Having clause without GROUP BY clause?

Hi,

What is HAVING clause equivalent in the following oracle query, without the combination of "GROUP BY" clause ?

eg :

SELECT SUM(col1) from test HAVING col2 < 5

SELECT SUM(col1) from test WHERE x=y AND HAVING col2 < 5

I want the equivalent query in MSSQLServer for the above Oracle query.

Also, does the aggregate function in Select column(here the SUM(col1)) affect in anyway the presence of HAVING clause?.

Thanks,
Gopi.those queries actually run in oracle? i rather doubt it

without a GROUP BY, the entire table is considered a single group

the individual col2 values would not necessarily all be the same, therefore the HAVING condition in the first query would not necessarily give you the results you want, assuming it even runs, which i doubt

in the second query you will surely get a syntax error even in oracle

perhaps what you want for the two queries is:

SELECT SUM(col1) from test where col2 < 5

SELECT SUM(col1) from test WHERE x=y AND col2 < 5|||Sorry for the typos. Actually the queries are as follows.

SELECT SUM(col1) from test HAVING SUM(col2) < 5

SELECT SUM(col1) from test WHERE x=y HAVING SUM(col2) < 5

Thanks,
Gopi.|||do you have sql server? if so, why don't you test those queries and see what you get

Have Insert statement, need equivalent Update.

Using ms sql 2000
I have 2 tables.
I have a table which has information regarding a computer scan. Each
record in this table has a column called MAC which is the unique ID for
each Scan. The table in question holds the various scan results of
every scan from different computers. I have an insert statement that
works however I am having troulbe getting and update statement out of
it, not sure if I'm using the correct method to insert and thats why or
if I'm just missing something. Anyway the scan results is stored as an
XML document(@.iTree) so I have a temp table that holds the relevent
info from that. Here is my Insert statement for the temporary table.
INSERT INTO #temp
SELECT * FROM openxml(@.iTree,
'ComputerScan/scans/scan/scanattributes/scanattribute', 1)
WITH(
ID nvarchar(50) './@.ID',
ParentID nvarchar(50) './@.ParentID',
Name nvarchar(50) './@.Name',
scanattribute nvarchar(50) '.'
)
Now here is the insert statement for the table I am having trouble
with.
INSERT INTO tblScanDetail (MAC, GUIID, GUIParentID, ScanAttributeID,
ScanID, AttributeValue, DateCreated, LastModified)
SELECT @.MAC, #temp.ID, #temp.ParentID,
tblScanAttribute.ScanAttributeID, tblScan.ScanID,
#temp.scanattribute, DateCreated = getdate(), LastModified =
getdate()
FROM tblScan, tblScanAttribute JOIN #temp ON tblScanAttribute.Name =
#temp.Name
If there is a way to do this without the temporary table that would be
great, but I haven't figured a way around it yet, if anyone has any
ideas that would be great, thanks.Because your procedure don't use sp_executeSql you can use a table variable,
not a temp table.
Declare @.Tab table
(
Field1 nvarchar(10),
Field2 int,
...(exactly the fields in the xml file)
)
INSERT INTO tblScanDetail (MAC, GUIID, GUIParentID, ScanAttributeID,
ScanID, AttributeValue, DateCreated, LastModified)
SELECT @.MAC, @.Tab.ID, @.TabParentID,
tblScanAttribute.ScanAttributeID, tblScan.ScanID,
@.Tab.scanattribute, getdate(), getdate()
FROM tblScan
INNER JOIN tblScanAttribute
JOIN@.Tab ON tblScanAttribute.Name =
@.Tab.Name
Of course fields must match...
Hope it helps

that will do what my insert does accept I need it to be an update

once for each client.

INSERT INTO #temp
SELECT * FROM openxml(@.iTree,
'ComputerScan/scans/scan/scanattributes/scanattribute', 1)
WITH(
ID nvarchar(50) './@.ID',
ParentID nvarchar(50) './@.ParentID',
Name nvarchar(50) './@.Name',
scanattribute nvarchar(50) '.'
)

Now here is the insert statement for the table I am having trouble
with.

INSERT INTO tblScanDetail (MAC, GUIID, GUIParentID, ScanAttributeID,
ScanID, AttributeValue, DateCreated, LastModified)
SELECT @.MAC, #temp.ID, #temp.ParentID,
tblScanAttribute.ScanAttributeID, tblScan.ScanID,
#temp.scanattribute, DateCreated = getdate(),
LastModified =
getdate()
FROM tblScan, tblScanAttribute JOIN #temp ON
tblScanAttribute.Name =
#temp.Name

If there is a way to do this without the temporary table that would be
great, but I haven't figured a way around it yet, if anyone has any
ideas that would be great, thanks.rhaazy (rhaazy@.gmail.com) writes:

I have some difficulties to understand what your problem is. If all
you want to do is to insert from the XML document, then you don't
need the temp table, but you could use OPENXML directly in the
query.

But then you talk about an UPDATE as well, and if your aim is to insert
new rows, and update existing, it's probably better to use a temp
table (or a table variable), so that you don't have to run OPENXML twice.
Some DB engines support a MERGE command which performs the task of
UPDATE and INSERT in one statement, but this is not available in
SQL Server, not even in SQL 2005.

If this did not answer your question, could you please clarify?

Books Online for SQL Server 2000 at
http://www.microsoft.com/sql/prodin...ions/books.mspx|||My app runs on all my companies PCs every month a scan is performed and
the resulst are stored in a database. So the first time a scan is
performed for any PC it will be an insert, but after that it will
always be an update. I tried using openxml in my insert statement but
kept getting an error stating my sub query is returning more than one
result... So since I couldn't do it that way I'm trying this method.
All the relevent openxml is there I just couldn't figure out how to
insert each column using it. If you have any suggestions I'm open to
give it a try.
