I'm trying to implement a Common Language Runtime (CLR) assembly to use with SQL Server. For creating dll I'm using Visual Studio 2019.
I have the following code from an example tutorial:
using System;
using System.Collections;
using System.Text;
using System.Data;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
namespace Split
{
public class Class1
{
[SqlFunction(
DataAccess = DataAccessKind.None,
FillRowMethodName = "MyFillRowMethod"
, IsDeterministic = true)
]
public static IEnumerable Split(string stringToSplit, string delimiters)
{
string[] elements = stringToSplit.Split(delimiters.ToCharArray());
return elements;
}
public static void MyFillRowMethod(Object theItem, out SqlChars results)
{
results = new SqlChars(theItem.ToString());
}
}
}
But I encounter this error:
Error CS0234 The type or namespace name 'SqlServer' does not exist in the namespace 'Microsoft' (are you missing an assembly reference?)
Can anybody show me the way of fixing my problem?
SqlServer. Server namespace, you can create stored procedures, triggers, user-defined types, user-defined functions (both scalar and table-valued), and user-defined aggregate functions in any supported . NET Framework language. You can also register them in SQL Server.
Data. SqlClient. This assembly (namespace) of . NET Framework contains all of the classes required to connect to a SQL Server database and read, write, and update.
SqlLocalDb.Dac. A library that makes it easy to do integration testing with SQL Server using a local DB. 13.0K. DbTestMonkey.Providers.SqlServer. SqlServer specific provider for DbTestMonkey.
Microsoft SQL Server 2019 Express is a free, feature-rich editions of SQL Server that is ideal for learning, developing, powering desktop, web & small server applications, and for redistribution by ISVs.
As the error message hinted at:
You're probably missing the reference to System.Data.SqlClient
, which contains the SqlFunctionAttribute
in the Microsoft.SqlServer.Server
namespace.
Right click on your project and click on Manage NuGet Packages...
Search for System.Data.SqlClient
Install
That should resolve your issue.
