Table Valued Parameters


Table Valued parameters are user defined table types and used to pass multiple rows  of data  as input to procedure or function.  

Benefits 

* we dont need many parameters
* we dont need temporary tables
* We dont need XML to pass multiple values
* pass multiple values of different data types
* Enable client to specify sort order and unique keys
* SQL 2012 onwards table valued parameters are cached for all queries.
