Inserting a column into JTable

I can insert a column at the end, and then move it to the position i want it. When i have done this and print out the headers from the columns in the column model, then from index 0 up to (say) 6 are as i want them, with the new column at index 4.
However, when i add a new column again, then the previously added column has an index of 6 and so isn't displayed in the position i want it.
I'm using the moveColumn method as I have found people saying to use, it's just it doesn't seem to stick!
Any ideas?

Adding a new column to a DefaultTableModel fires a special TableModelEvent. Because of that the JTable reinitializes its TableColumnModel and any column movements are undone.
You can call "setAutoCreateColumnsFromModel(false)" on the table but then you must update the TableColumnModel manually. The best solution is to build a table model with all necessary columns and to remove all TableColumn-Objekts from the TableColumnModel which should not be visible at first; adding TableColumn objects later wont alter the positions of the other columns.

Inserting multiple columns into database using dbtool set

I have a labVIEW program that is currenly simulating voltage and a current signal using the DAQ Assistant. I'm using the database connectivity toolset. I am currently able to insert one signal into the database converted to a float(I can insert both into the same column as bianary but it needs to be stored as a usable format and in seperate columns.)
The problem I am having is at the DB Tools Insert Data block. I have the connection, dbTable, error code, and create table boolean being passed into it. Where I am a little lost is how to set the columns I want to store the multiple signals into.
If someone could break that part down for me that would be great. In short, I want to store voltage(channel0) and current(channel1) from the DAQ Assistant into their own respective columns in the db.

Don,
This particular forum is specific to TestStand, not LabVIEW or Multifunction DAQ. You may have a better chance at responses by posting to either of those forums rather than here.

Insert single column into oracle table

i have a table t1 in whcih only one column is there
Create table t1
a number);now i need to load this column from a excel sheet.
it have many rows and many column but need only corresponding column.
please suggeest any way apart from external table and sql laoder.
thanks

No problem if you have thousands of rows.
Say the value you want to insert is in column A of your excel file.
In column B use the following formula:
=CONCATENATE("insert into t1 values (";A1;");")And copy this formula to all other rows.
Then select all the B column, copy it and paste it in a notepad file.
Call the file as you want, for example c:\ins.sql
open sqlplus and run
SQL> @c:\ins.sqlAt the end don't forget to commit...

Insert 3 columns into winSQL

I have an excel spreadsheet that has 3 columns and I need
those three
columns inserted into a Win SQL table that has more than 3
columns.
I know how to export the Excel file to get a comma delimited
or other
compatible formats, I just don't know what the insert
statement would
look like in order to get it into the SQL database using
query analyzer.
I've done something similar to this but I lost the notes I
had for doing
this.
Also, I need one of the fields to be added into another
table. It would
be cool to be able to do both at the same time but doing one
table at a
time is no problem either.
Thanks for the help...

Inserting a column into the title of a graph

Hi,
I have a pie chart with a title. I also have a drop down column in the graph prompt area showing the months.
I need the month value to show within the title, and for it to change when the user chooses another month
from the drop down list.
Any help would be really appreciated.
Thanks,
- Jenny

Let's see if I can figure this out and type it up before the real GREP masters show up...
\d{9} will find groups of nine digits, but what you actually need to do is find groups of five digits followed by groups of four digits.
\d{5}\d{4}
And you need to separate them into groups:
(\d{5})(\d{4})
so that in the Change field you can use "first found group" and "second found group":
$1-$2

How can I copy and then insert a column in Numbers 09

I have a column in a Table that I would like to copy and then insert this column into another existing table on the same sheet. I don't want to copy and paste this, but rather insert it between existing columns.
Thanks
Eric

Thanks SG,
I have reverted back to 09' because of the nonexistant functionality of 3.0. I tried the option method you mentioned and it doesn't seem to work in 09'. Have you tried it in this version.
Eric
PS 3.0 has beautiful interface, perhaps they will add some functionality someday.

Scroll Fix Column in JTable

I have see a lots of examples of whow to create fix column into JTable.
But all the examples have the same problems.
When I wont to scroll over the fix column the vertical scroll bar of the no fix column dont move, so the no fix column dose not move and the fix columns and no fix columns aren?t alined.
If sameone have same example, send it please !!!!
Thanks !!!
Pablo

In a recent project I've had the same problem.
After a long research at the Swing forum at java.sun.org and google I found out that
1. Currently there is no proper Open Source solution
2. All the postings at sun are good concepts, but far away from solutions
3. The only (for me )acceptable commercial solution is the JCTable from Quest (formerly KGroup)
Since I want to have full control over the source code of the table, I decided to collect all the tips from this forums and write my own table.
Here is a first try:
http://jroller.com/resources/kriede/CoolTable.java
The main idea is to have two tables, one for the locked columns (= fixed columns = frozen columns) and one for the scrollable columns. With all the tips from this forum it was more or less a puzzle to make it work pretty.

Inserting a Column on a report

How do I insert a column with fixed contents into a report? I currently have two columns on the report and I'm doing a Union so I need to insert a 3rd column with a fixed text based on the criteria. For example, the inserted column for the first section would say "AAAAAAA", the inserted column for the 2nd section would say "BBBBBBB", etc... How can this be done?

Insert any column into your report and position it where you want your static text column to appear. Click the fx button to edit the column's formula and replace the entire column formula with your desired text enclosed in single quotes.
'AAAAAAA'

Need to use vector to insert data into JTable?

hi
i'm trying to insert data from mssql 2000 into JTable. The number of columns are fixed, but the number of rows are not, since it will depend on how many data retrieved from the database.
The documentation says that vector class implements a growable array of objects, and I've seen some examples using vector such as from http://forum.java.sun.com/thread.jspa?forumID=57&threadID=238597 .
I would like to know, in my case, do i need to set my column and row to use vector? or should i only set rows to use vector ? (since the row size will vary, while the column size will stick to 6).

Because your JTable operation will be done on a table model, the selection of the initial data
structure for the model is almost non-issue. In other words, whatever will do.
See the javadoc for the DefaultTableModel class, which you will eventually use, especially the
construcotr part.

Is this with the Travel database or another database?
If it's another database then make sure your columns
allow nulls. To check this in the Server Navigator, expand
your DataSource down to the column.
Select the column and view the Is Nullable property
in the Property Sheet
If still no luck, check out a tutorial, like Performing Inserts, ...

How can I insert a image into a BLOB column in a table?

I am using forms6i against a 10gR2 database and I have one table with a BLOB column and I try to insert a image into this column. I get ORA-01461 error.
The curious case is that in another table with a BLOB column it works very fine.
What happens with the first table? How can I avoid the error?
Thanks in advance.
