Solving the String in Access Expression Builder Error

When working with Microsoft Access, many users encounter syntax errors while trying to perform calculations or concatenate strings using the Expression Builder. One common issue arises when trying to combine the current year with user-defined text in the correct format. This guide will walk you through the problem and provide a clear solution.

The Problem: Syntax Error in Concatenation

Imagine you are trying to concatenate the current year with a string phrase. For instance, you want to create a dynamic string like 2022 My Example within the Expression Builder. The initial formula you might use could look something like this:

However, instead of achieving your desired output, you encounter an error message stating:

"The expression you entered contains invalid syntax."

Why This Error Occurs

Function Misuse: In your expression, FormatDate() appears to be an undefined function. The correct function you should use is Format().

Improper Concatenation: Another common mistake is using brackets [] when concatenating strings. In Access, they are typically used for referencing field names rather than including literal strings.

The Solution: Correcting the Expression

To successfully concatenate the current year with your chosen string phrase, follow these simplified steps:

Step 1: Use the Correct Format Function

Replace FormatDate() with the appropriate function, which is Format(). This function takes a date and formats it into a string representation which we can use.

Step 2: Use Quotes for Strings

Instead of using brackets for your string phrase, enclose it within double quotes "". This ensures that Access recognizes it as a string value rather than trying to reference it as a field.

Final Expression

Putting it all together, your corrected expression should look like this:

Use & for concatenation instead of + .

Ensure that your string phrase is enclosed in double quotes for proper formatting.

Conclusion

By following these adjustments, you should be able to generate a dynamic string output without encountering syntax errors in Microsoft Access. Remember, using the right function and syntax is key to successful expressions!
