I have XSD schema file i want to create sql server table using xsd file.
In c# console application there is any solution? please provide me.
I have searched several sites but don't get any perfect solution for that please help me.
This is the code I'm using
public void BulkLoadData() {
SQLXMLBULKLOADLib.SQLXMLBulkLoad loader = new SQLXMLBULKLOADLib.SQLXMLBulkLoad();
loader.ConnectionString = "Data Source=.;Initial Catalog=SourceDB;Integrated Security=True";
loader.SchemaGen = true;
loader.SGDropTables = true;
loader.BulkLoad = false;
loader.Execute(
"C:\\pk\\PPMapSchema.xsd",
"C:\\pk\\XML_ContractTypesCombined.xml");
}
}
The error I get is
Connection string not found

I'm trying to automate the creation of an exact copy of an Analysis Services database using Microsoft.AnalysisServices namespace. My code is:
using (var server = new Server())
{
server.Connect(connString);
var newDb = server.Databases.GetByName(dbName).Clone();
newDb.Name = newDbName;
newDb.ID = server.Databases.GetNewID();
server.Databases.Add(newDb);
newDb.Update(UpdateOptions.ExpandFull);
server.Disconnect();
}
However it seems it creates an empty database instead because from SSMS i'm not able to see any tables, datasources and similar (check my screenshot here).
Is there a way to fix this? Thanks.

You need to clone the child Model object using Model.clone() method as well to make to make it work. You can add Model using code like below -
var connString = "Provider=MSOLAP;Data Source=asazure://westus2.asazure.windows.net/xxxxxxxxxxxx:rw";
var dbName = "AW Internet Sales";
var newDbName = "CloneDb";
using (var server = new Server())
{
server.Connect(connString);
var newDb = server.Databases.GetByName(dbName).Clone();
var newModel = server.Databases.GetByName(dbName).Model.Clone();
newDb.Name = newDbName;
newDb.ID = server.Databases.GetNewID();
newDb.Model = newModel;
server.Databases.Add(newDb);
newDb.Update(UpdateOptions.ExpandFull);
server.Disconnect();
}
Please find below the screenshot after the code run.
Please let me know if you have any questions.
Thanks.
I have researched on how to export BLOBs to image. A DB has an IMAGE column storing several thousand images. I thought of exporting the table but I get a BLOB file error in EMS SQL Manager for InterBase and Firebird.
There have been good posts, but I have still not been able to succeed.
SQL scripts to insert File to BLOB field and export BLOB to File
This example has appeared on numerous pages, including Microsoft's site. I am using INTERBASE (Firebird). I have not found anything related to enabling xp_shell for Firebird, or EMS SQL Manager for InterBase and Firebird (which I have also installed). My guess is: its not possible. I also tried Installing SQL Server Express, SQL Server 2008, and SQL Server 2012. I am at a dead end without having even connected to the server. The reason being I have not managed to start the server. Followed the guide at technet.microsoft: How to: Start SQL Server Agent but there are no services on the right pane to me.
PHP file to download entire column (may not post link due to rep limitation).
It has a MySQL connect section that daunts me. There on my computer is the DB as a GDB file, I also have XAMPP. I can figure out a way to use this as a localhost environment. I hope this is making sense.
Last solution is to use bcp, an idea posted on Stack Overflow titled: fastest way to export blobs from table into individual files. I read the documentation, installed it, but cannot connect to server. I use -S PC-PC -U xxx -P xxx (The server must be wrong) But the information I find all uses -T (Windows Authentication)
Summing up. I am using Firebird, as EMS SQL Manager. I try to extract all images from images table into individual files. These tools both have SQL script screens, but it appears to be in conjunction with xp shell. What would you suggest? Am I using the wrong SQL manager to accomplish this?
There are several ways:
Use isql command BLOBDUMP to write a blob to file,
Use a client library (eg Jaybird for Java, Firebird .net provider for C#) to retrieve the data,
With PHP you can use ibase_blob_get in a loop to get bytes from the blob, and write those to a file.
I don't use nor know EMS SQL Manager, so I don't know if (and how) you can export a blob with that.
The example you link to, and almost all tools you mention are for Microsoft SQL Server, not for Firebird; so it is no wonder those don't work.
Example in Java
A basic example to save blobs to disk using Java 8 (might also work on Java 7) would be:
/**
* Example to save images to disk from a Firebird database.
* <p>
* Code assumes a table with the following structure:
* <pre>
* CREATE TABLE imagestorage (
* filename VARCHAR(255),
* filedata BLOB SUB_TYPE BINARY
* );
* </pre>
* </p>
*/
public class StoreImages {
// Replace testdatabase with alias or path of database
private static final String URL = "jdbc:firebirdsql://localhost/testdatabase?charSet=utf-8";
private static final String USER = "sysdba";
private static final String PASSWORD = "masterkey";
private static final String DEFAULT_FOLDER = "D:\\Temp\\target";
private final Path targetFolder;
public StoreImages(String targetFolder) {
this.targetFolder = Paths.get(targetFolder);
}
public static void main(String[] args) throws IOException, SQLException {
final String targetFolder = args.length == 0 ? DEFAULT_FOLDER : args[0];
final StoreImages storeImages = new StoreImages(targetFolder);
storeImages.store();
}
private void store() throws IOException, SQLException {
if (!Files.isDirectory(targetFolder)) {
throw new FileNotFoundException(String.format("The folder %s does not exist", targetFolder));
}
try (
Connection connection = DriverManager.getConnection(URL, USER, PASSWORD);
Statement stmt = connection.createStatement();
ResultSet rs = stmt.executeQuery("SELECT filename, filedata FROM imagestorage")
) {
while (rs.next()) {
final Path targetFile = targetFolder.resolve(rs.getString("FILENAME"));
if (Files.exists(targetFile)) {
System.out.printf("File %s already exists%n", targetFile);
continue;
}
try (InputStream data = rs.getBinaryStream("FILEDATA")) {
Files.copy(data, targetFile);
}
}
}
}
}
Example in C#
Below is an example in C#, it is similar to the code above.
class StoreImages
{
private const string DEFAULT_FOLDER = #"D:\Temp\target";
private const string DATABASE = #"D:\Data\db\fb3\fb3testdatabase.fdb";
private const string USER = "sysdba";
private const string PASSWORD = "masterkey";
private readonly string targetFolder;
private readonly string connectionString;
public StoreImages(string targetFolder)
{
this.targetFolder = targetFolder;
connectionString = new FbConnectionStringBuilder
{
Database = DATABASE,
UserID = USER,
Password = PASSWORD
}.ToString();
}
static void Main(string[] args)
{
string targetFolder = args.Length == 0 ? DEFAULT_FOLDER : args[0];
var storeImages = new StoreImages(targetFolder);
storeImages.store();
}
private void store()
{
if (!Directory.Exists(targetFolder))
{
throw new FileNotFoundException(string.Format("The folder {0} does not exist", targetFolder), targetFolder);
}
using (var connection = new FbConnection(connectionString))
{
connection.Open();
using (var command = new FbCommand("SELECT filename, filedata FROM imagestorage", connection))
using (var reader = command.ExecuteReader())
{
while (reader.Read())
{
string targetFile = Path.Combine(targetFolder, reader["FILENAME"].ToString());
if (File.Exists(targetFile))
{
Console.WriteLine("File {0} already exists", targetFile);
continue;
}
using (var fs = new FileStream(targetFile, FileMode.Create))
{
byte[] filedata = (byte[]) reader["FILEDATA"];
fs.Write(filedata, 0, filedata.Length);
}
}
}
}
}
}
i need to create switchable web.config file which can configure N Hibernate to work with either MS-SQL Server or Oracle
I'm having 2 configuration files and one web.config files
sqlcongif.config
oracleconfig.config
if i want only SQL config i need to point to sqlconfigure.config in web.config
or else only oracle i need to point oracleconfig.config
tried with child config and other web options .
i found that similar problem when we are having connection strings in web config files
is there any options we can do this ?
thanks in advance :)
This issue could be easily solved with a switch in code (Oracle or SQL server), at the place where we ask for a ISessionFactory.
We just have to pass the config name and the connection string key:
public ISessionFactory BuildFactory(
string configFileName
string connectionStringKey)
{
// full path to the config
var fullfileName = System.IO.Path.Combine(AppDomain.CurrentDomain.BaseDirectory
, configFileName);
var document = System.Xml.Linq.XDocument.Load(fullfileName);
// NH configuration
var config = new NHibernate.Cfg.Configuration();
// feeded with all the setting in our config
using (var reader = document.CreateReader())
{
config.Configure(reader);
}
// read connection string from web.config
// ADVANTAGE: it could be even encrypted
var connectionStringFromWebConfig = ConfigurationManager
.ConnectionStrings[connectionStringKey].ConnectionString;
// use that web.config connection string
config.SetProperty("connection.connection_string", connectionStringFromWebConfig);
// create factory
NHibernate.ISessionFactory factory = config.BuildSessionFactory();
return factory;
}
And then we can call it like
var factory = BuildFactory("config/sqlconfigure.config", "sqlServerConnection")
how does one programmatically create a localdb .mdf?
acceptable solutions exclude visual studio, ssms, aspnet_regsql.
a naive stab at a solution might look like this:
static void Main(string[] args)
{
using (var con = new SqlConnection(#"Integrated Security=SSPI;Data Source=(LocalDb)\v11.0;AttachDbFilename=test.mdf"))
{
con.Open();
using (var cmd = new SqlCommand("CREATE DATABASE test", con))
{
cmd.CommandType = CommandType.Text;
cmd.ExecuteNonQuery();
}
}
}
but of course, this fails in SqlConnection.Open with the error
An attempt to attach an auto-named database for file test.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
You cannot connect to a database if the specified .mdf doesn't exist.
So... how do you create one?
Had to piece together several answers from Stackoverflow and the great Getting Started with SQL Server 2012 Express LocalDB article from #AaronBertrand
Code assumes Dapper.NET is installed:
PM> Install-Package Dapper
Programmatic creation:
var dbServerName = "SERVER_NAME";
var dbName = "DATABASE_NAME";
var infoResult = SqlLocalDbCommand($"info {dbServerName}");
var needsCreated = infoResult?.Trim().EndsWith($"\"{dbServerName}\" doesn't exist!");
if (needsCreated.GetValueOrDefault(false))
{
var createResult = SqlLocalDbCommand($"create {dbServerName} -s");
var success = createResult?.Trim().EndsWith($"\"{dbServerName}\" started.");
if (false == success)
{
var msg = $"Failed to create database:{Environment.NewLine}{createResult}"
throw new ApplicationException(msg);
}
var master = $#"Server=(localdb)\{dbServerName};Integrated Security=True;"
using (var conn = new SqlConnection(master))
{
var result = conn.Execute($"CREATE DATABASE {dbName}");
}
var #new = $#"Server=(localdb)\{dbServerName};Integrated Security=True;Database={dbName}"
using (var conn = new SqlConnection(#new))
{
//verify i can access my new database
var tables = conn.Query($"SELECT * FROM {dbName}.INFORMATION_SCHEMA.Tables");
}
}

Note that with this solution you won't see the mdf files, i'm sure they exist in some user folder but the key take away is that you'll connect by the connection string
(localdb)\SERVER_NAME;Integrated Security=True;Database=DATABASE_NAME
So I take it what you actually want to do is create a database called test in your LocalDB instance, but you don't have an MDF file already created for this database?
If that's the case, the code you have will fail at the connection phase since you've asked it to attach your test.mdf file.
What you would normally do in this situation is make a connection to the master database initially, and then run the create database statement which will create the test database with it's associated MDF file, maybe try changing your connection string so it looks more like this and then running again:
Integrated Security=SSPI;Data Source=(localdb)\V11.0;Initial Catalog=master
I am first time trying to use filestream to store pdf files on file system using varbinary(MAX) column type of DB.
I have followed following steps.
enabled filestream feature on SQL server 2008 R2.
Create a filegroup for BLOB storage
created table with blob column of type varbinary(max)
Now, I want to use file upload control to select file and when click on upload button it should save the pdf file. Also, how to retrieve the file?
I have tried following code
protected void btnFSupload_Click(object sender, EventArgs e)
{
SqlConnection cn = null;
SqlTransaction tx = null;
SqlCommand cmd = null;
SqlCommand cmd2 = null;
bool bCommit = false;
try
{
// read in the file to be saved as a blob in the database
FileStream input = new FileStream(#"D:\swami.pdf", FileMode.Open, FileAccess.Read);
byte[] buffer = new byte[(int)input.Length];
input.Read(buffer, 0, buffer.Length);
cn = new SqlConnection("server=at-hetal01\\sqlexpress;Initial Catalog=practice;Integrated Security=true;");
cn.Open();
tx = cn.BeginTransaction();
cmd = new SqlCommand("dbo.stp_AddBLOB", cn, tx);
cmd.CommandType = System.Data.CommandType.StoredProcedure;
SqlDataReader r = cmd.ExecuteReader(System.Data.CommandBehavior.SingleRow);
r.Read();
string id = r[0].ToString();
string path = r[1].ToString();
r.Close();
// get the transaction context
cmd2 = new SqlCommand("SELECT GET_FILESTREAM_TRANSACTION_CONTEXT()", cn, tx);
Object obj = cmd2.ExecuteScalar();
byte[] txCtx = (byte[])obj;
// open the filestream to the blob
SafeFileHandle handle = OpenSqlFilestream(path,DESIRED_ACCESS_WRITE,SQL_FILESTREAM_OPEN_NO_FLAGS,txCtx,(UInt32)txCtx.Length,0);
// open a Filestream to write the blob
FileStream output = new FileStream(handle,FileAccess.Write,buffer.Length,false);
output.Write(buffer,0,buffer.Length);
output.Close();
if (handle != null && !handle.IsClosed)
handle.Close();
bCommit = true;
}
catch (Exception ex)
{
Response.Write(ex.Message);
}
finally
{
if (cn != null)
{
switch (bCommit)
{
case true:
tx.Commit();
break;
case false:
tx.Rollback();
break;
}
cn.Close();
}
}
}
Above code shows error as below
The operating system returned the error '0xc000003a({Path Not Found} The path %hs does not exist.)' while attempting 'NtCreateFile' on 'D:\DB\FS\d11132f8-c2a8-452d-ae0c-208164a550d7\beb8e1f1-8116-440b-870b-7cef4281a15d\0000001c-000000e4-010d'. The statement has been terminated.
So, any clue on this?
If you have altered your table using SSMS table designer, the FILESTEAM column attribute will be lost producing the path not found. Make sure the FILESTREAM attribute is set for the file field by running the follwoing statement in your database:
select SERVERPROPERTY('FilestreamShareName') as ShareName,
SERVERPROPERTY('FilestreamConfiguredLevel') as ConfiguredLevel,
SERVERPROPERTY('FilestreamEffectiveLevel') as EffectiveLevel
You'll need to alter the table via a script and NOT SSMS to tie your varchar(max)/filestream field to the FileGroup you should have already created.
When I ran into this issue, I found the answer on StackOverflow, but can't seem to find it again for the reference.
I know this is old, but for future reference:
We checked the SERVERPROPERTY values that #BMP suggested. They were configured correctly, so that didn't help.
However, we went ahead and turned OFF the windows file share part of the file streaming access. Once this was done, the error went away.
In our case it was a web app running on the exact same machine as the sql server which exhibited the problem. I'm not sure if the web app's app pool user didn't have access to the file share created by windows or not.
The details were:
Windows 2003 Server (x86)
IIS 6
SQL Server 2008 R2 Express
UPDATE: Apparently this worked for a few days. It's not working any more.
