Try using case statements instead?
...
CASE WHEN Q.QueueId= 'Pass Validation' THEN 1 ELSE 0 END AS 'PassedVerifier',
CASE WHEN A.fundingMethodId = 'Cash' and Q.QueueId= 'Pass Validation' THEN 1 ELSE 0 END AS 'CashFunded',
...

I'm trying to allow control over events/records displayed on a calendar using checkboxes.
Here is what I currently have:
http://propeller.head.home.comcast.net/~propeller.head/page1.html
It's just your run-of-the-mill asp calendar with some added AJAX so that when you mouse-over the date's, it displays the list of events for that day.
What I am attempting to add is the ability to control the SELECT (or display) of events by way of some checkboxes. Something that looks like this:
http://propeller.head.home.comcast.net/~propeller.head/page2.html
But im confused about how to update/change SELECT statements on the fly - or if it's possible... Any hints, pointers, samples?
Here is the calendar script:
http://propeller.head.home.comcast.net/~propeller.head/new/calendar.txt
Here's my AJAX event:
http://propeller.head.home.comcast.net/~propeller.head/new/ajaxevent.txt
Thanks!

I am creating a user defined type for time only. I have a book called pro sql server 2005 database design and optimization that has the code to create an assembly to create a user defined type for date only, but I need to create one for time only.
Does anyone know what the difference is between creating a UDT for date vs. time?
Has anyone here ever created one before that works?
Do you have the code?
I read somewhere that sql server 2008 has a time only type included in it. Does anyone know if there is a way to get the code that microsoft used to create the assembly in 2008 for the time only data type?

This is probably a permissions issue. Check that you have the appropriate permissions to execute the updates. BTW, you could probably rewrite your code without using cursors.

Hello All,
Our server poopped the bed and we got it back to crawling slowly. We had some small but slightly important databases on the server which we are trying to reattach. We keep receiving an error indicating the log file is corrupted in some manner, therefore we are trying to reattach the mdf file without the ldf. Again we are running into issues.
Has anyone ever successfully reattached a database without the LDF file?
Any responses will be greatly appreciated.

The way SQL Server works is that when you make a change to the database, the operation is immediately logged to the log file. It then makes the changes to the in-memory copy of the data, but does not immediately flush those changes back to the data file. It only does so when it needs to flush data out to reuse the buffer space, on idle, and when a checkpoint operation occurs. The checkpoint operation basically synchronizes the data and log, and is done frequently enough that the configured recovery interval can be achieved, that is, the time to recover from a system failure assuming that the data and log files are intact. The default recover interval is one minute, that is, a recovery should take around one minute to complete.
(In practice the log is also buffered to allow multiple log records to be written out in one operation. However, when you commit a transaction, the log records relating to that transaction have to be completely written to disk before SQL Server will proceed with the following statement or return to the client.)
The upshot of this lazy writing is that the data file may not be transactionally consistent. In fact, it probably isn't. Your best bet is to restore from a known-good backup - you will of course lose the operations that took place after the backup was made.
I'm not sure if you can reattach this database. What you probably should have done is run DBCC CHECKDB with one of the REPAIR options. You may be able to attach using CREATE DATABASE ... FOR ATTACH_REBUILD_LOG on SQL Server 2005; for SQL Server 2000 try sp_attach_db.
For the future, if you're not already doing so: it's considered best practice to keep your transaction logs on a separate disk (array) from the data, so that a failed data volume doesn't cause you to lose your transaction logs as well - remember that if you have logs but no data file you can back up the logs, restore a full database backup then restore the log backup to recover to the point of failure. In addition you can get some performance benefit because the disk head is typically over the place that the next block of log records need to be written - disk latency is governed by head seek time. If you plan to use RAID to protect your logs, go with RAID 1, mirroring - there is no benefit from striping (the writes are sequential and would simply target each disk in turn) and RAID 5 hurts write performance.

I know MS-SQL can connect to other databases to communicate to them with Linked Servers. Does anyone know if Sybase can do this? If so, how is this accomplished? Thank you in advance.

Hi,
I have an sp name Movie_SP which returns all the movies by taking MovieName
Now in my New sp(Search_Movies_SP) I want to use the out put of the first SP(Movie_SP)
and with the result of Movie_SP I have to manipulate
Actually I need to set priorities as my first SP Movie_SP is returning all the movies with say BLACK in an Improper way
I want to make it to a order where Black comes First,
then The Movies which starts with Black second,
and the third is The Movies which contains Black
Plz help me
thanks
Pashi

Could've been better if you have mentioned which database you are working with.Assuming that you are working with Sql Server...
pashitech wrote: use the out put of the first SP
Are you looking out for something like an Output Parameter[^]?
If no (which I assume so), I guess you'll have to populate the data onto a temporary table for manipulations.
pashitech wrote: make it to a order
You may try using the LIKE[^]operator.
Select * from tblMovies where MovieName = 'Black'
The above query fetches you details where the movie name is black (an exact match)
Select * from tblMovies where MovieName Like 'Black%'
The above query gives you details where the movie name begins with black (including black)
Select * from tblMovies where MovieName like '%Black%'
This one fetches movie names that contain the word black.
-- For better usage with the like operator, refer to the URL linked.

|
|
|
|
How about:
create table #temp1 (
--list of columns returned by Movie_SP goes here
)
insert into #temp1
exec Movie_SP @Param1, Param2, ...
select * from #temp1
order by case
when Title = 'Black' then 'A'
when Title LIKE 'Black %' then 'B'
else 'C'
end,
Title
You can use "insert into" to return the resultset of a stored procedure into a temporary table. The following select statement uses a case statement to prioritorise the ordering. You might need to tweak this a bit because I didn't quite understand your requirements.

Andy

I need to create a User Defined Type for time. I tried rewriting my database tables as shown below and I get the error that is shown below.
Do I need to do something else to create them? Do I need to use hh:mm for the formatting of the datapart I need to use?
All I need in ts_from and ts_to is the hour and the minutes.
I am using SQL Server Express 2005.
create table tbl_teach_sched (<br />
ts_id int NOT NULL IDENTITY(1000,1),<br />
teach_id int,<br />
ts_day text,<br />
ts_datetime datetime,<br />
ts_from as (datepart(hh:mm, ts_datetime)) persisted,<br />
ts_to as (datepart(hh:mm, ts_datetime)) persisted,<br />
primary key(ts_id),<br />
foreign key(teach_id) references tbl_teachers(teach_id));
This is the error.
Msg 102, Level 15, State 1, Line 7
Incorrect syntax near 'hh:'.
Msg 132, Level 15, State 1, Line 8
The label 'hh' has already been declared. Label names must be unique within a query batch or stored procedure.
|
|
|
|

Yeah, you can't do that.
Either just use the DateTime, or use a smallint.
The smallint could be the number of minutes or seconds from midnight, or it could be hours*100+minutes.
But I spend so much time converting between time-storage schemes that I prefer DateTime; the savings in maintenance makes up for the waste of space.
|
|
|
|
|
I have a book taht suggests creating a user defined data type for time only? How is it that I can't create a user defined type for time alone?

I have Googled without success (I keep getting blog posts that deride Access/Jet SQL as 'sucking'* with a comment feature at the bottom of the page), but does anybody know how to code-comment Access/Jet SQL?
I'm attempting to show our resident VB "whiz" how he's left himself open to SQL Injection attacks - when his application targets SQL Server I can successfully hack his code in the manner described by various posts/articles by injecting my own SQL and by commenting out his, but in Access/Jet SQL it doesn't appear to work.
*Yes, I'm inclined to agree with the majority of these posts.

Hi,
I am new in the field of databases.
I am trying to create a strong typed dataset (using vs 2005 add data set wizard).
The table in my data base include foreign keys (relations).
When the wizard finishes the dataset is created with all the necessary tables and fields, EXCEPT for data relations.
When I am performing the same thing with access data base the relations are loaded well.
Does anyone have an idea of what it could be.
Sincerely yours
Y.R.

how would I select and count the number of values that match: j0107_a131 and show the following two values
j0107_a131
j0107_a131_01
the roomcode is in a string that is why i specified below 'like roomcode'
i.e. select count (room_code) from rooms where room_code like room_code
hope that makes sense cheers

Well, you could always do this:
select @room_code = @room_code + '%'
select count(room_code) from rooms where room_code like @room_code

i am using ASP.net, C# anD SQL Server2005,in the following query:
string q = "SELECT collapsed_building.b_name,collapsed_building.b_desc FROM collapsed_building WHERE collapsed_building.b_name LIKE '" + crimewithdate.text2 + "' ";
I WANT TO USE % AFTER THE KEYWORD like SO THAT ALL THE BUILDING NAMES WHICH MATCH THE VALUE ENTERED BY THE USER ARE DISPLAYED
WHEN I WRITE (LIKE '" + %crimewithdate.text2 %+ "'), IT GIVES ERROR, WHAT WILL BE THE CORRECT SENTAX

Please, don't do this. You leave yourself with open to a Sql Injection attack. Take a look at this[^] article on how to avoid this. Now, you many want to consider using something like this:
DECLARE @building_name NVARCHAR(100)
SELECT @building_name = 'Test'
-- The lines above are just a sample to get you started. Move this into a stored procedure and use
-- the code below to do the actual work. Note that you would want to determine whether or not
-- @building_name ended in a % before using this code.
SELECT @building_name = @building_name + '%'
SELECT collapsed_building.b_name,collapsed_building.b_desc FROM collapsed_building WHERE collapsed_building.b_name LIKE @building_name

Pete is correct in saying that this is dangerous code. You have to use strong
protection to make sure that crimewithdate.text2 does not contain
any malicious SQL code instead of the expected search parameter.
To answer your question as asked, here is one solution:
string q = string.Format("SELECT collapsed_building.b_name,
collapsed_building.b_desc FROM collapsed_building
WHERE collapsed_building.b_name LIKE '%{0}%'", crimewithdate.text2);
(The line breaks are for readability only)
Do realize that an evil user could enter something like;
x'; TRUNCATE TABLE collapsed_building; SELECT * FROM collapsed_building WHERE b_name LIKE 'x
and wreck your whole day.
It is much better to pass crimewithdate.text2 as a parameter and not expose your database to bad people.
