Is there auto increment in SQL?
The MS SQL Server uses the IDENTITY keyword to perform an auto-increment feature. In the example above, the starting value for IDENTITY is 1, and it will increment by 1 for each new record. Tip: To specify that the "Personid" column should start at value 10 and increment by 5, change it to IDENTITY(10,5) .
Does primary key auto increment SQLite?
On an INSERT, if the ROWID or INTEGER PRIMARY KEY column is not explicitly given a value, then it will be filled automatically with an unused integer, usually one more than the largest ROWID currently in use. This is true regardless of whether or not the AUTOINCREMENT keyword is used.
Does SQLite have sequences?
To create and access a sequence, you must use SQL functionality that is unique to the BDB SQL interface; no corresponding functionality exists in SQLite. The sequence functionality is implemented using SQLite function plugins, as such it is necessary to use the 'select' keyword as a prefix to all sequence APIs.
Does SQLite auto index primary key?
SQLite does not appear to automatically create an index for a primary key column, but perhaps it indexes it anyway, given its purpose? (I will be searching on that column all the time).
