internal class PagingHelper
{
    public static String ParseQueryForPagingAndSorting(String strSQL, string SortExpression, int StartIndex, int EndIndex)
    {
        if (String.IsNullOrEmpty(SortExpression))
            SortExpression = " (select 0)";
        StringBuilder sb = new StringBuilder();
        sb.Append("select * from (");
        sb.Append(" select ROW_NUMBER() OVER (ORDER BY " + SortExpression + ") AS row_num,");
        int index = strSQL.ToLower().IndexOf('t', 0);
        sb.Append(strSQL.Substring(index + 2));
        sb.Append(")");
        sb.Append(" AS TempTable");
        sb.Append(" where row_num>=" + StartIndex.ToString() + " AND row_num<=" + EndIndex.ToString());
        return sb.ToString();
    }
    public static String ParseQueryForCount(String strSQL)
    {
        StringBuilder sb = new StringBuilder();
        sb.Append("select count(*) from");
        sb.Append("(");
        sb.Append(strSQL);
        sb.Append(")");
        sb.Append(" AS TempTable");
        return sb.ToString();
    }
}
