If you have table with no. of rows and you want to find out next id, following query can be used to identify:
SELECT IDENT_CURRENT(‘<Table Name>’) + IDENT_INCR(‘<Table Name>’)
You cannot reliably find out the next identity value – until you’ve actually inserted a new row into the table.
From the IDENT_CURRENT documentation:
When the IDENT_CURRENT value is NULL (because the table has never contained rows or has been truncated), the IDENT_CURRENT function returns the seed value.
Happy Coding 🙂
