Using ROWID in the WHERE clause of a SELECT statement

hi all,
my team is trying to select a value from a table using the rowid as the selection criterion
e.g. select column_name from table_name where rowid > 'AAA112BBBCCC12A'
this query does not appear to return accurate results e.g. it return rows instead of two. my questions are:
1. is this a legitimate approach?
2. should we convert the row id to varchar2? if so how should this be done?
thanks!

SQL> select rowid,ename
2 from emp;

7 rows selected.1) using rowid to access a record is the quickest way so it is legitimate
however using > has no real purpose as you point out you cannot get any meaningful results returned.
2) No real need to convert however beware storing values in tables as Oracle does not guarantee to preserve the format in different versions so upgrading from 9i to 10g would invalidate your data.

Values from a Multi-Select in the where clause of a Select statement

I have a web page that solicits query parameters from the user.
The selections that the user makes will populate the WHERE clause of a Select statement.
One of the controls on the page is a multi-select control.
When this page posts, I would like to execute a Select statement wherein the selected values from this control appear in the .. Column IN ( <list here> ) portion of the WHERE clause.
This is an extremely common scenario, but I cannot seem to locate a how-to or message thread that addresses this specific case.
I have an idea that it may involve dynamic SQL or Execute Immediate, but cannot seem to pin down the answer.
Any help would be greatly appreciated!

Using if logic in the where clause of a select statement

I have a select clause. And in the select clause there is a variable all_off_trt that can be 'Y' or 'N'.
In the where clause I want to make it so that if a form variable is checked and all_off_trt is 'Y' then
exclude it else if the form variable isn't checked then select it no matter what all_off_trt is.
Is there any way to include either and if statement or a case statement within the where clause to acheive this? If not is there another way of doing it?
Basically I am looking for a case statement like this
case
when all_off_trt = 'Y' and mail_para.code = 'Y' then false
else true
end

Ok, so that really doesn't solve my problem. I have 3 different fields that I need to do that with. Each combining in a select statement to print an email list, as well as other thing limiting the where clause.
This is currently what I have, tested and working 100%.
cursor email_cur is
select unique p.email,s.all_off_trt,s.all_deceased,s.no_enroll
from participant p, trialcom t, ethics s
where p.status='A'
and p.surname=t.surname
and p.initials=t.initials
and s.trial_cd = t.tricom
and s.centre = t.centre
and p.email is not null
and (t.centre in (select code from mail_parameters where user_name=user and mail_para='CENTRE')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='CENTRE'))
and (t.tricom in (select code from mail_parameters where user_name=user and mail_para='TRIAL')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='TRIAL'))
and (t.role in (select code from mail_parameters where user_name=user and mail_para='ROLE')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='ROLE'))
and (p.country in (select code from mail_parameters where user_name=user and mail_para='COUNTRY')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='COUNTRY'))
and (t.represent in (select code from mail_parameters where user_name=user and mail_para='REPRESENT')
or 'XX' in (select code from mail_parameters where user_name=user and mail_para='REPRESENT'));
This is in a program unit that runs when a button is clicked. At the end of that I need to add on the 3 case statements that help further narrow down the selection of emails to be printed. Then it prints the emails selected from this statement into a file. So it has to be done right in the select statement. The three table variables are the all_off_trt, all_deceased, and no_enroll. The form has 3 checkboxes. One for each, that when checked (giving the variable associated with the checkboxes a value of 'Y') excludes all emails that have a 'Y' in the coresponding table variable.

Can I use SYSDATE in the WHERE clause to limit the date range of a query

Hi,
Basicaly the subject title(Can I use SYSDATE in the WHERE clause to limit the date range of a query) is my question.
Is this possible and if it is how can I use it. Do I need to join the table to DUAL?
Thanks in advance.
Stelios

As previous poster said, no data is null value, no value. If you want something, you have nvl function to replace null value by an other more significative value in your query.<br>

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

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 ?

Parsing an input parameter for the where clause or record select value

In my limited CR experience, I've always used a command database connection so that I can write my own SQL. However, now I have to parse a pipe delimited parameter to get my value for the where clause, so I'm selecting several tables and joining them through the Database Expert Links tab. All works fine, but after doing that and then parsing the parameter with the below formula in the Select Expert, I notice that there is no where clause in the SQL query, and although the report eventually displays the proper values, it runs through thousands of records first. Here is my Select Expert - Record formula:
StringVar array Parm1;
Parm1 := Split({?DATA_AREA}, "|");
{SO_ORDERS.CASE_ID} = Parm1[2]
If I change "Parm1[2]" on the last line to a valid Case ID, then there is a where clause in the SQL and the report generates immediately.
It seems like the record select formula is applied AFTER all of the records (without a where clause) are searched when I use the parsed parameter value, but when I hard code a valid value, it places that into the where clause BEFORE the sql is executed. Is there a way to get the parameter parsed first and then use that parsed value in the SQL where clause?
Thanks.
Bill

Yes crystal will run the query first to get 100% data and then applies record selection condition. To increase the performance you need to pass the where condition at the command level instead of report level. So you need to create a report using add command like this
select * from tablename where field={?Parameter}
{?Parameter} is a command level parameter.
Now insert this report as a subreport in another report which has no connection but has a parameter
{?DATA_AREA} and create a formula like this in the main report
Split({?DATA_AREA}, "|")[2]
Now right click on the subreport and go to change subreport links and add this formula from main report and link this to sub report parameter {?Parameter} without linking any database field from the subreport.
Now your subreport runs with the where clause to get the data.

Raghavendra

How to use DATE in the where clause

I need to select list of records from a table where available date is greater than or equal to current date. Below is the table structure and
select query used to get the list of records
CREATE TABLE TEMP (ITEM_ID NUMBER(20),ITEM_NAME VARCHAR2(100),CREATION_DATE DATE,AVAILABLE_DATE DATE);
INSERT INTO TEMP (ITEM_ID,ITEM_NAME,CREATION_DATE,AVAILABLE_DATE) VALUES(1,'ITEM1',SYSDATE,SYSDATE);
INSERT INTO TEMP (ITEM_ID,ITEM_NAME,CREATION_DATE,AVAILABLE_DATE) VALUES(2,'ITEM2',SYSDATE,SYSDATE+10);
INSERT INTO TEMP (ITEM_ID,ITEM_NAME,CREATION_DATE,AVAILABLE_DATE) VALUES(3,'ITEM3',SYSDATE,SYSDATE-10);
INSERT INTO TEMP (ITEM_ID,ITEM_NAME,CREATION_DATE,AVAILABLE_DATE) VALUES(4,'ITEM4',SYSDATE,SYSDATE);
INSERT INTO TEMP (ITEM_ID,ITEM_NAME,CREATION_DATE,AVAILABLE_DATE) VALUES(5,'ITEM5',SYSDATE,SYSDATE+5);
SELECT ITEM_NAME, available_date FROM TEMP WHERE available_date > SYSDATE OR available_date LIKE SYSDATE;I am getting the expected records but i am not able to find a condition where i can use *>=* for date data type, a query like the below one is

Both operands to LIKE are supposed to be strings. Don't try to use a DATE, such as SYSDATE, with LIKE.
I am getting the expected records but i am not able to find a condition where i can use *>=* for date data type, a query like the below one is
not returning expected records
SELECT ITEM_NAME, available_date FROM TEMP WHERE available_date >= SYSDATE ;
It's returning the results I expect.
If you'd say what results you were expecting, someone could help you wite a query to get them.
Assuming 1 second elapses between the time 'ITEM4' is inserted and the time the 2nd query is run, then, at run-time, available_date will be 1 second less than SYSDATE, so it should not be included.
If you want to find rows that are on the same calendar day as SYSDATE, or later, then use
WHERE available_date >= TRUNC (SYSDATE)

How can define an outer join in the where clause of a flowr statement?

What you could do is use query within an XMLTable syntax. Via the COLUMNS parameter you then pass the "column" as XMLType to the following XMLtable statement.
little bit like the following
select hdjfdf
from xmltable
   ({xquery}
    PASSING
    COLUMNS xmlfrag xmltype path 'xxx'
   ) a
, xmltable
   ({the other stuff you need}
    PASSING a.xmlfrag
   ...etc
...etc                 I guess something simular can be done via XQuery straight away as well

Using multiple dates in WHERE clause

I have a multiple select box in a form. I am trying to select
records in SQL using the list that this form field produces. They
are dateTime values. How do I use this list in the WHERE clause of
my select statement?

Man, I really hate posting anywhere near Dan - I've been
watching his mastery for years. (Talk about the big leagues) But
here goes anyway...
I've gotten my little behind kicked by more than a view date
issues, and I have basically gotten away from exact matches (unless
you really need them).
I'd probably do something like this:
SELECT field1,field2...
WHERE datetime_column_in_db > (OR LTE,OR GT/LT)
'#datetimeformatyoulike(form.datetimevalue1)#
Basically, finding records in RELATION to the form's datetime
value has always been much easier for me.
And God (and Dan) have mercy on my soul...

Using CLOB datatypes in WHERE clause

Hi All,
I have a table with two columns as CLOB datatype. I'm using Oracle 8i Enterprise Edition. I can do a query, insert, update and even delete the data in the CLOB field using Oracle's SQL Plus.
What I want is to do a search on those fields.. that is include that field in a WHERE clause. I'm using this datatype to store large number of data.
I'd like to see this query working...
SELECT * FROM MyTable WHERE CLOBFLD LIKE 'Something...';
Now this query doesn't work. It returns: 'Inconsistent datatype' near the word CLOBFLD.
Please Help me out.
Regards,
Gopi
null

I presume you want to query based on the contents of the CLOB, right ? If that is true, then you have to create a text index, using Oracle Context and then use "Contains" in the where clause to query. Hope this helps.

Use "ListContains' in a WHERE clause

I believe I have a syntax problem and could you some help.
First, I have a field in an Access DB called 'degree" that conatins
a list of numbers. This list can be any combination of the numbers
4 through 32. On my search page I have a selection box in a form to
select a value of the degree to search for. The variable passed
from the form is called "degreeValue". I have a component that lets
me build my WHERE clause using several seach criteria. It functions
perfectly prior to adding the search for "degree". I attempted to
use "ListContains" in the WHERE clause using "degree" as the name
of my list and "degreeValue" as my substring to search for. The
error I get says that "variable degree is undefined". I am
attaching the full code of the compoanent so you can see it. Again,
it works if you take out the subclause build for "degree".

I understand what you are saying and in other situations have
done my tables that way. I didn't this time because this is one of
those... "add it later" kind of things. Yes, the field does look
like "1,2,3,4,etc.." The inventory a couple thousand items each
with a number (catno). As you obviously noticed the inventory table
houses most of the data for the items. The "degree" field in the
past was only used to populate a series of checkboxes and was not
searchable, thus a list was used.
With a possibility of 29 values for "degree" and a
possiblility of over 2,000 inventory items you can see a newly
created table might become quite large. It would be nice if I could
use the current structure.
You are absolutely correct saying the design should be
different. Thank you for your quick reply and good information.
