![]() The AUTOINCREMENT feature in SQLite works differently than it does in MySQL. Sqlite AutoIncrement bug when more than one primary key Issue 15497 dotnet/efcore GitHub. The PRIMARY KEY columns of a WITHOUT ROWID table are also required to be non-NULL. When ID=1 does not exist, the role will be set to 'Benchwarmer' instead of the default value. How do I create an AUTOINCREMENT field What datatypes does SQLite support SQLite lets me insert a string into a database column of type integer Why doesnt SQLite allow me to use 0 and 0. The value of an INTEGER PRIMARY KEY column must always be a non-NULL integer. When ID=1 exists, the ROLE will be unaffected. Solution 2 For example when creating the table with T-SQL use the IDENTITY keyword for the proper column. INSERT OR REPLACE INTO Employee (id, role, name) Problem is the auto-increment does not work. The SQL query for table creation is included. When ID=1 does not exist, the name will be the default (NULL). SQLite PRIMARY key AutoIncrement doesn't work Ask Question Asked 8 years ago Modified 8 years ago Viewed 8k times 4 I'm trying to a have a table with an auto incremented primary key. For example, a numeric primary key in SQL Server is automatically set up to be an IDENTITY column. When ID=1 exists, the NAME will be unaffected. For non-composite numeric and GUID primary keys, EF Core sets up value generation for you by convention. GOOD but tedious: This will update 2 of the columns. UPSERT in SQLite follows the syntax established by PostgreSQL. UPSERT is a special syntax addition to INSERT that causes the INSERT to behave as an UPDATE or a no-op if the INSERT would violate a uniqueness constraint. At the point when we declared column data type as INTEGER with PRIMARY KEY constraint, then it will automatically increment. UPSERT support in SQLite! UPSERT syntax was added to SQLite with version 3.24.0! the NAME column will be set to NULL or the default value: INSERT OR REPLACE INTO Employee (id, role) Assuming three columns in the table: ID, NAME, ROLEīAD: This will insert or replace all columns with new values for ID=1: INSERT OR REPLACE INTO Employee (id, name, role)īAD: This will insert or replace 2 of the columns. ![]()
