Select * from viewname where 1 1 gives records back

for one customer the following sql gives records back
select * from viewname where 1<>1
we asked the customer to send over the database to us but we can't reproduce this behaviour. We don't get any records. the problem is we don't have the same version of oracle they use 9.2.0.4 and we used 10.2.0.1. i can't download the 9i version anymore.
Does anybody know of a bug in oracle which can cause such behaviour or a setting which can correct this?

i suspect the customer would first want us to show that their version is the problem.It doesn't work like that. If your customer called Oracle Support and said... "we're experiencing problems and our database version is 9.2.0.4"... oracle would turn around and say "that version is no longer supported, please upgrade". If they insist on knowing that their version is the problem, then the answer is "yes, it's the problem, it has known bugs and newer versions are available that address thousands of issues since"
Using a query with "where 1 <> 1" as a condition that is bringing back results, is clearly wrong. You have clearly shown that in other more recent versions of the database it is working ok, therefore you have already proven that there is a bug in the version they are using.
They are suspecting our view has a design flaw. We have in our documentation stated requirements for our software are the 9 or 10 version of oracle or sql server. So for me there are a couple of possibilities:
-we try to reproduce the query on their database on the same oracle database version as they are using - problem is we don't have this exact same version and oracle does not have this version for download on their site anymore or so it seemsThat's because it's no longer supported. Any good software house will keep on top of it's customers to ensure they are upgraded in line with Oracle's ability to support. So, partially, it's your companies fault for saying you support version 9, when clearly you can't.
--i ask other more knowledgable people(hopefully this forum) who might know about such problems which might result in a correction in the customer oracle database configuration or know of a bug in the customers version which causes this behaviour.You'll be lucky to find people still using such an old version (you're talking a version that almost 10 years out of date). The best you can do is to log onto Oracle Support and search there for known issues... and the answer on those is likely to be a recommendation to patch or upgrade too.
-we change the queries to these views so they won't try to give back any records on their serverHow will you know unless you are able to test them?

Can I simulate SELECT * FROM TABLE WHERE ROW IN (1111,2222) using SQLJ

I have a fct like
public void fct(String inStr) {
String str = "SELECT * FROM TABLE WHERE ROW IN" + inStr;
// then I xecute the query using JDBC connection
But I want to do the same thisn using SQLJ like:
public void fct(String inStr) {
#sql [nctx] iter = { SELECT * FROM TABLE WHERE ROW IN :inStr}
When I run the second version and give a parameter like "(1111,2222)" it gives
ORA-01722: invalid number error.
Is there a way to give parameters to in clauses of SQLJ statements.
Thanks in regard.

This is a SQLJ FAQ. You can find the FAQ at:
http://technet.oracle.com/tech/java/sqlj_jdbc/htdocs/faq.html
Your question is addressed in the following section:
http://technet.oracle.com/tech/java/sqlj_jdbc/htdocs/faq.html#variablesizevaluelist
Note that that section has a typo. The lines:
? // populate mynumbers
#sql { SELECT * FROM tab WHERE col in (:(a[0]),:(a[1]),?};
should read:
... // populate mynumbers
#sql { SELECT * FROM tab WHERE col in (:(a[0]),:(a[1]),...};
By the way, with the next release SQLJ will support pasting in of dynamic SQL fragments. Then you'll be able to do pretty much what you are trying to accomplish here (albeit with slightly different syntax). Until then you'd have to use the workarounds from the FAQ.

Reason behind this query ,SELECT * FROM table WHERE 1 0

HEllo,
I would like to know the reason behind using this query ,
SELECT * FROM <table> WHERE 1 < 0
before executing the actual SQL query.
Is there any special reason or the JDBC receiver side is configured like that.
Is there any option to overcome this process like, can we remove this option or stop using this.
Why the JDBC adapter basically sending this query on the DB?
Thanks,
Soorya,

Hi,
if you run this query, you wont be able to see any records of the table.
SELECT * FROM <table> WHERE 1 < 0
if you run this query you will see all records
SELECT * FROM <table> WHERE 0 < 1
same with SELECT * FROM <table> WHERE 1=1
So you can check this out that whats happening in your code before executing actual query. just try to co-relate.

Select * from emp where ename=(procedure1(procedure2(procedure3)));

I have a big problem
I have to check the data for quality data
Lets say i have to check data in emp table
First i have to check whether the empno is of type number
     IF empno=number then
          if ename starts with a particualar format then
               ---printouts and this procedure goes on for about 10 coulumns
I have designed a hard coded procedure where I input table name and column name and the procedure does the checks and give out result
I have planned to call that procedures here for each checks
its like i make the procedure to execute and the procedure returns rowid of the correct data
now i have to apply the second procedure where input is all the rowids of previous procedure and it goes on
I even dont know whether procedure is correct or function is correct
Its like select * from emp where ename=(procedure1(procedure2(procedure3)));
each procedure's output is Rowids only which satisfy a particular format of data
Please explain me in details
Please please help me.

Nested calls are not the best of ideas. Ignoring that for a moment, there are a couple of ways to address this requirement in Oracle. One of these, and likely one of the more scalable ways, is to use Pipeline Table Functions.
The following code demonstrates the basics of this approach, using pipelined table functions to perform validation checks on data.

How do I do SELECT * FROM TABLE WHERE KEY IN ({list})?

The title says it all really.
Is there a reasonable performant way to perform the query
SELECT * FROM TABLE WHERE KEY IN ({list})where {list} is String []?
I am currently creating a PreparedStatement with a for loop like this StringBuffer sb = new StringBuffer ("SELECT * FROM TABLE WHERE ID IN (");
for (int ii=0;ii<keys.length;ii++) {
sb.append (keys [ii]);
if (ii != keys.length-1) sb.append (",");
sb.append (")");but this means that the prepared statement is created each time I call my method and so I'm not sure that the optimizer will find it easy to cope with. Is there a construction that I'm missing along the lines of SELECT * FROM TABLE WHERE KEY = ? where I can create the PreparedStatement once and just call setObject or something on it when the values in {list} change?

but this means that the prepared statement is created
each time I call my method and so I'm not sure that
the optimizer will find it easy to cope with.You are right, the optimizer won't find that easy to deal with (presuming that is even relevant for your driver/database.) But most optimizers won't do anything with statements that change and that is what you are doing.
You could create several prepared statements which have a common number of bind variables. For example 10 statements with from 1 to 10 bind values. This will work if most of the queries use those.

Is it possible to ... SELECT * FROM my_table WHERE ssn IN (..arraylist..) ?

Hi, I have a quick question I hope someone can help me with. I'm a student and what I'm looking for should be easy but I can't find any information on it.
Here's my code, it's probably self-explanatory but to clarify I'm trying to get a list of "Captains" in the order of who has the most wins.
The problem is that the database tables have thousands of "Captains" and I'm only supposed to look at 200 specific "Captains" which have their ssn in a specific arraylist and then return the top 80 "Captains" from that selection.
Something like this...
SELECT first 80 E.name, L.ssn, COUNT(L.wins) as Wins
FROM log L, employees E
where type matches "[Captain]"
and E.ssn = L.ssn
and L.ssn IN (...arraylist...) // How do I loop through the arraylist but still return a list of the top 80 winners?
group by E.name, L.ssn
order by Wins desc;
Should I start by taking the list of social security numbers from the arraylist and insert them into a temporary table and then use that temporary table to base my selection on?
For example:
int rows = 0;
PreparedStatement ps = conn.prepareStatement("INSERT INTO TEMP captainsTemp (ssn) VALUES(?)");
Iterator i = myArrayList.iterator();
while (i.hasNext())
     // Set the variables
     for (int pos = 1; pos <= 63; pos++)
          String s = (String)i.next();
          ps.setString(pos,s);
     // insert a row
     rows += ps.execute();
...and then below that I could use
"SELECT * FROM captains
WHERE ssn IN (SELECT * FROM captainTemp)..."
This looks like an ugly solution and I'm not sure if it works, sessionwise..
Everything's written in Java and SQL.
If you have any thoughts on this I would be most grateful.
I should add that this is NOT a school assignment but something I'm trying to figure out for my work...
Many thanks,
sincerely,
JT.

hi,
Ignore my previous response. Try out this one. It should help you.
Lets take the example of EMP table (in Oracle's SCOTT Schema). The following is the description of the table.
SQL> desc emp
Name Null? Type
EMPNO NOT NULL NUMBER(4)
ENAME VARCHAR2(10)
JOB VARCHAR2(9)
MGR NUMBER(4)
HIREDATE DATE
SAL NUMBER(7,2)
COMM NUMBER(7,2)
DEPTNO NUMBER(2)
SQL> select ename from emp;
ENAME
SMITH
ALLEN
WARD
JONES
MARTIN
BLAKE
CLARK
SCOTT
KING
TURNER
ADAMS
JAMES
FORD
MILLER
Say, the ArrayList contains 3 names CLARK,KING & MILLER. You want to loop through the ArrayList for the ENAME values.
First construct a string like below from the ArrayList.
"ename in 'CLARK' OR ename in 'KING' or ename in 'MILLER'";
Append this string to the normal SELECT Query
Query :
select ename from emp where ename in 'CLARK' OR ename in 'KING' or ename in 'MILLER'
Here you get the desired output & thats pretty fast because you just do it once !!!
SQL> select ename from emp where ename in 'CLARK' OR ename in 'KING' or ename in 'MILLER';
ENAME
CLARK
KING
MILLER
you can extend this to your Query also.
thanks,
Sriram

Firmware version is 2.1.7.1
What could have happenend?
With kind regards,

Hi, everything in the "Quick Reference" section should be commented out with ;
You should change those settings further down in the php.ini file.
Example:
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
display_errors = Off

Retrieve optimize: select * from tb where mdate sysdate

hi,
i wrote a simple statement :
select * from tb where mdate > sysdate;
it takes long time to return resultset.
when i use to_char() function,
select * from tb where to_char(mdate,'yyyy-mm-dd') >
to_char(sysdate,'yyyy-mm-dd');
it runs faster.
who can tell me why?
thanks.

Are you running each statement multiple times and averaging the results? If you run the date comparison once, then run the character comparison, it's likely that the data you want is already cached, so the secod statement may well return more quickly. If you average multiple runs, you can avoid this.

Select * from tbl where product like ('abc','def','rgh');

Hi Guys,
My requirement is I need to filter by providing date value with some of the porduct details and prod_id may differ with product like
prod_id product date
01 abc 01/2012
02 abc 02/2012
03 def 03/2012
How can we put multiple text conditions using LIKE operator in where clause of the sql query.
if we use union to combine all the sql queries, how can we filter by entering date value.
SQL>select * from tbl where product like ('abc','def','rgh');
Please provide any ideas on the same.
Thanks in advance!

thank's for your replay
i try make it string but do not success and i input the parameters from baking bean

sabcarina

ok thanks . like YOU said this worked:
String query= "SELECT * FROM MEMBERS WHERE M_ID >" + myvar;
So please i need to LEARN the need for single quotes in the SQL queries:
What is it used for and why ? i mean i know it is for Strings but why do we need to enclose these varnames in single quotes?
THANKS A MILLION

SELECT * FROM TESTTABLE WHERE ID IN (?)

Hi,
I have a query (SELECT * FROM TESTTABLE WHERE ID IN (?)) and I want to pass in parameter a list of values (an array or something like that) to put in my condition IN.
How can I do in java ? Is there something special in the PreparedStatement ? Or have I to use another statement ?
Thanks

Geoffrey,
You can formulate the sql query in the java side, and IN clause demands the arguements separates by commas,
So you can easily prepare that string by taking the values from the parameters and inserting into that String separated by commas.
Its better to that that operation in the java part rather than in the procedure if you are only running this query in that Procedure.
Thanks.

Newbie Select * FROM table where IF Numeric else something else

I have a text on a web page. If one can enter an EMPLOYID ( like 55 ) or
lastname like 'SMITH'.
I tried using INSTR and Substr but no avail.
Select *
from Atable
WHERE
IF SUBSTR(myfield,1,1)="0" OR
IF SUBSTR(myfield,1,1)="1" OR
etc.
EMPID=to_number(myfield)
ELSE
Upper(Lastname) like Upper(myfield)
Suggestions?
TIA
Steve

Yes myfield could be either "55" OR it could be "SMITH"
Otherwise I would have to have 2 textboxes on the web page.
One for EmployeeID and one for lastname.
Thanks.
Steve

Select * from viewname where 1 1 gives records back
