Updating, Adding, or Deleting rows from a query
So, I've got this page that originally was made of four
different forms. It worked great. But, then the client asked that I
"idiot proof" the page.
Originally, I had a form that enclosed a one-line table (with
Add & Clear buttons on the end) that took seven fields and
"added" a new record to the "tbljob" table.
That was followed with another form that created a table from
the results of a cfquery and listed all the rows from tbljob (with
Update/Delete buttons on the end of each row).
This worked fine when it was two separate forms. Now, I'm
trying to use only one "form" while displaying the two tables. The
buttons are now done with Javascript (so there are dialog boxes).
The problem is that I am getting a CF error message because the
insert, update, and delete commands are trying to pass the contents
of the fields as comma-delimited lists rather than the single data
item that is actually in each field. I am passing a hidden field
with each row that contains the "job_id".
I know the problem is that I'm not identifying each row as
being unique. I guess it's like I'm passing an "array" of data
rather than just a "row".
Basically, I just want to be able to display a blank row for
adding records followed by multiple rows from a query. The blank
row needs to have "Add" and "Cancel" buttons at the end and the
multi-row part has to have "Update" and "Delete" buttons on the end
of each row and manage the appropriate records.
It's got me stumped. TIA.
What you can do is try using <cfloop> to insert, update
and delete your information.
For instance deleting the information try this.
<!---- Delete Jobs---->
<cfloop index="JobIDs" list="#Job_ID#" delimiters=",">
<cfquery name="delteall" datasource="dbsource">
DELETE
FROM table
Where job_Id = #JobIDs#
</cfquery>
</cfloop>
Do the same for your inserting and updating.
Because what CF see is job_id = 1,2,3,4,5,6,7,8,9
SO you are looping over a list = #job_id# and delimiter is "
, " and we are calling the index JobIDs. JobIDs are the values - 1
2 3 4 5 6 ....
I hope this helps. As for the displaying of the images, use
if then statements:
<cfif isdefined("edittable") and edittable eq '"y">
Then display the query and outputs for the editing options
<cfelseif isdefined("deletetable") and addtable eq "y">
The dispaly the query and outputs for adding options
<cfelse>
Then display the query for outputing the delete options
</cfif>
So your link will have soemthing of this sort <a
href="samepage.cfm?deletetable=y">Add Table</a>
Hope this helps,

Want to delete Rows from SAP Query which have u20180u2019 or blank values
Hi Experts,
I have made one sap-query, in that I have added some additional fields, after that I am getting some blank or u20180u2019 values in some rows, can anyone tell me how to delete those rows which have u20180u2019 or blank values.
Regards
Mahadev RoyHi mahadev
You must be fetching data from SQ02 in some internal table.Delete values from that internal table.
Also as you are fetching records from SQ02 then in the select statement you can put this condition of '0' and blank
so that you will get appropriate result.
Thanks

Cannot DELETE rows from LOV on running...is it a bug ??
One of the features I appreciated in the new version of JHeadstart is that we can now insert, modify and delete rows on LOV (even in the database).
We have just to check on Lookup properties :
Multi-row insert allowed
Multi-row update allowed
Multi-row delete allowed
I cheked all of them and on runnig I could insert and update records in LOV.
When I tried to delete records from LOV the system display information message "nothing to save" and in fact no records were deleted.
Normally since I checked the delete property it should be possible to delete rows from LOV
thanks for any HelpMonta,
I could reproduce this, it is a bug. Added to the fix list for the next release.
Thanks for reporting,

Unable to delete rows from Target.
Hello everyone,
I am unable to delete rows from target data store. Here is what I have done.
Source Oracle 10g - staging 11g - Target Oracle 11g
I have implemented consistent set CDC on data model in staging and added 2 tables to CDC and turned on the journals . Both tables A and B are joined together via Column E (primary key of table A). Table A is the master table(has foreign key). Table B is child table. Target column consists of all the columns of both table A and B.
Following is what I am able to do and not to do
ABLE TO DO. If data is inserted into both or any of journalized tables I can successfully load the same in target by performing following steps. 1. Extend the consistency window at model level. Lock subscriber. Run the interface with any source table marked as Journalized data only. Unlock subscriber and purge journal.
ABLE TO DO. If data is updated in any of the journalized table, along with the steps mentioned above I can execute two interfaces. In one Interface table A marked as journalized data only Joined with table B and in second interface table B marked as Journalized data only joined to table a.
NOT ABLE TO DO If data is deleted from one or both tables it shows up as journalized data in JV$D<tablename> marked as D with date and subscriber name but when i run the interface by extending the window , locking subscriber executing both interfaces, unlock subscriber purge journals. no change takes place is Target. After unlocking subscriber step, journalized data gets removed from JV$D view. Please let me know what I am doing wrong here. How can rows delted from source can also be deleted from TARGET?
NOTE : In the flow table SYNC_JRNL_DELETES is YES
In moel under jounalized table tab Table have following order Table A folloed by Table B
Thanks in advance
GreenwichSorry I still do not get it. when you say "Its a legacy app", are you talking about the VB.NET app ?
If so then I repeat my self :-) Why not to connecting to the SQL server directly?
* even if you need information from several databases (for example ACCESS + SQL Server), in most cases, it is much better to connect directly and get each information to the app. Then in your app you can combine the information and analyse it

Access app is the legacy app. -
Prevent user from deleting rows from all tables in his own schema
Hi,
How can I prevent user from deleting rows in all tables in his own schema.
I want the user to not able to delete rows from any existing or new tables that might be added in the future.
The user does not have the "DELETE ANY TABLE" system privilege.
Please advise.
Thanks.Nowadays, I'd also avoid triggers (if possible).
Sometimes, when I daydream, I'm rewriting a few applications that I've contributed to as a newbie, and I'm very ashamed of it nowadays.
From what I've experienced, in retrospective, the emphasis on teaching 'Oracle stuff' has been lying far too much on PL/SQL row-by-row oriented processing instead of letting Oracle 'crunch' sets at once.
Most of my debugging hours ended up in discovering one or more database triggers 'doing stuff automagically'.
Another nice blogpost: http://rwijk.blogspot.com/2007/09/database-triggers-are-evil.html
Regarding OP's question:
I would just rethink/reconsider this requirement completely.
Correctly implementing privileges and roles seems the best way to go, yes.
Triggers? Nah...
pre-post-edit, noticed thread got updated just before posting
Don't know what you mean with 'namedropping', but I think it's legitimate to point other readers to interesting Oracle related opinions/articles that do have a technical background and lots of interesting examples.
post dreaded OTN outage edit (from here)
Again: I would just rethink/reconsider this requirement completely.
Both trigger/vpd are being used to hide a design flaw here. -

Oracle deleting rows from tables starting with the name PQ
hai friends
we are given access rights to delete only tables starting with PQ. HAVING PQ_NUM as primary key for all the PQ tables.
totally we have 6 tables. PQ_01,PQ_02, PQ_03,PQ_04,PQ_05,PQ_06.
ALL This tables will have one primary key. for example pq_01 willl have pq01_num as primarykey and pq_02 table will have pq02_num as primary
key.
pq01_num value will exist in all the primary key of pq tables.
i want query to delete rows from the pq tables based on the input value i give.
for example if i give primarykey value 122 then that value in pq tables should be deleted.
One more problem is there. pq_06 table does not have pq02_num column. here the column differs. it is pq06_num_req.
so give your idea of deleting the rows from pq tables
waiting
SI dont have access to databse,this is untested
declare
v_cmd varchar2(2000);
columnname varchar2(30);
input_value number:=??;
tabowner varchar2(30):=???

Hello,
I've got a JTable which is based on a 2-dimensional array, which contains my data. Now I want to delete several rows from the JTable. There's the possibility to modify my data-array by creating a new array which doesn't contain anymore the datasets I want to delete. Afterwards I can redraw the table and my rows are deleted. But I think that's a very complicated way to delete rows from a JTable. Can anybody tell me whether ther's an easier way to do so ? I'd really be pleased...
Thanx,
FindusWhen you create a TableModel using a two-dimensional array or a Vector of Vectors, a DefaultTableModel is created and it stores the data in its own Vector of Vectors. The DefaultTableModel supports methods for adding/removing rows of data. To remove the first row in the table you would do something like:
DefaultTableModel model = (DefaultTableModel)table.getModel();
model.removeRow( 0 );
Note: once you create the TableModel you should set your array to null as it is not used anymore. -
Deleting rows from very large table
Hello,
I need to delete rows from a large table, but not all of them, so I can't use truncate. The delete condition is based on one column, something like this:
delete from very_large_table where col1=100;
There's an index (valid, B-tree) on col1, but it still goes very slow. Is there any instruction which can help delete rows faster?
Txh in adv.
A.Your manager doesn't agree to your running an EXPLAIN PLAN? What is his objection? Sounds like the prototypical 'pointy-hair boss'.
Take a look at these:
-- do_explain.sql
spool explain.txt
-- do EXPLAIN PLAN on target queries with current index definitions
truncate table plan_table
set echo on
explain plan for
<insert query here>
set echo off
@get_explain.sql
-- get_explain.sql
set linesize 120
set pagesize 70
column operation format a25
column query_plan format a35
column options format a15
column object_name format a20
column order format a12
column opt format a6
select lpad(' ',level) || operation "OPERATION",
options "OPTIONS",
decode(to_char(id),'0','COST = ' || NVL(to_char(position),'n/a'),object_name) "OBJECT NAME",
cardinality "rows",
substr(optimizer,1,6) "OPT"
from plan_table
start with id = 0
connect by prior id = parent_id
There are probably newer, better ways, but this should work with all living versions of Oracle and is something I've had in my back pocket for several years now. It's not actually executing the query or dml in question, just running an explain plan on it. -
COuld anyone tell me how to delete rows from a table which has millions of rows.
TIA,
Oracle userif you are deleting all the rows, use "truncate table" in sql*plus.
or if you are deleting all but a handful of rows, then copy the rows you still want to a spare table, drop the original table, and rename the spare table back to the original table's name.
hope this helps -
Delete rows from table...Bizarre problem.

i HAVE this bizarre problem.

Hi,
Anyone knows how dynamicly delete rows from Tabular Form (on button click, button is as item)?
Thanks.I am in a great fix. We had a test instance.. and we had a version apex 3.2.. But when the same application has been uploaded to prod.. we used apex 4.0.Why on Earth would you do this? The whole point of the testing is to verify that the application will work in the production environment: the first requirement for this is that the test and production environments are equivalent.
has any body is facing the same issue as mine..Yes, as is easily discovered by searching the forum...see Delete button doesn't work in tabular form after upgrade from APEX3.2 to 4. -
Add/Delete rows from ALV-grid
Hi to all,
i have 2 questions concerning alv-grids:
i have an alvgrid displaying a table and what i need is some functionality to add or delete rows from the alvgrid - how can i do that ?
within one row i have one field containing the status and i want to be able to select the status from a combo/dropdown-field and set it for this particular row.
thanks in advance!Hi,
Report BCALV_EDIT_04 shows how to append and delete rows.
Report BCALV_EDIT_06 shows drop down list for cells in a column.
These report should be available in any R/3 system including all ABAP Preview versions.
Hope this can help.

Hi everyone!
I want to know if it's posible to group the rows from a query into a unique row. Example:
SELECT Field_1 FROM Table_1
Returns the following fileds:
Field_1
A
B
