UDF In Where Clause
Sep 1, 2003
we trying to use a UDF in Where Clause. This is taking too much of time. when we replaced the UDF with a subquery the query is fast.
Eg:
select Name, Designation, Address From Employee Where dbo.GetAge(EmpId) > 25
This is taking very long to fetch 12 records from 22,00,000 records.
When the same query has been converted to
select E.Name, E.Designation, E.Address From Employee E Where (select datediff("YY", EP.DOB, GETDATE()) from EmpPersonaldetail EP where EP.Empid= E.EmpId)
this gets executed very fast.
What could be the reason?
Pls help.

I have a quite big SQL query which would be nice to be used using UNION betweern two Select and Where clauses. I noticed that if both Select clauses have Where part between UNION other is ignored. How can I prevent this?
I found a article in StackOverflow saying that if UNION has e.g. two Selects with Where conditions other one will not work. [URL] ....
I have installed SQL Server 2014 and I tried to use tricks mentioned in StackOverflow's article but couldn't succeeded.
Any example how to write two Selects with own Where clauses and those Selects are joined with UNION?

I am working with a vendor on upgrading their application from SQL2K to SQL2K5 and am running into the following.
When on SQL Server 2000 the following statement ran without issue:
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
WHERE Processed = 0 AND LegNum = 1
AND TrackID IN
(
SELECT TrackID
FROM dbo.Track_ID
GROUP BY TrackID
HAVING MAX(LegNum) = 1 AND
TrackID + 'x1' IN
(
SELECT
dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID))
FROM dbo.Track_ID INNER JOIN dbo.transactions
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
)
Once moved to SQL Server 2005 the statement would not return and showed SOS_SCHEDULER_YIELD to be the waittype when executed. This machine is SP1 and needs to be upgraded to SP2, something that is not going to happen near time.
I changed the SQL to the following, SQL Server now runs it in under a second, but now the app is not functioning correctly. Are the above and the following semantically the same?
UPDATE dbo.Track_ID
SET dbo.Track_ID.Processed = 4 --Regular 1 leg call thats been completed
WHERE Processed = 0 AND LegNum = 1
AND TrackID IN
(
SELECT TrackID
FROM dbo.Track_ID
WHERE TrackID + 'x1' IN
(
SELECT dbo.Track_ID.TrackID + 'x' + CONVERT(NVARCHAR(2), COUNT(dbo.Track_ID.TrackID))
FROM dbo.Track_ID INNER JOIN dbo.transactions
ON dbo.Track_ID.SM_ID = dbo.transactions.sm_session_id
GROUP BY dbo.Track_ID.TrackID
)
GROUP BY TrackID
HAVING MAX(LegNum) = 1
)

2 examples:
1) Rows ordered using textual id rather than numeric id
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
order by
v.id
Result set is ordered as: 1, 11, 2
I expect: 1,2,11
if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
2) SQL server reject query below with next message
Server: Msg 169, Level 15, State 3, Line 16
A column has been specified more than once in the order by list. Columns in the order by list must be unique.
Code Snippet
select
cast(v.id as nvarchar(2)) id
from
(
select 1 id
union select 2 id
union select 11 id
) v
cross join (
select 1 id
union select 2 id
union select 11 id
) u
order by
v.id
,u.id
Again, if renamed or removed alias for "cast(v.id as nvarchar(2))" expression then all works fine.
It reproducible on
Microsoft SQL Server 2000 - 8.00.2039 (Intel X86) May 3 2005 23:18:38 Copyright (c) 1988-2003 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
and
Microsoft SQL Server 2005 - 9.00.3042.00 (Intel X86) Feb 9 2007 22:47:07 Copyright (c) 1988-2005 Microsoft Corporation Developer Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
In both cases database collation is SQL_Latin1_General_CP1251_CS_AS
If I check quieries above on database with SQL_Latin1_General_CP1_CI_AS collation then it works fine again.
Could someone clarify - is it bug or expected behaviour?

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.

hi..
i have basic question like
what is differance between conditions put in ON clause and in WHERE clause in JOINS????
see conditions that shown in brown color
select d1.SourceID, d1.PID, d1.SummaryID, d1.EffectiveDate,
d1.Audit, d1.ExpirationDate, d1.Indicator
from[DB1].[dbo].[Implicit] d1 inner join [DB2].[dbo].[Implicit] d2
on d1.SummaryID=d2.SummaryID
AND d1.ListType = d2.ListType
AND (d1.EffectiveDate <= d2.ExpirationDate or d2.ExpirationDate is null)
AND (d1.ExpirationDate >= d2.EffectiveDate or d1.ExpirationDate is null)
whered1.ImplicitID >= d2.ImplicitID AND
(d1.SourceID<>d2.SourceID
OR (d1.SourceID IS NULL AND d2.SourceID IS NOT NULL)
OR (d1.SourceID IS NOT NULL AND d2.SourceID IS NULL)
)
select d1.SourceID, d1.PID, d1.SummaryID, d1.EffectiveDate,
d1.Audit, d1.ExpirationDate, d1.Indicator
from[DB1].[dbo].[Implicit] d1 inner join [DB2].[dbo].[Implicit] d2
on d1.SummaryID=d2.SummaryID
AND d1.ImplicitID = d1.ImplicitIDAND d1.ListType = d2.ListType
AND (d1.EffectiveDate <= d2.ExpirationDate or d2.ExpirationDate is null)
AND (d1.ExpirationDate >= d2.EffectiveDate or d1.ExpirationDate is null)
whered1.ImplicitID >= d2.ImplicitID AND
(d1.SourceID<>d2.SourceID
OR (d1.SourceID IS NULL AND d2.SourceID IS NOT NULL)
OR (d1.SourceID IS NOT NULL AND d2.SourceID IS NULL)
)
another thing...
if we put AND d1.ImplicitID = d1.ImplicitID condition in second query then shall we remove
d1.ImplicitID >= d2.ImplicitID from WHERE clause????

Example, suppose you have these 2 tables(NOTE: My example is totally different, but I'm simply trying to setupthe a simpler version, so excuse the bad design; not the point here)CarsSold {CarsSoldID int (primary key)MonthID intDealershipID intNumberCarsSold int}Dealership {DealershipID int, (primary key)SalesTax decimal}so you may have many delearships selling cars the same month, and youwanted a report to sum up totals of all dealerships per month.select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',sum(cs.NumberCarsSold) * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDMy question is, is there a way to achieve something like this:select cs.MonthID,sum(cs.NumberCarsSold) as 'TotalCarsSoldInMonth',TotalCarsSoldInMonth * d.SalesTax as 'TotalRevenue'from CarsSold csjoin Dealership d on d.DealershipID = cs.DealershipIDgroup by cs.MonthIDNotice the only difference is the 3rd column in the select. Myparticular query is performing some crazy math and the only way I knowof how to get it to work is to copy and past the logic which isgetting out way out of hand...Thanks,Dave

Hey guys, I'm a bit weak when it comes to doing ands and or's. I know what i want, but when I put it into statement, i dont get the results that i want.
I have 3 fields in my where clause. ID, LW, and LWU. The code is as follows:WHERE (LASTVISIT BETWEEN '1 / 1 / 95 12 : 00 : 00 AM' AND '1 / 1 / 06 12 : 00 : 00 AM') AND (ID NOT LIKE '%6%') AND (ID NOT LIKE '%7%') AND (ID NOT LIKE '%8%') AND (LW <> 1) AND (LWU <> 'test') OR (LASTVISIT BETWEEN '1 / 1 / 95 12 : 00 : 00 AM' AND '1 / 1 / 06 12 : 00 : 00 AM') AND (ID IS NULL) AND (LW <> 1) AND (LWU <> 'test')
I have a range of dates that I want to grab, in there I do not want any records where ID has 6,7,8 and I only want records where LW does not equal 1. UP to this point, it works fine. I get all the records that only return these values. However, the moment I add where LWU does not equal 'test'. it does not return the values I want. Furthermore, why can I not put this whole string into one and clause? I never understood why I had to create a second line following OR. the longer this query gets the more I get confused. Any help?

I'm having a heck of time with this where clause. I have a table that contains client addresses, a client can have more than one address. So some of the addresses may be seasonal. I need to return only the current address based on a flag MailTo (bit) and a date range, just the month and day, the start and end are datetime datatypes.
Here is what i have tried:
I would really would like it to work on a range of month and day based on the startdate and enddate fields and the MailTo flag.
The table looks like this;
tblClientAddresses:
Address_ID,Client_ID,Address,Address2,City,State,Zip,Country,AddressType,StartDate,
EndDate,MailTo
WHERE (A.MailTo=1) AND (A.EndDate Is Null OR DatePart(mm,A.Enddate) >= DatePart(mm,GETDATE()) AND DatePart(dd,A.Enddate) >= DatePart(dd,GETDATE()))
Thank you for any help!

Hi,
I am working on a project involving text searching. I created a fulltext catalog on the database and scheduled it for every one minute. I created a fulltext index on a table and added some columns. I scheduled it as the database catalog. I ran a simple query like this in the query analyzer but got an error message that the catalog does not exist!
SELECT * FROM tbl_extra_skills WHERE CONTAINS(ITSkills, 'Word')
What am I doing wrongly?

Hello,
I would like to create a "where in" clause on the fly. For example, if a user types into a text box three email address separated by a comma, I can not do a select on them because they are not strings - (adam@homebusiness.to, wanshark1@yahoo.com, test@test.com) <--- They should be ('adam@homebusiness.to', 'wanshark1@yahoo.com', 'test@test.com') Is there a sql function that tells the server that the stuff in parenthesis is a string? Thanks

Hi,
I'm desperatly trying to make a query (inside a stored procedure which handles diferent tables and columns for each time) on which I have a variable as the table name. The problem is that I cant make it with the variable. What I need to do is something like this:
select @max_value=MAX(COL_NAME(@tableID,@columnID))
from (and here is my problem) @table(or @tableId or something :confused: )
I already tried with OBJECT_NAME but i can't do it, and there's no way i can know the table's name 'cause the idea is to perform the procedure to several tables.
Thanks in advance,

I am trying to select the rows where the sum of their quantity(qty) + 1 = 4.
This is the syntax I am trying to use (which does not return any rows)
select serial
from cases
group by serial
having ((sum(qty) + 1) = 4)
Desired results:
serial
53565
53566
I'm probably doing something real stupid up there...so any I'd appreciate any help :)

From a web page (UD4), I am trying to run a SP. I want to pass 3 variable to the SP. A beginning date, ending date and string to be used in an IN() statement. I can hard code the SP as below and it returns a value. But When I declare @DeptHdr and change the code to Dept IN (@DeptVar) and then try to pass the string 42500, 43500, it does not return any values.
Is it possible to pass a variable this way into an IN statement?

hi all...!
i wonder how to ignore the where clause(i mean partially) when the parameter is null? i mean :-
if parameter @tempudf1 is set to null, then i need to search any values (including null) from the recvudf1 column.. but if @tempudf1='something', i need to search only values that contains 'something' from column recvudf1..
if i do like this :-
where d.recvudf1 like isnull(@tempudf1,'%') it will exclude the <NULL> values in the column recvudf1 whereas i need to search all no matter it null or not... thanks..
note : i could have 1-10 recvudf so the where clause will look something like this :-
where d.recvudf1 like isnull(@tempudf1,'%') AND
d.recvudf2 like isnull(@tempudf2,'%') AND
d.recvudf3 like isnull(@tempudf3,'%') --> to recvudf10
~~~Focus on problem, not solution~~~
