what will append if have an SQL server table with an identity column (says an int) that reaches the maximal capacity of the int ?

Go back to the beginning ?

Assume that the lines grow 100 by 100. Each time I insert 100 new lines, I delete the 100 old ones.

Answer 1

You’ll get an arithmetic overflow error when you exceed the max int value.

Try it:

DECLARE @t TABLE (
    id INT IDENTITY (2147483647,1), 
    name VARCHAR(100)
)


INSERT INTO @t (name) VALUES ('Joe')  
INSERT INTO @t (name) VALUES ('Tim')
