Help Me Write A Search Function Please
Jun 8, 2007Hi all,I'm very new to ASP.NET stuffs, I'm trying to write a Search function for my website... I have two text boxes, one if called "SongTitle" and the other is "Artist"... Now I need to populate the GridView to display the result, based on the input of the textbox... So if only the "SongTitle" have input, it will search for the Song Titles on the database... if the Artist is searched, then it will return the artist... If both text boxes have value in them, then it need to check for both fields in the database and return the correct item... For the "Artist", I have 2 columns in the Database (originalArtist and performer), so for the Artist select statement, it need to check both columns on the table, if any of them match then it will return the item. Any help would be greatly appreciated,Thank you all,Kenny.

How Do I Write An OUTER APPLY Without A Table Function?
Nov 1, 2006I'd like to select the last unshipped order, or if none is open, the last shipped order, for each customer. I noticed that all the examples on line for OUTER APPLY involve table-valued functions, but I have read (in a book I don't have here) that a subquery can work. The following shows what I want, but it isn't valid syntax:
SELECT c.CustomerName, oa.OrderNumber, oa.Status
FROM Customers c
OUTER APPLY (
SELECT TOP 1 CustomerID, OrderNumber,
CASE WHEN ShipDate IS NULL
THEN 'due ' + CAST(DueDate AS VARCHAR)
ELSE 'shipped ' + CAST(ShipDate AS VARCHAR)
END AS Status,
CASE WHEN ShipDate IS NULL
THEN DueDate + 1000 -- Give open orders priority.
ELSE ShipDate
END AS SortOrder
ORDER BY SortOrder
) AS oa ON oa.CustomerID = c.CustomerID
How To Write A Function With Integer Parameter Accepting Null
Jan 19, 2007I've got a function which inserts into a database, and has arguments for each item being inserted
A couple of the items are integer datatypes (in SQL), but they will accept nulls
When I add my parameters, it asks to explicitly use the SQL datatype (which is integer):.Add("@myParam", SqlDbType.Int).Value = myParam
In the header of the function, I assumed I could make the argument optional - Optional ByVal myParam as Integer=System.DBNull.Value
However, when the function runs, I always get an error:System.InvalidCastException was unhandled by user code Message="Conversion from type 'DBNull' to type 'Integer' is not valid."
I make them all Optional (which won't happen, but various arguments may be, at different timesand I get this error, with the last item (which is on a separate line), in red:Constant expression is required.
How can I get around this?
How To Write A Function That Will Return True If User Is In A Certain Role?
Jul 20, 2005I have a SQL database with an Access front end. In the database Ihave a read only and a read write role. When a read only user opensthe database I want all the fields on the form to be locked so thatthe user will not try to change data and get an error from the server.Right now I am doing that with a table. But it's a hassle to have tomaintain a table when if I could answer the question is the currentlylogged in user in the read write role?My server is running SQL Server 2000. So I was wondering if I couldwrite a function to do this? The function would take the role beingchecked as a text parameter and return true if the currently logged inuser is in that role or false if he/she isn't.

Pass Output Of A Function To Another Function As Input

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.

Using A Scalar Valued Function As A Parameter Of A Table Valued Function?
Feb 1, 2006Ok, I'm pretty knowledgable about T-SQL, but I've hit something that seems should work, but just doesn't...
I'm writing a stored procedure that needs to use the primary key fields of a table that is being passed to me so that I can generate what will most likely be a dynamically generated SQL statement and then execute it.
So the first thing I do, is I need to grab the primary key fields of the table. I'd rather not go down to the base system tables since we may (hopefully) upgrade this one SQL 2000 machine to 2005 fairly soon, so I poke around, and find sp_pkeys in the master table. Great. I pass in the table name, and sure enough, it comes back with a record set, 1 row per column. That's exactly what I need.
Umm... This is the part where I'm at a loss. The stored procedure outputs the resultset as a resultset (Not as an output param). Now I want to use that list in my stored procedure, thinking that if the base tables change, Microsoft will change the stored procedure accordingly, so even after a version upgrade my stuff SHOULD still work. But... How do I use the resultset from the stored procedure? You can't reference it like a table-valued function, nor can you 'capture' the resultset for use using the syntax like:
DECLARE @table table@table=EXEC sp_pkeys MyTable
That of course just returns you the RETURN_VALUE instead of the resultset it output. Ugh. Ok, so I finally decide to just bite the bullet, and I grab the code from sp_pkeys and make my own little function called fn_pkeys. Since I might also want to be able to 'force' the primary keys (Maybe the table doesn't really have one, but logically it does), I decide it'll pass back a comma-delimited varchar of columns that make up the primary key. Ok, I test it and it works great.
Now, I'm happily going along and building my routine, and realize, hey, I don't really want that in a comma-delimited varchar, I want to use it in one of my queries, and I have this nice little table-valued function I call split, that takes a comma-delimited varchar, and returns a table... So I preceed to try it out...
SELECT *FROM Split(fn_pkeys('MyTable'),DEFAULT)
Syntax Error. Ugh. Eventually, I even try:
SELECT *FROM Split(substring('abc,def',2,6),DEFAULT)
Syntax Error.
Hmm...What am I doing wrong here, or can't you use a scalar-valued function as a parameter into a table-valued function?
SELECT *FROM Split('bc,def',DEFAULT) works just fine.
So my questions are:
Is there any way to programmatically capture a resultset that is being output from a stored procedure for use in the stored procedure that called it?
Is there any way to pass a scalar-valued function as a parameter into a table-valued function?
Oh, this works as well as a work around, but I'm more interested in if there is a way without having to workaround:
DECLARE @tmp varchar(8000)
SET @tmp=(SELECT dbo.fn_pkeys('MyTable'))
SELECT *
FROM Split(@tmp,DEFAULT)

Hot To Write This SP
May 9, 2002Hey all.. Sorry I have never written a SP in my life.
so this would be a newbie question for sure.
Using sql server 7.
Here is my table field setup with sample values all fields are numeric
except date
weekending size effic dailycap workdays planutil demand
variance
5/172002 8 80 85 5 244
102 142
A file with source data will be made available in comma delimitted format to
supply a new weekending value, size and demand.
What I will need is first the dts to bring that in. then I am assuming a
stored procedure to be run (this is why I am here)
to add the data from the comma del. file into the table. If the data EXISTS
I would want it to UPDATE the values that are in the dest table but run a
calculation first which would be the planutil minus demand then the result to
be updated intot the record.
if the record from the tab del. file does not exisst in the dest table then
insert it.
another words the logic i have in mind
read the data from the temp tample (where the file gets imported into)
see if the record exists in the live table is it does update it with the calculation of planutil minus demand
if not create the new record in the live table.
I need it to compare..
Someone help me with some code
i thank you kindly in advance
p.s. And good books dedicated to stored procedures??
Help To Write A Qry
Dec 1, 2006Many thanks in advance for anyone that can help me write this qry:
To summarise - we have a database that links components to services. Components can have a 1 to many relationship with services. The components are held in a table:
dbo.components
compID compName compType
1 srv1 1
2 srv2 1
3 srv3 1
We also have a services table which hold all our various services we own:
dbo.services
svcID svcName
1052 svc1
1053 svc2
1054 svc3
We then have a tbl that shows the links between components and services
dbo.compUses
svcID compID
1052 310
1052 400
1053 122
1256 134
I would like to find out through the qry what components are currently NOT linked to a service. This will allow me to find out what components have no relationships.
This is in SQL2005.
Have I explained this well enough? Any help would be much appreciated!
