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 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;
[Code].....
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 want the output from two tables with rows to columns and generate dynamic basing on the columns.
For example: Table A (a1) , Table B(a1,b1)

1 1 x
2 1 y
3 2 a

o/p: Columnname col_1 col_2 col_3

a1 b1_1 b1_2 b1_3
----- ---------------------
1 x y
2 a b c
Columns should be generated based on the second table second column.

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'

After the Data is loaded, we see data look like the above.
(1) Always COL3 column name have data value as 'Gen1' which is the indication for us from where data starts. But Gen1, Gen2, Gen3 etc... is dynamic. ie. This month we get gen1 and gen2 columns followed by null value in a column. Next month we get gen1,2,3,4 followed by null column.
(2) Null Column indicate us that there is a break in the column.
(3) Then next we need to look for next group of data (Monthly) and then insert into the same table again with different sheet_name column.
(4) Next for Quater and then YTD. None of the column Values are fixed and its all dynamic.
If you load the below data, you will come to know what i am looking for. I tried using UNPIVOT. But couldnt able to achieve it. Is there an option to do it in sigle query? or Do I need to go for Stored Procedure?
Insert into TST_TBL
(JOB_DETAIL_ID, SHEET_NAME, COL1, COL2, COL3,
COL4)
Values
(100, 'Wire_1', 'Gen1',
'Gen2', 'Gen3', 'Gen4');

Is it possible to define a cursor using dynamic sql. Reason being is, I want to fetch data from 4 diffrent tables but dont want 4 diffrent cursors for this purpose.
I have a procedure that takes an in parameter . Cursor is declared in this procedure. Again is there a way to use dynamic sql so that this cursor declared in procedure uses all 4 table one at a time i.e cursor c1 is select * from table_name(I want this table name to be updated every time with new table name).
I'm trying to replace the variable value v_tblname in dynamic SQL. But not able to escape the single quotes character.
DECLARE

v_sqlcols1 VARCHAR2(2000);

BEGIN
v_sqlcols := q'[SELECT LISTAGG(COL,',' ||CHR(10)) WITHIN GROUP (ORDER BY COL)

l_query := 'SELECT sedol ' ||
'FROM integration.tmp_attributed_sedol ' ||
'WHERE ' || p_field || '=''' || p_ref_number || ''' ';
by using the execute immediate or any other command, how can i check whether the query returned any rows or not?
small piece of PL SQL code. how to make this query.Requirement is that a concurrent program is run with parameters and one of them i_num_org_id is non mandatory so it can come as NULL...Now in an existing code which i have to change, it uses a query as
SELECT xyz
FROM abc_table
WHERE <various conditions>
AND DECODE(i_num_org_id,NULL,1,table.organization_id) = NVL(i_num_org_id,1);
Now with the above way, if the program is run with some value for i_num_org_id or run as normal query (with NULL as the value) inside a PLSQL procedure/package then it runs fine.This query if you run in Toad etc then too it will work fine but if it is made a dynamic SQL and then used as either EXECUTE IMMEDIATE or opened as a cursor then we get a "Missing expression". I created this small anonymous block to test this and this will go into missing expression error
declare
l_num_org_id NUMBER := NULL;
l_temp VARCHAR2(100);
l_sql varchar2(1000);
begin
l_sql := 'SELECT '||''''||'abcd'||''''||'
[code].....
how i can reformat this query so that even if NULL value comes for i_num_org_id then it is handled.I am aware about CASE but that cannot be used in WHERE clause i guess.

ORA-00905

Cause: A required keyword is missing.
Action: Correct the syntax.
But when I check my stack trace table to see what the actual query string looks like, I see this
Quote:
SELECT sedol INTO l_attributed_sedol_code FROM integration.tmp_attributed_sedol WHERE CLIENT_LEDGER_REF='LEAE057090' AND ROWNUM=1
There's nothing wrong with that, is there? It executes fine if I try it manually.
I have a dynamic query which has this clause in it: WHERE [COLUMN NAME] IN (' || theString || ')
My problem is that theString is being passed in through a C# call and the variable is a bunch of strings concatenated together and separated by a comma. Ex: theString = "'val1','val2'"
How many quotes are supposed to go around val1 and val2?
I've tried the following and none work:
'val1','val2'
''val1','val2''
''val1'',''val2''
'''val1'',''val2'''
''''val1'',''val2''''
When I run the procedure in Oracle it works with '''val1'',''val2'''
I have to use bind variable for dynamic sql in a procedure. Is there a way to have control on these values. Say for example:

I think dynamic sql is not executed because of the pipe character in the sql statement.
I have a Pro*C program, which uses a dynamic query. The dynamic query is opened using result of another static cursor( 5 fields say , :a, :b , :c, :c, :d).
I am modifying the dynamic query and adding UNION for some requirement , which makes this dynamic query exactly double in size. ( means 2 set of prev. queries are joined by UNION, with one extra condition though).
The question is , Do I need to pass 2 set of variable to open the dynamic query now?
Like earlier , program was passed with (:a, :b , :c, :c, :d)
so now i should pass (:a, :b , :c, :c, :d , :a, :b , :c, :c, :d)?
