CFC Best Practise : Using cfif statements in Where Clause

Hi there
Wondering if anyone can advise on the best route to take for handlings cfcs...
I have a function set up as so

    <cffunction name="getSong" access="remote" output="false" returntype="query" hint="return song information, filtered by user id">
    
    <cfargument name="nameArt" type="string" required="false" hint="artist we want to grab song for">
    
    <cfargument name="idUsr" type="any" required="false" hint="if provided, filter by user id">
    
    <cfargument name="nameUsr" required="false" type="string" hint="if supplied, filter by user name">
     
    <cfargument name="idSng" required="false" type="numeric" hint="if supplied, grab information for song with this id">
    
     <cfquery name="song" datasource="#APPLICATION.mx#">
         // SELECT WHICHEVER FIELDS NECESARRY
         SELECT.....
         
         <cfif isDefined('ARGUMENTS.idUsr')>
        
         WHERE s.userId = <cfqueryparam value = '#ARGUMENTS.IdUsr#' cfsqltype='CF_SQL_INTEGER'>
         </cfif>
         
          <cfif isDefined('ARGUMENTS.nameUsr')>
        
         WHERE s.userId =     (SELECT iUserID
                            FROM users
                            WHERE name = <cfqueryparam value = '#ARGUMENTS.nameUsr#' cfsqltype='CF_SQL_VARCHAR' maxLength="12">)
         </cfif>
        <cfif isDefined('ARGUMENTS.idSng')>
         WHERE s.iSongID = <cfqueryparam value = '#ARGUMENTS.idSng#' cfsqltype='CF_SQL_INTEGER'>
         </cfif>
         ORDER BY s.iSongID DESC
    </cfquery>
    
        <cfreturn song>
    </cffunction>
Now im wondering, is it best to have multiple cfifs in the same function, filtering data dependant on what arguments are supplied, or is it best to seperate the function into seperate functions with different filters, without the cfifs?
Many thanks

Also keep in mind that some of your logic can be done on the database side instead of the CF side:
SELECT myFieldA, myFieldB
FROM myTable
WHERE myFieldA = CASE WHEN isNULL(@MyDBVar,'') = '' THEN myFieldA ELSE @MyDBVar END
Will filter your results matching the field myFieldA against the value of the variable @MyDBVar (if it is passed in). You can also use conditional logic to make larger changes to your database query depending on the DB you are using.

Using Case Statement in Where Clause

Hello All,
I wish to conditionally use different columns for retrieving unique row. This will be dependent upon a parameter passed to the Function/Procedure.
The SQL framed looks as below:
+select *+
from Test_Table
where column_1 = <some_value>
and case when p_call_location = 'A' then column_2 like '%ABC%'
when p_call_location = 'B' then column_2 Not Like '%ABC%'
when p_call_location = 'C' then column_3 like '%EFG%'
when p_call_location = 'D' then column_3 like '%IJKL%'
END;
However, I am not sure if this works, as I am getting a Missing Right Paranthesis error. Major hinderance is the depedency on multiple columns, which would need to be referred for particular scenario.
Can somebody please help me with an example or a skeleton of how a query should be formed?
Appreciate an early reply!!!

HI,
i think this may solve your issue...get back to me if u have any qry's on this.
CREATE TABLE Test_Table
(p_call_location VARCHAR2(10),
COLUMN_1 VARCHAR2(20),
COLUMN_2 VARCHAR2(20),
COLUMN_3 VARCHAR2(20))
INSERT INTO Test_Table VALUES('A','COMNVAL','ABC_PER','XXXX');
INSERT INTO Test_Table VALUES('A','COMNVAL','PER','XXXX');
INSERT INTO Test_Table VALUES('B','COMNVAL','ABC_PER','XXXX');
INSERT INTO Test_Table VALUES('B','COMNVAL','PER','XXXX');
INSERT INTO Test_Table VALUES('C','COMNVAL','ABC_PER','EFG_XXXX');
INSERT INTO Test_Table VALUES('C','COMNVAL','ABC_PER','XXXX');
INSERT INTO Test_Table VALUES('D','COMNVAL','ABC_PER','EFG_XXXX_IJKL');
INSERT INTO Test_Table VALUES('D','COMNVAL','ABC_PER','GGG_XXXX');
SELECT * FROM Test_Table WHERE ROWID IN (
select case when p_call_location = 'A' AND column_2 like '%ABC%' THEN ROWID
when p_call_location = 'B' AND column_2 Not Like '%ABC%' THEN ROWID
when p_call_location = 'C' AND column_3 like '%EFG%' THEN ROWID
when p_call_location = 'D' AND column_3 like '%IJKL%' THEN ROWID
END AS KK
from Test_Table
where column_1 = 'COMNVAL');
even u can use the below qry also
select *
from test_table
where column_1 = 'COMNVAL'
and (case when p_call_location = 'A' and column_2 like '%ABC%' then 'VALID'
when p_call_location = 'B' and column_2 Not Like '%ABC%' then 'VALID'
when p_call_location = 'C' and column_3 like '%EFG%' then 'VALID'
when p_call_location = 'D' and column_3 like '%IJKL%' then 'VALID'
else 'INVALID'
END) = 'VALID';
thanks

Case statement in where clause ??

Hello gurus,
Can we use case statements in where clause ?? Any example will be great!
And also i would like to know, besides CASE and DECODE statements, Is there any way we can use IF ELSE statements in SELECT clause or in WHERE clause ?
Thank you!!

Hi,

Hoek,
Thanks for the reply
Whatever you return from 'then' should match your criteria.I didnt get this part...can you elaborate this part ?? Thank you!!Remember what a CASE expression does: it returns a single value in one of the SQL data types (or NULL).
You're probably familiar with conditions such as
WHERE   col = 1Inthe example above, col could be replaced by any kind of expression: a function call, and operation (such as "d * 24") or a CASE expression, which is exactly what Hoek posted:
where case
         when col = 6 then 1
         when col = 9 then 1
       end = 1;I think what Hoek meant about mnatching was this: since the CASE expression is being compared to a NUMBER, then every THEN clause (as well as the ELSE, if there is one) should return the same data type. You can't have one THEN clause return a NUMBER, and another one in the same CASE expression return a DATE, like this:
where case
         when col = 6 then 1
         when col = 9 then SYSDATE     -- WRONG! Raises ORA-00932: inconsistent datatypes
       end = 1;
By the way, it's rare when a CASE expression really helps in a WHERE clause. CASE is great for doing conitional stuff in places where you otherwise can't (in the ORDER BY clause, for example), but the WHERE clause was designed for conditions.
Hoek was just trying to give a simple example. If you really wanted those results, it would be simpler to say:
where col = 6
or     col = 9and simpler still to say
where col IN (6, 9)

How to use CASE stmt in Where clause

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

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.

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.

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 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.

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>

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.

Case statement within where clause

How can i write a case statement within Where clause of SQL statement.
Ex:
If sysdate is less than Dec 31 of 2009 then run the query for 2009 else run the query for 2010.
belwo query is not working. Please let me know how can i write a case statement within where clause.
Select * from table
where
Case
when to_char(sysdate,'yyyymmdd')<=20091231 then tax_year=2009
else tax_year=2010
End

Hi,
You can get the results you want like this:
Select *
from      table
where   tax_year = Case
                  when to_char(sysdate,'yyyymmdd') <= 20091231
                  then 2009
                  else 2010
             End
;A CASE expression returns a single value in one of the SQL data types, such as a NUMBER, VARCHAR2 or DATE. There is no boolean type in SQL.

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.
SQL> CREATE TABLE my_table (id NUMBER, description LONG);
Table created.
SQL> INSERT INTO my_table VALUES (1, 'FIRST LONG');
1 row created.
SQL> INSERT INTO my_table VALUES (2, 'ANOTHER LONG');
1 row created.
SQL> COMMIT;
Commit complete.
SQL> CREATE TYPE my_type_row AS OBJECT (id INTEGER, description CLOB);
2 /
Type created.
SQL> CREATE TYPE my_type_table AS TABLE OF my_type_row;
2 /
Type created.
SQL> CREATE OR REPLACE FUNCTION get_my_long
2     RETURN my_type_table
3     PIPELINED
4 AS
5     v_tab   my_type_table := my_type_table ();
6 BEGIN
7    FOR cur IN (SELECT id, description FROM my_table)
8 LOOP
9        PIPE ROW (my_type_row (cur.id, cur.description));
10 END LOOP;
11 RETURN;
12 END;
13 /
Function created.
SQL> SELECT
2     id,
3     description
4 FROM
5     TABLE (get_my_long ())
6 WHERE
7     description LIKE '%LONG'
8 ORDER BY
9     DBMS_LOB.SUBSTR(description);
ID DESCRIPTION
   2 ANOTHER LONG
   1 FIRST LONG
SQL> SELECT
2     id,
3     description
4 FROM
5     TABLE (get_my_long ())
6 WHERE
7     description LIKE 'FI%';
ID DESCRIPTION
   1 FIRST LONG

How to use a case statement in where clause

Hi All,
I have a requirement which is to bring all the claims that are created in the last month.So, i wrote a query something like this
select * from claims
where
(Month(ClaimOpenDate) = Month(Getdate())-1 and year(claimopendate) = year(getDate()))
which would give me any new claims created in last month of current year, but this condition fails if we are in the first month of a new year( lets say if we are in 2016 jan then month(getdate())-1 would be 0 and year(getdate()) would be 2016 so we dont
find any records where year is 2016 and month is 0 for claimopen).
So, i would like to use a case statament or something which can help me get around this one.
Can someone please help me with any suggestions?
Thanks

So if i use your logic in the end for both the where clauses its been more than 10 minutes and the query is still running however if i use my old method it doesnt even take a second. Looks like its affecting the execution plan. Any suggestions to get around
this one please?
Thanks

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).
