Don't double post. It's rude and against forum rules.
You've just asked this question. Why have you asked it again?

Hi
can u please help me to run following code.
___________________________________
declare @tablename varchar(20);
SET @tablename = 'table1';
select * from @tablename;
error: must declare @tablename
Thanks
Jayesh

Why do you want to do that in the first place?
If your table name is known only at runtime, you've to use dynamic sql
<br />
declare @tablename varchar(20), @sql nvarchar(256);<br />
SET @tablename = 'table1';<br />
set @sql = 'select * from ' + @tablename<br />
exec sp_executesql @sql<br />
SG
Cause is effect concealed. Effect is cause revealed.

Hi guys,
how do I insert into an oracle database table with a select statement from within mssql server2005 or 2000?
e.g
Oracle db: Table A id,msisdn,message
Msql server:Table A id, msisdn, message.
1 +476334566 Happy birhday
So I want to select this result from sql server database and insert into oracle Table A.
Thanks for you solutions.

Nasty
You need to set up a linked server from SQL to Oracle, this will give you access to the table.
This is a particularly nasty thing to have to do, the server name will then be hard coded into your procedure and will require modification when you promote the proc from dev/uat to production. (and I hate linked servers and I hate setting up Oracle and....)
Good Luck.
Never underestimate the power of human stupidity

INSERT INTO @Dates (date1, date2) <br />
VALUES (DATEADD(hh, -1, GETDATE()), DATEADD(hh, -2, GETDATE()))<br />
<br />
SELECT * FROM @Dates<br />

I have data of a start date, which I imported into SQL from an excell spreadsheet in which the date was an nvarchar type. So I imported it as smalldatetime, with the hopes that when I used a calender on my webpage it would use the same format and work beautifully! but it doesn't! for some reason, the calender uses the format: yyyy/mm/dd and the format I have it in my database is yyyy/dd/mm (and that's how it came with the import with the smalldatetime type). And I have fiddled with it all day and can't figure out how to get them to the same format as I can't get my SQL database to change my data to that format.
Am I doing something wrong or is this a silly problem that someone can help me with?
Thanks!

DATETIME and SMALLDATETIME fields will always have the same format. You need to convert it to a string and specify the output format you would like to use. The method for doing this will depend on the language you are using but any language should have a method for formatting date/time strings.
If you are using .NET for your web pages the DateTime class has overloaded ToString() methods for formatting the string. If you want the output of your SQL query to be formatted then use the CONVERT function:
.NET (c#)
<br />
myDateObject.ToString("yyyy/dd/MM");<br />
T-SQL
<br />
SELECT REPLACE(SUBSTRING(CONVERT(VARCHAR, GETDATE(), 120), 1, 10), '-', '/') AS Date<br />
T-SQL is less flexible, so you either need to concatenate calls to DATEPART (or YEAR, MONTH, DAY) or do something like the example above (SUBSTRING and REPLACE along with the 'style' argument of the CONVERT function).

Thanks, I will try that tomorrow morning. Will try the T-SQL script as I will only be using sql to do my coding.
appreciate the help

Substitute your date column for getdate() in this:
select replace(convert(varchar,getdate(),102),'.','/')
It gives you 2008/04/10

ok that's great for getting it into the correct format for todays date, but how do I get the last 20 000 rows of data to reflect the correct date format?!
|
|
|
|
|
I thought I was fairly clear, I said, replace the getdate() in this with your date column
so
select replace(convert(varchar,getdate(),102),'.','/')
becomes
select replace(convert(varchar,YOUR_DATE_COLUMN,102),'.','/')<br />
from YOUR_TABLE
Replacing YOUR_DATE_COLUMN and YOUR_TABLE with the names of your date column and your table name

kindly tel me how to handle Data Purging of previous month... We want to have the data of current month only...
|
|
|
|

I assume you have some kind of added date on your table(s), otherwise how will youi know the age of the data, but anyway:
delete tablea<br />
where addeddate < dateadd(month,-1,getdate())
This will delete anything over 1 month old today. Its easy enough to work on a month end/month start basis, I'll leave that for you to work out.
Also, if you have referential integrity between table you need to do the deletes in the correct order.
