Different developers have their own ways of doing things and this is reflected in their coding style. What you will see here is the way I like to write my code. SQL statements can also be quite long, and for that reason they are usually assigned to text variables so that they are easier to handle.

Compare these two statements: Lastname from tblStaff where tblStaff. Access only demands that you do this when your field names contain spaces. The brackets tell Access that all the words in the field name belong together. They also tell Access that "this is a field name" and so allows you to use otherwise reserved words for the names of fields such as [Date] which is also the name of a function without causing conflicts.

But I do this for another reason too. This makes long statements much easier to read and edit The statement itself needs to be enclosed in quotes because it is a VBA text string.

If you use the same type of quote mark for each Access will get confused. Look at this example Compare the two examples below. The VBA sees a text string enclosed by double quotes, inside which is some more text enclosed in single quotes.

I working with multiple sets of quotes gets confusing, you can always use the ASCII character code for the double quote mark - Chr 34 - instead.

There is an example of this in the next section. Putting It All Together Some of these rules are essential, others are just my way of doing things and that of many other database developers. The illustration below shows a completed SQL statement written the way I suggest [click the thumbnail to see a full-sized image]: You might be changing the criteria, fields or even data sources specified in your SQL statements each time the code is run.

The information that the SQL statement needs is often obtained from the user through their choices in a dialog box or from the values in fields on a form. Forthcoming tutorials in this series will show how this can be done. You want to allow the user to choose a value for the Office criteria each time the query is run, so you build a dialog box in which there is a combo box containing a list of Offices.

The combo box is named cboOffice.With VBA you can use the Microsoft Excel Application object to create an Excel spreadsheet from Access.

The Excel application object is the entry point to the rest of the object model. Export data faster to Excel by saving data directly to an Excel spreadsheet. The DATE function can only be used in VBA code in Microsoft Excel.

Let's look at some Excel DATE function examples and explore how to use the DATE function in Excel VBA code: Date() Result: '22/11/' (your answer will vary).

In an Access database I'm writing VBA code to export the data to particular tabs on an Excel worksheet. That part is working fine. But then I want the module to save the Excel template with a new filename - ie to have today's date as the filename.

In Access, programming is the process of adding functionality to your database by using Access macros or Visual Basic for Applications (VBA) code. For example, suppose that you have created a form and a report, and you want to add a command button to the form that, when clicked, opens the report. With VBA you can use the Microsoft Excel Application object to create an Excel spreadsheet from Access. The Excel application object is the entry point to the rest of the object model. Export data faster to Excel by saving data directly to an Excel spreadsheet. Access 97 opens a new code module window (you will notice that the toolbar and menus change to provide the appropriate VBA editing tools). In Access /XP the Visual Basic Editor window opens with a new module named Module1.

Programming Microsoft Access with VBA can be a lot easier if you know the keyboard shortcuts for the most common commands and tasks and the most common bits of code that you’ll use in the editor and immediate windows as you build and debug your Access application.

available throughout the Visual Basic editor, where you write, edit, and. Set date field to null using VBA in Access For example, a table with a date field initially has nothing, but once a user selects a date, I cannot set it back to blank in VBA (only if user utilizes a form to delete the date.)Reviews: 8.

Once you have this date format code, you can go back to you VBA code and use this as the argument for the ashio-midori.comFormat property. To see how this works in practice, let's go back to the World Cup calendar that I introduce above.
