I have a table which stores Employees and their Phone numbers. Each employee can have multiple numbers e.g.
Employee, Number
Adam, 123
Adam, 456
John, 123
John, 456
I am trying to write a select statement that will split the rows into columns and group by each employee e.g.
Employee, Number1, Number 2
Adam, 123, 456
John, 123, 456
I have data like :
ID NAME1 NAME2 NAME3
JJ AD MED
VI TIBO PH TIBO
I want output like
ID NAME
JJ AD
JJ MED
VI TIBO
VI PH
VI TIBO
Below is the query that I have:
Quote:
select a.contact, b.db_name
from MOM.db_contacts@DB_LINK a, MOM.databases@DB_LINK b,
where a.DB_ID=b.DB_ID
and b.DB_name=(SELECT unique substr(upper(t.target_name), 1, instr(t.target_name,'_',1,1)-1)
FROM mgmt_targets t JOIN mgmt_current_severity s
ON s.target_guid = t.target_guid
WHERE t.target_type = 'oracle_database'
and UPPER(t.target_name) like '%11GDB%');
How can I add two more columns into the select statement and the two columns are in the tables that were in the sub query..I would like to have something like this:
Quote:
select a.contact, b.db_name, COLUM1, COLUMN2
from MOM.db_contacts@DB_LINK a, MOM.databases@DB_LINK b, mgmt_targets t, mgmt_current_severity s

and b.DB_name=(SELECT unique substr(upper(t.target_name), 1, instr(t.target_name,'_',1,1)-1)

I am student of Oracle programming(SQL).Has a question on MIN and MAX functions:
- "Write a SELECT statement that returns one row for each customer with four columns--the customer's first and last name, the date of the customer's most recent order, and the date of the customer's oldest order and the difference between the two dates. Sort the result set so the customers who have been ordering with the company the longest appear first. Use most recent order date as a tie-breaker for the sort."
where orders and order_details,customers are 3 different.this is my query ...but its not working.
SELECT DISTINCT customers.customer_first_name||' '||customers.customer_last_name AS Customer_name,MAX(order_date) AS "Most recent order", MIN(order_date) AS "Oldest order"
FROM customers
INNER JOIN orders
ON customers.customer_id=orders.customer_id
LEFT JOIN order_details
ON orders.order_id=order_details.order_id
LEFT JOIN items
ON order_details.item_id=items.item_id
ORDER BY Customer_name
If i inserted the values in table it gets inserting very few rows only.I dont know y it is?

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.

In this query split is a pipe line function to convert row(rows stored with , delimited) as columns like below
for ex for below query
SELECT * from TABLE(SPLIT('bbb003,bb004'));
out put is
bbb003
bb004
now i have to apply same function on column,column is storing data with ',' separated.and i have tried like but it's throwing missing expression. how i can use this function on entire column from this table.
SELECT * from TABLE(SPLIT(select candidates FROM ibis.cw_uploads_inprogress ));
SELECT 'TEST','F1,F2,F3,F4' from dual
I want to split the rows by comma separated as below
TEST F1
TEST F2
TEST F3

I have a table that has about 20,000 rows.
There is a column called Keyword which has values like below:
File_IDKeyword1SMITH;ALLEN;WARD;JONES; BRADY2S&P500;TOPIX3SMALL;LARGE;MEDIUM
I want to output the data like this: FILE_IDKEYWORD1SMITH1ALLEN1WARD1BRADY2S&P5002TOPIXetc
I'm using this query and it works: SELECT STG.FILE_ID, REGEXP_SUBSTR(STG.KEYWORD,'[^;]+', 1, LEVEL) AS KEYWORD FROM STG_TABLE STGCONNECT BY REGEXP_SUBSTR(STG.KEYWORD,'[^;]+', 1, LEVEL) IS NOT NULL
But its sooooo slow, its unusable. Is there a quicker way to return this output? Other info:KEYWORD is varchar2(4000) but rarely more than 100 bytes are usedOracle 11g2 !
I have a query that produces around 11 fields, and one of which is a multi-delimited field and the other 10 are dimension fields. I would like to split that field into several rows, and have the other 10 fields just repeated for each one. Here is an example of the data in the 11th field :
Column 11
34^56^78,59
There are two delimiters in the field, a carat and a comma. This field is used to reference document numbers that are needed to be sent in. The carat represents the word "Or" and the comma represents the word "And". I would like to have the output of each field to be a repeat of the 10 dimension fields, plus 3 new fields. The first new field would be the document number, the second new field would be the position within the original delimited field(1, 2, 3, etc.) , and the last field would be one of three logic words :First (if it is the first value), Or (if the value followed a carat), And (If the value followed a comma). Example of the output from the above value would be :
Column 11 Column 12 Column 13
34_______ 1_______ First
56_______ 2_______ Or
78_______ 3_______ Or
59_______ 4_______ And
Any thoughts on this? I have found a few solutions online on how to break up the delimited field into rows, but never with multiple delimiters or with extra logic for the added fields.

View 4 Replies View RelatedI 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 ?
Why Blind select is better than Conditional select Statement?

My dilemma is such: let's say that I have 1 teacher in an entity, and this teacher has 3 students in an associative entity. So if you did a select T.teacher, S.student from TEACHER T, STUDENT S, where T.teacher_id = S.teacher_id, you would get 3 rows:
Teacher 1, Student 1
Teacher 1, Student 2
Teacher 1, Student 3
How I would like to display it, is in 1 row:
Teacher 1, student 1/student 2/student 3
