Question

i have a two table x and y. In that x table has x1 as country, x2 as country, y table has y1 as country, y2 has country. For this data, how can i get the distinct country values in this two table with this four country field?

Before that i used a single country in a single table like this,

$query="select distinct(`x1`) from x";

Now, i have the take distinct values in this two table as well as from four country values. For this union is possible. But i need any solution used in a single query without union concept.

Please provide the idea for this. Thanks in Advance…
