Oracle query help

This issue is no answer. (As supposed to Mark answered)

user5784286 , August 10, 2015 21:21

Hi all
I have the order by clause and the Description field gets data
like (shipping) and (shipping - Volumes traded) , but the
InStr, function cannot tell the difference between them and can not get good results

order by
DECODE (instr (Description, 'Shipping costs', 1), 1, 1, 3),
DECODE (instr (Description, ' delivery charges for ', 1), 1.2, 3).
DECODE (instr ("Description, ' delivery charges - the Volumes traded", 1), 1, 3, 3)

any help how to solve this problem

I expect results like this in order to

1 delivery charge

Delivery 2 to

3 delivery - traded volumes

example 1

1 delivery charge

Delivery 2 to

3 delivery - traded volumes

but my performance varies and I get

3 delivery - traded volumes

1 delivery charge

Delivery 2 to

example 2

1 delivery charge

Delivery charges 2 - traded volumes

My varies and I get

Delivery charges 2 - traded volumes

1 delivery charge

Hello

Your use of INSTR assumes that the string "delivery fees" always appears at the beginning of the string (INSTR returns 1 because that is where the search string is found to start)... Baring all in mind...

WITH the list in the FORM (SELECT "delivery Charge #1" ")	Description OF the dual UNION ALL
	SELECT "delivery fees".	Double UNION ALL
	SELECT "shipping for.	Double UNION ALL
	SELECT "shipping costs - negotiated Volumes."	Double UNION ALL
	SELECT "Shipping A in the beginning"	Double UNION ALL
	SELECT 'delivery charges against '.	OF the double
	)

SELECT description

LIST

In case of ORDERS description WHEN = "delivery charges - the Volumes negotiated" THEN 3

	Description WHEN AS "shipping costs for %.	THEN 2
	Description WHEN = "delivery fees".	THEN 1
	ANOTHER 99
	END;

DESCRIPTION

--------------------------------

Delivery charges

Delivery charges for

Delivery charges - traded Volumes

Delivery charges against

A delivery charge, not at the beginning

Delivery #1

Hierarchical Oracle query help needed - path between the crux of two brothers and sisters
I want to find the path between two nodes of oracle hierarchical Table.

Consider the following case-
NodeId - ParentId
=============
1 > > > > > > 0
2 > > > > > > 1
3 > > > > > > 2
4 > > > > > > 3
5 > > > > > > 0
6 > > > > > > 5
Here I want to query the database table that if there is a path between nodes 3 and 5?
The previous query you provided work upwards to the root node.

Here is my expected result, 3-> 2-> 1-> 0-> 5

Yet once if I have a query in the table to get the path between 1 and 3, I want to get out of the way - next
1-> 2-> 3

Therefore, the query works in both cases. Where ADI root can act as an intermediate or no node.

Can you please guide me how I can get it?

Thank you.

I think you want something like this:
```
WITH     bottom_up_from_src    AS
(
     SELECT     nodeid
     ,     parentid
     FROM     table_x
     START WITH     nodeid      = :src_nodeid
     CONNECT BY     nodeid   = PRIOR parentid
)
,     bottom_up_from_dst     AS
(
     SELECT     *
     FROM     bottom_up_from_src
    UNION ALL
     SELECT     parentid     AS nodeid
     ,     nodeid          AS parentid
     FROM     table_x
     WHERE     nodeid     NOT IN (
                                      SELECT  nodeid
                               FROM    bottom_up_from_src
                                  )
     START WITH     nodeid        = :dst_nodeid
     CONNECT BY     nodeid        = PRIOR parentid
)
SELECT      :src_nodeid || SYS_CONNECT_BY_PATH (parentid, '-->')     AS display_path
FROM       bottom_up_from_dst
WHERE       parentid     = :dst_nodeid
START WITH  nodeid     = :src_nodeid
CONNECT BY  nodeid     = PRIOR parentid
;
```
This will show how you can get it from: src_nodeid at dst_nodeid, moving to the top or to the bottom of a hierarchy at a time step. This will work regardless of the fact that
- : src_nodeid is the ancestor of the: dst_nodeid, or
- : src_nodeid is a descendant of: dst_nodeid, or
- both: src_nodeid and: dst_nodeid are the descendants of another node (e.g. 0).
I hope that answers your question.
If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0). It is always important, but particularly so with CONNECT BY queries, because each version since Oracle 7 had significant improvements in this area.

MySQL to Oracle query
Hello World ^^

I just downloaded Oracle XE and migrated my database from MySQL to Oracle successfully.
And I'm doing/reviewing my application now especially the query syntax.
I am facing a problem, I have a request in the form below in MySQL and it works fine but when I tried it at the Oracle XE database, it cannot run :( So I'm asking for help here, I have already searched on the internet but had no luck.

SELECT A.INVOICEDATE,
*@Step1:=cast (adddate (A.INVOICEDATE, A.TERMOFPAYMENT) as date) AS STEP1, *.
*@Step2:=if (@step1 > CURDATE (), A.TOTALAMOUNT, 0) AS STEP2, *.
*@step3:=if (@step2 <>0,0,IF(DATEDIFF(CURDATE(),@step1) < = 30, A.TOTALAMOUNT, 0)) AS step 3,
T_invoice FROM has
WHERE A.STATUS = 'Open'

I can conclude the problem is based on the variable declaration in Oracle, but I still can't understand.
What I do in MySQL, it's that I want to fill the variable with the expression/logic so I can use 'than' variable more later in the other part of the query output syntax.
I used variables to be filled by value due to I can't use / select ALIAS later in the other party.

So please help to convert to Oracle query syntax. Thank you.
Oracle and MySql are two different animals. You need to learn SQL and Oracle's PL/SQL.

Your SQL
```
SELECT A.INVOICEDATE,
@step1:=cast(ADDDATE(A.INVOICEDATE,A.TERMOFPAYMENT) as date) AS STEP1,
@step2:=IF(@step1>CURDATE(),A.TOTALAMOUNT,0) AS STEP2,
@step3:=IF(@step20,0,IF(DATEDIFF(CURDATE(),@step1)<=30,A.TOTALAMOUNT,0)) AS STEP3,
FROM t_invoice A
WHERE A.STATUS='Open' 
```
Can be writern as
```
select invoicedate,
       step1,
       step2,
       case when step2 = 0
            then case when sysdate-step1 <=30 then A.TOTALAMOUNT else 0 end
       end AS step3
  from (
         select A.invoicedate,
                A.invoicedate+A.termofpayment step1,
                case when (A.invoicedate+A.termofpayment) > sysdate then A.totalamount else 0 end as step2,
           from t_invoice A
          where A.status = 'Open'
       )

If you run this query in sql * plus you can declare a sql * more variable, assign a numeric value according to 'now' and use in your application, i.e.

SQL > variable NUMBER of SYSDATE_UTS;
SQL > exec SYSDATE_UTS: = (sysdate-to_date('19700101','yyyymmdd')) * 86400;

You would then call your request, referring to sql * more variable with a colon as SYSDATE_UTS prior to it (i.e.: SYSDATE_UTS)

Need help with oracle query

Hello
I have a customer as requirement below
We have the table header and contains data such as
ID, custname, socket
101, raju, 514
102, ratna, 12
103, rakesh, 16
104, joseph, 129
and we mappingtable like below as
sampval, socket
244094,512
244095,2
244096,4
244097,8
244098,16
244102,128
244103,1
If header.mapvalue is 514 analysis then it out on the mappingtable basis to be exported for a value of 244094. 244095.
Header.mapvalue is 12 parsing it out based on mappingtable to be exported for a value of 244096. 244097 and so on...
Could you please help me how to get the functionality in a database query.
Thanks in advance

Try to query below and let me know

SELECT id,

custName,

HT.mapvalue,

req_val

From ht header_tbl,

(SELECT SAMPVAL,

socket,

SUMVAL,

REQ_VAL

CASE

WHEN ((= LEVEL 2)

AND (socket = socket connect_by_root))

THEN socket

ANOTHER socket + connect_by_root socket

END as sumval,

CASE

WHEN ((= LEVEL 2)

AND (socket = socket connect_by_root))

THEN TO_CHAR (sampval)

Of OTHER TO_CHAR (CONNECT_BY_ROOT sampval

END AS req_val

A mapping

CONNECT BY LEVEL<=>

)

WHERE the lvl = 2

)

WHERE rn = 1

) qry_rslt

WHERE ht.mapvalue = qry_rslt.sumval;

An alternative with xmlagg, you can use this query to achieve your requirement

SELECT id, custname, RTRIM (xmlagg (xmlelement(e,mp.sampval||'|')). Extract ('//Text ()'),'| ') req_val

From header_tbl, mapping mp ht

WHERE mp.mapvalue = BITAND (mp.mapvalue, ht.mapvalue)

GROUP BY id, custname;

Hierarchical query help need to Oracle
Hello
I'm in a deep trouble.

I want to do a hierarchical query in my TreeView table in oracle. But I want that the query retrieves information path between two nodes.

Review the table below.

------------------------------------------------------
Node ID | Name of the node. ID of the parent
-----------------------------------------------------
1A 0
2 1
3C0
4 2
-----------------------------------------------------

What I want is that I'll give you 2 node id in the request. One is the source node and the other is the destination node.
so if I put 1 node and node 4, I want to be the output

1-> 2-> 4

I want just a return line. Or there may be several rows but stands only the node of this path.

1
2
4
----

This means that I don't want to node 3 in the search result.

More if I have the source as 4 node and the node of destination as 1 then I will also get an output of the query as below-
4-> 2-> 1

This means that the search for the query for the result in a way directional bi.

If anyone can give me some information about who it's going to be great for me.

Hello

Welcome to the forum!

Assuming you have 2 separate nodes: Node_A and: node_b, you can find the hierarchy from one to the other like this:
```
SELECT     SYS_CONNECT_BY_PATH (node_id, ',')     AS lineage
FROM     table_x
WHERE     node_id     IN (:node_a, :node_b)
AND     LEVEL     > 1
START WITH     node_id          IN (:node_a, :node_b)
CONNECT BY     parent_id     = PRIOR node_id
;
```
It will work if: the Node_A is an ancestor of the: node_b, or if: node_b is an ancestor of the: Node_A.
If is the ancestor of the other, then it will produce 0 rows.

The query above does not work for this case.

Want to get answers that work, or is it possible to get responses that cause errors?

Make sure that the INSERT statements you post too much work. Test (and, if necessary, correct) them before posting. All the instructions insert above have errors.

The query above (once you correct the spelling of PARTITION) returns all the lines after a date limit. It's always what you want, only the details of how calculated this date limit changed. In accordance with the new requirements, the closing date must be earlier than the actual lines dt_recv in there are not 2 (or more) with batch = 1 for any combination of (supplier_id, supplier_desc_id). All you have to do is change "r_num".<= 2"="" to="" "r_num="2" ,"="" when="" computing="" dt_cutoff,="" and="" return="" an="" impossiblly="" early="" date="" if="" there="" is="" no="" such="" row. ="" (i="" assume="" that="" dt_recv="" can="" not="" be="">

SELECT id, supplier_id, supplier_desc_id, batch, dt_recv

OF got_dt_cutoff

WHERE dt_recv > = dt_cutoff

If dt_recv can be NULL, it is a bit more complicated, but only a little. Post instructions INSERT (work) and outcomes if you would like to help with this scenario.

This sounds like a job for LISTAGG:

label

LISTAGG (comp_name, ',')

THE Group (ORDER BY ComputerName) AS value1

OF test1

GROUP BY label

;

If you would care to post CREATE TABLE and INSERT statements for your sample data, then I could test it.

Are you sure that the results you posted are what you want from data provided?

Is of the order of the elements in a significant list? In other words, when you say you want to get the results:

COMP1, COMP2

you'd be just as happy with

ORDI1, COMP2

? If the order is important, explains what this order.

SQL Query Help (not working not properly)

Hello everyone,
I use JDeveloper 12.1.2.0.0. I do a two-way communication using 3 tables, with links between them (and using schema HR).
In my example, I have something like:
Departments, employees, and the SalaryByJobs (I created this table where it shows a departmentd id, employee id, salary).
Whenever I click on one OR more departments, the employees up-to-date table by putting on the table, employees who belong to the selected department and the salaryByjob to put the jobs of the employees selected on the employees table.
So it's something like this:
The departments selected-> employees selected-> salarybyjbobs of these employees.
My query used (in the view) has the following code:
SELECT Employees.COMMISSION_PCT,
Employees.DEPARTMENT_ID,
Employees.EMAIL,
Employees.EMPLOYEE_ID,
Employees.FIRST_NAME,
Employees.HIRE_DATE,
Employees.JOB_ID,
Employees.LAST_NAME,
Employees.MANAGER_ID,
Employees.PHONE_NUMBER,
Employees.SALARY
Employees EMPLOYEES
WHERE (department_id IN (select * from THE (select cast (in_list(:variavel3) as mytableType) double) a))
Since I use the links, the employees table does not show anything at the beginning, so I added this to my query used to go: OR nvl(:variavel3,0) = 0
But now, whenever I try to select multiple lines, it gives me the invalid numbers and I don't understand why...
It's only one line of code and it is not in the bean.
Can someone help me?
PS - The bean will Department by Department, adds the departments with ',' and for each Department, gets employees who belongs to them.
My best regards,
Frederico Barracha.

The expression NVL (: variavel3, 0) = 0 is not correct. The data type of the return value of the NVL function is considered to be equal to the data type of the argument of 1 (that is, the data type of the variable binding: variavel3). You said that this variable contained a list separated by commas to ID, so the data type of the variable is VARCHAR2. As long as you compare the NVL expression of a number, you get 'Invalid number' exception, because Oracle expects a numeric data type on the left side of the comparison operator.

To avoid the exception "Invalid number", you can modify the expression by using one of the following options:

: variavel3 IS NULL

NVL (: variavel3, ' *') = ' *'

NVL (: variavel3, ' 0') = '0'

Option 1, so the simplest and clearest.

Please, help me in this scenario.
			 One option is to use the NLSSORT function. Most of the ASCII character set defines the sort lowercase before uppercase but EBCDIC kinds of lowercase before uppercase. So you can use
with t as)
Select the id "H58098", "ACETAMIDOHYDROXYPHENYLTHIAZOLE" union str double all the
SELECT id, ' 043994 ',' alloy. Mr. INTHICK' double str
)
SELECT id, str
t
NLSSORT order (str, 'NLS_SORT = EBCDIC')
;
ID STR
------ ------------------------------
043994 alloy. MR. INTHICK
H58098 ACETAMIDOHYDROXYPHENYLTHIAZOLE
Of course, if your strings can contain non-alphanumeric characters, you should check that the sort of EBCDIC order is acceptable for them as well. To check this, you can use something like
with t (str, ascii) as long as)
Select chr(level+32), level + 32 double connect by level<=>
)
Select str, ascii from t by NLSSORT (str, 'NLS_SORT = EBCDIC')
;
or simply do a search of the internet on EBCDIC. You can also substitute other kinds of language for EBCDIC and see if any of them meet your needs. See Appendix A of the Guide to support globalization for the list of valid values for NLS_SORT.
You say that you are on 11g - if you want to say 11.2.x, then you can use the listagg function to get a more compact view of the sort order:
with t (str, ascii) as long as)
Select chr(level+32), level + 32 double connect by level<=>
)
Select listagg (str) in the Group (order by NLSSORT (str, 'NLS_SORT = EBCDIC')) as EBCDIC_order
t
;

Grouping Query Help
I need help in writing a query. The data that I now contains three columns. The values in the first column have duplicate, and the 2nd column entries. The third is unique. Here is an example of the data that I have today:

Thanks for your help
Hello

Your front end that can probably not for you.
In SQL * Plus, for example:
```
BREAK  ON column1    ON column2

SELECT    column1, column2, column3
FROM      table_x
ORDER BY  column3
;
```
If you havd do in SQL, here's one way:
```
SELECT       CASE
         WHEN ROW_NUMBER () OVER ( PARTITION BY  column1
                          ORDER BY         column3
                        ) = 1
         THEN  column1

       END     AS col1
,       CASE
         WHEN ROW_NUMBER () OVER ( PARTITION BY  column2
                          ORDER BY         column3
                        ) = 1
         THEN  column1
,       END     AS col2
,       column3
FROM       table_x
ORDER BY  column3
;
```
I hope that answers your question.
If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.
Highlight a few places where the queries above are getting incorrect results and explain, using specific examples, how you get the results of the data provided in these places.
Always tell what version of Oracle you are using.

The output of the query (as above) must partially match the following query (a particular combination of CLO)

SELECT count (1)
TIBCO. TRANSACTION_HISTORY
WHERE TYPE = 'ShipmentConfirm '.
and APP in ("SAPPI") and INTERVENE ('9332')

My Questions:

1.*There are indexes on all 3 APP passes it's IE, STEP and TYPE *. I don't want a FULL table Scan (as one would use the index). Can change us the query / use of indices, etc. to make it faster?

2. is the right to approach? Would the use of the concat operator in the function decode work better for my needs?
Something like

Select decode (APP |) STEP, 'SAPP9332', 'X') of TRANSACTION_HISTORY where < COND >

If Yes can you please provide the query?

3. ANY other approach / request for my requirement.

Thanks in advance.

A full table scan might be the fastest way to get results. Do you have any reason to think that it would be faster to go through the index? How selective are the clues? In other words, what is the percentage of rows in the table correspond to each of the values in the WHERE clause?

2. is the right to approach?

It depends on what you're trying to do, which is not at all clear to me.

If you use this approach, look out for the problem Ab asse crevit . For example, if you have these 4 rows and 2 columns:
```
str1     str2
----     ----
(NULL)     FOO
F     OO
FO     O
FOO     (NULL)
```
There are 4 values of distict of str1 (counting NULL) and 4 separate values of str2, str1 but | str2 is the same for each of them. In the above example, it there is no way to know, just by looking at the concatenated string, including str1 and str2 ends begins. Maybe it's not the case for your specific data (for example, if the application is still exactly 5 characters long). otherwise, you may need to add some kind of delimiter, like this
```
app || '+' || step
```
where you know that '+' never occurs in one of these columns.

3. ANY other approach / request for my requirement.

CASES, as I mentioned in your previous message:
Decode the help function
and as you have used above.

In this thread, you said "I have to use the decode function. Why? It is a competition of school Etudieeo DECODE is explicitly required? Why you don't want in the best way, what that turns out to be?

Your WHERE clause:
```
AND APP IN ('SAPPI', 'SAPPI', 'SAPR3')
AND STEP IN ('9320', '9332', '1208')
```
admits 6 possible combinations of APA and step:
```
app     step
-----     ----
SAPP1     9320
SAPP1     9332
SAPP1     1208
SAPP3     9320
SAPP3     9332
SAPP3     1208
```
but you are looking for only 3 of these combinations in DECODE it or the expression BOX. (Have 2 copies of 'SAPP1' e list won't do any good, but it does hurt real, either.)
By the way, is "SAPPI" app with the letter 'I' at the end, or "SAPP1", with the number '1' at the end?

Group Query Help
Oracle 10G version | R/2

This is a Customers table and we will have to find they are elgible for product produced B or both or none.

But if you're serviceble by product B, it is certain that you will be good product a. (imagine the product A is greater coverage of Prouct and be produced is the smallest)

What I have done becomes the product of A B and get the remains that are usable for the product and not product B.

< pre >
CREATE TABLE CUST_TEST
(
Number of cust_id,
Column_serviceable_A varchar2 (2),
Column_Serviceable_B varchar2 (2),
Column_Color_A varchar2 (2),
Column_Color_B varchar2 (2),
Area_OO varchar2 (2),
Area_H varchar2 (2),
Varchar2 (10) STATE
);

insert into cust_test (Cust_ID, Column_serviceable_A, Column_Serviceable_B, Column_Color_A, Column_Color_B, Area_OO, Area_H, STATE)
values(1,'Y','Y','G','G','Y','Y','HYD');

insert into cust_test (Cust_ID, Column_serviceable_A, Column_Serviceable_B, Column_Color_A, Column_Color_B, Area_OO, Area_H, STATE)
values(2,'Y','Y','G','G','Y','Y','HYD');

insert into cust_test (Cust_ID, Column_serviceable_A, Column_Serviceable_B, Column_Color_A, Column_Color_B, Area_OO, Area_H, STATE)
values(3,'Y',,'G',,'Y','Y','HYD');

insert into cust_test (Cust_ID, Column_serviceable_A, Column_Serviceable_B, Column_Color_A, Column_Color_B, Area_OO, Area_H, STATE)
values(4,'Y',,'R',,'Y','Y','BANG');

insert into cust_test (Cust_ID, Column_serviceable_A, Column_Serviceable_B, Column_Color_A, Column_Color_B, Area_OO, Area_H, STATE)

values(7,'Y',,'G',,'Y','Y','CHEN');

insert into cust_test (Cust_ID, Column_serviceable_A, Column_Serviceable_B, Column_Color_A, Column_Color_B, Area_OO, Area_H, STATE)

< pre >
Select

(
Select sum (case when area_oo = 'Y' or area_h = 'Y' then 1 else 0 end) of CUST_TEST one
where column_serviceable_A = 'Y '.
and Column_Color_A ('g', 'A')
and status = 'HYD.
)
-

where Column_Serviceable_B = 'Y '.
and Column_Color_B ('g', 'A')
and status = 'HYD.
)
)
Double;
< / pre >

But I need this 15 times as there are 15 States, I want to do in a single request via the Group of. CUST_TESTis also a view and each query takes once NGOs as customers there 15 million.

Please let me know if you need more information.

Desirable output;

COUNT (*) STATE
HYD 1
BANG null
CHEN 2

Thank you and best regards,

Hello

Thanks for posting the sample data in a useful form. That really helps.

So you want a query that produces a line of output for each value in the column state.
That's exactly what "State GROUP BY" don't:
```
SELECT       state
,       COUNT ( CASE
                  WHEN  column_serviceable_a  = 'Y'
                AND   column_color_a         IN ('G', 'A')
                THEN  1
              END
            )
     - COUNT ( CASE
                  WHEN  column_serviceable_b  = 'Y'
                AND   column_color_b         IN ('G', 'A')
                THEN  1
              END
            )     AS cnt
FROM       cust_test
WHERE       area_oo     = 'Y'
AND       area_h     = 'Y'
GROUP BY  state
ORDER BY  state
;
```
In fact, this becomes 0 as the county when no line meets the criteria of "has".
If you prefer that NULL, as you posted, then replace the first indictment by AMOUNT:
```
SELECT       state
,       SUM   ( CASE
                  WHEN  column_serviceable_a  = 'Y'
                AND   column_color_a         IN ('G', 'A')
                THEN  1
              END
            )
     - COUNT ( CASE
                  WHEN  column_serviceable_b  = 'Y'
                AND   column_color_b         IN ('G', 'A')
                THEN  1
              END
            )     AS cnt
FROM       cust_test
WHERE       area_oo     = 'Y'
AND       area_h     = 'Y'
GROUP BY  state
ORDER BY  state
;
```
Output:
```
STATE             CNT
---------- ----------
BANG
CHEN                2
HYD                 1
```
Note that we do not need duplicate in this problem. Whenever you are tempted to use double, ask yourself why. See if the information you want to be taken from another table that you use when even.

This should be much faster than the original request. Instead of making 2 passes through the table for each status value (2 * 15 = 30 past total), just make a pass through the table.

Simplified 2nd query (for number of NULL).

	SELECT	t.user_id, t.user_date, t.amount
	,	SUM (t.amount) OVER (PARTITION BY t.user_id

	) AS the amount
	Of	t-test
