Don't store files in the database if not absolutely required. It will put a large load on the database server and the network. If it is a web app, it can also tie up valuable threads for extended periods and cause delays for users.
If you must do it, store the file in text, ntext, or image field types. To store the file use a TEXTPTR and the UPDATETEXT commands. If you google on these, you will find some examples.

Hello!
I would like some help with the following:
I want to get one (1) result out of two columns. I have for example "user1" and "user2". I would like to have "user1" as the result if "user2" contains the word "flintstone" and I would like to have "user2" as the result if "user1" contains the word "flintstone". I would like either of these to merge into a common name such as "user" or something, that I can use further with ASP.NET DataRepeater. Hope you understand, I have a sketch as well:
SELECT user1 FROM table WHERE user2='flintstone' --\
>-- user
SELECT user2 FROM table WHERE user1='flintstone' --/
Thank you!

Hallo,
I just posted this message in C#-section, but I saw the ADO.NET section and I think its better to post it here... sorry for doubleposting...
I'm a real beginner with C# and I have a silly problem with one DataTable combined with a DataGrid.
Short describing of surround:
I have one DataSet with three DataTables, each shown in DataGrids.
The DataSet is persistent (typed DataSet) as .xsd-file.
DataBase ist MSDE. All three DataTables are filled with the
DataAdapter.(DataSet, DataTable).Fill-Method.
If I execute the fill-Methode for one table twice or more, in my datagrid the records are added. To avoid this behaviour, I want to use the
DataSet.Tables["table"].Clear()-Method
before executing the Fill-Method. With two DataTables it works, but with the third, the DataGrid stays empty after the Fill-Method.
- in the debugger I can see that there are records in the DataTable
- when I click into the DataGrid, an error occurs that I try to translate (German version):
"DataBinding could not find line in list that can be used vor all bindings."
Help would be very appreciated.
Thanks

If i have 2 table, table1 and table2, and joining them in a view, should I first select all fields from table1 and then fields from table2, or I can select in random order from both tables? Is there any performance issue, if selecting in random order? Thanks.

It is certainly possible to build a dynamic SQL query like the one you are referring, but I think you have just got your string formation messed up.
Assuming that SearchBox and TextBox4 are VB textboxes containing some textual criteria, then try:
<br />
strsql = "SELECT * FROM dic WHERE english='" & SearchBox.Text & "' OR '" & TextBox4.Text & "'"<br />
Notice the ' in the string separators.
This would form a valid statement e.g.
SELECT * FROM dic WHERE english='AMERICAN' OR 'CANADIAN'
I Dream of Absolute Zero

I want to pull data from a table using a regular SQL statement for my adapter (using WHERE and ORDER BY - this I can do fine) but I want to use values from another table as criteria for my WHERE statements... how do I do this?
Basic Sample would be nice.
Thanks

There are many ways. Can you give an example of what you are trying to do? Do you just want to use the value from one row in the other table as the criteria? (Simply extracting the data into variables then using in a where might be sufficient in this case) Do you want to use data from many rows as the criteria? (In which case some sort of table join would be best)

Lets say Table1 has:
ID, Num1, Num2, Num3, FullName, ItemName, ItemColor, ItemValue, ItemWeight
Table2 has:
ID, Ber1, Ber2, Ber3
To sort Table1 generically I would use:
SELECT ID, Num1, Num2, Num3, FullName, ItemName, ItemColor, ItemValue, ItemWeight FROM Table1 WHERE ItemValue>100 ORDER BY Num1, Num2, Num3, ItemWeight
I would like to use Table2’s values from columns Ber1, Ber2, and Ber3 as criteria to sort by for Table1’s Num1, Num2, and Num3’s values.
Just the values from a single row for now would be helpful (Columns Ber1, Ber2, and Ber3).
This is used for configuring the Adapter for the connection.
By the way, the two tables aren't related.
The columns (Num1, Num2, Num3 and Ber1, Ber2, Ber3) do have the same Look-Up Tables. I just have Table2 as a criteria to sort Table1 by.
Looking into JOINS.
Thanks

Thanks Colin,
I ended up using an INNER JOIN similar to what follows:
SELECT * FROM Table1 INNER JOIN Table2 ON Table1.Num1 = Table2.Ber1 AND Table1.Num2 = Table2.Ber2 AND Table1.Num3 = Table2.Ber3 WHERE ItemValue > 100 ORDER BY ItemWeight, AndAnythingElse
This was the easiest, just didn't know what was best.

Anybody know if the COALESCE(NULLIF ...)...) can raise error itself, and if
it safely to use this combination of checking error status
Every time after i calling to some store procedure i use this:
------------------------------------------
DECLARE @intError int
EXEC @intError = myProcedure @param1, @param2 .....
SELECT @intError = COALESCE(NULLIF(@intError, 0), @@ERROR)
IF(@intError =0 )
......
......
--------------------------------------------
my question is, can the @@ERROR variable have an error that COALESCE or
NULLIF function were raise?
Thanks.
P.S. if it's not good idea to use it after calling to stored procedures so
what can u advice me
