I have a function which is used as a default in a number of tables/columns.
I want to alter that function but when I do an "ALTER FUNCTION..." bit of SQL it tells me it can't be altered because it is in use - does anyone have a handy "drop all the defaults, alter function, reinstate all the defaults" type script I could cadge?

I need a count column and 2 other columns in the select query. Consider the following query:
select locid,lname,count(deviceid) AS count<br />
from failures<br />
group by locid
The above query will not work because Column 'LName' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
How can i get both the locid and lname?
Thanks

Add both columns to the GROUP BY clause.
GROUP BY locid, lname

The following sql join query is displaying "[Microsoft][ODBC SQL Server Driver]Syntax error or access violation" error
SELECT failure.locid,device.count,failure.count<br />
FROM<br />
{<br />
SELECT locality.locid,count(*) AS count<br />
FROM allotment,locality<br />
WHERE allotment.locid=locality.locid<br />
group by locality.locid<br />
} AS device<br />
FULL OUTER JOIN<br />
{<br />
SELECT locid,count(deviceid) AS count<br />
FROM failures<br />
group by locid<br />
} AS failure ON device.locid = failure.locid
device is used to find number of device in a particular locality
failure is to find the number of failures in the particular location
Both device and failure queries are working fine separately.
All localities are stored in locality table. the alloted devices are in allotment table, failures are in failures table
Please correct the error in the query. Thanks.

Where do you think?
I highlighted the fact you were using braces {} and that it was wrong. Replace the {} with ()

Hi,
why the select query is not returning the decimal value?
consider the following query:
select 1/2
it is returning 0
it must return 0.5 Please help.
Thanks
|
|
|
|
|
Because it is doing an integer division and truncating everything past the decimal point.
use SELECT 1.0/2.0

I need to use the colname. for eg: select colname1/colname2 from table
the colname1 has the value 1 & colname2 has the value 2
thanks

Then cast the column values to floats
SELECT CAST(colname1 AS FLOAT) / CAST(colname2 AS FLOAT) FROM MyTable

What is the structure of your table? (i.e. field names and data types)

Sorry, I don't understand what you want.
To update a row in a table you can use
UPDATE MyTable SET Qty = 70 WHERE saleno = 5

Hi Balu,
Here's your reply.
If you have a proper sequence with no missing links use the following:
Select a.saleno,b.saleno, coalesce(a.qty,0)+coalesce(b.qty,0) as Qty
from tbl_Sale a left join tbl_sale b
ON a.saleno=b.saleno+1
Else use the following:-
Select a.saleno,coalesce(a.qty,0)+COALESCE((Select b.Qty from tbl_Sale b where b.saleno=
(Select max(c.saleno) from tbl_sale c where c.saleno

Oh! I see what he was getting at now. I really do wish people would say what they want rather than have everyone guess what they want through some cryptic IQ test what-is-the-next-number-in-the-sequence style question.
