问题 In Access, I need to write a SQL query to separate these rate codes into separate fields/columns from looking like this: $= ** ;= AA AC BB1 CA5 CC4 CC5 CC6 CC7 CC9 CD1 CI CR D0 D1 D2 D3 D9 F> F> FA7 FA9 FB1 HA6 KJ P* P? PW PZ QG V4 WJ 1D 2O $= ** ;= AA AJ BB1 CA5 CC4 CC5 CC6 CC7 CC9 CD1 CI CR D. D0 D1 D2 D3 D9 FA7 FA9 FB1 HA6 I} KJ P( PW PZ QG V4 1A 1D 2V 3} To this: AA BB1 CA5 P? AA BB1 CA5 I've researched this topic extensively but there is no question regarding lines with varying figure

问题 I have an append query that is trying to append some records to one of my tables. However, I am getting an error that says “didn’t add 1200 records due to key violations.” 1200 is the total number of records I am trying to append. I don’t understand why I am getting this error because all of my columns in the destination table allow duplicates (even though this append query doesn’t duplicate any information), and if I copy the structure of the table and append the records to that, everything

问题 I understood that it is possible to set a password to an access database to prevent users from opening it. But is it also possible to set a password to prevent people from changing the "current database" options in the "Options" section? I'm looking for a feature similar to Excels "Protect Workbook" method. 回答1: Is this what you are after ? 1.Open Microsoft Access 2010 and open the database that you wish to password protect in exclusive mode. You may do this by selecting Open from the file

问题 I'm trying to get JSON string returned from MS-Access DB Query. I get the recordset ($rs) fine, but trying to loop through to return JSON, without knowing all the fields in recordset. The following returns what I want but in [["aaa":"bbb","ccc":"ddd"]] not the [{ ... }] i'm looking for. $num_columns = $rs->Fields->Count (); //echo $num_columns . "<br>"; $arrColumns = array(); for ($i=0; $i < $num_columns; $i++) { $arrColumns[] = $rs->Fields($i); } $arrResult = array(); while (!$rs->EOF) {

问题 I'm facing a strange issue in MS Access (2016). When I split my database into a frontend and a backend, and encrypt the backend, my frontend fails to open. As I open my frontend after splitting the database and encrypting the backend, I should see linked tables, which should not open until I relink them by entering the encryption password. Instead, I'm always taken to Access's 'file open' menu (Image), as if the frontend never existed! As soon as I decrypt the backend, the frontend starts

问题 I'm using Microsoft Query in Excel to pull data from an Access database. I don't own the Access database, but I have permission to query its tables and queries using my Excel spreadsheet. I'm trying to pull data between tomorrow at 01:00:00 and the following morning at 00:00:00. I've tried everything from WHERE (acct_data.Date Between DATEADD(DAY,1, DateADD(HOUR,1, GETDATE())) And DATEADD(DAY,2, GETDATE()))) to WHERE (acct_data.Date Between DATEADD(DAY,1, DateADD(HOUR,1, GETDATE())) And

问题 I have an Access form that is supposed to close its predecessor - If CurrentProject.AllForms("fmFileCheck").IsLoaded Then DoCmd.Close acForm, "fmFileCheck", acSaveNo Else End If The IF statement works fine (I have injected a message box to test) but the form simply doesn't close. No error message or anything, it just sits there and tants me, like a squirrel taunts a cat. Edit: The form opens on the "current" event of its predecessor and the code above executes on "current" - but if the code
