View 2 RepliesUsing the HR schema, I'm trying to write a query which will display the names and salaries of those employees who earn the highest salaries in their respective departments.
I wrote the query:
SELECT first_name, last_name, salary
FROM employees
WHERE salary =
(SELECT department_id, MAX(salary) FROM employees GROUP BY department_id);
However, this query does not execute correctly but I'm not sure why?
Query : select * from scott.dept where deptno=10;
Result
DEPTNO |DNAME |LOCATION
-------|----------|----------
10 |ACCOUNTING|NEW YORK
But i want the above resultset as below,
COL1 COL2
----------------------
DEPTNO | 10
DNAME | ACCOUNTING
LOCATION | NEW YORK
writing dynamic sql query for swapping names:
the output shuld be like that
input output
a a
a b b a
a b c c b a
a b c d d c b a
i have writen it in static form by using instr,substr.But i m having difficulty in making it dynamic by using select statement.I have to make it for retrieving data from database.
I have limited permissions and am unable to create temp tables.So I would like to use a cursor to "create" a table of sorts then access/query it. But this "table"/cursor would have no column names so how do I refer to the columns? Is there a way to refer to a column by column number rather than column name in a query:
select column1 from tablename where column2 = 'abc'?
Is there a way in a query/update/insert to refer to a column by column number rather than column name?
declare
cursor c1 is
select 'abc', '8-Apr-2013', pk_id from EMPLOYEE where pk_id = '153'
UNION
select '1xyz', '4-10-2013', pk_id from EMPLOYEE where pk_id = '154'
c1_val number;

I have written an SQL which will dynamically generate the Select statement with from and where clause in it. But that select statement when executed will get me hundreds of rows and i want to insert each row separately into one more table.
For that i have used a ref cursor to open and insert the table.
In the select list the column names will also be as follows: COLUMN1, COLUMN2, COLUMN3,....COLUMNn
find below the sample
TYPE ref_csr IS REF CURSOR;
insert_csr ref_csr;
v_select VARCHAR2 (4000) := NULL;

I want to load query result into .xls file with column names by using plsql.
Like this i need to generate 4 files and zip it then send mail with attachement of that zip file.
Can we automate in PLSQL? If it is possible pls share the script.
Ex: select ename,eno,dept,deptno,sal,hiredate from employee;
ENAME ENO DEPT DEPTNO SAL HIREDATE like this we need to store the query result into .xls file.
is it possible to use the records returned by a query as column names in a select query.
select (select column_name from dba_tab_cols where table_name='V_$DATABASE' and column_name like '%CONTROL%')

exp toys/toys@orcl file=20121103TOYs.DMP TABLES=(HIMAN) /* Particular table is taken*/
3) i log in to toy schema
imp toy/toy@orcl file=<dump file name> TABLES=(HIMAN) INDEXES=N IGNORE=Y
i tried the above statement it taken so much of time..
Later i tried
I log in to toy session
i rename the table with other name.
later i imported
imp toy/toy@orcl file=<dump file name> TABLES=(HIMAN) IGNORE=Y FULL=Y

I am trying to join column names from a table with data from a different table. I think i should be able to pass the parameter to a 'select list' in a query. Look at my sample data below. And the data in sales table can grow till 15 rows and similarly corresponding columns in saleshist.
CREATE TABLE SALESHIST
(
PRODUCT VARCHAR2(30 BYTE),
Q1 VARCHAR2(30),
Q2 VARCHAR2(30),
Q3 VARCHAR2(30),
Q4 VARCHAR2(30)
)

The table tbl_completed has two columns, id and completed. I have created a query that does provide me with the result set that I need, but I need to pivot the rows into columns. So instead of a result set to look like this:
select completed, count(completed) as theCount from tbl_completed group by completed;
COMPLETED THECOUNT
Y 772
N 720
I need a result set to look like this:
COMPLETED,Y,N
THECOUNT,772,720
The best solution that I have discovered is this, but I figuring their might be a better way.
select
(select 'THECOUNT' from dual) as COMPLETED,
(select count(completed) from tbl_completed where completed = 'Y') as Y,
(select count(completed) from tbl_completed where completed = 'N') as N
from dual;
COMPLETED,Y,N
THECOUNT,772,720

View 2 Replies View RelatedWhat I am trying to do is print out page that displays all of the column titles and the data under them for a query given by the user. It is then going to be put into an excel spreadsheet.
I've done this before with Java, simply by using the getMetaData function, but I can't seem to find an alternative for PL/SQL. It seems at the very least I need to know the number of columns in a query, but that would defeat the purpose of this.
Is what I am trying to do even possible or is knowing the column names an absolute necessity when printing table data?
Why Oracle allowing the Built-in function names as column name in data base table
Ex :
create table to_char
(to_number number(8) , to_char char(20) , to_date date ,substr varchar2(20))
I have question on the following, that gets defined for the bad file and the log file

I have a requirement of pulling the data from a field in horizontal form of Advanced Supply Chain Planning responsibility(ASCP). When I go into help-> Diagnostics, it shows the block name of the form as 'Horizontal Plan' and field name as 'Pivot Table'. Not pretty sure on how to pull the data source into horizontal form with the info I have.
View 3 Replies View RelatedHave got basic form on a table and have a textarea which holds Notes added by user.
So Notes database field is updated on Save / Apply changes button being pressed.But would really like any text added / appended to the Notes field to be prefixed by userid and date / timestamp.
Is it possible via dynamic actions or Javascript to have any new text added / typed to be auto prefixed as per above.
Would only want the first key press in the filed to trigger the auto-prefix and if added text was deleted then the auto prefix to be deleted as well ?? If user doesn't press Save / Apply changes obviously want to leave existing Notes as is.
I need a query to retrieve a particular string from all the columns and all tables in a specified schema.
For example:i had a value "Current" in a particular column in a particular table. i need to find this value if i don't know the table name and column name.
base on performance it is better to retrieve data from view or mention the table names directly?
I have a select statement in from clause one of my table is view (which is having data collected from four tables) my question is whether performance of querry will be improved if i use directly all tables( four tables of a view) instead of a view
