SELECT COUNT(c.country_id)

departments d
[Code]....
I really dont know when and where to use the group by statement from the query above when I added C.country name before the word from I'm always getting this error "ORA-00979: not a GROUP BY expression"
I'm trying to group sets of data based on time separations between records and then count how many records are in each group.
In the example below, I want to return the count for each group of data, so Group 1=5, Group 2=5 and Group 3=5
SELECT AREA_ID AS "AREA ID",
LOC_ID AS "LOCATION ID",
TEST_DATE AS "DATE",
TEST_TIME AS "TIME"
FROM MON_TEST_MASTER
WHERE AREA_ID =89
AND LOC_ID ='3015'
AND TEST_DATE ='10/19/1994';
[code]....
Group 1 = 8:00:22 to 8:41:22
Group 2 = 11:35:47 to 11:35:47
Group 3 = 15:13:46 to 15:13:46
Keep in mind the times will always change, and sometime go over the one hour mark, but no group will have more then a one hour separation between records.
I read that rownum is applied after the selection is made and before "order by". So, in order to get the sum of salaries for all employees in all departments with a row number starting from 1, i wrote :
select ROWNUM,department_id,sum(salary) from employees group by department_id
If i remove rownum, it gives the correct output. Why can't rownum be used here ?
Refer to the txt file to create table and insert data.
I executed the following query-
SELECT priority, detail, COUNT(1) FROM TEST GROUP BY priority, detail
and got the following result-
PRIORITYDETAIL COUNT(1)
StandardPatch 27
StandardInitial TSS 1
StandardInitial development 10
StandardProduction deployment5
High PriorPatch 1
Now I want that Initial TSS and Initial development should be combined as Initial together and I should get the result as follows:
PRIORITYDETAIL COUNT(1)
StandardPatch 27
StandardInitial 11
StandardProduction deployment5
High PriorPatch 1

I am using JDBC to run a few queries from my Java program (multi-threaded one).I am facing an issue where a select statement is blocking a delete statement. From the java code point of view, there are 2 different threads accessing the same tables (whith different DB connection objects).
When the block occurs (which i was able to find out from the java thread dump that there is a lock on oracle), the below is the output:
SQL> SELECT TO_CHAR(sysdate, 'DD-MON-YYYY HH24:MI:SS')
2 || ' User '||s1.username || '@' || s1.machine
3 || ' ( SID= ' || s1.sid || ' ) with the statement: ' || sqlt2.sql_text
||' is blocking the SQL statement on '|| s2.username || '@'
4 5 || s2.machine || ' ( SID=' || s2.sid || ' ) blocked SQL -> '
6 ||sqlt1.sql_text AS blocking_status FROM v$lock l1, v$session s1, v$lock l2 ,
7 v$session s2,v$sql sqlt1, v$sql sqlt2
8 WHERE s1.sid =l1.sid
9 AND s2.sid =l2.sid AND sqlt1.sql_id= s2.sql_id
AND sqlt2.sql_id= s1.prev_sql_id AND l1.BLOCK =1
10 AND l2.request > 0 AND l1.id1 = l2.id1 AND l2.id2 = l2.id2;
[code]...
From the above it can be seen that a select statement is blocking a delete. Unless the select is select for Update, it should not block other statements is not it ?
Is there any way to add one disk group space to another disk group. Because One of my disk group is full i want to add space in to that group.

Basically (as you can see) I need to get a normal count for each group but also for each group take a percentage of the total count (so all groups pct adds up to 100 (oh yeah, don't test for zero below, but just a test... )

If i inserted the values in table it gets inserting very few rows only.I dont know y it is?
View 15 Replies View RelatedCREATE TABLE TEMP_GP_SEQ
(
COL1 NUMBER,
COL2 NUMBER,
COL3 NUMBER,
COL4 NUMBER,
COL5 NUMBER,
COL6 NUMBER,
COL7 CHAR (25)
);
[Code]...
I need to update the TEMP_GP_SEQ table and on the COLUMN COL7 based on the grouping range mentioned above using the sequence created. But the sequence should not be incremented for each and every record, it should be incremented only for change of groups. For example
SELECT *
FROM TEMP_GP_SEQ;
COL1 COL2 COL3 COL4 COL5 COL6 COL7
110100
110101
12101001
[Code]...
After update it should look like
SELECT *
FROM TEMP_GP_SEQ;
COL1 COL2 COL3 COL4 COL5 COL6 COL7
110100
110101
12101001M2
[Code]...
Actually the group by fetched two rows with a total record count of 4 (2 records in both the rows). SO the COL7 is updated for these four rows with M as a prefixed word and the number followed after M is from the sequence. Here the number is changing (sequence is incrementing) only when there is a change in grouping criteria and it remains the same throughout a group.
how to logically connect two tables. Here is an example of what I'm trying to do:
HOSTS TABLE CPU TABLE
----------- ---------
ID HOST ID CPU
01 host1 01 proc01
02 host2 01 proc02
03 host3 02 proc01
02 proc02
02 proc03
02 proc04
03 proc01
Based on the above, I can see that 'host1' has 2 CPUs, 'host2' has 4 CPUs, and 'host3' has 1 CPU. What I'd like to do is create a query that would output:
HOST CPU
----------
host1 2
host2 4
host3 1
I'm looping through the hosts and passing the them into another query as bind variables. That's slow and cannot be the best way to do this. I'm aware that I need to using a GROUP BY HAVING COUNT, but that doesn't seem to be working. It tends to return the total count of all CPUs rather than CPUs per host.

My requirement is Data from a TableA has to be provided as an overall view

Where "Expand", "Report", "Populate" are provided as Hard coded values in query.

Above query works fine, where single ID is present

ACCNT Y Y Y
PROD Y Y Y
ADDR Y N N
But when more than one ID is present the entire thing collapses

Why wouldn't it use the index in the group by? If I write a loop to query for different partnerid (there are only three), the whole things takes less than a second.
