Connection string - Keyword not supported: 'initial catalog' - asp.net

Question

I am using Webmatrix.data's Database entity to create a database connection, however it doesnt like my connection string. I am running it from MVC ASP.net.
Ive tried changing it to server / database, but still errors the same. Where am I going wrong?
using (var db = Database.OpenConnectionString(#"Data Source=MY-HP\Serv;Initial Catalog=MyDBSQL;User ID=sa;Password=password"))
{
var items = db.Query("SELECT * FROM TaskPriority");
}
Exception Details: System.ArgumentException: Keyword not supported: 'initial catalog'.

Answer 1

check here: Database.OpenConnectionString Method (String, String)
try to specify the provider name as second parameter, from the MSDN example:
var connectionString = "Data Source=.\\SQLExpress;Initial Catalog=SmallBakery;Integrated Security=True";
var providerName = "System.Data.SqlClient";
var db = Database.OpenConnectionString(connectionString, providerName);

ARRRRHHHHHH!!!!!
This is the second time I've run into this, grrrh - wasted hours on it.
Error:
The server encountered an error processing the request. The exception message is 'Keyword not supported: 'initial catalog;MyDatabase;data source'.'. See server logs for more details. The exception stack trace is:

This was my faulty connection string:
<add name="Production" connectionString="Password=Secret;Persist Security Info=True;User ID=MyUserID;Initial Catalog;MyDatabase;Data Source=aquickborwnfoxjumpedover.us-west-2.rds.amazonaws.com,1433" providerName="System.Data.SqlClient" />
Looks good right? WRONG
Eventually I spotted the semi-colon here:
Initial Catalog;MyDatabase
To correct it, I used an equal sign:
Initial Catalog=MyDatabase
The correct connection string:
<add name="ConnString" connectionString="Password=Secret;Persist Security Info=True;User ID=MyUserID;Initial Catalog=MyDatabase;Data Source=aquickborwnfoxjumpedover.us-west-2.rds.amazonaws.com,1433" providerName="System.Data.SqlClient" />

Answer 3

You can use the below code
Config file :
<connectionStrings>
<add name="con" connectionString="Data Source=ServerName;Initial Catalog=master;Integrated Security=SSPI;" providerName="System.Data.SqlClient"></add>
</connectionStrings>
cshtmlfile :
var db = Database.Open("con");
var selecteddata = db.Query("select * from movie");

Answer 4

I ran into the error in one of the IdentityServer quickstarts.
Had to replace
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlite(Configuration.GetConnectionString("DefaultConnection")));
With
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
Using
Microsoft.EntityFrameworkCore.SqlServer
Because obviously my DB was a Microsoft SQL Server and not SQLite.

Answer 5

For me I was getting this error because I was using a templated solution. Unbeknownst to me the template only installed support for sqlite. I had to install Microsoft.EntityFrameworkCore.SqlServer and change the calls in my code from UseSqlite to UseSqlServer.

Answer 6

You need to check your connection string.
I received the error because I had db(instead of 'Database') in my connection string.
"DevConnection": "server=DEL1-XX-XXXX;db=DonationDb;user=sa;password=XXXX"
Updating the above connection string(db to Database) should solve the problem. Below is the working connection string.
"DevConnection":"server=DEL1-XX-XXXX;Database=DonationDb;user=sa;password=QwerXXXX"

Answer 7

I suggest:
You can check your connection string format clearly especialy " and ". In my case this is:
You may try generate db by EF again.
