Hi there

This code is from Microsoft Library

Dim dbs As Database
Dim qdf As QueryDef

' Modify this line to include the path to Northwind
' on your computer.
Set dbs = OpenDatabase("Northwind.mdb")

dbs.Execute "UPDATE Employees " _
& "SET ReportsTo = 5 " _
& "WHERE ReportsTo = 2;"

dbs.Close

Now I have

1 Form with 1 Text box and 1 botton

Everything is fine but what if this is a btnUpdate_Click() event on a form
And the "SetReportTo = 5" is a txtBox instead

Ho do you insert into sql string parameter from text box in a Form?

Thanks,
Ed Dror

If the field in the table is a numeric type:

dbs.Execute "UPDATE Employees " _
& "SET ReportsTo = " & Me.txtNewValue _
& " WHERE ReportsTo = " & Me.txtOldValue

If it is type Text:

dbs.Execute "UPDATE Employees " _
& "SET ReportsTo = """ & Me.txtNewValue & """ " _
& " WHERE ReportsTo = """ & Me.txtOldValue & """ "
 
Marsh,

I'm getting runtime error 3734
The database has been placed in a state by user Admin on machine
"my computer name" that prevent it from being opened or locked

Private Sub btnUpdate_Click()
Dim dbs As Database
Dim qdf As QueryDef

Set dbs = OpenDatabase("C:\Documents and Settings\Ed
Dror\Desktop\WeeklySalary_GRN_PGR.mdb")

dbs.Execute "UPDATE PaychexData " _
& "SET SQFT = """ & Me.txtSQFT & """ " _
& " WHERE DIV = """ & Me.txtDIV & """ "
dbs.Close
End Sub

Is there any way to set the database as current database and prevent this
from happening?

Like :

Dim strSQL As string

strSQL = "UPDATE PaychexData " _
& "SET SQFT = """ & Me.txtSQFT & """ " _
& " WHERE DIV = """ & Me.txtDIV & """ "
DoCmd.RunSQL (strSQL)

But I'm getting 0 update!

Thanks,

UsingRunSQL will not get close to doing what you want.

Sorry, I have no idea what that means, probably the database
is already open from somewhere else (in your program???)
 
Hello Ed,

If you try to use the code to open a new database, can you reproduce the
problem? If the issue only occurs with specific database, you may want to
copy the database to a different folder and open it from there to test.

Please let's know if you have any update. Thank you.
