How do you load and unload data using the commands load and unload in SQL Server? I am using UNIX Script to call isql.exe
Ex:
This code gives an error of "Incorrect syntax near keyword 'to'
unload to '/tmp/lot/test.unl'
select * from test
go
I want to be able to load and unload, byte-for-byte, a file to and from a field of data type IMAGE in a SQL Server CE database. The files are larger than 8000 bytes so IMAGE appears to be the way to go data type wise.
I'm using VB 2008 but pseudocode for any VS language would be awesome.
I was able to do this without much effort using ADODB and its stream object, fetching a recordset object and updating the appropriate data field one "chunk" of bytes at a time. I cannot for the life of me find a way of doing this using, for example, a SqlCeResultSet.
I've tried using ADODB to connect to a SqlCe SDF database file, using a connection string that I found online, and am able to write action and select queries successfully against the database... but when I try and return a recordset that is updatable, it returns an error. So no help there.
I've searched other threads in the forums, and online in general, and I've found information on loading/unloading graphic files using a memoryStream and the toArray method thereof, but this will not work as many of the files I want to load and unload as BLOBs are not graphical in nature. FileStreams do not implement the toArray method, so I can't just stream an arbitrary file's worth of bytes that way. I also do not want to change the original file in any fashion--e.g., a hash of the source file should be identical to the file after it has been loaded into the data field and then unloaded into a new file.
Any thoughts? Your help is MUCH appreciated!
I'm building a simple webform, except Visual Studio and my service provider have combined to drive me nutty.
First, I MUST use an ODBC connection to my remote SQL Server do to some unknown configuartion problem. I've been playing with Visual Studio for only a month, so normally when something goes wrong I can go look in the mirror and find the culprit. This is different. I've got a totally functional web form with a SQL Connection, but when I try to change it to an ODBC Connection, I get the following error.
An OdbcParameter with ParameterName '@CertHolder' is not contained by this OdbcParameterCollection
My coding is fine because I stole it straight from the walkthrough and it works. But the specifications that Visual Studio provide are quite suspect. Please note the failure to include some key "@" signs.

Hi,
I was wondering what SQL code would allow me to extract my results into a .txt.
For example:
Select * from employees
(What should I write here to enable me to import it into a .txt file and save it on a network drive?)
Thanks
Is there any faster and efficient way for exporting or unloading the data from a table (Contains about 400 to 500 million rows) into a flat or raw file. I am using SQL server 2005 and the Export Utility in SQL Server is very slow.
Any help is greatly appreciated...
I have used google and searched these forums but haven't found an answer.
Here is my problem:
I have MS SQL 2005 DB I need to backup to tape daily. I want the tape to eject (or unload) when it is complete. I know how to do it with a manual backup (simply check off the option), but there aren't any options I can see with a Maintenance Plan backup. I would rather not do a manual backup EVERY DAY.
I really don't understand why MS makes this so complicated...why would the option be in another area when you use a maintenance plan???
Thanks for replys!!!
Please, help

After deleting all the test data from all tables in a SQL 2000 database, is there a way to reset all the auto-incrementing fields back to zero in one shot? In Access, you can run the Compact and Repair option. Also, in Sybase SQL, there was an "unload/reload" option to reduce the database size. Is there a similar function in SQL2000? Thanks for all the help

I just have done the SSIS example in the tutorial document included when install SQL 2005 ENT. I have a problem that whenever I test to run, the service load all data from source with out noticing about the data (I mean it load all the data to the destination), I do it several time and it continue to load all without checking. That mean the data is dublicated when the schedule run???
I think there should be a paramete or something like that to help the engine just load the new data to the destination. Could you help please?

View 2 Replies View RelatedI am experiencing a situation where I issue a lengthy SQL command to MS SQL Server 7.0 through MTS and it "disappears" - no errors or recordsets are returned. The command is "SELECT * FROM CUSTOMERS WHERE LASTNAME LIKE 'SMITH%'". When I issue this command from SQL Query Analyzer it takes 27 seconds to return 87 rows. When I issue this exact same command through MTS it does not return at all.
I've used the SQL Profiler to analyze the requests. It shows the commands from MTS starting but they never stop (or at least the profiler never reports them as stopping). The same commands coming from Query Analyzer are reported as starting and stopping without fail.
Here's a twist: I can issue less demanding commands (ie, one that doesn't take so long to process) through MTS and they come back fine. For example, when a user logs into my application, I use an SQL statement to verify the user name and password and status the user as logged in. This is routed through MTS and it comes back fine in less than a second. Same application, same PC, same MTS and SQL server, same SQL database. The only difference is that the CUSTOMERS table has over 800,000 records and the USERS table has only 5 records.
PLEASE HELP!
Hi,
I am very new to sql server and I have been reading up on the dbcc commands. For instance, DBCC SHOWCONTIG where do I execute this command? I went into the cmd prompt and opened osql and typed:
1> DBCC SHOWCONTIG
2> GO
This gives me the information for what I assume is the master database. But, how do I use this command under the other databases?
Also, I have been trying to learn how to determine when to do index maintenance by using the index tuning wizard. But, I don't know what a workload is. Can someone point me in the right direction or give me some information about this topic.
Thanks,

Hi
Please can someone point me in the direction, i built a very badly designed database consisting of only one huge table when i first started databases, since learning about normalization i have designed and set up a new database which consists of many more tables instead of just the one. My question is where do i start in transfering the data from the old single tabled database to my new multi-tabled database?
I have MS SQL server 2005 managment studio if that helps, but want to transfer around 200,000 rows of data into the new database. Both new and old databases are on the same server.
thanks in advance
I have a job that runs between the hours of 10 PM and 9 AM. It launches a controller stored procedure that will call other stored procedure until the entire process is done.I would like the controlling stored procedure to only call the steps between the hours of 10PM and 9AM also.. So at 8:59 AM it will start the next step, but at 9:00 AM it will exit.

View 2 Replies View RelatedPlease forgive me if my questions seem very simple. I'm trying to pick up vb.net, asp.net, and SQL all at the same time, and while making progress in some areas I'm finding other questions I have harder to figure out where to look for answers.
First question - if I want to join 2 tables do the fields I'm joining on have to have the same name? I know they have to be of the same type, but does the name itself matter? For instance in this line of code I try to join forums
objdataadapter.SelectCommand.CommandText = "select * from msg_forums" & "JOIN users ON msg_forums.forum_moderators = users.user_ID"
Second question nagging at me, since I specify the table <msg_forums and users> before the field names <forum_moderators and user_ID> does it matter which one comes first? See, my primary table in this line is msg_forums, so do I have to specify it's field first, or does that even matter (or do I have it backwards and need to specify the other one first)?
Last question, and of course the root of what's caused me to wonder about all of this. I'm getting an error similar to some of what I found in the forums, but it's slightly different in that it says there is a problem near "OR". As far as I can tell I've written this correctly, and so, I'm stumped. Here is the error followed by the code. Thanks a bunch for any assistance anyone offers. :-) Incorrect syntax near the keyword 'ON'.

View 3 Replies View RelatedI was pointed to this forum by one of the admins who has started doing some consulting work for us. We did a major conversion over the weekend for our main production server to SQL 2005 from SQL 2000. We have used replication to go from the live OLTP server to a few dedicated report servers for all of our reporting needs. In 2000 this was pretty well established (though a pain when we had to migrate in changes; I love the 2005 schema features for replication).
The only problem we have really encountered today, the Day After, involves replication. A few minor things involve lack of knowledge (like nonclustered indexes don't replicate by default, that was an OOPS). But one thing I haven't figured out yet.
Replication is working -- we are updating three servers, and all three servers are getting updates. I have run a validation on one of them and it passed in full. However, the "undistributed commands" count never goes down. It actually keeps going up and up. I verified that by first running this on the subscriber:
select transaction_timestamp
from MSreplication_subscriptions
And taking the results of one of the three rows that came back and executing this with it:
sp_browsereplcmds @xact_seqno_start = '0x00000231000006ED000100000001'
which brought back all of the "undistributed commands". Within that list, I looked for sp_MSins_ procedures. I found a few and looked up on the subscriber the value to be inserted -- and it existed on the subscriber. So it still is in MSrepl_commands even though it has been sent out.
I am afraid that eventually the system will "think" that the process isn't working and deactivate the subscriptions. Also this is useless as a monitor. Since this is our first major replication in 2005, I am willing to bet that we are missing something. Does anyone have any advice?
