Everywhere its said not to use image /BLOB data types. But when the database have those columns and which is unavoidable then what we can do. I need to replicate a table and this table take 5hrs.. to replicate. Can you suggest how to increase the performance for replicate this table.

Thanks in advance.

how to retrieve it in sql command prompt?

example:
Table1 save to File-Group1 And File-Group1 Save in Drive C
Table2 save to File-Group2 And File-Group2 Save in Drive D Of Hard Disc2

Today’s if someone say: ” it’s not correct to save the images to the database because the database will huge ” Like someone say : ” it’s Not correct to save the images to the Hard Disc!”

//– you need to have a FileUpload control in your page to upload the images –//

string myFileName = FileUpload1.PostedFile.FileName;
string copy = Path.GetFileName(myFileName);

try
{
string Upath = @”~\Images\” + copy; //– This is the server path where the images are stored–//
FileUpload1.PostedFile.SaveAs(@”C:\Images\” + copy); //– This is the same server path in file system using file path instead of root directory. This is just for an example –//

string sql = “INSERT INTO Frm_ATAC_Events (Content_Type, File_Path) VALUES (‘” + FileUpload1.PostedFile.ContentType + “‘, ‘” + Upath + “‘);”;
SqlConnection connection = ConnectionManager.GetAetnaForumDBConnection();
SqlCommand command = new SqlCommand(sql, connection);
command.CommandType = CommandType.Text;

command.ExecuteNonQuery();
}
catch (Exception ex)
{
Response.Write(ex.Message);
}

//– You can use the below code to retrieve the images back to a grid view–//
DataSet ds=new DataSet();
string sql = “SELECT FILE_PATH, CONTENT_TYPE FROM Image_Table”;
SqlConnection connection = ConnectionManager.GetAetnaForumDBConnection();
SqlCommand command = new SqlCommand(sql, connection);
command.CommandType = CommandType.Text;

SqlDataAdapter adapter = new SqlDataAdapter(command);
adapter.Fill(ds, “Images”);

GridView2.DataSource = ds.Tables[0];
GridView2.DataBind();

//— Now Bind the ImageUrl in the gridview to the File_path field using the code ‘Eavl(“File_Path”)’.–//

This should work very well…

You may want to write to a temporary file and rename the file on successful transaction.

Moreover, optimizations to database design and query style can be more helpful.

As suggested above you can use another table to store the images, and retrieve the image only when necessary. Thereby, reducing the load on database server.

I only want this single question answered please.

Could you store directory path in a string variable and display that value in the browser through any other webcontrols or directly? If yes please show me how did you do it?

We have a SAN with combonation SATA and FC-drives.
Can I still store the binary\photo files onto the SATA (15k) drives with HBA(4gb) and get good performance on the reads and writes? Very curious about this one? The system will produce fast transaction from mobile pda’s and about 6000 users will update within about 3hr period. Any other performance recommendation will be greatly appreciated. I have already sepreate all data files on seperat arrrays and give tempdb 6 fix length files.

Please comment at will.

The insert/update/select is by no means “massive” as the author says. You would have a memberid or some other indexed cilumn in which you are using to grab the row.

I think it is much nicer to not have to worry about a file server. The performance hit is marginal it is definately worth doing.

Plus it also allows you to stop using cffile and you cna use cfimage tags and functions to alter image to a blob and pas sit to your stored proc.

Its a win win all the way around really. I own a dating site with over 100k members and store all profile pictures in the DB. Each member can have up to 200 photos. When I display the gallery I do a next n and only show 10 at a time.

Also never finish the sentence “In my case all images..”

should say “In my case all images are probably less than 50k each.
