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 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 need to transpose this table to below one. But since my rows in 1 table is dynamic and it will increment each week and month I couldn't get a correct result from unpivot.

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;
Employee Number Name Value Rate Type Type Assignment Id ----------------------------------------------------------------- 4 Employee 1 800 N 5 Yr Bonus 64 4 Employee 1 1063 N 6 Months Bouns 64 4 Employee 1 24.04 H Reg Hourly Sal 64 5 Employee 2 6923.08 S Reg Sal 65 6 Employee 3 5961.54 S Reg Sal 66 6 Employee 3 15000 N 6 Months Bouns 66
I want to convert above out to look like following
Emp Num Name Value Rate Type Type Val 1 Rate Type 1 Type 1 Value 2 Rate Type 2 Type 2 Assignt Id ------------------------------------------------------------------------------------------------------------------- 4 Employee 1 24.04 H Reg Hourly Sal 800 N 5 Yr Bon 1063 N 6 Mon Bon 64 5 Employee 2 6923.08 S Reg Sal 65 6 Employee 3 5961.54 S Reg Sal 15000 N 6 MontBon 66
Example of Query Output 2.
Employee Number Name Value Rate Type Type Assignment Id -------------------------------------------------------------------------------- 4 Employee 1 800 N 5 Yr Bonus 64 4 Employee 1 1063 N 6 Months Bouns 64 4 Employee 1 1345 N Patent Bonus 64 4 Employee 1 24.04 H Reg Hourly Sal 64 5 Employee 2 6923.08 S Reg Sal 65 6 Employee 3 5961.54 S Reg Sal 66 6 Employee 3 15000 N 6 Months Bouns 66
Desired Output from Above Query. As you can see column have increased as one more row for same employee has increased

I want to change space allocation for character columns in my database, So it will store them as 'CHAR' and not 'BYTE'.my character set is
SQL> SELECT VALUE FROM V$NLS_PARAMETERS WHERE PARAMETER='NLS_CHARACTERSET'; VALUE ---------------------------------------------------------------- AL32UTF8 SQL> alter system set NLS_LENGTH_SEMANTICS='CHAR' scope=both;
System altered.I bounced the instance just to make sure
And then I want to see that when I create a table with some varchar2 column,The space for it will be allocated by chars, and not by bytes! However, when I run a check of create table, this is what I get:
trying to update a column in a table which has 3 columns of 16million rows from column in another table which has 1million rows, there is no relationship between the 2 tables.
Table A has 3 columns of 16million rows, the first two columns have 16million ID numbers, the 3rd colunm is currently NULL.
Table B has 1million Numbers, i need to somehow update column 3 in table A using the numbers in table B, it doesnt how many times each of the 1 million numbers are used but i dont want it to just update every row to the same value.
I have 20 tables. In all 20 tables, some of column names are same and some are different. I need to find all column names in all 20 tables that have same names.
INSERT INTO TEST_TBL VALUES( 1000, 2000, 3000, 4000 ) ;
Expected result
A1 1000 A2 2000 A3 3000 A4 4000
A1, A2, A3, A4 are hard coded fixed values.
I could have done this but not a good idea in case table TEST_TBL is not a single row table but an inline query on 1,00,00,000 records with summary functions. In my table I've a summary query instead of single row table.
SELECT 'A1', COL1 FROM TEST_TBL UNION ALL SELECT 'A2', COL2 FROM TEST_TBL UNION ALL SELECT 'A3', COL3 FROM TEST_TBL UNION ALL SELECT 'A4', COL4 FROM TEST_TBL
I need to display dynamically a bunch of categories and I need the SQL algorithm to determine their size and names.
So, I have a table with one column and a variable number of records and I need to display them in GUI in pages, displaying also the page name which should be something like short name for first item to short name of last item in category.
Maximum items per page in 10 but I don't want to simply display blocks of 10 records. If the name of the 8th item starts with B and the name of the 9th item starts with C I want the first page to contain only the first 8 records. Minimum accepted items per page is 8, maximum is 10. The split should be based on the first 2 characters. Page name should be something like: first 4 chars of first item in category - first 4 chars of the last item in category.

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 a problem with a query I'm trying to run. I need to match two columns containing names, first column (NAME1) contains only the surname and the second column (NAME2) contains a surname and initials, with the initials turning up on either side of the surname.
I need to transpose the following table columns to rows and rows to columns...Im not quite sure how to acheive this...I have the following table with fixed number of columns and dynamic number of rows based on date filter in query
MONTH_YEAR RMS RMS_OCC TTL_RMS --------------------------------------- SEPTEMBER 200917790017790 OCTOBER 2009183831278818347 NOVEMBER 2009177901460517762
and I need to display this as
COL1 SEPTEMBER 2009 OCTOBER 2009 NOVEMBER 2009 -------------------------------------------------------------- RMS 17790 18383 17790 RMS_OCC 0 12788 14605 TTL_RMS 17790 18347 17762
I have a tmp table with 6 cols, and data to be inserted is from two other tables. My problem is there the cols of the table are
sid varchar2(10), cob_dt varchar2(10), deal_id varchar2(10), new_val varchar2(10), old_val varchar2(30), amend_col v archar2(50), i have return a proc create or replace

But, till yday it was showing the orignal column name..
I am trying to build an array that contains known column names, 63 columns in all.The idea is to search backwards from 63 down to say 10 to find the first non-blank column.
Then using a loop with the known number of lines print from 1 to last non-blank column.The problem is that it only shows the column names and not the values of the columns.So I am getting 63 lines every time, instead of 20, 30, 40 or however how many fields actually have something.
Here is my declare to_num number; field_name varchar2(15); [code]....
i am practicing to get Dynamic columns as i have learnt from Orafaq SQL/PLSQL forum .i am using Default EMP table...first one is running smoothly as below:
I have one hirarchical query which return the parent to child hirarch level data. it has 11 level child data. i want to create column based on number of child in hirarchy. though i know it is 11 but it can change also.Is there any way i can create the column dynamically
I wonder if there is any way to return the columns of an select with its letters lowercase?
I have a piece of code that creates an script wich returns an SQL result to be confronted with some templates. My template have the column names in lowercase and because It is case sensitive the Uppercase returned by Oracle,
i have list item populated with many table names from a schema. i have grid in oracle forms 10g and i want to fill the grid with at least four/more columns.I want to fire the list change trigger when each time any one table name is selected.
how can i find the columns names dynamically for filling the grid.
