Not sure whether this is the right place for such a question, but i have a work colleague in need .......

Is it possible to output the results of a table from a DB into a filename that is dynamically generated using variables obtained from another query?

For example, I have a table called Orders
I want to extract the data for a specific day, and output to a filename called Orders_20100318
The date part of the file name will be extracted from a table using a query

Anyone??

Hi there

Thanks for the response.

So in the simple example below, I have 2 tables, one with the data to be extracted, and the other with the date to append to the filename:

USE [master]
GO
DROP DATABASE HelpAl
GO
CREATE DATABASE HelpAl
GO
USE HelpAl
GO
CREATE TABLE SimpleDate (AlsDate DATETIME)
CREATE TABLE SomeData (AlsData VARCHAR(10))

INSERT INTO SimpleDate (AlsDate)
SELECT CURRENT_TIMESTAMP

INSERT INTO SomeData (AlsData)
SELECT 'HELLO'
GO

This is the sqlcmd (I saved to a bat file to execute):

sqlcmd -S WS23\SQLSERVER2008 -E -d HelpAl -Q "SELECT * FROM SomeData;" -o D:\Results.bat -h -1

How do I use dynamic sql to create the filename Results_20100318.bat?

Thanks

Thanks Visakh16

I've now got the following:

DECLARE @str NVARCHAR(1000), @Date CHAR(8)

SELECT @Date = CONVERT(VARCHAR,AlsDate,112) FROM SimpleDate 

SET @str='sqlcmd -S WS23\SQLSERVER2008 -E -d HelpAl -Q "SELECT * FROM SomeData;" -o D:\Results_'+@Date+'.bat -h -1'

SELECT @str
EXEC (@str)

When I try to execute in Management Studio (with sqlcmd mode enabled, I get the error:

Msg 102, Level 15, State 1, Line 1
Incorrect syntax near 'S'.

I was getting this previously, hence used a bat file to execute the sqlcmd. Is there somethign I am missing, as I thought you could use the utility in MS if the mode was enabled?

You have to call sqlcmd.exe from xp_cmdshell inside T-SQL.
