The following code uses a WHILE loop to Insert a row in table2 with every ClientID in table1 and every consecutive Year between 2000 and 2010. It works, but it is slow when table 1 is large, say 100,000 records.DECLARE @MyYear smallintSET @MyYear = 2000WHILE @MyYear <= 2010 -- i.e., for each year from 2000 to 2010BEGININSERT INTO table2 (Year, ClientID) SELECT @MyYear, table1.ClientID FROM table1SET @MyYear = @MyYear + 1ENDIs there any way to speed this up by using just an INSERT statement such as:INSERT INTO table2 (Year, ClientID) SELECT <years from 2000 to 2010>, table1.ClientID FROM table1Where the expression <years from 2000 to 2010> increments the Year value?Thanks

Scalar function help-New to tsql
Hi all,Firstly many apologies if this is in the wrong place. I'm basicly trying to create a scalar function that returns a nvarchar (15) variable.The Function has two input variables namely [category] and [AreaCode] (both nvarchar(15)) with an output variable [Team Line]. I've constructed this without any problem via a case statement (see below), but as I need to use this statement repeatingly I thought a scalar function would be the answer!I'm new to sql functions so any good advice would be much appreciated!select,case when when [Category]='A' then 'Team A'when [Category]='B' then 'Team B'when [Category]='C' then 'Team C'when [Category]='K' and [AreaCode] in ('Acct','Desp','Analysis') then 'Team D'when [Category]='L' and [AreaCode] not in ('Lark') then 'Team E'else 'Others'end as [Team Line]Kindest regards,J

ISNULL results
Hi there, I have two super queries below that go off and for a 'Job Ref' pulls back the 'Number of Appointments' and another one that pulls back the 'Number of times a job is Carded'As it is a LEFT OUTER JOIN I still get results if the result is a NULL value. What I want to do is for a NULL value is return a '0' instead. The reason for doing this is later on in the script I want to do a calculation that takes away [b]''Number Times Carded' [/b]from the [b]'Number of Appointments' [/b]. If either the colums are Null it messes up my figures as the result will come back as Null.So I'm using COALESCE in my sub queries but not sure I'm doing it right as I'm still getting Nulls in my results.[code="sql"]SELECT DISTINCT job.[ref] AS 'Job Ref' , APP.APPOINT AS 'Number of Appointments' , CARDED.Carded AS 'Number Times Carded' FROM dbo.Job AS JOB LEFT OUTER JOIN (SELECT JOB_ID, COUNT(COALESCE(JOB_ID,'0')) AS 'Carded' FROM [dbo].[JobEvent] WHERE Description LIKE '%Carded%' AND EVENT = 'Additional Appointment Required' GROUP BY job_id ) AS CARDED ON JOB.ID = CARDED.job_id LEFT OUTER JOIN (SELECT job_id, COUNT(COALESCE(job_id,'0')) AS 'APPOINT' FROM Appointment WHERE status = 'Complete' GROUP BY job_id ) AS APP ON JOB.ID = APP.job_id WHERE (JOB.status_id NOT IN ('0', '5', '6', '1', '2')) AND (JOB.actual_enddate >= CONVERT(DATETIME, '2013-04-01 00:00:00', 102)) AND (JOB.actual_enddate <= CONVERT(DATETIME, '2014-03-31 00:00:00', 102)) [/code]

how to combine more than one SET operator correctly, to solve problem
It's come to my attention, from taking SQL Server 2012 practice tests, that I don't know how to combine SET operators UNION, INTERSECT, AND EXCEPT for situations requiring more than one type to solve a problem.I would like to understand before it turns into [i]real life.[/i]Practice question:The Hovercraft database has three tables related to Hovercraft design, OldDesign, CurrentDesign, and FutureDesign. Some designs are present in more than one table. You want to generate a list of all items in the FutureDesign table as well as FutureDesign items that are present in both the OldDesign and CurrentDesign tables.Answer:SELECT HovercraftModelID, Name FROM Hovercraft.OldDesign INTERSECT SELECT HovercraftModelID, Name FROM Hovercraft.CurrentDesign UNION SELECT HovercraftModelID, Name FROM Hovercraft.FutureDesignIn the case of my DDL, it's the color red, plus black and white, that should be returned....and it does that using same semantics. [code="plain"]create table oldColors(color varchar(20));insert into oldColorsvalues('red'),('pink'),('pale blue'),('light yellow');create table currentColors(color varchar(20));insert into currentColorsvalues('red'),('blue'),('salycilic yellow');create table futureColors(color varchar(20));insert into futureColorsvalues('black'),('white'),('red'); SELECT color FROM oldColors INTERSECT SELECT color FROM currentColors UNION SELECT color FROM futureColors;[/code]My confusion: But, to me the correct answer reads like its going to retrieve only the designs that OldDesign has in common with CurrentDesign and all the designs in FutureDesign. But when I run the set operation it does what is asked.Is this a situation of 'White Panda Eats Shoots and Leaves'? which could be interpreted differently depending on how you read it IE. that I'm just reading the set operation with the wrong mindset?Can anyone relate to my confusion and help me out of it?

Temp tables vs "permanent" temp table vs User Table Type
Hi,We have an SP that receives an XML field with loads of data (sometime it has over 1.000 records).The XML data is used in the SP and other SPs called from the "main" SP and used to join with other tables.What's the best way to store the XML? 1. A #temp table knowing it will always be created and dropped not taking advantage of statistics (can have PK and IDX to improve the joins);2. A permanent temp table, this is, a table created like all the others but the data is inserted and deleted, just for processing porpoise, and the key has a SessionId. This can take advantage of statistics and the table isn't created and dropped whenever the SP is called;3. A user defined table variable to be used as parameter (can have the PK to improve joins).If the software was made in c#, that can use the UDT type, i'd probably go with it but since it's VB6 it doesn't support UDT types so the data has to passed as one big XML chunk.Thanks,Pedro
