Using TRIM function in select statement

Hi All,
I'm using the TRIM function in my select statement to eliminate the white spaces.
But while using in select the TRIM function is not working in SQL*PLUS client(The query returns the white spaces also)
Kindly provide some pointers regarding the issue.........
I want to get only the data without the spaces in select statement
Regards,
Mohan

Hi, Mohan,
SQL*Plus always pads columns to make them line up nicely.
If you have a column declared as VARCHAR2 (20), then SQL*Plus will normally display 20 characters for that column, even in the maximum actual length is, say, 5 (or even if the column always happens to be NULL).
If you want the output to include only the actual data, without the padding that SQL*Plus adds, then concatenate all the columns into one big string column.
People often do something like the following to generate a CSV file, with no exta spaces:
SELECT       TO_CHAR (empno)
|| ',' || ename
|| ',' || job
|| ',' || TO_CHAR (deptno)
|| ',' || TO_CHAR (hiredate, 'DD-Mon-YYYY')     AS all_data
FROM          scott.emp;

Using java function in select statement

Hi,
I am trying to use java function in select statement.
public class ClassA{
     private static String MyConst = "foo";
     public static String functionA(){
          return MyConst;
in my query I have:
select
     ClassA.functionA() AS id,
     groupId AS newID,
from
     myChannel[now]
ClassA is part of the application (no need to import).
I get and error of Invalid Expression on ClassA.functionA().
I also tried to declare the function in the processor element:
<wlevs:processor id="proc">
     <wlevs:function function-name="A" exec-methode="functionA">
          <bean class="mtPackage.ClassA"/>
     </wlevs:function>
<wlevs:processor>
but then I get a different error in the processor XML file: "An InvocationTargetException was encoutered while attemting to register the user defind function A. The message was null"
What am I missing here?

Hi,
From the above description, you have tried two manners to call method functionA() in the user defined class ClassA. One uses java cartridge manner directly and the other try to use user defined function manner.
For the java cartridge manner, the following CQL query should work if the ClassA is really included in the OEP app. I have done similar test before, it works.
select
     ClassA.functionA() AS id,
     groupId AS newID,
from
     myChannel[now]
For user defined function manner, I think two things you need to change:
1. Need to declare the function in the EPN assembly file(under META-INF/spring/), not component configuration file(under META-INF/wlevs/). The following is an example:
<wlevs:processor id="proc">
     <wlevs:function function-name="A" exec-methode="functionA">
          <bean class="mtPackage.ClassA"/>
     </wlevs:function>
</wlevs:processor>
2. Call the user defined function in the CQL query in the component configuration file under processor. For example:
select A() from myChannel

Using function in select statement

Hi,
CREATE FUNCTION [dbo].[udf_testFunction]
@value int

AS
BEGIN
-- Declare the return variable here
declare @returnValue int
set @returnValue = @value*2;
return @returnValue;
END
GO

select EmpID,EmpName, [dbo].[udf_testFunction](EmpID), [dbo].[udf_testFunction](EmpID)*EmpID,[dbo].[udf_testFunction](EmpID)+2 from #Temp
In the above select statement i used [dbo].[udf_testFunction]() function 3 times. But i want to use only once and reuse it.
Something like
select EmpID,EmpName, testfunctionvalue,testfunctionvalue*EmpID,testfunctionvalue+2 from #Temp
Please advise me.... Thanks in Advance...

You can use this code:
WITH cte
AS ( SELECT EmpID ,
EmpName ,
[dbo].[udf_testFunction](EmpID) AS testfunctionvalue
FROM #Temp
SELECT EmpID ,
EmpName ,
testfunctionvalue ,
testfunctionvalue * EmpID ,
testfunctionvalue + 2
FROM cte
But using scalar functions in select clause can hurt the performance. Please see this link:

PL/SQL Function in Select statement

Hi
I am calling a function in select statement. The query works in Toad and PL/SQL developer except SQL plus and disconnecting Oracle connection.
The error is “ERROR at line 1: ORA-03113: end-of-file on communication channel”.
When I called the same query from BC4J View Object the error message is “java.sql.SQLException: No more data to read from socket”.
Can any one advise me please?
Thanks

I've seen similar cases in the past with 9.2.0.x (x <= 5). What Oracle version are you using? It's worth checking the bug database (I can't just now - I don't have a valid support id in my current contract). And as Warren says, post your SQL query.

How to use a function in select clause

hi gems...good evening...
I want to write a select clause from a function. The scenario is like below:
function parameters
CREATE OR REPLACE FUNCTION FUNCTION_DEMO(p_pid IN NUMBER,
p_bankerNum IN NUMBER,
p_banker_name IN VARCHAR2,
p_business_num IN NUMBER,
p_businesses IN table_typ_businesses)

My function is compiled successfully. I just want to make the select query to view the output given by the function i.e the table type "table_typ_bankers".
Please help...thanks in advance..

Hi ,
You can check this and change your code by taking this as an example. I just noted down with simple one input and return as collection type
and how to use/call it in select statement.

/* Now creating a demo function and just focusing on your one input as collection type */

Error when trying to use trim function

when i try to use trim function on a column it gives me following error for the below query
select trim(first_name) name from table1@pa1;
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
DSNT408I SQLCODE = -440, ERROR: NO FUNCTION BY THE NAME TRIM HAVING COMPATIBLE ARGUMENTS WAS FOUND IN THE CURRENT PATH DSNT418I SQLSTATE = 42884 SQLSTATE RETURN CODE DSNT415I SQLERRP = DSNXORFN SQL PROCEDURE DETECTING ERROR DSNT416I SQLERRD = -100 0 0 -1 0 0 SQL DIAGNOSTIC INFORMATION DSNT416I SQLERRD = X'FFFFFF
any idea gurus ???Thanks

This might work:
select trim(first_name) name from
(select first_name from table1@pa1);The problem is that pa1 is a non-Oracle database and does not have a trim function. It may have another function that does the same thing but it's not called TRIM.

Error by using database procedure in select statement

hi ,
I have built a database procedure having one parameter with in out varchar type. that return value with some addition.
i am using it with some column in select statement only for display purpuses but i am facing error by doing that in select statement. that procedure is working well with bind variable but not with select statement.
plz help me how i can use a procedure in select statement. or can i do it or not.

plz help me how i can use a procedure in select statement. or can i do it or not.A workaround could be to create a wrapper function for your procedure. One that only passes the input parameters and returns the output parameter.
The simply call this function in your select which internally calls the procedure.

About using TRIM function...

//I'm posting this after whole search of past discussion as everybody wants to do so. :-)
Hi,
I want to trim out white spaces from colums in my table when select executes.
I've read about TRIM function, but it does not as documented I think.
See below my pseudo-code from trimming.
SELECT trim (' ' from col1) | | col2, FROM TH_ABLICEN WHERE..blah..blah..This SQL query return me "ORA-00907: missing right parenthesis".
I don't know how can this returns...
TRIM function works only when its parameter is a constant and fails always when columns were injected as a parameter.
This situation is very obscure to me and make me wondering ORACLE's intention for this kind of inconvenience.
And I've tried replace (col1, ' ', '') only to fail.
So my question is...
1. How can use trim function?
2. What is the ordinary method being used by popular demand to trim out white spaces from a column?
Thanks in advance
Regards,
Ryan

Hello,
Your query is correct. I tried it with 8.1.6 sql version. I modified it as follows.
select trim(' ' FROM ENAME)| |JOB FROM EMP;
about syntax you can specify column name in trim.
hope reply from you.

As mentioned in my first posting, it returns "ORA-00907: missing right parenthesis" error.
Anyway thanks for your concern.

How to pass rowtype argument to a function from select statement?

Hi all!
I have function that takes mytable%rowtype as in parameter. can I pass entire row of mytable to the function from select statement? kind of
select myfunction(mytable.*) from mytable where ....
Thanks in advance

The function can be used in a SQL statement only if it accepts SQL types and returns SQL type. %ROWTYPE being PL/SQL construct and not a SQL datatype, can not be used in this context.

How to use SET ID in select statement of SQ02

Hi,
I have a infoset, where for one of my Zfield, i have writen a select statement in order to get my ouput.
if aufk-aufnr = 'XYZ'.
select sum( FKBTR ) from fmifiit into zfmifiit
where fikrs = aufk-kokrs
and fipex IN capex
and wrttp NE '51'.
endif.
For the above statement, i have created (with 10 single values, table name FMCI, field name FIPEX) a SET id named CAPEX and used with IN operator.
But when i generating the infoset i am getting error like below
The IN operator with "CAPEX" is followed neither by an internal table nor by a value list
I was using IN opeartor for set ids during validation / substitutions, where if i have to validate multiple single values.
What to do here?

Using plsql tables in select statement of report query

Hi
Anyone have experience to use plsql table to select statement to create a report. In otherwords, How to run report using flat file (xx.txt) information like 10 records in flat files and use this 10 records to the report and run pdf files.
thanks in advance
suresh

hi,
u can use the utl_file package to do that using a ref cursor query in the data model and u can have this code to read data from a flat file
declare
ur_file utl_file.file_type;
my_result varchar2(250);
begin
ur_file := UTL_FILE.FOPEN ('&directory', '&filename', 'r') ;
utl_file.get_line(ur_file, my_result);
dbms_output.put_line(my_result);
utl_file.fclose(ur_file);
end;
make sure u have an entry in ur init.ora saying that your
utl_file_dir = '\your directory where ur files reside'

Unable to call local function in select statement.

Hi all,
I am unable to call the local function in select statement in below scenario.
DECLARE
l_cnt NUMBER;
FUNCTION FUN1 RETURN NUMBER
AS
BEGIN RETURN 2;
END;
BEGIN
SELECT FUN1 INTO l_cnt FROM DUAL;
DBMS_OUTPUT.PUT_LINE(l_cnt );
END;
/Any alternate way to call local function in select statement?
Thanks
Ram.

Hi,
Sorry, you can't call a locally defined function in a SQL statement, even if that SQL statement is in a PL/SQL block where the function is in scope.
This applies to packages, also. If a function is not declared in the package spec, but only in the package body, then you can't call it from SQL statements in the package body.
Why do you want a locally defined function? Why not a function defined outside the procedure?

Using functions in select statement(joining 5 tables) taking long time in Oracle

I have created a query in oracle which joins 5 tables and uses two functions(function names are 'ca_concat' and 'ca_concat_noseq').

Using Column Name returned by function in SELECT statement

Hi
Output from my function (RETURN data type is VARCHAR2) is column name. I want to use it directly in my SELECT statement. Below is simplified example of this:
--- Function
CREATE OR REPLACE FUNCTION simple RETURN varchar2 IS
BEGIN
RETURN ‘my_column’;
END simple;
--- Select
SELECT simple FROM my_table;
This does not work. It seems that output from function is passed in quotation i.e.
SELECT ‘my_column’ FROM my_table;
So the output from SELECT is a list of rows populated with values my_table:
COLUMN     simple
ROW1     my_column
ROW2     my_column
ROW3     my_column
Can please someone help me with this?

I'm not sure I got you right.
In standard SQL everything must be known at compile time. If not dynamic SQL is required, but is a costly operation (usually requires parsing before each execution) so it should better not be used when standard SQL can do it.
I provided a design time example where a function returns the column name from the given the table name and column id for a varchar2 column data type to make things simple. Then a query string is constructed and executed dynymically to return all column values of the chosen table_name.column_name.
SELECT simple FROM my_tableAt compile time the simple function return value is unknown (any varchar2 value would do) you already find out you get the (same) return value (i.e column name) for each table row => dynamic SQL needed to get the column values
The purpose of function would be to rename all columns for provided table.The table name would be provided, right? If yes => dynamic SQL
What is the function supposed to return the column name (where would the new name come from?), the column alias (which table column would be renamed to the new name?)
The user could use the new_column name as the column alias name submitting the query.
Is it possible to do this?Maybe () using a pipelined function (different data types - number,date, ... not cosidered yet) but your simple query;
<tt>SELECT simple FROM my_table</tt>
might look like:
<tt>select my_column_value new_column_name from table(get_column_value(table_name,column_name))</tt>
Sorry, no Database at hand to provide a specific example.
