Yes, you can put up to 2Gb of anything you like in there.

Get your image file and return it as a byte array: byte[]
Kunal P wrote: i`l have a fileupload control to browse to the file..
I've not used the file upload control. I'd imaging you'd get some sort of stream object or perhaps it has a method that supplies you with a byte array.

I have already created the tables in access.I want to get the create table queries for the existing tables.
plz help me

I looked into this, and asked my local ACCESS Guru, and he said that this is not possible.
The only thing that comes remotely close is using Tools > Analyse > Documenter...
From this data you could quickly write create scripts yourself.
Other options are copying your MDB file and just removing all of the data. What exactly do you need it for?
I also found that the CREATE TABLE sql statements are not really supported anymore since Access 1997, so you won't find proper syntax of CREATE TABLE in JET SQL in the Help files of Office, look on Google instead.
Visual Studio can't evaluate this, can you?
public object moo<br />
{<br />
__get { return moo; }<br />
__set { moo = value; }<br />

Actually, the poster asked for a solution for Oracle. sysdatabases is for SQL Server (and possibly Sybase?). The concept of server/database is different for Oracle versus SQL Server, meaning I'm not sure of an Oracle solution (assuming you actually did mean database). You might have to look at parsing the tnsnames.ora file or something. I'll post again if I find anything.

Hi,
I have a Insert into Table(ColumName1, ColumnName2, ColumnName3, ColumnName4) Values('value1', 'value2', 'value3', 'value4')
If we dont give the Column Names then by default it takes all the columns.
There can be any number of columns so i wanted to know if There is any way in which i can use ColumnNo's instead of ColumnName in the syntax of Insert into Table.
I am using SQL Server 2000.
Plz help me in solving this problem.

How many times are you going to repost the same question all over the place ? This is not a right approach to ask for help.

If the question is asked multiple times in different forums, there is no collaboration between people answering the question. Every responder would have to find all the posts for the same question to see how's suggested what, or if there is any new information describing the problem, or even if the question has already been completely answered in another forum!

There's no real way to do this, because you can't know which columns you are referencing by position. For instance, the following is valid:
insert into table1(col1, col2) values(@col1, @col2) and the same is also valid:
insert into table1(col2, col1) values(@col2, @col1)

Hi All. Could someone please explain me why when i add the column, and place the text in cell, the text is not displaying?
DataSet ds = DBEngine.GetOurSIS(Program.DB.Connection);
DataTable tbl = ds.Tables[0];
DataColumn col = tbl.Columns.Add("S_trot", typeof(string));
int ColIndex = col.Ordinal;
for(int i = 0; i < tbl.Rows.Count; i++) {
int CurrShipID = (int)tbl.Rows[i].ItemArray[1];
int CurrSumTrot = Program.DB.GetShipTrotil(Program.OurTeam, CurrShipID);
CurrSumTrot = 10;
tbl.Rows[i].ItemArray[ColIndex] = CurrSumTrot.ToString();
}
dataGridSIS.DataSource = ds;
dataGridSIS.DataMember = TblNames.TblNositeliName;

hi can some one help me ...
i want a stored procedure or query for selecting jobs when the user enters keywords ..
i couldnt find out how i can do that with "all words" and "any word"....
|

You can use OR conditions in the where clause of the query.
You will have to provide options of all words or any word in the UI.
According to the user preference you can change where condition in the stored procedure.
Consider following search query --
"some query with multiple words"
Then your where condition can go like this -
where text_data like '%some query with multiple words%'
OR
where text_data like '%some%' or text_data like '%query%' or text_data
like '%with%' or text_data like '%multiple%' or text_data like '%words%'
You can combine these 2 conditions together if you dont want to provide UI.
Then your where condition will be as this -
where text_data like '%some query with multiple words%' or text_data
like '%some%' or text_data like '%query%' or text_data like '%with%' or
text_data like '%multiple%' or text_data like '%words%'

Thanks
Hey i have a stored procedure
where i select the jobs based on LOCATION, FUNCTIONAL AREA, EXPERIENCE and KEYWORDS
KEYWORDS : they can add multiple keywords and there is a DROP DOWN LIST( with options exact phase, any words, all words)
How can i write the stored procedure for these three options...
Can you help me PLEASE....
|
|
|
|

You can send the search query directly in the KEYWORDS parameter and add another parameter to identify whether the keywords are to be searched for exact words or all words or anything else .... Using this parameter value your where condition changes accordingly.

Hi,
i want to lock one of record that one user going to edit it, and dont set permission to other user (in network) to delete or update it
how can i lock record in database that use from some users in network?

Do you mean permanently or just until you finish a transaction?
You can easily lock rows while in a transaction, and they will be released when it is commited/rolled back.
BEGIN TRAN<br />
<br />
SELECT *<br />
FROM authors<br />
WITH (HOLDLOCK, ROWLOCK)<br />
WHERE au_id = '274-80-9391'<br />
<br />
<br />
<br />
COMMIT TRAN

public object moo<br />
{<br />
__get { return moo; }<br />
__set { moo = value; }<br />

MySQL Update for 20,000 rows takes 4+ hours? Is this a bit slow?
I am using the ADO.net driver for MySQL that I downloaded from the MySQL website recently.
My database is not the most optimised I must admit but I can do the same with a text file in about 3 minutes (which is what I have had to resort to so is not ideal but gets the job done).
There are about 20 columns which are all Text fields or char fields.
I also noticed that doing a SELECT * FROM table WHERE id = 'XXX' is very slow...
The MySQL server is running on a Laptop which has an Intel Centrino 2GHZ with 512MB RAM and has been installed with the default settings.
I have also tried this with the MS SQL Server Mobile (I installed the older SQL Everywhere based on an article I read on this excellent site) and I get similar results with the speed of the SELECT and UPDATES.
INSERT is also quite slow after about 2000 rows have been added to the database.
I would appreciate any help or advice.
Thanking you in advanced.
Paul

How many indexes are on the table that you are inserting into? How many of them are clustered? If you insert large amounts of data into a table with clustered indexes, then everytime you do the insert information needs to be moved around.
One approach is to drop the indexes, insert the data and then recreate the indexes. The index creation only happens once (instead of 20,000 times) and is far more efficient.

Ok thanks for your reply. I will give this a try and will look up what clustered and non-clustered means.
I am a bit of a newcomer to SQL programming so I am on that learning curve right now....
Once I have found an improvement I will post my findings...
Do you think that my hardware, 2GHz Centrino Laptop with 512MB is sufficient. I understand that you can never have enough memory and will upgrade this soon... but it is not like my DB is Gigs of data!

I would have thought that the spec of your hardware was enough for testing purposes.

Hi,
Say if all database on the server has the same structure, how do i query all of the databases available on the server? Can i do it in one single SQL query ?
The normal way to do this is to use multiple database selections. but this is too tedious (e.g: SELECT <column>.<db1> FROM <db1>,<db2>,... GROUP BY <column>.<db1> ORDER BY <column1> DESC). What happens if i have more then 30 databases of the same structure ?
Can anyone help me ?
Cheers
