My logic should have the output as follows without 5th column: sourcerowleveldpnqtyremark13Y522Y4This row in main table shouldn't be displayed in the query result as it has
dpn='N'44Y3*3=9In this row qty=9 will bedisplayed.
It will compare the value of level column with its previous row level col,if it is the parent of the current(ex.current is 4 and previous is 3 parent of 4),then it will check the dpn of previous row ,if dpn='N' then qty of parent will be multiplied with qty of current row and displayed under qty column.this row will not be displayed as dpn='N'this row will not be displayed as dpn='N'72Y4*6=24in its previous row level value is same so it will check the previous to previous row where level is 1(parent of current row) and dpn='N' ,then it will multiply the qty of that row with current row and display the value in qty column.this row will not be displayed as dpn='N'94Y2*2=4In this row qty=4 will be displayed.It will compare the value of level column with its previous row level col,if it is the parent of the current(ex.current is 4 and previous is 3 parent of 4),then it will check the dpn of previous row ,if dpn='N' then qty of parent will be multiplied with qty of current row and displayed under qty column.101Y3It will not check for the previous rows as level 1 doesn't have any parent.
We have employee salary table which will have salary of an employee on daily basis (only working days). Below is the table structure:
CODEemp_salary ---------- emp_id NUMBER(15) NOT NULL effective_date DATE NOT NULL salary NUMBER(15) NOT NULL
Primary key - emp_id, effective_date..This table is yearly partitioned...I have to find out how long the salary is not changed for an employee from given date, and last salary. I am using below query to do this:
CODEWITH salary_tab AS (SELECT effective_date, salary, (CASE WHEN (LAG (salary) OVER (PARTITION BY emp_id ORDER BY effective_date ASC) = salary
[code]....
For emp_id 1, if we ran this query for 10/31/2011, then it has to compare the 10/31 salary with 10/29 and do the same until the salary mismatches. In this case, salary salary mismatch occurs on 10/20, so the stale salary period is from 10/31 to 10/21 which is 7 days.Below query will give that result:
CODE WITH salary_tab AS (SELECT effective_date, salary, (CASE WHEN (LAG (salary) OVER (PARTITION BY emp_id ORDER BY effective_date ASC) = salary
I am trying to set the min date if there is no gap between dates.compare previous date2 value with current date1,if they are same then my new date will be min(date1).
How can I compare two rows from the same table and show the field and the difference?
Example:
select ename, job, mgr, hiredate, sal, deptno from EMP t where t.empno = 7782 or t.empno = 7788
ENAME JOB MGR HIREDATE SAL DEPTNO 1 CLARK MANAGER 7839 6/9/1981 2450.00 10 2 SCOTT ANALYST 7566 6/9/1981 3000.00 20
My report comparing fields should be:
FIELD BASE COMPARE DIFFERENCE ENAME CLARK SCOTT -- JOB MANAGER ANALYST -- MGR 7839 7566 -- SAL 2450 3000 550 --(Show difference only for numbers) DEPTNO 10 20 --
We have employee salary table which will have salary of an employee on daily basis (only working days). Below is the table structure:

WITH salary_tab AS (SELECT effective_date, salary, (CASE WHEN (LAG (salary) OVER (PARTITION BY emp_id ORDER BY effective_date ASC) = salary ) THEN 0 ELSE 1 END ) changed_ind FROM emp_salary WHERE emp_id = 12345 [code]....
The cost of this query is 1677 and it is taking around 60 msec to complete. When I run this query for around 2000 employees in a loop it is taking around 3 minutes to complete.
The main bottleneck of this query is in the with clause where I am processing the entire history instead of stopping after first change.
I have got a procedure that successfully creates an oracle external table and populates it with the contents of a file. This works fine until I have a situation where one of the fields is a VARCHAR2(2) and I try to insert say, a 5 character value. When this happens the record in question does not get populated in the external table (and rightly so), but I could do with working out if there is a discrepancy in the number of records in the file and the number of records that actually make it into the table so I could inform the user that there is a problem.
I have attached the code that creates the external table and populates it.
How to get the previous value of row with calling function to add value in SELECT statement for the row value.
Consider the example Table A1 having column a with values 1,NULL,NULL,NULL
SELECT CASE WHEN a IS NULL THEN (prev_row_value+function_return_Value) ELSE a END as A from A1
And my result-set should be like
a ---------------------- 1 1+(Return Value Of Function) Prev_Row_Value+(Return Value Of Function) Prev_Row_Value+(Return Value Of Function) Below is sample code but doesn't fulfill my criteria
I have to generate a report for the audit with in the dates specified(range). I got the set of record for the specified date range by using the following query:
select * from fee_rule_aud where TO_NUMBER(TO_CHAR(TRUNC(audit_date),'YYYYMMDD'))>20090629 and TO_NUMBER(TO_CHAR(TRUNC(audit_date),'YYYYMMDD'))<=20100710 order by fee_rule,audit_date
this query returned some five records, now I have to iterate through this and compare 1st and 2nd row in first iteration (1st row will have the new value and 2nd row will have old vale). If there is any difference then insert into audit_log table which has the following structure:
Fee_rule , column_name, old_value,new_value
This process has to repeat for all the 5 rows like comparing 1st,2nd rows and 2nd,3rd rows and 3rd,4th rows and so on if it has more rows.
I have two tables which have identical schemas, one table (tbl_store) is used to hold the latest version, and the other table (tbl_store_audit) holds previous versions. When the latest record is updated, it is inserted into the tbl_store_audit table as a revision, and the updated details are used as the latest record.
For example: The latest version is held in tbl_store, however the tbl_store_audit may hold 5 records which are the past records used before changes were made - these are seen as revisions.
I want to be able to compare what has changed between each revision in the tbl_store_audit table. For example: Out of the 10 columns, the change between revision 1 and revision 2 was the size from XL to XXL. The change between revision 3 and revision 4 was the size XS to M and price 4.99 to 10.99, and so on.
Eventually i will create an APEX report that will show the user the revision number and what was changed from and to.
I seen in a previous post i need to note my oracle version: Oracle version 10.2.0.4.0
I need to view the rows of the result of a select query in table format in GUI application.I have used XMLELEMENT to somewhat match the scenario to display as ','(comma) separate values as b belwo
I need each different ACC_ID with ACC_AMT in different columns. The table may have other different ACC_ID also, but I will fetch only what I need. What is the best way to do this?
So far I have tried this:
SELECT (CASE WHEN ACC_ID=111 THEN ACC_ID END) AS ACC_ID_1, (CASE WHEN ACC_ID=111 THEN ACC_AMT END) AS ACC_AMT_1, (CASE WHEN ACC_ID=222 THEN ACC_ID END) AS ACC_ID_2, (CASE WHEN ACC_ID=222 THEN ACC_AMT END) AS ACC_AMT_2, (CASE WHEN ACC_ID=333 THEN ACC_ID END) AS ACC_ID_3, (CASE WHEN ACC_ID=333 THEN ACC_AMT END) AS ACC_AMT_3 FROM <TABLE_NAME>
create table FIELDS ( FIELD_NAME VARCHAR2(30) not null, PRG_FIELD NUMBER not null, LENGTH NUMBER );
with
INSERT INTO FIELDS VALUES('FIELD1', 1, 3); INSERT INTO FIELDS VALUES('FIELD2', 2, 3); INSERT INTO FIELDS VALUES('FIELD3', 3, 4); INSERT INTO FIELDS VALUES('FIELD4', 4, 2); INSERT INTO FIELDS VALUES('FIELD5', 5, 1);
I need to insert in a table:
create table STUFF ( FIELD_NAME VARCHAR2(30) not null, FSTART NUMBER not null, LENGTH NUMBER );
And the output I want is:
INSERT INTO STUFF VALUES('FIELD1',0,3); INSERT INTO STUFF VALUES('FIELD2',3,3); INSERT INTO STUFF VALUES('FIELD3',6,4); INSERT INTO STUFF VALUES('FIELD4',10,2); INSERT INTO STUFF VALUES('FIELD5',12,1);
So each field starts where the previous (ordered by PRG_FIELD asc) ends.
I think the query should use both lag and connect by but I haven't had any luck writing it. The problem is that all the examples I've seen around, using connect by prior, utilize 2 fields with different names, es connect by prior emp_id = mgr_id. Instead I should do something like connect by prior prg_field = prg_field-1 but that doesn't seem to work.
PS: I don't necessarily need to do this, I have a guy manually writing the inserts, this is just an exercise I would like to figure out
I have a need to query a real time production database to return a set of results that spans a three day period. When the three days are consecutive it's easy but sometimes there is a 1 or two day gap between the days. For example I'm querying results from a group of people that work between Tuesday and Saturday. On a Wednesday I need t produce a set of results that spans Tuesday of the current week, and Saturday and Friday of the previous week; on Thursday I need to produce a set of results that that spans Wednesday and Tuesday of the current week and Saturday of the previous week.I'm using SQL Developer to execute the code.
I would like to have a query which should fetch previous day records from column which is having timestamp data type.
select mdn from user_table where updatetimestamp > trunc(sysdate) - INTErVAL '24' HOUR;
But this gives output not for previous day, but all records which are 24 hrs less than current day. How to get records for previous day based on column having timestamp data type.
I have a stat table that got info like login_date,user_id etc.For a specific user, i have a requirement based on the no of days difference between the current login date and last login date.
For example, Tom logged in on June 4th 2013. His previous login was May 31. So no_of_days_difference is 5 days.How to programmatically get this for each user inside a pl-sql sub block.
I need to compare columns of two tables in oracle 10g. If columns of both tables match with each other, then i need to create new table dynamically with matched column name and datatype. For example, table1 contains name, ID, Phone_no and address table2 contains name, Id, address, area and pincode. now , i need to create table3 which will contains name, ID,address, Phone_no, area and pincode as columns( I mean matched columns should not be repeated in table3). how to do this..
I want to check whether language is already there in database or not.
i have written the below query
select * from emp where language_known =nesttype('english','hindi');
i am getting the below error
SQL Error: ORA-22901: cannot compare nested table or VARRAY or LOB attributes of an object type 22901. 00000 - "cannot compare nested table or VARRAY or LOB attributes of an object type" *Cause: Comparison of nested table or VARRAY or LOB attributes of an object type was attempted in the absence of a MAP or ORDER method. *Action: define a MAP or ORDER method for the object type.
I have a query that is pulling back more rows when I use the dblink than when I hit the linked database directly.
For example:
select x,y,z from mytable@dblink
returns 788,324 rows
while select x,y,z from mytable
returns 712,102 rows
It's the exact same query, with the only difference being the dblink. It's not pulling the data into a cursor or array, it's a simple, straightforward query on a remote database.
I am trying to import the schema into 11g database, which i took on Oracle 9i database. While import is running, data file is full as auto extension was not enabled.
I got the following error:
. . importing table "WO_GL_ACCOUNT_SUMMARY" IMP-00058: ORACLE error 1653 encountered ORA-01653: unable to extend table PWRPLANT.WO_GL_ACCOUNT_SUMMARY by 1024 in tabl espace PWRPLANT IMP-00018: partial import of previous table completed: 7055845 rows imported.
Then I increased the datafile size and finally Import terminated successfully with warnings. At this point, I want to know whether WO_GL_ACCOUNT_SUMMARY Table was imported with out missing any rows .
I am trying to compare records in a table in both Oracle and MSSQL database against a single standard dataset in my test case. However, I'm getting different results for each when I sort using a "order by".
select COL1 from TABLE1 order by COL1
In MSSQL, I get: COL1 ===== A A. A++ A++.
In ORACLE, I get: COL1 ===== A A++ A++. A.
I mean, oracle result some what makes sense, because "." has bigger ascii value than "+". But is there anyway to make the ORACLE sort order look exactly like MSSQL result?
