SQL query help with CASE
Hi All,
I have 2 tables like below. now i have a requirement which i need to do it in CASE OR DECODE. because i have to implement this logic IN SELECT STATEMENT for a column.
In table T1 if Lang = 1 and State = 'P' then display Lang = 'english' in table T2(which is Lang=2 in table T1) Or else display null.
Can we do this logic using CASE or DECODE? pls help
T1
Lang State
1 P
2 N
T2
Lang Dscr
1 central
2 english
Something like this ?
SQL> ed
Wrote file afiedt.buf
1 WITH t1 AS (SELECT 1 lang, 'P' STATE FROM DUAL UNION ALL
2 SELECT 2 lang, 'N' STATE FROM DUAL
3 )
4 , t2 AS (SELECT 1 lang, 'central' dscr FROM DUAL UNION ALL
5 SELECT 2 lang, 'english' dscr FROM DUAL
6 )
7 SELECT t1.lang,t1.state,CASE
8 WHEN t1.lang=1 AND t1.state='P'
9 THEN (SELECT t2.lang FROM t2 WHERE dscr='english')
10 ELSE NULL
11 END "lang"
12* FROM t1

How to numberformat when using sql:query alogn with c:forEach JSTL tags
Is there anyway to format the numeric values returned from the database when using <sql:query> alogn with <c:forEach> tags
Here is my jsp code
<sql:query..../>
<c:forEach var="row" items="${queryResults.rows}">
<tr>
<td><c:out value="${row.COL1}" /></td>
<td><c:out value="${row.COL2}" /></td>
</tr>
</c:forEach>
Col1 values are numeric without any formats Eg: 1000, 10000, 1000000 etc.
how can i format them to 1,000 , 10,1000 , 100,000 etcIt is polite to mention what your answer was. These posts are not just here for you to ask questions, but to be used as a resource for other people to find answers. Saying "I solved it" with no details helps noone.
I presume you discovered the JSTL <fmt:formatNumber> tag? -
Hi Gurus,
Can someone please help me out.
I've a below tables.
1) tbl_link --> this table contains information at profile level
2) tbl_summary --> this table contains summary at parent profile level derived from tbl_link table
One parent profile contains multiple child profiles and each child profile links to a code (which is B, W, G or P) and the code is linked to a category (i.e. ONL and OFL). In this case code B is linked to category 'ONL' and codes W,G,P linked to OFL category.
ONL category needs 100 points. If it don't have enough points then i need to borrow from OFL category which i'm doing and populating into tbl_summary table at parent profile level.
Now i need to insert data into tbl_link table at profile level with howmany points used, expired based on tbl_summary table. Rule is at the end of month if we add points for each profile in tbl_link table it should come as 0.

SQL Query Help - Is this possible or impossible????
Hi guys,
I need help with an SQL query that I'm trying to develop. It's very easy to explain but when trying to implement it, I'm struggling to achieve the results that I want.....
For example,
I have 2 tables
The first table is:
1) COMPANY create table company (manufacturer varchar2(25),
date_established date,
location varchar2(25) );My sample test date is:
insert into company values ('Ford', 1902, 'USA');
insert into company values ('BMW', 1910, 'Germany');
insert into company values ('Tata', 1922, 'India');The second table is:
2) MODELS create table models (manufacturer varchar(25),
model varchar2(25),
price number(10),
year date,
current_production_status varchar2(1) ) ;My sample test data is:
insert into models values ('Ford', 'Mondeo', 10000, 2010, 0);
insert into models values ('Ford', 'Galaxy', 12000, 2008, 0);
insert into models values ('Ford', 'Escort', 10000, 1992, 1);
insert into models values ('BMW', '318', 17500, 2010, 0);
insert into models values ('BMW', '535d', 32000, 2006, 0);
insert into models values ('BMW', 'Z4', 10000, 1992, 0);
insert into models values ('Tata', 'Safari', 4000, 1999, 0);
insert into models values ('Tata', 'Sumo', 5500, 1996, 1);
insert into models values ('Tata', 'Maruti', 3500, 1998, 0);And this is my query:
SELECT
com.manufacturer,
com.date_established,
com.location,
DECODE(nvl(mod.current_production_status, '0'), '0', '-', mod.model),
DECODE(nvl(mod.current_production_status, '0'), '0', '-', mod.price),
DECODE(nvl(mod.current_production_status, '0'), '0', '-', mod.year),
mod.current_production_status
FROM
company com,
models mod
WHERE
mod.manufacturer = com.manufacturer
and com.manufacturer IN ('Ford', 'BMW', 'Tata')
and mod.current_production_status IN (1,0)
ORDER BY
mod.current_production_status DESCWhat I want the query to output is this:
com.manufacturer com.date_established com.location mod.model mod.price mod.year mod.current_production_status
Ford 1902 USA Escort 10000 1992 1
BMW 1910 Germany - - - 0
Tata 1922 India Sumo 5500 1998 1If current_production_status is 1 it means this particular model has been discontinued
If current_production_status is 0 it means the manufacturer does not have any discontinued models and all are in procuction.
The rule is only one record per manufacturer is allowed to have a current_production_status of 1 (so only one model from the selection the manufactuer offers is allowed to be discontinued).
So the query should output the one row where current_production_status is 1 for each manufacturer.
If for a given manufacturer there are no discontinued models and all have a current_production_status of 0 then ouput a SINGLE row that only includes the data from the COMPANY table (as above). The rest of the columns from the MODELS table should be populated with a '-' (hyphen).
My query as it is above will output all the records where current status is 1 or 0 like this
com.manufacturer com.date_established com.location mod.model mod.price mod.year mod.current_production_status
Ford 1902 USA Escort 10000 1992 1
Tata 1922 India Sumo 5500 1998 1
Ford 1902 USA - - - 0
Ford 1902 USA - - - 0
BMW 1910 Germany - - - 0
BMW 1910 Germany - - - 0
BMW 1910 Germany - - - 0
Tata 1922 India - - - 0
Tata 1922 India - - - 0However this is not what I want.
Any ideas how I can achieve the result I need?
Thanks!

and com.manufacturer = 'Ford'will be dependent on front end user input....
When I run the query above I get all the rows where current_production_status is either 1 or 0.
I only require the rows where current_production_status is 1.
So if I amend it to look like this:
and mod.current_production_status = 1This works....
BUT if a user now passes in more than one manufacturer EG:
and com.manufacturer IN ('Ford', 'BMW')The query will only return the one row for Ford where current_production_status is 1. However because BMW has no models where current_production_status is 1 (all 3 are 0), I still want this to be output - as one row....
So like this:
com.manufacturer com.date_established com.location mod.model mod.price mod.year mod.current_production_status
Ford 1902 USA Escort 10000 1992 1
BMW 1910 Germany - - - 0So (hopefully you understand), I want both cases to be catered for.....whether a user enters one manufacturer or more than one...
Thanks you so much!
This is really driving me insane :-( -
I'm having trouble with an SQL query. I've created a simple logon page wherein a user will enter their user name and password. The program will look in an Access database for the user name, sort it by Date/Time modified, and check to see if their password matches the most recent password. Unfortunately, the query returns no results. I'm absolutely certain that I'm doing the query correctly (I've imported it directly from my old VB6 code). Something simple is eluding me. Any help would be appreciated.
private void LogOn() {
//make sure that the user name/password is valid, then load the main menu
try {
//open the database connection
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection("jdbc:odbc:LawOffice2000", "", "");
Statement select = con.createStatement();
String strTemp = "Select * From EMPLOYEES Where INITIALS = '" + txtUserName.getText() + "' Order By DATE Desc, TIME Desc";
ResultSet result = select.executeQuery(strTemp);
while(result.next()) {
if (txtPassword.getPassword().toString() == result.getString("Password")) {
MenuMain.main();
else {
System.out.println("Password Bad");
System.out.println(txtUserName.getText());
System.out.println(result.getString("Password"));
break; //exit loop
//close the connection
con.close(); }
catch (Exception e) {
System.out.println("LawOfficeSuite_LogOn: " + e);
return; }
}The problem is here: "txtPassword.getPassword().toString() == result.getString("Password"))"
Don't confuse String's equals() method with the equality operator '=='. The == operator checks that two references refer to the same object. If you want to compare the contents of Strings (whether two strings contain the same characters), use equals(), e.g. if (str1.equals(str2))...
Example:String s1 = "foo";
String s2 = new String("foo");
System.out.println("s1 == s2: " + (s1 == s2)); // false
System.out.println("s1.equals(s2): " + (s1.equals(s2))); // trueFor more information, check out Comparison operators: equals() versus == -
SQL query slow with call to function
I have a SQL query that will return in less than a second or two with a function in-line selected in the "from" clause of the statement. As soon as I select that returned value in the SQL statement, the statement takes from anywhere from 2 to 5 minutes to return. Here is a simplified sample from the statement:
This statement returns in a second or 2.
select A.pk_id
from stu_schedule A, stu_school B, stu_year C, school_year D,
(select calc_ytd_class_abs2(Z.PK_ID,'U') ytd_unx
from stu_schedule Z) II
where B.pk_id = A.fk_stu_school
and C.pk_id = B.fk_stu_year
and D.pk_id = C.year
and D.school_year = '2011';
if I add this function call in, the statement runs extremely poor.
select A.pk_id,
II.ytd_unx
from stu_schedule A, stu_school B, stu_year C, school_year D,
(select calc_ytd_class_abs2(Z.PK_ID,'U') ytd_unx
from stu_schedule Z) II
where B.pk_id = A.fk_stu_school
and C.pk_id = B.fk_stu_year
and D.pk_id = C.year
and D.school_year = '2011';
Here is the function that is called:
create or replace FUNCTION calc_ytd_class_abs2 (p_fk_stu_schedule in varchar2,
p_legality in varchar2) return number IS
l_days_absent number := 0;
CURSOR get_class_abs IS
select (select nvl(max(D.days_absent),'0')
from cut_code D
where D.pk_id = C.fk_cut_code
and (D.legality = p_legality
or p_legality = '%')) days_absent
from stu_schedule_detail B, stu_class_attendance C
where B.fk_stu_schedule = p_fk_stu_schedule
and C.fk_stu_schedule_detail = B.pk_id;
BEGIN
FOR x in get_class_abs LOOP
l_days_absent := l_days_absent + x.days_absent;
END LOOP;
return (l_days_absent);
END calc_ytd_class_abs2;Query returns anywhere from 6000 to 32000 rows. For each of those rows a parameter is passed in to 4 different functions to get ytd totals. When I call the functions in the in-line view but do not select from them in the main SQL, the report (oh, this is Application Express 4.0 interactive reports, just an FYI) runs fast. The report comes back in a few seconds. But when I select from the in-line view to display those ytd totals, the report runs extremely slow. I know there are the articles about context switching and how mixing SQL with PL/SQL performs poorly. So I tried a pipeline table function where the function for the ytd totals populate the columns of the pipeline table and I select from the pipeline table in the SQL query in the interactive report. That seemed to perform a little worse from what I can tell.
Thanks for any help you can offer. -
SQL Query if or case omit fields but not line.
I have the below SQL Query my goal is to not show Aging or Storage Date if QTY is greater than 0.
I know I can omit the line but I still want to show just not those two fields is this possible?

This is what I'm looking for:
Work Smarter Not HarderAre you working with OracleSQL, There is no sysdate in SQL Server.
Select sl.SKU, sl.LOC,

Hi,
I was wondering if I could have some help with the query I have below for this general data set, please? I need to do it in a single SQL statement. We're currently running Oracle 10g. The piece I'm struggling with is identifying that the person has all the items in a collection and to include the collection in the resulting collection of items.
persons_items
person item
Ted cup
Ted saucer
Ted plate
Ted fork
Alice book
Alice thimble
Alice knife
Alice cup
Joe cup
Joe saucer
Joe plate
Joe knife
Joe fork
Joe spoon
Jessica spatula
Jessica dish
collections
collection_name item
crockery cup
crockery saucer

Query:
What single items and collections does Ted have? fork, crockery
What single items and collections does Alice have? book, thimble, knife, cup
What single items and collections does Joe have? crockery, cutlery
What single items and collections does Jessica have? spatula, dish
Thanks in advance.

Hello,
I need help with SQL... My database version is Oracle 10g Release 1.2.
I have two table with the exact same structure as follows...
create table t1(cust_id number(5), zone_number number(2), part_number varchar2(10))
create table t2(cust_id number(5), zone_number number(2), part_number varchar2(10))
I need a query that would give me two counts per pairs of customer between t1 and t2..
1.Count of part_number matches between the same zones in table 1 and table 2 for pairs of customers
for Customer 1 and 10 for zone 1 this total shoulb be 2 because between cust 1 and 10 for Zone 1 there are two part number matches A and B.
for Customer 1 and 10 for zone 2 this total shoulb be 0 because between cust 1 and 10 for Zone 2 there are no part number matches
for Customer 1 and 20 for zone 1 this total shoulb be 0 because between cust 1 and 20 for Zone 1 there are no part number matches
for Customer 1 and customer 20 zone 2 this total shoulb be 0 because between cust 1 and 20 for Zone 2 there is one part number matches , which is 'F'
for Customer 1 and customer 20 zone 3 this total shoulb be 0 because there is no zone 3 for Customer 1
same way
.. cust 2 and cust 10 Zone 1 counts and zone2 counts
.. for 2 and cust 20 zone 1, 2, and 3 counts
2. Total unique Part nmbers between the same zones for pairs of customers in table 1 and table2
for example
unique part numbers between cust 1 and 10 for zone 1 are A,B and C so the count should be 3
unique part numbers between cust 1 and 10 for zone 2 are B,F, D and E so the count should be 3
unique part numbers between cust 1 and 20 for zone 1 are A,B,C and G so the count should be 4
and so on so forth
insert into t1 values(1, 1, 'A')
insert into t1 values(1, 1, 'B')
insert into t1 values(1, 1, 'C')
insert into t1 values(1, 2, 'B')
insert into t1 values(1, 2, 'F')
insert into t1 values(1, 2, 'D')
insert into t1 values(1, 2, 'E')
insert into t1 values(2, 1, 'F')
insert into t1 values(2, 2, 'G')
insert into t1 values(2, 2, 'H')
insert into t2 values(10, 1, 'A')
insert into t2 values(10, 1, 'B')
insert into t2 values(10, 2, null)
insert into t2 values(20, 1, 'G')
insert into t2 values(20, 2, 'F')
insert into t2 values(20, 2, 'H')
insert into t2 values(20, 3, 'I')
insert into t2 values(20, 3, 'J')
My query result should be as follows...
cust1 cust2 zone pn_match_count total_unique_pn_count
1 10 1 2 3
1 10 2 0 4
1 20 1 0 4
1 20 2 1 5
1 20 3 0 2
2 10 1 0 3
2 10 2 0 2
2 20 1 0 2
2 20 2 1 3
2 20 3 0 2
I would really appreciate your help in writing this query.
Thanks in Advanceuser00 wrote:
No, that doesn't do it... I get no results with this query becuase the Cust_id in table 1 and table 2 are not the same.Yeah, I only realised that after I posted my query. I had interpreted pairs as "matching pairs" when what you meant was "permutations".

Thanks
Munis Warsi
nullSeriously, you post 750+ lines of unformatted SQL statement and a completely unreadable and unformatted explain plan and you expect people to be able to help with that?
From what I can see it looks like some sort of query against an Oracle APPS database, and there are numerous calls to PL/SQL functions in there, so you're creating a multitude of context switches between the SQL and PL engines... that's known to cause performance problems.
Take a read of the discussions linked in the FAQ: Re: 3. How to improve the performance of my query? / My query is running slow.
And also consider if your question would be better asked in the Oracle Apps forum space instead. -

AshutoshHi,
When you use something like "CONNECT BY LEVEL <= x", then at least one of the following must be true:
(a) the table has no more than 1 row
(b) there are other conditions in the CONNECT BY clause, or
(c) you know what you are doing.
To help see why, run this query
SELECT SYS_CONNECT_BY_PATH (dname, '/') AS path
, LEVEL
FROM scott.dept
CONNECT BY LEVEL <= 3
;and study the results:
PATH LEVEL

Query Help with Parent, Child, Child's Child

Query Help with Item Master & Warehouse Code
Forum,
I would like help with a query to identify any items within a database where a particular warehouse code does NOT exist against it. At present I have the following:
select T0.ItemCode, T1.WhsCode from OITM T0
INNER JOIN OITW T1 on T0.ItemCode = T1.ItemCode
where T0.ItemCode NOT IN ('WHS1')
This is returning all other instance and not just a list of item codes where 'WHS1' is missing from within the 'Stock Data' tab.
Thanks,
SarahHi Sarah...
Try This
SELECT T0.ItemCode, T0.ItemName, T1.WhsCode
FROM OITM T0 INNER JOIN OITW T1 ON T0.ItemCode = T1.ItemCode
WHERE T1.WhsCode not in ( 'WHS1')

ORA-06502 on 'SQL query' report with sort in 'Report Attributes'
Hi All,
We get the next error if we set sorting on a column in a 'Report' based on a 'SQL query'. Removing the sort, error disappeares:
failed to parse SQL query:
ORA-06502: PL/SQL: numeric or value error: NULL index table key value
Any suggestions?
ErikErik,
Thanks, this explains it. By specifying the request as part of your URL you run into the recently uncovered issue. The request you're setting is REMFROMLIST and ADD2LIST. You probably either have links that include those requests or you have branches where you specify them. Either way, in order to get reports sorting to work, you'll have to make sure that the request strings are not part of your URL. This is a work-around and the upcoming HTML DB patch release will solve this issue.
One way of avoiding this is to have computations on the previous pages that set a napplication level or page level item to the REMFROMLIST and ADD2LIST values and then you can use those items for your conditions that are currently evaluating those strings.
Hope this helps and sorry for the inconvenience,
Marc
