The answer is to always use ISO 8601[^] date format when dealing with databases.

So your query becomes:

SELECT joinDate
FROM myTable
WHERE (joinDate>= '2009-01-01') AND (joinDate<= '2010-01-01')

If joinDate is a DateTime type, then this should work:

joinDate >= CONVERT(DATETIME, '01.01.2009', 104)

This is fully documented in the SQL Server documentation, which is all available on line.

Parse the strings to DateTime and use a parameterized query.

Hi,

I am using SQl 2005 for setting up a job which has 2 steps:-

Step 1: Executes a SP which sends out result to a file
Type : T-SQL
Command :
DECLARE @cmd varchar(2000),
SET @cmd = 'osql -E -S CONDOR -s";" -w2000 -d Arion -Q"EXEC dbo.ENRSP_Applicants" -o D:\Applicants.txt'
EXEC master..xp_cmdshell @cmd

Step 2: Mailing the txt file to the user
Type : Operating System(CmdExec)
Command :
"D:\MSSQL\JOBS\EmailFile.cmd" D:\Applicants.txt aa@yahoo.com ss@yahoo.com "Applicants Report"

This works fine but the user want some modification to the current Job
* the email subject to include the date also
* Wants the result set to be dumped into a CSV file and to attach the file to the mail
* Can you also tell me how to include a message to the mail plz?

I know its easy to get this all done using a SSIS but Can these be done using an SQL Job , if so can you plz help me with it?

Thanks in advance.

Warm regards,
Payal

SELECT INTO or CREATE TABLE

I have a SQL 2005 database and a SQL 2008 database. I want a simple SQL statement that will create/copy a table and its contents from 2005 into 2008 that I can use in a C# program. I know I can export using Mgmt Studio but I want to do in a a program. I am able to perform a SELECT INTO [MyDatabase2].[dbo].[mytable] SELECT * FROM [Mydatabase1].[dbo].[mytable] when they exist in different databases in the same machine and only in the same Database Instance but how do I across multiple instances or multiple machines.

Can anyone help ?

Thanks

Use this to connect to other server

EXEC sp_addlinkedsrvlogin 'server', 'false', 'userLocal', 'userRemote', 'remotePassword'

Code should look like this:

SELECT INTO [server].[MyDatabase2].[dbo].[mytable] FROM [Mydatabase1].[dbo].[mytable]

Blikkies,

Thanks for the info. Just a couple follow up questions.

So on the 2005 SQLExpress Server I have an instance of SQLEXPRESS and on 2008 SQL I have an DB instance of MY2008DB I would do the following if I am running on the 2008 system.

EXEC sp_addlinkedsrvlogin '\\MY2005Server\SQLEXPRESS', 'false', 'sa', 'sa', 'sa'

SELECT INTO [MyDatabase2].[dbo].[mytable] FROM [\\MY2005Server\SQLEXPRESS].[Mydatabase1].[dbo].[mytable]

and if I was running this on the 2005 server it would be the opposite ?

EXEC sp_addlinkedsrvlogin '\\MY2008Server\MY2008DB', 'false', 'sa', 'sa', 'sa'

SELECT INTO [\\MY2008Server\MY2008DB].[MyDatabase2].[dbo].[mytable] FROM [Mydatabase1].[dbo].[mytable]

Or how does that work with the DB Instance name ?

thanks

Hi everyone,
I have a table with 4 columns = "Name", "Age", "Place","Salary".
I want to display only "Name" and "Age" column with entries in Datagridview in my Form.

Cany anyone please tell me how to do this?

Re: Display few columns in datagridview.

24-Sep-09 12:49

I'll assume you're using VB.NET or something similar...

If you don't want to show certain columns, simply don't show them. This may entail turning off auto-generate columns in your grid and adding in your own custom column definitions (lots of examples of grids can be found on Google.)

The other alternative is to make your datasource come from a query or view rather than grabbing the whole table.

Is there a way to do that? I'm using sql server 2005 express edition.

Why dont you use Windows Service to create backups. Generally Backup doesnt take network paths. so it is better to do this in your own server in a specific folder and a service will move the file from the place to where you want.

You can even do what abishek said, with a simple batch file, and a scheduled task.

How to Optimize MySql Database?

Hi Experts,
We have created an application in ASP.Net 2.0 and with MySQL 5.0.67 as Backend. The application was running great from months, but recently we have discovered that there is a performance degrades in the database. Actually database was designed by one of my colleague how didn’t have much of database background so database design is not a professional one. I would also like to mention that this is my first Project on MySQL. I have worked on SQL Server till now. When I started analyzing the database I found indexing was missing in the tables. Introduction of Indexes has improved the performance somewhat. Can any one please tell me what else can I do to improve the performance.

Please help me its urgent

Thanks and Regards,
Paramhans Dubey

Do what you should have done in the first place, employ someone who knows what they are doing. Without the schema, useage, etc its impossible to say what should be done anyway.

Hi
Thanks for your reply and suggestion. We are in process to recruitin someone who knows the job, but meanwhile we just cant sit and wait for him to join and do the job. Anyways I was going through one article where I came to know about Table Engines and their usage. I also came to know there Using MyISAM table engine can improve the read perfomance of the tables but the author also wrote that Your tables will get corrupted eventually but there was no explaination about how and why it happens?
I fyou know the reason then kindly tell me

Thanks and Regards,

Nesting a stored proc call in a where clause?

24-Sep-09 12:45

OK, so your DB started performing poorly after it ran for awhile....that's a pretty broad problem, but here's a few things you might try:

1) I fully agree with Bob's post - if you want it to work correctly, get someone who knows what they're doing to set things up properly. (Though I understand that doesn't fix your problem today.)

2) Check for any tables that have grown excessively large. It's possible that you have some large logging / history tables and such that can easily be archived and deleted from the working tables.

3) If there's any way to narrow your problem down to a few areas (perhaps the top 2 or 3 stored procedures you're having trouble with?) you can look at modifying indexes specifically to help with those queries - just be sure you don't replace one problem with another.

4) You could always throw more hardware at it for a temporary fix...

If you have any more specifics about what the problem is, perhaps we could better help.

Re: Nesting a stored proc call in a where clause?

23-Sep-09 14:23

Here's the short question - how can I make this work?

create function callme()
returns TABLE AS
RETURN(exec MyExistingSP)

And the longer question on why I'd want it to...

* I've got several stored procs that return table result sets that are fairly large (or larger than I care to scroll through)
* Often, I'm doing ad-hoc queries where I only want to see one or two rows returned by the stored proc.
* If I need to whip up a function/stored proc to allow this, it would be handy if it would take the stored proc name as a parameter
* Would also be nice to take a subset of the column list in a select, or add an order by
* I'm most interested in SQL Server 2000+
* Performance is not an issue (within some reason...), as this is only for typed in ad-hoc queries

select column1, column2
from callme('MySP')
where id > 500
order by LastModified --> would be nice to see the subset...

I can do this easily with a multiline function for each stored proc, but it's not worth that much work. I keep hoping there's just a twist of syntax I'm missing, but I'm afraid that's not the case...

Any thoughts?

Thanks,

Dave

You can't do this -
1. You can't call a proc from a function
2. You can't pipe the output from a proc into a table

Regarding only getting the first few rows, try

SET ROWCOUNT 10
exec sproc
SET ROWCOUNT 0

This will just return the 1st 10 rows.

As for the rest of it, the only way to do it would be some pretty complex dynamic sql.
