I have 8 columns. Some of them might be null.I want to display all 8 columns in my result. Not null columns will be first and null at the end.Here is a sample data :
I need each different ACC_ID with ACC_AMT in different columns. The table may have other different ACC_ID also, but I will fetch only what I need. What is the best way to do this?
So far I have tried this:
SELECT (CASE WHEN ACC_ID=111 THEN ACC_ID END) AS ACC_ID_1, (CASE WHEN ACC_ID=111 THEN ACC_AMT END) AS ACC_AMT_1, (CASE WHEN ACC_ID=222 THEN ACC_ID END) AS ACC_ID_2, (CASE WHEN ACC_ID=222 THEN ACC_AMT END) AS ACC_AMT_2, (CASE WHEN ACC_ID=333 THEN ACC_ID END) AS ACC_ID_3, (CASE WHEN ACC_ID=333 THEN ACC_AMT END) AS ACC_AMT_3 FROM <TABLE_NAME>
I am trying to search a word which starts with 'FRA' in any columns and any tables.
I am unable to find what is generating a join datasets in the webservice from teh database as it is not apparent within the 100 tables.
I ahve looked into
Re: How to search in all rows and all columns? Re: SQL Search Query?
but none of these queries is working out for me as I am a user with no tables on its own but rather a user quering other tables.I think its a tweak on which dat a dictionary I can view
select distinct substr (table_name, 1, 14) "Table", substr (t.column_value.getstringval (), 1, 50) "Column/Value" from all_cons_columns, table (xmlsequence (dbms_xmlgen.getxmltype ('select ' || column_name || ' from ' || table_name || ' where upper(' || column_name || ') like upper(''%' || 'fra' || '%'')' ).extract ('ROWSET/ROW/*') ) ) t order by "Table";
running teh above query got me thsi error:
ORA-19202: Error occurred in XML processing ORA-00942: table or view does not exist ORA-06512: at "SYS.DBMS_XMLGEN", line 288 ORA-06512: at line 1 19202. 00000 - "Error occurred in XML processing%s" *Cause: An error occurred when processing the XML function *Action: Check the given error message and fix the appropriate problem
create type emp_obj_dtl as OBJECT (ename varchar2(50),mgr NUMBER) create type emp_dtl_obj_typ as TABLE of emp_obj_dtl
Using the these object i have created on function as
CREATE OR REPLACE FUNCTION emp_test_func (peno NUMBER) RETURN emp_dtl_obj_typ AS lv_emp_dtl emp_dtl_obj_typ := emp_dtl_obj_typ (); BEGIN SELECT emp_dtl_obj_typ(emp_obj_dtl (ename, mgr)) INTO lv_emp_dtl FROM emp WHERE empno = peno;
RETURN lv_emp_dtl; END;
Now if i am executing query as
SELECT empno, emp_test_func (empno) emp_dtls FROM emp
I want to create a report by using one field and one text as columns name in layout but display the all the columns. I mention the 5 column names in query.how can I write function in summary column.
I am running a fairly busy Oracle 10gR2 DB, one of the tables has about 120 columns and this table receives on average 1500 insertions per second. The table is partitioned and the partitioning is based on the most important of the two timestamp columns. There are two timestamps, they hold different times.
Out of these 120 columns, about 15 need to be indexed. Out of the 15 two of them are timestamp, at least one of these two timestamp columns is always in the where clause the queries.
Now the challenge is, the queries we run can have any combination of the 13 other columns + one timestamp. In reality the queries never have more than 7 or 8 columns in the where clause but even if we had only 4 columns in the where clause we would still have the same problem.
So if I create one concatenated index for all these columns it will not be very efficient because after the 4th or 5th column the sorting would no longer be very useful and I believe the optimiser would simply not use the rest of the index. So queries that use the leading columns of the index in sequence work well, but if I need to query the 10th column the I have performance issues.
Now, if I create multiple single column indexes oracle will have to work a lot harder to maintain all these indexes and it will create performance issues (I have tried that). Besides, if I have multiple single column indexes the optimiser will do nested loops twice or three times and will hit only the first few columns of the where clause so I think it will kind of be the same as the long concatenated index.
What I am trying to do is exactly what the Bitmap index would do, it would be very good if I could use the AND condition that a Bitmap index uses. This way I could have N number of single column indexes which the optimiser could pick from and serve the query with exactly the ones it needs. But unfortunately using the Bitmap index here is not an option given the large amount of inserts that I get on this table.
I have been looking for alternatives, I have considered creating multiple shorter concatenated indexes but this still would not address the issue since many queries would still not be served properly and therefore would take a very long time to complete.
What I had in mind would be some sort of multidimensional index, I am not even sure if such thing exists. But essentially it would be some sort of index that could serve a query efficiently regardless of the fact that the where clause has the 1st, 3rd and last columns of the index.
So considering how widely used Oracle is and how many super large databases there are out there, this problem must be common.
In the OWB mapping,I needed to transfer data in lob table1 to lob table2 .Both tables are in 2 different schema.The table1 has blob and clob columns.The table 2 has same structure like table 1 and the table 2 is empty.
I have created the mapping and connected directly from the source table to the target table.Also , I have created a error table for the target table table. As for the data rule method,I customized the error table to log the non unique rows.
When I start validating the mapping . I got the following error
VLD-3200 Deduplicator cannot contain LOB type columns

I have a table containing hundreds of columns and I would like to be able to qualify my select statements so that only those columns containing a value are returned. Something like:

See attached file for creation script and data load.Each staff member is required to complete at least one task every three years. The source table contains an EID (aka User ID) and a date column for each task with a date of when the task was completed. If a task has never been started/completed the date value is "NULL".
The result set will show the EID, date of latest task completed and if the task was completed within the last 3 years from given date (for example June 30, 2012).

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 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%');
I have a two different Databases. I created a db link in DB 1 to connect to DB 2 and it is working fine when I select data from any table. but I have one table in the DB2 which has a column with user defined data type . so when I try to select this column from DB 2 by using the DB link it gives me this error :ORA-22804 remote operations not permitted on object tables or user-defined type columns.
I've read so many different pages on this topic but I can't seem to get my query the way it needs to be. Here's the query:
select admitnbr, lastname||', '||firstname||' '||finitial, hphone, mobile, wphone, med_rec, dob from patients join schedule using (key_patien) join adtmirro using (key_patien) where appt_state = 'ON HOLD'
Because patients in my database can have multiple appointments "on hold" there are duplicates in the results. I only need 1 record per patient in order to forward this information into an automated dialer to contact that patient. I do NOT want to call the patient over and over again. Once will suffice. I'm trying to make a distinction on the column 'med_rec'. One row per 'med_rec' will be awesome but I can't find a way to create a distinct on that column.
I created a user and granted connect, resource to the user. but trying to select columns from the view USER_HISTORY$,it's showing no value, i tried to login the user several times, but it's displaying no value, any particular reason or any minor mistake?
im trying to select columns from different tables dynamically in a function . The parameter for the function will be table name and column id's, In this number of columns may vary . Is it possible to have dynamic %rowtype to store the cursor value in it.
Our DBA set up a Heterogeneous Service to one of our MS SQL Servers and we can use a DB Link to SELECT a table from the SQL Database. This works just fine but the problem is any nText column on the SQL Database Table doesn't appear. All the columns are shown EXCEPT the nText columns.
how to correct this? We need the ability to select the nText columns also.
i have two tables test1 and test2. i want to update the column(DEPT_DSCR) of both the tables TEST1 and TEST2 using select for update and current of...using cursor.
I have a code written as follows :
DECLARE v_mydept1 TEST1.DEPT_CD%TYPE; v_mydept2 TEST2.DEPT_CD%TYPE; CURSOR C1 IS SELECT TEST1.DEPT_CD,TEST2.DEPT_CD FROM TEST1,TEST2 WHERE TEST1.DEPT_CD = TEST2.DEPT_CD AND TEST1.DEPT_CD = 'AA' FOR UPDATE OF TEST1.DEPT_DSCR,TEST2.DEPT_DSCR; [code].......
The above code when run says that it runs successfully. But it does not updates the desired columns[DEPT_DSCR].
It only works when we want to update single or multiple columns of same table...i.e. by providing these columns after "FOR UPDATE OF" I am not sure what is the exact problem when we want to update multiple columns of different tables.
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
The below sql is giving different number of result sets while adding further columns in select clause.i.e After adding the columns 4,5,6 in the below query its giving different number of result set.In this case the result set count would be 5.
Before adding the columns 4,5,6,the result set count was 11.
