MS Access: Mid Function
Learn how to use the Access Mid function with syntax and examples.
The Microsoft Access Mid function extracts a substring from a string (starting at any position).
The syntax for the Microsoft Access Mid function is:
Mid ( text, start_position, number_of_characters )
Parameters or Arguments
Text is the string that you wish to extract from.
Start_position indicates the position in the string that you will begin extracting from. The first position in the string is 1.
Number_of_characters indicates the number of characters that you wish to extract. If you omit this parameter, the Mid function will return all characters after the start_position.
The Mid function can be used in the following versions of Microsoft Access:
- Access 2013, Access 2010, Access 2007, Access 2003, Access XP, Access 2000
|Mid ("Tech on the Net", 1, 4)||would return "Tech"|
|Mid ("Alphabet", 5, 2)||would return "ab"|
|Mid ("Alphabet", 5)||would return "abet"|
Example (in VBA Code)
The Mid function can be used in VBA code in Microsoft Access. For example:
Dim LResult As String LResult = Mid ("Alphabet", 5, 2)
The variable LResult would now contain the value of "ab".
If you omitted the number_of_characters parameter in the above example:
Dim LResult As String LResult = Mid ("Alphabet", 5)
The variable LResult would now contain the value of "abet", since omitting the final parameter will return all characters after the start_position.
Example (in SQL/Queries)
You can also use the Mid function in a query in Microsoft Access.
