run code to see if a query has results

1 New Member
I have a query that compares two different tables, I have a button on a form that will open the query but I only want the query if it has results. I don't want it to open if the results are null. just have a message box pop up stating there are is no data.
I am thinking: if qry1=null then msgbx "no results" else docmd.openquery "qry1"

Hi, I'm running queries with MySql 4.0.17 that return thousands of records. Because I need to present them in GUI, I returieve the results in chunks using LIMIT, for example - get first 100, then the range 100-2000 and so on. The problem is as follows: in the first chunk, MySQL uses one strategy to fetch the results, and in the following chunks - a different strategy.

I doubt this is the best way to do it, but what I came up with was to hide the XML in an HTML Comment then edit the file deleting the HTML stuff and keep the XML results. If anyone has a better solution, I would be interested. Thank you. Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim cmd As System.Data.SqlClient.SqlCommand cmd = New System.Data.SqlClient.SqlCommand

I'm an experienced Access user, but very new to coding VBA in Access. I'd like to do the following: 1) Develop a basic query in the query designer. 2) Call that query from a VBA script 3) Manipulate the data from the results set in the VBA script (i.e. read data from fields into variables, etc.) This conceptually seems like it should be an easy thing to do. However, I'm finding it difficult to find articles or postings on the subject.

Hello! The reference database I currently use runs queries that pull data from hundreds of tables in order to create user-friendly form view. The problem is that these queries can take upwards of 30 seconds to return. The solution that I've devised is to create an admin function to cache all these query results and then dump that data into a new, consolidated table, and then have the users search through those new tables. Since our...

Hi everybody, just would like to ask to someone more expert than me if it's possible to use a variable (or maybe better, array) as name of the column from which I should get the results with the query. So I mean instead of this: while ($results = mysql_fetch_array($query)) { $id = $results; $name = $results; ...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
