Hi,
I have a USERS table
in which have the following fields
USER_ID,
COMP_ID,
PASSWORD
CREATED_BY
CREATED_DATE
DELETED_BY
DELETED_DATE
here created_by will contain that user id who is creating this user,
but i want your opinion on deleted_by and deleted_date
Is it feasible put this two field in this table or i put it in another table.

It all depends on whether you are really deleting or just flagging as a delete - obviously if its a real delete there will be nothing to update!

No, it is flagging as delete thru another field ACTIVE.

Put it in the same table where ACTIVE is present.

In which case use the original table.

The easiest way is to back up your local DB and restore it on the server.
You may be able to copy the .MDB and log files to the server and then use attach.

i want to store gujarati(language)data in database sql server2005 and i want to retrieve that data from database using asp.Net 2.0 (2005)
how can i do above thing???
please provide answer and suggestion ASAP it is very important....

It is not clear what it is you want to do. Are you wanting to store strings that are in a different language (encoded in Unicode perhaps) and then retrieve them for display? Or are you wanting to change the sorting rules for the database to follow the conventions of a different language?
What approaches have you tried, and what problems have you encoutered?

I see this is your first post on Code Project.
Take some time to read through the following, excellent article: Some guidelines for posting questions in the forums[^].
After that try to solve the problem with the tools you've got (help, google, msdn, etc). When you have a specific problem you cannot solve, post a question providing enough information about your (specific) problem and people try to help you.
About your question: Start with selecting the correct collation to your database. Refer to: Windows Collation Name (Transact-SQL)[^].
The need to optimize rises from a bad design.

Use Nvarchar type for your column. Nvarchar can keep Unicode characters.

Hello All,
I am sorry for bothering you guys with this but I did perform so "due diligence" to find the answer to this and I am just stuck. Any help thrown my way will be greatly appreciated.
I have an ODBC datasource on a PC that connects to a proprietary db. I use Access (link tables) and the datasource to retrieve and examine data.
My question is: I have SQL Server 2005 and I would like to know if there is a way that I could somehow use the ODBC connection to connect with SQL Server. I am certain that I could do a lot more with the data linked to SQL as opposed to using Access.
I hope I have made my intentions clear and again, thank you (whomever you are) for the assistance.
Best regards,
F

Certainly, SQL Server and all the major DBs support ODBC, try these guys clickety[^]
They will have ODBC examples on there somewhere.

Hi,
i'm having a very strange problem on my code, i'm on VS2008 with .net 3.5 and with SQLServer 2005, i have the 'correct' data tracked with the profiler tool;
SELECT x.columnName, x.columnOrdinal, x.columnTypeID, x.columnMaxLength, x.columnPrecision, x.columnScale, x.columnAllowNull, x.columnIsIdentity, x.columnFKTable, Case When y.Name Is Null Then 'No' Else 'Yes' End As columnPrimaryKey
FROM ( select sc.name columnName, sc.colid columnOrdinal, sc.xusertype columnTypeID, sc.length columnMaxLength, sc.xprec columnPrecision, sc.xscale columnScale, sc.isnullable columnAllowNull, (sc.status & 0x80)/0x80 columnIsIdentity, sor.name as columnFKTable, sc.colorder
FROM [teste].[SYS].[syscolumns] sc
INNER JOIN [teste].[SYS].[sysobjects] so ON sc.id=so.id
LEFT OUTER JOIN [teste].[SYS].[sysforeignkeys] sfk ON so.id=sfk.fkeyid AND sc.colid=sfk.fkey
LEFT OUTER JOIN [teste].[SYS].[sysobjects] sor ON sor.id=sfk.rkeyid
WHERE SO.Name='Centro' ) AS x
LEFT JOIN
( SELECT c.name, c.colid
FROM sysindexes i
INNER JOIN [teste].[SYS].[sysobjects] t ON i.id = t.id
INNER JOIN [teste].[SYS].[sysindexkeys] k ON i.indid = k.indid AND i.id = k.ID
INNER JOIN [teste].[SYS].[syscolumns] c ON c.id = t.id AND c.colid = k.colid
WHERE i.id = t.id AND i.indid BETWEEN 1 And 254 AND (i.status & 2048) = 2048 AND t.id = OBJECT_ID('Centro')) As y
ON x.columnName = y.Name
ORDER BY x.colorder
the result will have this row of data:
centroID 1 56 4 10 0 0 1 NULL Yes
the problem it's on the last column, here is a 'Yes' and on VS, while debugging right after the dataadapter.fill i get a 'No', obviously with the same query.
Here is the code i used to get the data from the DB:
public void GetColumnsForTableFromDatabase(string tabela)
{
string queryForColumns = "SELECT x.columnName, x.columnOrdinal, x.columnTypeID, x.columnMaxLength, x.columnPrecision, x.columnScale, x.columnAllowNull, x.columnIsIdentity, x.columnFKTable, Case When y.Name Is Null Then 'No' Else 'Yes' End As columnPrimaryKey \r\n";
queryForColumns += "FROM ( select sc.name columnName, sc.colid columnOrdinal, sc.xusertype columnTypeID, sc.length columnMaxLength, sc.xprec columnPrecision, sc.xscale columnScale, sc.isnullable columnAllowNull, (sc.status & 0x80)/0x80 columnIsIdentity, sor.name as columnFKTable, sc.colorder \r\n";
queryForColumns += "FROM [" + cmbBoxDatabases.Text + "].[SYS].[syscolumns] sc \r\n";
queryForColumns += "INNER JOIN [" + cmbBoxDatabases.Text + "].[SYS].[sysobjects] so ON sc.id=so.id \r\n";
queryForColumns += "LEFT OUTER JOIN [" + cmbBoxDatabases.Text + "].[SYS].[sysforeignkeys] sfk ON so.id=sfk.fkeyid AND sc.colid=sfk.fkey \r\n";
queryForColumns += "LEFT OUTER JOIN [" + cmbBoxDatabases.Text + "].[SYS].[sysobjects] sor ON sor.id=sfk.rkeyid \r\n";
queryForColumns += "WHERE SO.Name='" + tabela + "' ) AS x \r\n";
queryForColumns += "LEFT OUTER JOIN \r\n";
queryForColumns += "( SELECT c.name, c.colid \r\n";
queryForColumns += "FROM sysindexes i \r\n";
queryForColumns += "INNER JOIN [" + cmbBoxDatabases.Text + "].[SYS].[sysobjects] t ON i.id = t.id \r\n";
queryForColumns += "INNER JOIN [" + cmbBoxDatabases.Text + "].[SYS].[sysindexkeys] k ON i.indid = k.indid AND i.id = k.ID \r\n";
queryForColumns += "INNER JOIN [" + cmbBoxDatabases.Text + "].[SYS].[syscolumns] c ON c.id = t.id AND c.colid = k.colid \r\n";
queryForColumns += "WHERE i.id = t.id AND i.indid BETWEEN 1 And 254 AND (i.status & 2048) = 2048 AND t.id = OBJECT_ID('" + tabela + "')) As y \r\n";
queryForColumns += "ON x.columnName = y.Name \r\n";
queryForColumns += "ORDER BY x.colorder \r\n";
sqlConn.ConnectionString = getConnectionString();
SqlCommand sqlCom = new SqlCommand(queryForColumns, sqlConn);
SqlDataAdapter sqlDA = new SqlDataAdapter(sqlCom.CommandText, sqlConn);
if (DS.Tables.Contains(tabela))
DS.Tables[tabela].Clear();
sqlConn.Open();
sqlDA.Fill(DS, tabela);
sqlConn.Close();
}
I'm lost here, but on my tests i got the correct result if replace:
queryForColumns += "( SELECT c.name, c.colid \r\n";
queryForColumns += "FROM sysindexes i \r\n";
queryForColumns += "INNER JOIN [" + cmbBoxDatabases.Text + "].[SYS].[sysobjects] t ON i.id = t.id \r\n";
queryForColumns += "INNER JOIN [" + cmbBoxDatabases.Text + "].[SYS].[sysindexkeys] k ON i.indid = k.indid AND i.id = k.ID \r\n";
queryForColumns += "INNER JOIN [" + cmbBoxDatabases.Text + "].[SYS].[syscolumns] c ON c.id = t.id AND c.colid = k.colid \r\n";
queryForColumns += "WHERE i.id = t.id AND i.indid BETWEEN 1 And 254 AND (i.status & 2048) = 2048 AND t.id = OBJECT_ID('" + tabela + "')) As y \r\n";
with this:
queryForColumns += " ( SELECT 'centroID' as name, 1 as columnID) As y ";
i know this is strange, but it works, it leads me to think that this has something to do with the 'LEFT JOIN'.
Thanks for the help in advance,
Chapas

Have you grabbed the exec from Profiler and run it in QA/MS.

Hi,
thanks for your reply,
yes i've taken the result obtained from the profiler, during the the debug of my program, and paste it to QA/MS and result was the expected, in the debugger was not the same doe.

Perhaps something odd is happening caused by the way you are building up the query string (not particularly good practice...). Try building up the query in a StringBuilder using the Append method, and pass it to the SqlCommand Object using StringBuilder.ToString() , and omit the "\r\n" business (SQL doesn't need them, if you want them to ease debugging, then use Environment.Newline constant instead). Also consider trimming the variable strings before using them in the query, just to insure there are no stray leading or trailing spaces.

I love this place, you learn something new every day, I have the control \r\n characters coming from a VB background, this looks like the old VBNewLine.

Thanks a lot,
this seems to solve my issue, using the StringBuilder and the Append method.
Don't know how to explain this issue, but the data from the DB got correctly to my app.

Huh? What is it you are trying to do? Learn how to make a simple table? If so, there's plenty of good resources ( google, books, etc )...

If you need a sample database, you can use for example Northwind database provided by Microsoft. Found here: Sample Databases[^]
