Greatest Function In TSQL
Aug 20, 2007
Hi All,
I need to find the highest of two numbers and lowest of the two numbers.
I read on the web that Greatest and least functions in sql can help me do that.
but when i use
greatest in my query it gives me this error
GREATEST is not a recognized built-in function name.
all I have is
declare @first int, @second int
set @first='12'
set @second='14'
select GREATEST(@first,@second)
Can somebody point me in the right direction.
Thanks so much

Hi,
I need some pointers, I am trying to create a SQL function which will check to see if a column in a table will allow null values to be inserted.
I've tried searching the net but to no avail.
Kind Regards

Hey guys,
I have been trying to get a function to work but have been having a hard time. The tables that are used are a translation and validation tables. But the translation can be from different tables. What i would like the function to do is take in a 'description of a type' and a language code and send back the translated version. The issue is that the table is dynamic and there is my issue with my function.
ALTER FUNCTION [dbo].[Trans]
(
@Trans_description AS NVarchar(200),
@languageid AS nvarchar(10)
)
RETURNS nvarchar(50)
AS
BEGIN
DECLARE
@return AS nvarchar(50),
@TABLENAME AS nvarchar(50),
@sql AS nvarchar(100)
set @TableName = (select top(1) listtable from validationType where validationtypeDesc = @Trans_description)
SET @return =
(SELECT TOP (1) ValidationDesc FROM [translationvalidationlist] WHERE validationpartyid IN
(SELECT validationpartyid FROM @TableName WHERE validationtypePartyid IN
(select validationtypepartyid FROM validationtype WHERE validationtypeDesc = @Trans_description
))AND LANGUAGEID = @languageid)
RETURN @return
END
Is there anyway to do a @return = exec(@sql) of course sql would be the current @return. Right now i get the error Must declare the table variable "@TableName".
Thank you so much for all your help.

Hi guys,
I am looking for a solution to the problem described below (SQL SERVER 2000).
Thanks in advance for any help,
Aldo.
The script below:
Code Snippet
SELECT
Data.[Invoice No] AS 'InvoiceNo',
[JurnalTrans.REF2] AS 'JurnalTrans.REF2',
[JurnalTransMoves.SUF] AS 'JurnalTransMoves.SUF',
[RowIDDataLevel] AS 'RowIDDataLevel',
CASE WHEN RowIDDataLevel = 1 THEN CAST(Paid AS int) ELSE '0' END AS 'Paid' ,
CASE WHEN RowIDDataLevel = 1 THEN CAST([JurnalTransMoves.SUF] - [Paid] AS int) ELSE '0' END AS 'OutstandingBalance'
FROM CTE AS Data
INNER JOIN (SELECT [Invoice No], SUM([JurnalTransMoves.SUF]) AS Paid FROM CTE GROUP BY [Invoice No]) AS SUMSUF ON SUMSUF.[Invoice No] = DATA.[Invoice No]
ORDER BY [Accounts.ACCOUNTKEY], Data.[Invoice No], [RowIDDataLevel]
Gives these results:
Invoice No JurnalTrans.REF2 JurnalTransMoves.SUF RowIDDataLevel Paid OutstandingBalance
----------- ---------------- ---------------------- -------------- ----------- ------------------
5752 NULL 1155 1 1810 -655
5752 2032 400 2 0 0
5752 2033 155 3 0 0
5752 2034 100 4 0 0
5754 NULL 1732.5 1 2482 -750
5754 2035 750 2 0 0
16687 NULL 2555.8 1 2555 0
Where:
1810 (Paid) = 1155 + 400 + 155 + 100
2482 = 1732 + 750
and so on...
What I need is to get:
instead of 1810 ==> 655 = 400 + 155 + 100
instead of 2482 ==> 750
and so on...
In order to do that, I tried inserting "WHERE RowIDDataLevel Not In (1) " in the line:
Code Snippet
INNER JOIN (SELECT [Invoice No], SUM([JurnalTransMoves.SUF]) AS Paid FROM CTE WHERE RowIDDataLevel Not In (1) GROUP BY [Invoice No]) AS SUMSUF ON SUMSUF.[Invoice No] = DATA.[Invoice No]
and then getting the following:
InvoiceNo JurnalTrans.REF2 JurnalTransMoves.SUF RowIDDataLevel Paid OutstandingBalance
----------- ---------------- ---------------------- -------------- ----------- ------------------
5752 NULL 1155 1 655 500
5752 2032 400 2 0 0
5752 2033 155 3 0 0
5752 2034 100 4 0 0
5754 NULL 1732.5 1 750 982
5754 2035 750 2 0 0
That it is almost what I need, but not good enough because it makes the line marked in red to disappear because of RowIDDataLevel =1
16687 NULL 2555.8 1 2555 0
to disappear.

Hi guys,
I am using the LIKE function combined with a CASE WHEN to change a long list of words, but the list is too long...
Is there any posibility to insert more than one argument into one like function...?
Any other good ideas?
Below an example of the code I am using..
Thanks in advance,
Aldo.
Code Snippet
Case
WHEN JurnalTrans.DESCRIPTION LIKE '%myArgument01%' THEN 'Result'
WHEN JurnalTrans.DESCRIPTION LIKE '%myArgument02%' THEN 'Result'
WHEN JurnalTrans.DESCRIPTION LIKE '%myArgument03%' THEN 'Result'
WHEN JurnalTrans.DESCRIPTION LIKE '%myArgument04%' THEN 'Result'
ELSE ''
END AS 'Result'

Hi all. I'm looking for assistance to get the greatest value from 3 or more different columns. I'm assuming that the best way is to put the columns into a temp table and use 'max' function to return the greatest value but don't know how to code it. Thanks in advance.

1.I am trying to write following query in SQLserver(this is oracle query),
IS their any equivalent for GREATEST and LEAST functions in SQLServer ???
Update mwebtemp
Set Temp_amount1 = (SELECT SUM(AuthAttr_Amount*(num_Business_Days
(GREATEST(AuthAttr_Start_Date, @dtstartdate),
LEAST(AuthAttr_Finish_Date, @dtenddate))))
.....where...
etc...
.....
Note: this is part of a stored procedure...
2. Also how do you write and call a function in SQLServer (syntax ??), eg.num_Business_Days
is a function returning number of business days between the 2 dates....

I have to to find the greatest and least values from the set of values which are from the different columns.
Eg. Select greatest(tab1.date1, tab2.date2), least(tab1.date3, tab2.date4)
from tab1, tab2
where....
tab1 and tab2 are the tables and
date1, date3 are the columns from tab1
date2, date4 are the columns from tab2
Is there any easy way to do this in SQL server ?
MAX and MIN will not work here as these are not the max and min from the same column they are from the different tables and columns.
Thanks

Hello,
Here's one way to sum only the top 5 (greatest 5) values per group.
I assume there is a table called IdValues that contains two columns: id int, value int.
declare @lastId int
declare @value int
declare @count int
declare @idList varchar(5000)
declare @valuelist varchar(5000)
set @count=0
set @lastId = -1
set @value = 0
set @idList=''
set @valuelist=''
select
@count=(case when @lastId<>id then 1 else @count+1 end),
@value=(case when @lastId<>id then value when @count<=5 then @value+value else @value end),
@idList=(case when @lastId<>id then cast(id as varchar)+','+@idList else @idList end),
@valuelist=(case when @lastId<>id then cast(@value as varchar)+','+@valuelist else cast(@value as varchar)+','+right(@valuelist,len(@valuelist)-charindex(',',@valuelist)) end),
@lastId=id
from IdValues
order by id desc, value desc
select @idList,@valuelist
It's a funny approach. I'd be interested to see a better method. In MySQL it is possible to do this much better and have it produce an actual resultset (since MySQL allows you to assign variables and product a resultset in the same query).
I also noticed something interesting. If you do any operation on the order-by columns, the query doesn't work. For example, if I do:
order by id+0 desc, value desc
something funny happens and you only get one id and one value in the list variables. Maybe someone else who actually some idea of how SQL Server works can explain this.
Thanks,
Thomas

What happens when autoincrement reaches its last value? Does my application crash? Will autoincrement wrap?
Let us assume I figure that my database table will be much smaller than 2^16 records. Since it will be nowhere near the limit, I select smallint (2 bytes wide) as my ID field. I set the seed value to -32,767. I set the increment value to 1. Over the course of actual useage, many records are added and deleted many times. Although I correctly anticipated that the number of records in my database is far less than 65,535, autoincrement has reached 65,535. What will happen next? Ideally I would like autoincrement to wrap and take the next unused value. But does it do that? Or does it freeze at the highest value? What happens?

And the "dbo.AuthorsForState" is in the Table-valued Functions, Programmabilty, pubs Database.
I tried to get the result out of the "dbo.AuthorsForState" by executing the following sql script:
shcInlineTableFNresult.sql:
USE pubs
GO
SELECT * FROM shcInLineTableFN

I got the following error message:
Msg 208, Level 16, State 1, Line 1
Invalid object name 'shcInLineTableFN'.
Please help and advise me how to fix the syntax
"SELECT * FROM shcInLineTableFN"

I need to be able to pass the output of a function to another function as input, where all functions involved are user-defined in-line table-valued functions. I already posted this on Stack Exchange, so here is a link to the relevant code: [URL] ...
I am fairly certain OUTER APPLY is the core answer here; there's *clearly* some way in which does *not* do what I need, or I would not get the null output you see in the link, but it seems clear that there should be a way to fool it into working.

Hello Friends, I am not sure if this is the right place to post this question but if not please suggest me when it can be posted.
I have been thinking of writing Stored procs in SQL CLR/ changing all of my Stored Procs to SQL CLR.
Is there any thing that I need to keep in mind about the size of the sotred proc (like calculation intensive) before I do that? I mean can even change a TSQL stored proc which is relatively small Stored Proc, that simply said Select * from Customers to SQL CLR? or the SQL CLR does only useful/makes difference with calculation intensive stored procs and big stored procs?
When I talked to our Architects they said every small sized stored proc can be written using SQL CLR and more over forget about the classic TSQL stored procs and get used to write SQL CLR when ever writing any database related stuff.
And also there are so many articles that discussed about the advantages of SQL CLR over the TSQL but I would appreciate if some one could put few bulletted points why do you think SQL CLR is more powerful.
Please advise.Thanks in advance,-L

Hi
I am creating some dynamic sql by passing variouse parametrs to my Stored Procedure. One of my Parameters is string has lots of values seperated by a comma to help build an 'IN' statement.
SET @SQL = 'SELECT * FROM areas'SET @p1 = '10,20'If @p1 IS NOT NULLBEGINSET @sSQL = @sSQL + ' WHERE (Areas IN (''' + Replace(@p1,',',''',''') + '''))'END
The above query runs perfecly well in Query Analyser, however when I put it into my ASP.NET application I get an error of "Error converting data type varchar to numeric."
So I think I need to do some sort of casting or Converting but im not sure how to do it. Or do I need to use a INSTRING?
I did manage to work out a method by using the follwoing
SELECT * FROM Areas WHERE PATINDEX('%,' + CAST(ArType AS VARCHAR) + ',%',',' + @p1 + ',') > 0
But I cant seem to convert the above line into coherent dynamic statement. My feeble attempt is below but I keep getting errors
SET @sql = @sql + ' WHERE PATINDEX(''%,'' + CAST(ArType AS VARCHAR) + '',%'','','' + @p1 + '','') > 0'
IM strugging to understand all the '''. My TSQL is pretty basic, any help would be much appreciated
Many thanks in advance

Sql Server 7.0
==============
Hi all!
To find out the duplicate entries in a particular column,
I used the following tsql
select pno ,count(pno) from table1 group by pno
having count(pno)>1
But now I have another case where i have to test duplicity as a combination of 3 columns.
ie, for Eg :I have 3 columns with the following values.
colA colB colC
1 2 3===============row 1
1 3 5===============row 2
1 2 3===============row 3
1 4 5===============row 4
8 9 0===============row 5
I want to pick up all the duplicate rows(combo of colA,colB,colC)
duplicate rows here would be row 1 and row 3.
Can somebody give me a clue as to how to achieve this via TSQL.
Any help greatly appreciated.
TIA
