Using to_number in a where clause

Consider a table T that has 2 columns, of type VARCHAR2. Consider the following tables values
Col1 Col2
A        1
A        2
B        X
B        Y
will the below query always work:
select * from T where col1 = 'A' and to_number(col2) between 1 and 2
Would oracle apply the where clause criteria as defined in the SQL from left to right?
Thanks

I did not understand your query but have you tried using the HAVING clause?
HAVING clause allows you to use a "where" like condition for your groupings.
See http://www.techonthenet.com/sql/having.php for some examples.

How can we use DECODE function in where clause.

Hi Guys,
I have to use DECODE function in where clause.
like below
select * from tab1,tab2
where a.tab1 = b.tab2
and decode(code, 'a','approved')
in this manner its not accepting?
Can any one help me on this or any other aproach?
Thanks

I am looking for to decode the actual db value something in different for my report.
like if A then Accepted
elseif R then Rejected
elseif D then Denied
these conditions I have to check in where clause.

what are you trying to do?
may be you are looking for

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.

How to use alias name in where clause

Hello,
DECODE (item.inv_type,'OT', (DECODE (item.attribute2, 'STONE', 0, xfer.release_quantity1 * xfer.attribute10)
'FG', (xfer.release_quantity1 * xfer.attribute10)
) matl_val
In the above code matl_val is alias name i need to use that one in where clause as
where matl_val > 0
is this possible or anyother way can anyone help me.

But the point is as you haven't read the documentation you may miss some valuable points about alias and will soon end with another problem.
>
Specify an alias for the column expression. Oracle Database will use this alias in the column heading of the result set. The AS keyword is optional. The alias effectively renames the select list item for the duration of the query. The alias can be used in the order_by_clause but not other clauses in the query.

How to use CASE stmt in Where clause

How to use CASE stmt in WHERE clause?. I need the code. Please send me as early as possible..........

Hi,

Hi,
How to use CASE stmt in WHERE clause?. There's no difference between how a CASE expression is used in a WHERE clause, and how it is used in any other clause. CASE ... END always returns a single scalar value, and it can be used almost anywere a single scalar expression (such as a column, a literal, a single-row function, a + operation, ...) can be used.
CASE expressions aren't needed in WHERE clauses very much. The reason CASE expressions are so useful is that they allow you to do IF-THEN-ELSE logic anywhere in SQL. The WHERE clause already allows you to do IF-THEN-ELSE logic, usually in a more convenient way.
I need the code.So do the peple who want t help you. Post a query where you'd like to use a CASE expression in the WHERE clause. Post CREATE TABLE and INSERT statements for any tables used unless they are commonly available, such as scott.emp). Also, post the results you want from that sample data, and explain how you get those resuts from that data.
See the forum FAQ {message:id=9360002}
Please send me as early as possible..........As mentioned bfore, that's rude. It's also self-defeating. Nobody will refuse to help you because you don't appear pushy enough, but some people will refuse to help you if you appear too pushy.

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>

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.

Is it possible to use LONG columns in WHERE clause or ORDER BY?

Is it possible to use LONG columns in WHERE clause or ORDER BY?

Hi,
LONG data type is deprecated, maybe could you change your column type to LOB ?
Nonetheless below is a workaround which may fit your needs if forced to use LONG.
It uses a function which returns you a CLOB. It allows you to use the converted "LONG" column in a WHERE clause.
Then if you want to order by you have to convert the CLOB to a VARCHAR using DBMS_LOB.SUBSTR.

No output for XML Publisher Report using CASE/DECODE in Where Clause

Hi,
I've a business requirement to modify an existing report which has two input parameters,
-> p_statcode (Closed Status) which can have values 'Y' or 'N'
-> p_overdue (Overdue Flag) which can have values 'Y' or 'N'
The Overdue Flag is an evaluated column having values of Y/N and it is evaluated as follows,
ONTF_MOD_VAL(NVL (
                                     (TRUNC (SYSDATE)
                                      - (TO_DATE (oe_order_lines.attribute18,
                                                  'DD-MON-RRRR')
                                         + TO_NUMBER (fnd_lookup_values.meaning))),
                                     0
                        overdue_flagThe user requirement now is they needs to be a third option for parameter p_overdue called ALL,
passing which the output should include records having
p_statcode is Y ELSE p_statcode is N AND p_overdue is Y OR p_overdue is N
In other words records having both Y and N vlaues for Overdue Flag have to be returned irrespective of the value given to Closed Status.
Original where clause in the Data Definition file is as follows,
WHERE Closed_Status = nvl(:p_statcode,Closed_Status)
                   AND overdue_flag = nvl(:p_overdue,overdue_flag)My modified code is as follows,
WHERE   Closed_Status = NVL (:p_statcode, Closed_Status)
         AND overdue_flag = (CASE
         WHEN :p_overdue = 'Y' THEN 'Y'
         WHEN :p_overdue = 'N' THEN 'N'
         ELSE overdue_flag
         END)
OR
WHERE   Closed_Status = NVL (:p_statcode, Closed_Status)
         AND overdue_flag = DECODE (:p_overdue, 'Y', 'Y', 'N', 'N',overdue_flag)Both approaches have the same problem.
The output is in EXCEL format. The modified query works fine for p_overdue as Y or N but when p_overdue is passed as ALL it returns an empty EXCEL sheet with just the report output column headers.
Any help as to why this is the case ?? What is wrong in my approach ?
Regards,
Vishal

not clear about p_overdue = ALL
which values needed for p_overdue = ALL ?
try smth like
WHERE   Closed_Status = NVL (:p_statcode, Closed_Status)
AND (
   overdue_flag = DECODE (:p_overdue, 'Y', 'Y', 'N', 'N',overdue_flag) and :p_overdue != 'ALL'
   or
:p_overdue = 'ALL' and (overdue_flag = 'Y' or overdue_flag = 'N')
)for overdue_flag which has more then 'Y', 'N' values
if overdue_flag only in ('Y','N') then
WHERE   Closed_Status = NVL (:p_statcode, Closed_Status)
AND (
   overdue_flag = DECODE (:p_overdue, 'Y', 'Y', 'N', 'N',overdue_flag) and :p_overdue != 'ALL'
   or
:p_overdue = 'ALL'
)

Using regexp_instr in a where clause - invalid relational operator

Whey I try to run this query in TOAD I get an ORA-00920: invalid relational operator error. It's part of a 10g stored procedure. When I highlight it and run it it prompts me for the missing values and then the error pops up. The AND in line 4 is highlighted.
select CRIME_CLASSIFICATION_ID, crime_type, nvl(count(CRIME_CLASSIFICATION_ID),0) as CRIMECNT
From vaps.vw_offenses
    where regexp_instr(valoc,to_char(location_id))
        AND ( fromdate is null or
         offense_date between to_date(fromdate, 'mm/dd/yyyy') AND to_date(todate,'mm/dd/yyyy')
group by crime_classification_id, crime_type

Hi,
Review what REGEXP_INSTR does: it returns a NUMBER.
Your WHERE clause couldn't make any sense if you used any other kind of NUMBER expression in that place, e.g. a NUMBER literal such as 12:
select CRIME_CLASSIFICATION_ID, crime_type, nvl(count(CRIME_CLASSIFICATION_ID),0) as CRIMECNT
From vaps.vw_offenses
    where 12     -- This is obviously wrong
        AND ( fromdate is null or
         offense_date between to_date(fromdate, 'mm/dd/yyyy') AND to_date(todate,'mm/dd/yyyy')
group by crime_classification_id, crime_type
It's not going to work any better with a function (like REGEXP_INSTR) that returns a NUMBER.
How can you fix it? That depends on what you want to do. Why are you calling REGEXP_INSTR? What is that condition checking?
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved, so that the people who want to help you can re-create the problem and test their ideas.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Always say which version of Oracle you're using (for example, 11.2.0.2.0).

I am looking for to decode the actual db value something in different for my report.
like if A then Accepted
elseif R then Rejected
elseif D then Denied
these conditions I have to check in where clause.

what are you trying to do?
may be you are looking for
select * from tab1,tab2
where a.tab1 = b.tab2
and

Using :case when in where clause

Hello,
I need some help with using of case statement in a where clause
Table that contains info about employees taking some coursework:
Class (values could be SAP, ORACLE, JAVA)
Code (if Class is SAP then CODE is not null; if class is any other CODE is NULL)
Start Date (date they began class not null)
End Date (date then ended the class - could be null)
Employee Level(numbers from one through five)
I need a single LOV in forms that should show Employee_Level for input class,code,date.
How to do this?
I started off with this but get 'missing statement error'
select distinct employee_level from e_course
   where (
   case when &class='SAP' then code ='1' and start_date > to_date('20000101','YYYYMMDD') and
                                           end_date < to_date('20000101','YYYYMMDD')
           else
               null
   end) order by employee_level;Thanks

Hi,
user469956 wrote:
But all these examples have only one condition for each case.Depending on how you count, all WHERE clauses have only one condition.
I see an example in that thread that has 6 atomic conditions, linked by AND and OR.
I need to check date & code. This is what is causing the error.Why do you want to use a CASE statement?
Why can't you put all your conditions directly iinto a WHERE clause, soemthing like this:
WHERE   (   &class='SAP'
        AND code ='1'
OR      (   start_date > to_date('20000101','YYYYMMDD')
        AND end_date    < to_date('20000101','YYYYMMDD')
        )I said "something like this" because I don't know what you really want to do.
