In Access, the Left function returns the leftmost n characters of a string.
The syntax for the Left function is:
Left ( string, length )
The argument string can be any string expression. However, if string contains Null, Null is returned. The argument length is a Long expression indicating how many characters to return. It must be between 0 and approximately 65,535, inclusive. If length is 0, the return value is a zero-length string. If length is greater than or equal to the number of characters in string, the entire string is returned. To find the number of characters in string, use Len(string).
