Hi
How can I merge the result of few quries that had been unioned ?
example:
SELECT item1,item2,item3 FROM table111 WHERE item2='something' GROUP BY item1
UNION
SELECT item1,item2,item3 FROM table222 WHERE item2='something' GROUP BY item1
UNION
SELECT item1,item2,item3 FROM table333 WHERE item2='something' GROUP BY item1
NOTE:
table111, table222, and table333 has the same structure
always i'm asking for same items to be selected here and for same group by and where statment
the difference is with the table names
each table has different records than the other table
Is there any available code to do this ! any solution !
do you any idea of how doing this, do you have any simple example ?

Create a view for the query and then use group by!

I've got one solution but still have one more problem
I'm getting the most biggest count from multible tables this is what i'm using: PHP Code:
status1 = 40 items status2 = 60 items and if my second table gives: status1 = 250 status2 = 20 the result from the above code is: status1 = 250 status2 = 60 which is not what i'm looking for (it's just outputing the biggest numbers) i want is this answer: status1 = 290 status2 = 80 what do you think ? : ( |

don't worry
I've figured out the solution I just needed to used UNION ALL instead of UNION Thanks
