Are you doing a job interview where they've given you access to the internet? You seem to be asking interview questions all over the place. If you don't know the answers to the basic questions that you've been asking, then I would suggest that a career in IT is probably not the best option for you.

Hello all:
Using DataGridView connecting to SQL2005 database. I was able to view the dataset on one of the table that I selected.
I would like to use BindingNavigator to save or add a row onto this particular table.
Could someone please give me an example of how i'm going about to do this?
Thanks in advance,

Access uses the standard oledb provider. You still will have through a "Provider=" clause in your connection string.
Hope this gives you a direction to look.

If you know the length, which is seems you do, then use substring
So your code would be something like:
update yourtable set attribute_code = substring(attribute_code,1,10)+'put your new number here'
Make sure you do some good testing before you update the whole table. It might be a good idea to make a copy of the table you are planning on updating.
You can check your update by doing something like:
select substring(attribute_code,1,10)+'put your new number here' from yourtable
Hope that helps.

If you are asking about reseting the table identity once you have deleted all the rows, then use DBCC CHECKIDENT to reseed or reset Identity column.

Can anyone tell me having known the table name, how can I get the column names and their datatype?
I am using the ojdbc14 driver to connect to my Oracle10g database.
My table name is 'orders' and I want to know how many columns it has and of what type.
Is there any query for this?
|
|
|
|
|
to know the column names:
select COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME ='orders'
all the related information would be present when you use
select * from information_schema.columns
try it out!!
