I am trying to connect to Sql Azure use the ADO.net connection still provided by the portal. It is of the format
var connectionstring =
"Server=tcp:abcdefghij.database.windows.net,1433;Database=[myDatabase];User ID=[myName]#abcdefghij;Password=[]myPassWord;Trusted_Connection=False;Encrypt=True;Connection Timeout=30;"
When I pass this connection string to the DbContext constructor it falls over. The error message is
"The type initializer for 'System.Data.Entity.ModelConfiguration.Utilities.TypeExtensions' threw an exception."
Any ideas what the problem can be?
Thanks

Did anyone was able to connect to database using Spring boot, R2DBC and encrypted connection
I have a connection string:
jdbc:sqlserver://XXX.XX.XXXX:1433;encrypt=true;trustServerCertificate=true;databaseName=ABC
I am using connection factory builder class and parsed arguments as shown below:
public ConnectionFactory connectionFactory() {
final ConnectionFactoryOptions options = builder()
.option(DRIVER, "sqlserver")
.option(HOST, applicationDatabaseProperties.getHost())
.option(PORT, applicationDatabaseProperties.getPort())
.option(USER, applicationDatabaseProperties.getUsername())
.option(PASSWORD, applicationDatabaseProperties.getPassword())
.option(DATABASE, applicationDatabaseProperties.getDatabase())
.option(SSL, true)
.build()
return ConnectionFactories.get(options);
}
It gives me a runtime SSL error when I am trying to connect
I tried to add an option as shown below - I saw it in the documentation:
.option(Option.valueOf("[trustServerCertificate]","[true]"))
but compiler gives the error(using it from Kotlin code), I decompiled original class io.r2dbc.spi.ConnectionFactoryOptions
and trustServerCertificate is not listed as a constant
Any help would be greatly appreciated
Thanks, Sam
Tried adding the option .option(Option.valueOf("[trustServerCertificate]","[true]")) to the builder,
compiler returns the error
I need connect my Firebird data base (.IDB) in KNIME. I used Database Connector node, but I have this notice:
ERROR Database Connector 0:1 Execute failed: Could not create
connection to database: Invalid connection string
C:\Users\miPC\Desktop\DataBase1.IDB, reason: null or empty database
name in connection string
The error suggest that you have used the following connection string:
jdbc:firebirdsql://C:\Users\miPC\Desktop\DataBase1.IDB
That is incorrect as it is missing the host name. The correct URL would be:
jdbc:firebirdsql://localhost/C:\Users\miPC\Desktop\DataBase1.IDB
Please consult the Jaybird FAQ for valid URL formats.
I'm using SQLProvider to connect to my (local) PostgreSQL database in F#.
I've started with this code from fsprojects:
open FSharp.Data.Sql
open Npgsql
let [<Literal>] ResolutionPath =
__SOURCE_DIRECTORY__ + #"/../../packages/Npgsql/lib/net451/"
[<Literal>]
let connectionString = "Host=localhost;Port=5432;User ID=test;Password=test;Database=testdb;"
type PostgreSQL =
SqlDataProvider<
Common.DatabaseProviderTypes.POSTGRESQL,
ConnectionString = connectionString,
ResolutionPath = ResolutionPath,
IndividualsAmount = 1000,
UseOptionTypes = true>
When I'm trying to compile it I get this error message:
(path)/Database.fs(60,9): error FS3033: The type provider 'FSharp.Data.Sql.SqlTypeProvider' reported an error: Could not create the connection, most likely this means that the connectionString is wrong. See error from Npgsql to troubleshoot: The type initializer for 'Npgsql.Counters' threw an exception.

See error from Npgsql to troubleshoot: The type initializer for 'Npgsql.Counters' threw an exception.
I've checked that user id and password and everything in connection string is correct.
I actually don't have any idea how to debug this issue.
Do you know what could be wrong?
Does it work for you without any issues?
I'm using macOS 10.12.
And lastly, in case I won't be able to fix this, are there any other methods that you would recommend for connecting to postgreSQL (with type providers)?
The error message clearly says that an exception was thrown from the type initializer for Npgsql.Counters - this is Npgsql 3.2's new support for Windows performance counters.
Unfortunately it seems that there are several issues with performance counters in various scenario (see #1447 and #1435). Because of this, version 3.2.2 (to be released this week) won't make use of them by default.
Can you please confirm that you're using 3.2.1 (and not 3.2.0), because a partial fix was introduced? If you're using 3.2.1 and getting this exception, you'll have to wait a few days for 3.2.0, and can use 3.1.10 in the meantime where the exception won't be thrown.
I tried this tutorial
http://www.asp.net/mvc/tutorials/getting-started-with-ef-using-mvc/creating-an-entity-framework-data-model-for-an-asp-net-mvc-application
And when I tried following step
enable-migrations -contexttypename SchoolContext
It results as follows
"An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct"
Any help would be greatly appreciated.
I am using SQL Server 2005 Express with SQL Servre authentication and remote connections enabled although I am working locally.
My web.config connection string part:
<add name="HelpDesk2connect" connectionString="metadata=res://*/Models.Model1.csdl|res://*/Models.Model1.ssdl|res://*/Models.Model1.msl;provider=System.Data.SqlClient;provider connection string='Data Source=SATURN;Initial Catalog=HelpDesk2;Integrated Security=False;user id=sa;password=*******;multipleactiveresultsets=true'" providerName="System.Data.EntityClient" />
I am logging in as sa
In the controller I get these errors (in this statement: `return View(db.Tickets.ToList());)
An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct.
The provider did not return a ProviderManifestToken string.
In the page I get this error:
[SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 52 - Unable to locate a LocalDB installation. Verify that SQL Server Express is properly installed and that the LocalDB feature is enabled.)]
Can you help me spot what am I doing wrong?
Thanx in advance
