What does (1,1) mean in SQL? I mean in the following context:
create table PetOwner ( Id int identity(1,1) , Name nvarchar(200) , Policy varchar(40) )

SQL Injection Based on 1=1 is Always True UserId: Then, the SQL statement will look like this: SELECT * FROM Users WHERE UserId = 105 OR 1=1; The SQL above is valid and will return ALL rows from the "Users" table, since OR 1=1 is always TRUE.
In sum, the "where 1=1" is a used as a placeholder for the WHERE clause so that ah-hoc filtering predicates can be easily added to the query, and the query will execute, even in the absence of specified filtering conditions.
Have you ever seen a WHERE 1=1 condition in a SELECT query. I have, within many different queries and across many SQL engines. The condition obviously means WHERE TRUE, so it's just returning the same query result as it would without the WHERE clause.
WHERE 1 is a synonym for "true" or "everything." It's a shortcut so they don't have to remove the where clause from the generated SQL.
In Id int identity(1,1), the first 1 means the starting value of ID and the second 1 means the increment value of ID. It will increment like 1,2,3,4.. If it was (5,2), then, it starts from 5 and increment by 2 like, 5,7,9,11,...
