Hi,
Problem:
I'm using C# 2005. The data type of the bitmap file saved to database is "long binary data". It should be "OLE Object".
Source Code:
Bitmap myBitmap = new Bitmap(@"c:\Picture1.bmp");<br />
OleDbConnection conn = new OleDbConnection("<<My Connection String>>");<br />
conn.Open();<br />
string sql = "UPDATE Table1 SET fldOLE = @fldOLE WHERE fldID = 5";<br />
OleDbCommand command = new OleDbCommand(sql, conn);<br />
command.Parameters.Add(new OleDbParameter("@fldOLE", myBitmap));<br />
int rowsAffected = command.ExecuteNonQuery();
Question:
How can I save Bitmap to database with data type "OLE Object"?
Thanks in advance

Hi All,
I am trying to get a file from an Ftp and Copy data (*csv file) on to one of my tables in SQL 2005 database.
I am not sure but SQL server 2005 integration service has a way to create a package that allows me to do this task.
Can any one tell me how to go about it?
your ideas are much appreciated.
Thank you

Use the FTP task to copy the file to an accessable directory, then you can create a data flow task which uses a flat file source, processes the file and then puts the data in the appropriate data flow destination.
Your package designer should resemble this:
<br />
FTP Task --> Data Flow Task<br />
Open the Data flow task (double-click) and it should resemble this:
<br />
Flat File Source --> [intermediate transformations you may need (if any)] --> Sql Server Destination<br />
Just drag the items mentioned to the designer surface, open each item and set the properties needed.

Hi,
Can I total a detail column at group level on reprting services. I can see how I would put a footer in and total from the SQL but I need things totalling down the page at a smaller level.
e.g.
Sales
Product Type
House Product Uk Sales India Sales
DVD 6 10
Oven 7 12
Total 13 22
Garden Trees 10 15
Fences 34 10
Total 44 25
Any help welcome !
Thanks in advance

Hi
i am creating dataTable at runtime and binding rows at runtime . how to insert the all the rows in dataTable to database
|
|
|
|
|
Create a Command object which defines the INSERT command then create a DataAdapter object and assign your Command object to the adapter's Insert command. Make sure when you define the data table object to map the datatable's column names to the parameter objects in the insert command you created.

the code in my application is:
OleDbCommand com = new OleDbCommand();
com.Connection = con;
com.CommandText = "UPDATE tblUsers SET Password=? WHERE UserName=?";
com.Parameters.Add("UserName", OleDbType.WChar);
com.Parameters.Add("Password", OleDbType.WChar);
com.Parameters["UserName"].Value = this.UserName;
com.Parameters["Password"].Value = this.txtPassword1.Text;
-------------------------------------------------------------------------------
When I run the application , it gives the syntax error in update query.
I am unable to find where I am going wrong
Kindly help me!

Why not you try this:
com.CommandText = "UPDATE tblUsers SET Password='" + this.UserName.Text + "' WHERE UserName='" + this.txtPassword1.Text + "'"
Do good and have good.

Shouldn't that be:
com.CommandText = "UPDATE tblUsers SET Password='" + this.txtPassword1.Text + "' WHERE UserName='" + this.UserName.Text + "'"

There are two major flaws in your code:
1. Generating SQL statements on the fly is generally considered bad practice. It leaves you exposed to SQL injection attacks. Instead, consider writing a stored procedure to perform your update and call it from your .NET code.
2. You appear to be storing your user's passwords in clear text. This is very insecure. You should consider encrypting your password using a 1-way salted hash algorithm.

try this code
OleDbCommand com = new OleDbCommand();
com.Connection = con;
com.CommandText = "UPDATE tblUsers SET Password=? WHERE UserName=?";
com.Parameters.Add("UserName", OleDbType.WChar);
com.Parameters.Add("Password", OleDbType.WChar);
com.Parameters["UserName"].Value = this.UserName.Text;//Error was here
com.Parameters["Password"].Value = this.txtPassword1.Text;
|
|
|
|

try this
com.CommandText = "UPDATE tblUsers SET [Password]='" + this.txtPassword1.Text + "' WHERE [UserName]='" + this.UserName.Text + "'"

No. Don't do this. Haven't you heard of SQL Injection Attacks? Have a read through the many wonderful articles before you find out why this is wrong, oh so wrong.

Sure I have attention about SQL injection attacks...

If you are aware about SQL Injection Attacks, then why do you recommend something that is wide open to such an attack? It's your responsibility when posting an answer to give good advice and not to post something that is such blatant bad practice.
|
|
|
|
|
but it's not my responsibility to teach others about SQL injection all of programmers must know about SQL injections...
Why you not gonna explain him about SQL injections?

Hi,
I have a database called MyDatabase and I am looking to create another datebase called MyDatabase_Dev with the exact same tables and data in it, I want no primary keys that are lost and no auto numbering that it not set.
I can't remember how to do this. I tried Import data on the MyDatabase_Dev, but I loose primary keys and auto numbering. I am using SQL Server 2005.
Thanks
Brendan

Backup your database, then restore it under a different name.

I tried that but it gave me an error. But then I tried it again and saw that I did not change the destination file name to my new name, and then it worked.
Thanks

Just another quick question about the database restore. After the new database is restored, I right clicked on the database and clicked on properties. I then clicked on the files tab, and to the right there is a column with a name called "Logical Name". And the logical name is still MyDatabase, the original database that I did the backup from. Wasn't this supposed to have changed when I changed the file names when I did the restore? I don't want it to have an relationship the original database, I want it to be on it's own. I hope you understand.

You can just change this on the file tab if you want to. The physical names of the database files should be different from the original database and follow the name of your new database. The database you have restored from the backup doesn't have any relationship with your original database, so you don't need to worry about this.
