Hi,
I have a StreamReader object that I initialized with a stream, now I want to save this stream to disk (the stream may be a gif or jpg or pdf etc).
SO my code so far is:
StreamReader sr = new StreamReader(myOtherObject.InputStream);
I need to save this to disk (I have the filename).
In the future I may want to store this to sqlserver
I have the encoding type also, which I will need if I store it to sql server right?
i am trying to create a statement in sql (for a table which holds stock symbols and price on specified date) with avg of 5 day price and avg of 15 days price for each symbol.
table description:
symbol
open
high
close
date
the average price is calculated from last 5 days and last 15 days. i tried this for getting 1 symbol:
SELECT avg(close),
avg(`trd_qty`)
FROM (select *
from cashmarket
WHERE symbol = \'hdil\'
order by `M_day` desc
limit 0,15 ) s
...but I couldn't get the desired the list for showing avg values for all symbols.
I want to query like this:
select * from table where concat(',', ServiceCodes, ',') like '%,33,%';
select * from table where (','||ServiceCodes||',') like '%,33,%';
so, I wrote this code:
ICriteria cri = NHibernateSessionReader.CreateCriteria(typeof(ConfigTemplateList));
cri.Add(Restrictions.Like(Projections.SqlFunction("concat", NHibernateUtil.String, Projections.Property("ServiceCodes")), "%,33,%"));
I get sql similar :
select * from table where (ServiceCodes) like '%,33,%';
But it is not what I want,how to do it???
thanks!
So this my first question here, let's look how it works.
I'm working on a project, which has to to provide a "Native XML WebService" on a SQL Server 2005. The web service and the WSDL generation works fine. But there are troubles with the authentication.
Is it possible to turn the authentication off (The tests and the documentation by Microsoft say no.)?
And if so how?
I have a large table (300 million lines) that I would like to dump to a csv - I need to do some processing that cannot be done with SQL. Right now I am using Squirrel as a client, and it does not apparently deal very well with large datasets - at least as far as I can tell from my own (limited) experience. If I run the query on the actual host, will it use less memory? Thanks for any help.
I have test_scores table with following fields:
Table schema:
id (number)
score1 (number)
score2 (number)
score3 (number)
score4 (number)
Sample data:
id score1 score2 score3 score4
1 10 05 30 50
2 05 15 10 00
3 25 10 05 15
Expected result set:
id col_name col_value
1 score4 50
2 score2 15
3 score1 25
What is a good SQL for this?(I am using MySQL.)
Hi folks,
I've started using try catch blocks (bit late i know!) but now im not sure what to do with the exception once i've caught it. What do people usually do here?
-- Jonesy
Try
connection.Open()
Dim sqlCmd As New SqlCommand("do some SQL", connection)
Dim sqlDa As New SqlDataAdapter(sqlCmd)
sqlDa.Fill(dt)
Catch ex As SQLException
' ahhhh what to do now!!!?
Finally
connection.Close()
End Try
I have the following SQL query which returns the correct results:
SELECT *
FROM `tags`
WHERE tag_name = '???\\\"?-???????'
If I change it to
SELECT *
FROM `tags`
WHERE tag_name LIKE '???\\\"?-???????'
or to
SELECT *
FROM `tags`
WHERE tag_name LIKE '???\\\"?-???????%'
It doesn't work. It will work if I remove all the backslashes and " from the query.
I have a asp:GridView with a HyperLinkField. It's DataNavigateUrlFormatString property is set to View.aspx?id={0}&isTechnical={1}
Select command of appropriate SqlDataSource returns columns of type INT and BYTE (from SQL Server 2008).
So displayed string becomes something like View.aspx?id=1&isTechnical=1. But I want to display isTechnical=true|False, i.e. Convert.ToBoolean(row["isTechnical"]).ToString().ToLowerInvariant().
How to implement such conversion in page markup?
I have a table created long ago in postgreSQL. Now i want to look at the sql statement used to create it but cannot figure it out.
Also when i do the \dS+ tablename it says table not found, but \dt+ tablename is working fine. The \dS+ lists all the table names owned by the root postgres user and doesn't show up tables that i created with my user account.
Any help is greatly appreciated.
Thanks

Hi,
Is there any way to cache LINQ to SQL queries by looking at the parameters that were previously passed and bypass the database all together?
I know L2S caches some database calls, but I'm looking for a permanant solution as in, even if the applciation restarts, that cache reloads and never asks the database again.
Are there any frameworks for C#?
This is probably easy, but eludes me.

I have tried using Group By and HAVING COUNT(*)0 all with the same wrong results
We have a requirement to log IP address information of all users who use a certain web application based on JEE 5. What would be an appropriate sql data type for storing IPv4 or IPv6 addressses in the following supported databases (h2, mysql, oracle). There is also a need to filter activity from certain IP addresses. Should I just treat the representation as a string field (say varchar(32) to hold ipv4, ipv6 addresses)
If I try this statement:
INSERT INTO TerminalEventChild (id,stringValue) VALUES
(64,'version123|');
MySQL fail with :
Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''version123' at line 1
SQLState: 42000
ErrorCode: 1064
If I remove the | character, everything works fine. Any idea?
