Trouble with a simple Query

Hello, I'll start by saying that I am a noob. Anyways, I am trying to do what I thought would be a simple query to get records that are greater than or equal to the current date: this is my query...
<cfquery name="getUpcoming" datasource="events">
SELECT title, eventDate FROM event WHERE eventDate >= #Now()# ORDER BY eventDate ASC
</cfquery>
It works, sort of, I do get records that are greater than the current date, but any records that are equal to do not show up.
I am assuming that it is looking at time as well, or I am doing it completely wrong. I don't know? Any help would be greatly appreciated.

I didn't use the cfqueryparam as suggested, is there something dangerous about doing it this way?
Nothing dangerous, no. Just "less than ideal" (in a sloppy / lazy sort of way). As I suggested, one should not hard-code dynamic values into the SQL string, one should pass them as parameters. it's just "the way it should be done".
When the DB receives your SQL string (with the dynamic values hard-coded), the DB engine needs to compile the SQL to make an execution plan before executing the query. Any change to the SQL string requires recompilation. However if you pass your parameter as parameters, then the SQL does not need to be recompiled.
It's the same sort of thing as not using global variables unless one has to, despite the fact they're "easier", or duplicating code instead of refactoring code. One should try to write decent code.

Help with a simple query

Hi ,
I'm running the following simple query in sql*plus on ORACLE9i. But this query stopped running after 30minutes, and the sql*plus die at the same time .I have no idea about this. Could somebody tell me how I can solve this problem. Thank you very much for your help.

Trouble with a simple transition

I'm new to actionscript and trying to wrap my head around some simple scripting, but am having trouble.
My goal in this excercise is to have one symbol/movie clip in frame 1 (stopped on that frame) and then, when clicked, the first cube will dissapear and transition to a different symbol/movie clip in frame 2.
Here is my script:
stop();
stationary1.addEventListener(MouseEvent.CLICK, transition);
function transition(evt:MouseEvent):void {
evt.currentTarget.gotoAndStop(2);
evt.currentTarget.mouseEnabled = false;
The movie clips I'm working with are just revolving cubes that are different colors. What happens when I run this script is the initial cube is there spinning as intended in frame 1, then when I click it the initial cube freezes and the other cube doesn't show up.

you probably don't want the evt.currentTarget to advance to frame 2. that would be the 2nd frame on stationary1's timeline.
try:
stop();
stationary1.addEventListener(MouseEvent.CLICK, transition);
function transition(evt:MouseEvent):void {
gotoAndStop(2);

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

I'm having Trouble with a Simple Histogram

The program as a whole is supposed to read a text file, count the number of words, and ouput it. For example, "The The The pineapple pineapple" should ouput "The 3, Pineapple 2" I've gotten as far as dumping the tokens into an array and creating 2 empty arrays of the same size(word, count), but I don't know how to do the double loop that's necessory for the count.

Couple of points to begin with:
1. Class names should begin with an upper case letter
2. Class names should be descriptive
3. You shouldn't call your class main (this kind of follows from the first two points).
4. Always use {} around blocks of code, it will make your life, and those of the people who have to eventually maintain your code a lot easier.
5. Never ignore exceptions, i.e. don't use an empty block to catch exceptions.
6. Avoid assiging a local variable to null, especially if the only reason you are doing it is to "fix" a compilation error.
7. Your method names should reflect everything that the method does, this should encourage you to break the application logic down into the smallest tasks possible (a general rule is that each method should do one task, and do it well). In the example below, I ignore this advice in the loadFile() method, but it's left as an exercise to you to fix this.
8. You should use descriptive variable names (fin may make sense now, but will it in 6 months time?), and use camel case where the name uses multiple words, e.g. wordcount should be wordCount
On the problem at hand, I'll post a cut down example of what you want, and you can look at the javadocs, and find out how it works.
This code uses the auto-boxing feature of 1.5 (even though I don't like it, again it's left as an exercise for you to remove the auto-boxing ;) ) and some generics (you should be able to work out how to use this code in 1.4).

A few notes:
1. You seem to have either a VPD policy active or you're using views that add some more predicates to the query, according to the plan posted (the access on the PK_OPERATOR_GROUP index). Could this make any difference?
2. The estimates of the optimizer are really very accurate - actually astonishing - compared to the tkprof output, so the optimizer seems to have a very good picture of the cardinalities and therefore the plan should be reasonable.
3. Did you gather index statistics as well (using COMPUTE STATISTICS when creating the index or "cascade=>true" option) when gathering the statistics? I assume you're on 9i, not 10g according to the plan and tkprof output.
4. Looking at the amount of data that needs to be processed it is unlikely that this query takes only 3 seconds, the 20 seconds seems to be OK.
If you are sure that for a similar amount of underlying data the query took only 3 seconds in the past it would be very useful if you - by any chance - have an execution plan at hand of that "3 seconds" execution.
One thing that I could imagine is that due to the monthly data growth that you've mentioned one or more of the tables have exceeded the "2% of the buffer cache" threshold and therefore are no longer treated as "small tables" in the buffer cache. This could explain that you now have more physical reads than in the past and therefore the query takes longer to execute than before.
I think that this query could only be executed in 3 seconds if it is somewhere using a predicate that is more selective and could benefit from an indexed access path.

Trouble with a SQ01 Query...

Hi all!! what's up!
I need to show a new field in a Query, I already include it in my infoset, and in the query visualization, but when I try to execute the Query, it shows all the old fields and don't show my new field... How can I do it??
Thanks a lot and sorry for my English.

Ok, let's see...
At first, I modified the Infoset (SQ02) , including my new field in a Fields Group.
And Next, I switched on all the boxes in SQ01 of my New Field...
My field is EINE-NETPR... the EINE Table was on the query before, with other fields too.

Ora-6000 with a simple query

Hi,
I registered three XSD schemas, they were created by "trang" as you can read at:
XML schema register , tables and types.
After I corrected namespace and i added following options: storeVarrayAsTable="true", maintainDOM="false" and a defaultTable.
They were register successfull, and all tables was created either. I insert three little XMl files in the default table. Three rows were created (I try: select count(*))
Then I try this query:
Query:
select extract(object_value,'/') from mitablename;
but I got this error:
Error:
ORA-00600: código de error interno, argumentos: [kokax_oct_adtcbk5], [], [], [], [], [], [], []
If I try the same query in SQLdeveloper i get this:
http://img484.imageshack.us/img484/7017/ora00600lu7.jpg
I'm trying with oracle XE here at home.
Did anyone know anything about this error ?
thanks!

It is a long shot, but because of "XE", the ORA-0600, and maybe because you don't have a customer support id.; you could re-install XDB. This will invalidate all your schema based structures and repos. stuff (if dependend on the XDB schema). The XDB schema will be dropped be dropped during this excercise...so make a backup if needed !!!
For *nix OS systems the following could be done to re-install XDB - MAKE A FULL (RMAN) BACKUP of your DATABASE
conn / as sysdba
spool /tmp/reinstall.log
@?/rdbms/admin/catnoqm.sql
shutdown immediate
startup
@?/rdbms/admin/catqm.sql
spool off
No "mayor" errors should be notified in the spooled log file. If so re-try once to run catqm.sql

Hello oracle gurus ... I have a trouble with the following query ...

Any help would be appreciated ...
My oracle database ...
producttype --|-- creationtime --|-- count
2 --|-- 4/07 --|-- 5
2 --|-- 5/07 --|-- 6
1 --|-- 5/07 --|-- 9
I need to write a query to populate a dataset. The table I should construct later will have to look like this, sort off ...
creationtime --|-- 1 (producttype) --|-- 2 (producttype)
4/07 --|-- 0 --|-- 5
5/07 --|-- 9 --|-- 6
The example is self explanatory and I wanted to make it as minimalistic as posible.
One other problem. When you look at that creationtime column up there. I will have to generate that separatelly as it seems to me. The user has an option to select a startdate and an enddate. My creationtime column will have to contain every month between those two dates the user had selected. That doesn't mean I will find EVERY month in the actual oracle database. However, I have to check for it and if a given month is not found I have to assign value "0" for both 1 and 2 (producttypes) and the month should still be present in the creationtime column in my dataset.
Any tips would be welcomed.
Thanks.

The example is self explanatory and I wanted to make it as minimalistic as posible.It is not self explanatory. Raw data can be interpreted in a number of ways: we need to understand what these things mean. Minimalism is fine (I'm a big Phillip Glass fan myself) but too little is not good enough. For instance, is COUNT a column name or the output of a COUNT function? Are there really only two ProductTypes?
Depending on the answers to those questions something like this query may or may not work for you...
select creationtime
, sum(decode(producttype,1, count, 0)) as pt1
, sum(decode(producttype,2, count, 0)) as pt2
from your_original_table
group by creationtime

Problem with a simple query

Hey. I've got a table which contains only one entry:
Table "users":
id | date | user | pass | profile | last_logged
1 | ... | evo | ... | ... | ...
My query is: "SELECT * FROM users WHERE user=evo". The problem is that im always gettings a null pointer exception, but if I get the data by refering to the id (WHERE id=1) then it works! Why is this?
I've got a login system which takes the username from the form and attempts to get the id corresponding to the user value. But it just won't work. help appreciated. Thanks.

Is the user column of type string and evo a string value?
Which database are you using?
Don't you have to put single quotes around that?
String query = "SELECT * FROM users WHERE user = 'evo'"MOD

Adding a column makes big difference with a simple query

Hello All,
The oracle environment I am working with is
Oracle9i Enterprise Edition Release 9.2.0.8.0 - 64bit Production
and
PL/SQL Release 9.2.0.8.0 - Production
I have a question for the following 2 queries. The only difference is that first one has an extra field than the second one. That extra field makes big difference regarding excution time. One is 4 seconds and the other is 5 minutes. Could anyone help me to understand why? Thank you for your help! -Susan

what is the web server u r using ?
what jars have u in the lib directory?
I believe this is a version /configuration problem

I have trouble with the simple task of make a paper copy of an e-mail. There is not tab for that.

I receive an e-mail that I want to copy, such as an airline or car reservation. There is no tab that I have found where I can copy that reservation. Don't know why there is not a prominent tab which I can press to copy the e-mail. Maybe it is there but I have not found it. Very confusing.

I've tried to copy-paste the message, but I get only the body, not the To/From. I'd like to be able to save a thread as a .doc, but I haven't figured out a way to do that. PrntScrn copies the image of the entire screen on the monitor, including the entire Thunderbird screen, and it's an image, not editable.
I've tried to show all headers, and I still get only the body. Only if I actually PRINT the email do I get the To/From/Subject/Date.
Any way to copy ALL the common information about an email, to paste into another .doc?

I have download the NAVTEQ sample data pack and in the process of importing it, but it seems that using 700mb of data for me to ask oracle "given this point, tell me what country or ocean it is in" would be overkill.
An option would be to load the entire data set, then delete the stuff you don't need (lower level admin boundaries, etc). Of course, at the end of the day it depends on how accurate you want your results to be. The more accurate the data, the more confidence you will have in the result.
