In sql plus How do I get the number of distinct rows of a certain value?
for example
select group_number from records group by group_number
How would I query for the total number of group_numbers in this query?
I have a column COL1 in table TAB1 which is varchar2. I want select only rows which has number and not alphanumeric value? I don't want to use regexp for this since

I have the following table:
FOOTBALL PLAYERS < ID, NAME, ATTRIBUTE>
100-JIM-TALL
101-BOB-STRONG
102-MARK-SMART
...etc
I want to form a query that regardless of the total returned records, I will be able to specify how many of each "kind" of players I want returned. There are several good reasons that it has to be one query and not many.
I am facing a problem in bulk insert using SELECT statement.My sql statement is like below.
strQuery :='INSERT INTO TAB3
(SELECT t1.c1,t2.c2
FROM TAB1 t1, TAB2 t2
WHERE t1.c1 = t2.c1
AND t1.c3 between 10 and 15 AND)' ....... some other conditions.
EXECUTE IMMEDIATE strQuery...These SQL statements are inside a procedure. And this procedure is called from C#.The number of rows returned by the "SELECT" query is 70.
On the very first time call of this procedure, the number rows inserted using strQuery is 70. But in the next time call (in the same transaction) of the procedure, the number rows inserted is only 50.And further if we are repeating calling this procedure, it will insert sometimes 70 or 50 etc. It is showing some inconsistency.On my initial analysis it is found that, the default optimizer is "ALL_ROWS". When i changed the optimizer mode to "rule", this issue is not coming.I am using Oracle 10g R2 version.
I am importing some data from Oracle into another database on a regular basis. It works fine for most of the queries but couple of queries don't work sometimes (random). I don't get any errors or any data.
We switched on the Oracle auditing to find out the queries being sent to oracle db. We can see all the queries in the Audit log. Is it possible to configure Auditing to get the "Number of Rows" returned by Select statements so that we can be sure that some data was returned.
I am working on a script in which I want to retrieve multiple rows but I get error ORA-1422.I tried solving it using the following script , but it still gives error.
CREATE OR REPLACE PROCEDURE proc_query
DECLARE
TYPE all_dest IS TABLE OF NUMBER;
destIds all_dest;
BEGIN
SELECT dest_id from sb_packet WHERE src_id = 32;
RETURNING dest_id bulk collect into destIds;
END;
I understand what the message "subquery returning multiple rows" means but I have a case where I'm not 100% sure why it's happening to my update query (which in turn probably means I don't fully understand what's going on behind the scenes)
Here is my query:
Update A set (A.id, A.alt_name, A.min_rank)=
(SELECT B.id,
B.fullname,
MIN(B.nm_rankval)
FROM B,
A
WHERE A.id = B.id
AND A.name <> B.fullname
AND B.nametyp = 'ON'
GROUP BY B.id,
B.fullname)
;
The subquery returns 6 rows but they are all unique in terms of the id, name, rankval, etc...I naturally thought that the update statement wouldn't have a problem with this since the subquery is returning rows that are not duplicates and match one for one between table A and B. I used the group by to ensure I return unique values from table B (which does have duplicate id values)
Each of those 6 rows from the subquery of table B can be matched 1-1 with table A...so what am I missing.
The following code is indicative of what I'd like to do (as in not correct at all ). Would there be a more immediate way to accomplish this other than executing a SELECT statement after the UPDATE?
-- Incorrect indicative example 1.
DECLARE
v_cur SYS_REFCURSOR;
BEGIN
UPDATE table1(f1, f2)
SET ('v1', 'v2')
WHERE f3 = 'v3'
RETURNING <updated_rows> INTO v_cur
END;
-- Incorrect indicative example 2.
DECLARE
v_cur SYS_REFCURSOR;
BEGIN
OPEN v_cur FOR
UPDATE table1(f1, f2)
SET ('v1', 'v2')
WHERE f3 = 'v3'
END;
This is a surprisingly common one I've found on the web...even on devshed forum
I am updating one table from another (Updating Table A from Table B):
Table A
ID, Value
-- -----
1 A
1 A
2 B
Table B
ID, Value
-- -----
1 Animal
2 Box
Table A (modified)
ID, Value, Name
1 A Animal
1 A Animal
2 B Box
No I need to update a new column in Table A with the value in Table B.Value where the ID's from both tables match. Problem is: When I do this I get multiple rows and hence Oracle won't let me update this column. Now, I keep reading that for these types of updates, there has to be a one-to-one relationship...
Is this true...is there anyway of telling Oracle to update wherever it finds that ID, regardless of how many duplicate ID's there are?
This is quite a frustrating problem and most of the sites that I've looked for solutions try get the query one-to-one...problem is...with my table sets it's impossible to do that - I need to update wherever the id's match (even if it return multiple rows).
I'm trying to write a query that counts how many sessions are active during a 1 second time interval, then returns the maximum number of sessions active during any time interval, and all the time intervals that hit that max.
Here's a sample of the inner query results:
"INTERVAL_VALUE""SESSIONS"
"13:14:47" 13
"13:14:52" 13
"13:14:54" 13
"13:19:05" 4
"13:19:28" 4
[code]....
The max(sessions) is 13, so what I want the final output to be is:
"INTERVAL_VALUE""SESSIONS"
"13:14:47" 13
"13:14:52" 13
"13:14:54" 13

I am trying to find records in table A that don't have any corresponding records in table B
select a.ID,a.templatenames from cbe a where not exists (select 1 from cbe_child b where a.ID=b.cbe_id)
Both tables have about 100 mil rows. And there is no Parent/Child relationship here, A.ID is a PK column.how can i write this select to perform better.
how can I select whole table in parts of 100 rows?
If I have primary key I can:
CODEstart=0;
end=100;
select * from table where ID>=start_point and ID<end;
start=end;
end=end+100;
and repeat:
CODEselect * from table where ID>=start_point and ID<end;
How can I do it without primary key? Is there another posibility to getting 100 number of rows? Maybe using rowid?
i have a table displaying location, cost, inner_num and rownum ordered by the descending order of the cost.

67 1
67 2
67 3
67 4
67 5
13 1
13 2
I would like to retrieve the rows for every different ID with its max value. For one ID that would be:
select * from TABLE where seq in(
select max(seq) from TABLE where id=24)
How can i do this for all the rows??
is there a way to find out how many rows a View has? Something similar to NUM_ROWS with regular tables perhaps? Or do I have to use Count(*)?

This is not correct. Due to the end_date this row should not be part of the results.
