SQL & PL/SQL :: How To Query For Columns Without Using Column Names
Jun 5, 2013I 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;

Feb 8, 2013I 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.

find below the sample

insert_csr ref_csr;
v_select VARCHAR2 (4000) := NULL;

SQL & PL/SQL :: How To Pivot Table So That Rows Become Column Names
May 9, 2012Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit
PL/SQL Release 10.2.0.5.0 - Production
"CORE10.2.0.5.0Production"
TNS for Linux: Version 10.2.0.5.0 - Production
NLSRTL Version 10.2.0.5.0 - Production
See attachment for table creation and table data.
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

Feb 3, 2012What 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?

Sep 12, 2012Have 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.
