问题 I am building a query to search for records matching any number of fields in a table with 15+ columns. (All fields for which an input is given must match.) However, the original table was badly designed, in some cases having upwards of ten fields for the same thing. (With names such as Street_11.) I have separated the data into multiple tables such that Street_2 through Street_12 are now all labeled under Street_2 in a separate table, containing only that column and fileID , which is taken

问题 In my master database I have a small table that contains two dates and ID numbers. I use this table for updating queries and do some analysis. The table looks like this: Number | Date 1 | 09.07.2012. 2 | 10.07.2012. The thing I would like to do is to have an excel file that pops-up a form after startup. That form should contain 2 fields and 2 buttons. In those fields I input 2 dates (with date picker or whatever) and with 1st button I update mentioned table in Access with fresh data (delete

问题 I want to select the entire first row of each record where a promo code is unique. I am trying to create a samples table, in this table will be one record (the first record) from each distinct promo code. I have asked all of my co-workers and they usually go though the data by hand and select one from each. the problem is that the number of promo codes grows each time and the codes change. so I want to write a query that will select the first record found to have each distinct code. so for I

问题 I having problem on deleting a row of data returned by a search query. I wish the user can select whichever row of data and click on the delete button [button1_click] to delete it from DB.

问题 I am working on a Microsoft Access Database (Office 2010) and I have a tab control on the bottom of my form that displays equipment information based on the type of equipment you select.

问题 For auto date\time we use TIMESTAMP datatype in SQL. What is equivalent to that datatype in MS Access 2007... 回答1: There is no exact equivalent in Access. To clarify, TIMESTAMP in SQL is not always a usable Date/Time, for instance in SQL Server it is deprecated and equivalent to ROWVERSION , which always returns a unique value and it not used to track date and time, even though its value is loosely derived from the current time. But let's say you want to track changes to records. In Access,

问题 I have converted an Access db (.mdb) to SQL Server. In the meantime I still need to use Access as a front end until new application forms are constructed. Can someone tell me what I might do to fix the situation where: In Access 2007, a query such as: SELECT * FROM TransactionTotals WHERE TransactionTotals.[Date]= Date() ORDER BY TransactionTotals.EntryID DESC; worked, however since the Date() function will not work with SQL Server, with help in a previous post the correct syntax is: SELECT *

问题 From a quick google i found out how to use ADOX to create a new database and add some tabels and rows to it. Here is an example: using ADOX; ... ADOX.Catalog cat = new ADOX.Catalog(); cat.Create("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=mydb.accdb;"); Table mainTable = new Table(); mainTable.Name = "Test Table"; mainTable.Columns.Append("Column_1"); cat.Tables.Append(mainTable); This creates a new database and works with that newly created database but If I had an existing database, how
