Explanation: 

The SUBSTR(string, start position, number of characters) function accepts three parameters and returns a string consisting of the number of characters extracted from the source string, beginning at the specified start position: 

substr('http://www.domain.com', 12, 6) = domain 

The position at which the first character of the returned string begins. 

When position is 0 (zero), then it is treated as 1. 

When position is positive, then the function counts from the beginning of string to find the first character. 

When position is negative, then the function counts backward from the end of string. substring_length 

The length of the returned string. SUBSTR calculates lengths using characters as defined by the input character set. SUBSTRB uses bytes instead of characters. SUBSTRC uses 

Unicode complete characters. 

SUBSTR2 uses UCS2 code points. SUBSTR4 uses UCS4 code points. 

When you do not specify a value for this argument, then the function 

The INSTR(source string, search item, [start position], [nth occurrence of search item]) function returns a number that represents the position in the source string, beginning from the given start position, where the nth occurrence of the search item begins:
