As the name suggested PARSENAME is the SQL Server function which provide help in parsing.
Lets understand this by an example
Suppose , I have an IPAddress variable which I need to parse
DECLARE @IPAddress AS VARCHAR(100)
SET @IPAddress=’412.312.800.713′
SELECT PARSENAME (@IPAddress,1)
The syntax of the parsename is simple
PARSENAME(String,stringPartIndex)
Only few things which I have observed and limitation of parse name
1) It only works with dot (“.”) delimiter
2) It can parse up to 4 value only
3) Index will start from 1
see the result of above example below
Enjoy !!!
Thanks
