How to select category information from a table?

Please tell me, if there is a table where all the information is divided into, say, 2 categories, how to use $result = mysql_query(“SELECT name FROM table“) to extract only the rows of one category? The division into categories in the table takes place in a special column, where each row is assigned a category.
