In SQL server there are decimal and money data type to store precision and scale both together or say decimal values. Suppose we want to get precision and scale separately then how to get it.
There are many ways to do this but there is a function in SQL named PARSENAME which can be used to get our result, see this
Declare @price Decimal(10,2) Set @price=12345678.90 Select PARSENAME(@price,2) AS [Precision], PARSENAME(@price,1) AS [Scale] OUTPUT: Precision Scale ------------ ------- 12345678 90
Syntax: PARSENAME ( 'objectname' , objectpiece )
Actually it used to get four part of an object separated by dot,
Say we have a string "100.200.300.400" and want to separate them then
Declare @str varchar(100) Set @str = '100.200.300.400' Select PARSENAME(@str, 4) [First] , PARSENAME(@str, 3) [Second] , PARSENAME(@str, 2) [Third] , PARSENAME(@str, 1) [Fourth] OUTPUT First | Second | Third | Fourth ---------------------------------------- 100 | 200 | 300 | 400
PARSENAME function can be used in many situations, say you have an IP address and you want to separate them then it will be very handy, other cases may be to get object name, schema name and database name from complete database and object name say 'master.dbo.person' etc.
