It is possible to have constraints other than primary key or null constraints. Have you checked indexes on the table, or other constraints. I'm rusty on my Oracle, but every other database I've used lately has an option to temporarily disable constraint checking for data loads.

Can anyone tell me how to write a sql query to get a comma separated list of values.
Eg.
IF the table ColorTable contains in it's colors field red,blue and green.
The query "Select colors from ColorTable" would return 3 rows with each row containing each color.
I would like to have a query that would return the colors in one row as red,blue,green instead of returning 3 rows
I tried using list(colors) but this function is not recognised.
Kindly help me,
Thanks in advance

select (<br />
(select description from colortable where description='green') + ',' + <br />
(select description from colortable where description='Blue') + ','+ <br />
(select description from colortable where description='Red')<br />
) as colors from colortable
|
|
|
|
|
Is there any other way without hard coding the values and individually concatenating them as I have to retrieve data from a table with numerous records based on some conditions.
|

You can do something like this:
<br />
<br />
declare @list varchar(1000)<br />
<br />
select @list = isnull(@list, '') + colors + ',' from ColorTable<br />
<br />
select @list<br />
<br />
It's got some extra "features" like that it always ends in a comma, but for every issue you may have with it there's a reasonable solution. Ask if you need more help with that.

That was just what i needed.
Thanks a lot.
By using the following i have removed the comma that appears at the end of the line
select substring(@list,1,len(@list)-1)
Now can you please tell me if there is a way in which the comma before the last item can be replaced with 'or'
i.e. I would like the output to be like
red,blue,green,..........pink or yellow

Sure, try this:
<br />
declare @list varchar(1000)<br />
declare @len int<br />
<br />
select @list = isnull(@list, '') + colors + ',', @len = len(colors) from ColorTable<br />
<br />
select @list = substring(@list, 1, len(@list)-1)<br />
select substring(@list, 1, len(@list) - @len - 1) + " or " + substring(@list, len(@list) - @len, @len)<br />
I'm not in front of a SQL Server right now so I can't try it easily, and I may be off by a character (and thus a -1 or +1 in the substring lengths) here and there. I'm sure you can figure out the tweaks, though.
The concept is to have a variable hold the length of the last element. It does this by constantly replacing its value with the length of the current element; at the end of the query, it will contain the length of the last element. Once you know that, it's a matter of string handling to cut your list up and replace text as necessary.
Two more things:
1. If there's a possibility that ColorTable may contain zero, one or two rows, or if you're using a where clause that may return only zero, one or two rows, you may want either some if/then or case when clauses with select count statements to ensure you don't return errors.
2. While it's possible to do this in SQL, as demonstrated, there are some things that are better left to code. I assume you have a really good reason for doing it on the SQL Server instead of in whatever language you're using for your queries, but in general I'd recommend this be done in a code library instead of on the DB server.

Hello Friends,
May be I am missing some thing here while trying to build a dynamic WHERE clause.
this is the final version of my Stored pror
set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER PROCEDURE [dbo].[USP_SearchVehicleOnYMM]
@Year char(4)
,@Make int
,@Model int
AS
BEGIN
SET NOCOUNT ON;
IF LEN(@Year)<=0
begin
select @Year = NULL
end
IF LEN(@Make)<=0
begin
select @Make = NULL
end
IF LEN(@Model)<=0
begin
select @Model = NULL
end
SELECT V.vin
,C.FirstName
,C.LastName
,C.AccountNum
,D.DealerShipName
,Contrt.MaturityDate
,VS.GroundedDate
,V.[Year]
,VMkL.VehicleMakeDesc
,VMdL.ModelDesc
FROM Vehicle V
Inner Join ContractInfo contrt ON Contrt.VehicleID = V.VehicleID
Left Join DealerShips D ON v.ManufacturerID = D.ManufacturerID
Inner Join Customer C ON Contrt.CustomerID = C.CustomerID
Inner Join VehicleStatus VS ON Contrt.VehicleID = VS.VehicleID
Left Join ManufacturerMakeModel mmm ON v.MakeID = mmm.makeID
left Join VehicleMakeLookUp vmkl ON mmm.MakeID =
vmkl.VehicleMakeID
left Join VehicleModelLookup VMdl ON mmm.ModelID =
VMdl.ModelID
WHERE
((@Year IS NULL ) OR (V.Year=@Year))
and
(( @make = 0 ) OR (VMkL.VehicleMakeDesc=@make))
and
(( @Model = 0 ) OR (VMdL.ModelDesc=@Model))
END
And when I exectue (right click on the stored proc in management studio
and pick the exectue option) this with out providing any values to the
Year, Make and Model I am getting this error
**********************************Error*****************************************************
Msg 201, Level 16, State 4, Procedure USP_SearchVehicleOnYMM, Line 0
Procedure or Function 'USP_SearchVehicleOnYMM' expects parameter
'@Year', which was not supplied.
(1 row(s) affected)
***************************************************************************************************
Could some one please fix this error and have me understand where I am doing wrong?
Thanks

GetDate() will return the current date and time. It is easy enough to just get the time portion from the returned DateTime

Encrypt the password first and then save it in the database like anything else.

As I already said "Encrypt the password first" then put it in SQL. You cannot encrypt it in SQL without using extended stored procedures in SQL Server 2000 or using CLR stored procedures in SQL Server 2005. Either which way the encryption process does not happen in SQL code.
