Hi Friends,
My database has emergency mode. I tried to following commands using alter database to online,
ALTER DATABASE 'MYDATABASENAME' SET ONLINE
But it has processing when it has taking more time.
How to solve this?
Thanks in advance,

Is there a way to make a database connection more dynamic, so that the database could be moved to a different directory and still function without requiring the need to change the path in the database code itself? The code I have so far is static and requires changing each time the MS Access file moves or is moved to a different directory.
Dim strDBPath As String
strDBPath = "J:\GELCO DATABASE\Headcount Database\Headcount Database.mdb"
Set dbsHeadcount = OpenDatabase(strDBPath)

usually, connection strings, paths, etc are stored in configuration files so changing them does not require changing code.
You should adopt this practice in general.

Could you explain where the configuration file is in Microsoft Access? I understand in a web application, there is a configuration file, but what about in a networked version of MS Access?

I inherited a job including updating website. the website has a login page. When a client logs in the page will show all there orders. Our staff has to also go in and view there orders. The way it is set up know is the staff member has to look up each clients user id and password in order to view orders. I want a quick and dirty way to allow the staff member to use a global password to get into any account. How would I do this. The page offers a SQL statement that grabs the info. Found here
"SELECT * FROM WSUSER WHERE U_ID='"+ REQUEST.QueryString("U_ID") +"' AND U_PASSWORD ='"+ REQUEST.QueryString("U_PASSWORD") +"'"
Is there a way to change this to also grab the record if U_PASSWORD is a Global password like PASSWORD?

Hi Cory
Try entering
' or '' = ' as the password .... then read Angus' article about SQL Injection attacks[^]. If you still want a global password then tack the following to the end of your SQL.
OR U_PASSWORD = 'MyGlobalPassword'
Regards
Andy

When I put OR U_PASSWORD = 'MyGlobalPassword' at the end of the SQL statement it allows all passwords to work even blank ones. In the following where do I place this at?
SQLS="SELECT * FROM WSUSER WHERE U_ID='"+ REQUEST.QueryString("U_ID") +"' AND U_PASSWORD ='"+ REQUEST.QueryString("U_PASSWORD") +"'"
|
|

Hi Cory
Try:
SQLS = "SELECT * FROM WSUSER " & _
"WHERE U_ID = @U_ID " & _
"AND @U_PASSWORD IN (U_PASSWORD, 'MyGlobalPassword') then setup a SqlCommand with SqlParameters for @U_ID and @U_PASSWORD. That will remove your SQL injection problem.
You will probably find that posting to the page using Request.Form will be more secure that Request.QueryString too.

Andy

The problem would appear to be that you've posted a C++ question in the SQL forum. Please choose a more appropriate one. Just because you've used the word Recordset in the post doesn't actually make this a database issue. It's still C++.

excuse me
but i have found that when i do nothing to the database in a WM_TIMER function, there is no error,
but just if i do something, for example:
void CSerialRecieveDlg::OnTimer(UINT nIDEvent){
CString str;
CCreateName Dlg;
CString TB_Name;
TB_Name=Dlg.m_TableName;
str.Format("SELECT * FROM ");
str+=TB_Name;
try
{
//先关闭已经打开的记录集对象
m_pRecordset->Close();
//根据新的Sql查询语句，重新打开记录集对象
m_pRecordset->Open(str.AllocSysString(),
theApp.m_pConnection.GetInterfacePtr(),
adOpenDynamic,
adLockOptimistic,
adCmdText);
}
catch(_com_error *e)
{
AfxMessageBox(e->ErrorMessage());
}
m_pRecordset->MoveNext();
CDialog::OnTimer(nIDEvent);
}
there is a runtime error,
The problem is that i do not know it is a database problem or a C++ problem??

I wrote a query for getting some values from database , and and bind it to grid.
Now i want to add new values, but before that i wanna check whether there are entries of the same values...
How can I do this...? a friend suggested to add some conditions to the same stored proc to get this done..
Please help me...?

Do a select to check if the duplicate criteria is there and then insert if nothing matches. You could do this with an IF NOT EXISTS query. Alternatively, create a unique index on these fields and rely on the database catching it.

Are u checking for duplicate values in a Database or a table? If it is a table the you use the following script.
SELECT
count(Column(s))
FROM
table_Name
ORDER BY Column(s)
GROUP BY column(s)
HAVING Count(Column(s)) > 1
Hope this helps.

I am trying to update a record in an Employee work hours table to record the employee time out. I need to find the last time the employee clocked in then assosciate the time out with the record. thus having a time in and timeout data.
UPDATE dbo.EmpWorkHours
SET Emp_Timeout = getdate()
where Emp_Timeout in (SELECT TOP 1 Emp_timeout
FROM dbo.EmpWorkHours
WHERE FK_Emp_Login_ID = 'MDoe74'
and Emp_Timeout IS NULL
ORDER BY RecordNum DESC
)
The script looks like it should be doing what I want it to do but it never finds any record, thought the record exist.
Any assistance will be great appreciated.

hi
Check whether the field Emp_Timeout is null or ' '(Space) in the table dbo.EmpWorkHours

Thanks for your response. I figured it out, using the code below.
UPDATE dbo.EmpWorkHours
SET Emp_Timeout = getdate()
where RecordNum = (SELECT TOP 1 RecordNum
FROM dbo.EmpWorkHours
WHERE FK_Emp_Login_ID = 'MDoe74'
and Emp_Timeout IS NULL
ORDER BY RecordNum DESC
)
What was wrong with it you may ask? Well, I was selecting the Emp_timeout field which was null. I was then telling to update a record where getdate() equals the value in the Emp_Timeout field. That would never happen because at the time of the query Emp_timeout field is NULL thus it will never equal getdate().
Hope this helps.

Of course it's urgent, whose question isn't ?
Have you considered checking your stored proc to see if the advice the error gives you is correct ? Did you consider posting the proc here so people have something on which to base their attempts to help you ?

This usually means you have a "begin tran" and you either don't have a commit or rollback or they are not getting hit when you execute the stored procedure. Leaving an open transaction on the database will cause major problems since the open transaction will keep others from being able to access the table(s) that were in the transaction.

Have u tried this:
Begin
StoredProc()
IF
@@Error = 0
Commit trans
Else
Rollback Trans
End
Hope this helps.
