Booleans tend to get stored in bit columns. 0=false, 1=true. If you are using parameterised queries then you can sent it a Boolean and it will do the conversion for you.

Best way of searching XML [modified]

I have a system which uses dynamic forms generated from XML, it saves the results in XML to a seperate table and combines the two on reload but I need a fast way of searching the XML and looking for suggestions, the data is stored like this:

<field name="<fieldname>" value="<somevalue>">

I was thinking of using something like:

SELECT * FROM xmldatatable WHERE xmldata LIKE 'value="%<searchterm>%"';

Would this be acceptable? I would imagine it would start to get very slow once the record numbers start increasing?

Inserting a Row - Returning the ID

Hi There

This has got to be an easy one... I am coming to ADO.NET from an ADO background, so i appologise if it comes across as totally stupid!

All i want to do is insert a new row into a table and pull back the autonumber primary key assigned to it.

What i don't want to have to do is:

1) Fill a Dataset in order to get a DataTable definition.
2) Use stored procedures.

Anybody know the answer off the top of their head? Guess i really need to buy a good ADO.NET book.

Thanks In Advance
Rich

You don't need to know the name to put the results into a dataset. Just look at the overloads available.

In SQL Server: What is "ntext"? What is it for? How to use?
It is difficult for me to understand. A example will help me better.

For example: I have a Web page. I need display the content of news,include texts that larger than data type of ntext for a column.

What must I do now?

Thanks!

From bol

ntext: Variable-length Unicode data with a maximum length of 2^(30 - 1)(1,073,741,823) characters. Storage size, in bytes, is two times the number of characters entered. The SQL-92 synonym for ntext is national text.

If your news content will always be less than 8000 characters you can use varchar or nvarchar. Otherwise you will have to use text, ntext or image datatype.

I am trying to creat a function in SQL Server where it returns a the value of a column in a table where the column is passed as a parameter.

Below is the function where I want to return the value in the user table for column @field. Thanks for your help.

CREATE FUNCTION [dbo].[USER_RETURNCOLUMN] (@userid decimal, @field varchar(200))
RETURNS varchar(2000)
AS
BEGIN

DECLARE @RETURNVALUE varchar(100)

SELECT @RETURNVALUE = ''

SELECT @RETURNVALUE = @field
FROM USER_TABLE
WHERE USER_ID = @userid

RETURN @RETURNVALUE
END

If you ask me no chance to do this in a user defined function. You would need dynamic SQL with exec( @stmt ) and that is not allowed in UDFs. Can't you use a stored proc? You can use dynamic SQL there.

Rainer.

i want to sort a table by string column

this column contains data in this format ddd/dddd (ex: 100/2006 or 6/2006)
so when i order the table by this column, it will sort like this:
1/2006
11/2006
111/2006
2/2006
22/2006

but i want to sort like this
1/2006
2/2006
11/2006
22/2006
111/2006

so, is there any why to sort like this on a vb.net application not in the database?

You have trusted_connection = true and yet you are not wanting to use a trusted connection as you supply a user name and password. As trusted connections are considered more secure it tries to log you on using a trusted connection, but it fails.

Hi
I need to modify the excel export feature in Reporting Services... The issue is that client needs to have chart in excel format after exporting so that user can manually change the values in excel sheet to check the effect in the chart dynamically. Can anybody tell me how I can do that? I know it would require the creation of chart in BIFF format. But could not find out how?

If someone knows any .NET library that can help me in that please let me know. I don't want to go for SoftArtisian Office Writer as it has certain limitation as it doesn't supports the grouping of data in RS.

Thanks

SQLite for small software

16-Jun-06 19:18

I'm considerind adding database capabilities to my software. First step is selecting the proper database. The database should have 0 maintenance, be light weight. I would also appreciate a single file binary database and not BDF/Paradox like ASCII files.
At the moment I think SQLite could make it.

Once you made a choice - especially with small companies like mine - it is difficult to switch to another one. So since I'm not a database specialist, I would appreciate advices or suggestions on other candidates, and possibly pros and cons.

Thanks,
