Solution 1

I strongly recommend to read this:
SELECT Examples (Transact-SQL)[^]
Visual Representation of SQL Joins[^]

SQL

SELECT t1.*, t2.*
FROM Table1 AS t1 INNER JOIN Table2 AS t2 ON t1.Key = t2.ForeignKey

[EDIT]
Use DataAdapter[^] or DataSet[^]. To bound data, try:

VB

DataGridView1.DataSource = DataSet.Tables(0)
DataGridView2.DataSource = DataSet.Tables(1)

there exist two different 'select' in your query string. divide them into two different SqlCommand (at least, different times with a single SqlCommand) like:

C#

using(cmd = new SqlCommand("query1")) {
 SqlDataReader reader = cmd.ExecuteReader();
 // do someting

 cmd.CommandText = "query2";
 reader = cmd.ExecuteReader();
 // do some other thing.
}

see here: SqlCommand[^]
and here: SqlDataReader[^]
