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?
This is what I've been trying to do.
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.
The query below returns 101 rows. If I replace the column list with an asterik the query returns 892 rows. I do not understand why.
--select *
select Ref_Consultant_CD
,Resident_CD
,ID
,Ref_Facility_CD

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 have an urgent request which is pending with the following problem.
Problem :
I have a table which contains data of various datatypes like alphanumeric,varchar and number.
Now my query is " how to sort the data of the table using alphanumeric field"
How to select the data in a required(MyRequirement) sort order.

12.4PI1
12.4

Means it has to sort the data order by lefthand side of PI and also righthand side of PI.
Pls check the attachment if you are not getting the above data in correct order.
Is there a function or a process to generate and maintain an alphanumeric sequence?
I need to be able to sequentially generate both a 3 and 5 byte case sensitive alphanumeric primary key that uses A-Za-z0-9 characters intermittently of which the 5 byte MAY be a subset of the 3 byte. e.g. the key can be 00000 or a3BD7.
so I need to be able to generate a new 5 char using 3 char base and if that value is not available, generate a unique 5 char value and allocate the substr(1,3) of that value backwards.
Ex1: unique customer location comes in - not a preexisting customer name (same name,different location address doesn't exist) --> select nextval.[5char] into v_long_c to insert into customer_loc table, and substr (v_long_c, 1, 3) for customer name table.
EX 2: unique customer location comes in. customer name exists in customer table with 3char val A39, but that location doesn't exist in customer_location table (5chars are location specific).
I need to take the A39 and generate new 5char for that unique location using that prefix (A39) if possible.
However, a number of a39-- already exist, though not all assigned to the same customer name (we're trying to keep them grouped together but that might not be logically feasible)
How do I select next a39||[2char] for that unique location - and if that value is not available (all 62*62 possibilities have been used for A39--), select nextval.[5charseq] into long_key.
I suspect someone out there knows the functions I can use to create this or has written a package to do just this; I suspect with enough time I could do it, but I don't currently have the time or knowledge to develop it within these deadlines. I thought it would be easier.
My short-sighted solution was to create a static table of all iterations of A-z0-9 5 char values, select one, mark it used and move on. Unfortunately 62^5 is a substantial number (913+million records) and that table took a LOT of space, causing my development server to groan and crack miserably. indexing on it takes a lot of space too (and trying to build multiple indexes exceeded database size). But without an index on the 3char field, selecting an available 5 code from it based on the customer_3char prefix took five minutes - much longer than the fraction of a second I need.
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.
the question is: display locations of the highest 10 costs. if the cost of 11th row is the same as 11th, then display 11 rows.
Consider the following tables
MANAGERID
101
102
103
104
MANAGERID EMPID
101 ----------------24
101-----------------25
101 ----------------26
104 --------------- 27
write sql query to get the following output without using minus,union,intersect.
MANAGERID EMPID
101 ---------------------------------- 24

101 -----------------------------------26
102 -----------------------------------N/A

I am trying to sort columns base on cluster and alpha numeric field.

How can I find the last numeric value in the alphanumeric string?
Example:
LS14160220SPAD show me 0
MN23160224N show me 4
SP34524442 show me 2
To built the Pl/SQL function or SQL query to validate the given string for alphanumeric character.
I would pass the string of size 10 character, we need to validate first 5 character as alphabet, next 4 character as numeric and last 1 character as alphabet.
I will pass the each row value to the function, it need to return "T" or "F" based on the condition,first 5 character as alphabet, next 4 character as numeric and last 1 character as alphabet.
Here is the DML and DDL.
[code]
create table abc ( classid varchar(10));
insert into abc values ("abcde1234f");
insert into abc values ("abcde12345");
insert into abc values ("ab1de1234f");
insert into abc values ("abcde1234f");
insert into abc values ("abcd21234f");
[code]
Output:
Input : abcde1234f Output : T
Input : abcde12345 Output : F
Input : ab1de1234f Output : F
Input : abcde1234f Output : T
Input : abcd21234f Output : F
I'm a newbie to PL/SQL. I had a quick query about trapping exceptions.
I have a sample table called my_emp, which contains last name, salary, etc. I have written the following code that takes in an employee salary and if the salary exists it displays the last name and corresponding salary. If two or more rows are returned, the exception handles it. Likewise if there are no records with that salary, the exception takes care of it.
I was trying to input an alphanumeric input, such as 1bbb as the salary and of course ORA-06502 error pops up in the sql command line. I now want to trap this using an exception but whatever I try I still get the ORA-06502 in the calling environment rather than getting the 'Not a number' or 'Some other error occured' message. why the WHEN VALUE_ERROR or the WHEN OTHERS exceptions are not trapping the error?
DECLARE
v_sal NUMBER (12) := '&Enter_salary';
v_last_name VARCHAR2(10);
BEGIN
SELECT last_name

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(*)?
