need to add to the where clause of the above query is
and *'Y' = ( select xxpa_check_txnctl(project_id,task_id,et.expenditure_type) from dual)* to the standard VO query so that only valid expenditure types will show up in the LOV for that
project/task combination.
I enabled the Debug Log from Diagnostics and able to see the values of project_id and task_id in the controller attached to the LOV (oracle.apps.icx.lov.webui.ExpenditureTypeLovCO) as shown
below. Please tell me how I can add the where condition to the custom controller .
I really appreciate your help.
Thanks in Advance,
Shree.

Hi, I will try to look into the issue. I have also done customizations like this in past.
To achieve this, we must read the Process request of CO properly and understand the places, where you have to make changes. In my case, I identify such places and also I couldn't extend the controller class. SO I took the code from standard CO, changed it at couple of places and created a class file with same code as standard CO but with changed at some places. After that I gave newly created CO name in personalization property, so that the page will follow newly created custom CO.
So I would suggest to read the CO properly, to understand which line is doing what......

Where clause with Bind Variable in ViewObject

As per recomendations from Jdev team they say that using Bind varialbles in where clause will improve the performance (Option 1) But it is causing us to create more view objects.
Example : Lets say we have a View Object EmpVO
Option 1:
ViewObject vo=context.getViewObject("EmpVO");
vo.setWhereClause("EMPNO=?");
vo.setWhereClauseParam(0,st);
(or)
Option 2:
vo.setWhereClause("EMPNO="+st);
If we want to use same View Object "EmpVO" in another Action Class
ViewObject vo1=context.getViewObject("EmpVO");
vo1.setWhereClause("DEPTNO=?");
vo1.setWhereClauseParam(0,str);
It this case it throws an error saying BIND VARIABLE already exits. So we have to make another View Object.
Where as if we did not use bind variable but used Option 2 approach the same view object can be used in multiple pages.(at the expense of performance as per Jdev team)
Are we doing something wrong here or are there other ways to use the same view object when using bind variable in where clause.
Thanks

I haven't been using BC4J for a while, but I seem to recall that the recommendations are that you don't set the where clause at runtime: You're supposed to define your view with the bind parameter already in it.
So you'd probably define an EmpsForEmpNoVO and type "EMPNO = ?" in the where box. (There are other ways of finding a single row/entity and one of those may well be more efficient. Perhaps a better example of where you might want a view of employees is WHERE DEPTNO = ?.)
IIRC, all instances of a particular type of view share the same definition, so you have to be careful if you alter that at runtime. However, I think everything's set up so that you can have many different (and separate) resultsets for a single view (instance) - meaning that it's possible to "run" a view for (e.g.) two different ids. (It's definitely possible to create two different instances of a view from its definition - and the resultsets will definitely be separate then. I think there's a "create" method on the application module; I remember that "find..." always returns the same instance of the view.)
Hope that's a push in the right direction (since no-one else had replied - and I hope not too much has changed since 9.0.3)....

Using where clause with like

Hi all,
im trying to set a block default where clause in the pre-query trigger of my block "customer_settlement" , to query the records that exist in a customers table like this, where the customer_name is variable based on the value entered by the user in enter-query mode before hitting the F8 key , the statement is :
set_block_property( 'customer_settlement' , default_where ,
' fk_cust_code in ( select customer_code from customers where customer_name like %' || :customer_settlement.customer_name ||'% )' );
the query doesnt work and giving me an error " unable to perform query" , notice that :customer_settlement.customer_name is an item in the block , the user change it and would like to query upon it , and its not a base table item on customer_settlement block its on customers table only . I tried all combinations of '%' and || but it seems that oracle can't see the value In the customer_name field.
any help is highly thanked.
im using Oracle form 9.0.4 and Oracle 10g Db.
Regards,
IKQ

Hi,
does this work ?
set_block_property( 'customer_settlement' , default_where ,
' fk_cust_code in ( select customer_code from customers where customer_name like '''%' || :customer_settlement.customer_name ||'%''' )' );

Prob. with where clause with rownum

hi
i have a table with the following columns
SQL> desc mark
Name Null? Type
STUDENTCODE NUMBER(3)
MARK1 NUMBER(2)
MARK2 NUMBER(3)
and here are the rows in it
SQL> select * from mark ;
STUDENTCODE MARK1 MARK2
1 20 40
2 70 80
3 80 90
4 90 99
12 13 35
5 90 80
6 78 87
i wanna sum mark1 and mark2 and list down the rows with the top 2 rows
i tried to first list down all the rows in the order of sum with the following stat.
SQL> select studentcode,mark1+mark2 from mark order by mark1+mark2 desc
STUDENTCODE MARK1+MARK2
4 189
3 170
5 170
6 165
2 150
1 60
12 48
it worked fine. but i used a where clause to get the first 2 rows and here is what i got.
SQL> select studentcode,mark1+mark2 from mark where rownum < 3 order by (mark1+mark2) desc
STUDENTCODE MARK1+MARK2
3 170
2 150
1 60
as You can see, i don't get the req. result.
how do i get the prob. solved ?

For Oracle versions prior to 8.1.5, you will have to create a view and then incorporate that view into your select statement.
create or replace view my_view
is
select studentcode, mark1 + mark2
from mark
order by mark1 + mark2 desc;
select *
from my_view
where rownum <= 2

Where Clause With Multiple Rows

I am tracking Objects called Incidents. Incidents can be made up of an undetermined number of questions and answers, such that my table structure to store these incidents looks as follows:
INCIDENT_ID     QUESTION_ID     ANSWER_ID
10001             49100         100 ("YES")
10001             49101         275 ("5 HOURS")
10002             49100         102 ("NO")
10002             49101         276 ("10 HOURS")I allow my users to enter complex queries, such as "give me all incidents where question 49100 equals YES AND question 49101 equals 5 or less, OR where 49100 equals NO and 49101 is greater than 5", etc...
My problem is how to handle these types of complex queries. Right now, I bring all of the rows into a Java object, and then I can analyze the results using Java (this works elegantly and allows me to have very complex formulas).
However, if I have to deal with millions of Incidents and Answers, bringing them all into Java seems to be very time consuming. I'd like to be able to handle everything in the database. Because I allow my users to enter the queries through a "query builder", I can't control how many conditions they might have. In other words, if I try to use inner queries in the WHERE clause, I may exceed limits.
It would be easiest if I could translate this vertical table into a temporary horizontal table, and then run my query on this horizontal table. My problem is that some of my questions have 1000s of answers (where they might be picking from a large select list), and therefore I can't do sums and counts on all the choices in separate columns. If I try a bit field for each column, once again I can run out of space because of the 1000s of possible answers.
Has anyone faced this issue before? What choices do I have to make this all work in the database without having to parse the results in Java?
Michael

I was under the impression that each medication uses a unique id itself (defined perhaps by the medical insurance industry) and that itemized lists contain that code. And thus the user can type in the code.
If so then one could handle the interface using both of the following methods.
- The user can type in the id (this is validated.)
- The user can push a button to bring up a dialog that provides the list and also provides an intelligent search option. (Or the id field can just be an aspect of the intelligent search.)
Even in a small doctor's office experienced users will probably know the common ids and it would be simpler for them to type that in. In a processing center this would be more important as the time to process each transaction directly impacts the bottom line. This becomes much more relevant when the users are paid bonuses based on how many transactions they process (and managers might get that as well.)
