Overview

Syntax	MID(Text, Starting position, Character count)	Returns a specific number of characters from a text string based on the number and position you specify.
Parameter 1	Text	The text string containing the characters to be extracted
Parameter 2	Starting position	The starting point to extract characters. The starting position is 1 at the first character in text, 2 at the second character, and so on.
Parameter 3	Character count	The number of characters to be extracted

Notes

The MID() function supports three parameters. The first one is of the text type and the other two are of the numeric type.
If the value of Starting position is greater than the length of text, the MID() function returns "" (empty text).
If the value of Starting position is less than the length of text, but the value of Starting position plus character count is greater than the length of the text, the MID() function returns the characters up to the end of text.
If the value of Starting position is less than 1, the MID() function returns no result.
If the character count is less than 0, the MID() function returns no result.
If any parameter value is NULL, the result is NULL.
