Is it posible to write a trigger for a SQL db that fires on a date change?
i need to log the communications between an app and a palm scaner, but this would become one huge table within months. the idea is to only keep the latest 30 days of records in that table. so the trigger has to fire every day, check the date on the entries and delete it if its over 30 days old.
Thanx

you shuld look into using a windows service that would run on the server that has that database. that Service should run at say 12am each night and delete the records as necessary
hope it helps

yeah we thaught of that, doing it programmaticly. but it would be sweet if a SQL trigger could handel that for us.
Thanx man

We are trying to create a series of XML scripts from a Mysql database query. We are having two issues that we are not smart enough to figure out & could use some help;
1) We need to save each row of the query result as a separate xml file i.e. running the query may generate 100 results - each row being a full XML string which needs to be saved as a separate file. Is there a method to accomplish that goal?
2) Embedded in the XML script are DOS file paths with back slash separation. When we save the query result, we end up with double back slashes because Mysql uses the back slash as the esc char. Is it possible to get a single back slash w/o needing to externally edit the file?
Thanks for any suggestions!

I think this will do it - it looks a bit horrendous and I'm sure there must be an easier way 
declare @start datetime, @end datetime, @month varchar(10)<br />
<br />
set @month = 'feb'<br />
<br />
select @start = convert(datetime, '01-Apr-' + convert(varchar,datepart(year,dateadd(year,-1,getdate()))))<br />
select @start<br />
<br />
select @end = convert(datetime,dateadd(day,-1,dateadd(year,1,convert(datetime, '01-' + @month + convert(varchar,datepart(year,dateadd(year,-1,getdate())))))))<br />
select @end

If we delete or update a row in a table; the no of changed row shows as n rows affect.
Here is the example.
Ex: update TableName set Column1='N' where Column2=2
Output: 4 rows affected
In this i need to get the value 4. How to fetch that value.
Can anyone help me out 
Regards,
LEE

In SQL Server you can get this value by using the global variable @@rowcount. The variable contains data about the number of rows affected by a sql statement and is updated each time you run a statement.

Hi i have a doubt,.
I have a view with two colums from table1, two columns from table2,
if i changed the data in view then updation occurs in both tables are not?
Another doubt..
If i combine two tables data in to one view...
how much space it takes.. suppose table1 takes 2kb, table2 takes 4kb
then view takes 6b or less ?

Nope. To do that, you need to have an 'instead of' trigger on your view.
Satish - Developer wrote: If i combine two tables data in to one view...

Theoretically, a view does not occupy storage space, except for the view definition stored in one of the system tables. When you query your view, it'll run the select query present in it's definition and return the result set.

What is the error? Did you check what the error message means before posting?
If you can't be bothered to do a little investigation yourself, I can't be bothered to help you

Hello
Does anyone know how to get child rows of a row as a string?
I mean, lets say that i have 3 tables:
Students, Courses, and Student_Courses to track the courses that each student is taking
Each student can take many courses at the same time
What i want to retrive is:
Column 1 Column2
Alex 'Course1, Course2, Course3, Course6'
Alexei 'Course3, Course6'
Alexa 'Course2, Course3, Course6'
I dont want to use cursors and i would prefer to do this in SQL server
Im only wondering if SQL has a intruction to acomplish this or if anyone knows an easy way to do this
Thanks for your time

Try this:
<br />
create table student (StudentID int, Name varchar(50))<br />
create table student_course (StudentID int, CourseID int)<br />
create table course (CourseID int, Name varchar(50))<br />
<br />
insert into student select 1,'Fred'<br />
insert into student select 2,'Joe'<br />
insert into student select 3,'Mary'<br />
<br />
insert into course select 1,'Maths'<br />
insert into course select 2,'Cooking'<br />
insert into course select 3,'Languages'<br />
<br />
insert into student_course select 1,1<br />
insert into student_course select 1,3<br />
insert into student_course select 2,1<br />
insert into student_course select 3,1<br />
insert into student_course select 3,2<br />
insert into student_course select 3,3<br />
<br />
go<br />
<br />
<br />
CREATE FUNCTION dbo.udf_GetStudentCourses(@StudentID int)<br />
RETURNS VARCHAR(1000) AS<br />
<br />
BEGIN<br />
DECLARE @CourseList varchar(1000)<br />
<br />
SELECT @CourseList = COALESCE(@CourseList + ', ', '') + c.Name<br />
FROM Student_Course s, Course c<br />
WHERE s.StudentID = @StudentID<br />
and c.CourseID = s.CourseID<br />
<br />
RETURN @CourseList<br />
END<br />
go<br />
<br />
<br />
select Name,dbo.udf_GetStudentCourses(StudentID)<br />

SITUATION:
An external process (web server) writes one row into a table (WipTable) in my SQL 2005 server, and it takes too much time for my 'INSERT' trigger to execute in once, since the data process and checking is big and time consuming.
This 'INSERT' trigger to this 'WipTable' need to end quickly, but, the trigger takes too much time to finish the transaction. The only step required at this stage is updating a 'confirmation status' field into the table.
My goal is simple:  avoiding the big delay before COMMITTING the first stage of the transaction, and instead split the task in 2 parts (like an Interrupt Service Routine would react):
1) first, do the simple things that place some data (to put a 'CONFIRMATION' status) and write one 'row task' into another table (RequestTable). Then, the RequestTable's TRIGGER would do the rest of the work in ANOTHER transaction.
2) The second table that would then be triggered would take more time to execute but
QUESTION:
How to 'force' the real and effective completion of the transaction, so that another (longer) transaction could begin just after it (being in fact 'triggered' by the first transaction because of an INSERT into a second table possessing an 'INSERT' trigger) ?
