Where clause question

Hi Experts,
We have a typical requirement for including the where clause dynamically. Here is the Scenario:
We will be getting the Where Clause as a string parameter value from reporting framework. This needs to be appended in Crystal Reports with Select Clause.
Here is an example. We will be getting the Where parameter value as
clnt_id=1001 and acct_no=232 and cust='XYZ'
This will be passed as a single string to CR which needs to act as Where Clause while the CR query hits database.
Not sure how to implement this. Any suggestions will be of great help.
Thanks
Naresh

As far as I'm aware, there are no other solutions, unless you want to parse the Where clause string in Crystal and code the possibilities. This might be reasonable if there are only a couple of fields that possibly would be used in the where clause of any given report, but tedious and slow if there are hundreds. Report performance will suffer in any case because the database will not be performing the Where clause, so more data will be passed back to Crystal which it will have to determine needs to be dropped.
I don't know how many existing reports you're dealing with, but it might not be overly time consuming to change the reports to be based on an SQL Command. After all, Crystal can give you the SQL that it intends to use when a report is defined based on tables and views... IMHO, I see the benefit of using an SQL Command and have the database do the Where clause worth while in this case...

Where-Clause-Question using "sets of values"

Hello,
I'm using 10gR2
Is it possible to filter rows by using sets of values in the where-clause?
E.g. like:
SELECT a, b, c
FROM mytable
WHERE (b,c) IN
      (3,4),
      (6,7),
      (9,1),
      (0,2)
    )...should only retrieve rows from mytable with the sets (pairs) of above list

Here is a link to the docs: [Expression Lists|http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/expressions014.htm#i1033664]
!http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/img/expression_list.gif!
The number of expressions in each set must match the number of expressions before the operator in the comparison condition or before the IN keyword in the membership condition.

WHERE clause order ox execution question

I dont understand order of execution of a WHERE clause, using a complex database
I want to write a SELECT statement with the following condition
... WHERE ( branch = 'main' ) AND ( type = 1 ) OR ( charge -1 AND charge = 2 )
My question is
<1> Can yoyu use parenthesis inside of a WHERE clause
<2> How would you write such a clause as above if you can not use parenthesis
Thanks

Just to echo what everyone else is saying, of course parentheses are syntactically valid and can make a difference to the logic. In you example though,
WHERE ( branch = 'main' ) AND ( type = 1 ) OR ( charge {noformat}<{noformat}> -1 AND charge <= 2 )is the same thing as
WHERE ( branch = 'main' AND type = 1 ) OR ( charge {noformat}<{noformat}> -1 AND charge <= 2 )and even
WHERE branch = 'main' AND type = 1 OR charge {noformat}<{noformat}> -1 AND charge <= 2because AND takes precedence over OR. You can think of it as a "stronger" operator.
However I would not use the last version because it's ambiguous to anyone reading it, and code like that can easily hide bugs. I would also not use the first version because all those redundant brackets are just confusing, making it almost as hard to read (and therefore prone to bugs) as the last version.
btw I've changed your example because I know this forum can swallow *{noformat}<{noformat}>* (I've used {noformat} tags to preserve it).
I'm not sure if any of this affects order of execution (and if it does, your Oracle version will make a difference).

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)

Nested IF Statement in WHERE clause...

Here is a really abridged sample of my package. I need to ensure that if a salesrep has a status of 'I' (for "inactive") that the next salesrep with a status of 'A' (for "active") will be selected in its place.
Should I include a nested loop within the WHERE clause? Any tips on how I should go about it? I'm a newbie...thanks for the help..
SELECT rsa.name rep_name
,rsa.attribute7 rep_phone
,rsa.arrtibute8 rep_ext
FROM ra_salesreps_all rsa
WHERE rsa.status(+) = 'A'

I'm assuming that this is part of your procedure within a package.....
You must be writing a CURSOR here....
Cursors are memory locations that can store retrieved rows and then process them one by one.
create or replace procedure my_proc
(<example_var> IN|OUT TYPE)
IS
cursor my_cursor IS
select <the fields I want>
from <sales type table>
where <my value> = 'A';
BEGIN
<how to process the cursor>
You can write the cursor process 2 ways:
1) FOR x in <name_of_cursor> LOOP
(This does whatever to the data for every record already selected by the cursor)
2) OPEN....FETCH....CLOSE
This is only scratching the surface of cursors...you need to read about these for what you are doing.
Question though...is this something you need to run for a SQL process in Oracle Applications??....if so you don't need to write a package/ procedure. You can write a cursor and load it as type SQL*PLUS, and it will run for you.

Re: [iPlanet-JATO] How to make an OR in the WHERE clause of a SELECT

Harry,
If you get a reference to your model, you can set the
whereClauseOverride with exactly the string you want to use. Keep in
mind that you are dealing with a the raw SQL where clause, therefore,
you must use the actual table column names and not the model's logical
field names as they could be different.
QueryModelBase queryModel = (QueryModelBase)getModel(PersonModel.class);
// you must add the "WHERE" as well
String whereClause = "WHERE firstName LIKE '%max' OR lastName LIKE '%max%'";
queryModel.setWhereClauseOverride(whereClause);
Keep in mind that this will override all where criteria: static and
dynamic where criteria. Static criteria can be declared in your model
class: setStaticWhereCriteriaString(STATIC_WHERE_CRITERIA).
You could optionally get the entire SQL statement and replace the
__WHERE__ token yourself with a string replace technique. In fact, if
you want to add an ORDER BY, you will need to get the SQL and append to
the end.
queryModel.getSelectSQL();
Hope this helps. Let me know if you have any questions

Rewritten your query wuth tags as well

        "P_CIRCUITS_FIBER"."PORTS_2",
        CASE WHEN CPORT.ID = (select REGEXP_SUBSTR(ports_1,'[^,]+',1,1) from p_circuits_fiber)
             THEN "CPORT"."PORT_NO" END PORT_NO_1,
        CASE WHEN CPORT.ID = (select REGEXP_SUBSTR(ports_2,'[^,]+',1,1) from p_circuits_fiber)
             THEN "CPORT"."PORT_NO" END PORT_NO_2
from    "CPORT",
        "P_CIRCUITS_FIBER"
where   p_circuits_fiber.fiber_id = :P4000_CIRCUIT_NO
and     (select REGEXP_SUBSTR(ports_1,'[^,]+',1,1) from p_circuits_fiber) = "CPORT"."PORT_NO" "PORT_NO_1"
and     (select REGEXP_SUBSTR(ports_2,'[^,]+',1,1) from p_circuits_fiber) = "CPORT"."PORT_NO" "PORT_NO_2"{code}
Now we can see two columns references which should not be there.
I even not sure to understand why those two conditions are in the WHERE clause. But for sure, CPORT.ID cannot be equal to two values unless they are same.
Is there only one row in p_circuits_fiber ?

Be careful; post the code you're actually running.

My questions:
1) Why isn't the index t_indx used in Execution plan 1?To use an index, the indexed column must stand alone as one of the operands. If you had a function-based index on TRUNC (fdate), then it might be used in Query 1, because the left operand of = is TRUNC (fdate).
2) From the execution plan, I see that query 2 & 3 is better than query 1. I do not see any difference between execution plan 2 & 3. Which one is better?That depends on what you mean by "better".
If "better" means faster, you've already shown that one is about as good as the other.
Queries 2 and 3 are doing different things. Assuming the table stays the same, Query 2 may give different results every day, but the results of Query 3 will never change.
For clarity, I prefer:
WHERE fdate >= TRUNC (SYSDATE)
AND fdate < TRUNC (SYSDATE) + 1(or replace SYSDATE with a TO_DATE expression, depending on the requirements).
3) I read somewhere - "Always check the Access Predicates and Filter Predicates of Explain Plan carefully to determine which columns are contributing to a Range Scan and which columns are merely filtering the returned rows. Be sceptical if the same clause is shown in both."

How can you add a where clause using "OR" with applied ViewCriteria?

[JDeveloper 10.1.3 SU4]
[JHeadstart 10.1.3 build 78]
I am using JHeadstart, but have a question probably more in the ADF area. On the JHeadstart forum I asked:
"I am overriding JhsApplicationModule's advancedSearch in order to be able to search in childtables. I created transient attributes, display those in advanced search and in the overridden method I check if any of these are filled by the user and create a where clause like 'EXISTS (SELECT 1 FROM <childtable> WHERE <column in childtable> = <column in EO's table> AND <another column in childtable> LIKE '<value supplied by user>)'. I add this whereclause using ViewObject.setWhereClause.
So far so good and it works. However, if the user selects 'Result matches any criteria', combining setWhereClause and the normal advancedSearch QueryByExample implementation using ViewCriteriaRow do not provide the desired result, since the ViewCriteria and the setWhereClause are AND-ed together, which is fine if the user selects the (default) "Results match all criteria" (everything is AND-ed) but not the "Result matches any criteria", since then every criterium is OR-ed together, except for the setwhereclause criteria and the set of ViewCriteriaRows, they are AND-ed.
I looked if I could specify that a WhereClause will be OR-ed to existing applied ViewCriteria, but no luck. Do I have to rewrite also advancedSearch's ViewCriteria implementation and write an entire setWhereClause implementation to be able to "OR" every criterium? Or any other suggestions? Can I look at the entire Where clause and rewrite it (after applyCriteria and setWhereClause are called on the VO)?
Toine"
Sandra Muller (JHeadstart Team) told me today: "This sounds like a JDeveloper/ADF issue that is not related to JHeadstart. The question is: how can you add a where clause using "OR" if there are already one or more ViewCriteria applied?
To simplify the test case, you could create a simple ADF BC test client class in a test Model project without JHeadstart (in the test class, use bc4jclient + Ctrl-Enter), in which you first apply a few ViewCriteriaRows to a View Object and also add a where clause.
Can you please log a TAR at MetaLink ( http://metalink.oracle.com/ ), or ask this question at the JDeveloper forum at http://otn.oracle.com/discussionforums/jdev.html ? (This what I am doing now ;-))
Thanks,

Anyone knowing the answer or am I asking for an enhancement?

Hi,
Can you SET your whereclause as follows ?
('Y' = <isAnd>
and EXISTS (SELECT 1 FROM <childtable> WHERE <column in childtable> = <column in EO's table> AND <another column in childtable> LIKE '<value supplied by user>))
OR ('N' = <isAnd>

SQL Strings in Where Clause - single quotes issue

All,
Im having issues related to SQL String literals when trying to deploy to flash. The complication works fine but I then get a message (see below) stating that a ; is missing. The SQL query and the iview runs fine when we use numeric values or do not apply a where clause on the table.
I am using Visual Composer that has been packaged with NW2004sSP7_Preview
VC & Flex Version: 645.7.0.3
The Error message is get is;
Error in executing a process for Flex compilation, Error 1033: ';' expected

When I goto the deployment file it has the below line;

It seems that the parser for the flash deployment is prematurely finishing the parse when it hits the single quotation in the SQL string!
We had a similar error where if we had a carriage return in the SQL (e.g. between the from & the where clause) then the deployment parser was stating that the line finished prematurely. In the deployment file the carriage return forced a new line thus making the message incomplete. Removing the carriage return resolve that issue
The SQL Preview in the SQL Editor within VC works fine with the string literals in the where clause.
The functionality compiles & deploys in web dynpro however it does not return the results to the table
Questions
1:> Has anyone successfully used flash with string literals in the SQL where clause or had seen this issue in the past?
2:> Is there a setting to get the SQL working on Web dynpro for the information to be returned that I may have missed?
Any assistance would be greatly appreciated.
Best Regards,
Ian.

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.

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!

It has got CTE ( common table expression ) which is referred 2 time within SP. This CTE is very big and fetches records from several tables without where clause. This causes several records to be fetched from DB and then needed processing. This stored procedure is running in pre prod server which has 6gb of memory and built on virtual server and the same proc ran good in prod server which has 64gb of ram with physical server (40sec). and the execution time in pre prod is 1min 9seconds which needs to be reduced upto 10secs or so will be the solution. and also the exec time differs from time to time. sometimes it is 50sec and sometimes 1min 9seconds..
Pl provide what is the best option/practise to use where clause to filter the records and tool to be used to tune the procedure like execution plan, sql profiler?? I am using toad for sqlserver 5.7. Here I see execution plan tab available while running the SP. but when i run it throws an error. Pl help and provide inputs.
Thanks,
Viji

You've asked a SQL Server question in an Oracle forum. I'm expecting that this will get locked momentarily when a moderator drops by.
Microsoft has its own forums for SQL Server, you'll have more luck over there. When you do go there, however, you'll almost certainly get more help if you can pare down the problem (or at least better explain what your code is doing). Very few people want to read hundreds of lines of code, guess what's it's supposed to do, guess what is slow, and then guess at how to improve things. Posting query plans, the results of profiling, cutting out any code that is unnecessary to the performance problem, etc. will get you much better answers.

PL/SQL Evaluation problem of where clause in case of NUMBER column type

I found the following problem in Oracle® Database 2 Day Developer's Guide 11g Release 1 (11.1) B28843-04:
The sole parameter of function eval_frequency is employee_id IN employees.employee_id%TYPE.
An ORA-01422 exception occurs when the execution reaches the following select command
SELECT e.hire_date
INTO hire_date
FROM employees e
WHERE employee_id= e.employee_id;
A possible cause of the error is that the type of employee_id is NUMBER while the employees.employee_id is NUMBER(6,0) . The result of the selection is the same as there were no WHERE clause at all.
Everything worked fine, when I declared a temporary variable of NUMBER(6,0) for storing the actual parameter of function and used this variable in the where clause, but I consider this "solution" as being no solution.
It is pointless to use %TYPE parameter of a function for flexibility if I must degrade this flexibility by a fixed declaration of a temporary variable of the same type as the column in question.
What is wrong?
The Developer'Guide I used, the Oracle Sql Developer I used or the PL/SQL version ?

Hi,
Welcome to the forum!

The variable employee_id is defined as having the exact same type as the eponymous column. Even if it didn't, I believe Oracle will always implicity convert between datatypes when possible, rounding if necessary. That may cause errors, but it isn't causing this error.
No, the error has nothing to do with the data type. It has to do with the ambiguity of employee_id: is it a column, or is it a variable?
The default is that it means the column name, so
WHERE   employee_id = e.employee_idis equivalent to saying
WHERE   e.employee_id = e.employee_idwhich isn't quite the same thing as not having a WHERE clause; rows with NULL employee_id would still be excluded, if there were any.
I think it's best not to use variable names that are the same as column names. You could call the variable v_employee_id, or, since it's an IN-argument, in_employee_id.
If you must use a variable that can be mistaken for a column, then qulaify it with the name of the procedure, like this:
WHERE   eval_frequency.employee_id = e.employee_id
Everything worked fine, when I declared a temporary variable of NUMBER(6,0) for storing the actual parameter of function That makes sens. You probably gave that variable a name that couldn't be mistaken for a column in the table.

Strange errors when using user defined function in where clause

Hello,
I am having trouble with a function that, when used in the where clause of a select will cause an error if the first column selected is of type INTEGER. Not sure whether I am doing something wrong or whether this is a bug.
Here is a very simple test case:
create table test(
col1 integer not null,
col2 varchar(20) ascii default ''
insert into test values(1,'2011-03-15 05:00:00')
insert into test values(2,'2011-03-15 07:00:00')
CREATE FUNCTION BTR_TAG RETURNS VARCHAR AS
VAR ret VARCHAR(20);
SET ret='2011-03-15 06:00:00';
RETURN ret;
Select * from test where col2 >= BTR_TAG()
Select col1,col2 from test where col2 >= BTR_TAG()
=> Error in assignment;-3016 POS(1) Invalid numeric constant
Select '',* from test where col2 >= BTR_TAG()
Select col2,col1 from test where col2 >= BTR_TAG()
=> works as it should
MaxDB V 7.7.07.16 running on Windows Server 2003
I can replicated the test case above with Sql Studio and other ODBC based tools.
Thanks in advance,

Using user defined function in where clause

Hi,
I have defined function to get maximum date before passed date on the table 'A' and I'm using the same function to get details on that date from the same table 'A' in where clause.
for ex:
SELECT x,y,z
FROM A
WHREE a.date = max_date;
But on one database instance it is running fine and on other it is going in a infinite loop.
Pls help me out
Thanks in advance,
Prashant
