Getting published articles from mysql

[etrader]

I capture a list of my articles from mysql by this command

mysql_query("SELECT * FROM Text WHERE Key='$key'") 

Now I added a column for published and draft to be identified by 1 and 0, respectively. What is the best way to show only published articles? Adding a WHERE condition? What is the most common method in major CMSes?

 

Thanks

mysql_query("SELECT * FROM Text WHERE Key='$key' && status = 1");
