Read DataBase File
Jan 17, 2002
Hi,
I received a SQL Server 6.5 database (.dat and .Log files). I'm currently running 7.0. Is there any way to read/import this data?
I tried to do this:
I have installed SQL Server 6.5. And After install, I have created a database with the same names (.dat an .log) and make it bigger than the first .dat and .log files.
Then, I have stoped the SQL server service, have deleted the .DAT and .LOG files that i have created, and have copied the first .DAT and .LOG in their place. I have Started the SQL server service and the database was beeing suspected. I stil unable to read data.
Can you help me?

hello!
i'm an sql server beginer. i was wondering if some of you guys can help
me out. i need for the sql server to be able to read an outside file (just text) and be able to run a script that will insert it in the database. it's a dcc output file. we've tried running this script:
DROP TABLE tests
go
DECLARE @SQLSTR varchar(255)
SELECT @SQLSTR = 'ISQL -E -Q"dbcc checkdb(master)"'
CREATE TABLE tests (Results varchar(255) NOT NULL)
INSERT INTO tests EXEC('master..xp_cmdshell ''ISQL -E -Q"dbcc checkdb(master)"''')
and it's running good but the problem is the results of the dbcc here did not come from a file but directly after executing the dcc command. is there a way to do it?
thank's for the help!

I have two database files, one .mdf and one .ndf. The creator of these files has marked them readonly. I want to "attach" these files to a new database, but cannot do so because they are read-only. I get this message:
Server: Msg 3415, Level 16, State 2, Line 1
Database 'TestSprintLD2' is read-only or has read-only files and must be made writable before it can be upgraded.
What command(s) are needed to make these files read_write?
thanks

i have a database which get refreshed every day from client's data . and we need to pull heavy data from them every day as reports . so only selects happens on that database.
we do daily population of some table in some other databases from this daily refreshed DB.
will read uncommitted or NOLOCK with select queries to retrieve data faster.
there will be no dirty read as there are NO DML operation in that database so for SELECT which happens concurrently on these tables , will NOLOCK work?

Any easy way for a batch file or automated process to read from one db and table and what ever entry is missing out of another database + table it writes those missing entries to.
This is a simple table in one db that is filled with usernames, I want to see if there are missing usernames in another db and table and write those entries.
db1.usr_table.usr_name = jdoenew
If jdoenew is missing in the 2nd db I will need to write entries like:
db1.usr_table.usr_name = jdoenew
db1.usr_table.password = tmppassword
db1.usr_table.active = 1

Greetings, I have just arrived back into the country (NZ) and back into ASP.NET.
I am having trouble with the following:An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
It has only begun since i decided i wanted to use IIS, I realise VWD comes with its own localhost, but since it is only temporary, i wanted a permanent shortcut on my desktop to link to my intranet page.
Anyone have any ideas why i am getting the above error? have searched many places on the internet and not getting any closer.
Cheers ~ J

Hello Experts,
I am createing one task (user control) in SSIS. I have property grid in my GUI and 2 buttons (OK & Cancle).
PropertyGrid has Properties like SourceConnection, OutputConnection etc....right now I am able to populate Connections in list box next to Source and Output Property.
Now my question to you guys is depending on Source Connection it should read that text file associated with connection manager. After validation it should pick header (first line of text file bases on record type) and write it into new file when task is executed. I have following code for your reference. Please let me know I am going in right direction or not..
What should go here ?
->Under Class A
public override DTSExecResult Execute(Connections connections, VariableDispenser variableDispenser, IDTSComponentEvents componentEvents, IDTSLogging log, object transaction)
{
//Some code to read file and write it into new file
return DTSExecResult.Success;
}
public const string Property_Task = "CustomErrorControl";
public const string Property_SourceConnection = "SourceConnection";
public void LoadFromXML(XmlElement node, IDTSInfoEvents infoEvents)
{
if (node.Name != Property_Task)
{
throw new Exception(String.Format("Invalid task element '{0}' in LoadFromXML.", node.Name));
}
else
{
try
{
_sourceConnectionId = node.Attributes.GetNamedItem(Property_SourceConnection).Value;
}
catch (Exception ex)
{
infoEvents.FireError(0, "LoadFromXML", ex.Message, "", 0);
}
}
}
public void SaveToXML(XmlDocument doc, IDTSInfoEvents infoEvents)
{
try
{
// // Create Task Element
XmlElement taskElement = doc.CreateElement("", Property_Task, "");
doc.AppendChild(taskElement);
// // Save source FileConnection
XmlAttribute sourcefileAttribute = doc.CreateAttribute(Property_SourceConnection);
sourcefileAttribute.Value = _sourceConnectionId;
taskElement.Attributes.Append(sourcefileAttribute);
}
catch (Exception ex)
{
infoEvents.FireError(0, "SaveXML", ex.Message, "", 0);
}
}
In UI Class there is OK Click event.
private void btnOK_Click(object sender, EventArgs e)
{
try
{
_taskHost.Properties[CustomErrorControl.Property_SourceConnection].SetValue(_taskHost, propertyGrid1.Text);
btnOK.DialogResult = DialogResult.OK;
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
#endregion

I have a filetable that contains a binary file. I need to do a selective read of the file stored in the file table. I can write a C# CLR function that will open the file, read n bytes the from a starting byte. Or I can write a SQL statement that reads the stream in the filetable into a VARBINARY variable using SUBSTRING beginning at the starting byte (offset from 1) for the same n bytes.
Both give me the same result. However, the SQL statement takes considerably longer to read. I know there is overhead in reading through SQL (interpreted language), but the difference in performance is substantial, and I can only attribute this performance degradation if SQL first tries to "load" the entire stream before it identifies the portion of the stream that it needs to read beginning at the starting byte offset.
I wonder if this is the case or if there is another option to read a stream from a filetable directly through SQL queries that is more efficient.

Anyone reading XML disk-files into SQL Server?
I have a process that I may want to do this with.
It would be a stored procedure that would read the XML attributes into 2 tables, the number of attributes could be 1-N, so I thought XML would be a good choice. Also, one of the attributes could be up to 4000 characters. I think this may limit our options, can 100-150 4000 character strings be passed in a standard call to a query/proc in SQL?
Currently the client application makes round-trip network calls to save upwards of 100 pairs of data. 1 header row, and many detail rows. All within a transaction.
I think If we move an XML file to the SQL box, then do all the import/save work on the "Server" side it would be much better. Cutting the transaction time down a lot by not doing so many round-trips at network speed...
Thoughts?

Hi All
I am trying to load DBF files into SQL server within CLR (actually if just running the select statement outside, say within the SQLQuery window, i got the same result), but with the following error:
Msg 7314, Level 16, State 1, Line 1
The OLE DB provider "VFPOLEDB" for linked server "MYDBF" does not contain the table "T8866064". The table either does not exist or the current user does not have permissions on that table.
I created the linked server in this way
EXEC sp_addlinkedserver
@server = 'MYDBF',
@provider = 'VFPOLEDB',
@srvproduct = 'My Data',
@datasrc = 'c:data'
i did not create the login since my SQL instance is running under a superaccount with all privilege.
What frustrates me is that i can read most of the dbf files, but just a few of them is not readable.
Can anyone give me some hints on it?
by the way, i am using vfp9.0
thanks
michael

How can I read one external file (*.txt,*.csv) through
stored procedure in MS Sql Server 2000 ?
On the database Interbase its very simple :
[CREATE TABLE table [EXTERNAL [FILE] ’ <filespec>’]
( <col_def> [, <col_def> | <tconstraint> …]);
EXTERNAL [FILE]“<filespec>
” Declares that data for the table under creation resides
in a table or file outside the database;
<filespec> is the complete file specification of the
external file or table]
Please advice
Thanks
