Question

I am using SQl CLR for parsing some table column. I want to execute the queries also in C# user defined function. Can somebody give an example to execute select and insert queries in the function?

Thank you in advance.

 SqlConnection objSqlConn;
    string connString = string.Empty;
    connString = "Data Source=(local);Initial Catalog=DB;User ID=uname;pwd=pass;Password=pass";
    objSqlConn = new SqlConnection(connString);
    objSqlConn.Open();

    string query = "Select count(*) FROM [DB].[dbo].[TableName]";
    SqlCommand cmdTotalCount = new SqlCommand(query, objSqlConn);
    cmdTotalCount.CommandTimeout = 0;
    string TotalCountValue = cmdTotalCount.ExecuteScalar().ToString();
    return TotalCountValue;

Once you switch to C# you execute queries like you’d normally do from your application (using ADO.NET’s SqlConnection and SqlDataReader, using LINQ to SQL or using your custom build data layer).
