SQL Server Data Rows exception incorrect syntax

I am working on a function and getting an error that keeps pointing in the area where the DataTable object is getting declared but it is only giving the following error (see below). Can someone tell me what I am missing?

Code:

SqlConnection myConnection = ConfigManager.SqlConnection;

/// <summary>
/// Load Data Rows for Section Type ID
/// </summary>
public void LoadSectionTypeIDList()
{
     String sql = "SELECT DISTINCT section_type_id"
                + "FROM [claims_module].[dbo].[template_clob_gl]"
                + "ORDER BY section_type_id";

     SqlDataAdapter myAdapter = new SqlDataAdapter(sql, myConnection);
     DataSet ds = new DataSet();
     myAdapter.Fill(ds, "claims_module");

     DataTable dt = ds.Tables["claims_module"];
     SectionDropDownList.Items.Add("Select");

     foreach (DataRow r in dt.Rows)
     {
         SectionDropDownList.Items.Add(r["section_type_id"].ToString());
     }
}

Error:

System.Data.SqlClient.SqlException (0x80131904): Incorrect syntax near '.'.

I noticed that it was a syntax error from missing spaces between the sql statement. Once I fixed it, the statement ran and the list appeared.
