c# SqlDataReader throwing syntax error, but the command runs fine in SQL Server?

Question

I'm getting a syntax error from my SQL command shown in the code below. The error is happening on the ExecuteReader line, saying

Incorrect syntax near the keyword 'JOIN'.'

I have no idea why it's throwing a syntax error, the command works perfectly fine in SQL Server. Here's the code:

private void button1_Click(object sender, EventArgs e)
{
    SqlCommand sqlcomViewSmashRoster;
    SqlDataReader dataReader;
    String strSql, strOutput ="";

    strSql = "SELECT Roster.CharacterName, Roster.TotalTournamentsParticiaped, Roster.TotalWins, Roster.TotalLosses, Roster.Championships, Roster.InjuriesCaused, Roster.Injured" +
             "FROM Roster" +
             "INNER JOIN VideoGames" +
             "ON VideoGames.VideoGame_ID = Roster.VideoGame_ID" +
             "WHERE roster.VideoGame_ID = 2";

    cnn.Open();

    sqlcomViewSmashRoster = new SqlCommand(strSql, cnn);

    dataReader = sqlcomViewSmashRoster.ExecuteReader();

    while (dataReader.Read())
    {
        strOutput = strOutput + dataReader.GetValue(0) + " - " + dataReader.GetValue(1) + "\n";
    }

    cnn.Close();

    MessageBox.Show(strOutput);
}

Thanks!

Answer 1

Whitespace. Remember that:

"abc" +
"def"

is "abcdef"

Verbatim string literals are your friend:

strSql = @"
SELECT Roster.CharacterName, Roster.TotalTournamentsParticiaped, Roster.TotalWins,
       Roster.TotalLosses, Roster.Championships, Roster.InjuriesCaused, Roster.Injured
FROM Roster
INNER JOIN VideoGames
ON VideoGames.VideoGame_ID = Roster.VideoGame_ID
WHERE roster.VideoGame_ID = 2
";

Not only is this easier to code in the first place, but you can easily copy/paste between SSMS and devenv, without having to add quotes etc.
