hi Srihari,
Thanks for replying.
But in the query that u have provided i am not getting the total count of number of rows instead getting how many times the name is there in the table.
For e.g - >
Let the table contains 5 values. like below,
sanjeet
sandeep
sam
sarmi
sapnaa
By running the querry i am getting
Sanjeet - 1
sandeep - 1
like wise.....
But i need my o/p to display all the 5 names along with count = 5
I suppose u got my question. If you need anything else please let me know. |

seems to be bit strange requirement. You can try the following query
SELECT Name, (Select count(*) from employ) as Count
from employ |

Hi,
Yah it is little bit strange only.
But this time it got corrected 50%. The o/p is coming like the following,
Code: Name count
sanjeet 5
sandeep 5
sam 5
sarmi 5
sapnaa 5
But i need the count to be displayed once only.
Means the o/p should look like the below,
Code:
Name count
sanjeet 5
sandeep
sam
sarmi
sapnaa
Thanks for all your answers.
Could you please help me regarding this issue. |

Hello Siva.
Try this
SELECT MIN(Name) AS Names, CHAR(COUNT(*)) AS Amount
FROM Employ
UNION
SELECT Name as Names, CHAR(' ') AS Amount
FROM employ
WHERE Name <> (SELECT MIN(Name) FROM Employ)
ORDER BY 1
WITH UR
But be careful. I think, the performance of this query is rather bad
Ciao, DB2Buddha |

Hello and welcome to the forums,
Did you test this query to make sure it provides the desired result?
Please do not post untested queries (regardless of your suspicion about performance). |

Hi.
I reviewed the statement. It works under the condition, that the values of the column "name" are unique. Sorry, i did not mention that. :oops:
Otherwise the statement delivers a false result. If the column "name" is not unique, even a "union all" would not deliver the desired result.

siva102,
why generate an illogical, ambigous report?
Code:
Name count
sanjeet 5
sandeep
sam
sarmi
sapnaa
why not?
Code:
Name count
sanjeet 1
sandeep 1
sam 1
sarmi 1
sapnaa 1
Total Names 5
Code:
Select name
, count(*)
from employ
group by name
Union
Select 'Total Names'
, count(*)
from employ
