My goal is to have a de-normalized summary table in which total communication volume for each distinct channel is displayed per customer.Briefly, I would like to reach the following output
When I run the sql below I am not able to de-normalize by customer id; counts are accurate.
SELECT distinct cil.customer_id,
(CASE channel WHEN 'SMS'
THEN (SELECT COUNT (channel) FROM customer_interaction_log cil1
where cil1.channel='SMS' and cil1.customer_id=cil.customer_id) END) SMS_COUNT,
(CASE channel WHEN 'Email'
THEN (SELECT COUNT (channel) FROM customer_interaction_log cil2
where cil2.channel='Email' and cil2.customer_id=cil.customer_id) END) EMAIL_COUNT
FROM customer_interaction_log cil;
i work on oracle 8i with around 950 tables in my database. when i export or import it gives me the no of rows exported / imported from each table. is it possible to take a print out of the no of rows in each table through a single query .
select count(*) from each table takes a long time , since there are 950 tables.
I have a select statement that selects all columns from the join of 3 oracle views. I would like to change it to select only the distinct rows, not sure how to code this. Here is my sql statement:
select * from myschema.view_1 acct Left JOIN myschema.view_2 freq
Productcode Productname Quantity AF Ade Fgh 100 LO Ldo Ope 50 SK Ske Kro 47 ....
There may be any number of records in the table. Now I need to print distinct products in different columns such as.
AF LO SK 100 50 47
There may be any number of products...I need to print all those products as different columns as shown above. How to write the Stored procedure for this?
I had to create a new column in a particular table now i want to insert the values in that column though the other columns are already populated I entered the command (insert into Product(STANDARD_PRICE) values(895.99) when i hit return it says cannot enter null value into (SYSTEM .PRODUCT. PRODUCT_ID) product_id is the PK which is the first column STANDARD_PRICE is the last column in my table...how do i enter the values into that column without receiving this error or having to effect the other columns?
select distinct c.process_id a.role_id,a.email_address,c.process_name from role a, notification_role b, process c where a.role_id=b.role_id and b.process_id = c.process_id
create table eresults (student_name varchar2(20), section_name varchar2(4), exam_id NUMBER (4)) marks NUMBER (3))
[code]....
My requirement is that I need another column named "top scored" which will show how many times each student took highest marks for his Section in each exam_id"
For example in above data the following students "Top scored" for thier respective section in each exam_id:
STUDENT_NAME SECTION EXAM_ID DOLLY A 1 RIZWAN B 1 PAUL C 2 ZAKIR D 2
[code]....
So, based on above my requirement is as below
STUDENT_N SECTION_NAME COUNT(EXAM_ID) SUM(MARKS) MAX(MARKS) top_scored ALEENA C 2 147 91 0 ASIM D 2 68 45 1 ASLAM B 2 70 56 0 ATIF D 2 2 2 0 AYSHA B 2 114 78 0
Now i would like to count from table 1 all p_id with birthday is the same as a s_id.Currently i am doing this:
select s_id, count(tbl1.pid) inner join table 3 using (lid) inner join table 1 using (lid) Where to_char(tbl1.birth_date,'DD') = to_char(tbl2.birth_date,'DD') AND to_char(tbl1.birth_date,'MM') = to_char(tbl2.birth_date,'MM')
when i check it using data, i get a target_id whose birth_day is same as TWO people in tbl1 yet according to that query i am only getting ONE person! rest of the results from that query look fine!
Note: Each player can appear for more than one team in different matches. For exmaple, John appeared for Team A in matchid = 1 and then in matchid = 2 he appeared for team B. So same could be for other players
Requirment: I want for each player, the sum of total number of matches and points (which is easy using SUM) but along with total number of different teammates he played with in all the matches he appeared [for his team(s)] and also the total number opposition players and lastly the total number of different players he played with in all the matches he appeared in.
Just to clarify some terms, incase any doubt:
Here teammates = all players who appeared (for_team) in a match from the same team for whom the respective player also appeared in the same match.
opposition players = all players who appeared for VS_team played by each player.
total different players = all unique players who appeared for for_team or vs_team in the matches in which each player appeared.
Here is my desired outout: Player total Matches Sum(points) Different teammates Different opposition players total different players player played with player played with player played with John 3 4 5 5 10 Fulton 2 11 3 4 6 Sarah 1 9 2 3 5

I want one simple query and shortest query to achieve about output since in my actual table data is huge.
I would like to write a query on USER_SOURCE that can display the number of code lines for each procedure/function in a package. Is it possible to write such a query? Maybe by using analytical functions?
for example in the following example i would like to count the lines between
"PROCEDURE proc1 IS" and "END proc1;" and between "PROCEDURE proc2 IS" and "END proc2;" SQL> select text from user_source where name='PKG_TEST' and type='PACKAGE BODY';
TEXT -------------------------------------------------- PACKAGE BODY PKG_TEST IS /************************************************* ****/ PROCEDURE proc1 IS BEGIN update t1 set EDITION_NAME = 'AAAAAAA'; commit; END proc1; [code]....
How the people in production counts the exact position of the data in fixed format of Sql*loader? Isn't it critical especially in a critical and having many column to be inserted.
primary key constraint on transaction_dtl_bk is affecting the insertion of next correct rows.

We have to load 10 million rows in a table from another table based on the multiple joins. How much tablespace size we allocate to the table and for performance point of view how much should be the SGA size.
I am running a GROUP BY query on a few columns of enumerated data like:
select count(*), Condition, Size group by Condition, Size;
COUNT(*) CONDITION SIZE -------- ---------- -------- 3 MINT L 2 FAIR L 4 FAIR M 1 MINT S
Well, let's say I also have a timestamp field in the database. I cannot run a group by with that involved because the time is recorded to the milisec and is unique for every record. Instead, I want to include this in my group by function based on whether or not it is NULL.
For example:
COUNT(*) CONDITION SIZE SOLDDATE -------- ---------- -------- ---------- 3 MINT L ISNULL 2 FAIR L NOTNULL 2 FAIR M NOTNULL 2 FAIR M ISNULL 1 MINT S ISNULL
I want to purge a table which is having more then 98M rows...here are the details...
Purge Process I followed --------------------------------------------- Step 1. Created backup table from Main table with required data only create table abc_98M_purge as select * from abc_98M where trunc(tran_date)>='01-jul-2011' -> table created with 5325411 rows
Step 2. truncate table abc_98M
Step 3. inserted all 5325411 rows back to abc_98M from abc_98M_purge using below procedure
DECLARE TYPE ARRROWID IS TABLE OF ROWID INDEX BY BINARY_INTEGER; tbrows ARRROWID; row PLS_INTEGER; cursor cur_insert is select rowid from abc_98M_purge order by rowid; BEGIN open cur_insert; loop [code]....
2)select client_id, count(*) from TCLIENT_NOTIFICATION_PACK where client_id=1620560178 group by client_id having count(*) > 40 order by 2 desc client_id count(*) ----------- --------- 16205601785128
3) select client_id,clnt_notification_pack_tid -- bulk collect into v_client_id,v_notif_tid from (select clnt_notification_pack_tid, client_id, clnt_notification_pack_typ_tid, crte_dt,
[code]....
4) Iam using the below proc to delete the rows from table, except the 4 rows returned above
declare v_clnt_notification_pack_tid TCLIENT_NOTIFICATION_PACK.CLNT_NOTIFICATION_PACK_TID%type; tYPE t_client_id is table of TCLIENT_NOTIFICATION_PACK.client_id%type; tYPE t_notif_tid is table of TCLIENT_NOTIFICATION_PACK.clnt_notification_pack_tid%type; v_client_id t_client_id; v_notif_tid t_notif_tid;
[code]....
5) After running this procedure, i shud see 5124 records, but i see zero records.
