Intensively Used Function In View Needs A Minimum And Maximum From A Table PartII
Jul 23, 2005
Because of an error in google or underlying site i can reply on my own
issue. Therefore i copied the former entered message in this message.
-------------------------------------REPY----------------------------------
Hi Maybe i wasn't clear. I want to dynamically check whether what the
lowest date and the highest date is in the calendar table. The
presented solutions has fixed dates and i don't want that.
If i could store a global variable in SQL server (dynamic properties?)
then it would be great. Fill this once and call it multiple times in
my intensively used function. Is this possible?

issue-----------------------
I have a problem (who not?) with a function which i'm using in a view.
This function is a function which calculates a integer value of a
date. For example: '12/31/2004 00:00:00" becomes 20041231. This is
very handy in a datawarehouse and performes superfast. But here is my
problem.
My calendar table is limited by a couple of years. What happens is
that sometimes a value is loaded which is not in the range of the
Calendardate. What we want to do is when a date is loaded is that this
function insert a minimum date when date < minimum date and a maximum
date when date > maximum date.
Yes i know you're thinking : This is datamanipulation and yes this is
true. But now we loose information in our cubes and reports by inner
joining. So if we can use a minimum and a maximum than a user would
say: "This is strange, a lot of values on 1980/1/1!" instead of "I
think that i have not all the data!"

Hi
If you LEFT or RIGHT JOIN to the calendar table you will get a NULL
value
for the column, you can then is CASE to determine the value
CREATE FUNCTION ConvertDate (@datevalue datetime)
RETURNS INT
AS
BEGIN
DECLARE @dateint INT
SELECT @dateint = CAST( CASE WHEN A.Date < '20030101' THEN '19800101'
WHEN A.Date > '20051231' THEN '99991231'
ELSE CONVERT(CHAR(4),C.[Year]) + RIGHT('0'+
CONVERT(VARCHAR(2),C.[Month]),2) + RIGHT('0'+
CONVERT(VARCHAR(2),C.[Day]),2)
END AS INT )
FROM ( SELECT @datevalue AS [Date] ) A
LEFT JOIN CALENDAR C ON C.[Date] = A.[Date]
RETURN @dateint
END
GO

Hi Hennie,
Is this conversion all that your function does? If so, you might want
to
try the following alternative (using CURRENT_TIMESTAMP as example;
replace
it with your date column / parameter):
SELECT CAST(CONVERT(varchar, CURRENT_TIMESTAMP, 112) AS int)
You could put this in the UDF (probably at least as fast as your
current
Calenmdar-table based function), or use it inline as a replacement to
the
function call (probably even faster).
It should work for all dates from Jan 1st 1753 through Dec 31st 9999.

Create table code ( id identity(1,1) code parentcode internalreference)
There are other columns but I have omitted them for clarity.
The clustered index is on the ID.
There are indexes on the code, parentcode and internalreference columns.
The problem is the table stores a parentcode with an internalreference and around 2000 codes which are children of the parentcode. I realise the table is very badly designed, but the company love orms!!
The table currently holds around 300 millions rows.
The application does the following two queries to find the first internalreference of a code and the last internal refernce of a code:
--Find first internalrefernce SELECT TOP 1 ID, InternalReference FROM code WHERE ParentCode = 'M222' Order By InternalReference
-- Find last ineternalreference SELECT TOP 1 ID, InternalReference FROM code WHERE ParentCode = 'M222' Order By InternalReference DESC
These queries are running for a very long time, only because of the sort. If I run the query without the sort, then they return the results instantly, but obviously this doesn't find the first and last internalreference for a parentCode.
I realize the best way to fix this is to redesign the table, but I cannot do that at this time.
Is there a better way to do this so that two queries which individually run very slowly, can be combined into one that is more efficient?
I have writen a Function which call's the same function it self. I'm getting the error as below.

Hi all, I get this message when trying to update a tabel i have whichhas nested hierarchies.The current hierarchies beginning from root = 1 are up to the level 5.Before going into details and sample data with all the sql queries andprocedures, this limitation from Microsoft for nested levels .. isthere any way or trick to increase the level in generic?
I have created a delete trigger in Table1 and Table2. Once I delete a certain record in Table1 it will also delete that record in Table2 or vice versa. But once i delete certain record either in Table1 or Table2 it will create an error "Maximum stored procedure, function, trigger, or view nesting level exceeded (limit 32).". Can you help me on this?
what I try is a little bit heavy, maybe, but I only miss the minimum/maximum fuction - or I didn´t found it; not here in the Forum and also not in the onlinehelp of the SQL Server.
What I try to do:
I have 2 columns in my table; a start- and an end-date. For this period of time between end and start i have to calculate the days for the years. Here my thoughts (for the current year):
Is the startdate <= 31.12.2004 and the enddate >= 1.1.2004 i have to calculate die datediff between max(1.1.2004/startdate) and min(31.12.2004/enddate)
like this sqlstatement:
SELECT CASE WHEN dbo.Phases.phasenstart <= CAST(CAST(YEAR(GETDATE()) AS varchar) + '-31-12' AS smalldatetime) AND dbo.Phases.phasenabschlussist >= CAST(CAST(YEAR(GETDATE()) AS varchar) + '-01-01' AS smalldatetime) THEN 365 ELSE 0 END AS Expr2, FROM dbo.Phases WHERE (phasenstart IS NOT NULL) AND (phasenabschlussist IS NOT NULL)
instead of 365 there must be the above calculation. Is start=3.1.2003 and end=30.1.2004 I expect as result only the 30 days in 2004.
I am trying to get the minimum and maximum values from a field in SQL Server 2008 Express, but I cannot even get started because I keep getting this error that I cannot figure out.
I have a report that calculates mean, min, max, stddev of somer exercises for a class (pushups, situps, trunk lifts, etc). I also have to calculate those for the 1-mile run time (ex: data -- 7:56, 6:35, 9:45 ( in minuteseconds). Obviously the standard Avg(), Min(), Max(), StdDev() functions won't work for time. So I put in some custom code to convert the time to seconds so I can use the standard functions on the seconds and also code to convert that answer back to minuteseconds. Max() works, but for example when I try to calculate the min(), it includes nulls from the dataset as zeros (not every student has to do the mile run). So the min is always 0. How can I exclude nulls from being calculated. The min() function excludes nulls so it returns the correct min() on integer data. What else can I do?
Hey,First, sorry if this post appear twice, because, I can not find my postrecently send, trying to post it once again.I'm out of ideas, so, I thought, will search help here again :(I'm trying to prepare a view for ext. app. This is in normal cases veryeasy, but what if the view structure should be dynamic?!Here is my point (I will siplify the examples).I have a table:create table t_data (id bigint identity (1,1) not null,valvarchar(10) not null,data varchar(100) not nullconstraint [PK_t_data] primary key clustered(id) with fillfactor = 90 on [PRIMARY] )goinsert into t_data (val, data) values('1111111111','1234567890abcdefghijklmnoprstuvwxyz 1234567890abcdefghijklmnoprstuvwxyz67890abcdefghij klmnoprstuvwxyz')insert into t_data (val, data) values('2222222222','1234567890abcdefghijklmnoprstuvwxyz 1234567890abcdefghijklmnoprstuvwxyz12345abcdefghij klmnoprstuvwxyz')insert into t_data (val, data) values('3333333333','12345abcdefghijklmnoprstuvwxyz12345 67890abcdefghijklmnoprstuvwxyz1234567890abcdefghij klmnoprstuvwxyz')insert into t_data (val, data) values('4444444444','67890abcdefghijklmnoprstuvwxyz12345 67890abcdefg12345hijklmnoprstuvwxyz67890abcdefghij klmnoprstuvwxyz')insert into t_data (val, data) values('5555555555','1230abcdefghijklmnoprst12345uvwxyz1 234567890abcdefghijklmnoprstuvwxyz67890abcdefghijk lmnoprstuvwxyz')gocreate table t_dataVal (id bigint identity (1,1) not null,valvarchar(10) not null,fill varchar(4) not nullconstraint [PK_t_dataVal] primary key clustered(id) with fillfactor = 90 on [PRIMARY] )goinsert into t_dataVal (val, fill) values ('1111111111','AAAA')insert into t_dataVal (val, fill) values ('2222222222','KKKK')insert into t_dataVal (val, fill) values ('3333333333','DDDD')insert into t_dataVal (val, fill) values ('4444444444','ZZZZ')insert into t_dataVal (val, fill) values ('5555555555','CCCC')gocreate table t_conf (id bigint identity (1,1) not null,start int not null,length int not null,description varchar(20) not null,constraint [PK_t_conf] primary key clustered(id) with fillfactor = 90 on [PRIMARY] )goinsert into t_conf (start, length, description) values (1,10,'value_1')insert into t_conf (start, length, description) values (11,3,'value_2')insert into t_conf (start, length, description) values(55,15,'value_3')insert into t_conf (start, length, description) values (33,2,'value_4')insert into t_conf (start, length, description) values (88,1,'value_5')insert into t_conf (start, length, description) values (56,7,'value_6')goNow here is the issue:table t_conf contain data, which can be modified by user.

I have some code I build 2 weeks ago which I’ve been running daily but it’s suddenly stopped working with the following error.
“The table "tbl_Intraday_Tmp" has been created, but its maximum row size exceeds the allowed maximum of 8060 bytes. INSERT or UPDATE to this table will fail if the resulting row exceeds the size limit” When I google this there seems to be a related to tables with vast numbers of columns.
My table tbl_Intraday_tmp is relatively small. It has 7 columns. 1 of varchar(5), 3 of decimal(9,3) and 2 of decimal(18,0). The bit I’m puzzled with is it was working and stopped.
I don’t recall changing anything but I wouldn’t rule that out. I ‘ve inspected the source files and I don’t believe they have changed either.
Dear Experts, i've one database with around 1400 tables. is there any possibilities to know at a time what is the count(*) in each table? actually i need tables which are having maximum data.
my expected result is like this table num_rows table1 20000 table2 10000
like this thank you very much

SELECT * FROM dbo.Objects WHERE (UserRights & dbo.GetUserRights()) > 0)
The purpose of this view is to implement row level security. The Field, UserRights is a BigInt and holds up to 64 bits corresponding to the user or group that has a right to view this record.
The Function GetUserRights() is a function which returns an Int corresponding to the user rights of the person who is currently logged in. In a bitwise fashion, it then "ands" them together to see if the value is greater than 0. If so, the user has rights to the record.
If I hardcode a value to replace the function, the Select statement is very fast. However, if I use the function it is extremely slow. I believe this is due to the function getting run once for each row of the table, instead of just once.
Is there a way to rewrite this so that it only runs once? I could do this in a stored procedure, but I need it in a view so that I can use replace "Objects" (the table) with "vwObjects" the view.

Is there a way in 2005 to script out, directly, a funciton/SP/View or whatever and not have it binary? I used to be able to script something out in 2000 and it would be text and then I could check it into sourcesafe NP and as you know text is much easier to use the compair feature against than binary. Is there a setting in SQL 2005 to handle this? Is it something in Sourcesafe that I need to set?
