I'm trying to execute a stored procedure and then use an if statement to check for null values and I'm coming up short. I'm a VB guy so please bear with me if I'm making a schoolboy syntax error.
objConn = new SqlConnection(strConnection);
objConn.Open();
objCmd = new SqlCommand(strSQL, objConn);
rsData = objCmd.ExecuteReader();
rsData.Read();
if (!(rsData["usr.ursrdaystime"].Equals(System.DBNull.Value)))
{
strLevel = rsData["usr.ursrdaystime"].ToString();
}
Would this allow me to check whether the SQL connection is returning just a value and if so then populating my string?
I'm used to being able to just check the below to see if a value is being returned and not sure I'm doing it correctly with C#
If Not IsDBNull(rsData("usr.ursrdaystime"))
Any help would be appreciated!
This should work.
if (rsData["usr.ursrdaystime"] != System.DBNull.Value))
{
strLevel = rsData["usr.ursrdaystime"].ToString();
}
also need to add using statement, like bellow:
using (var objConn = new SqlConnection(strConnection))
{
objConn.Open();
using (var objCmd = new SqlCommand(strSQL, objConn))
{
using (var rsData = objCmd.ExecuteReader())
{
while (rsData.Read())
{
if (rsData["usr.ursrdaystime"] != System.DBNull.Value)
{
strLevel = rsData["usr.ursrdaystime"].ToString();
}
}
}
}
}
this'll automaticly dispose (close) resources outside of block { .. }.
