问题 When I run this query: select character from tbl_Unknown where format(fw,'.###')='48.143' and code='0001' it returns a result in the Access query interface but when I try to run it from Java it doesn't return a result. My table (tbl_Unknown): char_id: autonumber value:1 fw: short text value:'48.1425' Hint:after format it become '48.143'. code: short text value:'0001' character: short text value: 'x' My java code: public static String getLostedCharacter(String font,String fw, String code) {

问题 I am currently working on adding an audit trail to a MS-Access 2010 database and I am struggling with "error 3251 : operation is not supported for this type object" Here is the code of my audit trail module, mostly arranged code coming from web : Public Function auditChanges(RecordID As String, userAction As String, cForm As Form) Dim db As DAO.Database Dim rst As DAO.Recordset Dim ctl As Control Dim userLogin As String Set db = CurrentDb Set rst = db.OpenRecordset("SELECT * FROM T_AUDIT")

问题 I have a column with text in the following format... sweet shop is there a way to convert this directly to it's corresponding text in sql server? (it is actually a linked ms access database so I could also use access too!) (I think this format is also called Numeric character reference and contains the code points of unicode characters) 回答1: Alex K is 99.99% correct, however the conversion would fail if you had Named Codes like   or £ So, here we perform a brute force replace, and then parse

问题 For MS Access 2010, I need a way to flexibly maintain the position and Z-order when a dozen forms are open. There can be multiple instances of the Parent form, and each one can lead to multiple instances of the Child form (some background here). I want the user to be able to choose which form is top-most -- which means I don't want any forms set as Popup . Also, I want the Z-Order essentially preserved when a new Child opens. As the Child opens, the Parent loses the focus; at that point I'd

问题 I've checked stackoverflow a lot in the past and have always been able to find what I've been looking for, but I just can't seem to get this one to work so I'm asking my first question. I'm not really a programmer, but I mentioned Python at work and now I have a Python project. I was actually getting everything figured out alright, but inserting values into a database is throwing me for a loop. The Basic Problem: I have a form built using Python and tkinter. When a button on the form is

问题 I am trying to create a very dynamic macro that will update different tables in a Database, depending on what the user chooses. Each table has of course distinct titles and information. I'm having a problem with the update (when the user adds new records to an old Table). This is part of the code, the problem is when it gets to the ".update", I get the "Operation must use an Updateable Query" error. Dim DBCnn As ADODB.Connection Dim RecSet As ADODB.Recordset Dim sQRY As String Dim FilePath,

问题 I'm using a technique similar to that in Remou's answer to this question to manipulate the propeties of the controls on a subform. Works great as long as the parent form's recordset has at least one record . If the parent form has no records, I get: Error 2455, "You entered an expression that has an invalid reference to the property Form/Report." The error is thrown when I attempt the recursive call. A simplified version of the code is below (I've stripped out error handling & a couple more

问题 I want to be able to convert a Access 2010 database to multiple different older version by using a script So if I feed a 2010 Access to the script I want it to spit out one of the following versions: 2000, 2002, 2003 or 2007. How is this possible? I'm not looking for a complete script, but more a pointer in the right direction or perhaps an example of how it can be done. * EDIT * TmpName = Destination & "\" & dbDisname & "_2002.mdb" If Dir(TmpName) <> "" Then FS.deletefile TmpName End If
