This Access tutorial explains how to use Access MID Function to extract substring from a string.
Access MID Function
MID Function is quite similar to LEFT Function and RIGHT Function, where RIGHT Function extracts a substring on the right, LEFT Function extracts a substring on the left, while MID extracts a substring in the middle of the string. Other than Access, Mid Function can also be used in Excel worksheet, Excel / Access VBA.
