Problem with a simple query
Hello, I'll start by saying that I am a noob. in any case, I'm trying to do what I thought was a simple query for records that are greater or equal to the date of the day: it's my request...
< cfquery name = "getUpcoming" datasource = 'events' >
SELECT title, eventDate FROM event WHERE eventDate > = #Now () # ORDER BY ASC eventDate
< / cfquery >
It works, so, I get the records that are greater than the current date, but all records that match to are not.
I guess that it is looking at the time as well, or should I completely wrong. I do not know? Any help would be greatly appreciated.

Problem with the simple query.
Hi all
I am facing problem with the query below
Select A.COL1, A.COL2
B.COL1, B.COL2
FROM TABLE1 A
TABLE 1 B
WHERE A.header = '123'
AND B.header = '123'
AND nvl (A.COL6, 'ABC') = 'ABC '.
AND NVL (B.COL6, 'DEF') = 'DEF '.
Basically, my requiremenyt is: I have only one table, TABLE1 here, which has a line two lines (for the same header) as "ABC" and another is "DEF". Table 1 has two columns (col1, col2) that should be displayed for both lines.
When the header has two records in table1 top query works. and but if I do not have a record for any header example there are a record for "abc" in col6 only. so my query above does not work because there is no record for 'DEF' in col6. But I want to again request to fecth the output (for b.col1 and b.col2 should have null values)
could you pls suggest me how to get the 4 columns.
Thanks in advance
Kind regards

Try to place the status of outer join on column: analytical_criterion_code as
and nvl (AUDIT.analytical_criterion_code, 'AUDIT2') = 'verification2. '
.
.
and nvl (TRANS.analytical_criterion_code, 'TRANS2') = 'TRANS2.
In the sub query based on the opinions that you have given in post # 1, although there is no value "DEF * ' for col6 due to the condition of outer join on b.col6 (+) line is extracted with b.col [1,2,3] as NULL values. Try to remove the (+) sign b.col6 and test.
with t as)
Select 111 col1, col2 'aaa', 'ABC' col6 123 header of all the double union
Select 222 'bbb', 'DEF' col6, 123 double header
)
q as (select 123 double header)
Select A.COL1, A.COL2, A.COL6
B.COL1, B.COL2, b.COL6
q.header
T a
t b
q
where a.col6 (+) = 'ABC '.
and b.col6 (+) = "DEF."
and q.header = a.header (+)
and q.header = b.header (+)

Problem with a simple integral
Hi all
I have 2 problems with a simple integral, and I do not understand how the first HP solves.
My first problem is that if I add a constant before my variable, the answer becomes really weird.
My second problem is that if I just change one letter (q becomes Q), the answer changes completely.
I am attaching a picture of the calculations so that you can understand my problem.
Thank you very much for your help
Kind regards
Xavier
When you type wx you now have a variable named "wx" - not w * x which is what I suspect you intend. You must manually add a multiplication between them.
When you use the Q, you are actually using the predefined global real variable that is most likely the value 0. If you've stored 2 in Q, I suspect that you'll get a different result. Remember that all variables in capital letters from A to Z and THETA and already defined as real numbers. VARS-> HOME-> REAL-press and you will see them.

Hello
I created two very simple tables for this exercise. I don't know if I can do this with a simple query, or must use pl/sql.
I want to join primary_table secondary_table of SSNand list the fields of primary_table, but only if the join returns only a line.
In other words, I would like to create a list of data primary_table for primary_table lines that have only one line on the secondary table.

Pool pane there problem with long sql query?
Hello
I use Jdeveloper 11.1.2.2.0
In the application I'm developing, there is a long sql query to call (it's a function from a package, which may take a few minutes to run) and I want to display a progress bar for the user.
The progress bar component is a "progress indicator" and the percentage of achivement is refreshed by a component 'pool' with 1-second interval.
The two components are connected in a javabean.
The function with the sql query is the javabean too.
To run the sql query that is long on background I am calling from a thread, and the pool component get the advancement of the percentage of a pipe filled with the sql function.
If the function to run is just a long loop of java operations the progress bar works fine, but if I put my long sql query instead, stop listener pool should be performed to stop long, s sql queryo progress are updated only at the end of the long sql query.
You have any ideas?
Thank you
Thanks for your replies. Unfortunately, it was not the solution to my case, sql procedures to block the entire application while ADF awaits them at the end...
To solve my problem, I finally used a PL SQL Job to call my sql procedure (dbms_job.submit).
The application is released right after the call and the component of the pool is not more secure!

Problem with REGEXP_SUBSTR related query.

I need the output in 2 rows in this format:

But I'm not able to get the "POINT OF SALE" in the output due to space, or perhaps another reason. Anyone can correct my query?
So, you want something like that?

Problem with the input query mode. FRM 41009, 40301
Hi all
I have a problem with the mode of input query. What can I say, I'm in the mode of input query, and I click on a button. I get the error THAT FRM-41009 displayed.
Now, I've wanted handled. So I created a trigger of error in order to handle the error.
IF ERR_CODE = 41009 THEN
NULL;
END IF;
A problem is that when you use the null value, it will not terminate the mode of input query, and then I get frm-40301 error.
Second, it's that I can't use exit_form in a trigger of the error.
I am aware that I can press F4 to exit this mode, but I don't want to do whenever I'm sure I'll get the user complaints.
Another solution would be to put the following code in the trigger when key pressed for each button in the form:
If: system.mode = "ENTER-QUERY" then
exit_form;
end if;
But I don't want to reproduce this code in my form.
Please can you give me an idea how to handle this correctly?
Thank you
Michael
PS: Version of the form = > ORACLE FORMS 10g (Forms [32 bit] Version 10.1.2.3.0)I have a problem with the mode of input query. What can I say, I'm in the mode of input query, and I click on a button. I get the error THAT FRM-41009 displayed.
What is the code in the trigger of your button When-Button-Pressed (WBP)? Maybe you should check to see if the form is in the Mode query in your WBP rather than try and remove the error? In other words, eliminate error - do not delete it. :)
If you want instead to remove the error, there is a technique to built-ins call restricted to a trigger that does not allow them. Do this by the use of a millisecond zero Timer. For example:
/* Sample On-Error Trigger */ DECLARE n_err_cd NUMBER := ERROR_CODE; t_on_error TIMER; ZERO NUMBER := 0; BEGIN IF ( n_err_cd = 41009 ) THEN /* Create Timer to execute Exit_Form() */ /* to Cancel Query-Mode. */ t_timer := Create_Timer('ON_ERROR', ZERO, NO_REPEAT); ELSE /* Handle all other errors here... */ END IF; END;/* Sample When-Timer-Expired Trigger */ DECLARE v_Timer VARCHAR2(30); BEGIN v_timer := Get_Application_Property(TIMER_NAME); IF ( v_timer = 'ON_ERROR' ) THEN /* Notice, the timer name is case sensative! */ Exit_Form; END IF; END;I am aware that I can press F4 to exit this mode, but I don't want to do whenever I'm sure I'll get the user complaints.
Well, it's just standard features of Oracle Forms. If you switch the Mode request form - you must run a query or cancel the query Mode! This is how it works. Your users need to understand that and accept it - just as they accept the functional also for other programs. ;) Another option would be to add a "Cancel request" button to your form and make it so it is enabled only when the form is placed in Query Mode. Just a thought...
I personally prefer to prevent the occurrence of an error rather than remove the error. :)
I hope this helps.

problems with basic spatial query
I am trying to learn Oracle Spatial, in collaboration with 11 g R2 and georeferenced 3D data (specifically buildings describing data in a city).
But I'm unable to get a basic query to work on my dataset (he works for the example in the book), and I'm doing it exactly as is done in the space for 11 g Developer Guide.
To learn how queries work, I implemented the cola_markets tables in the documentation, makes manual registration in the view user_sdo_geom_metadata and created the index. Having done this, I can run the following simple query (as well as others in the manual) on the book tables:
SELECT SDO_GEOM. SDO_DISTANCE (c_b.shape, c_d.shape, 0.005)
OF cola_markets c_b, c_d cola_markets
WHERE c_b.name = 'cola_b' AND c_d.name = 'cola_d ';
but when I try to do the same thing on my own paintings (created from citygml data), I get an error. There is the difference that the data is 3D, and that the index was created with no PARAMETERS (...), is therefore just 2D. But still I do not understand why the following query does not work:
SELECT SDO_GEOM. SDO_DISTANCE (c_w.envelope, c_b.envelope, 0.0005)
OF cityobject c_w,.
cityobject c_b
WHERE c_w.id = 50025
AND c_b.id = 50018;
The id for the buildings is valid, and I used the same tolerance used by software which has set up the database.
Here is the error I get in SQL Developer:
ORA-29532: Java call terminated by eception Java exception: java.lang.Exception: 54535
ORA-06512: at the 'MDSYS. SDO_3GL', line 637
ORA-06512: at the 'MDSYS. SDO_GEOM", line 1973
ORA-06512: at the 'MDSYS. SDO_GEOM", line 1990
29532 00000 - "Java call terminated by eception Java exception: %s."
* Cause: A mistake or a Java exception has been reported and could not be
solved by Java code.
* Action: Modify Java code, if this behavior is not expected.
So, thinking it could have something to do with the fact that it's a Java interface, I also tried to run from the command-line SQL/PL and get essentially the same thing:
ERROR on line 1:
ORA-29532: Java completed by eception Java exception appeal:
java.lang.Exception: 54535
ORA-06512: at the 'MDSYS. SDO_3GL', line 637
ORA-06512: at the 'MDSYS. SDO_GEOM", line 1973
ORA-06512: at the 'MDSYS. SDO_GEOM", line 1990
Any ideas why it does not work?54535 error means that the geometry data are not valid.
If you run validate_geometry_with_context on the data to check for errors and correct the data first.Siva

Problem with users simple Javascript running in an Active Directory environment
I support the local government environment.
After the latest updates for firefox 25.0.1 and Java 7 update 45 we are facing a lot of difficulties to access the sites provided by the central Government.
In some cases, the problems are solved by re - install java or that allow plugins to run.
In a particular case, we can access all the features (same photos and links to java scripts) to a site by using an administrator account, but cannot use a simple user. Activation of java deployment toolkit and Java (TM) platform plugins for the site did not work.
Computers face the problem to run Windows XP Pro + SP3.The same issue does not appear when you run google chrome...

Problem with pseudo-HIERARCHICAL query
Hi all
I'm writing a piece of SQL to validate the check digit in wines
(http://en.wikipedia.org/wiki/Vehicle_identification_number#Check_digit_calculation)
using
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bi
PL/SQL Release 10.2.0.5.0 - Production
The logic in the wikipedia article can be encapsulated as follows:
I can easily get the check digit for a WINE of the following logic:with val as (select '0' ch, 0 val from dual union all select '1', 1 from dual union all select 'A',1 from dual union all select 'J',1 from dual union all select '2',2 from dual union all select 'B',2 from dual union all select 'K',2 from dual union all select 'S',2 from dual union all select '3',3 from dual union all select 'C',3 from dual union all select 'L',3 from dual union all select 'T',3 from dual union all select '4',4 from dual union all select 'D',4 from dual union all select 'M',4 from dual union all select 'U',4 from dual union all select '5',5 from dual union all select 'E',5 from dual union all select 'N',5 from dual union all select 'V',5 from dual union all select '6',6 from dual union all select 'F',6 from dual union all select 'W',6 from dual union all select '7',7 from dual union all select 'G',7 from dual union all select 'P',7 from dual union all select 'X',7 from dual union all select '8',8 from dual union all select 'H',8 from dual union all select 'Y',8 from dual union all select '9',9 from dual union all select 'R',9 from dual union all select 'Z',9 from dual) ,weight as (select 1 pos, 8 weight from dual union all select 2, 7 from dual union all select 3, 6 from dual union all select 4, 5 from dual union all select 5, 4 from dual union all select 6, 3 from dual union all select 7, 2 from dual union all select 8, 10 from dual union all select 9, 0 from dual union all select 10, 9 from dual union all select 11, 8 from dual union all select 12, 7 from dual union all select 13, 6 from dual union all select 14, 5 from dual union all select 15, 4 from dual union all select 16, 3 from dual union all select 17, 2 from dual)
which produces:,vm as (select row_number() over(partition by vin order by level) rn , substr(vin, level,1) v , vin from (select 'ZAR91600006043427' vin from dual ) connect by level <= length(vin)) select vin , mod(sum(checksum),11) calculated_check , substr(vin,9,1) existing_check , regexp_instr(substr(vin,9,1),mod(sum(checksum),11)) correct from (select val.val * weight.weight checksum ,vm.vin from vm join val on (val.ch = vm.v) join weight on (weight.pos = vm.rn) order by vm.rn) group by vin;
However, I am having a little problem when I try to combine several wines of a table which I want to do rather than calculate each wine by programming:VIN CALCULATED_CHECK EXISTING_CHECK CORRECT ZAR91600006043427 4 0 0
This, for example, produces a line for each letter of the wine ready to match with the other two CTES:
I want ideally is a line for each character of each WINE. but this:with vehicle as (select 1000 as vehicle_id, 'ZAR91600006043427' as vin from dual union all select 1001, 'XXX91600006043427' from dual) select level , substr(vin, level,1) v , vin from (select * from vehicle where vehicle_id = 1000 ) connect by level <= length(vin);
product 262142 lines!with vehicle as (select 1000 as vehicle_id, 'ZAR91600006043427' as vin from dual union all select 1001, 'XXX91600006043427' from dual) select level , substr(vin, level,1) v , vin from (select * from vehicle where vehicle_id in (1000,1001) ) connect by level <= length(vin);
and adding
just reduced to 131070 lines...where vin = prior vin
place a different one on the SQL produced the result that I want, but it is not scalable product lines by adding a third vehicle are exponentially more than two.
so, in short: what is happening with my connect by statement that I'm missing?Hello

Whenever you want to debug a CONNECT BY query, put SYS_CONNECT_BY_PATH in the SELECT clause, to see how the lines are related.
We will also cut the sting down to only 3 characters, in order to make things faster and easier to read and add ROWNUM just to make it easier to talk about the results:with vehicle as (select 1000 as vehicle_id, 'ABC' as vin from dual union all select 1001, 'XYZ' from dual) select level , substr(vin, level,1) v , vin , sys_connect_by_path ( vin , ',' ) AS path_3 , sys_connect_by_path ( substr (vin, level, 1) , ',' ) AS path_1 , ROWNUM from (select * from vehicle where vehicle_id in (1000,1001) ) -- where vin = PRIOR vin connect by level <= length(vin);Output:
` LEVEL V VIN PATH_3 PATH_1 ROWNUM ---------- ---- --- -------------------- ---------- ---------- 1 A ABC ,ABC ,A 1 2 B ABC ,ABC,ABC ,A,B 2 3 C ABC ,ABC,ABC,ABC ,A,B,C 3 3 Z XYZ ,ABC,ABC,XYZ ,A,B,Z 4 2 Y XYZ ,ABC,XYZ ,A,Y 5 3 C ABC ,ABC,XYZ,ABC ,A,Y,C 6 3 Z XYZ ,ABC,XYZ,XYZ ,A,Y,Z 7 1 X XYZ ,XYZ ,X 8 2 B ABC ,XYZ,ABC ,X,B 9 3 C ABC ,XYZ,ABC,ABC ,X,B,C 10 3 Z XYZ ,XYZ,ABC,XYZ ,X,B,Z 11 2 Y XYZ ,XYZ,XYZ ,X,Y 12 3 C ABC ,XYZ,XYZ,ABC ,X,Y,C 13 3 Z XYZ ,XYZ,XYZ,XYZ ,X,Y,Z 14 14 rows selected.There is no START WITH clause, so it will start by each of the 2 rows. It is very good; Take the first case of 'ABC'.
Level = 1, we have row "ABC", so the substring added to this level is 'A'
The lines are connected to this line to LEVEL = 2? All rows that satisfy the condition of LEVEL<= length="" (vin),="" which,="" in="" this="" sample="" set,="" means="" both="" rows.="" let's="" take="" 'abc'="" first,="" which="" is="" what="" happened="" on="" the="" line="" where="" rownum="">
The lines are connected to this line (the line at the end of the path_3 ", ABC, ABC' ') = 3 level? All rows that satisfy the condition of LEVEL<= length="" (vin),="" which,="" in="" this="" sample="" set,="" means="" both="" rows.="" let's="" take="" 'abc'="" first,="" which="" is="" what="" happened="" on="" the="" line="" where="" rownum="">
So far, so good; the results were exactly what we wanted. But here's where it won't.
The lines are connected to the line at the end of the path ", ABC, ABC, ABC' level = 4?" All rows that satisfy the condition of LEVEL<= length="" (vin),="" which,="" in="" this="" sample="" set,="" means="" no="" rows.="" so="" let's="" back="" up="" the="" tree="" and="" see="" if="" any="" of="" the="" nodes="" we've="" already="" vistited="" has="" any="" other="" children.="" we="" back="" up="" to="" the="" row="" where="" path_3=',ABC,ABC' does="" 'abc'="" have="" any="" other="" children="" (that="" is,="" rows="" that="" meet="" the="" condition="" 3="">< length="" (vin)?="" yes,="" 'xyz'="" meets="" that="" condition,="" so="" 'xyz'="" is="" a="" child="" of="" 'abc',="" and="" we="" get="" the="" output="" row="" where="" rownum="">A CONNECT BY query WHERE clause is applied after the CONNECT BY is done. Adding a WHERE clause only deletes the rows from the result set once they have been generated. If we have a comment the WHERE clause above, the results are:
` LEVEL V VIN PATH_3 PATH_1 ROWNUM ---------- ---- --- -------------------- ---------- ---------- 2 B ABC ,ABC,ABC ,A,B 1 3 C ABC ,ABC,ABC,ABC ,A,B,C 2 3 Z XYZ ,ABC,XYZ,XYZ ,A,Y,Z 3 3 C ABC ,XYZ,ABC,ABC ,X,B,C 4 2 Y XYZ ,XYZ,XYZ ,X,Y 5 3 Z XYZ ,XYZ,XYZ,XYZ ,X,Y,Z 6Better, but it is still bad. All the 14 ranks were always generated, and then some of them have been excluded by the WHERE clause.
Why the lines like the one with ROWNUM = included 3? Because the WHERE 'wine = wine PRIOR' condition is true: on this line, the wine is "XYZ", and wine PRIOR is also "XYZ". The status of research only in the last 2 levels. (PREREQUISITE may only be 1 level.) It does not matter that, earlier in the path, there is a knot where wine! = wine BEFOREHAND; This condition applies only to the finished result set. So the output row with path_3 =', ABC, XYZ "was excluded the result defined by the WHERE clause, but the descendants of this line can remain.Moral: If you do a query CONNECT BY and provided to connect BY is 'LEVEL '.<= x",="" then="" the="" table="" had="" better="" have="" only="" one="">
Odie showed how to use CONNECT BY in this problem, by making the relative to the double CONNECT BY and joining your table of multiple row results. -
Problems with the simple serial communication.
I followed a tutorial online to start learning basic communication series. The involved tutorial shorting pins 1 and 3 on port 1 Comm and write a simple program (attached). I've edited it a bit, the program to see varied results I get when trying to write and read a simple sentence via a serial port.
Could someone explain what causes the kind of result shown in "Serial Comm example.png"? I think it has to do with timing. Why would be transmitted only the parts of the sentence?
Thank you
Sarah

What should be pins 2 and 3? On a standard serial port DB-9, pin 2 is the receive and pin 3 is the transmission.
Now for your code...
1. move the Serial Port to be before the loop to set it up. Simply configure the port once.
2. close the port after the loop.
3. managing your error after closing.
4 stop your loop on an error or the stop button has been pressed. You will need a RC in there.
5. no need to Flush Buffer function. Remove it.
6. using the bytes to the Port is a dangerous thing. It introduced all kinds of race conditions that are interesting. Instead, say VISA reading to read the number of bytes that you expect to read.
6a. Moreover, don't forget to send a character to end of line at the end of your data and all the number of bytes to read something a lot more than you ever expect read. The VISA read will stop reading when he a) sees the number of bytes, it was said to read, b) sees the stop character (currently enabled and set to a line break, which is part of the end of line), or c) the time-out occurs. Whichever comes first.
7. with 6, the wait is no longer necessary.
