问题 I am getting pretty desperate trying to get this trivial search to work: rst2.Find "ID = '" & messID & "'" I have tried just about any combination but it just never returns a search result. the whole code would be here: Option Compare Database Option Explicit 'Modul zum Updaten des Status eines Messmittels in der Stammdatenbank (Entnommen/Verfügbar)3 Public Function updateStatus() Dim rst2 As ADODB.Recordset Dim rst As ADODB.Recordset Dim messID As String Set rst = New ADODB.Recordset

问题 I'm using Delphi XE2 and AnyDAC and an MSAccess db. The table 'timea' has 5 fields: Rec_No AutoNumber App text User_ID text PW text Comment memo This code throws the error below. The query works just fine in Access query designer. sql := 'INSERT INTO [timea] (App, User_ID, PW, Comment) VALUES ("zoo", "Bill", "mi7", "Liger");'; adconnection1.ExecSQL(sql); Project PWB.exe raised exception class EMSAccessNativeException with message '[AnyDAC][Phys][ODBC][Microsoft][ODBC Microsoft Access Driver]

问题 I'm developing an application which needs to store large amounts of data. I cannot use SQL Server Express edition since it requires separate installation and our target customers have already loaded us with complaints about our previous release with SQL Server express. Now my choices are between SQL Server compact and Access. We store huge amounts of reporting data (3 million a week). Which database can I use? The application is portable and a product based application. Our company is asking

问题 I need to insert into an access database. But skip the row if column dup is already in the table. What I have so far is this: <cfoutput query="hours"> <cfquery name="Employee" datasource="test"> INSERT INTO Tbl_Hours_Comments (ID, ship_num, dup) values(#hours.id#, #hours.ship#, #hours.dup#) </cfquery> </cfoutput> If I don't make dup a Primary Key. Then it will INSERT duplicates. If I make dup a Primary Key. Then I get an error. I think I need something like MySQL. ON DUPLICATE KEY UPDATE. Or

问题 I am thinking to connect to 2 database in my project in php. one is an existing database from our ticketing system that uses MS ACESS and the other one is the one im using now its MYSQL. The use of the MS access is just to retrieve data from it and the MYSQL will be used to both retrieve and store data. Is it possible to connect to both database at the same time?? 回答1: Short answer: Yes . Long answer: You should ensure that your code always uses connection identifiers to avoid confusion and

问题 Is it possible via code to programmatically (from .NET for example via SQL query) to ask an Access database if it is corrupt or have tables with corrupt rows in it? //Andy 回答1: None of the application/database level objects have such an "isCorrupted" property. Furthermore, corrupted databases do not have a standard behaviour. Depending on the situation, database might not open at all (file is not recognized as a valid mdb file). If it opens, error might occur immediately or when using/opening

问题 I'm using the Microsoft TreeView Control 6.0 in Microsoft Access. It seems to work very well, except that it doesn't seem to have a greyed out state, indicating that some, but not all child nodes are checked. I've looked into using my own images to simulate the checkboxes, but if I do this, I then have to remove the real checkboxes or it looks like I have two checkboxes for each item... but then I don't have any checkboxes and I can't work out how to handle a click on the images. I can find

问题 First time asker, usually I can find the answer by searching, but my google-fu seems weak today. I have an excel workbook connecting to an access 2003 database to insert usage records The code i'm using is: sdbpath = ThisWorkbook.Path & "\Data.mdb" sCommand = "INSERT INTO Usage VALUES('" & Environ("Username") & "',#" & Now() & "#)" Dim dbCon As New ADODB.Connection Dim dbCommand As New ADODB.Command dbCon.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & sdbpath & "; Jet OLEDB:Database

问题 I read in a node from a xml file and try to parse one of its attributes to a single. Dim x_coord_single As Single Dim x_coord_string As String x_coord_string = node.Attributes.getNamedItem("x_coord").Text x_coord_single = CSng(x_coord_string ) After i assign x_coord_string it equals "9.0647" But the CSng function returns 90647 I would expect x_coord_single to be 9.0647 . I tried CSng("9.0647") directly but it's the same outcome. Any suggestions on why it is not? I'm working with MS Access

问题 I created a Form in which I created a button and through the context menu I activated the Code-generator for VBA. On a click on the button, the query is correctly exported as .xlsx: Option Compare Database Private Sub Befehl0_Click() DoCmd.TransferSpreadsheet acExport, , "queryname", "C:\test\queryname.xlsx", -1 End Sub However, when I modify the export (according to this FAQ): Option Compare Database Private Sub Befehl0_Click() DoCmd.TransferText acExportDelim, , "queryname", "C:\test
