Why does SQL Server Express 2005 save stored procedures in SQL files? That is so annoying.

I'm wondering what the best way to implement plug-in reports is. If I use Crystal, which I haven't for over a year, I have the benefit of built-in selection parameters, so I could possibly get away with just 'dropping' the report files into a store, and having my code pull the full report name from the file somehow. The report itself will then handle the selection parameters.
If I do a custom solution, I could follow a plug-in assembly architecture, where each report is packaged as its own class library, with a custom selection screen1 and output grid.

During your SELECT statement you can get the timestamp and keep it for updating purpose later.
I usually save the timestamp as long variable.
On your update statement, pass the timestamp as a parameter along with the rest that you need to make sure you update the correct version of the data, e.g.
UPDATE customer<br />
SET [name] = @newname<br />
WHERE [id] = @id<br />
AND [rowversion] = @timestamp <-- timestamp value

Dear all,
I have the following case:
In a SQL db, each time a row is changed in a specific table ( say OriginalTable ) i need to insert a row for each changed column in a specific table say ( HistoryTable ) by the following values:
1- The OriginalTable Column name ( i.e. the column that its value is changed )
2- The Old value ( existing before the update process )
3- The New value ( existing after the update process )
I dont know if this can be done using SQL or programmatically from the code.
Plz, if anyone know the solution of that problem using any SQL or Code reply me as soon as possible. ( Note : my application is an ASP.Net project)
thank u all

You can use an SQL TRIGGER to create these records automatically whenever a modification is performed. (see CREATE TRIGGER in the SQL documentation).
Also, you can use the COLUMNS_UPDATED() function to determine which columns have been changed (in order to produce the text for the column name).
Hope this helps.
Regards,
Alex

You need to grant privileges to a user with an IP address.
Here's a link[^] with simple demonstration on how to set the user.
I don't think you can setup remote connection without the IP address, but I'm not an expert in MySQL though.

Thanks Edbert. I tried that but no luck. It might be another problem all together. It is a Windows box trying to connect to MySQL on a Linux box, so maybe there is a TCP/IP or port problem.

Sorry I can't help much.
Last time I setup mysql was on Windows Server 2003. The PHP-Linux guy who built a website didn't know how to work on Windows and decided to host it somewhere else Linux-friendly.
If you do searches on Google, looks like you're not the only one having trouble connecting to MySQL on a Linux box. Here's a link to mysql manual on connection problem[^] that might have what you need.
Good luck.

The connection string should point to the machine that the SQL Server is installed on. If it has a named instance that is needed also. For example
Server=MyServerMachine or
Server=MyServerMachine\NamedInstance

Most hash used for password is one-way hash, i.e. you cannot de-hash the value into text anymore, which is done for security reasons.
You can, however use a select statement to find if there's a user with username specified and the hashed value of the password given, i.e.
SELECT COUNT(*) FROM user<br />
WHERE username = 'user' AND pass = PASSWORD('pass')

Hello guys,
I want your help
I want to store different files (their data) into the data base how do I do that?
I have a table called Files with one blob field FileData, the table's structure is as follows
File(FileID IDENTITY(1,1), FileData text);
I am doing this application in MFC (VS 2005).
I accepted the file name from user, opened it using CFile::open method ,read data into TCHAR buff & inserted into DB as follows,
TCHAR szBuff[_MAX_PATH];
CString strSQL = _T("INSERT INTO Files(FileData) VALUES '%s'");
CString str = strSQL;
strSQL.Format(str,szBuff);
m_pDataBase->ExecuteSQL,strSQL);
tell me if I am doing mistake by taking a TCHAR array & what is the alternate way for it.
Remember that the files could be of any type & later stage I need to read the file data back.
I am new to MFC so please help me
Thanks in advance

I'm trying to generate the SQL scripts of a SQL Server database automatically by the use of the ScriptTransfer method of the Database2 COM class. It would have been nice if the DROP commands would be generated for the foreign keys too but it seems impossible. I've been playing with all the options of the Transfer object but all in vain: everything gets generated but the FK DROP statements.
I don't know if it is relevant or not but here are two fragments from the C++ code that i have used so far:
// ...
#define SQL_SCRIPTING (
SQLDMOScript_ClusteredIndexes |
SQLDMOScript_Indexes | \
SQLDMOScript_IncludeHeaders | \
SQLDMOScript_PrimaryObject | \
SQLDMOScript_Drops )
// ...
pTransfer->ScriptType=(SQLDMO_SCRIPT_TYPE)SQL_SCRIPTING;
pTransfer->CopyAllTables=VARIANT_TRUE;
pTransfer->CopyAllStoredProcedures=VARIANT_TRUE;
pTransfer->CopyAllFunctions=VARIANT_TRUE;
pTransfer->CopyAllTriggers=VARIANT_TRUE;
pTransfer->CopyAllViews=VARIANT_TRUE;
pTransfer->CopyAllObjects=VARIANT_TRUE;
pTransfer->CopySchema=VARIANT_TRUE;
pTransfer->DropDestObjectsFirst=VARIANT_TRUE;
Any workaround on this issue?

you can select data from tables in different databases as:
Select A.Flds , B.Flds From Server1.db1.dbo.Table1 A<br />
Inner Join Server1.db2.dbo.Table1 B A.Fld = B.Fld

what is the query for displaying records with a particular date eg. Feb 02 2006 and displaying records within a range eg. Feb 02 2006 to Feb 04 2006
in which format the user have to input the date in asp.net?

Thanks in advance

I always use ISO format when typing SQL in Query Analyzer, but for accessing the application through ADO.NET (ASP.NET is for web applications and has nothing to do with the database). I don't worry about the date format as I use parameters. For example
SqlCommand cmd = new SqlCommand();
cmd.Connection = myConnection;
cmd.CommandText = "SELECT * FROM MyTable "+
"WHERE SomeDate BETWEEN @startDate AND @endDate";
cmd.Parameters.Add("@startDate", theStartDateTimeObject);
cmd.Parameters.Add("@endDate", theEndDateTimeObject);
SqlDataReader reader = cmd.ExecuteDataReader();
theStartDateTimeObject and theEndDateTimeObject are DateTime objects. If you use these then you don't need to know what format to write the dates in to the SQL String - and nor should you need to convert it.
The database should be used for storing information. You shouldn't really be doing any localisation functions with the database as that is all presentation layer stuff.

Are you serious? Its the same framework - the only differences are a few minor syntactical ones.
Dim cmd As SqlCommand
cmd = New SqlCommand()
cmd.Connection = myConnection
cmd.CommandText = "SELECT * FROM MyTable " & _
"WHERE SomeDate BETWEEN @startDate AND @endDate"
cmd.Parameters.Add("@startDate", theStartDateTimeObject)
cmd.Parameters.Add("@endDate", theEndDateTimeObject)
Dim reader As SqlDataReader
reader = cmd.ExecuteDataReader()
