How do I add a column (Status) to a select query based on the data returned.
Select Col1, Col2
from
Table 1, Table 2, Table 3
Where
Table 1.Key1 = Table 1.Key1 and
Table 2.Key1 = Table 3.Key1 and
Table 1.Col1 in ('xyz','yty','ttr')
Output Expected:
Col1 Col2 Col3(Status)
xyx 1mst Sucess
yty Null No Data Found
ttr Null No Data Found
The Col1 value yty and ttr does not exist in the database
I have a stored procedure that updates a series of columns (set at varchar(500) just to ensure there is ample space for whatever data is inserted into it) .Once it has updated though I've wanted to trim the column width down to the maximum size of the column value. I determine the max size of the column length and use that in a pl/sql command to ensure the width isn't smaller than the largest data entry.
When I try to do this I get the following message:
ORA-01441: cannot decrease column length because some value is too big
Now after hunting this down it seems as though you cannot decrease the size of a column once data has been inserted into it.
Any success in reducing the column width of a table that has data in it?
Why do I need to do this? I am exporting this table from Oracle into a propriety application and I am trying to reduce teh size of the export table by removing any unecessary space the unused spaces in the column. This will benefit the local app in addition to reducing the impact on the filesystem storage.
I have column names stored in a table(say t1).
Inside a trigger I have to dynamically get the : old. values for only these columns.
This I need because during update trigger on a table (say t2) I am supposed pickup the coumn names stored in t1 and get the : old values of only these columns to insert into a new table .
i have creatd view,in which i need to show the entry of year in column wise,though the data is in row /record wise.By iteration i can manipulate the year in decode function like " (DECODE(a.Year,(select distinct max(year)-1 from BI_BALANCE_SHEET), a.Balance))",but is there any way to chachge the alias name /column name,here is the query
select
SUM(DECODE(a.Year,(select distinct max(year)-1 from BI_BALANCE_SHEET), a.Balance)) as year2010,
SUM(DECODE(a.Year,(select distinct max(year)from BI_BALANCE_SHEET) , a.Balance))as Year2011

I need to have columns dynamically defined in my SQL based on the column values in the table.
Selct emp_no,dept_no,grade from emp;
emp_no dept_no grade
----------------------------------
1 10 A
2 20 B
3 20 A
4 10 C
5 10 A
6 20 C
7 10 B
8 20 C
I need the output as
dept_no Count_A Count_B Count_C
---------------------------------------------
10 2 1 1
20 1 1 2
I can write hard coded sql to get this output but I need the count columns to be generated dynamically as there could be new entries in the grade column later. For example if there is a entry as D for the grade column my SQL should have a column count_D.
I have two string one is comma separated values as a column name and another string which is having the comma separated value corresponding to the column name.
Example:
string1:='col1,col2,col3'
string2:='1,aaple,'2-jul-75'
now i have to create and run a query which will be like that
select * from emp where col1=1 and col2='apple' and col3='2-jul-75'
converting Rows to Column for a specific group.
Following is the query
SELECT Lpad(papf.employee_number, 6, '0') "File#",
papf.full_name,
Decode(ppee.processing_type, 'R', Decode(ppee.element_name,
'Regular Wages USD', peev.screen_entry_value,
'Regular Salary USD', Round(peev.screen_entry_value / 26, 2),
0),
[Code]...
Which gives me out put as
Example 1
Employee Number Name Value Rate Type Type Assignment Id
-----------------------------------------------------------------

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

-------------------------------------------------------------------------------------------------------------------
4 Employee 1 24.04 H Reg Hourly Sal 800 N 5 Yr Bon 1063 N 6 Mon Bon 64

I have a Strange requirement from client data is loaded from excel to Oracle Table- TST_TBL (with Header in Excel)
CREATE TABLE TST_TBL
(
JOB_DETAIL_ID NUMBER,
SHEET_NAME VARCHAR2(100 BYTE),
COL1 VARCHAR2(400 BYTE),
COL2 VARCHAR2(400 BYTE),
COL3 VARCHAR2(400 BYTE),
COL4 VARCHAR2(400 BYTE),
[Code]...
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');
Insert into TST_TBL

So, for lack of a better way to explain it, I need to do the following.
I need a EXECUTE IMMEDIATE to be able to use a CURSOR but its saying its not declared. Is their a way to pass the cursor so a Execute Immediate can use it...
V_SQL := 'REPLACE(V_DATA,'TEST',CUR_DATA.'||V_FIELD||');';
EXECUTE IMMEDIATE (V_SQL);
I know thats just a small part... but it shows the end goal. I need to append a VARCHAR that has the COLUMN NAME I need from the CURSOR. CUR_DATA is the open cursor. V_DATA is just a VARCHAR with text in it.
I have a problem with Dynamic SQL.
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 code:
TYPE ref_csr IS REF CURSOR;
insert_csr ref_csr;
v_select VARCHAR2 (4000) := NULL;
v_table VARCHAR2 (4000) := NULL;
v_where VARCHAR2 (4000) := NULL;
v_ins_tab VARCHAR2 (4000) := NULL;
v_insert VARCHAR2 (4000) := NULL;
v_ins_query VARCHAR2 (4000) := NULL;
[Code]...
How to fetch the column names here
|| ');';
EXECUTE IMMEDIATE v_ins_query;
END LOOP;

Depending on the no. of distinct dates in table 1 i have to make those many columns in table 2. I m trying to write a Query in SQL. If its not possible in SQL give me PL/SQL procedure.
I don't know what column name would there for my new view. so can i use dynamic SQL in View so that I can get correct column name?

i used sql loader to import data from csv file to my db.but every time the columns places are changed.o i need dynamic way to insert data into correct column in the table.

I have an interactive report which contains the columns like
<li>empno
<li>Name
In the above i have "empno" with a column alignment of left and a "Name" with a column alignment of left.
Whether it is possible to override the data alignment that we set in the report according to the value of the application item like
If my application item value is US, then i need the column alignment of both the column"empno" and "Name" to be left and if my application item value is AR, then i need the column alignment of both the column "empno" and "Name" to be right. Whether is it possible to achieve the dynamic alignment to the report data of both the columns "empno" and "Name" according to the application page item value.And also in the case of page item i have a page item with a name P1_NAME in which it has a Element Horizontal/Vertical alignment to left.
I need that element alignment of the page item to behave dynamically according to the application page item, like if the application page item is US then the element alignment of the page item has to be left and if the application page item is AR then the element alignment of the page item has to be right.
I Have an apex page that display a modal window utilizing jquery. In the modal window I have a classic report with a link column that I want to capture its click event.

I have to create a WHERE clause like :
SELECT * FROM wc_claims WHERE part_nbr in l_part_nbr ;
I have three tables:
table A has - user_id, supplier
table B has - supplier, part_nbr
table C , wc_claims, has part_nbr and 78 other columns.
what i need to do is when user logs in with his user_id, he should see only that info from table C, corresponding to his supplier, and the part_nbr.
SELECT supplier from table_A WHERE user_id = 'abc' ;
supp_abc
SELECT distinct part_nbr from table_B WHERE supplier = 'supp_abc' ;
partA, partB, partC,........partZZ
SELECT * FROM wc_claims WHERE part_nbr in (partA, partB, partC,........partZZ );
I have created a function :
create or replace Function wcl_partnbr ( p_supp IN varchar2 )
RETURN CLOB

so that I can use that in the WHERE clause, because one supplier can have thousands of parts...so it works fine, if there are 200 part numbers for one supplier, but above that.. it doesnt.
I having below table :

In a dotnet application user is going to input/select all/any of the above column in where clause.If user has given value for rol column then ref cursor should be :

and/or
If user has given value for cnm column then ref cursor should be :
select * from search_table where rol like <given value> and/or cnm like <given value>

I am working on an application that requires very dynamic access to data. Users will build queries through the interface and the queries will be stored in VARCHAR fields for later use. The function that later uses the query has no way of knowing the field names or data types used in the selection query.
This isn't an issue in any program language that I have used before but in this case, we want to do this in a package within Oracle rather than an external application.
how to reference a field by its location or position in the query.
We need to get the list of fields so we know what each field is named and we need to be able to get at its value dynamically as well. If possible, checking the data type would be useful too but that is less important in this case.If we were doing this in say PHP, we could simply reference the query row and use a command like...
foreach($myrow as $field=>$value)
and this would walk through each field in the row giving us the field name and its value.We need to do this same type of thing in our package.
I need to store a date that will always be x years before the current date. Is doing something like
select sysdate -x from dual
Going to result in any weird issues down the road? Also, because I haven't explicitly specified the date, when queried, will the value always be sysdate - x (What I want to happen) as opposed to dateRowWasCreated - x?
I wrote a simple procedure to copy the create timestamp and create user name to update timestamp and update user name of the same record. (See code below)
This works fine for a hard-coded table and primary key column. However, I cannot figure out how to get this to work with dynamic sql.
All my other procs, which don't use SELECT UPDATE FOR work fine with dynamic sql.
Proc that works:
CODECREATE OR REPLACE PROCEDURE proc_set_upd_columns
IS
CURSOR c1 IS
SELECT *
FROM mytable
FOR UPDATE
ORDER BY mycolumn;
c1rec c1%ROWTYPE;
[code].........
Partial proc that does NOT work:
CODECREATE OR REPLACE PROCEDURE LDEVORE.proc_set_upd_columns (
p_input_table_name IN VARCHAR2,
p_pk_id_col_name IN VARCHAR2)
IS
v_qry_str VARCHAR2(1000);
v_cursor_str VARCHAR2(1000);
v_create_tmstmp TIMESTAMP;
v_create_user_name VARCHAR2(30);
[code].......
finding out which instance is the resource master of a object.Also select * from V$GCSPFMASTER_INFO
returns zero rows.
Does this mean dynamic remastering is disabled???if so which instance will own a object?
