I have a table

________________________________________________________________________________
|                         Message                                               |
|_______________________________________________________________________________|
| ID(INT) |  Text(TEXT) |read(TINYINT(0/1)) |deleted(TINYINT(0/1))|  User_id    |
| 1       | How Are You?|      0            |        0            |    6        |
| 2       | Fine        |      0            |        1            |    4        |
| 3       | Message 3   |      1            |        0            |    6        |
| 4       | Message 4   |      0            |        1            |    6        |
| 5       | Message 5   |      1            |        0            |    5        |

Now I want to select the message where user_id=6 and also select the column count for read=0 and read=1 seperately.I know this can be done by group by command and iam currently doing it with two sql queries .May somebody join them in one

select message,count(*) from message where User_id=6 and read=0 group by id;//for unread message
select message,count(*) from message where User_id=6 and read=1 group by id;//for read message

Answer 1

Why don’t you

select
  message,
  sum(read) as num_read,
  sum(case read when 0 then 1 else 0 end) as num_unread
from message
where user_id = 6
group by user_id

? You can drop either the where or the group by line, depending on your real need and SQL implementation.
