How to Update a SQL Table with VBA in Excel: A Step-by-Step Guide
Are you trying to update a SQL table with information from an Excel worksheet using VBA and find yourself hitting roadblocks? You're not alone! Many users encounter challenges when attempting to leverage Excel for database management tasks. In this guide, we will walk through a common scenario where an end user needs to change a cost in Excel before updating a SQL Server table.
The Problem
You have a project that tracks profit and loss from a billing perspective. As part of this project, you're trying to update a SQL table based on a value that may change frequently in your Excel workbook. The issue arises when you run your macro, and it does not update the SQL table as expected. This can be frustrating, especially if you're new to VBA.
Here's a simplified version of what your macro looks like:

The Solution
Understanding What Went Wrong
The initial problem with your code is the usage of a For Loop. A For Loop is typically used to iterate over a series of values. Since you are running a single update statement, the loop is unnecessary and likely causing the code to malfunction.
Key Points:
For Loop Usage: For updating a single record, a For Loop should not be used.
Error in Loop Condition: The condition For i = 2 To Range("B2").Select unintentionally attempts to loop from 2 to a Boolean value (True/False), which is not valid in this context.
Step-by-Step Fix
Remove the For Loop: Since you only need to run a single update command, simply remove the For Loop and associated Next i statement.
Refactor the Code: Here’s the revised version of your macro:

Test Your Code
After making the changes, run the macro. If there are no other issues, this should successfully update your SQL table with the current value from Sheet3 cell B2.
Conclusion
Updating a SQL table from an Excel worksheet using VBA can be straightforward if approached correctly. By understanding the logic behind your code and avoiding unnecessary loops, you streamline the process.
If you encounter further issues, don't hesitate to revisit your SQL statement and check database connectivity. Always ensure you handle potential exceptions gracefully.
Happy coding!
