What is wrong with this simple query

Hi,
I am writting a simple code just to get the maximum no values from a database table
The query is
ResultSet = stm.executeQuery("SELECT MAX(column_name) FROM Database_table ");
it seems to be a simple one but i am getting the message
column not found
Please answer soon

Well, it depends on how your resultset is retrieving the results. If you retrieve by column name, then that's your problem. You need to do something like this:
ResultSet = stm.executeQuery("SELECT MAX(column_name) AS myColumnName FROM Database_table ");
String myResult = ResultSet.getString(myColumnName);Using MAX, COUNT, etc, will return your result with a mangled or no actual column name to retrieve from. Optionally, you can solve your problem by:
ResultSet.getString(1);Michael Bishop

What's wrong with this simple code?

What's wrong with this simple code? Complier points out that
1. a '{' is expected at line6;
2. Statement expected at the line which PI is declared;
3. Type expected at "System.out.println("Demostrating PI");"
However, I can't figure out them. Please help. Thanks.
Here is the code:
import java.util.*;
public class DebugTwo3
// This class demonstrates some math methods
public static void main(String args[])
          public static final double PI = 3.14159;
          double radius = 2.00;
          double area;
          double roundArea;
          System.out.println("Demonstrating PI");
          area = PI * radius * radius;
          System.out.println("area is " + area);
          roundArea = Math.round(area);
          System.out.println("Rounded area is " + roundArea);

Change your code to this:
import java.util.*;
public class DebugTwo3
     public static final double PI = 3.14159;
     public static void main(String args[])
          double radius = 2.00;
          double area;
          double roundArea;
          System.out.println("Demonstrating PI");
          area = PI * radius * radius;
          System.out.println("area is " + area);
          roundArea = Math.round(area);
          System.out.println("Rounded area is " + roundArea);

Can someone tell me what's wrong with this LOV query please?

This query works fine..
select FILTER_NAME display_value, FILTER_ID return_value
from OTMGUI_FILTER where username = 'ADAM'
But this one..
select FILTER_NAME display_value, FILTER_ID return_value
from OTMGUI_FILTER where username = apex_application.g_user
Gives the following error.
1 error has occurred
* LOV query is invalid, a display and a return value are needed, the column names need to be different. If your query contains an in-line query, the first FROM clause in the SQL statement must not belong to the in-line query.
Thanks very much,
-Adam vonNieda

Ya know, I still don't know what's wrong with this.
declare
l_val varchar2(100) := nvl(apex_application.g_user,'ADAM');
begin
return 'select filter_name display_value, filter_id return_value
from otmgui_filter where username = '''|| l_val || '''';
end;
Gets the same error as above. All I'm trying to do is create a dropdown LOV which selects based on the apex_application.g_user.
What am I missing here?
Thanks,

What's wrong with this ejb-query?

Hi people,
may be i worked too much, may be i've just missed something, but guys, can enyone tell me what the hell is wrong with this GOD DAMNED query?
<ejb-ql>Select Object(adt) From AddrDataTable AS adt, IN (adt.addresseeQualities) AS aq WHERE adt.season.id = ?1 And aq.aQTemplate.id=?2</ejb-ql>
That JBoss throws following exception:
org.jboss.deployment.DeploymentException: Error compiling EJB-QL statement 'Select Object(adt) From AddrDataTable AS adt, IN (adt.addresseeQualities) AS aq WHERE adt.season.id = ?1 And aq.aQTemplate.id=?2'; - nested throwable: (org.jboss.ejb.plugins.cmp.ejbql.ParseException: Encountered "1" at line 1, column 103.

The worst thing is that when i remove WHERE clause JBoss keeps silence like a fish - it works fine!
So, any ideas about this?
Thank you

Are you sure the ?1 and ?2 parameters exist in the method for which the query is addressed.
In the statement adt.season.id I guess season is a CMR field and then season has a CMP field called id
and the same for aq.aQTemplate.id, aQTemplate being the CMR field and the is being a CMP field in the CMR.
and in adt.addresseeQualities is a CMR field?
Looks like a complex query
SELECT OBJECT(adt) from BEAN AS adt,
IN(adt.CMR_FIELD) AS aq
WHERE
adt.ANOTHER_CMR.ANOTHER_AMR_CMP_FIELD=?1
AND
aq.2_CMR_FIELD.2_CMP_FIELD =?2

What's wrong with this simple method

i'm having compile troubles with this simple method, and i think it's got to be something in my syntax.
public String setTime()
String timeString = new String("The time is " + getHours() + ":" + getMinutes() + ":" + getSeconds() + " " + getIsAM());
return timeString;
this simple method calls the get methods for hours, minutes, seconds, and isAM. the compiler tells me i need another ) right before getSeconds(), but i don't believe it. i know this is a simple one, but i could use the advice.
thanks.

Hi,
I was able to compile this method , it gave no error

What's wrong with this sql query? Help

hi
i am having difficulty executing this query
ResultSet s=st.executeQuery("select * from employee where iden = ?"+id);
here in my program st is statement obg
iden is attribute name in table
id i am getting at run time from user
please help...it says wrong number of parameters
thank you

That's correct, get rid of the Question mark. Questions marks are used in PreparedStatements, but they are also used in pattern matching. I am assuming the iden is the table identity. Therefore, I am assuming it is numeric. If so, you can't use the question mark because pattern matching is only done with strings. If you are treating your statement as a PreparedStatement, then you have done it wrong. (See the API) Here is a code snippet from the API:PreparedStatement pstmt =
con.prepareStatement("UPDATE EMPLOYEES SET SALARY = ? WHERE ID = ?");
pstmt.setBigDecimal(1, 153833.00)
pstmt.setInt(2, 110592)It seems you are using a Statement object, so, you need to get rid of that question mark.

What is wrong with this simple CFIF statement?

Hi, I've included a simple cfif statment to check to see if a
user is already in the database, for some reaons the <cfelse>
part of the statement does not work. that is, if the user is there
it returns the recordcount and ID etc. but if it is a new user (no
records found) it is just blank (without the nothing doing !!!) any
ideas?
Thanks
Yankee

Based strictly on the code you have shown, you do not need
the query="getuser" in your cfoutput tag.
Also, I would check to see if the value is greater than zero
rather than equal to one. What if the person has more than one
record in the database?
Try this...
<CFIF getuser.recordcount GT 0>
#GetUser.RecordCount# Records Found
<CFELSE>
Doing Nothing
</CFIF>

What's wrong with this simple java file

I am learning java input methods. When I tried to compile the below simple java file, there were two errors.
import java.io.*;
public class MainClass {
   public static void main(String[] args) {
    Console console = System.console();
    String user = console.readLine("user: ");
    System.out.println(user);
}The compiler errors:

Could anyone take a look and shed some lights on this?

I have changed to "import java.io.Console;" but this below errors:

What is wrong with this simple for loop?

long number = 12345678;
        for(int i=1;i<=numberOfDigits;i++)
            int i = number/(i);
        System.out.println(i);
        Basically, I want to take to assign int 1 = , int 2 = , int 3 = up until the number of digits.
I still have to manipulate it, so the code makes no sesne, but how would I do that?
So, i want to assign ints up until 8 but the manipulation I have also involves i up until the number of digits.
Yhank you.

Fredddir_Java wrote:
I see that, but I just wanted to declare 8 ints (in this example, number of digits is 8) using a for loop, so I wanted to use the loop to assign these values one at a time. You know...but don't declare a variable with the same name as the loop variable. That just won't compile. Use an array as mentioned above.
How would you do that?If you are trying to find the digit at a certain point in your number, probably the easiest way is to translate the number to a Stirng and use String methods (if allowed) such as charAt(...). If not, then look at the mod operator "%" and at integer division.
Can anyone provide a basic loop for this task?Best not to ask for a code solution to homework here. We'll tolerate specific questions but not requests for code.

What is wrong with this simple getText

Alright, all im trying to do now is to have the user enter in a c d or f for their seat. If they do and everything else is correct, it should place an X in the array. However, even if i do a c d or f, it still goes to the else clause and never performs the intended if structure. I tried with integers and it worked fine, but our prof
insists we use letters. Please help

1) When posting code use the [url http://forum.java.sun.com/features.jsp#Formatting]Formatting Tags so the code is readable.
2) if(Seat == "a" || Seat == "c" || Seat == "d" || Seat == "f")
You don't use "==" when comparing equality of two Objects you use the equals(...) method.
if (seat.equals("a") ....
The "==" operator is only used when comparing primitive data types (int, char, long...)
3) Variable names should not start with an upper case character. Normally class names would start with an upper case character (look at all the classes in the API).

I can't figure out what's wrong with this code

First i want this program to allow me to enter a number with the EasyReader class and depending on the number entered it will show that specific line of this peom:
One two buckle your shoe
Three four shut the door
Five six pick up sticks
Seven eight lay them straight
Nine ten this is the end.
The error message i got was an illegal start of expression. I can't figure out why it is giving me this error because i have if (n = 1) || (n = 2) statements. My code is:
public class PoemSeventeen
public static void main(String[] args)
EasyReader console = new EasyReader();
System.out.println("Enter a number for the poem (0 to quit): ");
int n = console.readInt();
if (n = 1) || (n = 2)
System.out.println("One, two, buckle your shoe");
else if (n = 3) || (n = 4)
System.out.println("Three, four, shut the door");
else if (n = 5) || (n = 6)
System.out.println("Five, six, pick up sticks");
else if (n = 7) || (n = 8)
System.out.println("Seven, eight, lay them straight");
else if (n = 9) || (n = 10)
System.out.println("Nine, ten, this is the end");
else if (n = 0)
System.out.println("You may exit now");
else
System.out.println("Put in a number between 0 and 10");
I messed around with a few other thing because i had some weird errors before but now i have narrowed it down to just this 1 error.

what's wrong with this SQL?

Hi, everyone:
when I insert into table, i use the fellowing SQL:
INSERT INTO xhealthcall_script_data
(XHC_CALL_ENDED, XHC_SWITCH_PORT, XHC_SCRIPT_ID, XHC_FAX_SPECIFIED)
VALUES (SELECT TO_DATE(HH_END_DATE||' '||HH_END_TIME,'MM/DD/YY HH24:MI:SS'), HH_SWITCHPORT, HH_SCRIPT,'N'
FROM tmp_healthhit_load WHERE HH_SCRIPT !='BROCHURE' UNION
SELECT TO_DATE(HH_END_DATE||' '||HH_END_TIME,'MM/DD/YY HH24:MI:SS'), HH_SWITCHPORT, HH_SCRIPT,'N' FROM tmp_healthhit_load WHERE HH_SCRIPT !='BROCHURE');
I always got an error like;
VALUES (SELECT TO_DATE(HH_END_DATE||' '||HH_END_TIME,'MM/DD/YY HH24:MI:SS'), HH_SWITCHPORT,
ERROR at line 3:
ORA-00936: missing expression
but I can't find anything wrong, who can tell me why?
thank you so much in advance

For starters, an insert select does not have a values clause.

Even I see "missing VALUES" as the only error

...and why are you doing a UNION on the exact same two queries?
(SELECT TO_DATE(HH_END_DATE||' '||HH_END_TIME,'MM/DD/YY HH24:MI:SS') ,HH_SWITCHPORT ,HH_SCRIPT ,'N' FROM tmp_healthhit_load WHERE HH_SCRIPT !='BROCHURE' UNION SELECT TO_DATE(HH_END_DATE||' '||HH_END_TIME,'MM/DD/YY HH24:MI:SS') ,HH_SWITCHPORT ,HH_SCRIPT ,'N' FROM tmp_healthhit_load WHERE HH_SCRIPT !='BROCHURE');

Hi,
thank you for your answer, but the problem is, if I deleted "values" as you pointed out, and then execute it again, I got error like "ERROR at line 3:
ORA-03113: end-of-file on communication channel", and I was then disconnected with server, I have to relogin SQLplus, and do everything from beganing.
so what 's wrong caused disconnection, I can't find any triggers related. it is so wired?
I wonder if anyone can help me about this.
thank you very much
jerry

Hi,
acturlly what I do is debugging a previous developer's scipt for data loading, this script was called by Cron work, but it never can be successfully executed.
I think he use union for eliminating duplications of rows, I just guess.
thank you

Scratch the VALUES keyword then make sure that the select list matches the column list in number and type.
1 insert into marktest
2 (fld1, fld2, fld3, fld4, fld5)
3* select * from marktest
UT1 > /
16 rows created.

try this - just paste the code and give me the error- i mean past the entire error as it is if error occurs
INSERT INTO xhealthcall_script_data
(xhc_call_ended, xhc_switch_port, xhc_script_id,
xhc_fax_specified)
SELECT TO_DATE (hh_end_date || ' ' || hh_end_time, 'MM/DD/YY HH24:MI:SS'),
hh_switchport, hh_script, 'N'
FROM tmp_healthhit_load
WHERE hh_script != 'BROCHURE'
UNION
SELECT TO_DATE (hh_end_date || ' ' || hh_end_time, 'MM/DD/YY HH24:MI:SS'),
hh_switchport, hh_script, 'N'
FROM tmp_healthhit_load
WHERE hh_script != 'BROCHURE';

Hi, Jagan:
thank you very much for your answer.
but when I execute it, I still can get error like:
ERROR at line 1:
ORA-03113: end-of-file on communication channel
so wired, do you have any ideas?
thank you very much

And this one,
Aother question about SQL?
I thought I already told him to deal with
ORA-03113: end-of-file on communication channel
problem first.
There's nothing wrong (syntax wise) with the query. (of course when no "value" in the insert)

What is wrong with this simple query
