问题 I have a database in access where I log maps which I loan out. So I have a table called MapsOut, with fields, MapNum(The map ID), MapName (Name of the Map), CheckOut (Date the Maps were loaned out), CheckIn (Date the Maps were returned). MapNum MapName CheckOut CheckIn 1 London 01/02/13 07/05/13 1 London 08/05/13 16/06/13 1 London 19/07/13 2 Hull 30/01/13 05/03/13 2 Hull 06/04/13 01/05/13 3 Derby 11/01/13 17/02/13 3 Derby 05/09/13 06/10/13 4 Hove 01/02/13 01/03/13 I want to write a query that

问题 In Access, I have a field like this: From the start until end at 01/05/2013, the XXXXXXX device was used. I'm looking for a query that can extract the device name (in this case XXXXXXX). I was able to use mid() to get it somewhat working, but the sentence could be longer or shorter. What are some other ways to do this? Is there a find() I can use to find the location of "device"? My SQL looks like: SELECT Mid(Note, 68, 30) FROM My_Log WHERE Note LIKE "*, the*" ; 回答1: If the device name is the

问题 I have one application in which I need to delete table if exit in Microsoft Access Database. I saw the code here. The table name which I want to delete is data_table and the access database file name is local_entry so where I need to change the code so it work for my application. public void testDropTable () throws SQLException{ Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); Connection con = DriverManager.getConnection("jdbc:odbc:MsAccessDSN"); Statement stmt = con.createStatement();

问题 I am having an issue removing the master -> child link fields in an access subreport data form. I have tried every avenue to remove them, using the properties window of the subreport as well as the link wizard. I have also deleted the subreport from the database and then gone as far as re-importing the existing objects into a new access instance. As soon as I re-added the subform back in and name it the same name the link fields show back up. Something is apparently corrupt, but I have run

问题 I'm having problems with a cascading combo box. Everything works fine with the combo boxes and the values get populated correctly. Private Sub cmbAdjComp_AfterUpdate() Me.cboAdjOff.RowSource = "SELECT AdjusterCompanyOffice.ID, AdjusterCompanyOffice.Address1, AdjusterCompanyOffice.Address2, AdjusterCompanyOffice.Address3, AdjusterCompanyOffice.Address4, AdjusterCompanyOffice.Address5 FROM" & _ " AdjusterCompanyOffice WHERE AdjusterCompanyOffice.AdjCompID = " & Me.cmbAdjComp.Column(1) & _ "

问题 I am setting up a Audit Tracking system for the forms in my database. I am following the example from Susan Harkins Here My code works for my form customers which is based off the customers table. Here is my code: Const cDQ As String = """" Sub AuditTrail(frm As Form, recordid As Control) 'Track changes to data. 'recordid identifies the pk field's corresponding 'control in frm, in order to id record. Dim ctl As Control Dim varBefore As Variant Dim varAfter As Variant Dim strControlName As

问题 I am using Access 2007 and need help creating a query. If this is crazy long, sorry! I figure the more details the better understanding. I am not a programmer--I hope someone will help. I need to know how to collapse/summarize/roll up non-numeric data into a single row that shares a characteristic/value. What I want is like a crosstab query because I want unique cell values from different rows pivoted/displayed in columns along one row for that shared/common value. However, my data isn't

问题 I have an MS ACCESS Table with a string field i use to store dates (I have my reasons to not use a type Date), Is there a way to select rows from the table between two dates ? cuz everything i tried doesnt seem to work, it confuses years, days and months, here is what i tried : select * from audience where Format(auddate, "dd/MM/yyyy") between #01/06/2014# and #01/08/2014# select * from audience where Format(auddate, "dd/MM/yyyy") > #01/06/2014# and Format(auddate, "dd/MM/yyyy") > #01/08/2014

问题 Thanks to a great answer to a previous question (thanks Hansup and Remou), I've made an Access form based on a ADODB recordset that pulls at runtime. This enables it to have a checkbox that is only in memory. The checkbox is fine. I've now been asked to add a drop-down filter by "Client" to the form. Easy enough. I made the drop-down box, made a little query for the control source, and in the After_Update event, added this code: Private Sub Combo_PickClient_AfterUpdate() Me.Filter = "Client='

问题 I have this SQL: SELECT (Min(Time_In) & " to " & Max(Time_Out)) AS [Week Of], Round((Sum(DATEDIFF("n", Time_In, Time_Out))/Count(DATEDIFF("n", Time_In, Time_Out))),2) AS [Avg Min of Jog] FROM SomeTable WHERE len(Time_In) > 0 AND len(Time_Out) > 0 AND #01/01/2012# <= Time_In AND #12/31/2012# >= Time_In GROUP BY DatePart('ww',Time_In); Which picks out average times of a jog per week. I would also like to include a count how many times jogged per week, which I'm trying to do by counting the jog
