Deleting records from a Database using JTable
Hello!
I have a JTable that displays records from a database and a Jbutton .
If i press the button i want that the record coresponding to selectedRow(from the JTable) to be erased from the database.How can i manipulate selectedRow from JTable to do that?
Pls any suggestions (and if it's possible +code)?
Thanks!
Hi Margot,
Let's assume that you have created a table using vectors. Simply remove the element from the vector at row selected and redraw. Maybe not the greatest solution but should work.
Vector rowData = new Vector();
//read in values for each row
Vector headers = new Vector();
//add your headers
JTable table = new JTable(rowData, headers);
int row = table.getSelectedRow();
rowData.removeElementAt(row);
table = new JTable(rowData, headers);HTH,
Chris

How to delete record from table control using BDC?
Hello friends,
I am running a BDC program to delete records.
I have file with following records and i got these records into t_itab.
Material Plant Start date End date Cost
MQ100001 S001 09/01/2008 09/31/2008 55.00
MQ100004 S002 09/01/2008 09/31/2008 56.00
MQ100008 S003 09/01/2008 09/31/2008 57.00
Now, I have BDC transaction in which table control screen which contains following structure.
MQ100001 S001 09/01/2008 09/31/2008 55.00
MQ100002 S002 09/01/2008 09/31/2008 56.00
MQ100004 S003 09/01/2008 09/31/2008 47.00
MQ100005 S004 09/01/2008 09/31/2008 25.00
MQ100006 S012 09/01/2008 09/31/2008 76.00
MQ100007 S033 09/01/2008 09/31/2008 17.00
MQ100008 S011 09/01/2008 09/31/2008 95.00
MQ100009 S002 09/01/2008 09/31/2008 46.00
I have recorded from SHDB in which first record will be delete.
So, when i loop through t_itab,instead of deleting MQ100001,MQ100004 and MQ100008 from BDC screen,
it is deleting MQ100001,MQ100002 and MQ100004 (first record for each process ).
Which i don't want to.
Is there any facility in BDC to put records on top which i want to delete?
Please guide me.
Regards,
RHOne option is to identify the table and find out the location as the number of row which should be deleted from the table and then in the bdc program instead of postioning the cursor on the row 1(using the statement perform bdc_cursor ....(01)), replace the 01 with the row number.
Second option is that if a filter control is available for the table control, then filter the data each and every time with the material number to be deleted and then delete the first row.

Delete records from internal table using another internal table
HI,
I have two internal tables itab1 and itab2 which have same records initially.Later some records of itab2 are deleted .Then i want to delete those records from itab1 also ie,those records not found in itab2 .Is there any method other than looping.
So that itab1 again becomes equal to itab2.
Thanks in advance.
Sowmya.Soumya,
Itab1 , Itab2 .
Before deleting the records from itab2 move those records to one more internal table itab3.
Now you have deleted records of itab2 in itab3.
SORT ITAB3,ITAB1 by your main key field.
LOOP AT itab3.
READ TABLE ITAB1 WITH KEY key field = itab3-
keyfield.
IF sy-subrc EQ 0.
DELETE itab1 where keyfield eq itab3-keyfield.
ENDIF.
ENDLOOP. -
Delete records from multiple table
Hi,
I need to delete records from multiple tables using a single delete statement. Is it possible ? If so please let me know the procedure.
Kindly Help.
Thanks,
Alexander.Hi Tim,
Syntax of DELETE statement does not allow for multiple tables to be specified in this way. Infact, none of the DMLs allow you to specify table names like this.
Technically, there are other ways of deleting from multiple tables with one statement.
1. "Use a trigger":
What was probably meant by this is that you have a driving-table on which you create a on-delete trigger. In this trigger, you write the logic for deleting from other tables that you want to delete from.
This does mean a one-time effort of writing the trigger. But the actual DML operation of deleting from all the tables would be simply triggered by a delete on driving-table.
2. Dynamic SQL:
Write a PL/SQL code to open a cursor with table-names from which you want the data to be deleted from. In the cursor-for loop, write a dynamic SQL using the table-name to delete from that table.
3. Using Foreign-Key constraint with Cascade-Delete:
This I feel is a more 'cleaner' way of doing this.
Having to delete data from multiple tables means that there is some kind of parent-child relationship between your tables. These relationships can be implemented in database using foreign-key constraints. While creating foreign-key constraint give the 'on delete cascade' clause to ensure that whenever data is deleted from parent-table, its dependent data is deleted from child-table.
Using foreign-key constraint you can create a heirarchy of parent-child relationships and still your DELETE would be simple as you would only have to delete from parent-table.
IMPORTANT: Implementing foreign-key constraints would also impact other DML operations that you should keep in mind. -

How to delete the child record from the database
how to delete a parent and child record from the database can we do it in the servlet and my database is oracle
I'm not sure I understand the question but you could certainly use the JDBC API from within your servlet to access and modify a DB. You could also use an EJB layer to access your DB and accomplish the same tasks.

Problem When deleting record from database
Hi ,
I have a question. Firstly I'm using VB
I have a problem about deleting any record from access database , That's the code I'm use it for add new item and it's work but it's not work when I tried to edit any rows " it's not want to Save" but work for add new Item.
Try
Me.Validate()
Me.CustomerBindingSource.EndEdit()
Me.CustomerTableAdapter.Update(Me.KonoDataSet.Customer)
MsgBox("Update Successful")
Catch ex As Exception
MsgBox("Update Failed")
End Try
And That's my code for Deleting any record from database But it's not work and that's a problem.
CustomerBindingSource.RemoveCurrent()
CustomerBindingSource.EndEdit()
Me.CustomerTableAdapter.Update(Me.KonoDataSet.Customer)
Can anybody help me about that issue ?Hi kono20006000,
Your issue seems really strange. I would recommend you make a troubleshooting.
1.Made sure your code works with the single copy of the database. You could check if it scans hard drive for the database file name and check if it modifies dates on found files. You could check if you operate with the same database.
2. Use the application update the record at the form_load event to see if it would work correctly.
3.Check the table in update statement and the table in add statement.

Edward

Delete record from the form and from the database
hi,
i want delete record from the form and the database ,but the record is only delete from the from !!!
this is my code :
if //condition then
delete_record;
commit;
end if ;
Any solutions ??
thnxYou have unique key field(s) on the table you are trying to insert which actually restricts you from inserting the same value again.
When you are deleting the record and issue commit there is a record to be inserted in the table which is a duplicate that's why you are getting this unique error.
As oracle is not able to insert your commit fails and stops your deletion of record from table -
Deleting Record from Database in PHP
I'm trying to figure out how to delete a record from my
database. I already have a recordset with my form selected. But
when I try to add "Delete Record," I can never seem to figure out
why it won't delete anything when I load the page in a browser, it
won't even go to the page I told it to go to after it deletes a
record. My guess is it's what I'm entering in the "Delete Record"
part of it, any help would be great. Also, my id is primary key if
that helps. Thanks ahead of time.edwin@aw wrote:

Delete old records in oracle database using jobs
Hi,
will it be possible to delete old records in oracle database using jobs
need to delete old records on weekly basis and rebuild my index.
Thanks!933633, While it is possible to do a great deal with the dbms_scheduler your shop should have a scheduler like CA Unicenter that is used to run the application job schedules. Purge jobs should probably be part of the normal application schedule rather than contained in the database, if your shop has a scheduler in use.
As far as rebuilding the indexes after the purge keep in mind that freshly rebuilt indexes often have to split when inserts are performed due to the fact the compacted index blocks do not have room to hold the newly inserted keys in the appropriate locations. So just because you purge weekly does not automatically mean the indexes should be rebuilt weekly. You need to look at the index key DML pattern and at the total percentage of the index that is held by deleted rows.

How to select first several records from a database table by using select?
Hi,
I want to select first 100 records from a database table by using select clause. How to write it?
Thanks a lot!hai long!
well select statement is used to retrive
records from the database.
following is the syntax to be used.
1) select * into corresponding fields of itab from basetable where condition.
endselect.
ex: select * into corresponding fields of itab from mara
where matnr >= '1' and matnr <= '100'.
append itab.
endselect.
select * is a loop statement.it will execute till matnr is less than or equal to 100.
note: you can also mention the required field names in the select statement otherwise it will select all the field from table mara.
note: itab means your internal table name.
hope you got the required thing.if it really solved u r problem then award me the suitable points.<b></b> -
I need the code to delete record in the database not in the form???
I need the code to delete record in the database not in the form...
because when i execute a form always insert the datas in the data base but i want insert value on a text file and delete in the data base the record whith this value of text file.
i'm spanish an my english is bad sorry.
thank, javierWell, I fail to understand why you want to complicate easy things, but anyway you can do that by using TEXT_IO within Forms to create text file (see Forms builder help), and UTL_FILE package to read it within Pl/Sql : you could create a stored procedure, and call it from Forms passing the file name as parameter. See UTL_FILE documentation
