SQL Server 2014 :: How To Return Bitmap Image From Custom Assembly To SSRS Report
Dec 11, 2013I am using the QRCode4CS class [URL] .... to generate QR codes.
I can use the following code to successfully return a bitmap image to a picturebox in a Windows Form Application.
public class CreateQRCodeClass
{
public static Image CreateQRCodeImage(string inputString)
{
QRCode4CS.QRCode qrcode = new QRCode4CS.QRCode(new QRCode4CS.Options(inputString));
qrcode.Make();
[Code] ....
In trying to adapt the same code (below) to display a QR code in an SSRS report I get the error "There is an error on line 1 of custom code: [BC30311] Value of type 'System.Drawing.Image' cannot be converted to '1-dimensional array of Byte.'
Here is the custom code I am using.
Public Function QRCode(ByVal RetailerId As String) as Byte()
Return QRCode4CSCreateQRCode.CreateQRCodeClass.CreateQRCodeImage(RetailerId)
End Function
Here is the revised custom assembly.
public class CreateQRCodeClass
{
public static byte[] CreateQRCodeImage(string inputString)
{
QRCode4CS.QRCode qrcode = new QRCode4CS.QRCode(new QRCode4CS.Options(inputString));
qrcode.Make();
Image canvas = new Bitmap(86, 86);
[Code] ....
What data type can I successfully return to SSRS to display the image?

May 4, 2007Hello,
I have not seen a response to this specific question so here goes. I had working code for loading an image into my smart device SQLCE db and for retrieving images. But after upgrading my application to SQLCE 2.0 I am unable to use my retrieve code. This is what was previously working,

Dim ImageStream As New System.IO.MemoryStream(ImageBytes)

This is what I successfully use to save the image to the database
Dim PictureInfo As New FileInfo("My DocumentsUSAFlag.bmp") 'OpenDialog.FileName
Dim PictureSize(PictureInfo.Length) As Byte
If PictureSize.GetValue(0) <= 69 Then
Dim fsPicture As New FileStream(PictureInfo.FullName, FileMode.Open)
Dim PictureReader As New BinaryReader(fsPicture)
PictureReader.Read(PictureSize, 0, PictureSize.Length)
'find the previous record and add the picture
rs.SetValue(rs.GetOrdinal("OLE"), PictureSize) 'could be FlashcardAPic
rs.SetValue(rs.GetOrdinal("Picture"), "True")
rs.Update()

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:
Code Snippet
Bitmap myBitmap = new Bitmap(@"c:Picture1.bmp");
OleDbConnection conn = new OleDbConnection("<<My Connection String>>");
conn.Open();
string sql = "UPDATE Table1 SET fldOLE = @fldOLE WHERE fldID = 5";
OleDbCommand command = new OleDbCommand(sql, conn);
command.Parameters.Add(new OleDbParameter("@fldOLE", myBitmap));
int rowsAffected = command.ExecuteNonQuery();
Question:
How can I save Bitmap to database with data type "OLE Object"?

View 1 Replies View RelatedHuge Tables: Minimizing Row Size - Remove Null Bitmap
Apr 21, 2007I am in the process of designing a SQL 2005 database with tables that may hold several hundreds of millions of rows.
Due to various constraints, I am trying to save as much space as possible by optimizing the size of a row. Currently one row contains the following columns:
byte(4), byte(3), byte(3) = 10 bytes.
Adding 4 bytes for the row header, plus 3 bytes for the null bitmap (as described in BOL) I am ending up with 17 bytes/row. In a real world test it was an average of 18.3 bytes/row.
There are no indexes, no primary key and all columns are not NULL. Hence my question: since no column allows a null value, is there a possibility to "remove" the 3 bytes Null Bitmap?
Is there any other way to shave off one or two more bytes by using a clustered index etc?
Thanks

SQL 2012 :: Full Text Index How To Make It NOT To Index Embedded Or Attached Documents
Sep 30, 2015I am using Full Text Index to index emails stored in BLOB column in a table. Index process parses stored emails, and, if there is one or more files attached to the email these documents get indexed too. In result when I'm querying the full text index for a word or phrase I am getting reference to the email containing the word of phrase if interest if the word was used in the email body OR if it was used in any document attached to the email.
How to distinguish in a Full Text query that the result came from an embedded document rather than from "main" document? Or if that's not possible how to disable indexing of embedded documents?
My goal is either to give a user an option if he or she wants to search emails (email bodies only) OR emails AND documents attached to them, or at least clearly indicate in the returned result the real source where the word or phrase has been found.
Clustered Index On Client_ID+ORderNO+OrdersubNo, If I Create 3 Noncluster Index On Said Column Will It Imporve Performance
Dec 5, 2007
Dear All.
We had Teradata 4700 SMP. We have moved data from TD to MS_SQL SERVER 2003. records are 19.65 Millions.
table is >> Order_Dtl
Columns are:-
Client_ID varchar 10
Order_ID varchar 50
Order_Sub_ID decimal
.....
...
..
.
Pk is (ClientID+OrderId+OrderSubID)
Web Base application or PDA devices use to initiate the order from all over the country. The issue is this table is not Partioned but good HP with 30 GB RAM is installed. this is main table that receive 18,0000 hits or more. All brokers and users are using this table to see the status of their order.
The always search by OrderID, or ClientID or order_SubNo, or enter any two like (Client_ID+Order_Sub_ID) or any combination.
Query takes to much time when ever server receive more querys. some orther indexes are also created on the same table like (OrderDate, OrdCreate Date and Status)
My Question are:-
Q1. IF Person "A" query to DB on Client_ID, then what Index will use ? (If any one do Query on any two combination like Client_ID+Order_ID, So what index will be uesd.? How does MS-SQL SERVER deal with these kind of issues.?
Q2. If i create 3 more indexes on ClientID, ORderID and OrdersubID. will this improve the performance of query.if person "A" search record on orderNo so what index will be used. (Mind it their would be 3 seprate indexes for Each PK columns) and composite-Clustered index is also available.?
Q3. I want to check what indexes has been used? on what search?
Q4. How can i check what table was populated when, or last date of update (DML)?
My Limitation is i Dont Create a Partioned table. I dont have permission to do it.
In Teradata we had more than 4 tb record of CRM data with no issue. i am not new baby in db line but not expert in sql server 2003.
I am thank u to all who read or reply.

The Index Entry For Row ID Was Not Found In Index ID 3, Of Table 357576312
Jul 9, 2004Hi,
I'm running a merge replication on a sql2k machine to 6 sql2k subscribers.
Since a few day's only one of the merge agents fail's with the following error:
The merge process could not retrieve generation information at the 'Subscriber'.
The index entry for row ID was not found in index ID 3, of table 357576312, in database 'PBB006'.
All DBCC CHECKDB command's return 0 errors :confused:
I'm not sure if the table that's referred to in the message is on the distribution side or the subscribers side? A select * from sysobjects where id=357576312 gives different results on both sides . .
Any ideas as to what is causing this error?
Advantages Of Using Nonclustered Index After Using Clustered Index On One Table
Jul 3, 2006Hi everyone,
When we create a clustered index firstly, and then is it advantageous to create another index which is nonclustered ??
In my opinion, yes it is. Because, since we use clustered index first, our rows are sorted and so while using nonclustered index on this data file, finding adress of the record on this sorted data is really easier than finding adress of the record on unsorted data, is not it ??
Thanks
SQL 2012 :: Clustered Index Key Order In NC Index
Mar 5, 2015I have a clustered index that consists of 3 int columns in this order: DateKey, LocationKey, ItemKey (there are many other columns in this data warehouse table such as quantities, prices, etc.).
Now I want to add a non-clustered index on just one of the other columns, say LocationKey, like this:
CREATE INDEX IX_test on TableName (LocationKey)
I understand that the clustered index keys will also be added as key columns to any NC indexes. So, in this case the NC index will also get the other two columns from the clustered index added as key columns. But, in what order will they be added?
Will the resulting index keys on this new NC index effectively be:
LocationKey, DateKey, ItemKey
OR
LocationKey, ItemKey, DateKey
Do the clustering keys get added to a NC index in the same order as they are defined in the clustered index?
Clustered Index Vs. Full Text Index
Jun 18, 2008Quick question about the primary purpose of Full Text Index vs. Clustered Index.
The Full Text Index has the purpose of being accessible outside of the database so users can query the tables and columns it needs while being linked to other databases and tables within the SQL Server instance.
Is the Full Text Index similar to the global variable in programming where the scope lies outside of the tables and database itself?
I understand the clustered index is created for each table and most likely accessed within the user schema who have access to the database.
Is this correct?
I am kind of confused on why you would use full text index as opposed to clustered index.
Thank you

Index/performance Index For SELECT.... IN Statement
Sep 10, 2007
Hi All,
I 'm working to improve some sql performance.
One of the major syntax inside the SELECT statment is ..
WHERE FIELDA IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='A') AND
WHERE FIELDB IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='B') AND
WHERE FIELDC IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='C') AND
WHERE FIELDD IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='D') AND
WHERE FIELDE IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='E') AND
WHERE FIELDF IN (SELECT PARAVALUE FROM PARATABLE WHERE SESSIONID = "XXXXX" AND PARATYPE='F')
(It's to compare the field content with some user input parameter inside a parameter table... )
I think properly is that the SELECT ... IN is causing much slowness in the sql statement. I have indexed FIELDA , FIELDB, FILEDC etc and those PARAVALUE and PARATYPE in the PARATABLE table. But perfromance is still slow and execution takes >20 seconds for 200000 rows of records.
Do any one know if still any chance to improvide the performance like this?
Much Thanks,
Andy

How To Extract Data From SQL Server With The Index Server Search Result?
Jan 14, 2006I am developing a Recruitment Agency WebsiteI am using MS SQL Server in which I have a table called CV_Details which stores all the details of different Job Seekers. I have stored all the Word and PDF docs of the Job seekers in a 'mycatalog' using Index Server and stored the path in the CV_Details table along with rest of the cv details. Basically I want to download the cv's which i get after making a search in the doc's. I am able to get the filename, Path, Filesize by using Index Server Query.Is it anyway possible to extract all the CV Details data by matching the path.I want the cv details from the SQL Server of all the Related Paths at the same time not one at a time. Is it possible.I tried alot but i'm going nowhere. I'm giving my code below. Can anyone help me please.Thank you very much in Advance
string strCatalog = "TestCatalog", strsearchstrings=""; string strQuery=""; strsearchstrings = txtsearch.Text;
strQuery = "Select Filename,PATH from Scope() where FREETEXT('" +strsearchstrings+ "')"; // TextBox1.Text is the word that you type in the text box to query by using Indexing Service. string connstring = "Provider=MSIDXS.1;Integrated Security .='';Data Source="+strCatalog;

Index Server The Only/best Way?
Aug 18, 2006I've done a search on this topic and came up with several posts, none helping me too much.
Basically, I"m not searching the contents of my website but rather records in a product table. And I want the users to be able to put
something generic as half a movie title or product name.
And so, I want to know if either there's a way to optimize searching tables with the LIKE clause etc. or if it just really comes down to using teh Index Server.
But if there are other implementations or methods out there would someone please let me know? Thanks.

SQL Server Won't Use My Index
Apr 10, 2001Hello,
I have a very simple query:
select count(*) from MyTable where MyDate > '4/7/2001' and MyField = 'y'
I have an index on MyDate. If I run the query without the check on MyField, it uses the index. If I add the criteria that MyField = 'y' the query no longer uses that index and does a clustered index scan (the clustered index is on an identity column - not my choice).
If I use the WITH clause and force it to use the index, performance is drastically improved, but I would REALLY rather not have to force index usage. I've tried running UPDATE STATISTICS, but that didn't help.
It looks like using the indexes causes more reads, but it takes 1/15th of the time (I tested this both with and without caching of the data).
Any ideas on what's going on or how to fix this?
Thanks,
-Tom.
Index SQL Server

View 1 Replies View RelatedIndex Scan Vs Index Seek
Mar 1, 2004I have a really strange problem.
I execute this query:
declare @cid int
set @cid = 2003227
select * from sales s, product p where p.product_Id = s.product_Id and customer_id = @cid
select * from sales s, product p where p.product_Id = s.product_Id and customer_id = @cid or @cid = 0
3 Million rows in sales, 120000 in product.
The first does and index seek, the second an index scan.
The execution plan reports that the scan takes 99.87% of the cost, and the seek takes 0.13%
This problem obviously gets worse the bigger the dataset / query /etc.
The reason I query this, is because it never used to take this long to do index scans. Is there something i can change, something i can fix?
Any help would be appreciated.
