MSSQL - Reset Identity Column Value in SQL Server

Command to reset identity column:

DBCC CHECKIDENT(table_name,RESEED,0) 1 is the next value of your identity column.

Example.
Column "id" in table "customer" is an identity column.

DBCC CHECKIDENT("customer",RESEED,0) -> next id is 1.

or

DBCC CHECKIDENT("customer",RESEED,10) -> next id is 11.

If you need to check next ID you can use

DBCC CHECKIDENT("customer",NORESEED) -> you'll get these result.

"Checking identity information: current identity value '0', current column value '0'.
DBCC execution completed. If DBCC printed error messages, contact your system administrator."

Or you can use this SQL statement to get the current identity:

Example.
SELECT IDENT_CURRENT ('customer') AS Current_Identity

Groovy Script which writes data from property "fetchData" in an attachment format. This example will focus on step 2 - Loop Process Call & Local Integration Process. # Local Integration Process "Fetch Data from SF".  How does it work? 1. Use Request Reply to call SuccessFactor to get data 500 records per request. 2. Use Groovy Script to get some fields and return in XML format. 3. Use XML to CS...
