Hi All,
I'm no SQL wizard. :(
I've been asked for a query that will:
1. For all non-system databases on the server.
2. For all tables in the dabase.
3. Export in text form every field in every record to a disk file named from the table name.
Requirement 1 may not be required, they will be ok entering the name of the database if necessary.
They would like to use BCP but I'd be quite happy to tell them that that just wont work and they must run a query.
If possible, it should work on SQL 2000 and SQL 2005.
Anyone got something like that? Thanks!
Paul

If you don't want to create a stored procedure then just run it as a script.
IMHO this is one SP I'd happily have in my database! Very handy.
Here it as a script. You can just paste it into QA and run it. No points for me please.
DECLARE @DatabaseName VARCHAR(255)
SET @DatabaseName = 'The database name'
DECLARE @TableName VARCHAR(255)
DECLARE @CopyString VARCHAR(255)
DECLARE @CopyStringCmd SYSNAME
DECLARE TableList CURSOR FOR
select Name from sysobjects where xtype = 'U'
OPEN TableList
FETCH NEXT FROM TableList INTO @TableName
WHILE @@FETCH_STATUS = 0
BEGIN
SET @CopyString = 'bcp "' + @DatabaseName + '.dbo.' + @TableName + '" out "C:\bcpout\'+ @DatabaseName + '_' +@TableName+'.txt" -c -q -U"sa" -P"sapwd"'
SET @CopyStringCmd = CAST(@CopyString AS SYSNAME)
exec master..xp_cmdshell @CopyStringCmd
FETCH NEXT FROM TableList INTO @TableName
END;
CLOSE TableList
DEALLOCATE TableList
Excellent so far. :)
Now is it possible to use something like this technique I've used in Access?
SELECT "BCP "+ [Name] + ... AS Cmd from sysobjects where xtype = 'U'
i.e. build a sequence of BCP commands directly from the table names.
I could then execute the BCP output that dumps each table as another batch file.
Any chance? Bos really does not want to use SQL scripts, he's a 'cmd' window person. :)

ah. I see. Pretty paranoid boss. Anyway, you can do the following.
Use xp_cmdshell to execute the dos command "echo" to write the stuff to a batch file as shown below. I have not tested this as I am currently on a linux box. You can even put the following transact sql in .sql file and execute it using osql from the command line instead of using query analyzer
DECLARE @DatabaseName VARCHAR(255)
SET @DatabaseName = 'The database name'
DECLARE @TableName VARCHAR(255)
DECLARE @CopyString VARCHAR(255)
DECLARE @CopyStringCmd SYSNAME
DECLARE TableList CURSOR FOR
select Name from sysobjects where xtype = 'U'
OPEN TableList
FETCH NEXT FROM TableList INTO @TableName
WHILE @@FETCH_STATUS = 0
BEGIN
SET @CopyString = ' echo bcp "' + @DatabaseName + '.dbo.' + @TableName + '" out "C:\bcpout\'+ @DatabaseName + '_' +@TableName+'.txt" -c -q -U"sa" -P"sapwd"' + ' > c:\test.bat'
SET @CopyStringCmd = CAST(@CopyString AS SYSNAME)
exec master..xp_cmdshell @CopyStringCmd
FETCH NEXT FROM TableList INTO @TableName
END;
CLOSE TableList
DEALLOCATE TableList
oops, that should be like this. The first one creates the c:\test.bat and the next one then appends each line to the file.

I have written a procedure for you which you can create in each of your databases. This procedure will enable all tables in a database to be exported using BCP by running a single command against the relevant database. For this procedure to work in your databases, just put the correct sa password in the procedure, as well as the output path, and run it in your database.
----------
CREATE PROCEDURE spBCPAllTables
@DatabaseName VARCHAR(255)
AS
DECLARE @TableName VARCHAR(255)
DECLARE @CopyString VARCHAR(255)
DECLARE @CopyStringCmd SYSNAME
DECLARE TableList CURSOR FOR
select Name from sysobjects where xtype = 'U'
OPEN TableList
FETCH NEXT FROM TableList INTO @TableName
WHILE @@FETCH_STATUS = 0
BEGIN
SET @CopyString = 'bcp "' + @DatabaseName + '.dbo.' + @TableName + '" out "C:\bcpout\'+ @DatabaseName + '_' +@TableName+'.txt" -c -q -U"sa" -P"sapwd"'
SET @CopyStringCmd = CAST(@CopyString AS SYSNAME)
exec master..xp_cmdshell @CopyStringCmd
FETCH NEXT FROM TableList INTO @TableName
END;
CLOSE TableList
DEALLOCATE TableList
GO
--------
To execute the procedure, just use the following command
exec dbname.dbo.spBCPAllTables 'dbname'
the procedure will then export all the tables in database dbname to text files in the format dbname_tablename.txt
you can play around with this script to tweak if for your needs
