    <p>Here is my try inspired from the comments on my question, and many thanks to everybody:</p> <pre><code>class Program { static void Main(string[] args) { using (SqlConnection con = new SqlConnection("server=myserver;database=mydb;user id=sa;password=mypassword;")) { Console.WriteLine(GetCreateTableFromSqlCode(@" SELECT ID,Eid,Keyword AS Keywords,KeywordType AS Sources,Year FROM Eid_Keywords WHERE Eid IN(SELECT Eid FROM ReviewersPublications)","Keywords",con)); } } public static string GetCreateTableFromSqlCode(string sqlSelect,string tableName, SqlConnection con) { SqlCommand cmd = new SqlCommand(string.Format("SET FMTONLY ON;\r\n{0}\r\nSET FMTONLY OFF;",sqlSelect), con); try { con.Open(); SqlDataReader reader = cmd.ExecuteReader(); DataTable dt = reader.GetSchemaTable(); reader.Close(); return GetCreateTableScript(dt, tableName); } finally { if (con.State == ConnectionState.Open) con.Close(); } } private static string GetCreateTableScript(DataTable dt,string tableName) { string snip = string.Empty; StringBuilder sql = new StringBuilder(); sql.AppendFormat("CREATE TABLE {0}\r\n(\r\n",tableName); for (int i = 0; i &lt; dt.Rows.Count;i++) { DataRow dr = dt.Rows[i]; snip = GetColumnSql(dr); sql.AppendFormat((i &lt; dt.Rows.Count - 1) ? snip : snip.TrimEnd(',','\r','\n')); } sql.AppendFormat("\r\n)"); return sql.ToString(); } private static string GetColumnSql(DataRow dr) { StringBuilder sql = new StringBuilder(); sql.AppendFormat("\t[{0}] {1}{2} {3} {4},\r\n", dr["ColumnName"].ToString(), dr["DataTypeName"].ToString(), (HasSize(dr["DataTypeName"].ToString())) ?

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
