问题 I like to export data (single records) from one Access database to another one in another country. The idea is that I want to send a text file with INSERT INTO statements per email and the receiving PC just executes these INSERT INTO statements. I wrote already the code to read and execute the INSERT INTO statements in these text files. Obviously I have to generate the INSERT INTO statements. Here is an example. I have the following table: Table1 Id number PersonName text DoB date, can be

问题 I have a front-end Access 2007 database connecting to MySql tables using MySQL ODBC connector. The problem is that a form linked to a table will not refresh its data if the data are changed by another user on the network or if the data was changed by a pop-up form. If I create a VBA code which detects the change and then refresh the form or requery, then the form which shows many records in a table like format, will jump to its top, and some users will lose the sight of the record which is

问题 In an already existing table I would like to create a new column containing the name of the query I am using. For example: ID Name ----------- 1 Max 2 Jack The desired output is: ID Name Query ------------------- 1 Max QueryName 2 Jack QueryName 回答1: I think you can use a static value field in your query, like this: SELECT ID, NAME, "QueryName" AS Query FROM yourTable; When you just want to add a column with a static value in result of querying a table, above is the solution, If you want to

问题 I'm trying to test a query using 'like' but i'm not getting any results back. I tried using UPPER() but when I executed the query, access said that UPPER was undefined?

问题 Not sure why my field in my query is getting truncated upon the return of the result. The value is being stored in the field, but gets truncated by access to help with "performance". I have reviewed multiple forums and SO posts to no avail. Problems listed at link do not apply, Aggregation, Uniqueness, Union, Format Property, Row Source What is wrong with my query? Instructions field in the Customer table is the one that is getting truncated. Here is the raw query generated by access: SELECT

The issue I'm running into now is that I created a simplistic front end for another team to use but I now need to

But when I view Main in Design mode, and click 'Link Master Fields' in the properties for the Action subform, I get this error message: Can't build a link between unbound forms. How can I set up

问题 I've been working on this for the past 6 hours and I'm getting a frustrating error.
