I have seen lots of examples of using PIVOT to return an sql query where the rows have been converted to columns. All the examples I can find require you to have two columns with multiple rows, and also require you to know the data which is in one of columns to make titles for the new columns.
I need something a little different...I have a query using UNION which goes something along the lines of...
SELECT [get data from one place] UNION SELECT [get data from another place] UNION SELECT [get data from another place]
this returns the following... a_val ----- 100 200 300
query to return something like this... a_val1 a_val2 a_val3 ------ ------ ------ 100 200 300
The names of the columns don't really matter. And I dont want to create a new table in the database just for the result.
I have inherited a query that union alls 2 select statements, I added a further field to one of the select statements ( a date field). However I need to add another dummy field to the 2nd select statement so the union query marries up I have tried to do this by simply adding a
select 'date_on' to add a field called date on populated by 'date_on' (the name of the column in the first query)
however when I run the union query i get the error Ora-01790 expression must have same datatype as corresponding expression.
I have a dynamic query stored in a function that returns a customized SQL statement depending on the environment it is running in. I would like to create a Materialized View that uses this dynamic query.
I have data in a table and another in XML file,I used SQL query to retrive the data placed on the table, and link this query with XML query that retrieves the data stored in the xml file. The data stored in the table and xml file sharing a key field, but the xml contents are less than what in the table.I want to show only the data shared between the two queries, how can I do that?
e.g.:
Table emp:
e_id | e_name | e_sal 023 | John | 6000 143 | Tom | 9000 876 | Chi | 4000 987 | Alen | 7800
I have the following four tables with the following structures Table A
ColA1 ColA2 ColA3 ColA4 ColA5 AA 100 CC DD EE
Table B
ColB1 ColB2 ColB3 ColB4 ColB5 AA 100 40452 A9 CDE
when these two tables were joined like the following:
Select colA1,ColA2, ColA3, ColA4, ColB3,ColB4, ColB5 from table A Left outer join (select ColB3, ColB4, ColB5 from table B where colB3 = (select max(colB3) from table B ) on (colA1 = colB1 and ColA2 = col B2)
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.
Is there a technique to getting a Top-N query to work as a sub-select in a larger query -or- is there another way to generate Top-N like results that works as a sub-select?
Background:
We have a large query that is being used to build an export from a legacy HR system to a new one. Amount the data needed in the export is the employees primary phone number.
The legacy HR system allows multiple phone numbers to be stored in a simple table structure:
SELECT emp_id, phone_type, phone_number FROM employee_phones
The new HR system does allow for multiple phone numbers, however they need a primary phone number identified and stored with the employee master information. (Subsequent phone numbers get stored in alternate table.)
From a business perspective, we have decided that if they have a HOME phone in the legacy system that should be the primary in the new system, if no HOME phone, then WORK, if no WORK then CELL.
That can be represented as:
SELECT * FROM employee_people_phones WHERE emp_id = '46021' ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')
SELECT * FROM (SELECT * FROM employee_people_phones WHERE emp_id = '46021' ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')) results WHERE ROWNUM = 1
SELECT phone_number FROM (SELECT phone_number FROM employee_people_phones WHERE emp_id = '46021' ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')) results WHERE ROWNUM = 1
phone_number ------------------- 1111111111
However, when the Top-N query is added as a sub-select in a larger query using the employee id from the larger query (WHERE emp_id = export.emp_id), it fails saying that �export.emp_id� is not a valid id.
(SELECT phone_number FROM (SELECT phone_number FROM employee_people_phones WHERE emp_id = export.emp_id ORDER BY decode(phone_type, 'HOME', 'a', 'WORK', 'b', 'CELL', 'c', 'z')) results WHERE ROWNUM = 1)
1.Any way around this? Is it possible to put a Top-N (with a WHERE clause using data from the main query) in a sub-select?
2.Any alternatives (other than Top-N) to delivering a ROWNUM=1 result with a �custom� ORDER BY statement?
Other Notes: Yes, we know we could do two queries in the data conversion first deliver the bulk data to the target table, and then update with the phone numbers. However, for multiple reasons, that is less than desirable.
I am having a Select query(below Query1) and I want to use one column(sum(col4)) from this Select query to be displayed in another Select query(Query 2). how to display this.
Query 1 :- select a.col1,a.col2,b.col3,sum(b.col4) from tab a, tab b where a.key1=b.key1 and a.key2=b.key2 group by a.col1,a.col2,b.col3
Query 2 :- select a.col1,a.col2,b.col3,sum(b.col6) from tab a, tab b where a.key1=b.key1 and a.key2=b.key2 group by a.col1,a.col2,b.col3,b.col5
I am facing problem with a select query in oracle 10g database from vb.net.It was working for oracle 9. The select statement I have written is as follows
I have one table in database that contains 3 foreign keys to another tables(this three tables name are: manager,worker and employee). in each row only one foreign key is filled.I need to write one query that with attention which column of fk is filled in where clause specified condition is performed. I write simple query in jpa but doesn't work properly
select b from allEmployees b where b.manager.name= :name OR b.worker.name = :name OR b.employee.name= :name
I am looking to get the maximum value for every 24 hour period for a month. So for example my date range can be defined by...
select to_date('&date','mm yyyy')-1 + level as DateRange from dual connect by level <= '&days'
...where I can provide the first date of the month and number of days in the month or a lesser value if less time is required. So, the results of the above query plus 24 for the range. I thought a some Googling would provide me what I needed, but my search came up empty.
I was hoping to do something like this...
select utctime, max(value) from table where utctime between.
SELECT so.* FROM shipping_order so WHERE (so.submitter = 20) OR (so.requestor_id IN (SELECT poc.objid FROM point_of_contact poc WHERE poc.ain = 20)) OR so.objid IN (SELECT ats.shipping_order_id FROM ac_to_so ats WHERE (ats.access_control_id IN (selectac. objid FROM access_control ac WHERE ac.ain = 20 OR ac.group IN ('buyers', 'managers'))))
rewrite this query to use joins. That would greatly simplify my sql query building code. The ids, objids, submitter, ain are numeric and group is a varchar.
"Determine what departments are in each of the 4 regions. That is, what are the names of the departments that reside in each of the regions." So basically it wants me to list the departments in each region.
This is what the tables look like that it could possibly be drawn from...
I can not use any inbulit function of oracle like "SYS_CONNECT_BY_PATH", "LIST_AGGR" or any other function , even can not use any user defined function.Need to write only SQL to get this result.
I have EMPLOYEE table that have 3 records with EMP_ID 1, 2, 3. Now I want to run below query
select emp_id from employee where emp_id in (1, 2, 3, 4, 5);
It will return only 3 records but i want those records also which is not available in employee table. Is this possible without using another table or creating another table. Actually I don't have enough privileges to create table.
& want output like below
EMP_ID 1 2 3 4 Not Found 5 Not Found
Here emp_id 4, 5 is not available in employee table, but query should return those value also with comments like "Not Found"
how to do a conditional range in a query. For example, I have two tables:
table A: a1 char(1) a2 char(1)
table B: b1 char(1) b2 int
In my query I want to range on a different value in the b2 field depending on what is in the fields in the A table. For example, if the a1 field is Y, I want to look up the record in B with a b2=20. If a2 is Y, I want to look up b2=5. Otherwise I want to look up b2=1. I attempted the following:
select b1 from b, a where b2=(if a1='Y' then 20; elsif a2='Y' then 5; else 1)
test_1 and test_2 are two tables , and in test_1, "score" and "matchno:" are columns and in test_2, "days" is column. in score values are 0 to 1000 and in days values are 0-100
