Difference between Thread and Process


A Process is an instance of a running application. And a thread is the Execution stream of the Process. A process can have multiple Thread.

When a process starts a specific memory area is allocated to it. When there are multiple threads in a process, each thread gets a memory for storing the variables in it, and plus they can access the global variables which are common for all the threads.

Thread: is used to execute more than one program at a time. The process can execute a single program.

Thread is a path of execution that runs on the CPU, a process is collection of threads that share the same virtual memory. A process has at least one thread of execution, and a thread always runs in a process context.

DBCC command to RESEED Table Identity Value – Reset Table Identity

Generally,  we are using identity column into table where identity value incrementally inserted.  DBCC command RESEED is used to reseed (reset) column identity. For example, your table has 20 rows that means last identity value is 20. if you want to reseed identity value will be 30, you can run following TSQL. DBCC  CHECKIDENT  ( yourtable ,  reseed ,  29 ); i f You reseed identity value which is below in current table, it will violate   the uniqueness constraint as soon as the values start to duplicate and will generate error. If you delete last row in current table and insert new row into current table, your new inserted identity value will be last (deleted identity value + incremental value). For example, you delete last three rows where Identity value is 20 - 22 ,so if you now insert new row,  identity value will be 23. That means seed value keep into transaction log.
