I'd recommend explaining sprocs and functions, moving to Xml in the third lesson. Creating a connection to the database from a non-sql language has little to do with SQL.

What's their role? If design comes into play, you could reserve a week for the topic of database-normalization. There's examples on structures that break normalization on the wikipedia[^]; the update-anomaly is always a nice intro as people recognize it from the real world Smile | :)

After reading several documents , i am still confused whether to use Filestream or Varbinary for storing files?
my application need PDf files to be saved in database , size can be between 100 KB to 4 MB

I guess in order to use filestream we have to configure server to use that. while varbinary can work as it is.

what will be best way?Experts please comment.
Thanks.

We use filestream only to reduce the size of the database backup which is retained for some ridiculous number of years! documents are backed up seperately.

It could be the format of the date. Why is there a DATE-function on colmn1? Is it a varchar?

Please don't crosspost. The question should not be in the .NET forum.

Nas and FTP, sure, you can write applications to synchronize them with a database. What's an Airbox?

Export data in SQL 2008

Hi,

I just used the Import Export functionality in sql 2008 to export a table having about one million rows. I have exported to a flat file, and delimited with pipes.

For some reason, about 23,000 rows below, the one of the fields expands and as a result pulls down to the next row, creating a blank row, the data hence after is fine. Now and then we are getting these blank rows.

I have confirmed this data is of length 40 characters long or less.

What could be causing the odd line breaks in the flat file?

any ideas appreciated!!

Thanks!

Is there a carriage-return or line break embedded in the field?

If you can isolate one of the affected rows, try dumping the characters from the affected field:

SQL

DECLARE @FieldValue varchar(100);
SELECT @FieldValue = AffectedField FROM AffectedTable WHERE Key = @AffectedKey;

WITH E1(N) AS
(
    SELECT 1 
    UNION ALL SELECT 1 
    UNION ALL SELECT 1 
    UNION ALL SELECT 1
    UNION ALL SELECT 1 
    UNION ALL SELECT 1
    UNION ALL SELECT 1 
    UNION ALL SELECT 1 
    UNION ALL SELECT 1
    UNION ALL SELECT 1
),
cteNumbers (N) As
(
    SELECT
        ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) 
    FROM 
        E1 a, E1 b -- Cross-join = 100 rows
)
SELECT TOP(LEN(@FieldValue))
    N,
    Ascii(Substring(@FieldValue, N, 1)) As AsciiCode,
    Substring(@FieldValue, N, 1) As Character
FROM
    cteNumbers
ORDER BY
    N
;

You're looking for either a 10 or a 13 in the AsciiCode column.

bcp command in sql 2008

Hi,

What is wrong with this syntax?

I have used this so many times in sql 2005. Kind of new to sql 2008.
===
bcp "Select * From Webs.About" queryout mytest.dat -T -c
===

the error message is
Msg 102, Level 15, State 1, Line 1
Incorrect syntax near 'queryout'.

Not sure if this is it, but try enclosing mytest.dat in quotation marks. Otherwise, it looks like it should work to me.

Also, make sure you are running the bcp utility from the command prompt. I think if you try running it from a new query window within SMS that is exactly the error you will get. I'm pretty sure the quotation marks I mentioned in my previous post won't help unless the file name has a space in it.

How can I ran this through a new query window in SQL?

Using xp_cmdshell?

Thanks!!

Re: bcp command in sql 2008

NickPace11-Jul-13 9:23

Sure, you can use xp_cmdshell to run a bcp command from a query window. You might have to first turn on the ability for SSMS to use a Windows command shell as it is usually off by default. If needed, run the following commands first:

EXEC sp_configure 'show advanced options', 1
RECONFIGURE
EXEC sp_configure 'xp_cmdshell', 1
RECONFIGURE

Then run your xp_cmdshell using: EXEC xp_cmdshell '(your bcp command here)'

If needed, turn back off the ability to use Windows command shell with:

EXEC sp_configure 'xp_cmdshell', 0
RECONFIGURE
EXEC sp_configure 'show advanced options', 0
RECONFIGURE

Hi all,

I have posted the same question some time ago... but I didn't get any solution. Please read below first...

I want to connect a MySql Database.

Suppose.....

Database Name is mydb
Database located on PC-1 (IP- 192.168.0.10)
PC-1 user id = abc
PC-1 password= 123
MySQL Server user ID = root
MySQL Server password= mypassword

now what will be the connection string for PC-1 to connect to the database ?

now I want to connect the database(mydb) from another pc (suppose this pc name is PC-2 and the IP is 192.168.0.11)

what will be the connection string for PC-2 to connect the PC-1 database ?

I searched connectionstrings.com[^] and found ...
Standard

SQL

Server=myServerAddress;Database=myDataBase;Uid=myUsername;Pwd=myPassword;

and
Specifying TCP port

SQL

Server=myServerAddress;Port=1234;Database=myDataBase;Uid=myUsername;
Pwd=myPassword;

but nowhere found if the server pc (PC-1) is protected by user id and password. In this case what should I do ?

I Tried both the above connection string. They are Ok for PC-1 to connect its own database (localhost) but when I tried to connect the database from PC-2, I got the error

Quote:
Host '192.168.0.11' is not allowed to
connect to this server

I did. Twice. The answer "I cannot do that" doesn't mean that the answer you have been given was incorrect. You could have asked how to find the path. I'd answer that you can search your entire HD. By hand.

Most (professional) databases do not allow making remote connections in a default install. It's a security-thing. You cannot change that using a connection-string.

The fact that you're using XAMP simply means that the config-files are in another location than the default MySQL path. You'd have to find the file yourself, make the change to allow remote connections, and restart the server.

Open a command window on the CLIENT machine - NOT the database machine.

Verify that you have telnet.
Run telnet use the following command.

telnet 192.168.0.11 1234

There are two results to the above. First it succeeds which means it presents a blank screen (command window) or it returns an error message either quickly or after a couple of minutes.

Note carefully unless the above succeeds NOTHING you do with a connection string will EVER succeed at working.

If the above fails then you must look to something besides your application for a solution. Some POSSIBLE but not a complete list are the following
- The database is not set up to accept remote connections.
- The database is using a different port.
- The host name\ip address is wrong.
- there is a firewall that is preventing the connection.
- There is no possible network path from the client machine to the database machine.
