title: Selecting Multiple Cells (SQL, WinForms)
body: <p>Good afternoon! I have a problem:</p>
  <p>I need to select a pair of cells from one database table (which I know how to do), and after that I need to put all the cells from another database that satisfy the condition in the same row.</p>
  <p>For example, I need columns &quot;1&quot;, &quot;2&quot; and &quot;3&quot; from table &quot;A&quot;, and all cells of column &quot;3&quot; from table &quot;B&quot;, where [B].[2] == [A].[1] in one row.</p>
  <p>But alas, it only turns out that I have a huge number of rows, where there is only one cell from column [B].[3]. I couldn't find anything on the forums / documentation, alas..</p>
