For example :

SQL

id   columnA

1    black
2    red
3    red
4    green
5    red
6    black
7    white

I want to count total of "black" and "red" items. Result should be "5".

This code work fine, but if I try to add "red" it's not working.

Java

long count = DatabaseUtils.longForQuery(db, "SELECT COUNT(*) FROM mytable WHERE columnA = '" + "black" + "', null);

Sorry my bad English, thanks for helping...

What I have tried:

long count = DatabaseUtils.longForQuery(db, "SELECT COUNT(*) FROM mytable WHERE columnA = ('" + "black" + "' AND '" + "red" + "'"), null);

Thanks but I didn't ask this. I want to count 2 different items in only one column.
